Study On Automatic Blood Rheology Detector System

People have came to know that their health must be paid more attention to, however,cardiovascular disease, cerebrovascular disease, diabetes, cancer and other diseases become the major diseases that threaten human health. All the diseases above could lead to the variation of blood rheology related indexes. The detection of blood rheology related indexes can provide vital information to the early diagnosis and treatment of these diseases.Blood rheology detector is a kind of main instrument to measure the blood rheology related indexes. The detector which based on blood rheology basic principle has acquired the related indexes by detecting human blood viscosity. This paper has studied the laminae viscosity testing method and implemented the automatic blood rheology indexes detection.This paper has included as following aspects:1) Studying blood rheology detection principle and giving the algorithm of Laminae-type blood rheology detector characteristics parameters based on blood rheology theory.2) Designing 4 level speed detection Laminae-type blood viscosity detection scheme according to the relationship between blood rheology and viscosity. This scheme could measure the high shear blood viscosity, middle shear blood viscosity, low shear blood viscosity and plasma viscosity by controlling the laminae speed.3) Designing automatic sampling, automatic detection, automatic cleaning and other control system hardware circuit and software program.4) Because of the single data detection error, designing data detection algorithm software to reduce the error caused by blood flow changing.5) Combined blood flow detection methods and data detection algorithm, presenting the algorithm of blood rheology detector characteristics parameters.Automatic blood rheology detector could achieve up to 20 per blood sample auto-detection to achieve unattended work environment.
