Abstract
Abstract This invention is a unique and improved shield to protect a limb which has been injured, is using an orthopedic device, bandage, or the like, or otherwise requires protection from water during bathing of patients or the like so concerned. The invention incorporates the use of a special sleeve to be slipped over a limb to be protected wherein the shield has an open end with a device suitable to encompass the limb and any bandage or other device associated with the limb and to allow easy engagement of the protective shield or sleeve, and wherein the device includes a flexible waterproof disk which will deform as necessary when being pulled over the limb and any appended involved. When fully in place, the flexible disk or the like seals about the shield and in combination with the sleeve or shield associated with it will protect the limb from any penetration of water.
