This application is a U.S. 371 Patent Application of International Application No. PCT/DK2019/050059, filed 20 Feb. 2019, which claims priority to Denmark Provisional Application No. PA 2018 70109, filed 20 Feb. 2018, both of which are incorporated herein by reference in their entireties for all purposes.
The present disclosure relates to an ostomy system, devices thereof and method for monitoring an ostomy appliance. The ostomy appliance system comprises an ostomy appliance and an ostomy monitor device. In particular, the present disclosure relates to communicating a future operating state of an ostomy appliance, so as to e.g. change an ostomy appliance.
The accompanying drawings are included to provide a further understanding of embodiments and are incorporated into and a part of this specification. The drawings illustrate embodiments and together with the description serve to explain principles of embodiments. Other embodiments and many of the intended advantages of embodiments will be readily appreciated as they become better understood by reference to the following detailed description. The elements of the drawings are not necessarily to scale relative to each other. Like reference numerals designate corresponding similar parts.
Various exemplary embodiments and details are described hereinafter, with reference to the figures when relevant. It should be noted that the figures may or may not be drawn to scale and that elements of similar structures or functions are represented by like reference numerals throughout the figures. It should also be noted that the figures are only intended to facilitate the description of the embodiments. They are not intended as an exhaustive description of the invention or as a limitation on the scope of the invention. In addition, an illustrated embodiment needs not have all the aspects or advantages shown. An aspect or an advantage described in conjunction with a particular embodiment is not necessarily limited to that embodiment and can be practiced in any other embodiments even if not so illustrated, or if not so explicitly described.
Throughout this disclosure, the words “stoma” and “ostomy” are used to denote a surgically created opening bypassing the intestines or urinary tract system of a person. The words are used interchangeably, and no differentiated meaning is intended. The same applies for any words or phrases derived from these, e.g. “stomal”, “ostomies” etc. Also, the solid and liquid wastes emanating from the stoma may be referred to as both stomal “output,” “waste(s),” and “fluids” interchangeably. A subject having undergone ostomy surgery may be referred to as “ostomist” or “ostomate”—moreover, also as “patient” or “user”. However, in some cases “user” may also relate or refer to a health care professional (HCP), such as a surgeon or an ostomy care nurse or others. In those cases, it will either be explicitly stated, or be implicit from the context that the “user” is not the “patient” him- or herself.
In the following, whenever referring to proximal side or surface of a layer, an element, a device or part of a device, the referral is to the skin-facing side or surface, when a user wears the ostomy appliance. Likewise, whenever referring to the distal side or surface of a layer, an element, a device or part of a device, the referral is to the side or surface facing away from the skin, when a user wears the ostomy appliance. In other words, the proximal side or surface is the side or surface closest to the user, when the appliance is fitted on a user and the distal side is the opposite side or surface—the side or surface furthest away from the user in use.
The axial direction is defined as the direction of the stoma, when a user wears the appliance. Thus, the axial direction is generally perpendicular to the skin or abdominal surface of the user.
A radial direction is defined as perpendicular to the axial direction. In some sentences, the words “inner” and “outer” may be used. These qualifiers should generally be perceived with respect to the radial direction, such that a reference to an “outer” element means that the element is farther away from a centre portion of the ostomy appliance than an element referenced as “inner”. In addition, “innermost” should be interpreted as the portion of a component forming a centre of the component and/or being adjacent to the centre of the component. In analogy, “outermost” should be interpreted as a portion of a component forming an outer edge or outer contour of a component and/or being adjacent to that outer edge or outer contour.
The use of the word “substantially” as a qualifier to certain features or effects in this disclosure is intended to simply mean that any deviations are within tolerances that would normally be expected by the skilled person in the relevant field.
The use of the word “generally” as a qualifier to certain features or effects in this disclosure is intended to simply mean—for a structural feature: that a majority or major portion of such feature exhibits the characteristic in question, and—for a functional feature or an effect: that a majority of outcomes involving the characteristic provide the effect, but that exceptionally outcomes do no provide the effect.
