    FIELD OF THE INVENTION
    [0001] This invention relates to a use of liquid dispenser and in particular to a method of monitoring the use of liquid dispenser that can be correlated to hand hygiene compliance or other liquid dispenser usage compliance. BACKGROUND OF THE INVENTION
    [0002] The spread of health care-acquired infections also known as HAI's has always increased the challenge in medical care facilities. HAI's include the transmission of bacteria, viruses, other bacteria, viruses and other microorganisms causing illness from various sources such as a patient or environmental surfaces to another patient or surface via the hands of medical care workers that result in an infection of a patient who was not infected. These problems have been most apparent in recent years with the outbreak of SARS (severe acute respiratory syndrome) and influenza A H1 N1 pandemic. Likewise, health care facilities have fought MRSA (methicillin-resistant staphylococcus aureus) and VRSA (vancomycin-resistant staphylococcus aureus) and other drug-resistant microorganisms for many years. Consequently, there is a need to ensure that health care professionals are consistent with best hand hygiene practices. Hand hygiene can be performed using liquids such as an antiseptic product that does not require water or rinsing or alternatively it can be washed using soap and water.
    [0003] Likewise, there are other types of liquids that can be distributed such as sunscreen, in which the use of sunscreen in a similar way requires a method of monitoring, tracking and reporting. For example, such a method could be very important in schools in Australia where the incidences of skin cancer are very high. SUMMARY OF THE INVENTION
    [0004] In a first aspect, a group monitoring system is provided for compliance with the use of liquid dispensers within a predetermined group of interest in a type of predetermined installation comprising the steps of: providing a plurality of liquid dispensers, provide an operable liquid dispenser data collection system connected to each liquid dispenser, capable of providing information, information including a unique liquid dispenser identifier for each liquid dispenser, a number of liquid dispenser usage events that each liquid dispenser has been used; receiving information from the data collection system and determining the predetermined group within which each liquid dispenser is associated; determining the number of liquid dispenser usage events within the predetermined group within a predetermined period of time; determine a reference mark that corresponds to the opportunities for using the particular liquid dispenser for the predetermined group and particular for the predetermined period of time; calculate a particular liquid dispenser usage compliance index for the predetermined group and particular for the predetermined time period by dividing the liquid dispenser use events for the predetermined group and the predetermined time period by a denominator where the denominator matches the reference mark.
    [0005] The number of liquid dispenser usage events within a predetermined period of time can equal a number of times that the liquid dispenser has been activated yet a plurality of activations within a predetermined period of activation is considered a single event of using liquid dispenser. The predetermined activation is typically between 1 and 4 seconds.
    [0006] The information can include the type of product in the liquid dispenser and the type of product is typically one of hand soap, antiseptic gel, lotion, cream, sunscreen and body wash.
    [0007] The predetermined time period can be one of a shift, a day of the week, a weekend day, a holiday day each of the predetermined group in the predetermined type of installation.
    [0008] The reference mark may vary depending on the predetermined type of installation. The predetermined type of facility can be one of a health care facility, a food processing facility, a food service facility, an educational facility, and a manufacturing facility. Alternatively, the predetermined type of facility may be one of a teaching hospital, a non-teaching hospital, a facility for long-term medical care, a rehabilitation facility, a surgical center that remains free, a professional office for care of the health, a dental office, a veterinary facility, and a community care facility.
    [0009] Similarly, the reference mark may vary depending on the predetermined group of interest. The predetermined interest group can be one of a medical unit, a surgical unit, a critical medical care unit, an intensive care unit, an emergency care unit, a pediatric unit, an emergency unit, an outpatient unit, a specialty care unit, a dermatology unit, an endocrinology unit, a gastroenterology unit, an internal medicine unit, an oncology unit, a neurology unit, an orthopedic unit, an ophthalmology unit, a throat unit, nose and ear, a neonatal unit, a gynecology and obstetrics unit, a cardiac unit, a psychiatric unit, a postoperative recovery unit, a radiological unit, a plastic surgery unit and a urology unit. The predetermined group can be one of a bed, a room, a ward, a unit, a ward, a facility and a hospital group.
    [0010] The reference mark in the denominator can be multiplied by census data. The census data can be one of hand occupation rate in the predetermined group, days of the patient in the predetermined group, visits to the patient in the predetermined group, hours in bed for medical care in the predetermined group and operational staff in the predetermined group.
    [0011] The group monitoring system for liquid dispenser usage compliance may include the step of determining a hand hygiene compliance index. The hand hygiene compliance index can include information on the use of liquid dispensers only; weighted information from the liquid dispenser usage compliance index and one from inspection compliance data or direct observation compliance data. Alternatively, the hand hygiene compliance index includes weighted information from the liquid dispenser usage compliance index and inspection compliance data and direct observation compliance data.
