    FIELD OF THE INVENTION
    [001] The present invention relates to a method and a mobile monitoring system for monitoring the use of an absorbent article. It also refers to a mobile device from such a monitoring system and a computer program to make the mobile device and the monitoring system perform the method. BACKGROUND OF THE INVENTION
    [002] Urinary and / or fecal incontinence causes many people to use various types of absorbent products, such as incontinence pads, diapers etc.
    [003] In their daily lives, people affected by incontinence are often anxious, fearing that people in their immediate vicinity may smell the urine or feces escaping absorbent products.
    [004] Absorbent products are generally able to absorb and retain a certain amount of urine and / or faeces, but replacing the absorbent product too late can cause odors to escape and be perceived by people in the immediate vicinity. For many people who suffer from incontinence, this is a major problem, often causing feelings of shame and humiliation and even withdrawal from social life and isolation.
    [005] There are several known devices for monitoring urination or defecation in order to allow the timely replacement of absorbent products.
    [006] For example, there are diapers including humidity sensors that can trigger an alarm if the number of discrete insults has reached a certain insult limit. Such a diaper is disclosed in US 2009/0062758 Al. Another incontinence management system for monitoring wetting in absorbent articles is disclosed in US 2011/0263952.
    [007] A monitoring system that uses sensors to detect the smell of urination or defecation for patients with dementia is disclosed in JP2007167264 A.
    [008] However, the known solutions for monitoring the use of absorbent articles often involve complex and expensive monitoring products and / or systems that are not easily available to the public. In addition, well-known monitoring systems are not discreet enough to be used by active and social people in their daily lives. DESCRIPTION OF THE INVENTION
    [009] It is an objective of the present invention to solve or at least alleviate one or more of the problems mentioned above.
    [0010] In particular, it is an objective of the present invention to provide cost efficient and readily available means for monitoring the use of absorbent products.
    [0011] Another objective of the invention is to provide means to prevent late replacement of absorbent products.
    [0012] Yet another objective of the invention is to provide means for monitoring the use of absorbent products that are discrete and can be used by people who suffer from incontinence, in any social situation.
    [0013] These and other objectives are achieved by a method to monitor the use of an absorbent product, such as an incontinence pad, or a diaper, used by a user. The method comprises the steps of: - detecting, by means of an odor sensing device capable of being transported by the user and configured to communicate with a user's mobile device, at least one chemical indicating the presence of urine and / or faeces in the product; - transmitting, from said odor sensing device to said mobile device, a signal indicative of said detection; - receiving, on said mobile device, said signal indicative of detection; and - providing, by means of said mobile device, information related to the product based on said signal.
    [0014] The objectives are also achieved by a mobile monitoring system to monitor the use of an absorbent product used by a user, comprising: - an odor sensing device capable of being carried by the user and configured to communicate with a mobile device ; and - a mobile device capable of providing product related information to the user, where the odor sensing device is configured to detect at least one chemical indicating the presence of urine and / or faeces in the product, and to transmit a signal indicative of said detection for the mobile device, the mobile device being configured to receive said signal and provide information related to the product based on said signal.
    [0015] By carrying the odor sensing device, for example, in a clothing pocket, the user can be notified via a mobile device, such as a conventional cell phone, that urination and / or defecation has occurred and that it may be desirable to change the absorbent product. The use of a small size odor sensor device and a conventional mobile device, such as a mobile phone. makes the mobile monitoring system according to the invention discreet and easy to use in everyday situations.
    [0016] The product related information here means the information related to the use of the absorbent product. The product related information can comprise any of, or any combination of: - an indication that product replacement is required; - an indication that urination and / or defecation has occurred and that it may be advisable to replace the product; - a recommendation to replace the product; - a recommendation to replace the product before a certain period of time; and - a recommendation to exchange the product for another absorbent product with a greater or lesser capacity than the product currently used.
