BRIEF DESCRIPTION OF THE DRAWINGS

[0013] Figure 1 This is a schematic diagram of the structure of Example 1 of the present invention;

[0014] Figure 2 This is a schematic diagram of the structure of Example 3 of the present invention. DETAILED DESCRIPTION

[0015] The principles and features of the present invention are described below. The examples given are only used to explain the present invention and are not used to limit the scope of the present invention.

[0016] Example 1

[0017] like Figure 1 As shown, a nuclear magnetic resonance protective shield includes an antibacterial cleaning layer 1, a basic tensile layer 2 and an anti-puncture layer 3, wherein the basic tensile layer 2 is located in the middle layer, and the antibacterial cleaning layer 1 and the anti-puncture layer 3 are located in the outer layer of the basic tensile layer 2, the antibacterial cleaning layer 1 is made of an antibacterial non-woven fabric material, the basic tensile layer 2 is made of a mesh cloth material, and the anti-puncture layer 3 is made of a woven fabric material. Among them, the woven fabric is a polyethylene fiber woven fabric, and the mesh cloth is a PP polypropylene woven fabric. The antibacterial cleaning layer 1, the basic tensile layer 2 and the adjacent layers of the puncture layer 3 are bonded and connected by pasting. In this embodiment, chemical adhesives can be used for bonding, such as water-based polyurethane bonding, which has strong viscosity and can effectively improve the bonding strength between the layers. The toughness of antibacterial non-woven fabrics, woven fabrics, and PP polypropylene woven fabrics are relatively good, and the toughness is better after strong bonding, which ensures that the entire protective shield structure is firm and prevents puncture from sharp metal objects. In the inspection room, when the MRI machine is working, a magnetic field is generated. The surrounding metal objects will fly towards the MRI machine after being affected by the magnetic field. By setting a protective shield next to the MRI machine, metal objects can be blocked to prevent metal objects from splashing and causing damage to personnel and equipment. The material of the protective shield is made of cloth as a whole, and adopts a non-metallic design. It will not affect the detection method and accuracy of the existing MRI machine, and basically has no impact on the detection efficiency. In addition to the need for regular inspection, the protective shield of the present invention has basically no later loss, low cost of use, safe and reliable, and can resist sharp external forces. For sharp metal objects (keys, pins, hairpins, brooches, etc.) with a flying speed of less than 5m / s, the protective shield will basically not be pierced. The blocking effect of the protective shield is significant, which can ensure that there will be no accidents during the MRI examination.

[0018] In actual use, the surface of the bacteria cleaning layer 1 is facing the direction of the MRI machine, and the surface of the anti-puncture layer 3 is facing the direction of the door. Since a protective shield is added at the door of the examination room, even when the door is not closed, the protective shield can block metal objects flying in from the door. In addition, the protective shield can completely replace the door of the examination room, which can reduce the cost of the examination room as a whole and facilitate entry and exit.

[0019] Example 2

[0020] like Figure 2As shown, a nuclear magnetic resonance protection shield includes an antibacterial cleaning layer 1, a basic tensile layer 2, an anti-puncture layer 3 and an antibacterial cleaning layer 1, which are arranged in sequence. The four corners of the basic tensile layer 2 are fixed with traction ropes. The traction rope is used to fix the entire nuclear magnetic resonance protection shield. The traction rope is generally tied to the wall to ensure that it can withstand a large tensile force in the process of blocking metal objects. The antibacterial cleaning layer 1 is made of antibacterial non-woven fabric material, the basic tensile layer 2 is made of mesh cloth material, and the anti-puncture layer 3 is made of textile fabric material. Among them, the textile fabric is a polyethylene fiber woven fabric, and the mesh cloth is a PP polypropylene woven fabric. The antibacterial cleaning layer 1, the basic tensile layer 2, the anti-puncture layer 3, and the antibacterial cleaning layer 1 are bonded and connected by pasting. In this embodiment, Velcro bonding is used for active bonding connection.

[0021] In summary, the nuclear magnetic resonance protection shield provided by the present invention can block metal objects and prevent metal objects from splashing and causing damage to personnel and equipment. The material of the protection shield is made of cloth as a whole, and adopts a non-metallic design, which will not affect the detection method and accuracy of the existing nuclear magnetic resonance machine, and basically has no effect on the detection efficiency.

[0022] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
