1故障现象打开电源仪器工作正常,血压测量时机器正常充气,但放气速度明显变慢,长时间测量后机器显示测量失败。2故障分析UT4000型监护仪血压测量采用无创振动法测量,其测量原理如图所示:系统微处理器控制充气系统和放气系统,袖带在微处理的控制下得到一稳定的压力,并以固定的速 1 Fault phenomenon Turn on the power The instrument is working properly, the normal pressure when the machine is inflated, but the deflation rate was significantly slower, after a long period of time the measurement showed that the machine failed to measure. 2 Fault Analysis UT4000 monitor blood pressure measurement using non-invasive vibration measurement, the measurement principle shown in Figure: The system microprocessor controls the inflation system and the deflation system, the cuff under the control of the microprocessor to get a steady pressure and With a fixed speed