    [0017] The content of the information related to the products and, in addition, also the way in which the information related to the product is provided to the user is determined by the mobile device based on the signal received from the odor sensor device.
    [0018] The odor sensor device comprises an odor sensor, such as a nanosensor or an electrochemical gas sensor. Preferably, the odor sensor is configured to detect concentrations of at least one chemical indicative of the presence of urine and / or faeces in the absorbent product which is well below concentrations perceived by humans. In this way, the user can be provided with information related to the product well before the odor of urine or faeces can be perceived by people in the user's surroundings.
    [0019] The odor sensor can be configured to detect any type of airborne molecules indicative of the presence of urine and / or faeces. Examples of chemical substances that are indicative of the presence of urine and are detectable by means of odor sensors of adequate size today are: ammonia, amines, sulfides and ketones. Examples of corresponding chemical substances indicative of the presence of faeces are: hydroxides, indole, eschatol, thiols (sulfer) and hydrogen sulphide.
    [0020] In addition, the odor sensing device comprises a communication unit for providing communication with the mobile device. Preferably, the communications unit of the odor sensing device and the mobile device are configured for wireless communication with each other. For this purpose, the communications unit of the odor sensing device can be configured for Bluetooth-based communication with the mobile device.
    [0021] In other embodiments, the odor sensing device is designed as a mobile device adapter capable of being detachably connected to the mobile device. For this purpose, the odor sensing device can comprise a connector for removable connection to a standard connector of a mobile phone, and the communications unit of the odor sensing device can be configured to communicate with the mobile phone via said connection. For example, the odor sensing device can be perceived as a mobile device adapter adapted for detachable connection to an iPhone or an iPad. The connector of the odor sensing device may in this case be a 30-pin male connector.
    [0022] When adapted for wireless communication with the mobile device, the odor sensor device is preferably designed to be carried in the user's clothing pocket, for example, a pants pocket. It can also comprise fastening means, such as a clip, allowing it to be attached to the wearer, for example, a belt, of the user. When made in the form of an adapter that is removably connected to a mobile phone, the odor sensing device is preferably dimensioned in such a way that the mobile phone and the odor sensing device can be carried in a user's clothing pocket when connected to each other, or in the case of cell phones, attachable to the user's belt.
    [0023] Preferably, the odor sensing device is configured to generate the signal for the mobile device depending on the concentration of at least one detected chemical, which means that the signal is indicative of the concentration of at least one detected chemical . The mobile device can in turn be configured to estimate the amount of urine and / or faeces present in the absorbent product based on the signal, and provide the product related information based on said estimate.
    [0024] Preferably, the method further comprises the steps of obtaining capacity information related to the capacity of the absorbent product, and providing the product related information based on both the signal received from the odor sensing device and the information of capacity. This allows the product-related information to be based on a comparison between the estimated value of urine and / or faeces present in the absorbent product and the product's capacity, which in turn allows the product-related information to understand well recommendations based on the need to replace the product. Preferably, product related information includes a recommendation to replace the absorbent product before the estimated amount of urine and / or faeces in the product exceeds the amount of urine and / or faeces that can be absorbed and / or retained by the product.
    [0025] For this purpose, the method may comprise the steps of determining a capacity parameter indicative of the amount of urine and / or faeces that can be absorbed by the product based on said capacity information, and an excretion parameter indicative of the amount of urine and / or faeces present in the absorbent product based on the signal received from the odor sensing device. The product related information is then provided based on a comparison between the capacity parameter and the excretion parameter. If the comparison shows that the quantity present in the product is close to the product's capacity, the product-related information may include a recommendation to replace the product as soon as possible. If, however, the quantity present in the product is well below the product's capacity, the product-related information may comprise an indication that no product replacement is currently required.
    [0026] According to an embodiment of the invention, the mobile device is configured to determine a limit value for the maximum concentration of at least one chemical based on the capacity information, and to compare the detected chemical concentration, as indicated by the signal received from the odor sensing device with the maximum limit value. If the maximum limit value is exceeded, the mobile device notifies the user that the absorbent product should be changed as soon as possible, and if the detected chemical concentration is well below that maximum limit value, the mobile device can warn the user of that no replacement is needed at this time.
