     DETAILED DESCRIPTION 
     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. 
     The 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. 
     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 moisture propagation in the adhesive material provided for attaching the base plate to the skin surface of a user. Depending on the nature of the pattern of moisture propagation in the adhesive, the ostomy system and devices thereof enable providing information to the user about the type of failure, 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&#39;s stoma and/or skin surrounding the stoma, such as a peristomal skin area. 
     The ostomy appliance includes a base plate, such as a monolithic, one-piece base plate, e.g. integrated with a sensor assembly part, or a base plate and a separate sensor assembly part, such as a sensor assembly part to be subsequently applied to a base plate. For example, to allow an arbitrary base plate, such as a conventional base plate, to achieve the features as described herein. Features as described with respect to the base plate herein may be provided by a sensor assembly part to be applied to a base plate, e.g. by the user. A sensor assembly part may be adapted to adhere to an ostomy plate. 
     A disclosed method of attaching a base plate to a user&#39;s stoma and/or skin surrounding the stoma, such as the peristomal skin area, may comprise attaching a sensor assembly part to a base plate and attaching the base plate, e.g. together with the attached sensor assembly part, to the user&#39;s stoma and/or skin surrounding the stoma, such as the peristomal skin area. Alternatively, the method of attaching the base plate to the user&#39;s stoma and/or skin surrounding the stoma may comprise attaching the sensor assembly part to the user&#39;s stoma and/or skin surrounding the stoma and attaching the base plate to the user&#39;s stoma and/or skin surrounding the stoma above the attached sensor assembly part. 
     The base plate and/or the sensor assembly part may comprise a first adhesive layer, also denoted center adhesive layer. During use, the first adhesive layer adheres to the user&#39;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 may have a stomal opening, such as a first adhesive stomal opening, with a center point. 
     The first adhesive layer may be made of a first composition. The first composition may comprise one or more polyisobutenes and/or styrene-isoprene-styrene. The first composition may comprise one or more hydrocoloids.

The first composition may comprise one or more polybutenes, one or more styrene copolymers, one or more hydrocolloids, or any combination thereof. The combination of the adhesive properties of the polybutenes and the absorbing properties of the hydrocolloids renders the first composition suitable for use in ostomy appliances. The styrene copolymer may for example be a styrene-butadiene-styrene block copolymer or a styrene-isoprene-styrene block copolymer. Preferably, one or more styrene-isoprene-styrene (SIS) block type copolymers are employed. The amount of styrene block-copolymer may be from 5% to 20% of the total adhesive composition. The butene component is suitably a conjugated butadiene polymer selected from polybutadiene, polyisoprene. The polybutenes are preferably present in an amount of from 35-50% of the total adhesive composition. Preferably, the polybutene is polyisobutylene (PIB). Suitable hydrocolloids for incorporation in the first composition are selected from naturally occurring hydrocolloids, semisynthetic hydrocolloids and synthetic hydrocolloids. The first composition may comprise 20-60% hydrocolloids. A preferred hydrocolloid is carboxymethylcellulose (CMC). The first composition may optionally contain other components, such as fillers, tackifiers, plasticizers, and other additives.

The tertiary sensor point openings may comprise one or more tertiary first sensor point openings and one or more tertiary second sensor point openings, the tertiary first sensor point openings configured to overlap parts of an electrode and the tertiary second sensor point openings configured to overlap parts of another electrode different from the electrode at least partly overlapped by the tertiary first sensor point openings. 
     The first adhesive layer may have a substantially uniform thickness. The first adhesive layer may have a thickness in the range from 0.1 mm to 1.5 mm, e.g. in the range from 0.2 mm to 1.2 mm. 
     The first adhesive layer may have a primary thickness in a primary part of the first adhesive layer, e.g. in a primary region within a primary radial distance or in a primary radial distance range from the center point of the stomal opening. The primary thickness may be in the range from 0.2 mm to 1.5 mm. such as about 1.0 mm. The primary radial distance may be in the range from 20 mm to 50 mm, such as in the range from 25 mm to 35 mm, e.g. 30 mm. 
     The first adhesive layer may have a secondary thickness in a secondary part of the first adhesive layer, e.g. in a secondary region outside a secondary radial distance or in a secondary radial distance range from the center point of the stomal opening. The secondary thickness may be in the range from 0.2 mm to 1.0 mm, such as about 0.5 mm. The secondary radial distance may be in the range from 20 mm to 50 mm, such as in the range from 25 mm to 35 mm, e.g. 30 mm. 
     The base plate and/or the sensor assembly part may comprise a second layer. The second layer may be a second adhesive layer, also denoted rim adhesive layer. The second layer may have a second radial extension that is larger than a first radial extension of the first adhesive layer at least in a first angular range of the base plate and/or the sensor assembly part. Accordingly, a part of a proximal surface of the second layer may be configured for attachment to the skin surface of a user. The part of a proximal surface of the second layer configured for attachment to the skin surface of a user is also denoted the skin attachment surface of the second adhesive layer. The second layer may have a stomal opening, such as a second layer stomal opening and/or a second adhesive stomal opening, with a center point. 
     The second adhesive layer may be made of a second composition. The second composition may comprise one or more polyisobutenes and/or styrene-isoprene-styrene. The second composition may comprise one or more hydrocoloids. 
     The second composition may comprise one or more water soluble or water swellable hydrocolloids.

