Abstract

The invention discloses a sphygmomanometer testing device capable of simulating a blood pressure signal emitted by the human body. The device comprises an airbag device, an extrusion assembly in contact connection with the airbag device, a stepping motor connected to the extrusion assembly, a driving circuit connected to the stepping motor and an MCU controller connected to the driving circuit which are all arranged in a sphygmomanometer testing device body; the airbag device is used for generating an simulated airflow adjustable in amplitude and frequency and enabling a sphygmomanometer to detect and input demanded pulsating flow in order to simulate and generate a blood pressure pulse signal of the human body; the MCU controller is used for generating a control signal according to a specified blood pressure adjustment signal and controlling the driving circuit to drive the stepping motor to extrude the airbag device in order to generate the simulated airflow adjustable in amplitude and frequency, and thus the sphygmomanometer can detect and input the demanded pulsating flow. The provided sphygmomanometer testing device can truly and accurately simulate the blood pressure signal of the human body and accurately detect the accuracy of the sphygmomanometer.

Description

technical field [0001] The invention relates to the field of medical equipment, in particular to a sphygmomanometer testing device that imitates a human body to emit blood pressure signals. Background technique [0002] The sphygmomanometer is an instrument used to measure the blood pressure of the human body. With the development of electronic technology, the sphygmomanometer becomes more and more portable. Various portable sphygmomanometers are convenient for users to carry. [0003] The general measurement principle of the sphygmomanometer is: first, tie the cuff on the arm, inflate the cuff automatically, stop pressurizing after reaching a certain pressure (generally 30~50 mmHg higher than the systolic blood pressure), and start deflation. To a certain extent, the blood flow can pass through the blood vessel, and there is a certain oscillation wave, which propagates through the trachea to the pressure sensor, and the pressure sensor can detect the pressure and fluctuatio...
