多参数监护仪扫描速度误差检定分析数据

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。 检定分析得出的扫描速度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。将监护仪扫描速度设置为25mm/s，模拟仪输出频率为2HZ，幅度为1mVde 标准的方波信号到监护仪，在显示波形中，测量4个完整周期波形对应的显示宽度。扫描速度按照以下公式计算：Vs=L/t ，扫描速度误差按照以下公式计算：&=（V0-VS）/VS*100%。Vs为扫描速度，L为4个完整周期波形对应的显示宽度，t为4个完整周期波形对应的时间，t=2s。 &为扫描速度误差。V0为扫描速度设定值，

Multi-parameter monitors are instruments that perform real-time detection and recording of multiple vital sign parameters of patients. The scanning speed error obtained through verification and analysis can be used to evaluate the measurement accuracy of blood pressure parameters of multi-parameter monitors, which helps to assess the overall quality of multi-parameter monitors on the market, and provides reference and technical support for government supervision and medical institutions' procurement.

Set the scanning speed of the monitor to 25 mm/s, and input a standard square wave signal with an output frequency of 2 Hz and an amplitude of 1 mV from the simulator to the monitor. Then measure the display width corresponding to 4 complete cycles of the waveform from the displayed output.

The scanning speed is calculated via the following formula:
$V_s = L / t$
The scanning speed error is calculated via the following formula:
$delta = frac{V_0 - V_s}{V_s} imes 100\%$
Where $V_s$ denotes the scanning speed, $L$ is the display width corresponding to 4 complete waveform cycles, $t$ is the time corresponding to 4 complete waveform cycles with $t = 2s$, $delta$ is the scanning speed error, and $V_0$ is the preset value of the scanning speed.
