Abstract

A compression device for a limb has a sleeve adapted to surround the limb. The sleeve has an inelastic layer and a cell constructed from an inner part joined to an outer part by one or more side walls. This construction provides a cell with a box-like configuration so that the inner part conforms to the shape of the limb, providing an even pressure to the limb, when the cell is inflated.

Claims (11)

1. A compression device for a limb comprising:

a sleeve adapted to surround the limb, the sleeve comprising an inelastic layer; and

at least two adjacent cells constructed from an inner part comprising a continuous surface joined to an outer part by one or more side walls so that at least one of the cells has a configuration which allows the inner part of the at least two adjacent cells to present a continuous surface of contact to the limb when the cell is inflated to provide an even pressure to the limb, and further wherein each of the at least two adjacent cells forms a portion of an external edge along a perimeter of the at least two adjacent cells and forms at least one internal edge between two adjacent cells, wherein the inner part and the outer part of each of the at least two adjacent cells is elastic and able to adopt the profile of the limb on inflation, wherein the sleeve, the inner part of the cell, and the outer part are co-planar layers, and further wherein at least a portion of the external edge of the at least two adjacent cells is fixed to the sleeve and the perimeter of the at least two adjacent cells lacks side walls, and wherein the at least one internal edge is provided with a side wall of the one or more side walls joining the inner part and the outer part.

2. The compression device for a limb as claimed in claim 1 , wherein the sleeve is divided into two or more cuffs, each cuff comprising at least one cell.

3. The compression device for a limb as claimed in claim 2 , wherein each cuff comprises more than one cell and the side walls of adjacent cells abut on inflation of the device.

4. The compression device for a limb as claimed in claim 1 , wherein the device further comprises:

a conduit attached to the sleeve for delivering fluid to the sleeve; and

a controller attached to the conduit that generates and controls the flow of fluid in the device.

5. The compression device for a limb as claimed in claim 1 , wherein the inelastic sleeve does not deform in use.

6. The compression device for a limb as claimed in claim 1 , wherein the outer part of each of the at least two adjacent cells is fixed to the sleeve.

7. A method for the treatment or prevention of venous leg ulcers, wherein the method comprises applying the compression device of claim 1 to a limb.
