Abstract
A removable protective cover to be fitted on the limb joints, such as the elbow and the heel of a patient. It forms a generally "L" shape interior with one portion fitted over the fore arm and a portion over the upper arm. It is made of lambskin, having the leather or skin side out receiving the abrasive action from the bed (or chair), in which the patient is confined, and the wool side in, in contact with the wearer's skin. It is secured in position by quick-detachable straps that can be easily manipulated by a semi-invalid. It is made in different sizes, for adults and children, and can be used on the heel as well as the elbow.
