Abstract

A hand support including a base component arranged for securing to at least a portion of a hand, an anchor element adjustably connected to the base component and arranged for grasping a thumb, and a counterforce device connecting to the base component and the anchor element. The counterforce device arranged to generate a counterforce in combination with or against the base component and anchor element. The hand support may be arranged to provide traction for an extended period to remedy complications of the hand and associated joints.

First claim

The invention claimed is:

1. A hand support, comprising:
a base component arranged for securing to at least a portion of a hand, and forming a base opening adapted for insertion of a thumb, the base component having a dorsal portion and a palmar portion;
a strap extending from the palmar portion and adapted to wrap the hand or a wrist and secure to the dorsal portion;
a joint stabilizer secured to the base component and extending proximate to the base opening, the joint stabilizer having greater rigidity than the base component and extending from the dorsal portion to the palmar portion of the base component;
wherein the joint stabilizer is constructed from a malleable material;
an anchor element adjustably connected to the base component and arranged for grasping the thumb;
wherein a second end of the counterforce device holds the anchor element and is distally located relative to the base component;
wherein the counterforce device is arranged to generate a counterforce in combination with or against the base component and the anchor element, the counterforce device defining a helical spring spanning a distance between the base component and the anchor element, and arranged for encircling the thumb, the anchor element being biased by and rotatable relative to the counterforce device, the counterforce device being compressible in height relative to and from the base component.

2. The hand support of claim 1 , further comprising:
a counterforce device having a first end connecting to the base component and surrounding the base opening and extending distally therefrom.

3. The hand support of claim 2 , wherein the counterforce device is defined by a helical spring.

4. The hand support of claim 1 , wherein the anchor element includes at least one wedge portion located about and extending into a ring opening defined by the anchor element, the at least one wedge portion arranged to suspend the anchor element on the thumb and counteract forces exerted by the counterforce device.

5. The hand support of claim 4 , wherein the at least one wedge portion includes first and second wedges protruding from an inner surface of the anchor element and into the ring opening.

6. The hand support of claim 1 , wherein the joint stabilizer generally defines a J-shape, with a first end having a taper for mounting about a dorsal aspect of the hand, and a second end adapted for wrapping about at least part of a palmar aspect of the hand, the first and second ends extending from a base portion extending about a base of the thumb between dorsal and palmar aspects of the hand.

7. The hand support of claim 1 , wherein the joint stabilizer has first and second ends and a base portion located therebetween, the joint stabilizer having a greater thickness at the base portion than the first and second ends.

8. The hand support of claim 1 , wherein the dorsal portion extends oppositely from the palmar portion on opposite sides of the base opening.

9. The hand support of claim 1 , wherein a first end of the strap is arranged for pulling away from a buckle on one of the dorsal portion or palmar portion, and selectively and lockingly placed over a portion of the strap, and a second end of the strap is secured to another one of the dorsal portion or palmar portion.

10. The hand support of claim 1 , wherein the joint stabilizer is formed from thermoformed foam or reinforced polymeric material.

11. The hand support of claim 1 , wherein the anchor element is annular in shape and defines a ring opening, the anchor element is rotatably secured to the second end of the counterforce device.

12. The hand support of claim 1 , wherein the dorsal portion and palmar portion are arranged to extend and connect about a base of the thumb, both at or near a CMC joint and a thumb web.

13. The hand support of claim 1 , wherein the base component is formed from a material resilient to retain shape during use and arranged to be adjustable in shape according to articulation of the joint stabilizer.

14. The hand support of claim 1 , wherein the base component is thinner a distance from an opening of each of the dorsal portion and the palmar portion.

15. The hand support of claim 1 , further comprising at least one spacer arranged to connect to the base component about the base opening and protrude therefrom.

16. A hand support, comprising:
a base component arranged for securing to at least a portion of a hand, and forming a base opening adapted for insertion of a thumb, the base component having a dorsal portion and a palmar portion;
a strap extending from the palmar portion and adapted to wrap the hand or a wrist and secure to the dorsal portion;
a counterforce device having a first end connecting to the base component and surrounding the base opening and extending distally therefrom;
an anchor element adjustably connected to the base component and arranged for grasping the thumb, the anchor element being annular in shape and defining a ring opening, the anchor element is rotatably secured to a second end of the counterforce device;
wherein the second end of the counterforce device holds the anchor element and is distally located relative to the base component.

17. The hand support of claim 16 , wherein the counterforce device is arranged to generate a counterforce in combination with or against the base component and the anchor element, the counterforce device defining a helical spring spanning a distance between the base component and the anchor element, and arranged for encircling the thumb, the anchor element being biased by and rotatable relative to the counterforce device, the counterforce device being compressible in height relative to and from the base component.

18. A hand support, comprising:
a base component arranged for securing to at least a portion of a hand, and forming a base opening adapted for insertion of a thumb, the base component having a dorsal portion and a palmar portion;
a strap extending from the palmar portion and adapted to wrap the hand or a wrist and to secure to the dorsal portion;
a joint stabilizer secured to the base component and extending proximate to the base opening, the joint stabilizer having a greater rigidity than the base component and extending from the dorsal portion to the palmar portion of the base component;
a counterforce device having a first end connecting to the base component and surrounding the base opening and extending distally therefrom, the counterforce device having a first end connected to the base component proximate to the joint stabilizer;
an anchor element adjustably connected to the base component and arranged for grasping the thumb, the anchor element being annular in shape and defining a ring opening, the anchor element is rotatably secured to a second end of the counterforce device;
wherein the second end of the counterforce device holds the anchor element and is distally located relative to the base component;
wherein the counterforce device is arranged to generate a counterforce in combination with or against the base component and the anchor element, the counterforce device defining a helical spring spanning a distance between the base component and the anchor element, and arranged for encircling the thumb, the anchor element being biased by and rotatable relative to the counterforce device, the counterforce device being compressible in height relative to and from the base component.
