Abstract

An ankle calf exerciser/phlebo pump adapted to reduce the development of deep vein thromboses (DVT), leg edema, muscular atrophy and ankle joint stiffness in postoperative orthopedic patients. An efficient and simple driving mechanism is provided from imparting an alternating and reciprocating movement of a pair of foot paddles. The foot paddles are coupled to the driving mechanism such that only the patient's ankles will be flexed while the knee and hip remains stationary. This device is ideally suited for patients with hip fractures, and hip replacement with prosthesis. The speed of paddle reciprocation can be selected, as can the arcuate path of travel of the foot paddles by adjusting the length of a driving rod.
