Abstract

A patient arm support comprises a first elongate resilient segment extending along an axis having a top and a bottom surface, the bottom surface being configured to rest upon a substantially planar surface and the top surface being configured to support an upper portion of the patient'"'"'s arm. A second elongate resilient segment extends along the axis and also has a top and a bottom surface, the bottom surface being configured to rest upon a substantially planar surface and the top surface being configured to support a lower portion of the patient'"'"'s arm. In one embodiment a void provides axial separation between the top surfaces of the first and second resilient segments. The void is configured to receive the ulnar nerve at the elbow of the patient without the ulnar nerve contacting a surrounding surface. In another embodiment the second elongate resilient segment is inclined upward as it extends away from the first elongate resilient segment. In another embodiment a lengthwise channel is provided in the top surface of the second elongate resilient segment to receive and secure a patient'"'"'s hand in a neutral position. Embodiments may include combinations of these features.

Claims

1. A patient arm support comprising:

a first elongate resilient segment extending along an axis having at top and a bottom surface, the bottom surface being configured to rest upon a substantially planar surface and the top surface being configured to support an upper portion of the patient'"'"'s arm;

a second elongate resilient segment extending along the axis having a top and a bottom surface, the bottom surface being configured to rest upon the substantially planar surface and the top surface being configured to support a lower portion of the patient'"'"'s arm; and

a void providing axial separation between the top surface of the first resilient segment and the top surface of the second resilient segment, the void being configured to receive the ulnar nerve at the elbow of the patient without contacting a surrounding surface.

2. The patient arm support of claim 1 further comprising the first resilient segment and the second resilient segment being integrally formed from a single resilient piece.

3. The patient arm support of claim 1 further comprising a third resilient segment underlying the void.

4. The patient arm support of claim 3 further comprising the first, second and third resilient segments each being integrally formed from a single resilient piece.

5. The patient arm support of claim 1 further comprising the top surface of the second elongate resilient segment being inclined upward as the top surface extends axially from the void.

6. The patient arm support of claim 1 further comprising the elongate resilient segments being made of resilient foam.

7. The patient arm support of claim 6 wherein the resilient foam is selected from the group consisting of open cell polyurethane, open cell ester, latex rubber, closed cell neoprene and closed cell polyethylene.

8. The patient arm support of claim 6 wherein the top surface of the resilient foam has an egg crate configuration.

9. The patient arm support of claim 1 further comprising at least one strap attached to one of the first and second elongate resilient segments, the strap being configured to attach the patient'"'"'s arm thereto.

10. The patient arm support of claim 1 further comprising a lengthwise channel formed in the upper surface of at least one of the first and second elongate resilient segments.

11. The patient arm support of claim 10 wherein the lengthwise channel comprises a cut in the top surface of the second elongate resilient segment.

12. The patient arm support of claim 5 further comprising a lengthwise channel in the top surface of the second elongate resilient segment.

13. The patient arm support of claim 12 further comprising a lengthwise channel formed in the top surface of the first elongate resilient segment.

14. The patient arm support of claim 1 further comprising a removable plug in the void configured to fill the void and transition between the top surfaces of the first and second elongate resilient segments.

15. The patient arm support of claim 6, further comprising the resilient foam being compressed in a compressed state to minimize its volume and contained with packaging configured to maintain the resilient foam in its compressed state.

16. The patient arm support of claim 15 wherein the packaging comprises a vacuum evacuated and heat-sealed sheets of plastic.

17. The patient arm support of claim 1 further comprising a fin extending from the top surface of the second elongate resilient segment near its distal end.

18. The patient arm support of claim 17 further comprising a lengthwise channel in a top surface of the fin configured to receive a portion of a patient'"'"'s hand.

19. The patient arm support of claim 1 further comprising the elongate resilient segments being made of a thin plastic inflatable material.

27. The patient arm support of claim 19 further comprising the elongate resilient segments being made of a thin plastic inflatable material.

20. A patient arm support comprising:

a first elongate resilient segment extending along an axis having at top and a bottom surface, the bottom surface being configured to rest upon a substantially planar surface and the top surface being configured to support an upper portion of the patient'"'"'s arm;

a second elongate resilient segment attached to the first elongate resilient segment extending along the axis having a top and a bottom surface, the bottom surface being configured to rest upon the substantially plainer surface and the top surface being configured to support a lower portion of the patient'"'"'s arm; and

a lengthwise channel in the top surface of the second elongate resilient segment, the lengthwise channel being configured to receive a portion of a patient'"'"'s hand to secure the portion of the patient'"'"'s hand against movement relative to the second elongate resilient segment.

21. The patient arm support of claim 20 wherein the lengthwise channel comprises a cut in the top surface of the second elongate resilient segment.

22. The patient arm support of claim 20 further comprising a void providing axial separation between the top surface of the first resilient segment and the top surface of the second resilient segment, the void being configured to receive the ulnar nerve at the elbow of the patient without contacting a surrounding surface.

23. The patient arm support of claim 20 further comprising the elongate resilient segments being made of resilient foam.

24. The patient arm support of claim 23 wherein the resilient foam is selected from the group consisting of open cell polyurethane, open cell ester, latex rubber, closed cell neoprene and closed cell polyethylene.

25. The patient arm support of claim 22 further comprising a removable plug in the void configured to fill the void and transition between the top surfaces of the first and second elongate resilient segments.

26. The patient arm support of claim 20 further comprising a lengthwise channel in the top surface of the first elongate resilient segment.

28. A patient arm support comprising:

a first elongate resilient segment extending along an axis having at top and a bottom surface, the bottom surface being configured to rest upon a substantially planar surface and the top surface being configured to support an upper portion of the patient'"'"'s arm; and

a second elongate resilient segment attached to the first elongate resilient segment extending along the axis having a top and a bottom surface, the bottom surface being configured to rest upon the substantially planar surface and the top surface being configured to support a lower portion of the patient'"'"'s arm, the top surface of the second elongate resilient segment being inclined upward as the top surface extends axially away from the first elongate resilient segment.

29. The patient arm support of claim 28 further comprising a lengthwise channel formed in the top surface of the second elongate resilient segment, the lengthwise channel being configured to receive a portion of a patient'"'"'s hand to secure the portion of the patient'"'"'s hand against movement relative to the second elongate resilient segment.

30. The patient arm support of claim 29 further comprising a lengthwise channel formed in the top surface of the first elongate resilient segment.
