Abstract
Active suctioning is used to evacuate a fabric, film or membrane for the purpose of securing orthotic, prosthetic, or other body worn articles, including sports-related articles. In contrast to the straps and tight-fitting approaches of existing devices, the inventive methods and apparatus provide for a slip-free seal to surrounding body parts, thereby simplifying construction, reducing weight, and enhancing comfort. The invention is applicable to any type of orthosis, prosthesis, foot wear, mitts, gloves, and so forth, including apparatus associated with the ankle and foot, knee, hip, back and neck, shoulder, elbow and hand.
Claims9
A body-worn implement, comprising:
- a flexible, continuous band adapted to completely encircle a calf portion of a human leg extending entirely through the band and terminating in an end portion which the band does not cover;
- the band having an inner surface that is initially spaced apart from the skin of a wearer and an outer surface with opposing outer side portions;
- a port in communication with the space between the inner surface of the band and the skin of the wearer, the port facilitating evacuation of the space so that the inner surface of the band makes intimate, slip-free contact with the skin;
- and
- a rigid structure coupled to the side portions of the band, the rigid structure including a portion that extends around and past the end portion of the leg, thereby transferring loads to the band and calf portion as opposed to the end portion of the leg during ambulation.
