Abstract
A device expecially suited for restaining the movements of the limb of a patient during a medical procedure is disclosed. The device includes a generally long rectangular flexible member which encircles the limb. The outside surface of this member is a Velcro loop pile. A strap having a Velcro hook fiber surface is attached at one of its ends to the encircling member. The strap is wrapped around the encircling member in the direction toward the end closest to which the strap is attached such that the Velcro hook fiber surface of the strap is brought into contact and locking engagement with the Velcro pile surface of the encircling member. The strap is routed through a small ring attached to the outside surface of the encircling member and proceeds to a support structure to which it is releasably attached by fastening means located at or near said end. Because of the locking engagement of the Velcro surfaces of the encircling member and the strap and the small size of the ring, the encircling member cannot be substantially tightened by a pulling force exerted on or by the encircled limb in a direction away from the support structure.