    [0012] The liquid dispenser data collection system can use a frequency selected within the group consisting of 400 and 450 MHz systems, between 850 and 950 MHz systems and between 2.4 and 2.5 GHz systems. Alternatively, the liquid dispenser data collection system can be a system embedded in a hardware system.
    [0013] The liquid dispenser data collection system can use a system frequency between 850 and 950 MHz and has a transmission power of up to 1000 milliwatts. The data collection system from a plurality of liquid dispensers. Each concentrator receives data from one or more liquid dispensers and the distance between each liquid dispenser and its concentrators associated with the concentrator is no greater than 5,740 feet (1750 m). Data can be encrypted.
    [0014] In another aspect of the group monitoring system for collecting data on the use of the liquid dispenser comprising: a plurality of liquid dispensers each having an operable sensor that can be detached from it to collect data from the dispenser of liquid; a plurality of concentrators capable of receiving data from a plurality of liquid dispensers; and that data is transmitted between 850 and 950 MHz.
    [0015] Data can be encrypted. Each liquid dispenser can have an electricity usage of up to 1000 milliwatts.
    [0016] Additionally features of the invention will be described or will become apparent in the course of the following detailed description. BRIEF DESCRIPTION OF THE DRAWINGS

    [0029] Measuring health workers' adherence to hand hygiene compliance guidelines is not a simple matter. There are no proven standards or benchmarks that can be used. However, there is a very clear need to monitor and measure hand hygiene compliance. Consequently, there is a need to determine whether the hand hygiene action occurred or not when there was an indication for hand hygiene action. The five moments for hand hygiene actions in a health care setting are shown in figure 1. These five moments of hand hygiene were developed by the World Health Organization. Hand hygiene actions can be asepsis with a product antiseptic that does not require water or rinse or alternatively it can be washed with soap and water.
    [0030] As used here, the term "hub" refers to any network device capable of sending and receiving information packets and is not to be construed as limited to Ethernet hubs, network hubs, or repeater hubs traditionally described in computer network literature.
    [0031] As used here, the phrase "operably connected" or "operably attached", e.g. "X is operably connected to Y" or "X is operably attached to Y", indicates that X and Y can casually influence each other in operation, although X and Y do not necessarily have to be physically connected or physically attached. In this sentence, the terms "connected" and "attached" are to be interpreted in an operational sense, and not necessarily a physical sense. For example, if X and Y are devices capable of sending packets to each other either directly or over a network, then X and Y are operably connected. As an additional example, if X is a device and Y is a sensor, and Y is able to perceive one or more events occurring as a result of X's operation, then X and Y are operably connected.
    [0032] Referring to Figure 1 the five moments of hand hygiene action are shown in general in 10. Specifically they are before contact with the patient 12, before the aseptic task 14, after risk of exposure of the body fluid 16 , after contact with patient 18 and after contact with patient's surroundings 20. When considering compliance, if a health care worker only washes or antiseptic gels his hands 6 out of the 10 times they should be, they are said to exhibit a 60% compliance rate.
    [0033] There are a number of ways to measure compliance namely direct observation, remote observation, self-report and use of liquid dispenser data or product usage data. Each way has its own benefits and challenges. Specifically direct observation provides specific information on hand hygiene indication, techniques and behaviors. However, the labor and resources required to collect such data are intensive. In general, if this type of data is collected, only a small sample of the total hand hygiene opportunities is collected and therefore has a typically low level of statistical agreement. The data are subject to the predisposition of over or under sampling of certain shifts and units. Likewise, it has been shown that there are also issues regarding agreement between the evaluator (observer) and, therefore, it is difficult to compare the results of each observer or evaluator with the other.
    [0034] Furthermore, it has been shown that if people know that they are being seen or studied there is a greater likelihood that the compliance rate will be artificially higher than in reality. This is known as the Hawthorne Effect. Supporting evidence for this is found in a German study in 2009 that compared product usage data with direct observation data and found that the direct observation compliance rate was 2.75 times higher than that for product use. So product use is gaining acceptance by professionals as a more accurate measure of true compliance rates.
    [0035] With regard to remote observation such as video the advantage is that it is less subject to predispositions and it can operate at any time of the day or night and in any unit. However, as such a data collection method is expensive because of the installation and maintenance of the video equipment as well as the time to review the video, such a review is then subjected to the same lack of agreement between the evaluator as the direct observation. In addition, it can be subjected to predisposition based on video location. In addition, there may be privacy issues with respect to video locations.
    [0036] With regard to the self-report option, it has the advantage of being low cost and it encourages health care professionals with regard to self-awareness of hand hygiene. However, in general this type of data collection has poor agreement and most experts in the field consider this small, if any, value.