The second composition may comprise one or more polybutenes, one or more styrene copolymers, one or more hydrocolloids, or any combination thereof. The combination of the adhesive properties of the polybutenes and the absorbing properties of the hydrocolloids renders the second composition suitable for use in ostomy appliances. The styrene copolymer may for example be a styrene-butadiene-styrene block copolymer or a styrene-isoprene-styrene block copolymer. Preferably, one or more styrene-isoprene-styrene (SIS) block type copolymers are employed. The amount of styrene block-copolymer may be from 5% to 20% of the total adhesive composition. The butene component is suitably a conjugated butadiene polymer selected from polybutadiene, polyisoprene. The polybutenes are preferably present in an amount of from 35-50% of the total adhesive composition. Preferably, the polybutene is polyisobutylene (PIB). Suitable hydrocolloids for incorporation in the second composition are selected from naturally occurring hydrocolloids, semisynthetic hydrocolloids and synthetic hydrocolloids. The second composition may comprise 20-60% hydrocolloids. A preferred hydrocolloid is carboxymethylcellulose (CMC). The second composition may optionally contain other components, such as fillers, tackifiers, plasticizers, and other additives. 
     Different ratio of contents may change properties of the first and/or second adhesive layers. The second adhesive layer and the first adhesive layer may have different properties. The second adhesive layer (second composition) and the first adhesive layer (first composition) may have different ratios of polyisobutenes, styrene-isoprene-styrene, and/or hydrocolloids. For example, the second adhesive layer may provide a stronger attachment to the skin compared to attachment to the skin provided by the first adhesive layer. Alternatively or additionally, the second adhesive layer may be thinner than the first adhesive layer. Alternatively or additionally, the second adhesive layer may be less water and/or sweat absorbing than the first adhesive layer. Alternatively or additionally, the second adhesive layer may be less mouldable than the first adhesive layer. The second adhesive layer may provide a second barrier against leakage. 
     The second layer may have a substantially uniform thickness. The second layer may have a thickness in the range from 0.1 mm to 1.5 mm, e.g. in the range from 0.2 mm to 1.0 mm, such as 0.5 mm, 0.6 mm, or 0.7 mm.

     The base plate and/or the sensor assembly part may comprise a monitor interface. The monitor interface may be configured for electrically and/or mechanically connecting the ostomy appliance (base plate/sensor assembly part) to the monitor device. The monitor interface may be configured for wirelessly connecting the ostomy appliance (base plate/sensor assembly part) to the monitor device. Thus, the monitor interface of the base plate and/or the sensor assembly part may be configured to electrically and/or mechanically couple the ostomy appliance and the monitor device. 
     The monitor interface of the base plate and/or the sensor assembly part may comprise, e.g. as part of a first connector of the monitor interface, a coupling part for forming a mechanical connection, such as a releasable coupling between the monitor device and the base plate and/or the sensor assembly part.

Thus, the first adhesive layer may be protected or experience more evenly distributed mechanical stress from the terminal elements of the base plate and/or the sensor assembly part, 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 and/or the sensor assembly part. 
     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. 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 part, a centre part, and/or a proximal part. The distal part may be between the distal end and the centre part. The proximal part may be between the proximal end and the centre part. 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 be gold plated copper. 
     The base plate may comprise a coupling ring or other coupling member for coupling an ostomy pouch to the base plate (two-part ostomy appliance). The center point may be defined as a center of the coupling ring. 
     The base plate and/or the sensor assembly part may have a stomal opening, e.g. with a center point. The stomal opening of the base plate and/or the sensor assembly part may be formed collectively of stomal opening(s) of the layers of the base plate and/or the sensor assembly part, such as of the top layer, the first adhesive layer, the second layer and/or the sensor assembly part. The stomal opening(s) of the layers of the base plate and/or the sensor assembly part, such as of the top layer, the first adhesive layer, the second layer and/or the sensor assembly part may be aligned to form the stomal opening of the base plate and/or the sensor assembly part. The stomal opening may be a through-going passage of the base plate and/or the sensor assembly part. The stomal opening may be arranged substantially in the center of the base plate and/or the sensor assembly part. The stomal opening(s) of the layers of the base plate and/or the sensor assembly part may be arranged substantially in the center of the respective layer. The stomal opening may be configured to receive a stoma of the user and/or the stomal opening may be configured to allow output from the stoma to pass through the stomal opening an into an ostomy pouch attached to the base plate. For example, the stomal opening may be configured to allow passage of output from a proximal side of the base plate and/or sensor assembly part to a distal side of the base plate and/or sensor assembly part. The size and/or shape of the stomal opening may typically be adjusted by the user or nurse before application of the ostomy appliance to accommodate the user&#39;s stoma. In one or more exemplary base plates and/or sensor assembly parts, the user forms the stomal opening during preparation of the base plate for application. 
     The monitor device comprises a processor and one or more interfaces, such as a first interface and/or a second interface. The monitor device may comprise a memory for storing ostomy data. 
     In one or more exemplary monitor devices, the processor is configured to apply a processing scheme, the first interface is connected to the processor and the memory, and the first interface is configured for collecting ostomy data from the base plate and/or the sensor assembly part coupled to the first interface. The ostomy data may comprise one or more, such as all, of first ostomy data from a first electrode pair of the base plate and/or the sensor assembly part, second ostomy data from a second electrode pair of the base plate and/or the sensor assembly part, and third ostomy data from a third electrode pair of the base plate and/or the sensor assembly part.

