Pulsatile flow blood pump
First Claim
1. A blood pump for providing pulsatile blood flow with cardiopulmonary by-pass devices and the supportive devices of circulation system, wherein the blood pump enables pulsatile blood flow by running systolic and diastolic intermittently like a healthy human heart, and comprisesa pulsatile blood pump,wherein the pulsatile blood pump includesa rotor, wherein the rotor is a hollow cylinder without a shaft, the rotor having helical wings disposed inside the rotor,a stator that rotates the rotor,a magnetic bearing inside the stator, wherein the rotor rotates frictionlessly in the magnetic bearing;
- anda control unit;
wherein the control unit comprisesan ECG connection configured to provide an ECG data of a patient to the control unit,a pressure sensor configured to measure a blood pressure data,a blood flow sensor configured to measure a blood flow data,an oxygen saturation sensor configured to measure an oxygen level in the blood,an air cavitation sensor configured to detect presence of an air bubble in the blood,a microprocessor configured to receive and process the ECG data, the blood pressure data, the blood flow data and the oxygen level in the blood, and control functioning of the pulsatile blood pump accordingly.

Abstract
The invention is about a next-generation blood pump that provides pulsatile blood flow, and has been developed for cardiopulmonary by-pass devices used for maintaining extracorporeal blood circulation during heart surgeries and the supportive devices of circulation system. This device is technically a sort of synchronous power-assisted motor employing direct driver technology. The mentioned blood pump contains a rotor rotating on a magnetic bearing without a shaft and through the helical wings placed into the rotor it provides pulsatile blood supply adequate for the body requirement synchronous with the ECG signals received from the patients. It provides a patient safer and controlled pulsatile blood flow while running at high efficiency.