    [0027] According to another embodiment of the invention, the mobile device is configured to determine a maximum number of urine and / or faeces insults that can be absorbed and / or retained by the absorbent product, based on the capacity information. In this embodiment, the mobile device is further configured to estimate the number of urine and / or faeces excreted by the user, based on the signal received from the odor sensing device. The product related information to be provided to the user can then be selected by the mobile device based on the comparison between the estimated number of said insults and said maximum number of insults.
    [0028] The number of insults excreted by the user can be estimated based on the concentration of at least one chemical detected. For this purpose, the mobile device can be configured to determine a plurality of concentration ranges of at least one chemical, each interval corresponding to a certain number of insults, and to determine how many insults the detected concentration corresponds to by determining which range the detected concentrations fall.
    [0029] The mobile device can also be configured to use the rate of change in the concentration of at least one chemical product detected to determine the number of insults excreted by the user. For example, it can be configured to compare the rate of change of the detected concentration as indicated by the signals received from the odor sensing device with an insult threshold, and assume that an insult has occurred when the insult threshold has been exceeded. By keeping track of the number of times the insult limit value has been exceeded, the mobile device can count the number of urine and / or fecal insults excreted by the user and compare it with the maximum number of insults indicated above.
    [0030] Preferably, the mobile device is further configured to provide for a future need to replace the absorbent product based on the detected concentration of at least one chemical, and to present information related to the product on the mobile device indicative of that future need. For example, the mobile device can be configured to display a point in time, before the product must be changed. In order to predict the future need to replace the product, the mobile device can be configured to determine a trend towards the detected concentration of at least one chemical based on the signals received from the odor sensing device, and to predict a point in the future when the concentration exceeds a maximum limit value. The upper limit value is preferably determined by the mobile device based on the capacity of the product, as discussed above.
    [0031] The mobile device can also be configured to determine a trend for the number of discrete insults excreted by the user based on the occurrence of detected insults, and to predict future insults based on this trend. The future need to replace the product can then be predicted by the mobile device by estimating when the number of insults excreted by the user will exceed the maximum number of insults that can be absorbed and / or retained by the product, said maximum number of insults can be determined from the capacity information.
    [0032] Capacity information related to the capacity of the absorbent product is normally used by the mobile device to determine a capacity parameter that can be compared with an excretion parameter indicative of the presence of urine and / or faeces in the absorbent product. As understood from the discussion above, the capacity parameter can be a maximum limit value for the concentration of at least one chemical detected by the odor sensing device, or a maximum number of discrete insults that can be absorbed and / or retained by the product. The excretion parameter can be the concentration of at least one chemical detected or an estimated number of urination and / or defecation insults by the user, estimated based on the magnitude or rate of change of that concentration.
    [0033] The capacity information obtained by the mobile device and used to determine the capacity parameter may comprise information related to the type of absorbent product, the level of absorption capacity of the absorbent product, and / or the size of the absorbent product. Capacity information can be obtained via the mobile device through user input or from a database of products stored on the mobile device or an application server to which the mobile device is connectable.
    [0034] The mobile device can be any mobile device, that is, a portable device, capable of communicating with the odor sensing device and capable of providing information related to the product to the user in the form of visual, audible and / or vibrators, such as a mobile phone, a personal digital assistant (PDA), a tablet computer or any other portable computing device. Preferably, the mobile device should be of a size that allows it to be carried in the user's clothing pocket, or in a case that can be attached to the user's belt.
    [0035] The method according to the invention is preferably implemented by computer and executed by the mobile monitoring system by executing a computer program stored on the mobile device. Preferably, this computer program is carried out in the form of an application that can be downloaded to a storage medium of the mobile device. By allowing the method to be carried out by running an application that can be downloaded on existing mobile devices, the method becomes readily available to anyone.
