4 Overview

Multi-parameter physiological simulator is mainly used for multi-parameter patient quality control and technical training monitor can output sine Wave, square wave and triangular wave reference waveform, and can simulate human ECG, respiration, invasive blood pressure, cardiac output, body temperature and many other electrophysiological parameters. Various waveforms required by the digital to analog converter and physiological signals generated by the input signal amplitude and frequency Into the digital control. ECG signal generated by the microcontroller control DAC, via a resistor network attenuated by a guide Union Distribution network output; analog signals through analog breathing respiratory impedance changes, with ECG output; blood pressure Analog signal generated by the resistive bridge sensors, and the applied voltage is proportional to the excitation; cardiac output analog signals using heat the relationship between resistance and temperature-sensitive indirect simulation; analog temperature thermistor resistance value at a specified temperature Simulation.
