Abstract: A coupling for an ostomy bag is described. The coupling includes a pair of cylindrical elements which each have a headed pin attachment means mounted on a respective flange. An interdigitation of pins and heads secures the cylindrical elements to one another. One of the coupling elements is adhesively attached to a wearer, and the other coupling element has an ostomy bag attached to it. Thus, an ostomy bag may be readily and securely attached to a user through the use of the present invention.

Abstract: A tap for a drainage bag includes a rotatable valve which is adapted to be readily taken apart for cleaning. The valve includes a body, having a cylindrical recess formed therein, and a cylindrical valve member which fits into the cylindrical recess in the body. The body is secured to a flat flange of plastic, which flange is typically welded, or adhesively fixed, in a face-to-face manner to a wall of the bag. The construction method used to make the tap is particularly well suited to rapid mass-production methods of manufacture.

Abstract: A multi-layered dressing including a layer of curative and absorbant material which contacts the wound, an intermediate layer of deodorizing material, and an air and gas permeable outer flexible layer which secures the dressing to the body.

Abstract: A deodorizing bag which encloses an ostomy bag. The cover bag is formed of material containing activated carbon or has an area of its inner wall formed of such filtering material.

Abstract: An attachable and detachable filter for use with an ostomy bag includes a plastics housing member having two sections hinged together by an integral hinge and each section has a peripheral wall. One section has at least one aperture in the wall and the other section carries a sharp-pointed resilient-headed generally cylindrical stud which is a push fit through the aperture in the other to clamp the two sections together. There is a layer of gas filtering material within one or both of the housing sections.

Abstract: A valve device which permits an ostomate to selectively filter and vent gas from an ostomy appliance. The appliance comprises as a first coupling member a surgical dressing having an adhesive layer and a flange having an upstanding annular wall or projection. The annular wall has one or more openings leading to a filter compartment. The openings are controlled by valves operated by means of a push button at the outer edge of the filter compartment. The adhesive layer and the flange have an aperture so that the dressing can be attached to the body around the stoma. This first coupling member is employed in conjunction with a second coupling member which is an ostomy bag having a channel surrounding the stomal bag opening which sealingly engages the upstanding annular wall of the first coupling member.
