Differences of microwave therapy equipment in magnetic compatibility radiated emission tests / 国际生物医学工程杂志

ABSTRACT

With the enforcement of YY 0505-2012 standard,more attention has been paid to the electromagnetic compatibility test of medical electrical equipment.In all the test items involved in YY 0505-2012,the radiation emission test is the most complicated and the hardest to be passed,so it is very important to master the test method.Microwave therapy equipment is a kind of equipment using microwave radiation energy to treat diseases,and is supervised as class Ⅲ medical equipment.According to the requirements of the relevant standards,all the electromagnetic compatibility testing items of microwave equipment are listed,and the test difficulty and the test focus of the equipment are studied.In the frequency band of the radiation emission experiment,microwave treatment equipment is divided into different categories according to the purpose and environment of the application.By comparing the data of the tests,the differences of different classes of microwave treatment equipment in the radiation emission tests are summarized.