The present disclosure relates to an ostomy system and devices thereof, such as an ostomy appliance, a base plate for an ostomy appliance, a monitor device, and optionally one or more accessory devices. Further, methods related to the ostomy system and devices thereof are disclosed. An accessory device (also referred to as an external device) may be a mobile phone or other handheld device. An accessory device may be a personal electronic device, e.g. a wearable, such as a watch or other wrist-worn electronic device. An accessory device may be a docking station. The docking station may be configured to electrically and/or mechanically couple the monitor device to the docking station. The docking station may be configured for charging the monitor device and/or configured for transferring data between the monitor device and the docking station. The ostomy system may comprise a server device. The server device may be operated and/or controlled by the ostomy appliance manufacturer and/or a service centre.
An ostomy system comprising an ostomy appliance and a monitor device, the ostomy appliance comprising a base plate is disclosed, wherein the monitor device is a monitor device as described herein.
The present disclosure provides an ostomy system and devices thereof, such as an ostomy appliance, a base plate for an ostomy appliance, a monitor device, and optionally one or more accessory devices which either alone or together facilitate reliable determination of the nature, severity and rapidness of erosion and/or swelling in the adhesive material provided for attaching the base plate to the skin surface of a user. Depending on the nature of the erosion/swelling pattern in the adhesive, the ostomy system and devices thereof enable providing information to the user about the operating state of the base plate, and in turn enable providing an indication to the user of the severity and thus the remaining time frame for replacing the ostomy appliance without experiencing severe leakage and/or skin damage.
The ostomy appliance comprises a base plate and an ostomy pouch (also referred to as an ostomy bag). The ostomy appliance may be a colostomy appliance, an ileostomy appliance or a urostomy appliance. The ostomy appliance may be a two-part ostomy appliance, i.e. the base plate and the ostomy pouch may be releasably coupled e.g. with a mechanical and/or an adhesive coupling, e.g. to allow that a plurality of ostomy pouches can be utilized (exchanged) with one base plate. Further, a two-part ostomy appliance may facilitate correct application of the base plate to skin, e.g. to an improved user sight of the stomal region. The ostomy appliance may be a one-part ostomy appliance, i.e. the base plate and the ostomy pouch may be fixedly attached to each other. The base plate is configured for coupling to a user's stoma and/or skin surrounding the stoma, such as a peristomal skin area.
A base plate for an ostomy appliance is disclosed, the base plate comprising a first adhesive layer with a proximal side configured for attachment of the base plate to the skin surface of a user, the first adhesive layer having a stomal opening with a center point; and a plurality of electrodes including a ground electrode, a first electrode, and a optionally a second electrode, the ground electrode comprising a ground connection part, the first electrode comprising a first connection part, and the second electrode comprising a second connection part, wherein the ground electrode forms a ground for the first electrode and/or the second electrode.
The base plate comprises a first adhesive layer. During use, the first adhesive layer adheres to the user's skin (peristomal area) and/or to additional seals, such as sealing paste, sealing tape and/or sealing ring. Thus, the first adhesive layer may be configured for attachment of the base plate to the skin surface of a user. The first adhesive layer has a stomal opening with a center point or is at least prepared for forming a stomal opening with a center point. A base plate with three electrodes having sensing parts with contact to the first adhesive layer allows for determining erosion/swelling properties or characteristics of the first adhesive layer and/or determining a degree of erosion and/or swelling of the first adhesive layer.
It is an advantage of the present disclosure that an optimum or improved use of an ostomy appliance is provided. In particular, the present disclosure facilitates that a base plate is not changed too early (leading to increased cell-stripping from the skin and increased risk of skin damage and further leading to increased costs and/or material waste) nor too late (leading to adhesive failure, leakage and/or skin damage from the aggressive output). Accordingly, the user or a health care professional is able to monitor and plan the use of the ostomy appliance.
Further, determination of erosion/swelling and classification of operating states of the ostomy appliance is useful in helping to reduce the risk of a user experiencing leakage from an ostomy appliance. Further, determination of degrees of erosion/swelling and classification of operating states of the ostomy appliance is further useful in helping reduce the risk of skin damage to a user. In particular, determination of degrees of erosion and/or swelling according to the present disclosure may help provide a clear distinction or differentiation between adhesive failure, leakage of output, which is harmful to the skin, and a sweating ostomate.
The present disclosure provides a simple, efficient, and easy-to-use ostomy appliance system with a high degree of comfort for a user.

