Abstract

The invention provides a self-adaptive control blood pump supply method. The self-adaptive control blood pump supply method comprises the following steps of collecting and processing a pulse signal; calculating a heart rate value according to the preprocessed pulse signal; and driving a servo motor to act according to the heart rate value so as to adjust the flow of an artificial blood pump. According to the method, heart blood pumping of a patient can be simulated, extracorporeal circulation blood perfusion generates pulse blood flow according with the patient, local brain oxygen saturation is improved, microcirculation of human tissue is improved, and blood pump parameters can be automatically adjusted according to different heart pulse frequencies of different patients, so that a blood transfusion process better conforms to the physiological characteristics of the patient. Correspondingly, the invention further provides a self-adaptive control blood pump supply system.

Description

technical field [0001] The present invention relates to the technical field of data processing, in particular to an adaptively controlled blood pump supply system and method. Background technique [0002] When rescuing a critically ill patient or performing an operation on a patient, it is often necessary to transfuse the patient with blood. As a medical device for clinical operations, the artificial blood pump plays an irreplaceable role in blood transfusion when assisting doctors in performing operations on patients. The pulsating artificial blood pump conforms to the physiological characteristics of the human body. By controlling the motor speed, the pulsating frequency of blood flow and the pumped blood volume of each pulsating cycle can be easily adjusted to generate pulsed blood flow and reduce the blood advective perfusion caused by extracorporeal circulation. damage to human organ tissues. [0003] However, the existing pulsating artificial blood pump cannot automa...