    [0037] In typical healthcare environments, hand hygiene fluids are stored and dispensed in the hands from liquid dispensers, therefore there is a direct correlation between use of liquid dispensers or hand hygiene activations and events being made. Liquid dispenser usage data can provide the volume of product used per patient per day. This has the advantage of being less expensive to monitor. In addition, it provides an overall measure of use and is not subject to selection of predispositions. However, this does not provide feedback for indications or techniques. In addition, it does not identify individual underperforming employees. There are a number of additional advantages for measuring liquid dispenser usage. Specifically in addition to being less expensive it is less resource intensive and therefore more efficient than observation. Likewise it can be done manually or electronically. This allows trends across the organization to be monitored over time. It can be non-obstructive and designed to take up little additional space. Liquid dispenser usage can be easily measured on all shifts, twenty-four hours a day, seven days a week. This requires minimal staff training. This can easily be done in many different health care settings.
    [0038] In the modalities here the liquid dispensers are able to determine when the liquid dispensers are activated. The number of liquid dispenser usage events within a predetermined time period equals the number of times the liquid dispenser has been activated and a plurality of activations within a predetermined activation period is considered a dispenser use event single liquid. It will be appreciated by those skilled in the art that a plurality of activations within a short period of time will typically mean that a user has activated the liquid dispensers a plurality of times more properly than multiple users activating the liquid dispenser in close proximity. Therefore, a plurality of activations within 1 to 4 seconds of frame time will be considered a single liquid dispenser usage event. For hand soaps and antiseptic hand gels in a health care facility, this will typically be set up in 2.5 seconds. However, where liquid dispenser usage is being monitored for different types of products regardless of the types of facilities, this can be configured for a different activation period. Typically liquid dispensers are calibrated to dispense a predetermined amount of liquid for each activation. Consequently, the activation of liquid dispenser directly refers to the use of the product. Consequently, it will be appreciated by those skilled in the art that when determining a liquid dispenser usage compliance index someone could measure used volume or liquid dispenser activations.
    [0039] In a modality use of liquid dispenser alone is used to calculate a liquid dispenser usage compliance index. In another embodiment, the combination of two or more liquid dispenser usage data, direct observation data and inspection data (for example, self-report data or patient inspection data) can be used to provide information consolidated hand hygiene. Preferably the information would be automated and in real time. In one mode, the system would provide hand hygiene compliance reports at multiple automated points. Preferably, these reports could be presented by unit and / or department. Such automated reporting would provide hospital management with the tools to provide feedback on compliance compliance; target interventions designed to improve compliance; and reward improved performance.
    [0040] In one embodiment, the hand hygiene compliance index will include a plurality of ways of determining compliance. Specifically this will include usage data for liquid dispenser, observation and / or inspections. Each method is weighted and then combined to create a unique compliance index. The methods are weighted based, for example, on their statistical agreement.
    [0041] To determine compliance measurement by using liquid dispenser the installation being monitored is provided with a plurality of liquid dispensers. The installation can be divided into predetermined interest groups. The facility may be a teaching hospital, a non-teaching hospital, a facility for long-term medical care, a rehabilitation facility, an operating room that remains free, a professional health care office, a dental office, a veterinary facility and community care facility as well as other health care settings where hand hygiene compliance is an important issue. Alternatively, the system here can be used in any facility, where hand hygiene needs to be monitored as in various stages in food preparation including slaughterhouses, pre-cooked food preparation and restaurants. The monitoring system could also be used to monitor compliance with the application of such lotions dispensed as sunscreen.
    [0042] In order to determine liquid dispenser usage compliance someone needs the number of hand hygiene events and the reference mark for a predetermined area or group and for a predetermined time. Liquid dispenser usage compliance is liquid dispenser usage events divided by a denominator, where the denominator includes at least in part the reference mark. The reference mark is particular for the predetermined group and particular for the predetermined period of time. Usage can be measured for each liquid dispenser in the predetermined group in near real time and the captured data is transmitted electronically. It will be appreciated by those skilled in the art that there is a limited amount of time required for data to be picked up from the liquid dispenser, to the concentrator and to the server (described below) but this could be configured for the messages to be transmitted very often. While access to reports is available twenty-four hours, seven days a week, typically, however, the most likely reports would be submitted no more than daily and most likely weekly or monthly. However, if there is a particular outbreak in a ward, the use of the liquid dispenser could be monitored more frequently by accessing reports on demand. The number of hand hygiene events within a predetermined period of time equals a number of times that the liquid dispenser has been activated and that multiple activations within a predetermined period of activation are considered a liquid dispenser use event single. It is not uncommon that when someone uses a dispensing system that more than merely activates it once, it activates the liquid dispenser several times. Consequently, to precisely determine the correct number of liquid dispenser usage events the number of times the liquid dispenser is activated is determined. However where there are multiple activations within a predetermined period of activation that is considered a single liquid dispenser use event. The benchmark is the number of times the liquid dispenser must have been used for a predetermined group over a predetermined period of time.
