Abstract:
1. A device for enhancing circulation by intermittently tightening and relaxing a closure encircling a limb, the device comprising a motor, at least one rotating element and a mechanism driven by said motor for intermittently rotating said at least one rotating element in at least one of a first direction to tighten said closure and a second opposite direction to relax said closure, thereby applying a cyclic pressure on the limb; wherein a pressure cycle comprises a first period of relaxed state followed by a first transition to a compressed state and a second period of a compressed state followed by a second transition back to the relaxed state, and wherein the mechanism includes at least one spring coupled to said rotating element, said at least one spring is configured to be charged by said motor during at least the first period and to be discharged to effectuate at least one of said first and second transitions.
