ABSTRACT:
There is provided a non-invasive pulsation and counterpulsation medical treatment apparatus for treating reduced cardiac output in heart patients. A flexible cuff is passed over the patient's lower body and/or extremities, and is attached through a lever arm to an electromechanical actuator. Through a mechanical linkage, the actuator sequentially tensions and releases the cuff, thereby sequentially compressing and releasing pressure on the patient, and thereby augmenting the patient's blood pressure. The actuator includes an electric solenoid which axially extends and retracts a shaft. The shaft oscillates the lever arm. A curved plate on the apparatus supports the patient's body or extremity in a fixed position during the treatment. A pressure sensor in the cuff transmits pressure data to an operator or electronic processor. Based on physiological data continuously obtained from the patient, various treatment parameters may be changed during the patient's treatment by an attending clinician or by a computer processor controlling the treatment.
