Claims (15)

  1. An ostomy system (1) comprising a monitor device (6), an ostomy appliance (2) configured to be placed on a skin surface of a user, and an accessory device (8), the accessory device (8) comprising: - a memory (401); - an interface (403) configured to communicate with the monitor device (6) of the ostomy system and to obtain monitor data from the monitor device coupled with the ostomy appliance, the interface further comprising a display (403a); and - a processor (402) operatively connected to the interface and to the memory; characterized in that the processor (402) is configured to: - obtain context data; - determine one or more future operating states of the ostomy appliance (2) based on the monitor data and the context data, wherein a future operating state is indicative of future adhesive performance of the ostomy appliance, and - wherein the interface (403, 403a) is configured to communicate the one or more future operating states.
  2. The ostomy system according to claim 1, wherein the interface is configured to communicate with a server device (10) via a network (12).
  3. The ostomy system according to any of claims 1-2, wherein the monitor data comprises sensor data obtained from one or more sensors (140) in the monitor device.
  4. The ostomy system according to any of claims 1-3, wherein the monitor device comprises ostomy data obtained from electrodes (216) of a base plate (4) of the ostomy appliance.
  5. The ostomy system according to any of claims 1-4, wherein the accessory device is configured to obtain context data from one or more user applications (405) installed on the accessory device and/or from the memory of the accessory device.
  6. The ostomy system according to any of claims 1-5, wherein context data comprises calendar data, location data, nutritional data, health data, activity data, and/or medicine intake data.
  7. The ostomy system according to any of claims 1-6, wherein context data is quantified with one or more context parameters associated with one or more adjustment coefficients.
  8. The ostomy system according to claim 7, wherein the one or more context parameters are associated with a function parameterized with the one or more adjustment coefficients.
  9. The ostomy system according to any of claims 7-8, wherein the accessory device maintains a local or remote database or lookup table associating a context parameter with a corresponding adjustment coefficient.
  10. The ostomy system according to any of claims 1-9, wherein to determine the one or more future operating states of the ostomy appliance based on the monitor data and the context data comprises to determine one or more current moisture pattern types based on the monitor data and to generate one or more future operating states based on the one or more current moisture pattern types and the context data.
  11. The ostomy system according to any of claims 1-10, wherein to determine a future operating state comprises to determine a future operating state from a set of operating states.
  12. The ostomy system according to claim 11, wherein to determine a future operating state comprises to select an operating state from a set of predefined operating states based on context data.
  13. The ostomy system according to claim 12, wherein the set of predefined operating states comprises at least three operating states.
  14. The ostomy system according to any of claims 1-13, wherein the processor is configured to determine a future operating states of the ostomy appliance if a change criterion is fulfilled, wherein the change criterion is based on context data and monitor data.
  15. The ostomy system according to any of claims 1-14, wherein the ostomy appliance comprises a base plate.

Description

The present disclosure relates to an ostomy system. In particular, the present disclosure relates to communicating a future operating state of a base plate of an ostomy appliance. Background art can be seen in US2013/324952. Document US 2017/340474 shows an ostomy system according to the preamble of claim 1.

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.
