Description

WEARABLE DEVICE FOR OSTOMY LEAKAGE DETECTION SYSTEM BACKGROUND [0001] This disclosure is related to a leakage detection system for medical devices, and more particularly to a wearable device for an ostomy leakage detection system. [0002] Known ostomy pouch systems can include 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. Commonly, such ostomy appliance may include, for example, an ostomy barrier of a one-piece pouch system which can be 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] However, 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, the extent of weakening in the seal. Thus, the user may not become aware of a weakened seal, and consequently, the ostomy effluent may leak through to an exterior of the ostomy appliance. An ostomy leakage detection system may be used to detect such a leak. Such ostomy leakage detection systems can include subsystems that comprise a wearable device for alerting a user of an ostomy pouch system to the presence of ostomy effluent (or leakage) under a hydrocolloid skin barrier. Such a wearable device can connect to electronic sensors on the ostomy system to acquire and processes leak data. However, connecting to and securing the wearable device may be difficult for some users. For example, the wearable device may need a locking mechanism for opening and closing the wearable device with one hand. [0004] Accordingly, it is desirable to provide an easy-to-use wearable device for ostomy leakage detection system.