    [0036] When executed by the device, the computer program, therefore, causes the mobile device to perform a method that comprises the steps of: - receiving, from an odor-sensing device capable of being carried by the user, a signal indicating that the odor sensing device has detected at least one chemical substance indicative of urination and / or defecation by the user; and - provide product related information to the user based on said signal.
    [0037] In addition, the computer program can be configured to cause the mobile device or the odor sensing device to perform any additional method steps described above.
    [0038] The invention also provides a computer program product comprising a non-volatile memory for storing computer-readable instructions, wherein the aforementioned computer program is encoded in said non-volatile memory.
    [0039] In addition, the invention provides a mobile device for monitoring the use of an absorbent product used by a user. The mobile device comprises a processor, a communication unit for communicating with the odor sensing device and a storage medium for storing computer programs executable by said processor, said storage medium storing the aforementioned computer program.

    [0045] Figure 1 illustrates a mobile (1a) monitoring system, that is, portable to monitor the use of an absorbent product. The monitoring system (1a) comprises a mobile device (2) and an odor sensor device (3a), which cooperate to provide a user of the absorbent product with information related to the use of the product. The absorbent product referred to here is an absorbent personal hygiene article, including, but not limited to, male or female incontinence protectors, Intimate pads, diapers with tape fastener, pants diapers and belt diapers.
    [0046] The mobile device (2) is a mobile phone in the form that is often referred to as a smartphone, but it should be appreciated that the mobile device according to the invention can be any type of portable computing device, such as a personal digital assistant (PDA) or tablet computer, designed and configured as described below.
    [0047] The mobile device (2) comprises a processor (4), to process the data. The data to be processed can be received from the odor sensor device (3a), network nodes to which the mobile device (1) is communicatively connectable, or can be stored in a digital storage medium (5) of the mobile device said storage medium being accessible by the processor (4).
    [0048] The mobile device (2) further comprises a communication unit (6) for communicating with the odor sensing device (3a) through a wireless communication interface (7), such as a bluetooth interface. The communication unit (6) is preferably also configured to allow the mobile device (2) to communicate with application servers on one or more networks such as the Internet.
    [0049] The mobile device (2) is also seen as being provided with a screen (8) to display information to the user, and if performed in the form of a touch screen, also to receive information from the user in the form of user input. The mobile device (2) may also include other means for receiving user input, such as buttons, microphones, etc. In addition, the mobile device (2) has a loudspeaker (9) to emit sound signals to the user.
    [0050] The odor sensing device (3a) is dimensioned to be carried in a user's clothing pocket, and preferably to be carried in the pocket of a pair of pants or a skirt. The odor sensing device (3a) may further comprise fastening means (not shown), such as a clip, for attaching to the wearer's clothing, for example, to a belt.
    [0051] The odor sensor device (3a) comprises an odor sensor (10), indicated in broken lines, which comprises one or more gas inlets (11), through which the gas to be analyzed can enter the odor sensor odor. The odor sensor (10) is configured to detect at least one chemical in the air that indicates the presence of urine and / or faeces in the absorbent product. Preferably, the odor sensor (10) is configured to detect a plurality of chemicals in the air indicative of the presence of urine and / or faeces. To this end, the odor sensor (10) can comprise a plurality of sensor elements configured to detect different molecules. The odor sensor (10) can be configured to detect chemicals, including, but not limited to, ammonia, amines, sulfides and ketones, all indicative of the presence of urine, and hydroxide, indole, eschatol, thiols (sulfer) and hydrogen sulfide, all indicative of the presence of feces.
