摘要:
An absorbent wound dressing (1) comprising a polymeric foam layer (3) having a plurality of discrete zones (2) on at least one surface (4) of the foam layer, the material forming the zones being less swellable than the foam layer material.
摘要:
An adhesive dressing comprising a backing layer (12), a pressure sensitive adhesive (14) thereon and a support layer (22) attached to the non adhesive surface of the backing layer characterised in having an additional edge strip component (16) on the adhesive surface to aid adhesion of the dressing to the skin.
摘要:
The present invention relates to an absorbent wound dressing which comprises a layer of hydrophobic silicone gel (3) which is intended to lie against the wound surface when the dressing is worn, a layer of carrier material (2; 7) which carries the gel layer and affords the requisite strength thereto, and an absorbent body (5) which is placed on that side of the carrier material and gel layer which lie distal from the wound surface in use, wherein the carrier material and the gel layer have mutually coinciding penetrating perforations (4) at least within the region of the absorbent body. According to the invention, a fluid barrier layer (6) is provided on that side of the dressing which lies distal from the wound surface in use.
摘要:
A vented wound dressing is disclosed comprising a thin conformable sheet material (12) at least a portion of the surface area of which is intended for placement as a dressing over a wound, which portion carries a pressure-sensitive adhesive coating (14) on one surface thereof for adhering the dressing to skin, the coating being applied to provide repeating areas (16) of the sheet material containing no adhesive, at least a portion of the repeating areas of no adhesive having slits (18) extending through the thickness thereof to permit transfer or wound fluids through the sheet material unimpeded by presence of adhesive material which can clog the slits and thereby inhibit fluid transfer therethrough.
摘要:
The invention relates to an absorbent dressing comprising a breathable impermeable substrate (4) and an absorbent foam (2), which is particularly suitable for use in the care of chronic or acute wounds. The invention relates to a dressing comprising an absorbent foam (2) and a protective substrate (4) that is impermeable to fluids, but permeable to water vapour, said substrate being formed by assembling a film (4a) and an openwork reinforcement that is coated with an adhesive silicone gel (4b) without blocking the holes in the reinforcement. In addition, the dressing comprises a non-absorbent web (5) which is disposed between the absorbent foam (2) and the substrate (4), which adheres to the adhesive silicone gel coating on the reinforcement and which is secured to the absorbent foam (2).
摘要:
This invention is a thin film device (10) for medical applications such as a wound dressing including an occlusive layer (11) having an edge portion (12) about at least a portion of the thin film device (10), and a non-continuous, hydrocolloid containing polymeric support layer (14) overlying the edge portion of the occlusive layer (11).
摘要:
The present invention relates to a method of manufacturing a wound dressing. According to the invention, the upper surface of a perforated carrier material (2) is coated with a curable silicone mixture (3) and cold air is blown onto the underside of the coated carrier material. Heat is then applied to the silicone mixture until it has cured to a silicone gel. The invention also relates to an arrangement for carrying out the method, and also to a wound dressing manufactured in accordance with the method.
