Abstract
An ostomy faceplate for a two-piece appliance is disclosed in which the coupling ring is partially recessed into the wafer of the faceplate. The wafer includes a hydrocolloid-containing adhesive layer that is provided with a recess that receives a portion of the coupling ring, thereby resulting in a faceplate of distinctively low profile and enhanced conformability.
Claims17
A faceplate for a two-piece ostomy appliance, said faceplate comprising a coupling ring for mechanically and detachably coupling said faceplate to a collection pouch and an adhesive wafer supporting said coupling ring for adhesively joining said faceplate to the peristomal skin surfaces of a patient;
- said wafer being generally planar and including a layer of hydrocolloid-containing adhesive skin barrier material;
- wherein the improvement comprises said wafer having a recess facing in the direction of said coupling ring and having at least one side surface generally normal to the plane of said wafer;
- said wafer also having a base surface extending along a plane below that of a surface of said wafer adjoining said recess;
- said coupling ring including a portion thereof received in said recess and secured to the said base surface of said recess beneath the plane of said adjoining surface.
A faceplate for two-piece ostomy appliance, said faceplate comprising the coupling ring for mechanically and detachably coupling said faceplate to a collection pouch and an adhesive wafer supporting said coupling ring for adhesively joining said faceplate to the peristomal skin surfaces of a patient;
- said wafer being generally planar and including a layer of hydrocolloidal-containing adhesive skin barrier material;
- said coupling ring including an annular connecting portion extending axially away from said wafer and a radially outwardly extending flange portion extending along the plane of said wafer;
- wherein the improvement comprises said wafer having a recess facing in the direction of said coupling ring and receiving the flange portion thereof;
- said wafer having a surface adjoining said recess that is flush with a surface of said flange facing away from said recess;
- and means securing said flange to said wafer within said recess.
