Description

Technical Field

[0001] This utility model belongs to the technical field of medical imaging auxiliary tools, specifically relating to a medical imaging auxiliary device. Background Technology

[0002] Medical contrast imaging is a routine medical imaging technique in medical imaging examinations. Specifically, it involves introducing a contrast agent into the human body to make organs or tissues that are not easily visible in imaging examinations become clearly visible, thus assisting doctors in diagnosing diseased organs or tissues. Medical contrast imaging examinations generally use protective tools to assist in the completion of the examination, such as lead screens. Lead screens are composed of lead plates and aluminum alloy frames. The lead plates are used to absorb and scatter X-rays and other types of radiation, thereby blocking the radiation generated during medical contrast imaging examinations.

[0003] Lead screens are a common protective device used in medical imaging. After long-term use, the lead plates may wear, crack, break, age, or corrode, resulting in reduced protective performance. The lead plates are usually fixed to the outer aluminum alloy frame by welding or multiple screws. The disassembly and replacement of the lead plates are relatively complicated, and it is not convenient to replace the lead plates that are damaged or cracked, which has its shortcomings.

[0004] When the lead plates of existing lead screens are damaged or cracked and need to be replaced, there is a problem that there is no convenient assembly design for replacing the damaged lead plates. To address this, this application proposes a medical imaging auxiliary device. Utility Model Content

[0027] Please see Figures 1 to 7 This utility model provides a technical solution: a medical imaging auxiliary device, including a lead plate screen assembly, comprising a combined outer frame 1 and an inner lead plate 2. The outer frame 1 and the inner lead plate 2 are of a separate structure, facilitating the replacement of a damaged inner lead plate 2. Symmetrically distributed insertion rods 21 are provided on the bottom of the inner lead plate 2, and the insertion rods 21 are welded to the inner lead plate 2. A positioning hole 11 is provided on the surface of the bottom end of the outer frame 1. When the outer frame 1 and the inner lead plate 2 are combined, the insertion rods 21 are inserted into the positioning hole 11 to position the insertion rods 21 and prevent the inner lead plate 2 from tilting. The limiting assembly includes a top rod 3 fixedly connected to the inner lead plate 2, a fixing plate 6 vertically connected to the top rod 3, and a spring plate installed inside the outer frame 1. 5. The spring plate 5 includes an integrally cast stabilizing plate 51, a clamping plate 52, and an extension plate 53. The top rod 3 is welded to the inner lead plate 2. When the inner lead plate 2 is vertically installed inside the outer frame 1 from top to bottom, the fixing plate 6 on the top rod 3 is inserted into the interior of the outer frame 1. The fixing plate 6 is inserted into the position between the corresponding spring plates 5. The spring plate 5 is supported by spring steel material and has elasticity. The spring plate 5 clamps the fixing plate 6. There is friction between the spring plate 5 and the fixing plate 6, which makes the fixing plate 6 installed stably. The top of the clamping plate 52 and the extension plate 53 are both welded with guide plates 54. The guide plates 54 play the role of guiding the fixing plate 6, so that the fixing plate 6 is located between the opposing spring plates 5.

[0028] The locking assembly includes a fixing block 7 welded to the bottom outer surface of the fixing plate 6 and a locking rod 4 that slides through the top rod 3. When the outer frame 1 and the inner lead plate 2 are combined, the locking rod 4 passes through the end of the top rod 3, and the bottom end of the locking rod 4 is inserted into the interior of the fixing block 7. The locking rod 4 limits the top rod 3, so that the outer frame 1 and the inner lead plate 2 remain stable.

[0029] In this embodiment, the outer frame 1 and the top rod 3 form a support frame for limiting the inner lead plate 2. The inner lead plate 2 is installed inside the support frame. The insertion rod 21 cooperates with the corresponding positioning hole 11. The insertion rod 21 is inserted into the positioning hole 11 and is limited. The outer frame 1 has a "U" shaped structure. The top of the outer frame 1 is flush with the top surface of the inner lead plate 2. The bottom surface of the top rod 3 is flush with the top surface of the outer frame 1. The top rod 3 has a through hole 31 for the locking rod 4 to pass through. The locking rod 4 passes through the end of the top rod 3 and limits the top rod 3.