    [0043] When liquid dispenser usage compliance refers to hand hygiene compliance in a health care facility, the benchmark refers to the five hand hygiene moments for a predetermined group over a period of predetermined time. To determine the benchmark for the predetermined area and time, one needs to determine the hand hygiene occurrences that must occur per patient for the predetermined area and time. This is done with reference to the five moments of hand hygiene as shown in figure 1. It will be appreciated by those qualified in the technique that the reference mark will be different depending on a number of variables. For example, if the healthcare facility is a teaching facility it is likely that more healthcare professionals will need to see the patient and therefore the benchmark may be higher. The benchmark may vary if the predetermined period is a night shift versus a day shift; whether it's a weekday versus a vacation or weekend day. The reference mark will likely vary depending on the type of unit. For example, an intensive care unit is likely to have a higher benchmark than an orthopedic unit. The denominator may be dependent on the census data. Specifically to determine the denominator the reference mark is multiplied by the census data. For some health care facility units or for the predetermined interest group the census data will be bed occupancy. In some health care facilities or in particular units of the facility it can always be close to 100% while in other units or facilities it can vary enormously. In other units, for example, an emergency unit or an outpatient unit, the census data could be the number of patients seen during the shift or over the predetermined period of time that is in question. It can also be the number of hours of bedtime for medical care provided during the predetermined period of time that is in question.
    [0044] In addition, it will be appreciated by those skilled in the art that the reference mark can be determined through experiments or other means by the health care facility or there may be standard reference marks provided that are provided to the user by the liquid dispenser provider or a central authority.
    [0045] The following are some of the categories that can be used to determine the correct reference mark. The group or types configured below that relate to health care facilities and the types of units within them are the location labels for the Center for Disease Control (CDC) and are for example only. It will be appreciated by those skilled in the art that there are a number of different ways to divide units into a health care facility.

    [0046] Once the multi-point compliance index is calculated a number of different reports could be generated. Reports can be used to help determine where more or different hand hygiene compliance efforts such as the need for additional training are implemented. The reports could be presented in a simple graph format as shown in Figures 2 and 3, in which figure 2 shows the hand hygiene index in the pediatric units when compared to the hospital aggregate and with the objective or benchmark and figure 3 shows the hand hygiene index in the intensive care unit when compared to the hospital's aggregate and the reference objective or brand. Figure 4 shows some different reporting options. Figure 5 shows a panel showing a more comprehensive way of presenting information.
    [0047] It will be appreciated by those skilled in the art that there are a number of different options with respect to how the hand hygiene compliance index can be presented. The representation of the different ways that the hand hygiene compliance index can be displayed is shown in general at 100 in figure 4. For example, the user can use a standard reference mark 102 or a user-defined reference mark 104 when determining liquid dispenser usage compliance. With the standard reference mark, the hand hygiene compliance index can be an index of use compliance for liquid dispenser by proper sign 106 or can include multiple points data. If it includes data from multiple points, the liquid dispenser usage compliance index can be combined with inspection data 108; or with direct observation data 110; or with inspection data and direct observation data 112.
    [0048] Alternatively with the reference mark defined by the user, the hand hygiene compliance index can be presented as the liquid dispenser use compliance index by itself 114; or with inspection data 116; or with direct observation data 118; or with inspection data and direct observation data 120. If the liquid dispenser usage compliance index is combined with other data the data is weighted when it is combined to provide a hand hygiene compliance index.
    [0049] The hand hygiene compliance index (HHCI) can be expressed as an equation. Hand hygiene events or liquid dispenser usage events are used to calculate the HHCI or liquid dispenser usage compliance index. An event is the same as an activation of the liquid dispenser, except in the case where multiple activations occur within a predetermined activation period. The predetermined activation period is between 1 and 4 seconds and preferably 2.5 seconds. Where multiple activations occur within the predetermined activation period, total activations occurring within the predetermined activation period constitute a single hand hygiene event. In those cases of multiple activations within, for example, 2.5 seconds are recorded as a single event with n activations. The events are the ones that are used for the HHCI numerator.
