Design Of Remote Blood Pressure Monitoring System Based On Virtual Instrument

Blood pressure is the flow of blood in the blood vessels the pressure against the vessel wall. If the pressure exceeds the normal range, it will cause hypertension. With the continuous development of society, people’s living standard is improving, especially dietary patterns and other lifestyle changes, causes our country hypertension patients showing a rising trend, at present in our country the proportion of patients as high as20%, and each year will increase at the speed of10000000. Hypertension is the most important risk factors of cardiovascular and cerebra vascular disease,can cause stroke, myocardial infarction, heart failure and chronic kidney disease. The domestic and international practice prove, early detection is the key to the prevention and treatment of hypertension.Based on the community clinics and family patterns of community heal th care is a health care reform mode in recent years vigorously advocate d by China. This research is based on this, in the case of patients rema in within doors.developed a set of remote blood pressure monitoring sys tem, so as to grasp the patient information, timely treatment, risk so a s to reduce complications of hypertension. Through this system, the pati ent can self measurement of blood pressure at home, and the results of r eal-time online transfer to the doctor, professional guidance from docto rs.Through analysis and research, the domestic and international modern medical monitoring system, using the LabVIEW platform for the developme nt of remote blood pressure monitoring system based on virtual instrumen t.This paper firstly introduces the definition of hypertension, comp a re several common methods of measuring blood pressure, ultimately determ ine the oscillometric method is the most suitable for electronic sphygmo manometer.Secondly, the hardware circuit system, with the sensing chip and the control chip as the core, the acquisition system is divided into seven p arts:signal acquisition, filtering, A/D conversion part, discharging par t, display part, a storage part and communication part.Finally, for processing and remote transmission of blood pressure sig nal, variable technique realized by LabVIEW sharing.When this system completed, I try to explore experimental teaching, v irtual instrument and experiment teaching by combining the advantages br ought by.The system has been basically has the function of remote physiologica1parameters collection, analysis, transmission, has certain use value.
