Abstract

A compression stocking for compressing a limb is disclosed. The stocking may include a proximal tube, a distal tube, and an transition line or zone. The proximal tube may have a distal end and a proximal end and be configured to compress a proximal portion of a limb. The distal tube may have a distal end and a proximal end and be configured to compress a distal portion of the limb. The transition line or zone may provide a location where the distal end of the proximal tube connects to the proximal end of the distal tube. The transition line or zone may correspond to an abrupt change in magnitude between compression provided by the proximal tube and compression provided by the distal tube.

Claims (50)

1. A compression stocking for compressing a limb, the stocking comprising:

a first portion configured to apply to a proximate portion of the limb compression of about 10 mmHg or less;

a second portion configured to apply to a distal portion of the limb compression within the range of about 20 mmHg to about 50 mmHg;

the first and second portions each comprising a distal end and a proximal end and forming a tube extending from the distal end to the proximal end; and

a transition zone wherein the distal end of the first portion connects to the proximal end of the second portion.

2. The stocking of claim 1 , further comprising at least one compression band configured to encircle the first portion and apply compression to the proximate portion of the limb.

3. The stocking of claim 2 , wherein the at least one band comprises material selected from the group consisting of non-elastic material, short-stretch material, and elastic material.

4. The stocking of claim 1 , wherein:

the first portion forms a tube that is seamless;

the proximal end of the first portion is open to receive the limb therewithin; and

the distal end of the second portion is closed.

5. The stocking of claim 4 , wherein the second portion is formed of knitted material.

6. The stocking of claim 1 , wherein the first portion is configured to apply to the proximal portion of the limb compression of about 5 mmHg or less.

7. The stocking of claim 6 , wherein the second portion is configured to apply to the distal portion of the limb compression of 30 mmHg or greater.

8. The stocking of claim 7 , wherein the first portion is configured to apply to the proximal portion of the limb compression of about 2 mmHg.

9. The stocking of claim 1 , wherein:

the first portion functions substantially exclusively as a liner; and

the second portion functions as a therapeutic compression device.

10. A compression stocking comprising:

a proximal tube having a distal end and a proximal end and being configured to compress a proximal portion of a leg;

a distal tube having a distal end and a proximal end and being configured to compress a distal portion of the leg;

a transition zone wherein the distal end of the proximal tube connects to the proximal end of the distal tube; and

the transition zone corresponding to an abrupt change in magnitude between a lower compression provided by the proximal tube and a higher compression provided by the distal tube, the transition zone configured to be positioned proximate an ankle of the leg.

11. A method comprising:

identifying a human leg in need of therapeutic compression;

obtaining a hybrid compression stocking for the human leg, the hybrid compression stocking comprising

a proximal tube having a distal end and a proximal end,

a distal tube having a distal end and a proximal end, and

a transition zone connecting the distal end of the proximal tube to the proximal end of the distal tube;

inserting a foot of the human leg through the proximal tube and into the distal tube;

positioning, via the inserting, the compression stocking on the human leg with the transition zone proximate an ankle of the human leg;

providing, by the proximal tube, non-therapeutic compression to a proximal portion of the leg; and

providing, by the distal tube, therapeutic compression to a distal portion of the leg.

12. The method of claim 11 , further comprising providing, by the compression stocking within the transition zone, an abrupt change in magnitude between compression provided by the proximal tube and compression provided by the distal tube.

13. The method of claim 12 , wherein:

the hybrid compression stocking further comprises

a joint tube having a distal end and a proximal end, and

a second transition zone connecting the distal end of the joint tube to the proximal end of the proximal tube;

the inserting further comprises inserting the foot through the joint tube and second transition zone;

positioning further comprises positioning the joint tube over a knee of the leg; and

the method further comprises providing, by the joint tube, therapeutic compression to the knee of the leg.

14. The method of claim 11 , wherein:

the proximal end of the proximal tube is open to receive the human leg therewithin; and

the distal end of the distal tube is closed.

15. The method of claim 11 , wherein the distal tube is formed of knitted material.

16. The method of claim 11 , further comprising providing, by the proximal tube to the proximal portion of the human leg, compression of about 10 mmHg or less.

17. The method of claim 16 , further comprising providing, by the distal portion to the distal portion of the human leg, compression within the range of about 20 mmHg to about 50 mmHg.

18. The method of claim 11 , wherein the positioning comprises positioning, via the inserting, the compression stocking on the human leg such that the transition zone is positioned adjacent the ankle on a proximal side thereof.

19. The method of claim 11 , further comprising securing at least one band over the proximal portion of the compression stocking and around the human leg to augment venous calf muscle return thereof.

20. The method of claim 19 , wherein the at least one band comprises short-stretch material with a maximum elastic range of 15% up to 100% of an unstretched condition.
