Intelligent blood supply control system and method of two-channel blood pump

Abstract

The invention provides an intelligent blood supply control system of a two-channel blood pump. The intelligent blood supply control system comprises a pulse signal acquisition module, a pulse signal analysis module and a pulse signal control module. The pulse signal acquisition module is used for acquiring pulse signals and preprocessing the pulse signals, and the pulse signal analysis module is used for extracting dominant wave signals and dicrotic wave signals in the preprocessed pulse signals. The pulse signal control module is used for driving the first servo motor and the second servo motor to act according to the dominant wave signal and the dicrotic wave signal so as to adjust the flow of the first blood pump and the flow of the second blood pump. The device can simulate a human heart pumping mechanism to generate pulse type blood flow, so the blood conveying process for extracorporeal circulation of a human body better conforms to human physiological characteristics, the safety performance of an operation is reduced, the local brain oxygen saturation of the brain is improved, and the microcirculation of human tissues is improved. Correspondingly, the invention further provides an intelligent blood supply control method of the two-channel blood pump.

Description

Technical field[0001]The present invention relates to the field of data processing, and in particular, there is a smart bleeding control system and method for a dual-channel blood pump.Background technique[0002]With the improvement of living standards and the advancement of science and technology, people's requirements for intelligence and automation equipment are getting higher. The artificial blood pump is used as a clinical surgery, and the blood transfusion function has an irreplaceable effect when the auxiliary doctor is operative for patients. At present, most of the artificial blood pumps on the market are divided into three categories, respectively, the peristaltic blood transfusion pump, rolling blood pump and centrifugal blood pump. The blood perfusion state produced by these three types of artificial blood pumps is basically a constant speed state. Hematopcuff in vitro circulation in vitro to the human body will cause certain damage to the human organ tissue, reducing the...
