一种核磁共振成像中微量注射泵防磁屏蔽箱的设计
Designs of Antimagnetic Shield Box to Use Micro Injection Pump in Magnetic Resonance Image Formation
摘要
Abstract
Objective To design one kind of antimagnetic shield box which is able to use the micro injection pump's in the MR1 strong magnetic field environment. Methods With electromagnetic screen mechanism, ihe non -ferromagnetic material was used to process the cuboid box. Whose size was proper to contain a conventional micro injection pump. Protective measures were taken to the operation hole, infusion connecting pipe and the seam beside the door, ihus enabling it to be antimagnetie and isolated. Results This method avoided the conventional MR1 magnetic field on the magnetization of the role of micro-injection pump, and the MRI image quality were not affected. Conclusion In the MRI environment, this antimagnelic shield box can cause the conventional micro injection pump to use normally under the effective addressing MRI environment, which solve the problem of inaccurate medicine given by manpower. It also expands the use scope of conventional micro injection pump, and enhances the working efficiency as well as saves the massive manpower and themedical resources.关键词
