Abstract
Description
Technical Field
[0001] This utility model belongs to the field of medical device technology, and in particular relates to a nuclear medicine isolation screen. Background Technology
[0002] Nuclear medicine is an emerging discipline that uses nuclear technology to diagnose, treat, and study diseases. It is a product of the combination of modern science and technology such as nuclear technology, electronic technology, computer technology, chemistry, physics, and biology with medicine. Currently, nuclear medicine shielding is used to block nuclear radiation during nuclear medicine examinations.
[0003] However, because existing nuclear radiation isolation barriers have wheels installed at the bottom, gaps can lead to nuclear radiation leakage. In addition, most existing isolation barriers are flat and can only be spliced in straight lines, making it inconvenient to splice multiple isolation barriers into multiple shapes to form isolation zones. When spliced at right angles, gaps are easily generated, which can cause nuclear radiation leakage. Utility Model Content
[0004] The purpose of this invention is to provide a nuclear medicine isolation screen to solve the technical problems mentioned in the background art.
[0005] To achieve the above objectives, the specific technical solution of this utility model is as follows: A nuclear medicine isolation screen includes an isolation plate. The front, rear, and right side walls of the right end of the isolation plate are respectively provided with a front slot, a rear slot, and a right slot. The left end of the isolation plate is provided with an insert strip, and the top ends of two adjacent isolation plates are connected by a fixing member. The bottom front and rear sides of the isolation plate are provided with retractable moving mechanisms. The moving mechanism includes a U-shaped seat. The bottom middle part of the horizontal section of the U-shaped seat is provided with a groove. A bidirectional lead screw is rotatably connected to the groove through a bearing. One end of the U-shaped seat is provided with a motor. The shaft of the motor is connected to the bidirectional lead screw, and two symmetrically distributed threaded blocks are threadedly connected to the bidirectional lead screw. The bottom of the threaded blocks is rotatably connected to a connecting rod through a rotating shaft. The bottom of the connecting rod is rotatably connected to a connecting seat through a rotating shaft. The bottom of the connecting seat is equipped with a moving wheel.
[0006] Preferably, the front card slot, rear card slot, and right card slot are all open structures at the top and bottom, and the dimensions of the insert strip all match the dimensions of the front card slot, rear card slot, and right card slot.
[0007] Preferably, the upper surface of the isolation plate is provided with a left insertion hole and a right insertion hole at its left and right ends, respectively.
[0008] Preferably, the fastener includes a connecting piece, and each end of the connecting piece is provided with a post at its bottom, the size of which matches the size of the left and right insertion holes.
[0009] Preferably, the two vertical sections of the U-shaped seat are provided with vertically distributed limiting grooves on opposite sides, and the side wall of the connecting seat is provided with a limiting block that slides vertically and vertically connected with the limiting groove.
[0010] Preferably, a battery box is provided on one side of the upper surface of the U-shaped seat, a battery is provided inside the battery box, and a charging port is provided on the battery box.
[0011] The nuclear medicine isolation barrier of this utility model has the following advantages:
[0012] 1. This utility model allows for the splicing and assembly of multiple isolation panels through the cooperation between the insert strip and the front, rear, and right slots. This enables multiple isolation panels to be spliced into multiple different shapes to form isolation zones, greatly improving the flexibility and utilization rate of the isolation screen. Furthermore, by inserting the insert strip into the slots, the connection between the isolation panels becomes tighter, improving the isolation effect.
[0013] 2. This utility model, through the cooperation between the limiting block and the limiting groove, provides a good limiting effect for the connecting seat. When the motor is started, the bidirectional lead screw rotates, causing the two threaded blocks to move in opposite directions simultaneously. Under the action of the connecting rod, and in cooperation with the limiting block and the limiting groove, the connecting seat can drive the moving wheel to move up or down. When it is necessary to move the isolation plate, the moving wheel moves downward, causing the bottom of the isolation plate to detach from the ground, allowing the isolation plate to be moved by the moving wheel. When it is not necessary to move the isolation plate, the moving wheel is raised, at which point the bottom of the isolation plate will be in close contact with the ground, preventing the radiation source from overflowing from the bottom and further improving the stability of the isolation.