The first intermediate element may cover or overlap terminal element(s) of the base plate when seen in the axial direction. Thus, the first adhesive layer may be protected or experience more evenly distributed mechanical stress from the terminal elements of the base plate, in turn reducing the risk of terminal elements penetrating or otherwise damaging the first adhesive layer. The first intermediate element may protect or mechanically and/or electrically shield the first adhesive layer from the terminal elements of the base plate.
A terminal element, such as the ground terminal element, the first terminal element, the second terminal element, the third terminal element, the fourth terminal element, the fifth terminal element and/or the sixth terminal element, may comprise a distal end and a proximal end.

In other words, the condition may be seen as a condition of the first adhesive layer.
The method comprises obtaining (e.g. retrieving and/or receiving) monitor data from the monitor device.
The monitor data may comprise ostomy data and/or parameter data. The monitor device is configured to process the ostomy data and/or parameter data based on the ostomy data to determine monitor data that is transmitted to the accessory device.

An operating state in the present disclosure is indicative of the dynamic internal state of the ostomy appliance (e.g. of the base plate of the ostomy appliance currently being worn by the user) related to adhesive performance of the ostomy appliance. Adhesive performance of the ostomy appliance may be related to an internal condition of the ostomy appliance (e.g. of the base plate of the ostomy appliance), such as an internal condition of an adhesive layer of the ostomy appliance. The adhesive performance, and thereby the operating state may be affected by several factors, such as humidity, temperature, misplacement of the ostomy appliance on the stoma, and/or malfunction of the ostomy appliance. The adhesive performance, and thereby the operating state may be related to misplacement of the ostomy appliance on the stoma, and/or malfunction of the ostomy appliance. The one or more factors alone or in combination impact the adhesive performance of the ostomy appliance. Accordingly, the operating state may be varying in time.
Thus, there is a need for communicating not only the current operating state, but also the future operating state so as to plan and prevent any undesired situation caused by e.g. the ostomy appliance leaking, e.g. during a planned activity.
Adhesive performance may be indicative of wear property, e.g. wear time and/or wear comfort.
In one or more exemplary methods, an operating state is configured to indicate whether the ostomy appliance is properly operational based on its adhesive performance (e.g. wear property of the base plate, e.g. wear time and/or wear comfort).
For example, the operating state may be indicative of the severity and/or imminence of a leakage (e.g. low, medium, acute). The operating state may comprise Z operating states, where Z is an integer. The operating state may comprise a first operating state, a second operating state, a third operating state (e.g. good, check, change in X time/NOW).

The current operating state may be seen as the operating state at the latest reception time of monitor data. The current operating state may be seen as the operating state at the determination time at a time indicated in monitor data (e.g. at a latest time indicated in the monitor data, e.g. at a latest period of time up to the latest time).
The method comprises determining a future operating state of the ostomy appliance (e.g. the future operating state of the base plate of the ostomy appliance) based on the monitor data and/or the current operating state. The future operating state is indicative of a future adhesive performance of the ostomy appliance (e.g. of the future adhesive performance of the base plate of the ostomy appliance). A future adhesive performance may be seen as a predictive adhesive performance, and/or an anticipated adhesive performance of the ostomy appliance in the future (e.g. the anticipated adhesive performance of the base plate of the ostomy appliance). The future operating state may be seen as an operating state that is anticipated to be reached after the current operating state. In other words, the future operating state may be seen as an operating state provided in advance of its occurrence (i.e. before it has happened). In one or more embodiments, the future operating state may be determined based on the current operating state by applying a applying a linear equation or a velocity factor as illustrated in
The future operating state may comprise at least one of: a wear time, a quality of adhesion, a moisture pattern representation.

The display of the first user interface screen comprising the first primary user interface object representing the current operating state and/or the first secondary user interface object representing the future operating state may be performed on the accessory device when the accessory device is a first operating mode (i.e. where the accessory device has an ostomy user application running) and/or a second operating mode (i.e. where the accessory device does not have an ostomy user application running).
A user interface object refers herein to a graphical representation of an object that is displayed on the display of the accessory device. The user interface object may be user-interactive, or selectable by a user input.