    [0052] The odor sensor (10) of the odor sensor device (3a) may include a porous silicon plate sensor, sometimes referred to as a nanosensor. For example, it can be a carbon nanotube-based sensor operated to monitor electrical changes in the sensor material of a nanotube. For example, when a nitrogen dioxide (NO2) molecule is present, it will remove an electron from the nanotube. which in turn makes the nanotube less conductive. If ammonia (NO3) is present, it reacts with water vapor and donates an electron to the carbon nanotube. making it more conductive. By treating the nanotube with various coating materials, it can be made sensitive to certain molecules and immune to others.
    [0053] According to another embodiment, the odor sensor (10) is an electrochemical gas sensor. In this type of sensor, the gas to be analyzed diffuses to the sensor through the back of a porous membrane of a working electrode where it is oxidized or reduced. This electrochemical reaction results in an electric current that passes through an external odor sensor circuit. In addition to measuring, amplifying and performing other signal processing functions, the external circuit maintains the sensor voltage between the working electrode and a counter electrode for a two-electrode cell, or between the working and reference electrodes for a cell of three electrodes. In the counter electrode an equal and opposite reaction occurs, such that, if the working electrode is an oxidation, then the counter electrode is a reduction.
    [0054] In addition, the odor sensor device (3a) comprises a communication unit (12), for communication with the mobile device (2). When the sensor (10) detects a chemical odor indicative of the presence of urine and / or faeces, it generates a signal that is transmitted to the mobile device (2) by the communications unit (12). Preferably, the odor sensor (10) is configured to generate a signal depending on the concentration of the detected substance and, consequently, a signal that is indicative of the concentration of the detected substance for the mobile device (2).
    [0055] Figure 2 illustrates a mobile monitoring system (1b) according to another embodiment of the invention.
    [0056] The monitoring system (1b) differs from the monitoring system (1) in Figure 1a mainly in that it comprises an odor sensing device (3b), which is designed as a mobile device adapter configured for removable connection with the mobile device (2). The removable connection is achieved through a connector (13) of the odor sensor device (3b), said connector (13) is adapted to a connection interface of the mobile device (2). In this embodiment, the connector (13) and, in addition, also the communication unit (12), may need to be adapted to the connection interface of the specific mobile device for which the odor sensor device (3b) is intended. The odor sensing device (3b) and the mobile device (2) are preferably dimensioned in such a way that both fit into a standard-sized pants pocket. However, the monitoring system (1b) can also be attached to the user's clothing. For example, it can be carried in a case adapted to be attached to a user's belt.
    [0057] With simultaneous reference to Figures 1 and 2, Figures 3A and 3B show examples of how the mobile monitoring system (1a) and (1b) and the respective components can be loaded by a user (14) in order to control duly use of an absorbent product (15), according to the method of the invention described below.
    [0058] It should be noted that some or all of the steps of the present method are performed by the mobile device (2) of the monitoring system (1a), (1b) through the execution of a computer program stored in the storage media ( 5).
    [0059] Preferably, this computer program is carried out in the form of an independent application, which means that no data needs to be received from application servers that reside on a network to which the mobile device (2) must be connected. However, the computer program can also be a client application for a distributed software solution that further comprises a server application that resides on an application server to which the mobile device is communicably connectable. In this case, some of the method steps described below can be performed by the application server by running the server application.
    [0060] In a preferred embodiment of the invention, the computer program stored on the mobile device (2) is carried out in the form of an application. An application, sometimes referred to as a Mobile Application or a Mobile Application, is a software application designed specifically to run on mobile devices, such as smartphones and tablet computers. The application is available for download on the storage medium (5) from a download server to which the mobile device (2) is connectable. The application can be adapted to a particular mobile operating system, such as iOS Apps, Google Android or Blackberry OS and distributed through popular application distribution platforms.
    [0061] It should therefore be understood that "the application" refers to the computer program stored on the storage device (5) of the mobile device (2). The application can be run by touching a special icon displayed on the screen (8) of the mobile device (2).
