PNEUMATIC CIRCULATORY ENHANCER FOR DIABETIC LEG THERAPY

摘要

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.

1. A pneumatic circulatory enhancer to enhance a blood flow of a leg of a patient, the pneumatic circulatory enhancer comprising:
a chamber that surrounds the leg and is filled with gas having a negative pressure, a zero-point pressure, or a positive pressure; a pneumatic gas pump having a cylinder and a piston that is connected to the chamber via a tube, the piston moving in the cylinder by an electrical motor; a plurality of ECG electrodes that are connected to body parts of the patient and detect ECG signals, which are indicators of heartbeats of the patient, from 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/pump-out the gas to/from the chamber by moving the piston inside the chamber, wherein the zero-point pressure is an atmospheric pressure that the pneumatic circulatory enhancer is operated, the negative pressure is any pressure smaller than the zero-point pressure, and the positive pressure is any pressure greater than the zero-point pressure.
