Abstract

A dynamic hand splint including a hand support section, a sleeve configured to receive a digit therein, and a first tensioner having an elastic body and forming a loop, wherein the first tensioner is attached to the hand support section, as well as a first location of the sleeve, such that the first tensioner extends from the hand support section to the first location and a first joint of the digit. The elastic body of the first tensioner has sufficient flexural strength to resist, but not prevent, bending of the digit received within the sleeve such that, when the digit is flexed from an extended position toward a flexed position, the elastic body of the tensioner is elongated with the digit and the digit is urged by the tensioner toward the extended position.

Claims

1. A dynamic hand splint, comprising:

(a) a hand support section;

(b) a sleeve configured to receive a digit therein;

(c) a first tensioner having an elastic body forming a loop, wherein

(i) the first tensioner is attached to the hand support section, and

(ii) the first tensioner is attached to the sleeve at a first location of the sleeve, such that the first tensioner extends from the hand support section to the first location and is adapted to span a first joint of the digit; and

(d) a second tensioner having an elastic body forming a loop, wherein

(i) the second tensioner is attached to the sleeve at the first location and at a second location, such that

(ii) the second tensioner extends from the first location to the second location and is adapted to span a second joint of the digit;

(e) wherein the elastic body of the first tensioner has sufficient flexural strength to resist, but not prevent, bending of the digit received within the sleeve such that, when the digit is flexed from an extended position toward a flexed position, the elastic body of the first tensioner is elongated with the digit and the digit is urged by the first tensioner toward the extended position.

2. The dynamic hand splint of claim 1, further comprising a forearm support section configured to be releasably attached to a forearm, wherein the hand support section is connected to the forearm support section.

3. The dynamic hand splint of claim 2, wherein the forearm support section comprises a malleable material and includes a bend therein, whereby the forearm support section is configured to determine an angle at which a wrist will be disposed relative to the forearm when the forearm support section is donned.

4. The dynamic hand splint of claim 2, wherein the forearm support section and the hand support section are unitarily formed of a semi-rigid plastic material.

5. The dynamic hand splint of claim 1, wherein the sleeve further comprises a first mount that is attached to the sleeve at the first location and a second mount that is attached to the sleeve at the second location.

6. The dynamic hand splint of claim 5, wherein each of the first and second mounts defines a pair of hooks for attaching the corresponding tensioners to the first and second mounts.

7. The dynamic hand splint of claim 5, wherein the first mount and the second mount are adjacent the second joint of the digit.

8. The dynamic hand splint of claim 1, wherein the digit is a finger.

9. The dynamic hand splint of claim 1, wherein the digit is a thumb.

10. The dynamic hand splint of claim 1, wherein the first tensioner further comprises a resistive band.

11. The dynamic hand splint of claim 1, further comprising a plurality of posts depending outwardly from the hand support section so that the first tensioner may be attached to the hand support section at a plurality of locations.

12. A dynamic hand splint, comprising:

(a) a hand support section;

(b) a sleeve configured to receive a digit therein;

(c) a first tensioner having an elastic body forming a loop, wherein

(i) the elastic body of the first tensioner is attached to the sleeve at a first location, and

(ii) the elastic body of the first tensioner is attached to the sleeve at a second location of the sleeve, such that the elastic body extends from the first location to the second location and is adapted to span a first joint of the digit;

(d) a second tensioner having an elastic body forming a loop, wherein the second tensioner is attached to the hand support section, and is attached to the sleeve at the first location such that the elastic body of the second tensioner extends from the hand support section to the first location and is adapted to span a second joint of the digit; and

(e) wherein the elastic body of the first tensioner has sufficient flexural strength to resist, but not prevent, bending of the digit received within the sleeve such that, when the digit is flexed from an extended position toward a flexed position, the elastic body of the first tensioner is elongated with the digit and the digit is urged by the first tensioner toward the extended position.

13. The dynamic hand splint of claim 12, further comprising a forearm support section configured to be releasably attached to a forearm, wherein the hand support section is connected to the forearm support section.

14. The dynamic hand splint of claim 13, wherein the forearm support section comprises a malleable material and includes a bend therein, whereby the forearm support section is configured to determine an angle at which a wrist will be disposed relative to the forearm when the forearm support section is donned.

15. The dynamic hand splint of claim 13, wherein the forearm support section and the hand support section are unitarily formed of a semi-rigid plastic material.

16. The dynamic hand splint of claim 12, wherein the sleeve further comprises a first mount that is attached to the sleeve at the first location and a second mount that is attached to the sleeve at the second location.

17. The dynamic hand splint of claim 16, wherein each of the first and second mounts defines a pair of hooks for attaching the first tensioner to the first and second mounts.

18. The dynamic hand splint of claim 16, wherein the first mount and the second mount are adjacent the first joint of the digit.

19. The dynamic hand splint of claim 12, wherein the digit is a finger.

20. The dynamic hand splint of claim 12, wherein the digit is a thumb.

21. The dynamic hand splint of claim 12, wherein the first tensioner further comprises a resistive band.

22. The dynamic hand splint of claim 12, further comprising a plurality of posts depending outwardly from the hand support section so that the first tensioner may be attached to the hand support section at a plurality of locations.