    where: e = end date s = start date events = number of effective hand hygiene events dp = part of the day (eg first round; second round) census = patient for the day part benchmark = expected activations for the part day w1 = the weighting of the particular component. w1 + w2 + w3 must total exactly 1. w2 = the weight of the particular component. w1 + w2 + w3 must total exactly 1. w3 = the weight of the particular component. w1 + w2 + w3 needs to total exactly 1. Direct observation method = observed hand hygiene compliance. An integer between 0 and 100 representing% compliance. Patient Inspection Method = inspection hand hygiene compliance with the patient. An integer between 0 and 100 representing% compliance. The numerator is the sum of events for a predetermined period of time. The denominator represents the total number of hand hygiene events expected for a predetermined period of time. To calculate the denominator, first take the census for a part of the day multiplied by a reference mark for that part of the day. This leads to the number of events expected for that part of the day. The expected events for each part of the day for the predetermined time period are then added together resulting in the expected total activations for the time period defined by that start and end time. Weights are applied by multiplying the weighting for the component's hand hygiene compliance. There are three cases for calculating Hand Hygiene compliance. 1) Activation of Liquid Dispenser In this case w1 is equal to 1 and there is no “observed” or “inspection” hand hygiene component for the index. 2) Activation of Liquid Dispenser and data from Both “Inspection” or “Observed”. In this case w1 and w2 or w3 will total 1, and the index is calculated by multiplying the weighting by the compliance component. For example, Hand Hygiene compliance recorded by the group monitoring system for a period of time is 90 with a weight of 0.8. Inspection Patient Compliance is 70 with a weight of 0.2. With no “observed” data used for calculating the HHCI (hand hygiene compliance index). Recorded Hand Hygiene compliance is 90 x 0.8 or 72 and the inspection patient's Hand Hygiene compliance is 70 x 0.2 or 14. The Hand Hygiene Compliance Index for the time period is 86, or 72 + 14. 3) Liquid Dispenser activations with both “Inspection Patient” and “Observed” compliance data. In this case w1 + w2 + w3 will add up to 1, and the index is calculated by multiplying the weighting by the compliance component.
    [0050] For example, hand hygiene compliance recorded by the group monitoring system for a period of time is 90 with a weighting of 0.6. Inspection Patient compliance is 70 with a weight of 0.2. and observed data compliance is 70 with a weighting of 0.2. Registered hand hygiene compliance is 90 x 0.6 or 54, with inspection patient's hand hygiene compliance is 70 x 0.2 or 14 and observed compliance is 70 x 0.2 or 14. The compliance compliance index hand hygiene for the time period is 82, or 54 + 14 + 14.
    [0051] It will be appreciated by those skilled in the art that there are a wide variety of ways that information can be presented. A sample panel is shown at 130 in figure 5. The sample panel includes a graphical representation of use 132, a summary report 134 and a listing of specific use for liquid dispenser 136.
    [0052] Each liquid dispenser has a unique identifier and the unique identifier that can be associated with a soap liquid dispenser versus an antiseptic gel liquid dispenser. This can be important to differentiate between hand hygiene events using soap versus antiseptic gel. This will particularly be important where the facility has a particular outbreak, which requires soap versus antiseptic gel or vice versa, such as with the difficult clostridium organism (also known as C. diff.) Causing illness that is more difficult to eliminate in the form of spores and can typically be removed from the hands only with hand washing as there is reliable data to support the premise that hand antiseptic gels are not an effective way to kill c. diff.
    [0053] The system can be designated where the facility has the ability to adjust the reference mark or use the reference mark of its own choice. It will be appreciated by those qualified in the technique that the installation will have a wide range of reports that it can generate. For example, it could generate reports per unit; by hospital; compare unit by unit; unit per hospital; or hospital by hospital as an example. Likewise, it will be appreciated by those skilled in the art that the use of data from the liquid dispenser can be integrated with the purchasing department of the facility.
    [0054] The system can be connected to a wired system as shown at 30 in figure 6 or to a wireless system as shown at 50 in figure 7. In wired system 30 a liquid dispenser 32 is connected to a concentrator 34 and / or a connection point 36. The connection point is connected to the data collection server 38, which in turn is connected to a hand hygiene compliance index calculation server 40. Those skilled in the art will appreciate that the data collection server 38 can comprise one or more computers.
    [0055] Similarly in wireless system 50 the liquid dispenser 52 is in wireless mode connected to a hub 54 and / or to a connection point 56. The connection point is in wireless mode connected to a server data collection 58, preferably over the Internet through GSM (Global System for Mobile Terminal Communications) or other communications standards and network protocol. The data collection server 58 is connected to a hand hygiene compliance index calculation server 60. It will be appreciated by those skilled in the art that the data collection server 58 and the compliance conformity index server hand hygiene 60 can be the same server. Each liquid dispenser 52 has a sensor in it that is preferably capable of storing data with respect to up to 100 or more activations. It will be appreciated by those qualified in the technique that 100 is just an example and that typically each liquid dispenser may only need to store data related to few activations. This minimizes the chance of losing data in the queuing event for receipt by the concentrator. The data is sent between the liquid dispenser 52 and concentrator 54 and the concentrator 54 and connection point 56 in bursts that are dependent on either time or memory. Preferably, data is sent from connection point 56 to server 58 in a burst via GSM. Data can be sent to an offsite server 60 for data processing. .
