Abstract:The traditional quality inspection methods for sphygmomanometer have disadvantages of single function, obsolete technology, low degree of automation and poor precision etc. This paper creatively puts forward the relevant indicators and methods of the sphygmomanometer quality inspection, and based on the theory, an automatic, multifunctional and universal quality inspection system for sphygmomanometer is proposed in the paper. The experimental results show that, these quality inspection indicators can judge the quality state of the bloodpressure meter thoroughly, and the system has functions of gas leak detection, pressure characteristic curve test, power test etc. The system can check the comprehensive characteristics for all kinds of sphygmomanometer products automatically by programming and parameter adjustment.
