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.

Pouch with mounting member for removable adhesive filter

An annular mounting member is bonded to the pouch wall to define a vent opening. The mounting member is made of material which is compatable 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.

A dressing comprising a flexible backing member and a pressure sensitive adhesive layer. The adhesive layer comprises one or more polyisobutylenes, elastomers, and one or more moisture absorbing, moisture transmitting, water soluble and/or water swellable agents. A dispersion of the active ingredient in a medium compatible with the adhesive layer is laminated to the skin contacting surface.

Method of preparing adhesive dressings containing a pharmaceutically

A novel two-piece wound dressing, providing protection during dressing changes to the delicate healing skin directly surrounding the wound, is provided according to the present invention. The dressing comprises a baseplate having an adhesive surface for contacting surrounding skin, and has an aperture extending completely through it over which a wound pad of a desired wound dressing material can be placed. Means are also provided for attaching the wound pad to the baseplate.

Wound dressing system

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.

Ostomy system utilizing a split ring to engage a two element coupling

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.

Ostomy coupling having integral O-ring coupling

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.

Adhesive structure and products including same

A composite skin barrier including a first adhesive component which fits around the stoma, a coupling element, and a second adhesive component which is flexible, light, and has a degree of porosity. The second adhesive component contacts the skin at a distance from the stoma.

Skin barrier for use by ostomates

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. A pressure sensitive adhesive is applied or laminated to one surface of the foam in a discontinuous pattern. A polymeric film or skin is laminated or formed on the opposite surface of the foam.

Wound dressing

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. A pressure sensitive microporous adhesive is applied or laminated to one surface of the foam as a continuous layer. A polymeric film or skin is laminated or formed on the opposite surface of the foam.

The container has an elongated port section formed of a flexible cylindrical wall. A first tube member is lodged within the wall at a location spaced from the end thereof. A second tube member is forceably inserted within the first tube member, engaging a section of the wall therebetween. The engaged wall section may include a double wall thickness. One of the tube members is composed of substantially non-elastic material and the other is composed of relatively elastic material. The elastic member will deform so as to tightly seal the wall section. A detent may be present on one of the tube members to cooperate with a detent receiving recess on the other to enhance the strength of the seal. Any conventional drain valve or tubing can be connected to the protruding end of the second tube member.

Fluid container port connector mounting

This invention is directed to an occlusive dressing useful for treating skin lesions and a granular material capable of interacting with wound exudate. Wounds emitting a large amount of fluid can be treated by first packing with the granular material and then covering the wound with the occlusive dressing.

Method of treating wounds with granules and dressing

Medical grade pressure sensitive adhesive compositions comprising a homogeneous mixture of one or more polyisobutylenes or blends of one or more polyisobutylenes and butyl rubber, one or more styrene radial or block type copolymers, mineral oil, one or more water soluble hydrocolloid gums, and a tackifier. One or more water swellable cohesive strengthening agents, an antioxidant, and various other optional ingredients may be included within the adhesive composition.
