Patent ID: 7618384

Claim:
A compression device for cyclically compressing the limb of a patient to improve blood flow in the limb, the compression device comprising: a compressive section sized and shaped for extending generally circumferentially around a portion of the limb for applying compressive circumferential pressure to the limb portion; a housing operatively connected to the compressive section, said housing including first and second rigid housing members combining to define an interior housing space, said first and second rigid housing members being movable relative to each other between a contracted position in which the housing has a first dimension for relaxing said circumferential pressure on said limb portion, and an expanded position in which the housing has a second dimension greater than said first dimension for compressing the limb portion circumferentially of the limb portion; and a non-pneumatic mechanical actuator comprising an electric motor in said interior housing space for cyclically moving the first and second housing members from said contracted position to said expanded position.