[0026] To better understand the purpose, structure and function of the present utility model, the following further describes in detail a nuclear medicine isolation screen of the present utility model with reference to the accompanying drawings.
[0027] As Figure 1-5 shown, a nuclear medicine isolation screen of the present utility model includes an isolation board 1. Front, rear and right side walls at the right end of the isolation board 1 are respectively provided with a front slot 8, a rear slot 3 and a right slot 9. An insertion strip 10 is provided at the left end of the isolation board 1. The front slot 8, the rear slot 3 and the right slot 9 are all of an up-and-down open structure, and the size of the insertion strip 10 matches the size of the front slot 8, the rear slot 3 and the right slot 9. Through the cooperation between the insertion strip 10 and the front slot 8, the rear slot 3 and the right slot 9, multiple isolation boards 1 can be spliced and assembled, and multiple isolation boards 1 can be surrounded into shapes such as "□", "凵", "_", etc., greatly improving the flexibility of the isolation screen and the utilization rate. Moreover, by inserting the insertion strip 10 into the slot, the connection between the isolation boards 1 is made closer, improving the isolation effect.
[0028] The tops of two adjacent isolation boards 1 are connected by a fixing member. Left and right ends of the upper surface of the isolation board 1 are respectively provided with a left insertion hole 4 and a right insertion hole 5. The fixing member includes a connecting piece 6. Bottoms of both ends of the connecting piece 6 are provided with insertion posts 7. The size of the insertion posts 7 matches the size of the left insertion hole 4 and the right insertion hole 5. When two isolation boards 1 are butted, the distance between the left insertion hole 4 and the right insertion hole 5 on the two isolation boards 1 is equal to the distance between the two insertion posts 7, so that the two insertion posts 7 on the connecting piece 6 can be respectively inserted into the left insertion hole 4 and the right insertion hole 5, thereby firmly fixing the two isolation boards 1 together by the fixing member, and the operation is simple and fast.
[0029] The bottom of the isolation plate 1 is provided with retractable moving mechanisms 2 on both the front and rear sides. The moving mechanism 2 includes a U-shaped seat 11. The bottom middle part of the horizontal section of the U-shaped seat 11 is provided with a groove 13. A double-acting screw 14 is rotatably connected to the groove 13 through a bearing. A motor 15 is provided at one end of the U-shaped seat 11. The shaft of the motor 15 is connected to the double-acting screw 14. Two symmetrically distributed threaded blocks are threaded on the double-acting screw 14. The bottom of the threaded blocks is rotatably connected to a connecting rod 16 through a rotating shaft. The bottom of the connecting rod 16 is rotatably connected to a connecting seat 17 through a rotating shaft. A moving wheel 18 is installed at the bottom of the connecting seat 17. The U-shaped seat 11 has vertically distributed limiting grooves 20 on each of its two vertical sections. The side wall of the connecting seat 17 has a limiting block 19 that slides vertically and vertically with the limiting groove 20. Through the cooperation between the limiting block 19 and the limiting groove 20, the connecting seat 17 is effectively limited. When the motor 15 is started, the bidirectional lead screw 14 rotates, causing the two threaded blocks to move in opposite directions simultaneously. Under the action of the connecting rod 16, and in cooperation with the limiting block 19 and the limiting groove 20, the connecting seat 17 can drive the moving wheel 18 to move up or down. When it is necessary to move the isolation plate 1, the moving wheel 18 moves downward, so that the bottom of the isolation plate 1 is separated from the ground. The isolation plate 1 can then be moved by the moving wheel 18. When it is not necessary to move the isolation plate 1, the moving wheel 18 is raised. At this time, the bottom of the isolation plate 1 will be in close contact with the ground, preventing the radiation source from overflowing from the bottom and further improving the stability of the isolation. A battery box 12 is provided on one side of the upper surface of the U-shaped base 11. The battery box 12 contains a battery and has a charging port. The battery is used to power the motor 15 and can be charged through the charging port.
