Abstract [en]

INTRODUCTION

Effective ulcer management requires the wound to be in a moist but still breathable environment, to facilitate healing, absorb exudates and prevent maceration. One of the applicable methods to achieve this is the use of composite dressings. Most composite dressings are made of three layers to provide absorption and a bacterial barrier in a non- or semi-adherent cover. Various common textile materials such as cotton, polyester, polypropylene and cellulose can be used as different layers in those wound dressings. In addition to these established dressings, electrical stimulation therapy may be used in treating ulcers. It has been reported that electrical stimulation can reduce the area and depth of the wound in a shortened time compared to conventional treatment. In summary, encouraging wound healing results have been obtained both from using composite wound dressing and from applying of electrical stimulation. The aim of this study is to present a conceptual design based on a woven 3D structure that combines the composite wound dressing properties with electrical stimulation for pressure ulcers healing/management.

METHOD

In the suggested structure, different layers in X, Y and Z led were designed with different materials for different purposes.  The top layer consisting of a low-density web to provide a non-adherent layer combined with two textile electrodes made of conductive threads, the middle layer contributes pressure release and absorption of exudates, and the bottom layer next to the wound for moisture keeping while still allowing adequate ventilation.

Two key properties were addressed in the study: pressure release and the possibility to provide electrical stimulation of the wound. Simulation with COMSOL Multiphysics was used to study pressure distribution according to Hertz contact theory. The surface resistance of the electrodes were also studied using in-house designed four-point measurement probes.

RESULTS

The simulation results show the composite structure to exhibit good pressure release properties. Surface resistance testing proved that the textile electrodes have resistance in the magnitude of 102 indicating that textile electrodes can be used for electrical stimulation in ulcers healing.

The first results from this study demonstrate the feasibility to design a textile system combining established composite dressings solutions with means for electrical stimulation based on 3D weaving technique to be applied in pressure ulcer healing.
