Abstract
The present invention relates to a mechanical wound cleansing device comprising a carrier layer and an abrasive loop system arranged above the carrier layer, whereby the loop system is an intermeshed fiber system which is intermeshed above the carrier layer and/or a loop system comprising highly and softly abrasive loops. The present invention further relates to a method of producing said mechanical wound cleansing device. The present invention finally relates to the use of said wound cleansing device for the abrasive removal of and cleansing of wounds, especially for venous leg ulcers, diabetic foot ulcers (neuropathic and neuro-ischemic), arterial ulcers, mixed etiology ulcers, pressure ulcers or traumatic wounds.
Claims23
A wound cleansing device, comprising:
- a carrier layer and a loop system made from fibers, wherein the loop system is arranged on at least one side of the carrier layer and protrudes from the carrier layer,
- wherein the loop system is an intermeshed loop fiber system which is intermeshed within or below the carrier layer,
- wherein the loop system comprises highly abrasive loops and softly abrasive loops, and
- wherein the intermeshed loop fiber system comprises a stitchbonded structure,
- wherein the highly abrasive loops are made from core-twisted yarns having a monofilament core surrounded by filaments that are finer than the monofilament core, and
- wherein the wound cleansing device is structured to clean a wound.
A method for manufacturing the wound cleansing device according to comprising the following steps:
- (a) provision of a nonwoven;
- (b) generating the loop system arranged on the nonwoven of step (a) by using a stich bonding process containing a pile thread and a sewing thread;
- and
- (c) heating of the loop system generated in (b) to activate low melt fibers of the carrier layer.
