Abstract

The disclosed compression device comprises a sleeve with straps for applying compression to a limb. The sleeve is provided with a plurality of rings in series releasably or fixedly attached by a strap. At least a portion of said strap is expandable. When the expandable portion is in its non-expanded state there is exteriorly a loop of material rising outwardly and when, in use under the provision of tension in the transverse direction of the sleeve, the expandable portion expands in the transverse direction and the loop flattens. The device further comprises a plurality of strip-shaped mechanical fastening tabs, wherein a single tab is provided for each ring. The tabs and rings are configured and arranged such that, in use, the tabs are passed through the rings, turned back on themselves such that the first lateral side edge of the sleeve is drawn towards the rings and then fastened so that the sleeve is tightened and restrained about the limb of the user.
