The Design Of Cardiac Assist Monitoring System Based On LabVIEW

In modern society, as the increase in the number of patients with heart failure, heart disease has threat the safety of human life, to serious heart failure patients, the traditional treatment effect is poorer, mortality is higher, and effective donor heart transplant due to the scarcity, so many heart failure patients died while waiting the source of the process, and end-stage heart failure patients in the treatment and care they consume a lot of resources. Cardiac circulatory support device as a senior clinical medical equipment, portability and security of the device is its main indicators, namely the development of effective heart assist device monitoring system.Based on the analysis of the basis of modern circulation ventricular assist device monitoring system development based on the design of the lower computer hardware circuitry auxiliary devices real-time monitoring, and virtual instrument host computer and interactive platform cardiac assist device monitoring system. First, based on ventricular assist circulation means for monitoring system designed hardware circuitry next crew; secondly, the PC interactive platform Lab VIEW software development platform for real-time monitoring of heart assist device designed user login system, and the blood pump speed real-time monitoring and real-time waveform display systems, and also set up automatic alarm system; and finally, the use of serial debugging serial communication between PC, the design of the monitoring system of cardiac circulatory support device of the prototype with load testing,.Experimental results show that the monitoring system design meets the design requirements,protection monitoring system more comprehensive, and the blood pump is stable, to achieve the desired experiment effect. The monitoring system used for preliminary studies of cardiac assist devices, provides a good platform for the control and structural optimization algorithm subsequent cardiac assist device.
