Description
Technical field
The invention belongs to technical field of medical equipment, particularly relate to a kind of MR magnet shield preventer.
Background technology
MR checks namely magnetic resonance examination, is widely used in modern medical imaging inspection diagnosis, and MR checks expensive, and the magnetic field that the capital equipment magnet itself used by imaging inspection produces is more than 40,000 times of magnetic field of the earth.Simultaneously installation environment is required very high by MR, the slight change in any magnetic field of the earth, even if even there being around MR machine room vehicle travels to be all enough to MR is checked and produce impact, all adopts magnetic shield protective material to carry out omnibearing stereo formula external shield protection for this machine room.But, any people doing MR inspection both knows about, patient and accompany people to include stretcher that patient uses, sick bed, wheelchair etc. all must not enter machine room with the article of metal, even if various magnetic cards entrained with them, key, belt etc. are also forbidden being carried along into machine room.Visible, metal class and article easily affected by magnetic fields are exactly almost a forbidden area by MR machine room.One of purpose so required is to prevent MR magnet originally in contingency when, some metal objects moments are produced powerful captivation, make these objects that should not enter machine room itself be attracted to a magnet with the speed of " darting ", clash into magnet and cause the damage of management devices；The two of purpose, owing to MR magnets magnetic fields is powerful, it is possible to the various magnetic cards close to it are carried out moment demagnetization, brings loss to card holder.Above-mentioned two situations all have generation in real work.Therefore, it is extremely important that the generation how avoiding above-mentioned situation just shows.But, how MR magnet itself is protected, has both been avoided that magnet itself comes to harm, be avoided that again the object close to it is affected by the magnetic field of magnet.We design and have invented MR magnet shield preventer, effectively solve this problem.
Summary of the invention
It is an object of the invention to provide a kind of MR magnet shield preventer, realize the purpose of the present invention to be adopted the technical scheme that: a kind of MR magnet shield preventer, it is characterized in that: its agent structure of this screen protective device is made up of shielding protection body, shielding protection body is provided with two corresponding with the touch operation screen of MR gantry can push-and-pull face-port, the middle part of shielding protection body is provided with scanning bed manhole appendix, shielding protection body external shield connecting device is arranged below, both sides below shielding protection body are respectively provided with bracing frame, bracing frame shifting roller is arranged below.
External magnetic field produced by magnet is shielded by the present invention to greatest extent, internal magnetic field magnet not produced in scanner field again constitutes interference, ensure checking on the quality of MR, root, exchange optimum protective shielding effect for by minimum cost, solve the hidden danger existed checking from MR to greatest extent.

In figure, 1, shielding protection body, 2, face-port, 3, scanning bed manhole appendix, 4, external shield connecting device, 5, bracing frame, 6, shifting roller, 7, the scanning bed mobile bed board of MR, 8, the scanning bed pedestal of MR.
Detailed description of the invention
With reference to accompanying drawing, a kind of MR magnet shield preventer, it is characterized in that: its agent structure of this screen protective device is made up of shielding protection body 1, shielding protection body 1 is provided with two corresponding with the touch operation screen of MR gantry can push-and-pull face-port 2, the middle part of shielding protection body 1 is provided with scanning bed manhole appendix 3, shielding protection body 1 external shield connecting device 4 that external shield with machine room be connected is arranged below, both sides below shielding protection body 1 are respectively provided with bracing frame 5, bracing frame 5 shifting roller 6 is arranged below.It is anterior that this MR magnet shield preventer is positioned at MR magnet, wherein, shielding protection body 1 main body is made up of the magnetic shielding material that can shield the strong magnetic field that MR magnet produces, shielding protection body 1 borrows the external shield net of external shield connecting device 4 and MR scanning room to be connected to form magnetic shield loop, produces good shield effectiveness.Shielding protection body 1 is provided with the scanning bed manhole appendix 3 facilitating scanning bed turnover.Generally, MR magnet shield preventer need not move, and once needs machine maintenance, removable external shield connecting device 4, utilize bracing frame 5 and shifting roller 6 to be removed by MR magnet shield preventer.In above-mentioned design, bracing frame 5 is two and is positioned at two ends bottom MR magnet shield preventer, has balance and prevents preventer from toppling over effect.MR magnet shield preventer agent structure adopts antimagnetic material such as copper mesh or copper coin that magnetic field has good shielding action to constitute.
MR magnet shield preventer of the present invention compensate for the deficiencies in the prior art, reasonable in design, simple in construction, it is easy to processing, easy to use, applies respond well.It it is a kind of desirably MR magnet shield protection special equipment.There is good application value.
