Portable device for the enhancement of circulation of blood and lymph flow in a limb
First Claim
1. A portable device for enhancing circulation in a limb comprising:
- at least one adjustable strap for encircling the limb;
a limb-carried actuator comprising a motor and a mechanism driven by said motor for intermittently actuating a first transition from a relaxed state of said at least one strap to a strained state of said at least one strap and a second transition from the strained state to the relaxed state, the mechanism includes at least one spring operatively disposed between the motor and the at least one strap, and at least one energy releasing mechanism coupling between said at least one spring and said at least one strap;
wherein said at least one energy releasing mechanism is configured to enable fast release of energy stored in said at least one spring and the use of the energy so released to effectuate at least one abrupt transition between said relaxed and strained states.

Abstract
The present invention provides a portable device for enhancing circulation in a limb comprising at least one strap for encircling the limb, a motor and a mechanism driven by said motor for intermittently actuating a first transition from a relaxed state to a strained state of the strap and a second transition from the strained state to the relaxed state. The mechanism includes at least one energy storing element operatively disposed between the motor and the strap and at least one energy releasing mechanism coupling between the energy storing element and the strap. The energy releasing mechanism enables fast release of energy stored in said storing element and the use of the energy so released to effectuate at least one abrupt transition between said relaxed and strained states.

34. A portable device for enhancing circulation in a limb, the device comprising:
-
at least one motor; at least two parallel rollers; at least one strap comprising two portions for encircling the limb, each portion is having one end secured to one of the said at least two rollers and a second free end connectable to the free end of the other portion; and a mechanism driven by the motor for intermittently rotating the rollers in opposite directions to wind and unwind the strap around the rollers; wherein the mechanism comprises; a mainspring having one end coupled to the motor via a planetary transmission by means of mainspring clutch and a second end secured to a mainspring gear, the mainspring is configured to be loaded by the motor; a transmission gear assembly for transferring rotational motion of the mainspring gear to the rollers, the transmission assembly is configured to rotate the rollers in opposite directions, the transmission gear assembly is provided with a strap contraction clutch mechanism configured to prevent rotational motion of the rollers when the clutch is locked; a strap returning spring driven by the transmission gear assembly configured to be loaded when the mainspring is unloaded; and a timing assembly configured to unlock the strap contraction clutch for effectuating an abrupt winding of the strap around the rollers at a first predetermined time and to unlock the mainspring clutch for effectuating an abrupt unwinding of the strap at a second predetermined time. - View Dependent Claims (35, 36, 37, 38, 39)
