Abstract
A compression therapy device for vascular diseases and other therapies comprising a bladder a lever arm acting on the outer surface of the bladder such that cyclical operation of an actuator on the lever arm creates cyclical changes in pneumatic pressure in the therapeutic portion of the bladder.
Claims20
A compression therapy device comprising:
- a bladder adapted to be applied against at least a portion of a patient's body part, said bladder being pre-filled with at least one of a gas, a liquid and non-Newtonian liquid at a pre-set fill pressure;
- a lever arm shaped and oriented to compress against said bladder in a first position and at least partially release compression against said bladder in a second position;
- an actuator coupled to said lever arm such that actuation of said actuator causes said lever arm to pivot to said first position;
- and
- a control operatively coupled to said actuator and configured to actuate said actuator in a cyclic manner according to at least one of a therapeutic timing cycle.

A compression therapy device comprising:
- a bladder adapted to be applied against at least a portion of a patient's body part, said bladder being pre-filled with at least one of a gas, a liquid and non-Newtonian liquid at a pre-set fill pressure;
- and
- a means for cyclically compressing against an outer surface of said bladder according to a therapeutic timing cycle.
A method of compression therapy comprising the steps of:
- selecting a compression therapy device having a housing containing a bladder adapted to be applied against at least a portion of a patient's body part, a pressure source for providing at least one of pneumatic and hydraulic pressure within said bladder, a lever arm shaped and oriented to compress against an outer surface of said bladder when pivoted to a first position and to at least partially release compression against said outer surface of said bladder when pivoted to a second position, and an actuator attached to said lever arm such that actuation of said actuator pivots said lever arm to said first position, thereby creating an increased pneumatic or hydraulic pressure within said bladder;
- actuating said actuator to pivot said lever to said first position;
- inserting a patient's body part into said housing and against said bladder;
- inflating said bladder by said pressure source to a maximum desired therapeutic pressure;
- cyclically operating said actuator to pivot said lever arm at least between said first and second positions according to a therapeutic timing cycle.
