    Application field
    [001] The present invention relates to the field of medical devices, more particularly to the field of infectious disease warning systems and contact isolation. Brief Description of the State of the Art
    [002] More than 90,000 Americans annually catch invasive, life-threatening infections from the drug-resistant Staphylococcus "superbug", Methicillin-resistant Staphylococcus aureus (MRSA), often in an institutional setting, such as a hospital; these infections reach the bloodstream or destroy the flesh and become deadly. MRSA-related hospitalizations have increased by as much as 119% over three years, according to some reports. Mortality rates reach an average of 1000 per month. Clostridium difficile (C. diff), which is a highly contagious bacterium that causes diarrhea, colitis, toxic megacolon and colonic perforations, can also spread in hospital settings through fecal contamination of objects and surfaces. Mortality rates from this have also increased dramatically in recent years. The fact that these and other organisms have mutated to become highly resistant to antibiotics, makes them difficult to eradicate, and thus an important initiative has been taken to prevent their spread. The principle of prevention is hygiene and contact isolation.
    [003] Other infectious agents are transmitted by air or droplet vectors and specific strategies are used to prevent their spread. Sometimes, the hospital must provide protective insulation for immuno-compromised patients.
    [004] Patients' rooms in the hospital are generally open to visitors, medical and paramedical staff and hospital employees, but when medically compromised patients occupy a hospital room, special precautions must be taken to prevent the transmission of disease to the patient or from the patient, following certain protocols that depend on the patient's condition.
    [005] It has been a problem for hospitals to alert visitors and staff to the precautions that should be taken regarding an individual patient in isolation. Due to the fact that hospitals are very busy places with many types of passive signs and other devices used for many purposes, it is not a rare occurrence that handwritten or even printed signs are ignored or accidentally not seen. In addition, the placement of the sign can be ambiguous if the doors or accesses are adjacent with little space between them.
    [006] A better, more active, however, inexpensive solution to this problem is necessary and it is an objective of the present invention to provide a device and a corresponding method to address this problem. Summary of the Invention
    [007] This objective and others that will become evident from the following disclosure and attached drawings, are achieved by the present invention which comprises in one aspect a system comprising a processor, memory, a speaker or a voice generator, and a set of programming instructions that work to allow an authorized user to select (A) a disease, condition or isolation type that corresponds to pre-programmed simulated voice alerts; or (B) one or more pre-programmed voice alerts; a room entry detector programmed to activate simulated voice alerts, the system being configured so that when entry to the room is detected, one or a combination of (A) one or more simulated voice alerts is emitted by the system corresponding to the selected disease, condition or type of isolation, or (B) one or more selected voice alerts.
    [008] Examples of voice alerts are “washing hands”, “wearing a gown”, “wearing gloves”, “wearing a mask”, “discarding a gown”, “using hand sanitizer”, “washing your hands with soap and water after removing protective clothing ”, and combinations of the aforementioned voice alerts. Additional examples of voice alerts that can be programmed into the system are listed in Table 1.
    [009] In another aspect, the invention comprises a method of alerting visitors and medical personnel of a patient's condition to a patient's room comprising placing such a system outside the patient's room and selecting a disease or pathological condition of the patient, type isolation or one or more specific voice alerts. The system is programmed so that when a person is detected entering the patient's room, one or a combination of voice alerts is issued by the voice generator or speaker. The private voice alerts issued by the voice generator or loudspeaker are those that are pre-programmed to be issued when a particular disease or condition of the patient or a type of isolation is selected, or are one or more of a plurality voice options that can be selected directly by an authorized user, for example, a nurse.
    [010] The system may comprise a portable unit that can be temporarily placed outside a patient's room, for example, on a door, door frame or wall near the entrance to the room.
    [011] The invention is an improvement over existing systems as it is much more unlikely that a visitor to a room that houses a patient with a contagious disease state, or an immune-depressed disease state, will unintentionally enter the room without proper precautions if the visitor is warned by an alarm system that issues voice alerts, especially if the voice alert is from a pre-programmed selectable set. Sophisticated aircraft cockpit systems have included, in recent years, voice alerts, especially those that simulate a female voice, for important events since it has been found that when pilots are very busy and in a hurry, such as hospital staff, they notice a female voice alert more readily than other types of alarms. Brief Description of Drawings
    [012] The description presented above, as well as other objectives, characteristics and advantages of the present invention, will be more fully understood with reference to the detailed description and the attached drawings. Fig. 1 is a front perspective view of the device according to the invention, showing a touch screen with a welcome message and a speaker. Fig. 2 is a front perspective view of the device according to the invention, showing a touch screen that indicates a selectable list of precaution types and a speaker. Fig. 3 is a front perspective view of the device according to the invention, showing a touch screen that indicates a selectable list of pathological states and a speaker. Fig. 4 is a front perspective view of a device according to the invention, showing a touch screen that indicates a selectable list of voice alerts and a speaker. Detailed Description of the Invention
    [013] A general reference is now made to Fig. 1, in which an embodiment of a system according to the invention, in which a box (11) that has a touch screen (12) features a welcome screen which has three selection modes “select by disease”, “select by type of isolation” and “select by individual voice alerts”. The box (11) includes a processor and memory, and a sound generator that is capable of generating voice simulations, and a speaker (13), as well as a touch screen (12). The housing (11) also includes a motion detector or proximity detector (15). The motion or proximity detector (15) can be adjusted for sensitivity and other factors using the touch screen (12) in an adjustment mode, for example. The motion detector (15) can be an intelligent detector so that it can distinguish between irrelevant events, such as a person passing through the room and a person actually entering the patient's room.
    [014] Fig. 2 illustrates the same device as it would appear on the screen when it is selected on the welcome screen, Select by Isolation Type
    [015] Fig.3 illustrates the device in Fig. 1 as it would appear on the screen when it is touched on the welcome screen, Select by Pathological State. An example of a set of voice alerts in an embodiment of the device includes: “washing your hands”, “wearing a gown”, “wearing gloves”, “wearing a mask”, “discarding a gown”, “using hand sanitizer”, “Washing hands with soap and water after removing protective clothing” and combinations of the aforementioned voice alerts.
    [016] Fig. 4 illustrates the device of claim 1 as it would appear on the screen when it is touched on the welcome screen, Select by Voice Alert.
    [017] Table 1 presents a more detailed list of possible voice alerts that can be pre-programmed in some other embodiments of the invention. TABLE 1 - List of Voice Alerts



