Abstract

The present invention is an improved coupling for as ostomy bag system. In the improved coupling, an integral O-ring is included to improve the retention of the coupling as well as its seal by extending through the annular ring.

Claims

1. An improved coupling for an ostomy bag of the type comprised of a bag side flange and a body side flange, the improvement comprising:

(a) the body side flange including a relatively wide flange having an adhesive material for attachment to the body of the wearer and including an annular ring having a central aperture designed to surround a stoma and extending from said flange and the body side flange including an integral O-ring made of a resilient material which encircles the annular ring and is coupled thereto by a series of attachments formed as part of the O-ring and extending through said annular ring; and

(b) the bag side flange including an annular ring to lock onto the body side flange in a manner which compresses the O-ring to provide a resilient seal.

2. The coupling of claim 1 wherein said bag side annular ring includes a shoulder protruding toward said stoma opening and cooperates with the O-ring to couple said flanges together.

3. An improved coupling for an ostomy bag of the type comprised of a bag side flange and a body side flange, the improvement comprising:

(a) the body side flange including a relatively wide flange which carries adhesive material for attachment to the body of the wearer, an annular ring having a central aperture designed to surround a stoma and extending from said flange and a dual O-ring including an outer portion which encircles said ring and an inner portion on the inside of said ring, said inside and outside O-ring portions coupled together through said ring; and

(b) the bag side flange including inner and outer spaced apart annular rings adapted to lock onto the body side flange in a manner which compresses both portions of said O-ring to provide a resilient seal.

4. The coupling of claim 3 wherein said inner and outer annular rings each include shoulders which cooperate with the O-ring portions to couple said flanges together.
