Abstract
Abstract A therapeutic foot and leg protector comprises a rigid outer shell having a soft protective liner disposed therein. The protector is perforated in its heel portion to allow air to enter the shell and circulate about the heel of a patient. The shell is made with a built-up support section to raise the shell above the general level of the bed, so that none of the perforations in the heel become blocked. In other words, the support section will facilitate a freer circulation of air about the heel of the patient, to effect a more rapid healing of heel sores. The liner has straps that project through slots in the shell and wrap about the foot and leg of the patient. This provides for the integral securement of both the liner and shell to the leg, while allowing the liner to be a separate element. A built-up ridge section in the heel portion of the shell prevents the heel of the patient from coming into contact with the shell. This will possibly prevent injury to the heel of the patient or the blocking of the perforations in the heel portion of the shell.
