Abstract

Claims (19)

1. An ostomy system operable to inform an ostomate of an ostomy device condition useful in preventing leakage relative to the ostomy device, the ostomy system comprising:

a base plate comprising an adhesive layer on a proximal side of the base plate that is adapted to secure the base plate to skin of a user;

an electrode assembly coupled to the adhesive layer, the electrode assembly comprising a plurality of electrodes, an electrical connection part, and a sensing part;

a coupling part having a first end that is connected with the electrical connection part of the electrode assembly and a second end that is movable in a distal direction away from a distal side of the base plate; and

a monitor device adapted to electrically collect and transmit leakage data to the user, the monitor device provided with an opening sized to receive the second end of the coupling part;

wherein the electrode assembly is configured to sense ostomy data including moisture propagation in the adhesive layer,

wherein the monitor device, when connected to the coupling part, is configured to collect the ostomy data and inform the user of a future leakage condition.

2. The ostomy system of claim 1 , wherein the electrode assembly is disposed on a distal side of the adhesive layer.

3. The ostomy system of claim 2 , wherein adhesive layer includes a plurality of sensor point openings, each sensor point opening communicating with the sensing part of the plurality of electrodes.

4. The ostomy system of claim 1 , wherein the second end of the coupling part engages with the opening of the monitor device by a linear motion adapted to insert the second end of the coupling part into the opening of the monitor device.

5. The ostomy system of claim 1 , wherein the monitor device comprises a snap fastener adapted to clasp and engage with the second end of the coupling part.

6. The ostomy system of claim 1 , wherein the monitor device comprises a locking mechanism adapted to lock the second end of the coupling part within the opening of the monitor device.

7. The ostomy system of claim 1 , wherein the monitor device comprises a locking mechanism movable between a first locked position and a second opened position, where the locked position is adapted to lock the second end of the coupling part within the opening of the monitor device and the opened position allows cleaning inside of the opening of the monitor device.

8. The ostomy system of claim 1 , wherein the monitor device comprises a locking mechanism comprising a lock button that is movable in a first direction to close and engage the opening the monitor device onto the second end of the coupling part.

9. The ostomy system of claim 1 , wherein the coupling part comprises an indent feature and the monitor device comprises an element adapted engage the indent feature of the coupling part to secure the coupling part in the opening of the monitor device.

10. The ostomy system of claim 1 , wherein, when the monitor device is connected to the coupling part, a portion on the monitor device is positioned between the coupling part and the base plate.

11. The ostomy system of claim 1 , wherein the opening is formed in a peripheral rim of the monitor device.

12. The ostomy system of claim 1 , wherein the coupling part comprises an alignment feature adapted to prevent mechanical connection with the monitor device when the coupling part is misaligned with the opening of the monitor device.

13. The ostomy system of claim 1 , wherein each of the plurality of electrodes of the electrode assembly comprises an electrode part and a ground electrode, and the electrode part and the ground electrode combine to form a moisture sensor of the sensing part.
