Abstract:
This paper introduces the working principle of the blood circle treatment system outside the body. A monitoring instrument of plasma leakage suited for the blood circle treatment system outside the body is developed based on the absorption spectrum experiments of plasma leakage. Photoelectric detection technology and virtual instrumentation are utilized in the development. A series of detecting experiments of waste solution containing plasma with continuously changing concentration show the monitoring system possesses a relatively high sensitivity. Moreover, the experiments of continual detection with plasma concentration at one certain point indicate the monitoring system has a quite good stability. The monitoring instrument is adapted to dynamically detecting the plasma leakage when the blood circle treatment system outside the body is working.