[0030] In this embodiment, the fixing block 7 has a screw hole through which the bottom end of the locking rod 4 passes. The top end of the locking rod 4 has a "T" shaped structure, and the outer surface of the bottom end of the locking rod 4 has an external thread. The bottom end of the locking rod 4 is inserted into the interior of the fixing block 7. The locking rod 4 and the fixing block 7 are connected by screw thread. The locking rod 4 limits the top rod 3, so that the outer frame 1 and the inner lead plate 2 remain stable.

[0031] In this embodiment, the three-dimensional fixing plate 6 is an isosceles triangle with an open edge on one side. The fixing plate 6 includes a middle plate c and symmetrically distributed waist plates d. The intersecting sides of the symmetrical waist plates d are open. The waist plates d of the fixing plate 6 are attached to the corresponding clamping plates 52. The clamping plates 52 are in an inclined state. When the inner lead plate 2 is installed, the top rod 3 moves with the inner lead plate 2. The fixing plate 6 on the top rod 3 is inserted into the position between the corresponding spring plates 5. The spring plates 5 clamp the fixing plate 6 to keep it stable.

[0032] In this embodiment, the stabilizing plate 51 is perpendicular to the inner surface of the outer frame 1. The two ends of the clamping plate 52 are connected to the stabilizing plate 51 and the extension plate 53 respectively. The gap between the opposing clamping plates 52 is the mounting groove. The fixing plate 6 cooperates with the mounting groove. When the inner lead plate 2 is removed, the locking rod 4 is rotated to loosen it. The corner of the top rod 3 has a notch. The locking rod 4 passes through the notch and is inserted into the inside of the side of the outer frame 1. The locking rod 4 abuts against the extension plate 53 of the spring plate 5, so that there is a gap between the spring plate 5 and the fixing plate 6, which facilitates the movement of the fixing plate 6 and makes it easy to remove the top rod 3.

[0033] Working principle and usage process of this utility model:

[0034] When the outer frame 1 and the inner lead plate 2 are combined, the inner lead plate 2 is vertically installed inside the outer frame 1 from top to bottom; the top rod 3 moves with the inner lead plate 2, and the fixing plate 6 on the top rod 3 is inserted into the position between the corresponding spring plates 5. The spring plates 5 clamp the fixing plate 6 to keep it stable.

[0035] The inner lead plate 2 is attached to the outer frame 1, and the insertion rod 21 is inserted into the positioning hole 11 to position the insertion rod 21 and prevent the inner lead plate 2 from tilting.

[0036] The bottom end of the locking rod 4 is inserted into the interior of the fixing block 7. The locking rod 4 and the fixing block 7 are connected by a threaded connection. The locking rod 4 limits the top rod 3, so that the outer frame 1 and the inner lead plate 2 remain stable.

[0037] When removing the inner lead plate 2, rotate to loosen the locking rod 4 and remove the locking rod 4;

[0038] The top rod 3 has a notch at the corner. The locking rod 4 passes through the notch and is inserted into the inside of the side of the outer frame 1. The locking rod 4 abuts against the extension plate 53 of the spring plate 5, so that there is a gap between the spring plate 5 and the fixed plate 6, which facilitates the movement of the fixed plate 6, making it easy to remove the top rod 3 and the inner lead plate 2 for replacement.

[0039] In summary: The lead screen has an assembly design that facilitates the replacement of damaged lead plates. The outer frame 1 and the inner lead plate 2 are combined. When installing the outer frame 1 and the inner lead plate 2, the fixing plate 6 is inserted between the corresponding spring plates 5, and the bottom end of the locking rod 4 is screwed into the interior of the fixing block 7. The locking rod 4 limits the top rod 3, so that the outer frame 1 and the inner lead plate 2 remain stable. The connection method between the outer frame 1 and the inner lead plate 2 is simple and facilitates the disassembly and assembly of the inner lead plate 2.
