Abstract: A three part ostomy coupling has a first part having a flange, a central chute and an array of space projections. A second part has a peripheral seal for engaging and surrounding the outer wall of the chute an outwardly projecting rim which can be snap fitted on the space projection. A third part is rotatable to effect a positive lock between the rim the projections, for example by deforming the projections inwardly.

Abstract: A device for wound management permits the application of an apertured pad to the wound and involves the provision of a protective compartment, optionally drained, whose interior is open to the wound and which is normally sealed closed but which can be opened if desired.

Abstract: For any ostomy appliance, a body-side ostomy member includes a medical grade adhesive pad and a coupling having one part captive to but telescopically slidable relative to another part to provide access for the fingers or thumb of a wearer beneath a lateral flange of the coupling, when the parts are spaced from one another.This allows an ostomy coupling to be secured together without applying undue pressure to the sensitive body area of the wearer.

Abstract: The ostomy appliance has two interengaging coupling elements. One of the elements is an annular plate which includes an engaging member formed by two ribs which diverge from each other to define a V-formation. One of the ribs has a stepped formation on its distal region. The other coupling element has an annular channel having cooperating formation adapted to engage the stepped formation, thereby connecting the coupling elements.

Abstract: A tube coupling adapted particularly for medical use includes three parts, namely a female tubular element 52, a male tubular element 50, and an intermediate ring 100 carrying at least one longitudinally extending latching arm 110. The ring is dimensioned to snap-fit into an external annular groove 90 on either the male or female element and the latching arm has an inwardly-extending hook portion 112 which can engage a flange 58 on the female or the male element as the case may be. This engagement holds these two elements together in an axial direction and allows them to rotate freely relative to one another.

Abstract: An ostomy bag has a filter attached to it by a series of plural sequentially peelable adhesive annuli.

Abstract: A bag having a flap valve beneath an opening at the top edge and a second valve including a longitudinally slidable valve member having a downwardly extending tube. When the slidable valve is in the open position the downwardly extending tube passes through the flap valve to provide sterile access to the liquid within the bag.

Abstract: A one-piece urostomy appliance has a drainage bag secured to an apertured flange which is in turn secured to an apertured adhesive pad. The body side of the apertured flange has a flexible skirt encircling the stoma aperture and located adjacent the radially inner boundary of the adhesive pad. The skirt is constructed and located to impede leakage of urine towards the adhesive pad.

Abstract: An improved ostomy appliance has two interengageable coupling elements, one of which (herein called the body side coupling element) is secured to a medical grade adhesive pad and the other side of which is secured to an ostomy bag. A flexible chute ring is interposed between the body side coupling element and the adhesive pad. The flexible chute ring is attached to a polymeric film surface of the pad at a first annular region and to the body side coupling element at a second annular region. The first annular region is located radially inwardly of the coupling element.

Abstract: An ostomy appliance comprises a body-attachable pad of skin-compatible adhesive material having a stomal orifice, and means whereby a plurality of ostomy bags can be attached in sequence to the pad by exposing a fresh region of adhesive each time it is desired to attach a clean ostomy bag.

Abstract: An integrally formed single piece loop ostomy appliance includes a central rod portion, a cross piece transverse to the rod portion at one end, and a displaceable end piece at the other end, displaceable between a first position which extends in the same general direction as the rod portion and a second position transverse to the rod portion. The end piece comprise a catch disposed to be in locking engagement with a recess in the rod portion when the end piece is moved to the second position. The end piece further comprises first and second spaced apart walls partially forming an aperture and adapted to be squeezed toward one another to release the catch from the recess. The loop ostomy appliance is preferably made of plastic, e.g. polypropylene.

Abstract: A gas filter suitable for an ostomy bag comprises a pad impregnated with a deodorizing agent (e.g., activated carbon) and made of any open cell plastic foam material which is laminated together with a first microporous membrane. A layer of water repellent material is applied on the surface of the first microporous membrane other than the surface to which the foam pad is attached. The layer is sufficiently thin so that gas flow through the microporous membrane is not blocked.

Abstract: A non-return valve assembly particularly for an incontinence device, includes a least three layers, the layers being secured together, the first layer being a sheet or film of perforated material, and the second layer is a sheet or film of material having cuts therein defining an array of flap valves. The third layer is a material having holes therein, each hole being in registry with an associated flap valve and being of a size to accommodate the flap of said valve. The flap valves may be arranged in a regular rectangular array and each flap of a valve is defined by three cuts in the sheet material, the cuts constituting three sides of a rectangle so that the flap of the valve can pivot out of the plane of the sheet material generally about a notional axis formed by the fourth side of the rectangle.

Abstract: A tap or valve comprising a first tube and a second tube with a flexible elastic coupling between said tubes to allow fluid passage between said tubes when said tubes are substantially coaxially aligned and to allow displacement of one of said tubes relative to the other in order to close said fluid passage. The tap or valve is primarily intended for use with wire drawings tubing or intravenous drip tubing. The tap or valve further comprises means for releasably locking the tap or valve in the closed position.

Abstract: A two part coupling for joining an ostomy bag to a pad or to a faceplate is characterized in that the two cooperating coupling parts are held together in a detachable manner by magnetic force.

Abstract: A tube closure device for closing a flexible tube has a first member having a tube portion for insertion into an end of the flexible tube, and a second member hinged to said first member and having means for securing the flexible tube to the second member. It also has a latch for releasably holding said first and second members in a hinged together "closed" position, and a plug for closing the tube portion of the first member when it is in its closed position.

Abstract: The tap or valve is made up of a first tube and a second tube which may be located about a common axis. Each of the tubes has a portion of its wall extending around only a part of its periphery, cut away. One of the tubes is rotatable between an "open position" in which the apertures wholly or partly overlap and a "closed position" in which the apertures are overlapped by a portion of the tube.
