Abstract

The invention relates to a systemic circulation model and a method for detecting an electronic sphygmomanometer by using the model. In the model, a vessel unit is used for connecting a heart power unit with an arm-to-be-detected unit to form a closed and circular human body systemic circulation simulation system; the heart power unit provides enough circulation power for the vessel unit and simulates the heartbeat of the human body, and a user sets central artery blood flow volume waveforms of different parameters; the arm-to-be-detected unit simulates and measures a waveform and a pressure value of a circulating system pulse wave; a control unit receives pulse wave data, a man-machine interaction unit is arranged, and the control unit sends control commands to the heart power unit and the arm-to-be-detected unit; the man-machine interaction unit displays the waveform of the pulse wave and a blood pressure value, different parameters are selected and set, and switching among functions is achieved. According to the systemic circulation model, the electronic sphygmomanometer in delivery and long-time using is identified regularly, diagnostic errors can be avoided, a reliable measurement tool is provided for a quality testing unit, and a secondary development platform is also provided for the teaching experiment and scientific research.

Description

technical field [0001] The invention relates to the technical field of verification of an electronic sphygmomanometer, in particular to a systemic circulation model and a method for detecting the electronic sphygmomanometer. Background technique [0002] With the development of social economy, the national lifestyle has undergone profound changes. In particular, the aging population and the acceleration of urbanization have led to a continuous increase in the incidence of cardiovascular diseases. The cardiovascular circulatory system is composed of the heart and blood vessels. The basic condition for the formation of blood pressure is sufficient blood filling in the closed cardiovascular system. Cardiac ejection and peripheral resistance are the two basic factors for the formation of blood pressure. The measurement of blood pressure is to test the lateral pressure of blood on the blood vessel wall, which is an inspection method that reflects the heart function and the elast...
