Abstract: An ostomy coupling has two co-operating coupling elements. One is for attachment to a medical grade adhesive and the other is for attachment to an ostomy pouch. Each element is of close loop form and includes a tapering member extending around a stomal orifice. Each such member tapers in a radially outward direction and has a flat surface located in a plane at right angles to the coupling axis. The coupling also has a means of clamping which can be tightened onto the tapering members to hold them together. When held their respective flat surfaces are in face-to-face arrangement. Hence, two coupling elements can be held together and released without the application of any axial pressure forces or pulling forces to the wearer of the ostomy appliance.

To provide easy disengagement, the bag side ring has an integral flexible latching arm having a hook portion positioned to engage under a hook flange on the body side ring when the rings are coupled. The hook portion is disengagable from the hook flange by a lifting movement of the latching arm.

Abstract: A three part filter is provided for attachment to an ostomy bag. One part includes a synthetic plastics base member having a central aperture and one flat surface whereby the filter can be attached to the bag wall. There are two walls upstanding from the other side of the base member to define a channel. The inner wall defines a shallow recess. The second part is a pad of filtering medium. The third part is a lid member of synthetic plastics material, with apertures through its top wall; the lid being a snug push fit within the channel. With this arrangement the lid member is readily removable to allow replacement of the filter pad.

Abstract: A two-part ostomy coupling has a first part which is a flat annulus having inner and outer peripheral walls. With the annulus these walls define a shallow channel. The coupling has a second part formed by a second flat annulus with radially inner and outer rims formed by respective flexible peripheral elements of plastics material. The first and second parts are constructed so that the second part is a push fit into the shallow channel defined by the first part. An annular member having a flexible resilient strip extending inwardly from its radially inner edge and an element extending from its radially outer edge which can engage under a rim portion of the said outer peripheral wall. Alternatively, the second part may be an annular member having a flexible resilient strip extending outwardly from its radially outer edge and an element extending from its radially inner edge which can engage under a rim portion of the said inner peripheral wall.

Abstract: Apparatus for attaching a catheter to a bag includes a pair of coupling rings for trapping a part of the bag wall between them. A cutter having a blade of circular or closed loop form makes a cut in the trapped wall and an elastomeric member for gripping a catheter is connectable to the cutter or to one of the rings. The catheter is inserted in the elastomeric member and through the rings, the member serving as a gaiter.

Abstract: A faecal incontinence bag having flexible front and rear walls secured together around their periphery. The front wall has a hole therein for entry of matter discharged by the wearer. The hole is surrounded by an adhesive pad of skin-compatible water-resistant material secured to the external surface of the front wall surrounding the hole. The pad is generally heart-shaped so that when in position on the wearer the concave portion of the heart-shaped pad is towards the front of the wearer.

Abstract: A drainage tap can be readily fixed in a face-to-face manner to the wall of a plastics drainage bag and is easily operated by a user. The tap has a body and a valve member therein, and the latter is held within the body by engagement of an external rib on the valve member in a slot which extends into a flange of the body.

Abstract: An ostomy appliance intended for attachment to a peristomal area of a wearer includes a pad of medical-grade skin-attachable adhesive material, a first coupling element secured thereto, the element having a medically-extending flange attached to a surface of the pad and an upstanding rib of closed loop form constructed to couple with a couterpart (second) coupling element on a bag or pouch. An inner chute member is located radially within and adjacent to the first coupling element, the chute member having a substantially cylindrical wall covering the whole of the radially inner surface of the first coupling element. At one of its ends, the chute has a radially outwardly extending flange positioned so that it traps the chute member in position when the two coupling elements are coupled together.

Abstract: An attachment assembly is disclosed for attaching an article such as a wound cover or a prosthesis to human skin. The article attached may be, for example, a cover or dressing over a wound or a fistula or other lesion, it may be an eye patch or a breast prosthesis for use after masectomy or it may be a pouch to cover the genital region. The attachment assembly comprises a body-attachable pad of skin-compatible adhesive material and a series of double-sided adhesive layers thereon, which layers are constructed and arranged to be manually peeled off one-by-one when desired in order to expose a fresh adhesive surface to which the article is then attached.

Abstract: An ostomy appliance has four annular parts. The first part is attachable to the body of the wearer. It is also attachable to the third part by a second part which comprises a rotatable locking ring. The third part is attachable to the fourth part in a push fit manner and the ostomy bag is connected to the fourth part.

Abstract: A penile clamp has a flexible member for encircling the shaft of the penis. It can be tightened around the penis. The arrangement and construction of the flexible member is such that such tightening causes a localized pressure to be applied to a central portion of the underside of the penile shaft.

Abstract: A synthetic plastic bag for containing liquids, e.g., urine, has a plastic outlet tube. It is manufactured by a first step of seam welding the tube between two superposed bag walls. In a subsequent step, an encircling sleeve is slid over the tube to a position where it contains within it the portions of the bag walls on either side of the tube. Thirdly, this sleeve is compressed onto the tube by a crimping operation conducted with the crimping force applied in a direction substantially parallel to the plane in which the bag walls lie. The tube may be part of a tap or other outlet fitting such as a push-pull tap.
