Abstract

An orthopaedic gel pad assembly includes a layer of gel, with a backing layer behind it, an apertured pad extending around the layer of gel and a thin plastic film extending over the front surface of the gel. The plastic film controls the configuration of the front face of the gel, and the gel may be recessed, or indented, and may protrude forwardly out from the apertured pad. Stiff orthopaedic supports may be provided to back up the gel pad unit.

Claims

1. A reusable orthopaedic brace or support comprising:

a gel pad assembly including a layer of gel;

said gel pad assembly having an impervious thin front plastic film directly engaging and confining the gel in said gel pad assembly, for preventing contamination thereof and for preventing flow of said gel onto the user;

a backing layer extending across the rear of said gel, to confine said gel, and to prevent contamination thereof, said front plastic film being permanently bonded to said backing layer,

orthopaedic support means for holding said gel pad assembly against a portion of the anatomy of a user;

said plastic film defining the shape of the gel layer of said gel pad assembly and the thickness of the gel relative to said backing layer;

said gel pad assembly having a forwardly extending front surface which is formed of relatively flat gel material covered by said plastic film, and said assembly having other areas facing in the same direction as said front surface which are recessed back from said front surface;

said assembly permanently sealing the gel between the impervious front plastic film and the backing layer; and

a peripheral enclosing aperture pad secured to said backing layer and extending around and enclosing the sides of the gel, while the gel and said plastic film extend forward from a plane defined by the front surface of said aperture pad.

2. An orthopaedic brace or support assembly as defined in claim 1 wherein said backing layer is formed of a sheet of foam rubber.

3. A reusable ankle brace for insertion into a shoe for immobilizing the ankle against inversion and eversion while permitting planter-flexion and dorsi-flexion, comprising:

a pair of stiff side supports for fitting about the lower leg on both sides;

said side supports having a configuration to encompass both sides of the ankle, with the lower end of the side supports for insertion into the sides of the shoe;

a pair of liner members including a layer of dense gel for conforming to the shape of the ankle and for providing a resilient support against the ankle;

each said liner member including an apertured front pad having a patterned opening, an impervious thin film, a resilient backing pad, a semi-solid gel layer enclosed between said backing pad and said thin film, adhesive means for holding said thin film, said front pad, and said backing pad firmly and permanently together with said gel layer permanently enclosed between said thin film and said backing layer;

means for securing each said liner member to each said side support wall; and

means for securing said side supports to firmly encase the ankle, said means including a counter strap extending between said side supports at a position just above the heel, said means also including a U-shaped stirrup member for providing a tighter grip about the lower portion of the leg;

said means also including at least one strap extending between said side supports for firmly encasing and supporting the top and middle portion of the leg.

4. An apparatus as defined in claim 3 wherein said front pad and said backing pad each include a layer of foam rubber.

5. An apparatus as defined in claim 3 wherein said backing pad includes a thin layer of urethane.

6. A reusable orthopaedic brace or support comprising:

a gel pad assembly including a layer of gel;

said gel pad assembly having an impervious front plastic film for confining the gel in said gel pad assembly, for preventing contamination thereof and for preventing flow of said gel onto the user;

a backing layer extending across the rear of said gel, to confine said gel, and to prevent contamination thereof, said front plastic film being permanently bonded to said backing layer,

said plastic film defining the shape of the gel layer of said gel pad assembly and the thickness of the gel relative to said backing layer;

said gel pad assembly having a forwardly extending front surface which is formed of relatively flat gel material covered by said plastic film, and said assembly having other areas facing in the same direction as said front surface which are recessed back from said front surface;

said gel layer being formed into a plurality of zones by the engagement of said film with said backing layer; and

orthopaedic support means for holding said gel pad assembly against the back of a person'"'"'s neck to preclude excessive movement of the head.

7. A reusable orthopaedic brace or support including a gel pad assembly comprising:

a first continuous substantially flay backing foam sheet member;

a second substantially flat foam sheet member having an opening through it;

a layer of gel mounted in said opening and extending outwardly away from said two foam sheet members;

a thin impervious film of sheet material extending over the outwardly extending gel layer, and said film extending in through the opening around the periphery of the gel layer to confine it, while facilitating heat flow between the gel layer and the body of a user;

means for permanently securing said two foam layers together and to said thin film to form a resilient gel pad assembly with said gel layer covered by said impervious thin film protruding outwardly from the two foam layers and from said assembly; and

support means for holding said gel pad assembly against a portion of the body of the user and for limiting movement of the body of the user.

8. An orthopaedic brace for support as defined in claim 7 wherein the outer edges of said thin film are permanently secured in place between said two foam sheet members.

9. A reusable orthopaedic brace or support comprising:

a gel pad assembly including a layer of gel;

said gel pad assembly having an impervious thin front plastic film directly engaging and confining the gel in said gel pad assembly, for preventing contamination thereof and for preventing flow of said gel onto the user;

a backing layer extending across the rear of said gel, to confine said gel, and to prevent contamination thereof, said front plastic film being permanently bonded to said backing layer,

orthopaedic support means for holding said gel pad assembly against a portion of the anatomy of a user;

said plastic film defining the shape of the gel layer of said gel pad assembly and the thickness of the gel relative to said backing layer;

said gel pad assembly having a forwardly extending front surface which is formed of relatively flat gel material covered by said plastic film, and said assembly having other areas facing in the same direction as said front surface which are recessed back from said front surface;

said assembly permanently sealing the gel between the impervious front plastic film and the backing layer;

said gel pad assembly including two separate gel pads; and

means including two stiff plastic members for holding said gel pads against the inner and outer sides of a patient'"'"'s ankle.

10. A reusable orthopaedic brace or support comprising:

a gel pad assembly including a layer of gel;

said gel pad assembly having an impervious thin front plastic film for confining the gel in said gel pad assembly, for preventing contamination thereof and for preventing flow of said gel onto the user;

a backing layer extending across the rear of said gel, to confine said gel, and to prevent contamination thereof, said front plastic film being permanently bonded to said backing layer,

orthopaedic support means for holding said gel pad assembly against a portion of the anatomy of a user;

said plastic film defining the shape of the gel layer of said gel pad assembly and the thickness of the gel relative to said backing layer, and permanently confining said gel between said film and said backing layer; and

a peripheral enclosing aperture pad secured to said backing layer and extending around and enclosing the sides of the gel, while the gel and said plastic film extend forward from a plane defined by the front surface of said aperture pad.
