Abstract

A method for accelerometer input for an ostomy leakage detection system. The method may be applied to a wearable device that can obtain a leakage data, determine a leakage level based on the leakage data, obtain accelerometer data, detect a double tap input based on the accelerometer data, and silence a haptic feedback leak level alert output based on the double tap input. The leakage data may include a leakage detected on at least one ring of a sensing accessory. The leakage level can indicate information about the leakage detected. The haptic feedback leak level alert discreetly notifies a user about the leakage detected.

Description

METHOD FOR ACCELEROMETER INPUT FOR OSTOMY LEAKAGE DETECTION SYSTEM BACKGROUND [0001] The present disclosure pertains to a method for accelerometer input for an ostomy leakage detection system. [0002] An ostomy pouch system typically includes a pouch formed from opposing sidewalls defining an internal collection area, an inlet opening for receiving a stoma, and an ostomy appliance for attaching the pouch to a user. The ostomy appliance may include, for example, an ostomy barrier of a one-piece pouch system, which is attached to one of the pouch sidewalls proximate an inlet opening, or a faceplate for a two-piece pouch system configured to releasably engage a pouch, and a barrier ring. The ostomy appliance may include a skin barrier material for adhering to and sealing against user’s peristomal skin surrounding the stoma. [0003] The ostomy appliance may be susceptible to ostomy effluent leakage, and the seal formed between the skin barrier material and the user may weaken. Oftentimes, the user may be unaware of, or cannot easily assess, an extent of weakening in the seal. Thus, the user may not become aware of a weakened seal, and consequently, the ostomy effluent may cause skin health complications and may leak through to an exterior of the ostomy appliance. [0004] Leakage detection systems may include an electronic device that processes leak data, detects leakage in ostomy appliances, and notifies a user of detected leakage. However, the electronic device may be attached to a user, and it may be difficult for a user to discreetly input user input. For example, a user may want to check the leakage status of the ostomy appliance without accessing the electronic device. [0005] Accordingly, it is desirable to provide a method for discreetly inputting user input to an electronic device for an ostomy leakage detection system.
