摘要
人工耳蜗植入体在磁共振设备扫描下会产生非预期的电荷和电流,这些非预期输出会给植入者带来不同程度的伤害。YY0989.7-2017是人工耳蜗植入系统的专用要求,其对具有磁共振兼容功能的人工耳蜗植入体在核磁共振扫描下的非预期输出进行了规定。文章对影响非预期输出测试结果的因素进行分析,并给出对应的注意事项和解决方法。
Cochlear implants will generate unintentional charges and currents during MRI scanning.These unexpected outputs will cause patient harm of varying severity.YY0989.7-2017 is a special requirement of cochlear implant system,which specifies the unintentional output of cochlear implants with MRI safe under MRI scan.The influencing factors of the unintentional output test results were analyzed,and the corresponding precautions and solutions are given.
