  • Patent number: 6640810
    Abstract: A foot protector to be worn on the foot of a bedridden patient. The foot protector has a fabric body, a top opening for exposing an anterior portion of the patient's foot and lower leg, a strap for partially closing the top opening, a fastener for securing the strap, a bottom opening for exposing the heel, and a toe flap adjacent the top opening for alternately supporting and covering the toes. The foot protector also includes a generally wedge-shaped deformable block enclosed within the fabric body for supporting the calf of the patient. The block has a truncated peak forming a plateau for relieving an Achilles region of the patient's foot and a heel relief area. Further, two lower longitudinal edges of the block are chamfered to allow the foot to be rolled from side to side and to prevent the foot from completely flipping sideways.
