Filed:

Aug 1, 1988

Appl. No.:

7/226920

Inventors:

John V. Edwards - Surrey, GB
Frank M. Freeman - Lawrenceville NJ

Assignee:

E. R. Squibb & Sons, Inc. - Princeton NJ

International Classification:

A61F 544

US Classification:

604339

Abstract:

An ostomy system in which a third element is employed to absorb pressure when an ostomy pouch is mechanically secured to a body side portion adhesively secured to the body. The third element is a split-ring which can be secured around a body side rib coupling member. The split-ring includes an edge portion that fits in a groove in the outer rib wall and includes an angled outwardly projecting rim so that one or more fingers can be inserted between the rim and the body side surface while the pouch is coupled. Following coupling of the pouch, the split-ring can be removed to leave a two-piece ostomy system in place on the body.

Assignee:

E. R. Squibb - Princeton NJ

International Classification:

A61F 544

US Classification:

604332

Abstract:

An annular mounting member is bonded to the pouch wall to define a vent opening. The mounting member is made of material which is compatible with the pouch film and has a smooth exterior surface adapted to facilitate removable mounting of an adhesive coated element in alignment with the opening. The element may be a deodorizing filter assembly including a filter disk surrounded by an annular border member coated with pressure sensitive adhesive or a gas impermeable cover member designed to close the vent.

International Classification:

A61L 1900

US Classification:

128156

Abstract:

An occlusive wound dressing comprising a flexible closed cell polyurethane foam containing from about 5% to about 50% by weight of the foam of one or more water dispersible, water swellable, and/or water absorbing agents.

International Classification:

A61L 1500

US Classification:

128156

Abstract:

In accordance with the present invention an improved adhesive structure for adhesion of an article to a fluid-emitting wound and the surrounding normal skin is disclosed. The adhesive structure comprises a first contact region comprised of a fluid-interactive adhesive material which provides adhesion to the wound and surrounding normal skin; a second contact region comprised of the same or a different adhesive material, which provides adhesion betweeen the first region, or another region integral with the first region, and the article; and, an absorbent region comprised of an absorbent fibrous, fabric or foam material intermediate the first and second regions whereby enhanced cohesion between the first and second regions and between the second region and the article, under conditions of heavy fluid emission, is provided.