    [0062] Figures 4 to 5 are flowcharts that illustrate different realizations of the method of the invention for monitoring the use of an absorbent product. In the description of these flowcharts, reference will be made simultaneously to the drawings previously described. In the flowcharts of figures 4 and 5, the boxes drawn with dashed and dotted lines indicate steps of the method performed by the user (14), boxes drawn with dashed lines indicate steps of the method performed by the odor sensing device (3a), (3b) , and boxes drawn with continuous lines indicate steps of the method performed by the mobile device (2). The method steps performed by the mobile device (2) and the odor sensor device (3a), (3b) can be caused by the mobile device application (2).
    [0063] Figure 4 illustrates the basic principles of the inventive method.
    [0064] In a first step, (SI), the application is opened by the user (14) of the absorbent product (15).
    [0065] In a subsequent step (S3), the mobile device (2) is paired with the odor sensor device (3a), (3b) by means of a wired or wireless pairing procedure, according to the interface ( 7) communication between the mobile device (2) and the odor sensor device (3a), (3b). The odor sensing device (3a), (3b) is then placed in a position where the odor sensing device (3a), (3b) is able to detect chemicals in the air, emitted from the absorbent product (15) .
    [0066] In step (S4), the odor sensor device (3a), (3b) detects at least one chemical indicating the presence of urine and / or feces in the absorbent product (15).
    [0067] In step (35), the odor sensing device (3a), (3b) transmits a signal indicating the detection in step (S4) to the mobile device (2). The signal can be a single signal that is generated by the odor sensor of the device (3a), (3b), when the concentration of at least one chemical exceeds a predetermined limit value. Preferably, however, the odor sensing device (3a), (3b) is configured to repeatedly transmit signals indicative of the current concentration of at least one detected chemical to the mobile device (2). For this purpose, the odor sensing device (3a), (3b) can be configured to transmit concentration signals at certain time intervals. In other embodiments, the mobile device (2) can be configured to send an order for the current concentration of at least one chemical to the odor sensor device (3a), (3b), whereby the odor sensor device (3a), (3b) is configured to respond to the request and transmit the signal to the mobile device (2).
    [0068] In step (S6), the signal is received by the mobile device (2).
    [0069] In step (S7), the mobile device (2) provides product information related to the use of the absorbent product (15) to the user (14), based on the signal received from the odor sensor device (3a ), (3b).
    [0070] In embodiments in which the signal transmitted from the odor sensor device (3a), (3b) to the mobile device (2) indicates that the detected concentration of the chemical exceeds a predetermined limit value, the mobile device (2 ) can be configured to provide the product related information to the user (14) without further analysis of the received signal. For example, if the limit value is adjusted to a concentration close to the concentration at which the chemical can be perceived by humans, the mobile device (2) can be configured to simply provide information related to the product in a visual, audible and / or vibrating alarm indicating to the user (14) that the absorbent product (15) should be changed as soon as possible.
    [0071] In embodiments where the signal indicates the effective concentration of at least one detected chemical, the mobile device (2) can be configured to analyze the received concentration signal and adjust the content of the product-related information, and, additionally. also the way in which information related to the product is provided to the user (14), based on the concentration of the chemical.
    [0072] The information related to the product is preferably provided to the user (14) by means of visual, audible and / or vibratory signaling on the mobile device (2). Instead, or additionally, it can be provided on a communication device, such as another mobile device or a computer, with which the mobile device can communicate, for example, a user caregiver's communication device. In the latter scenario, information related to the product can be provided to the communication device, for example, in the form of a text message (SMS) or an email.
    [0073] Figure 5 illustrates a more detailed embodiment of the inventive method. Here the method is seen as comprising an additional step (S3) of obtaining capacity information related to the product's ability to absorb urine and / or faeces. This step must be performed before the detection of the chemical in step (S4)
    [0074] The capacity information may comprise any of, or any combination of, the type of absorbent product, level of absorbency of the absorbent product, and size of the absorbent product. Capacity information can be obtained through user input and / or receiving information from a server application that resides on an application server with which the mobile device (2) can communicate.