The visual output optionally includes graphics, text, icons, video, and any combination thereof (collectively termed “graphics”). For example, some or all of the visual output may be seen as corresponding to user-interface objects.
It is an advantage of the present disclosure that a user of an ostomy appliance or a health care professional is able to control the current and future operating state of the ostomy appliance and thereby plan the use of the ostomy appliance in his/her daily life. The disclosed methods enable an accessory device to foresee and predict a potential risk of future leakage by determining one or more current and future operating states based on monitor data. Thus, communication of the one or more current and future operating states of the ostomy appliance helps reducing the risk of a user experiencing leakage (e.g. faecal material leakage coming out from the ostomy appliance) from an ostomy appliance in a planned activity.
A reduction of the risk of leakage in turn helps in reducing risks of skin damage to a user (as it supports the prevention of leakage due to e.g. adhesive erosion, malfunctions and misplacement of the ostomy appliance on the stoma).
In particular, determination and communication of future operating state(s), and possibly with the current operating state, according to the present disclosure, is performed based on monitor data indicative of a condition of the ostomy appliance which may not be visible to the user (because it is under or within the base plate of the ostomy appliance).
Further, it is seen that the present disclosure provides a clear distinction or differentiation between the following events in the present and the future: adhesive failure, leakage (incl. partial leakage) of faecal material which is harmful to the skin, and a sweating ostomate.
The present disclosure provides an efficient, and readily accessible user interface for monitoring and prediction of performance of an ostomy appliance with an improved degree of comfort for a user while allowing to derive future operating states based on monitor data that is not accessible or visible by the user or the health care professional. In other words, the disclosed method allows to anticipate and indicate the dynamic internal of the ostomy appliance to a user, which supports the user in coordinating the use of the ostomy appliance with the planning of daily life activities.
The method may comprise detecting a first input selecting any of the first primary user interface object and secondary user interface object, and in response to detecting the first input, opening an ostomy user application, (e.g. an ostomy user application installed on the accessory device). For example, detection of first input that corresponds to selection any of the first primary user interface object and secondary user interface object triggers the launch and opening of the ostomy user application installed on the accessory device.
The method may comprise: in response to opening the ostomy user application, displaying a second user interface screen comprising a second primary user interface object representing the current operating state of the ostomy appliance and a second secondary user interface object representing the future operating state. The second primary user interface object representing the current operating state of the ostomy appliance may be derived from the first primary user interface object (e.g. may have a graphical representation derived from the graphical representation of the first primary user interface object (e.g. increased or decreased in size, resolution; providing more precise information regarding the respective operating states)).
In one or more exemplary methods, the method comprises displaying one or more user interface objects requesting the user to indicate whether the displayed current operating state (especially if indicative of leakage) corresponds to the operating state perceivable by the user (e.g. a “yes, there is a leakage” user interface object, and “no, all good”) so as to confirm the determination and display of the current operating state or so as to remedy an erroneous determination and display. The method may comprise detecting a user input (by selecting the user interface object or by receiving an utterance comprising: a “yes” or the word “leakage” or a “no” or the like) to determine whether the current operating state has been determined correctly.

The period of time may comprise K time periods, such as a first time period, a second time period, and/or a third time period. The memory may be configured to store the monitor data over a set of time periods comprising K time periods, wherein K is an integer. A time period may be expressed in terms of seconds, minutes, days, months, and/or years. A time period may relate to a time period of usage of the currently worn ostomy appliance (e.g. of the currently worn base plate). Additionally, or alternatively, the time period may relate to a time period of usage of similar ostomy appliances (e.g. base plates) previously worn by the user.
In one or more exemplary methods, determining the current operating state of the ostomy appliance (e.g. of the disclosed base plate) is based on the monitor data received over a period of time (e.g. over a set of time periods).
In one or more exemplary methods, determining the future operating state of the ostomy appliance (e.g. of the disclosed base plate) is based on the monitor data received over a period of time (e.g. over a set of time periods).
In one or more exemplary methods, determining the current operating state of the ostomy appliance is based on one or more previous operating states, such as based on one or more operating states previously determined by the accessory device (i.e. prior to the currently being determined operating state). The one or more operating states previously determined by the accessory device may relate the similar ostomy appliances as the one currently worn by the user. Optionally, one or more operating states previously determined by the accessory device may relate the different ostomy appliances as the one currently worn by the user, which have the same base plate as the one currently worn by the user.
