Portable device for the enhancement of circulation and for the prevention of stasis related DVT
First Claim
1. A portable limb squeezing device for therapeutically modifying circulation in a limb comprising a non-inflatable strap adapted to form a hold around a limb and a limb-carried actuator connectable to said strap adapted to repeatedly pulling and releasing said strap, thereby applying repetitive intermittent squeezing forces on said limb, wherein said actuator comprises at least one spring for allowing storage of energy.

Abstract
The present invention provides a portable device and method for enhancing blood flow in a limb and for reducing the risk of Deep Vein Thrombosis (DVT) formation by applying periodic squeezing forces on a limb, in particular a lower limb. The device comprises a flask-like casing box and a strap connected to opposite sides of said casing such as to form a closed loop around the limb. Said box contains machinery for actuating periodical change in the circumference of said closed loop between a contracted and a relaxed positions.

A portable limb squeezing device for therapeutically modifying circulation in a limb comprising a non-inflatable strap adapted to form a hold around a limb and a limb-carried actuator connectable to said strap adapted to repeatedly pulling and releasing said strap, thereby applying repetitive intermittent squeezing forces on said limb, wherein said actuator comprises at least one spring adapted for facilitating a quick transition between compression and relaxation of the limb.
- 17. A portable limb squeezing device for therapeutically modifying circulation in a limb comprising a non-inflatable strap adapted to form a hold around a limb and a limb-carried actuator connectable to said strap adapted to repeatedly pulling and releasing said strap, thereby applying repetitive intermittent squeezing forces on said limb, wherein the actuator comprises a mechanism coupled to at least one laterally movable connector connectable to the strap and wherein the mechanism intermittently changes positions of said at least one movable connector between an extended and a retracted positions.
- 21. A portable limb squeezing device for therapeutically modifying circulation in a limb comprising a non-inflatable strap adapted to form a hold around a limb and a limb-carried actuator connectable to said strap adapted to repeatedly pulling and releasing said strap, thereby applying repetitive intermittent squeezing forces on said limb, and a regulator for regulating the frequency of said intermittent squeezing forces.
- 25. A portable limb squeezing device for therapeutically modifying circulation in a limb comprising a non-inflatable strap adapted to form a hold around a limb and a limb-carried actuator connectable to said strap adapted to repeatedly pulling and releasing said strap, thereby applying repetitive intermittent squeezing forces on said limb, wherein the actuator comprises an electrical motor provided with a spinning shaft.
