Device for preventing and treating foot and leg ulcers

Abstract

A foot is configured to map location and size of the ulcerations to treated at the bottom of the foot. First and intermediate insoles are made from including semi-compressed felt. A third sole serving as the base of the device is made from including, but not limited to EVA. A cavity with beveled edges in the first insole is configured to match the location and size of the ulcerations. The first insole, the intermediate insole and the foot with ulcerations are placed in a compression sock which is equipped with a zipper and is detachably attached on the top surface of the third sole. The cavity channels the drainage or extrude from the ulcerations to the intermediate in sole where it is absorbed. The zipper provides comfort to the patient to put on and take off the compression sock with any disturbance to the ulcerations .The compression sock enhances the blood flow in the foot which prompts efficient and quick healing of the ulcerations or chronic wounds.
