Magnetic resonance compatible infusion system based on Faraday cage

Abstract

The invention provides a magnetic resonance compatible infusion system based on a Faraday cage. The magnetic resonance compatible infusion system based on a Faraday cage is used for carrying out infusion in a magnetic resonance strong magnetic field environment, and includes a support module, a Faraday cage shielding module, and an infusion and injection module, wherein the support module is usedto support the Faraday cage shielding module and the infusion and injection module; the Faraday cage shielding module is used for shielding the electromagnetic interference between a magnetic resonance apparatus and the infusion and injection module in the magnetic resonance strong magnetic field environment; the infusion and injection module comprises an infusion and injection tube, an infusion pump and a syringe pump; the materials of the support module includes a non-magnetic material; and the materials of the Faraday cage shielding module includes a non-magnetic metal material. The magnetic resonance compatible infusion system based on a Faraday cage isolates the infusion system from the magnetic resonance strong magnetic field environment by using the Faraday cage shielding module ofthe non-magnetic metal material and the support module of the non-magnetic material, so as to prevent the electromagnetic interference between the infusion and injection module and the magnetic resonance apparatus, and finally, a patient can perform the infusion operation while performing nuclear magnetic scanning under the magnetic resonance strong magnetic field environment.

Description

technical field [0001] The invention belongs to the technical field of medical devices, and in particular relates to a magnetic resonance compatible infusion system based on a Faraday cage. Background technique [0002] During the MRI scan, the patient will sometimes need to be given fluids. For example, some groups without self-control ability, MRI diagnosis of cardiovascular system, surgical treatment under MRI environment, MRI-guided interventional therapy or first aid process in NMR room, etc. [0003] If the infusion system is placed in the MRI room, there will be mutual influence between the infusion system and the MRI equipment. Therefore, if you want to infuse a patient at present, you need to wait for the patient to be stable, and then perform the infusion after the MRI scan process is over, or place the infusion pump and syringe pump outside the MRI room, and provide the patient in the MRI room with an extension tube. Infusion. However, the above methods will de...