    [0075] In a preferred embodiment, the step (S3) of obtaining the capacity information comprises a first step of obtaining information about the type of absorbent product, that is, information telling the Application whether the absorbent product is a protector for incontinence, a diaper, etc. For this purpose, the Application is preferably configured to display a list of various types of products on the screen of the mobile device (2), and obtain the product type information, with the user (14) indicating the correct alternative in the type list of products. It can also understand a second stage in which the Application obtains information about the level and absorption capacity of the absorbent product (15). Many types of absorbent products, for example, incontinence pads, are available within a wide range of absorption levels, and the product's ability to absorb and retain liquid can vary considerably between different levels of absorption. Typically, the level of absorption capacity is the level of absorption capacity of the product on a scale of values, the level and scale of which are indicated on the packaging of the absorbent product. Preferably, the application is configured to display a scale of absorption levels corresponding to a scale of absorption levels presented on the packaging of the absorbent product, and to obtain the level of absorption capacity, when the user indicates the correct level of absorption in the scale shown.
    [0076] The application can also be configured to obtain capacity information automatically through the automatic identification of the absorbent product. The application can be configured to automatically identify the product using a camera and suitable image recognition software, an RFID reader or a mobile device barcode scanner (2), and to obtain the capacity information automatically from from a product database stored locally on the mobile device (2) or from a product database stored on the application server mentioned above. For this purpose, the absorbent product can be provided with means to facilitate its automatic identification, such as a bar code (for example, a QR code) or an RFID tag.
    [0077] After obtaining the capacity information in step (S3), the mobile device (2) determines a capacity parameter in a next step (S3a). The capacity parameter is indicative of the amount of urine and / or feces that can be absorbed by the product (14) and is determined by the mobile device (2) based on the capacity information obtained in step (S3).
    [0078] In one embodiment, the mobile device (2) is configured to determine a maximum limit value for the concentration of at least one chemical as the said capacity parameter. This realization will hereinafter be referred to as the concentration-capacity realization. Adjusting the maximum limit value based on the capacity information allows the mobile device (2) to set higher maximum limit values for absorbent products with high capacities, and lower maximum limit values for absorbent products with lower capacities. In this way, the mobile device (2) can give the user (14) reasoned recommendations regarding the need to replace the product. No matter the capacity of the product, the limit value for at least one chemical product is preferably set by the mobile device (2) to a value that is well below the concentration perceived by humans in the vicinity of the user (14).
    [0079] In another embodiment, the mobile device (2) can be configured to determine a maximum number of urine and / or faeces insults that can be absorbed by the absorbent product as said capacity parameter. This achievement will hereinafter be referred to as the performance of insult-ability.
    [0080] In still other embodiments, the mobile device (2) is configured to retrieve the capacity parameter from a database of the Application itself or from a database of a server application with which the Application can communicate, using one or more parameters to identify the product type, the absorbance of the product, and / or the size of the product, as input parameters of the database request.
    [0081] In step (S4), the detection procedure starts and the odor sensor device (3a), (3b) analyzes the gas entering the odor sensor (10) to detect one or more chemicals that are indicative the presence of urine and / or feces in the absorbent product (14).
    [0082] When at least one of these chemicals is detected, the odor sensor device (3a), (3b), in step (S5a), generates a signal that indicates the concentration of the detected substance and transmits the signal to the mobile device (two).
    [0083] In step (S6a), the mobile device (3) receives the signal from the odor sensor of the device (3a), (3b), and determines an excretion parameter indicative of the amount of urine and / or feces found present in the absorbent product (14), based on the concentration of the detected chemical substance, as indicated by the sign.
    [0084] In the concentration-capacity embodiment described above, the mobile device (2) can use the concentration of the chemical detected as an excretion parameter.
