Embodiment Construction

[0020] exist figure 1 , a first preferred embodiment of a wound dressing 1 is shown schematically in cross-section. The wound dressing 1 comprises a wound pad 2 of absorbent material, covered on its outside by a backing layer 3 which extends beyond the periphery of the wound pad 2 . The backing layer 3 is covered on its inner side with an adhesive layer 4 at least in the region extending beyond the periphery of the wound pad.

[0021] The term "outer side" refers to the side of the part of the wound dressing facing away from the skin when the wound dressing is applied to a wound, and the term "inner side" refers to the side closer to the skin.

[0022] The backing layer 3 consists of a first plastic film 5 having holes 6 in it, and a second plastic film 7 joined to said first plastic film along the edges of the holes 6 . According to the invention, the second plastic film 7 is an electrically conductive plastic film. The term "conductive plastic film" refers to a plastic ma...

Abstract

The present invention relates to a wound dressing (1) including a wound pad (2) of absorbent material having a first side and a second side opposite thereto, a backing layer (3) covering the wound pad on the first side thereof an adhesive layer (4) for attaching the dressing to skin. According to the invention the backing layer (3) has at least one conductive region (7) and consists of plastic film.

Description

technical field [0001] The present invention relates to a wound dressing comprising a wound pad of absorbent material having a first side and a second side opposite said first side, covering said wound on said first side of said wound pad. A backing layer for the pad, and an adhesive layer for attaching the dressing to the skin. Background technique [0002] Electrical stimulation has been shown to promote wound healing and many devices for electrical stimulation of wounds are known in the prior art. In many devices, wires and the like drawn from the conductive sheet pass through the backing layer of the device. For such devices, it is difficult to obtain liquid tightness in the openings in the backing layer through which the wires pass. In other devices such as EP1589918 and EP0504715, the electrical contacts protrude from openings in the backing layer of the device. In both cases, an external barrier against external bacteria etc. and against exudates seeping through th...
