摘要
目的结合临床对数字心电图机的应用需求及关注指标,研究制订符合医疗机构应用场景的数字心电图机自主质控检测办法,保障数字心电图机功能,提升计量强检合格率。方法以分析本区质监所近3年数字心电图机强检情况为切入点,结合人工检查和模拟器等检测工具,从仪器外观、日常管理及开机检查、内定标电压误差、输入电压范围、加权系数误差、波形识别能力与幅度-时间参数测量、心电测量误差7个维度进行定性检测及定量检测。结果通过数字心电图机质控检测管理办法,我院数字心电图机的不合格数量从2019年的10台下降至2021年的1台;在确保检测结果有效的基础上,通过简化检测内容及结合质控检测报告对照法的检验方式,使质控检测时长从(43±6)min缩短至(21±4)min(P<0.05)。结论数字心电图机质控工作能发现数字心电图机的运行隐患并前置解决,从而确保设备性能及满足临床诊断需求,为临床精准监测患者生理参数提供有力保障。
Objective To study and formulate the independent quality control and detection method of digital electrocardiograph in line with the application scenario of medical institutions,combined with the clinical application needs and concerned indicators of digital electrocardiograph,to guarantee the function of digital electrocardiogram machine and improve the qualified rate of strong detection of measurement.Methods Taking the analysis of the forced inspection of digital electrocardiograph in the Quality and Technical Supervision and testing institute of the district in recent three years as the starting point,combined with manual inspection,simulator and other detection tools,qualitative detection and quantitative detection were carried out from the seven dimensions of instrument appearance,daily management and startup inspection,internal calibration voltage error,input voltage range,weighting coefficient error,waveform recognition ability and amplitude time parameter measurement,ECG measurement error.Results Through the quality control test management measures of digital electrocardiographs,the number of unqualified digital electrocardiographs in our hospital decreased from 10 in 2019 to 1 in 2021.On the basis of ensuring the effectiveness of the test results,the quality control test time was shortened from(43±6)min to(21±4)min(P<0.05)by simplifying the test content and combining the control test method with the quality control test report.Conclusion The quality control of digital electrocardiograph can find the hidden dangers of digital electrocardiograph and solve them in advance,so as to ensure the performance of the equipment and meet the needs of clinical diagnosis,and provide a strong guarantee for clinical accurate monitoring of patients’physiological parameters.