    [0056] While the network is described as a plurality of network devices consisting of hubs and connection points, other network devices can be used. Some non-limiting examples include wireless hubs, Ethernet hubs, repeater hubs, switches, ethernet switches, bridges, routers, Ethernet routers, wireless routers and connection point routers.
    [0057] Those skilled in the art will appreciate that packets can be sent within the aforementioned network using any number of protocols. Optionally, packets can be sent according to the Internet Protocol Group (IPS), which includes the transmission control protocol (TCP) and the Internet Protocol (IP), often called TCP / IP. Compared to the alternatives, this scheme moves a lot from the complexity of the network to the edge of the network, i.e. for each liquid dispenser and for the server. When using this scheme, liquid dispensers can send packets via either TCP or UDP (Usergram Data Protocol), although other transport layer protocols can be used within IPS specifications.
    [0058] Alternatively, packages sent between liquid dispensers, concentrators, and connection points may have a different format than that specified in the IPS specifications, and may eventually be repackaged in IPS-compatible packages when sending the server out from site 60. It may be desirable to send information off site using the Internet Protocol Group as the existing Internet network infrastructure can be used for transmission. When designing a wireless system there are a number of different considerations. Specifically, there are only a limited number of frequencies that are generally available for "unlicensed" broadcasts. The "unlicensed" frequencies that are available in each country may differ. "Unlicensed" frequencies can have a wide range of uses, for example they are used in retail label security systems, garage remote control devices, Wi-Fi networks and many RFID tags (security tags). radio frequency identification device). Preferably the system described here will use an "unlicensed" frequency. As an example in Title 47 part 15 of the USA Code of Federal Regulations covers the use of "unlicensed" transmitters within the United States of America. Specifically, the table below shows a frequency and associated power levels that are generally available.
    * 200u mV / m equals approximately - 10dBm when converted
    [0059] In contrast, European radio regulations are encapsulated by R & TTE (Directive 1999/5 / EC) and supported by CEPT Recommendation 70-03. Compliance with the R & TTE directive can be achieved in 2 ways, the first is by applying "Harmonized Standards" and the second by obtaining Notified Body Approval. The table below is based on the CEPT70-03 recommendation and the Harmonized standards EN300-220 and EN300-440.

    [0060] The frequency and power that are selected affects the system design. A flow chart showing the steps implemented in a low frequency (between 400 and 450 MHz) and low power (up to 10 mW) wireless system is shown in general at 70 in figure 8. A similar flow diagram for a wireless system highest frequency (between 850 and 950 MHz) and highest power (up to 1 W) is shown in general at 140 in figure 9.
    [0061] A flowchart showing the implemented steps of a low frequency (between 400 and 450 MHz) and low power (up to 10 mW) wireless system is shown in general at 70 in figure 8. Since there was an event of using liquid dispenser the liquid dispenser ID 52 is transmitted to any and all concentrators 54 within the transmission distance 72. Upon receipt of the transmission of the liquid dispenser ID, the concentrator (s) responds with an acknowledgment message 74. This is sometimes referred to as a "handshake". If an acknowledgment message is not received by the liquid dispenser, the liquid dispenser will hold until successful. The concentrator adds a date and time stamp to the ID to produce usage data for the liquid dispenser. The concentrators 54 send the usage data of the liquid dispenser 76 through the network unit of the concentrator network unit until it reaches a connection point 56. Each successive concentrator 54 in the chain acknowledges receipt of the use data of the liquid dispenser from the concentrator previous 78. If the acknowledgment message is not received by the originating hub, it will retain until successful. The concentrators 54 within the transmission distance of the connection point transmit the usage data of the liquid dispenser data through connection point 80. When the activation data is captured by connection point 56, it transmits an acknowledgment message back for concentrator (s) 82 originating. If an acknowledgment message is not received by the originating hub, it will retain until successful. Connection point 56 arranges all the data it received from the rest of the system in transmission packets of a predetermined format. The predetermined format can specify a predetermined size or a predetermined header size. These data packets are transmitted to the data collection server 84. Preferably the data is sent to the data collection server 58 over the Internet and preferably via GSM. When data packets are received or captured by data collection server 58, an acknowledgment message is sent back to connection point 86. If an acknowledgment message is not received by connection point 56, it will hold until it is Successful. This type of system is often referred to as a mesh network.
    [0062] It will be appreciated that such acknowledgment messages may be either dedicated packages or may be included in a designated space within the package header.
    [0063] Alternatively, acknowledgment messages can be sent from the server back to the liquid dispenser, rather than between each concentrator and liquid dispenser. In this scheme, each hub will forward the acknowledgment message packets to its addressed location, e.g. liquid dispenser or server.