In one or more exemplary methods, determining the future operating state of the ostomy appliance based on one or more previous operating states, such as based on one or more (future and/or current) operating states previously determined by the accessory device. A velocity factor may characterize a velocity of propagation of moisture through the first adhesive layer, as illustrated in

Determining the current operating state of the ostomy appliance and the future operating state of the ostomy appliance may be performed based on monitor data obtained for similar product types of ostomy appliances previously worn by the user. A product type may be associated with a velocity of propagation of moisture through the first adhesive layer, as illustrated in
Determining a current operating state of the ostomy appliance and a future operating state of the ostomy appliance may be based on a parameter characterizing a product type of the ostomy appliance (e.g. for similar product types of ostomy appliances previously worn by the user).
Determining a current operating state of the ostomy appliance and a future operating state of the ostomy appliance may be based on a base plate parameter characterizing a product type of the base plate (and optionally for base plate parameters characterizing (similar) product types of base plates previously worn by the user), a bag parameter characterizing a bag of the ostomy appliance (and optionally for bag parameters characterizing similar bags of ostomy appliances previously worn by the user), a ring parameter characterizing a ring type of the ostomy appliance (and optionally for ring parameters characterizing similar ring types of ostomy appliances previously worn by the user), a user attribute, wherein the user attribute comprises a user age, a user gender, a user metabolism, a user health condition, a user current activity level. A user attribute may also comprise a region or country of residence. A user metabolism may be characterized by a user metabolism parameter indicative of the general metabolism of a user. A user health condition may be characterized by a user health condition parameter indicative of a health condition of a user: current health condition, average health condition, health condition profile over time. For example, the health condition parameter may comprise a first health condition, and a second health condition.
A health condition I of a user may be indicative of the user being healthy, suffering from a permanent physical condition, suffering from a temporary physical condition. For example, if the health condition parameter indicates an inflammation, a future operating state may be determined to require an earlier change than if the health condition parameter indicates a healthy condition. For example, a user health condition may comprise an ostomy health condition such as ileostomy and/or colostomy. An ileostomist output may be more fluid than a colostomist output. A user health condition may be associated with a percentage of dilution of the output based on whether the user is an ileostomist or a colostomist.
A user activity level may be characterized by a user activity parameter indicative of an activity level of a user: current activity level, average activity level, activity level profile in time and/or in space. For example, the user activity parameter may comprise a first activity level, e.g. rest or sleep, and a second activity level, e.g. running or walking. An activity level of a user may be indicative of the user being stationary, sedentary, in motion, in exercising motion, in physical effort, resting or sleeping. A user activity parameter may comprise an activity level identifier and/or an activity level percentage. For example, if the user's activity level is high (e.g., when the user is running), a future operating state may be determined to require an earlier change than if the user is being less active. The reason being, inter alia, that the adhesion between the first adhesive layer and the skin surface of the user will likely degrade at a faster rate due to movement and, perhaps, increased perspiration when the user's activity level is high. Due to activity (e.g. sports, bending, movement), experimental results have shown that the operating state may be affected negatively by a reducing factor ranging from 2 to 10 compared to when the user has no or little activity (e.g. a sedentary user), For example, a wear time may be reduced by a factor of 2 to 10 due to an extensive activity. The disclosed accessory device is configured to select a factor ranging from 2 to 10 and to reduce (e.g. divide), by the selected factor, the current operating state when activity is detected, so as to determine the future operating state.

At a time of 5 h, curve 1300 shows that moisture is detected by the first electrode pair as the first parameter data crosses the upper voltage threshold value while curve 1302 shows that moisture is not detected by the second electrode pair as the second parameter data has not crossed the upper voltage threshold value. At this stage, it is determined that the ostomy appliance is in a first operating state.
At time around 15 h, curve 1302 shows that moisture is detected by the second electrode pair as the second parameter data crosses the upper voltage threshold value. At this stage, it is determined that the ostomy appliance is in a second operating state.
