Abstract
The present invention provides a device for enhancing circulation by intermittently tightening and relaxing a closure encircling a limb. The device comprises a continuously operating motor, at least one rotating element and a mechanism driven by the motor for intermittently rotating the rotating element in a first direction to tighten the closure and in a second opposite direction to relax the closure, thereby applying a cyclic pressure on the limb.
Claims51
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.
A portable device for enhancing circulation by intermittently tightening and relaxing a closure encircling a limb, the device comprising:
- a continuously operating motor;
- at least one rotating element and a first clutch for locking/unlocking said at least one rotating element for preventing/allowing rotation of the element;
- a mainspring having a first end coupled to said at least one rotating element and a second end coupled/decoupled to said motor by means of a second clutch;
- and
- a first and a second disengaging elements configured to intermittently unlock said first clutch and said second clutch, respectively.
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:
- a mechanism driven by said motor for intermittently rotating said at least one rotating element at least one of a first direction to tighten said closure and a second opposite direction to relax said closure:
- and
- a sensor for monitoring the device activity;
- wherein said sensor is located opposite a rotating component that is coupled to the at least one rotating element, the rotating component reflects the rotational movement of said at least one rotating element, and wherein the rotating component is provided with at least one marker configured to be detected by the sensor.
