基于时基集成电路的医用电气设备剩余电压试验工装电路的设计与实现

The Design and Implementation of the Device Circuit for Medical Electrical Equipment Residual Voltage Test Based on Time Base Integrated Circuit

医用电气设备电源部分的干扰抑制电容过大,储存的能量有可能会对操作者造成伤害,GB 9706.1-2007《医用电气设备第1部分:安全通用要求》中要求对于干扰抑制电器超过限值的医用电气设备需要进行剩余电压试验,文章主要通过基于时基集成电路的医用电气设备剩余电压试验工装电路进行设计与实现,并提供校准方法以使该电路满足标准要求。

If the power supply interference suppression capacitors of medical electrical equipment stored large energy, it may be damage the operator. The standard GB 9706.1-2007 Medical electrical equipment-part 1： General requirements for safety requires the residual voltage test for the medical electrical equipment which interference suppression capacitors exceed the limit. This paper discuss the design and implementation of the device circuit for medical electrical equipment residual voltage test based on time base integrated circuit and provides a calibration method to make the circuit to meet the standard requirement.