At time around 30 h, curve 1304 shows that moisture is detected by the third electrode pair as the third parameter data crosses the upper voltage threshold value. In an example where the curves 1306, 1308, 1310 had not dropped below corresponding thresholds, curve 1304 indicates that moisture has reached the third electrode pair, and the present disclosure enables determining that the ostomy appliance is in a third operating state.
Curve 1502 shows, as a function of time, first parameter data indicative of voltage measured by the first electrode pair of the base plate. Curve 1504 shows, as a function of time, second parameter data indicative of voltage measured by the second electrode pair of the base plate. Curve 1506 shows a diameter of the white ring as a function of time. The first parameter data shows a decrease in e.g. voltage measured by the first electrode pair over time. It is also seen that the voltage of the second electrode pair drops at a later time than when the first parameter data shows a decrease in e.g. voltage dropped. This correlates well with the diameter of the white ring which goes from around 25-26 mm when the first electrode pair is triggered (e.g. first parameter data shows a decrease) to 38 mm when the second electrode pair is triggered (second parameter data shows a decrease). This corresponds substantially to the location of the first electrode pair at twice the first radial distance R1, and of the second electrode pair at twice the second radial distance R2.
It is noted that various regions and countries have various routines and recommendations to support optimal use of an ostomy appliance. For example, in regions of Europe, it may be indicated to the user that an ostomy appliance with a base plate as disclosed herein is an optimal state (corresponding to a first operating state) when the radial thickness of the whitening ring is between 0-15 mm (for a user not in compliance with a preferred use), such as between 0-7 mm (for a user in compliance with a preferred use), such as between 0-5 mm (recommended by a nurse).
For example, in Europe, it may be indicated to the user that an ostomy appliance with a base plate as disclosed herein is in suboptimal state (corresponding to a second operating state) and thereby indicate a consideration to change the base plate when the radial thickness of the whitening ring is such as between 5-10 mm (recommended by a nurse), between 7 mm and 10 mm (for a user in compliance with a preferred use), and/or between 15 mm and 30 mm (for a user not in compliance with a preferred use).
For example, in Europe, it may be indicated to the user that an ostomy appliance with a base plate as disclosed herein is in a poor state (corresponding to a third operating state) and indicate a request to change the base plate when the radial thickness of the whitening ring is more than 10 mm (recommended by a nurse), such as more than 15 mm (for a user in compliance with a preferred use), such as more than 30 mm (for a user not in compliance with a preferred use).
For example, in other regions (e.g. America), it may be indicated to the user that an ostomy appliance with a base plate as disclosed herein is an optimal state (corresponding to a first operating state) when the radial thickness of the whitening ring is between 0-20 mm (for a user not in compliance with a preferred use), such as between 0-10 mm (for a user in compliance with a preferred use), such as between 0-10 mm (recommended by a nurse).
For example, in other regions (e.g. America), it may be indicated to the user that an ostomy appliance with a base plate as disclosed herein is in suboptimal state (corresponding to a second operating state) and thereby indicate a consideration to change the base plate when the radial thickness of the whitening ring is such as between 10 mm and 20 mm (recommended by a nurse), between 10 mm and 20 (for a user in compliance with a preferred use), and/or between 20 mm and 40 mm (for a user not in compliance with a preferred use).
For example, in other regions (e.g. America), it may be indicated to the user that an ostomy appliance with a base plate as disclosed herein is in a poor state (corresponding to a third operating state) and indicate a request to change the base plate when the radial thickness of the whitening ring is more than 20 mm (recommended by a nurse), such as more than 20 mm (for a user in compliance with a preferred use), such as more than 40 mm (for a user not in compliance with a preferred use).
The disclosed methods, ostomy appliances, monitor devices, and accessory devices allow to accommodate the regional preferences of user in their use of the ostomy appliance so as to adjust thresholds for the operating states to the regional preference or use.
Composition of the first adhesive layer of the base plate as disclosed herein in one or more embodiments is formulated to provide adhesion of the base plate to the skin surface of the user when the base plate is worn and to maintain a dry and healthy skin surface. Avoiding maceration of skin when occluding the skin with an adhesive is done by transporting sweat away from the skin and into the first adhesive layer by means of e.g. hydrocolloid types and adhesive (e.g. hydrocolloid adhesives) forming part of an absorbing element of the first adhesive layer.
