International Classification:

A61F 544

US Classification:

128295

Abstract:

A male urinary drainage device composed of a thin resilient external catheter or sheath and an adhesive sealant pad for holding the sheath in place and for producing an effective seal to prevent urine backup and leakage. The pad is formed of compressible, deformable, water-resistant, and elastic sealant material and includes a ring portion adapted to seal about the penis at or directly behind the glans thereof and at least one integral strap portion projecting radially from the ring portion and intended to extend along the penile shaft. The strap portion functions primarily to provide sheath retention, whereas the ring portion coacts with the retained sheath and with the penis to serve primarily as a barrier against fluid backup.

Assignee:

Hollister Incorporated - Libertyville IL

International Classification:

A61F 544

US Classification:

604339

Abstract:

An ostomy appliance including a collection pouch, an adhesive faceplate for adherence to a patient, and a coupling ring assembly detachably connecting the pouch and faceplate together. The coupling ring assembly comprises a pair of flexible plastic latching rings capable of being connected together by axially-applied forces and a soft, deformable, sealing ring interposed between, and axially compressed by, opposing wall portions of the latching rings.

International Classification:

A61M 3100
A61F 544
A61F 5448

US Classification:

604339

Abstract:

As ostomy appliance having a collection pouch and a flexible faceplate, the faceplate including an outer ring of thin, microporous sheet material and an inner ring of flexible, thermoplastic film impervious to gases and body fluids. The outer microporous ring surrounds the inner ring so that their adjacent margins overlap and are sealed to each other. The faceplate also includes a barrier ring secured to the inner marginal portion of the microporous ring on the side opposite from the attachment of the impervious inner ring. A fluid-impervious annular seal is provided between the impervious inner ring and the barrier ring at a location radially inwardly from the microporous ring, thereby securing the parts together and isolating the inner margin of the microporous ring from contact by stomal fluids. In preferred embodiments, the faceplate may include a relatively rigid, convex pressure ring and the impervious inner ring may extend a substantial distance radially inwardly from the seal with the inner margin of that ring secured to an outwardly extending thermoplastic web that in turn is connected to a faceplate coupling ring.
