Abstract
The present invention relates to a transparent elastic compression bandage film composite for the treatment of venous diseases and tissue lesions, comprising a transparent film layer of 5-50 microns thickness, a medical adhesive coated on at least a portion of one surface of the film layer, which is preferably hypoallergenic, a first release liner for longitudinal detachment covering the adhesive film surface and, optionally, a second release liner for longitudinal detachment to serve as a carrier, wherein the effects of elasticity and of strong adhesion add to a compression quality superior to textile European standard compression media, in the main affecting superficial varicosities and long-term wearing.
Claims16
A film compression bandage composite using elastic forces combined with adhesive forces, for compression treatment of venous diseases and tissue lesions, comprising
- a. an elastic film with a modulus of elasticity of 5-400 N/mm2, when applying longitudinal expansions of 10-100%, and producing tensions of 1-40 N/mm2,
- b. a medical adhesive coated on at least a portion of a lower surface of the elastic film, which is pressure-sensitive and hypoallergenic, configured to adhere to an upper surface of the elastic film with an adhesive force of 0.12-2 N/25 mm, and configured to adhere to human skin with an adhesive force of 0.06-1 N/25 mm measured after 24 hours of wearing;
- and
- c. a first release liner covering the medical adhesive coating, for longitudinal removal, wherein the lower surface of the elastic film is coated homogenously and in an uninterrupted manner by the medical adhesive coating, and wherein the elastic film is transparent to ultrasonic imaging.