    [0064] Alternatively, a system with a higher frequency (between 850 and 950 MHz) and greater power (up to 1W) is shown in general in 140 in figure 9. In the initial configuration the liquid dispenser 52 sends a request to the concentrator 54 more close to the concentrator's ID (identification) and an updated time 42. The concentrator 54 responds with the requested information 144 and it synchronizes with the liquid dispenser. If the response is not received by the liquid dispenser, it will hold until a successful synchronization is achieved. Once the initial configuration is complete and there has been a liquid dispenser usage event, liquid dispenser 52 transmits 54 liquid dispenser data to its synchronized concentrator including, liquid dispenser ID, time, date of use, events of liquid dispenser usage 146. Upon receipt of liquid dispenser data the concentrator responds with an acknowledgment message 148. The acknowledgment message contains a time update. This is sometimes referred to as a "handshake". If an acknowledgment message is not received by the liquid dispenser, the liquid dispenser will retain until it is successful. The concentrators arrange the data received from the liquid dispensers to form a transmission packet of a predetermined size (predetermined number of bytes) 150. The data packet is then transmitted through the network concentrator until it reaches the connection point 56. As the data packet is captured by the concentrator receiving it transmits an acknowledgment message back to the originator originating 152. This acknowledgment message also contains a time update. If an acknowledgment message is not received by the originating hub, it will retain until successful. The concentrators 54, within the transmission distance of the connection point 56, transmit the data packets to the connection point 154. As the data packet is captured by the connection point it transmits the acknowledgment message back to the concentrator originating 156. This acknowledgment message contains a time update. If the acknowledgment message is not received by the originating hub, it will retain until successful. The connection point stores all the data it received from the rest of the system in a transmission packet of a predetermined size (bytes) 158. This data packet is then transmitted via GSM to the data collection server 58. According to the packet of data is captured the data collection server transmits an acknowledgment message back to connection point 160. This acknowledgment message also contains a time update. If an acknowledgment message is not received by connection point 56, it will retain until successful. This type of system is often referred to as a mesh network.
    [0065] Referring to Figures 10 and 11, examples of the liquid dispenser data collection system are shown in 90 and 96 respectively. A plurality of liquid dispensers 52 are positioned around the unit of the facility being monitored. A plurality of receivers or concentrators 54 are positioned around the unit within the range of the liquid dispensers such that each liquid dispenser is within the reach of at least one receiver. As described above, when each liquid dispenser 52 is used it will transmit its unique identification code, date and time to the concentrator or concentrators 54, the concentrator 54 in turn transmits the data to a connection point 56 and then to a server 58. Typically in a large installation the system uses a mesh network. At each stage of data transmission there will be a "handshake" between the transmitter and receiver, whether it is a liquid dispenser and concentrator, concentrator and concentrator, concentrator and connection point or connection point and server. A handshake confirms the data that is received and instructs the liquid dispenser to clear the information from the memory. Server 36 can be on-site or off-site.
    [0066] Consequently, here when designing the system for the use of a health care facility, for example, a hospital, there are a number of competing interests. Specifically, the system will require a plurality (100's or more likely 1000's) of self-powered electrical (battery) activation sensors that reliably need to transmit usage data wirelessly spreading around disorderly hospital buildings and data be transmitted via a GSM link (s) link (s) to the Internet for manipulating external data. Each sensor battery preferably has a long life (5+ years), is physically small (<a pack of cards) and preferably the system cost is low. It is preferable that the system does not interfere with medical equipment, be legal, and use radio licenses with free licenses.
    [0067] One solution is to use low power + low cost + minimal RF interference, this suggests a system along the lines of a Zigbee® / Z wave® type network architecture, using ultra low power transmitters (typically 0.1 mw) with minimal processing power. This provides low sensor hardware costs (currently approximately $ 5 / node) and requires an electrical outlet power supply network to be installed in each building to act as a "main structure" for communication and data processing. Knowledge of radio frequency propagation within buildings will lead those skilled in the art to select the lowest available frequency to maximize the variation of a given power output (reduces hardware costs of the 'mainframe' and improves reliable communications ) and consequently it will preferably choose between 400 and 450 MHz. This will provide a typical internal distance of 50 feet (15 m). Such a system is shown in figure 10 in 90. As an example, in an installation that needs around 4000 liquid dispensers, 200 concentrators are required as shown in figure 10,
    [0068] On the contrary, legislation allows for higher power transmissions (c. 500 mw) when using direct sequence spectrum spreading (DSSS) techniques at higher frequencies (868 - 930 MHz depending on location); this increases the distance (typically 330ft) but also cost (currently approximately $ 11 / node) and power consumption. However, in another modality shown in figure 11 in 96, it was determined that the reduction in the density of the “main structure” of the electricity supply network provides the savings that at least compensate for the increase in the sensor cost. The additional power requirements due to the 5,000-fold increase in transmission power are able to be significantly offset by more efficient firmware running on the sensor, enabled by the higher capacity microprocessor that is required to facilitate DSSS. For example, by increasing unit cost and output power, in this mode there is significantly reduced system cost and complexity without a noticeable penalty on battery life (a single battery mounted on the card that fits within the requirement of space preferably provides a useful life of 5 years +).
