Problems solved by technology

[0006] However, superabsorbent materials are often produced as a free-flowing powder, a problem associated with this material when used in wound dressings is that the powder can easily transfer from the dressing into the wound

Embodiment Construction

[0060] exist figure 1 and figure 2 , a first embodiment of a wound dressing according to the invention is shown, generally denoted 1 . The dressing 1 is generally in the form of a square and comprises a backing layer 11 of a microporous polyurethane film, to the central part of which an envelope comprising a sheet 13 of superabsorbent material is attached.

[0061] The wrapper consisted of a square wound-facing sheet of gel material 14 woven from a mixed alginate / Tencel yarn material and a sheet of dry mesh polyester material 15, the outer surface of which was bonded to the backing layer 11 by an acrylic adhesive. The gel material 14 and the dry web polyester material 15 are thermally bonded to each other at their edges. The sheet 13 of superabsorbent material comprises sodium polyacrylate polymer particles encapsulated between two layers of tissue paper carrier material. The sheet 13 of superabsorbent material is slightly smaller than the inner dimensions of the enclosure...

Abstract

An absorbent wound dressing (1) comprising a superabsorbent material (13) that is in fluid communication with the surface of a wound to which the dressing is applied when in use. The superabsorbent material (13) is enclosed in an envelope (14,15) having a wound-facing surface that is knitted or woven from a yarn comprising gelling fibres.

Description

technical field [0001] The present invention relates to absorbent wound dressings. Background technique [0002] Different types of wound dressings are required to meet different clinical needs. However, a common requirement for wound dressings is that they should be able to absorb wound exudate while maintaining a structure sufficient to enable them to be easily removed from the wound after use. If the wound dressing is not cleanly removed from the wound, the patient will suffer additional trauma. Also, if pieces of the dressing are left in the wound, it can inhibit healing. [0003] In addition to the need to maintain structural integrity, it is important for many applications that a wound dressing be able to absorb large quantities of fluid. During the healing process, wounds produce exudate. Exudate is absorbed by the dressing, keeping the wound clean and promoting healing. A determining factor in how often a dressing needs to be changed is how quickly the dressing ...
