In order to make the technical means, creation features, achievement purposes and functions of the present invention easy to understand and understand, the present invention is further explained by combining with the specific drawings.

As shown in fig. 1 and 2, the present invention provides a limb isolation device for MRI examination, which includes two arm isolation sleeves 100, two lower limb isolation sleeves 200 and two isolation pads 300. The two arm separating sleeves 100 are oppositely distributed and connected by a first connecting belt 400. Arm spacer sleeve 100 is including the cover body 110, slash pocket 120 and division board 130, the cover body 110 inside wall is equipped with transverse distribution's connection opening 111 to paste through setting up the magic will arm spacer sleeve 100 is fixed with the examinee's arm. The outer side wall of the sheath body 110 is seamed with a plug-in pocket 120, and a separation plate 130 is inserted into the plug-in pocket 120, and the separation plate 130 can be preferably made of plastic or cardboard and other materials, so that the deformation is not easy and the separation state is more convenient to maintain. Two the structure of low limbs spacer 200 with the structure of arm spacer 100 is unanimous to through second connecting band 500 with first connecting band 400 can dismantle the connection, and distribute two one side of arm spacer 100. Two the connection can be dismantled through third connecting band 600 between the isolation pad 300, one of them isolation pad 300 again through third connecting band 600 with first connecting band 400 can dismantle the connection, and distribute two one side of low limbs isolation sleeve 200. The separating pad 300 includes a convex separating portion 310 and two concave placing portions 320, wherein the two concave placing portions 320 are respectively distributed on two sides of the convex separating portion 310 and are integrally formed with the convex separating portion 310.

By adopting the structure, when an MRI examination is carried out, after an examinee lies on an examination bed, the arm is sleeved into the sleeve body 110 from the connecting opening 111 and is fixedly connected by the magic tape. The isolation plate 130 installed in the pocket 120 is located outside the arm, and isolates the upper limb of the subject from the wall of the magnetic resonance chamber. The lower limb separation sleeve 200 having the same structure as the arm separation sleeve 100 is fixed to both legs in the above manner at a position close to the root of the thigh, and the separation plate 130 of the lower limb separation sleeve 200 is positioned outside the body to separate the hands from the thigh. Two separation pads 300 are laid on the subject's knees and ankles, respectively, with the convex separation portion 310 of the separation pad 300 interposed between the legs, and the legs are placed in the concave placement portions 320 on both sides of the convex separation portion 310, respectively, to separate the skin contact at the knees and the skin contact at the ankles of the lower limbs. This isolating device all adopts non-metallic material to make, and the upper limbs that the area occupied is widest are avoided contacting with instrument section of thick bamboo wall, and hand, both knees and ankle are all kept apart the contact, all are kept apart by this isolating device in the limbs position that forms current loop the easiest, reduce the risk that takes place the tissue burn, are particularly suitable for the person of being examined that the domination ability is weaker, for example paralysed, coma etc. are examined the crowd. The lower limb isolation sleeve 200 and the arm isolation sleeve 100 can be disassembled, the isolation pad 300 can be disassembled, and the isolation pad can be selected for use according to actual conditions in the process of being detected, so that the flexibility is higher.

As an optional embodiment, the sheath body 110 is a hollow cylindrical structure, two sides of the connecting opening 111 are respectively sewed with a fixing band 112 with elasticity, and magic tapes matched with each other are arranged on the fixing band 112, so that the fixing band 112 with elasticity can be conveniently used by examinees with different body sizes.

The insert pocket 120 is in a semicircular structure, and the pocket opening is a binding opening with elasticity, so that the fixation of the insert pocket 120 to the partition board 130 inserted therein is enhanced. The inner wall of the insert pocket 120 is provided with a plurality of rubber anti-slip protrusions (not shown), such as a cardboard or a plastic plate, and other materials capable of being isolated, and the interference of the anti-slip protrusions increases the friction force and prevents the rubber anti-slip protrusions from easily falling off and shifting.

The isolation plate 130 includes a plug-in portion 131 and a vertical portion 132, the shape of the plug-in portion 131 matches with the shape of the plug-in pocket 120, and the vertical portion 132 is fixedly connected to one end of the plug-in portion 131 and vertically distributed above the plug-in portion 131. After the insertion part 131 is inserted into the insertion bag 120, the shape of the insertion part and the shape of the insertion bag are matched, so that the arm or thigh is placed in the arc-shaped insertion part 131 after connection, the insertion part 131 is favorable for keeping the state after bearing the load, and the use is not easily influenced by tilting.

The outer side walls of the insert pockets 120 of the two lower limb isolation sleeves 200 are also sewed with a restraint strap 121, and the restraint strap 121 is made of elastic flexible material. After the lower limbs are provided with the upper and lower limb isolation sleeves 200, the hands of the examinees may be attached to the outer wall of the lower limb isolation sleeve 200 during examination, and at the moment, the fingers are inserted into the constraint belt 121 to constrain the fingers to move randomly, so that the fingers are prevented from touching other parts randomly, and the possibility of forming a current loop is still generated.

The convex isolating part 310 is of a convex arc-shaped structure, the concave placing part 320 is of a concave arc-shaped structure, so that two legs can be placed conveniently, and the convex isolating part 310 is arranged between the two legs and higher than the two legs, so that the convex isolating part can be effectively isolated. The strap 330 is disposed from the non-connecting end of the concave placement portion 320 to the top end of the convex isolation portion 310, the strap 330 is made of a flexible material with elasticity, and the strap 330 has a better isolation effect after restraining the foot. For more convenient use, the size of the insulation pad 300 placed at both knees is larger than that of the insulation pad 300 at the ankle position.

First connecting band 400, second connecting band 500 and third connecting band 600 all adopt the cotton to make, second connecting band 500 with all be equipped with on the third connecting band 600 the magic subsides with first connecting band 400 bonds. The cost is saved, the disassembly and the assembly are convenient, and the connection is realized without metal parts, so that the device is more practical.

The above is only the embodiment of the present invention, not the limitation of the patent scope of the present invention, all the equivalent structures made by the contents of the specification and the drawings are directly or indirectly applied to other related technical fields, all the same principle is within the patent protection scope of the present invention.