    [0069] In system 96, between approximately 20 and 40 concentrators are required with approximately 4000 liquid dispensers. The distance between the liquid dispenser and the concentrator can be up to 5,740 feet (1750 m). However within a health care facility, distances are more typically 330 feet (101 m) and in some cases longer than 330 feet (101 m) depending on the objects between the liquid dispenser and the concentrator. Those skilled in the art will appreciate that the maximum number of liquid dispensers per concentrator will be limited by the available network bandwidth and the number of bits per address. Since each liquid dispenser will generally have low activity on a network, more liquid dispensers can be supported than on networks in which all devices are continuously active.
    [0070] Implementations of concentrators using 8-bit addressing will be limited to connect 255 liquid dispensers, although other implementations with more bits per address may allow, eg. up to 10,000 liquid dispensers. Typically within a health care facility, each concentrator will receive data from about 200 liquid dispensers. In system 96 the transmission power is up to 1000 milliwatts. With the higher level data encryption system 96 it can be used and thereby provide a higher level of security than that provided by the lower frequency system. System 96 uses direct-sequence spreading transmission techniques that have a reduced rate of interference and are allowed to operate at higher powers when compared to the lower frequency system.
    [0071] Consequently the higher frequency system, in general between 850 and 950 MHz is advantageous over the lower frequency system in general between 400 and 450 MHz. The higher frequency system uses higher power and higher frequency that is opposite to conventional discrimination with data distribution systems of this type. Since the liquid dispenser uses more power, some preliminary processing can be carried out in the liquid dispenser.
    [0072] A group monitoring system for compliance of liquid dispenser use within a predetermined group of interest in a predetermined facility comprising the steps of: providing a plurality of liquid dispensers, providing a dispenser data collection system of liquid operably connected to each liquid dispenser, capable of providing information, information including a unique liquid dispenser identifier for each liquid dispenser, a number of liquid dispenser usage events that each liquid dispenser has been used; receive information from the data collection system and determine the predetermined group with which each liquid dispenser is associated; determining the number of hand hygiene events within the predetermined group within a predetermined period of time; determine a reference mark that corresponds to the opportunities for using the particular liquid dispenser for the predetermined group and particular for the predetermined period of time; calculate a particular liquid dispenser usage compliance index for the predetermined group and particular for the predetermined time period by dividing hand hygiene events for the predetermined group and the predetermined time period by a denominator, where the denominator is matches the reference mark. The number of hand hygiene events within a predetermined period of time equals a number of times that the liquid dispenser has been activated and that multiple activations within a predetermined period of activation are considered to be a single event of using a liquid dispenser. liquid. It is not uncommon that when someone uses a dispensing system more than merely activating it once, he activates the liquid dispenser multiple times. Consequently, in order to precisely determine the correct number of times the liquid dispenser has been used, the number of times the liquid dispenser is activated needs to be determined. However, where there are multiple activations within a predetermined activation period, this is considered to be a single liquid dispenser use event.
    [0073] The liquid dispenser usage compliance index can also include at least one of direct observation or inspection data. The data used in the liquid dispenser usage compliance index is weighted. The predetermined period of time can correspond to a shift of the predetermined group in the predetermined installation.
    [0074] The reference mark will probably vary depending on the predetermined installation, the type of unit in the installation, the time of day, and the day of the week. The denominator can also be the reference mark multiplied by the census data. The census data will be dependent on the interest group and can be, bed occupancy, patient days, visits to the patient, the number of bed hours for care or staff. The predetermined group can be a bed, a room, a ward, a unit, a floor or an installation.
    [0075] The liquid dispenser data collection system uses a system frequency between 400 and 450 MHz and a system frequency between 850 and 950 MHz. In one embodiment the liquid dispenser data collection system uses a system frequency between 850 and 950 MHz and has a transmission power of up to 1000 milliwatts. It further includes a plurality of concentrators for receiving data from a plurality of liquid dispensers and each concentrator receives data from one or more liquid dispensers and the distance between each liquid dispenser and its associated concentrator is generally no greater than 5,740 feet (1750 m). The data between the liquid dispenser and the concentrator is encrypted.
    [0076] The group monitoring system for collecting liquid dispenser usage data includes a plurality of liquid dispensers; a plurality of concentrators each capable of receiving data from one or more liquid dispensers; and that the distance between each liquid dispenser and its associated concentrator is typically no greater than 5,740 feet (1750 m) and data is transmitted at frequencies between 850 and 950 MHz.
