Patent ID: 8764689

Claim:
A device for compressive treatment of a body part of a user, the device comprising: a compression member predeterminedly dimensioned to at least partly encircle the body part; and an actuation unit cooperating with the compression member to tighten the compression member and provide a compressive force to the body part, wherein the actuation unit is arranged to stepwise tighten the compression member, wherein the compressive force to the body part is provided by a compression stroke resulting from operation of the actuation unit, wherein the actuation unit comprises: an active material actuator, a gripping member connected to the actuator to perform a cyclic motion over a plurality of cycles, wherein at least hundreds of cycles are used to provide the compression stroke, and a movable member engaged by the gripping member and connected to the compression member, wherein the movable member during a first part of the cyclic motion is movable with the gripping member and during a second part of the cyclic motion is movable relative to the gripping member.
