    Abstract: A stoma adapter is described that is especially suited to a recessed stoma or a flush stoma. The stoma adapter effectively extends the discharge passage from the stoma, protects peristomal skin, and forms a bridge at the interface between the stoma and an ostomy appliance. The stoma adapter contains a substantially unobstructed discharge passage, at least for effluent flowing in a discharge direction. The stoma adapter includes a seal for sealing against the bowel wall. The stoma adapter has collapsing, expanding, flexible and reinforced designs.

    Abstract: A wound exudate management system includes a pump for generating negative pressure, a dressing for covering and protecting a wound of a user, a tube including an interior lumen, the tube disposed between the pump and the dressing such that the pump and the dressing are in fluid communication via the interior lumen. The dressing includes an adhesive layer for adhering the dressing adjacent the wound, a wound contact layer, a pressure dispersion layer, a plurality of layers of absorbent material disposed between the wound contact layer and the pressure dispersion layer, a backing layer having a first surface and a second surface, the first surface of the backing layer being adjacent, and in contact with, the pressure dispersion layer and the adhesive layer, and a flexible connector disposed on the second surface of the backing layer.

    Abstract: The body has a fluid inlet port for receiving pressurized fluid and a fluid outlet port connected to the retention balloon. A first passage connects the fluid inlet port and the fluid outlet port. A second passage in the body is connected to the balloon fluid return path and is at the pressure of the retention balloon. A valve prevents fluid flow through the first passage when actuated. The valve includes a pressure-responsive member movable to a position to obstruct fluid flow in response to fluid pressure in the second passage exceeding the predetermined level. Flexible means such as a membrane defines a normally open portion of the first fluid passage, which is closed by the moveable means bearing on the membrane when pressure exceeding the predetermined level actuates the valve.

    Abstract: The invention relates to a chemically modified cellulose based dressing particularly for use in the dressing of wounds but also for use as a packing material. Dressings according to the invention seek to mitigate the problems associated with shrinkage encountered with fibrous dressings made of gel-forming fibres and comprise a compressed body of chemically modified polysaccharide having a density of at least 0.08 g/cm3.
