Abstract

The pneumatic Achilles sleeve assembly comprises a sleeve and at least one strap for fastening the sleeve around the ankle. The sleeve assembly positions an arch cell which contains a dynamic volume of air within the sleeve under a human foot. The arch cell is fabricated from a flexible material and is in communication with a conduit member. Upon application of external pressure to the arch cell, air is expelled from said air cell through said conduit member. The sleeve assembly also positions a tendon cell which contains a dynamic volume of air within the sleeve against the Achilles tendon. The tendon cell is in communication with the arch cell via the conduit member. The tendon cell is also fabricated from a flexible material. Upon the expelling of air from said arch cell, the air enters through the conduit member into the tendon cell which exerts a greater pressure against the Achilles tendon.

Claims (64)

1. A pneumatic ankle support system, comprising

a sleeve having a foot cuff comprising a fabric wall having a permanent transverse seal that forms a permanently continuous tube surrounding the circumference of a user's foot in the region of the arch,

a first cell positioned along a bottom portion of the user's foot under the arch and having a volume that is adjustable by the user,

a second cell positioned along the user's Achilles tendon, and

an inelastic strap that extends behind the second cell to a front portion of the user's ankle to confine inflation of the second cell.

2. The system of claim 1 , comprising a conduit adapted to allow a fluid to flow between the first cell and the second cell.

3. The system of claim 2 , wherein the conduit is a tube in air communication with the first and second cells.

4. The system of claim 1 wherein the system is adapted to inflate the second cell when pressure is applied to the first cell.

5. The system of claim 1 , comprising a strap for positioning the second cell along the Achilles tendon.

6. The system of claim 5 , wherein the strap is adapted to releasably open and close around the user's ankle.

7. The system of claim 1 , wherein the system is adapted to press the second cell against the user's Achilles tendon when pressure is applied to the first cell.

8. The system of claim 1 , wherein the system is adapted to press the first cell against the bottom portion of the user's foot when pressure is applied to the first cell.

9. The system of claim 1 , wherein at least one of the first and second cells includes open cell foam.

10. The system of claim 1 , wherein at least one of the first and second cells is made of sealable material.

11. The system of claim 1 , wherein the first cell deflates when pressure is applied to the first cell.

12. The system of claim 1 , wherein the first cell inflates when pressure is relieved from the first cell.

13. The system of claim 1 , wherein the sleeve is stretchable.

14. The system of claim 1 , wherein the sleeve has a pocket disposed under the bottom of the user's foot, and the first cell is positioned within the pocket.

15. The system of claim 1 , wherein the sleeve is adapted to surround the user's foot in the region of the arch of the foot.

16. The system of claim 1 , wherein the foot cuff includes a substantially tubular proximal end adapted to slide onto the user's foot.

17. The system of claim 1 , wherein the first cell is adapted to be positioned under the arch of the user's foot.

18. The system of claim 1 , wherein the first cell is sealed within the permanently continuous tube.

19. The system of claim 1 , wherein the foot cuff has first and second flexible layer that extend under the user's arch.

20. The system of claim 19 , wherein the first cell has first and second sealed walls embedded between the first and second flexible layers.

21. The system of claim 19 , wherein the first flexible layer comprises a first material and the second layer comprises a second material, wherein the first material is thicker than the second material.

22. The system of claim 1 , wherein the sleeve includes first and second side flaps extending laterally around to envelop the user's leg.

23. The system of claim 22 , wherein the inelastic strap has a first end fixedly secured to the outer surface of the first side flap.

24. The system of claim 22 , wherein the first side flap has a slit disposed on the outer surface to allow the inelastic strap to pass therethrough.

25. The system of claim 1 , wherein the second cell includes a first wall and a second wall juxtaposed against the first wall.

26. The system of claim 25 , comprising a slit disposed in the second wall, the slit being adapted to accommodate the inelastic strap.

27. The system of claim 26 , wherein the inelastic strap passes through the slit.

28. The system of claim 22 , wherein the inelastic strap extends along an inner surface of the second side flap and is fixedly attached to an outer edge of the second side flap at an attachment site.

29. The system of claim 28 , wherein the inelastic strap extends along an inner surface of the second side flap and engages the first side flap.

30. The system of claim 25 , wherein the second wall has a strip material disposed on the outer surface, the material being adapted to engage with a strip of mating material disposed on an inner surface of the rear portion of the sleeve.

31. A pneumatic ankle support system, comprising

a sleeve having a foot cuff comprising a fabric wall having a permanent transverse seal that forms a permanently continuous tube surrounding the circumference of a user's foot in the region of the arch, the foot cuff having first and second flexible layers that extend under the user's arch,

a first cell having first and second sealed walls embedded between the first and second flexible layers under the user's arch,

a second cell adapted to be positioned along the user's Achilles tendon, an inelastic strap that extends behind the second cell to a front portion of the user's ankle to confine inflation of the second cell, and

a conduit adapted to allow a fluid to flow between the first cell and the second cell.

32. The system of claim 31 , wherein the fluid is air.

33. The system of claim 31 , wherein the second cell is positionable along the Achilles tendon by a strap.

34. The system of claim 31 , wherein at least one of the first and second cells is an air cell.

35. The system of claim 31 , wherein at least one of the first and second cells contains a foam pad.

36. The system of claim 31 , wherein the first cell is adapted to inflate the second cell when pressure is applied to the first cell.

37. The system of claim 31 , wherein the system is adapted to press the second cell against the user's Achilles tendon when pressure is applied to the first cell.

38. The system of claim 31 , wherein the system is adapted to press the first cell against the bottom portion of the user's foot when pressure is applied to the first cell.

39. The system of claim 31 , wherein at least one of the first and second cells includes flexible material.

40. The system of claim 31 , wherein the foot cuff includes a substantially tubular proximal end adapted to slide onto the user's foot.
