一、概述 标准心率信号发生器是按照JJG760-1991《心电监护仪》国家计量检定规程的要求开发生产的一种计量标准仪器,它在计算机的控制下产生低频率、小幅度、脉冲宽度恒定的标准心率信号,用于检定医用心电监护仪的心率示值误差、心率报警发生时间等技术指标。本文根据JJF1059-1999《测量不确定度评定与表示》,对标准心率信号发生器心率误差和输出幅度误差的测量不确定度分别进行了分析和评定。
First, an overview Standard heart rate signal generator is in accordance with the JJG760-1991 “ECG” National Metrology test requirements developed and produced a measurement standard instrument, which under the control of the computer to produce low-frequency, small amplitude, constant pulse width The standard heart rate signal is used to test the medical heart rate monitor heart rate error, heart rate alarm time and other technical indicators. According to JJF1059-1999 Evaluation and Expression of Measurement Uncertainty, the measurement uncertainty of the standard heart rate signal generator heart rate error and output amplitude error are respectively analyzed and evaluated.
