Abstract
A pneumatic circulatory enhancer to enhance a blood flow of a leg of a patient that includes a chamber that surrounds the leg and is filled with gas having a negative, a zero-point, or a pressure, a pneumatic gas pump having a cylinder and a piston, the piston moving in the cylinder by an electrical motor, a plurality of ECG electrodes that are connected to body parts of the patient, a pressure sensor that is connected to the chamber and measures a pressure of the gas inside the chamber, a controller that receives the ECG signals from the plurality of ECG electrodes and controls the electrical motor based on the received ECG signals to pump-in or pump-out the gas from the chamber by moving the piston inside the chamber such that the zero-point pressure is an atmospheric pressure of a location that the pneumatic circulatory enhancer is operated.
