    摘要： A non-adhesive absorbent wound dressing (10) is suitable for application about a jointed limb. The wound dressing (10) has a first portion (20) adapted to conform to and wrap around an upper part of the limb, a second portion (30) adapted to conform to and wrap around a lower part of the limb, and a hinge portion (40) between said first portion (20) and said second portion (30), said hinge portion (40) in use lying adjacent to the joint of the limb. The wound dressing (10) also comprises a porous wound contact sheet (80) and a substantially liquid-impermeable backing sheet (90), the wound contact sheet (80) and the backing sheet (90) being bounded (50) together at their periphery and along lines that define a plurality of pockets (60) in both the first portion (20) and the second portion (30), the pockets (60) containing absorbent material (70).

    摘要： A releasably adhesive laminate (1) comprises a structural layer (2) carrying on at least part of one side thereof a hydrophobic gel (4) and on at least part of the other side thereof a pressure-sensitive adhesive (3). The structural layer (2) is preferably a film of synthetic plastics material, eg polyurethane. The pressure-sensitive adhesive (3) is preferably an acrylic adhesive, and the hydrophobic gel (4) is preferably a silicone gel. The laminate (1) may be used as a skin contact component of a wound dressing or in numerous other applications.

    摘要： A device for collecting cellular material from a fluid sample comprises first and second chambers that are releasably connected and which define a fluid flow path from the first chamber to the second chamber. A porous membrane is between the chambers when they are connected to each other, in the fluid flow path. An absorbent body is positioned in close proximity to the downstream surface of the porous membrane, and a resilient member is arranged to urge the absorbent body towards the porous membrane. In use, a sample introduced into the first chamber contacts the upstream surface of the porous membrane and fluid is drawn through the porous membrane and is absorbed by the absorbent body. Cellular material is retained upon the upstream surface of the porous membrane. After separation of the chambers, the porous membrane can be removed from the device for analysis of the deposited cellular material.

    摘要： An apparatus (1) for negative pressure wound therapy comprises a source of reduced pressure (10) and first (22a) and second (26a) chambers, the first chamber being in fluid communication with the source of reduced pressure such that a negative pressure may be generated in the first chamber, the negative pressure being prevented from exceeding a predetermined value by way of a pressure release means (30), and the second chamber comprising means (28) for establishing a fluid connection with a wound. A valve (24) between the first and second chambers permits the negative pressure in the second chamber to increase in response to an increase in the negative pressure in the first chamber and prevents the negative pressure in the second chamber from dropping in response to a drop in the negative pressure in the first chamber.
