Claims (14)

It is an ostomy bag,
two walls joined together around at least a portion of an edge of the ostomy bag, a first one of the two walls being configured to be placed facing the skin of a user; a second one of the two walls configured to face an opposite side of the user when the first wall faces the user's skin;
A seal disposed about the user's stoma at the first wall and configured to receive waste from the stoma and defining a discharge opening near a portion of the seam and defining a discharge opening. an opening spaced apart from a portion of the two walls that is not
a first portion located in, on or between one of said two walls of said ostomy bag and located adjacent said opening; and away from said opening and said discharge opening. a sensor layer having a second portion located proximate to and including a plurality of temperature sensors distributed over said first portion and said second portion; and a plurality of capacitance sensors distributed over said second portion; , including
The sensor layer comprises one or more antennas on an ostomy wafer and/or one on a user device configured to couple the first wall of the ostomy bag to the user's skin in use. An ostomy pouch further comprising one or more wireless communication antennas in electrical communication with the above processor. The ostomy bag according to claim 1, wherein the sensor layer is generally rectangular. The ostomy bag according to claim 1 or 2, wherein the sensor layer is smaller than the two walls. An ostomy bag according to any preceding claim, wherein the capacitive sensors are arranged in a pattern of lines, at least some of the lines forming non-90 degree angles with respect to each other. The ostomy bag according to any one of claims 1 to 4, wherein the temperature sensors are arranged in a matrix circuit. The ostomy bag according to any one of claims 1 to 5, wherein the plurality of capacitive sensors includes 24 capacitive sensors. The ostomy bag according to any one of claims 1 to 6, wherein the plurality of temperature sensors includes 48 temperature sensors. The ostomy bag according to any one of claims 1 to 7, wherein said discharge opening is closed by a Velcro® connector. 9. At least one of said plurality of capacitive sensors is located on a side of said sensor layer opposite said temperature sensor and the rest of said capacitive sensors and faces away from said user. Ostomy bag described in . A first portion of the Velcro connector includes a metal tape, and at least one of the plurality of capacitive sensors detects a change in capacitance when the first portion of the Velcro connector separates from its second portion. 10. The ostomy bag according to claim 9, configured to detect an ejection event at the ostomy bag. The ostomy bag includes multiple layers and the plurality of capacitive sensors facing away from the user when the first portion of the Velcro connector is attached to the second portion. allows direct contact between the metal tape and at least one of the plurality of capacitive sensors facing away from the user, 11. The ostomy bag according to claim 10, comprising one or more openings. A first direct or indirect contact between the metal tape and at least one of the plurality of capacitive sensors facing away from the user electronically activates the ostomy bag. 12. The ostomy bag according to claim 10 or 11, which is configured to: An ostomy bag according to any preceding claim, further comprising an accelerometer. Ostomy bag according to any of the preceding claims, further comprising a Bluetooth® module.