For example, when the absorbing element is in contact with moisture, (e.g. water, sweat, urine or faeces), the absorbing element absorb the moisture. This reduces the adhesion of the first adhesive layer to the skin.
For example, the first adhesive layer goes from a dry adhesive state with acceptable adhesive performance (e.g. acceptable adhesion and cohesion) in to a wet adhesive state (e.g. reduced or non adhesion and low cohesion gel).
Curve 1602 of
Curve 1602 shows that the peel force applied to the first adhesive layer in a dry adhesive state is equal to Y1 when the peeling distance is less than X1. At X1, the peeling force drops as the peeling distance increases towards X5 and the end of the first adhesive layer.
Curve 1604 of
Curve 1604 shows that when the peeling distance is less than X2, the peel force applied to the first adhesive layer in a wet adhesive state is equal to Y2 which has much lower value than Y1. This shows that the adhesive performance of the first adhesive layer is reduced when the first adhesive layer is in a wet adhesive state. At X2, the peeling force drops as the peeling distance increases until the end of the first adhesive layer. It is noted that X2 is larger than X1, because the first adhesive layer in a wet adhesive state extends in volume, and thus in length due to the gelling of the components of the first adhesive layer.
The peel experiment illustrated in
Curve 1606 of
Curve 1606 shows that when the peeling distance is less than X3, the peel force applied to the first adhesive layer in a wet adhesive state is equal to Y3 which has lower value than Y1. This shows that the adhesive performance of the first adhesive layer is reduced when the first adhesive layer comprises a portion in a wet adhesive state. At X3, the peeling force drops as the peeling distance increases until the end of the first adhesive layer. It is noted that X3 corresponds to the length of the portion 1610A in dry adhesive state.

The present disclosure exploits the derivable velocities (e.g. velocity data) to determine a future operating state based on monitor data and/or current operating state.
The exemplary results of
Curve 2202 shows, as a function of time, first parameter data indicative of voltage measured by the first electrode pair of the base plate when a mixture of 0% semi-solid matter and 100% tap water is applied from the stomal opening of the base plate.
Curve 2204 shows, as a function of time, first parameter data indicative of voltage measured by the first electrode pair of the base plate when a mixture of 30% semi-solid matter and 70% tap water is applied. Curve 2204A shows, as a function of time, first parameter data indicative of voltage measured by the first electrode pair of the base plate when a mixture of 30% semi-solid matter and 70% tap water is applied.
Curve 2206 shows, as a function of time, first parameter data indicative of voltage measured by the first electrode pair of the base plate when a mixture of 30% semi-solid matter and 70% tap water is applied.
Curve 2208 shows, as a function of time, first parameter data indicative of voltage measured by the first electrode pair of the base plate when a mixture of 50% semi-solid matter and 50% tap water is applied.
Curve 2210 shows, as a function of time, first parameter data indicative of voltage measured by the first electrode pair of the base plate when a mixture of 100% semi-solid matter and 0% tap water is applied.
Curve 2212 shows, as a function of time, first parameter data indicative of voltage measured by the first electrode pair of the base plate when a mixture of 100% semi-solid matter and 0% tap water is applied.
It may be noted that the more diluted the semi-solid matter/output is the earlier the first electrode pair is triggered.
Curve 2214 shows a linear approximation relating the trigger times of the first electrode pair to the percentage of semi-solid matter, and thereby characterizes how the viscosity of the semi-solid matter affects the propagation of moisture in the first adhesive layer. The curve 2214 represents a linear equation with a coefficient of 10.6 with an approximation precision of 87% for the exemplary results. This supports a determination of a future operating state based one or more of: nutrition (type of food eaten by user, water intake, etc.), medication (e.g. vitamins/supplements, prescriptions, etc.), and health data (e.g. medical conditions of the user, diseases, ostomist, ileostomist, etc.).
It may be envisaged that a thin output may be detected based on the early triggering time of the first electrode pair and thereby the future operating state may be determined accordingly.
Due to activity (e.g. sports, bending, movement), experimental results have shown that the operating state may be affected negatively by a reducing factor ranging from 2 to 10 compared to when the user has no or little activity (e.g. a sedentary user), For example, a wear time may be reduced by a factor of 2 to 10 due to an extensive activity.
