Description

METHOD FOR HAPTIC FEEDBACK FOR OSTOMY LEAKAGE DETECTION SYSTEM BACKGROUND [0001] This disclosure is related to an ostomy leakage detection system. More particularly, the present disclosure pertains to a method for haptic feedback 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 a 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. However, alerting the user of a leakage detection or information about the wearable device may be limited to sound or light notifications that may not be sufficiently discreet or adequate to notify a user. For example, the wearable device may discreetly alert user of a leakage detection by displaying a light, but that light may not be visible under the user’s clothing or it may be visible to others near the user. [0004] Accordingly, it is desirable to provide an improved ostomy detection system that provides discrete alerts to the user.