    [018] Table 2 shows an example of a set of simulated voice alert announcements that are automatically made by the device when certain pathological conditions are selected by the nurse or other professional personnel and the motion detector detects a person entering the room. room. TABLE 2 - Voice Alerts by Pathological State


    [019] After selection of a pathological state, e. C. diff, the system automatically determines the selection of the appropriate voice alerts, but does not announce or show the disease or condition, e.g. C. diff, due to privacy concerns.
    [020] In some embodiments, an authorized user, such as a nurse, has an option to select an isolation type, in which case the preprogrammed voice alert corresponds to that type of isolation is issued by the device after detection of a person entering the patient's room. Table 3 lists some examples of possible voice alerts that correspond to such types of isolation. TABLE 3 - Voice Alerts by Isolation Type

    [021] The device of the invention can be autonomous or it can be part of another device or system. Programming can take place on the device, for example, through a nurse who selects alerts as someone would select from a menu of options in a dishwasher, clothes or dryer, or it can take place on a nursing console or even remotely through a hospital administrator who oversees many rooms. The set of instructions that make up programming can be in C ++ or any language in a variety of programming languages, and would normally be programmed in the processor. Simulated voice messages can be recorded by a person or can be synthesized from a dictionary of words or sounds.
    [022] A manual cancellation can be provided that allows a nurse or other frequent (and educated) visitors to the room to suppress the voice alert in a given situation or whenever necessary in case it becomes irritating.
    [023] In some embodiments, the device can be temporarily placed in a doorway, door or wall or near the entrance to a patient's room. The device can also be permanently placed on or inside a door frame, door or wall. The device will also include, in most embodiments, a motion detector (15) for detecting a visitor's approach to the patient's room. The motion detector (15) is preferably focused so that it has a narrow field of view, for example, a 15 degree field of view, and can be one of the passive infrared (PIR) type set to detect a person at 10 to 15 feet, or a conventional or specialized type laser or IR beam sensor. The device can be placed in a position and configured so that the motion detector (15) does not activate the alarm if a person passes but does not enter the room, or can include hardware and software to determine if a person is detected by the detector (15) of movement is the patient or a nurse for whom the alert is not necessary or is undesirable. The function of the device's motion detector (15) can be adjustable so that a greater or lesser sensitivity can be selected so that the alarm works when people enter the room, but not when they pass through the room.
    [024] The device can be programmed to allow the selection of one or more languages, for example, in certain institutions, announcements must be made in English and Spanish, while in other institutions, the announcements must be made in English and French or in another language commonly used.
    [025] The device may also include, in some embodiments, a touch pad and programming to request a password and to indicate a successful activation.
    [026] The device may also include a visual alert, such as flashing lights or a flashing signal, such as "contact isolation, speak to a nurse", which will light up when a visitor is detected entering the room.
    [027] The device can include a selection option on a tactile surface to choose between the modes "select voice alert message", "select disease or pathological condition" and "select the type of isolation".
    [028] The system and method of the invention are well adapted to solve a serious problem in hospitals and other institutions where patients may have diseases that require special precautions from those who enter the patient's room, to protect those who enter and the patient, in that the state of the art is to display a sign that indicates the precautions to be taken and in which such signs often go unnoticed. This invention provides an easy and quickly programmable system that allows the selection of a disease or state or type of isolation by an authorized person, in which the selection of the disease is not announced to those who enter the room and thus privacy requirements are met. , and where a voice announcement of precautions to be taken is calculated from the disease, condition or type of isolation, and where such a voice announcement is made automatically when the system detects a person entering the sick room.
    [029] Although the invention has been described in relation to a variety of embodiments, many additional variations and modifications will immediately become apparent to those skilled in the art. It is, therefore, the intention that the appended claims are interpreted as widely as possible in view of the prior art, to include all such variations and modifications.