Providing  1218  proximal terminal element bend(s)  276 B may be an integrated step in affixing  1208  the proximal parts  274 B and the respective connection parts  217 . For example, an affixing material  296 , e.g. solder or glue, such as an electrically conductive glue, may be added to the connection parts  217 , and in providing  1218  proximal terminal element bends  276 B, the proximal parts  274 B may be brought into contact with the affixing material  296 .

Providing  1220  distal terminal element bend(s) may be an integrated step in securing  1210  the distal part  274 A of each of the one or more terminal elements  272  to the coupling part  210 .

     A coupling part  210 , a top layer  208  and an electrode assembly  204  are positioned such that a distal side of the electrode assembly  204  is facing the coupling part  210 , and such that the top layer  208  is between the coupling part  210  and the electrode assembly  204 . A second adhesive layer (not shown) may be positioned between the top layer  208  and the electrode assembly  204 . 
     In  FIG.  13   a   , terminal elements  272  are inserted through the electrode assembly from the proximal side towards the distal side of the base plate  4  and/or the sensor assembly part  700 . The terminal elements  272  are straight pins, e.g. from a longer strand of material. 
     The terminal elements  272  may for example be gold plated copper. The terminal elements  272  have a distal end  272 A and a proximal end  272 B. The terminal elements  272  may be inserted by penetrating the electrode assembly  204  and the top layer  208  with the distal end  272 A of the terminal elements  272  from the proximal side to the distal side of the base plate  4  and/or the sensor assembly part  700 . A distal part  274 A of the terminal elements  272  are extending into a terminal interface region  270  defined by the coupling part  210 . The terminal elements  272  may be extending through respective connection parts of the electrodes of the electrode assembly  204 . Alternatively, the terminal elements  272  may be extending through the electrode assembly  204  without extending though electrodes or connection parts of electrodes, e.g. the terminal elements  272  may be extending through a support layer of the electrode assembly  204  without extending though electrodes or connection parts of electrodes. 
     The coupling part  210  comprises guide holes  278  for receiving terminal elements  272  being inserted through the coupling part  210  from the proximal side. The guide holes  278  may facilitate positioning of the terminal elements  272 .

The distal staple element  602  comprises curvatures such that upon movement of the terminal elements  272  in a distal direction, the distal end  272 A of the terminal elements  272  are guided in a direction perpendicular to the distal direction. Thereby, the terminal elements  272  are provided with distal terminal element bends  276 A. Thereby, the terminal elements  272  may be secured to the coupling part  210 . 
     The terminal elements  272  are provided with proximal terminal element bends  276 B, as shown in  FIG.  13   c   .

The proximal staple element  604  is configured to guide the proximal part  274 B of each of the terminal elements  272  in a direction perpendicular to the distal direction and to press the proximal part  274 B of each of the terminal elements  272  towards the coupling part  210 , such as in a distal direction. Thereby, the terminal elements  272  are provided with proximal terminal element bends  276 B. The distal staple element  602  provides a counter force. The distal part  274 A and the proximal part  274 B of each of the terminal elements  272  are pressed towards each other by the distal staple element  602  and the proximal staple element  604 , and the coupling part  210 , the top layer  208  and the electrode assembly  204  are clamped between the proximal parts  274 B and distal parts  274 A of the terminal elements  272 . 
     Although illustrated as separate steps, the distal terminal element bend  276 A and the proximal terminal element bend  276 B may be provided simultaneously or almost simultaneously, e.g. the distal staple element  602  and the proximal staple element  604  may be engaging simultaneously or almost simultaneously. Thereby, the process will proceed from the situation as illustrated in  FIG.  13   a    to the situation as illustrated in  FIG.  13     c.    
     In providing the terminal elements  272  with the proximal terminal bends  276 B the proximal parts  274 B may be brought into contact with connection parts of electrodes of the electrode assembly, such as to electrically connect the terminal elements  272  with respective electrodes, such as connection parts of the electrodes. Furthermore, in providing the terminal elements  272  with the proximal terminal bends  276 B the proximal parts  274 B are brought into contact with the affixing material  296 . Thereby, the proximal parts  274 B and the electrodes and/or the connection parts of the electrodes may be affixed, such as bonded, together.

The top layer  208  has a distal side facing the coupling part  210  and a proximal side facing the distal side of the electrode assembly  204 .
