多参数监护仪电压测量误差检定分析数据
收藏资源简介:
多参数监护仪可以对病人多种生命体征参数进行实时检测和记录的仪器。 检定分析得出的电压测量误差可用来判断多参数监护仪血压的量值准确度,有助于判断市场上多参数监护仪的的整体质量,为政府监管、医疗单位购买提供参考和技术支撑。将监护仪增益设置为10mm/Vm,使心电模拟仪输出电压值为1.0mV,频率为2.0Hz的方波信号到监护仪,计算监护仪所测量到的方波信号电压值Vi,并按照以下公式测算:电压测量误差=(监护仪测量电压值-心电模拟仪输出电压值)/心电模拟仪输出电压值*100%。
Multi-parameter monitors are medical instruments capable of real-time detection and recording of various vital signs parameters of patients. The voltage measurement error obtained through calibration and analysis can be used to evaluate the measurement accuracy of blood pressure parameters of multi-parameter monitors, which helps to judge the overall quality of multi-parameter monitors on the market, and provides reference and technical support for government supervision and medical institution procurement. Set the gain of the monitor to 10 mm/Vm, make the electrocardiogram (ECG) simulator output a square wave signal with an output voltage of 1.0 mV and a frequency of 2.0 Hz to the monitor, calculate the voltage value Vi of the square wave signal measured by the monitor, and calculate the voltage measurement error according to the following formula: Voltage measurement error = [(measured voltage value of the monitor - output voltage value of the ECG simulator) / output voltage value of the ECG simulator] * 100%.
