Abstract: An integral hinged clip having two limbs. One limb is held by two opposed resilient catch portions of the other limb within a channel defined by said other limb. The catch portions effecting said holding in their normal undeformed positions. The clip is useful as a closure for a drainable ostomy pouch.

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 system is provided by which an ostomy bag can be securely coupled to an adhesive dressing that fits around the stoma and yet will permit the bag to be removed without disturbing the dressing. This system involves a first coupling member bonded to the dressing and a second coupling member bonded to the ostomy bag around the stomal opening. One coupling member consists of an upstanding rib or other projection which is dimensioned to sealingly engage an opening in the other coupling member.

Abstract: An ostomy bag formed by welding two sheets of plastic material substantially around their periphery. The rear wall of the bag includes means to attach the bag to the user and the peripheral seal is interrupted at one or more places along the top edge of the bag. Filtering material such as carbon cloth or a housing containing filtering material can be welded in place between the front and rear walls of the bag at the opening in the peripheral seal. In one preferred embodiment, the filter element comprises a mounting block sealed into the top peripheral edge and a cartridge containing filtering material which is inserted in the mounting block.

Abstract: A catheter retainer comprising a member of synthetic plastics material having a central hole wholly or partly defined by a pair of resilient catheter-gripping jaws, and a resilient catch member for holding the jaws in their relatively closed position. The catheter retainer is preferably an insert that snaps into a coupling member which is carried by a pad of adhesive dressing material.

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 ostomy bag having a drain valve at a lower region thereof. The valve is formed of a short flexible tube that can be bent or kinked over a support web and a stopper which can be pushed into the open end of the kinked tube.

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.