    [0085] In the insult-capacity embodiment described above, the mobile device (2) can be configured to estimate the number of urine and / or faeces insults by the user, based on the signal received from the odor sensing device, and use that number as an excretion parameter. The number of insults by the user can be estimated by the mobile device (2) by determining a plurality of concentration ranges of at least one chemical product detected by the device's odor sensor (3a), (3b), where each concentration interval corresponds to a certain number of insults. The number of insults by the user can then be estimated through the mobile device (2) by determining within which range is the variation in concentration indicated by the signal.
    [0086] To estimate the number of urine and / or faeces insults by the user, the mobile device can also be configured to use the rate of change in the concentration of at least one detected chemical. For example, it can be configured to determine the rate of change in concentration of a plurality of signals received from the odor sensing device at different points in time. The mobile device (2) can also be configured to compare the rate of change so determined with a limit value (the "insult limit value"), and assume that an insult has occurred if the determined rate of change exceeds the limit value of insult. By repeatedly performing these calculations and counting the number of times the insult limit value has been exceeded, the mobile device can count the number of urine and / or faeces insults by the user and use that number as an excretion parameter.
    [0087] In step (S6b), the mobile device (2) compares the capacity parameter determined in step (S3a) with the excretion parameter determined in step <S6a).
    [0088] In the concentration-capacity embodiment, this means that the maximum limit value for the concentration of the detected substance is compared with the current detected concentration of the chemical, as indicated by the device's odor sensor signal (3a) , (3b), and in the insult-capacity realization, this means that the maximum number of insults that can be absorbed by the product (14) is compared with the estimated number of insults by the user.
    [0089] In the last step (S7a), the mobile device (2) provides information related to the product to the user based on the result of the comparison made in step (S6b). At least the content of the product-related information, but preferably also the way in which the product-related information is provided to the user is selected by the mobile device (2) based on the comparison result.
    [0090] According to another embodiment of the invention, the method may involve predicting a future need to replace the absorbent product (15), and viewing information related to this future need on the mobile device (2). For this purpose, the mobile device (2) can be configured to determine a trend towards the detected concentration of at least one chemical from a plurality of signals received from the odor sensing device (3a), (3b), and predict a future point in time when the concentration exceeds a maximum limit value. The maximum limit value is preferably defined as corresponding to a concentration of the chemical, which is not perceptible by humans in the vicinity of the user (14). The maximum limit value can also be determined by the mobile device (2) based on the product's capacity as discussed above.
    [0091] The mobile device (2) can also be configured to determine a trend for the number of discrete insults of urine and / or faeces by the user based on the frequency of detected insults, and to predict future insults based on this trend. The future need to replace the product (14) can then be predicted by the mobile device (2) by estimation when the number of insults by the user (14) will exceed a maximum number of insults that can be absorbed and / or retained by the product (15), this maximum number of insults can be determined from the capacity information as also discussed above.
    [0092] The mobile device (2) can use the forecast of the future need to replace the absorbent product (15), in order to show recommendations regarding the use of the product (15) to the user (14). For example, the mobile device (2) may display a moment before the product (15) must be replaced to prevent the odor of urine and / or feces from being perceived by the user (14) and by people in the user's immediate surroundings, and / or the time when the absorbent product (15) will be saturated, which means that it will be unable to absorb further insults.
    [0093] For some absorbent products, it may be desirable to distinguish between urinary and faecal insults by the user (14). This is of particular interest if the absorbent product (15) is a product for absorbing urine and faeces, for example, a diaper. In this case, the mobile device (2) can be configured to obtain information on the indicative capacity of the product's ability to absorb and / or retain urine and feces, respectively. It can also be configured to estimate both the amount of urine and the amount of feces present in the absorbent product (15) based on the signals received from the odor sensor device (3a), (3b). For this purpose, the odor sensing device (3a), (3b) can be configured to distinguish between chemicals indicating urine and chemicals indicating feces.
    [0094] It should be appreciated, therefore, that the steps of the method described above, for example, the steps of determining and comparing parameters of capacity and excretion can be performed for chemicals indicative of the presence of urine and faeces individually.
