Abstract
A flexible urethane suspension sleeve for use in attaching a below the knee prosthesis to the remaining portion of the patient's limb. The sleeve has a generally tubular shape and includes a preflexed portion. A reinforced intermediate portion provides for abrasion resistance in the portion of the sleeve covering the socket "ears" and is disposed intermediate first and second reinforced end portions having different elasticities. A pair of non-compressive portions are disposed intermediate the reinforced intermediate portion and the reinforced end portions and provide for a non-compressive suction adhesion to the thigh of the user and the prosthesis.
Claims11
A prosthesis sleeve having generally tubular first and second end portions wherein said prosthesis sleeve comprises:
- a first reinforced end portion being fully circumferentially stretchable;
- an opposed second reinforced end portion of limited circumferential stretchability;
- an intermediate reinforced portion being circumferentially and axially stretchable, said intermediate portion disposed intermediate the first and second reinforced end portions;
- a first non-compressive portion disposed between the first reinforced end portion and the intermediate reinforced portion, said first non-compressive portion having an elongated anterior portion which achieves the preflexed configuration of the sleeve;
- a second non-compressive portion disposed between the second reinforced end portion and the intermediate reinforced portion, said second non-compressive portion having an elongated posterior portion which achieves the preflexed configuration of the sleeve;
- and each of said first and second non-compressive portions being free of reinforcement and consisting of a flexible material having the physical property of non-compressive suction adhesion to the surface of the skin and prosthesis surfaces and being selected from the group consisting of urethane and polyurethane.
A flexible prosthesis suspension sleeve having generally tubular first and second end portions and being configured for attaching a below the knee prosthesis to the limb of a person having a below the knee amputation, said prosthesis suspension sleeve comprising;
- a first reinforced end portion being fully circumferentially stretchable;
- an opposed second reinforced end portion of limited circumferential stretchability;
- an intermediate reinforced portion being circumferentially and axially stretchable, said intermediate portion disposed intermediate the first and second reinforced end portions;
- a first non-compressive portion disposed between the first reinforced end portion and the intermediate reinforced portion, said first non-compressive portion having an elongated anterior portion which achieves the preflexed configuration of the sleeve;
- a second non-compressive portion disposed between the second reinforced end portion and the intermediate reinforced portion, said second non-compressive portion having an elongated posterior portion which achieves the preflexed configuration of the sleeve;
- wherein the first non-compressive portion sectionally adheres to the limb and wherein the second non-compressive portion suctionally adheres to the prosthesis, and each of said first and second non-compressive portions being free of reinforcement and consisting of a flexible material having the physical property of non-compressive suction adhesion to the skin and prosthesis surfaces and being selected from the group consisting of urethane and polyurethane.
