Abstract

Compression sleeve ( 1 ) for application circumferentially around a human limb ( 10 ) to exert therapeutic pressure on the limb. The compression sleeve has a fabric ( 80 ), which comprises viscoelastic strands ( 90 ) for providing the fabric with viscoelastic properties.

Claims (16)

1. Compression sleeve for application circumferentially around a human limb to exert therapeutic pressure on the limb, the compression sleeve comprising:

a compression section comprising a fabric;

wherein the fabric comprises viscoelastic strands for providing the fabric with viscoelastic properties and an elastic, non-viscoelastic strand with elastic properties to provide greater resistance against slow deformation; and

wherein a glass transition temperature of the viscoelastic strands is between 15° C. and 55° C., as determined by the position of a peak maximum of a graph of tan δ over temperature, where δ is a phase lag between elongation curve and force curve in a dynamic mechanical analysis run at an elongation frequency of 1 Hz, an amplitude of 75 μm and at a heat rate of 3° C./minute;

wherein two viscoelastic strands and one elastic non-viscoelastic strand are arranged parallel to each other, and such that the one elastic, non-viscoelastic strand is arranged between the two viscoelastic strands and adjacent to each of the two viscoelastic strands.

2. Compression sleeve according to claim 1 , wherein the viscoelastic strands are arranged such as to provide the fabric with viscoelastic properties in a circumferential direction when the sleeve is in use.

3. Compression sleeve according to claim 1 , wherein the fabric is a knitted or a woven or a non-woven fabric.

4. Compression sleeve according to claim 1 , wherein the compression section is arranged such as to exert therapeutic compression on the human limb, when the compression sleeve is in use.

5. Compression sleeve according to claim 1 , further comprising a zipper for facilitating removal of the compression sleeve from the limb.

6. Compression sleeve according to claim 5 , wherein the zipper is attached by sewing or welding or by an adhesive.

7. Compression sleeve according to claim 1 , wherein the viscoelastic strands comprise polyurethane, polyurea, polyether, polyester, poly(meth)acrylate, polyolefin, or polyvinyl chloride.

8. Compression sleeve according to claim 1 , wherein the viscoelastic strands are adapted for providing the fabric with viscoelastic properties at temperatures of between 15° C. and 55° C.

9. Compression sleeve according to claim 1 , further comprising a heating thread, arranged and adapted to heat one or more of the viscoelastic strands.

10. Compression sleeve according to claim 1 , wherein a density of the viscoelastic strands is between 1.5 and 40.0 strands per cm.

11. Compression sleeve according to claim 1 , wherein a linear mass density of the viscoelastic strands is 600 mg/m or less.

12. Compression sleeve according to claim 1 , comprising a calf section and a foot section, wherein the compression section comprises at least a portion of the calf section, further comprising a zipper extending axially when the sleeve is in use, wherein the viscoelastic strands have a linear mass density of 600 mg/m or less.
