New single-layer compression bandage system for chronic venous leg ulcers

Abstract

A new single-layer bandage system for the treatment of venous leg ulcers has been designed and developed at the University of Bolton. This three-dimensional (3D) knitted spacer fabric structure has been designed by making use of mathematical modelling and Laplace's law. The sustained graduated compression of the developed 3D knitted spacer bandages were tested and characterized, and compared with that of commercially available compression bandages. It was observed that the developed 3D single-layer bandage meets the ideal criteria stipulated for compression therapy. The laboratory results were verified by carrying out a pilot user study incorporating volunteers from different age groups. This article examines the insight into the design and development of the new 3D knitted spacer bandage, along with briefly discussing the issues of compression therapy systems intended for the treatment of venous leg ulcers.
