Abstract

A medical device for applying a cyclic therapeutic action to a subject'"'"'s foot, the device including a platform with at least three independently actuable inflatable bladders staggered therealong to solely underlie the subject'"'"'s heel, his plantar arch and his foot'"'"'s front portion including its metatarsals and its toes, respectively, whereby a travelling compressive wave can be cyclically applied to his foot'"'"'s underside only.

Claims

1. A medical device for applying a cyclic therapeutic action to a subject'"'"'s foot, the device comprising:

a boot having at least three independently actuable inflatable bladders arranged along the sole to underlie the subject'"'"'s heel, plantar arch and frontal foot portion including the metatarsals and toes;

a pressure source coupled to the bladders by a selfaligning, quick release connector; and

a controller coupled to the pressure source to regulate sequential application of pressure from the pressure source to the bladders to cyclically apply a traveling compressive wave to an underside of the subject'"'"'s foot only.

2. The device according to claim 1 wherein the at least three inflatable bladders are substantially co-extensive with sole of the boot.

3. The device according to claim 1 wherein the sole is provided with four inflatable bladders arranged to underlie the subject'"'"'s heel, plantar arch, metatarsals, and toes.

4. The device according to claim 1 wherein each inflatable bladder converges towards a laterally extending neck portion with an aperture that couples to the connector.

5. The device according to claim 4 wherein each neck portion is directed toward the medina side of the medical device.

6. The device according to claim 4 wherein the connector comprises first member and second magnetically coupled members, wherein the first member is permanently and attached to an exterior surface of the boot and the second member is coupled to the pressure source.

7. The device according to claim 6 wherein the connecter is disposed toward the heel of the boot.

8. The device according to claim 6 wherein the bladders are interdisposed between upper and lower sole members.

9. The device according to claim 8 wherein the upper sole member is peripherally attached to the first and second vamp halves.

10. The device according to claim 1, further comprising an arched plantar arch support for permanently supporting the subject'"'"'s plantar arch.

11. The device according to claim 10 wherein the plantar arch support has a maximum height above the sole of between 0.7 cm and 1.2 cm.

12. The device according to claim 1, further comprising an arched toe support for permanently supporting the subject'"'"'s toes.

13. The device according to claim 12 wherein the toe support has a maximum height above the sole of between 0.3 cm and 0.5 cm.

14. A medical device for applying a cyclic therapeutic action to a subject'"'"'s foot, the device comprising:

a sole having at least three inflatable bladders mounted thereon for selectively applying pressure to an underside of the subject'"'"'s foot;

a plurality of tubes extending from the at least three bladders and terminating in a connector adapted to be detachably coupled to a pressure source; and

a boot affixed to the sole, the boot comprising first and second vamp halves and a flap affixed to the first vamp half, the flap selectively fastenable to the second vamp half to fasten the boot to the subject'"'"'s foot, the connector affixed to the first vamp half adjacent to the flap so that the plurality of tubes are completely enclosed between the first vamp half and the flap.

15. The device according to claim 14 wherein each inflatable bladder converges towards a laterally extending neck portion with an aperture raised with respect to the sole.

16. The device according to claim 15 wherein each neck portion is directed toward the median side of boot.

17. The device according to claim 14 wherein said connector is disposed toward a heel of the boot.

18. The device according to claim 14 wherein the boot includes an inner sole construction including said sole interdisposed between upper and lower sole members.

19. The device according to claim 18 wherein the upper sole member is peripherally attached to the first and second vamp halves.

20. The device according to claim 14 wherein the at least three inflatable bladders are arranged to solely underlie the subject'"'"'s heel, plantar arch and a front portion of the subject'"'"'s foot including the subject'"'"'s metatarsals and toes.

21. The device according to claim 20 wherein the at least three inflatable bladders are substantially coextensive with the sole of the boot.

22. The device according to claim 14 wherein the sole is provided with four inflatable bladders disposed there along to underlie the subject'"'"'s heel, plantar arch, metatarsals and toes.

23. The device according to claim 14, further comprising an arched plantar arch support for permanently supporting a subject'"'"'s plantar arch.

24. The device according to claim 23 wherein said plantar arch support has a maximum height above the sole of between 0.7 cm and 1.2 cm.

25. The device according to claim 14, further comprising an arched toe support for permanently supporting a base portion of a subject'"'"'s toes.

26. The device according to claim 25 wherein the toe support has a maximum height above the sole of between 0.3 cm and 0.5 cm.
