## Abstract

A cylindrical bandage is held in place without using binding means such as strings tied to an upper limb. Additionally, the cylindrical bandage for a lower limb or upper limb fits the shapes and dimensions of a body part and stays on the body part and thus allows great increase in venous return. The cylindrical bandage includes a tubular knit being of a length corresponding to a length of an arm or a leg and a gutter-shaped knit extending from a lengthwise first end of the tubular knit. This gutter-shaped knit has smaller circumferential length than the first end of the tubular knit and has a cut-out section with a horseshoe or V shape.

## Claims

### Claim 1

A cylindrical bandage, comprising:
a tubular knit; and
a gutter-shaped knit extending from a lengthwise first end of the tubular knit, the gutter-shaped knit having a smaller length in a circumferential direction than the first end of the tubular knit, the gutter-shaped knit having a variation in a number of wales and a horseshoe-shaped cut-out section at a lateral side of the gutter-shaped knit, wherein the horseshoe-shaped cut-out section has a bottom edge being a lengthwise extension of the tubular knit, and
wherein a top end of the gutter-shaped knit is formed congruently with the bottom edge of the horseshoe-shaped cut-out section.

### Claim 2 (depends on 1)

The cylindrical bandage according to claim 1, wherein
the gutter-shaped knit has a thickness in a range of 2 to 15 mm and the tubular knit has a thickness in a range of 2 to 15 mm.

### Claim 3 (depends on 1)

The cylindrical bandage according to claim 1, wherein
the tubular knit has a second end placed on a foot part configured to correspond to metatarsal bones.

### Claim 4 (depends on 1)

The cylindrical bandage according to claim 1, wherein
the tubular knit has a second end placed on a hand part configured to correspond to metacarpal bones.

### Claim 5 (depends on 1)

The cylindrical bandage according to claim 1, wherein
the gutter-shaped knit is symmetrical about a center perpendicular line in an extended configuration of the gutter-shaped knit and the tubular knit.

### Claim 6 (depends on 1)

The cylindrical bandage according to claim 1, wherein the gutter-shaped knit and the tubular knit have a base structure formed of stitches of a base yarn; and
the base structure includes stitches of an elastic yarn.

### Claim 7

A cylindrical bandage, comprising:
a tubular knit; and
a gutter-shaped knit extending from a lengthwise first end of the tubular knit, the gutter-shaped knit having a smaller length in a circumferential direction than the first end of the tubular knit, the gutter-shaped knit having a gutter shape and a horseshoe-shaped cut-out section at a lateral side of the gutter-shaped knit, wherein the horseshoe-shaped cut-out section has a bottom edge being a lengthwise extension of the tubular knit, and
wherein a top end of the gutter-shaped knit is formed congruently with the bottom edge of the horseshoe-shaped cut-out section,
wherein the tubular knit and the gutter shaped knit have inner protuberances and outer protuberances extending along a longitudinal direction of the bandage; and
the inner protuberances and outer protuberances have one end on a symmetrical line of the bandage.

### Claim 8

A cylindrical bandage, comprising:
a tubular knit configured to correspond to a humerus bone, an elbow, a radius and an ulna; and
a gutter-shaped knit extending from a lengthwise first end of the tubular knit, the gutter-shaped knit having a smaller length in a circumferential direction than the first end of the tubular knit, the gutter-shaped knit having a variation in a number of wales and a horseshoe-shaped cut-out section at a lateral side of the gutter-shaped knit, wherein the horseshoe-shaped cut-out section has a bottom edge being a lengthwise extension of the tubular knit, and
wherein a top end of the gutter-shaped knit is formed congruently with the bottom edge of the horseshoe-shaped cut-out section,
wherein the tubular knit and the gutter-shaped knits are comprised of inner protuberances, outer protuberances, and a base yarn.

### Claim 9

A cylindrical bandage, comprising:
a tubular knit configured to correspond to a femur, tibia, a fibula bones, a heel and a foot; and
a gutter-shaped knit extending from a lengthwise first end of the tubular knit, the gutter-shaped knit having a smaller length in a circumferential direction than the first end of the tubular knit, the gutter-shaped knit having a variation in a number of wales and a horseshoe-shaped cut-out section at a lateral side of the gutter-shaped knit, wherein the horseshoe-shaped cut-out section has a bottom edge being a lengthwise extension of the tubular knit, and
wherein a top end of the gutter-shaped knit is formed congruently with the bottom edge of the horseshoe-shaped cut-out section.
