Restraining device for treating e.g. chronic venous disease, has film obtained by extrusion techniques with circular or plate patterns and made of polyethylene material, where thickness of film edges and homogeneity decrease pinch effect

摘要

The retainer has an oriented multilayer film with very low thickness and high resistance. The variable thickness and the homogeneity of the film decrease pinch effect of the edges of the film. The film is obtained by an extrusion technique with circular or plate patterns, and is made of polyethylene material. The length and the width of the film are variable and conform according to the needs. Each of a set of layers of the film is obtained from various additives such as colors, cutaneous protective substances, anti-odors, anti-sweats or anti-bacterial additives.
