摘要
为了满足有源植入式医疗器械标准中静磁场试验要求,研制了一款静磁场抗扰度试验装置.在输入电流约4.75 A条件下,该装置的磁通密度可以达到50 mT,且试验均匀域的磁通密度均匀性偏差达到2.8%.在0.055～50 mT范围内,磁通密度的线性度达到了0.6%.该装置还可以实现对电压、电流、时间、温度以及电磁场曝露等参数进行有效地监控.该研究为有源植入式医疗器械的静磁场抗扰度试验提供了理论和技术支撑.
Abstract
A static magnetic field immunity test device has been developed to meet the requirements of active implantable medical device.50 mT magnetic flux density can achieved undrer 4.75 A input current,with a flux density uniformity of 2.8%.The linearity of the magnetic flux density was 0.6%between 0.055-50 mT.Some important parameters of the device is monitored,such as voltage,current,time,temperature and electromagnetic field exposure.It may provide some theoretical and technical support for the static magnetic field immunity test of active implantable medical devices.
