Description

Technical Field

[0001] The utility model relates to the technical field of medical devices, in particular to an automatic injection device for radioactive drugs. Background Art

[0002] Radiopharmaceuticals are radionuclide preparations or labeled compounds used for clinical diagnosis or treatment. Radiopharmaceuticals differ from other pharmaceuticals in that they contain radionuclides that emit radiation. Therefore, when administering radiopharmaceuticals, medical personnel must operate under protective equipment.

[0003] Currently, radiopharmaceutical injections must be performed through a dedicated injection window. To protect the operator, the syringe is placed in a shielded container and then connected to the patient's indwelling needle via an injection hose. This operation must be performed behind a protective screen made of lead glass, requiring the operator to reach under the screen to operate. This injection method is not only inconvenient but also exposes the operator, especially the operator's hands, to the radiation environment, leaving the protective effect to be further improved. Therefore, the utility model proposes an automatic radiopharmaceutical injection device. Utility Model Content

The lead top cover 7 and the base 1 serve as protective components to cover the entire automatic injection device, which can effectively shield the radiation of radioactive drugs.

[0024] The closed end of the arc-shaped groove 21 is located near the side of the vertical plate 6. A notch 22 is opened in the middle of the closed end of the support base 2. The injection head of the syringe 4 is located inside the notch 22. The vertical plate 6 is provided with a through hole.

[0025] When the syringe 4 is placed in the arcuate groove 21 , the closed end of the arcuate groove 21 just limits the syringe 4 , making it easier to position the syringe 4 , and the notch 22 is just used to clamp the injection head of the syringe 4 .

[0026] The fixing assembly 3 includes a bracket 31 fixed to the middle portion of the upper surface of the support base 2 , and an extrusion screw 32 passes through and is threadedly connected to the top of the bracket 31 .

[0027] When the syringe 4 is located inside the arc-shaped groove 21 , the syringe 4 can be squeezed and fixed by tightening the squeezing screw 32 .

[0028] At least one visual window 71 is provided on the upper surface of the top cover 7 for observing the injection status of the syringe 4. The visual window 71 is made of lead glass and can block radiation.

[0029] The clamp-type flow sensor 9 is fixedly mounted on the surface of the hose 5. The amount of the medicine flowing through the hose 5 can be monitored by the clamp-type flow sensor 9.

[0030] The driving assembly 8 includes a shell 81 fixed to the upper surface of the base 1, and a horizontal strip-shaped opening 82 is opened on the side of the shell 81 close to the support seat 2, and a slide 83 is slidably connected inside the strip-shaped opening 82. A reduction motor 84 is fixed to the inner wall of the shell 81, and a screw rod 85 is fixedly connected to the driving end of the reduction motor 84. The surface of the screw rod 85 is connected to an internal thread block 86 through a threaded rotation. One end of the slide 83 located inside the shell 81 is fixedly connected to the internal thread block 86, and the end of the slide 83 located outside the shell 81 is in contact with the piston rod of the syringe 4.

[0031] In this embodiment, the reduction motor 84 is a servo motor. When the reduction motor 84 drives the screw 85 to rotate, the screw 85 drives the internal thread block 86 and the slide 83 to move along the strip opening 82. When the slide 83 moves toward the support base 2, it pushes the piston rod of the syringe 4, thereby achieving automatic injection. A PLC control panel is provided on the surface of the housing 81 of the device. The clamp-type flow sensor 9 and the reduction motor 84 are both controlled by the PLC control panel.

[0032] Working principle: First, open the lead top cover 7, place the syringe 4 into the arc-shaped groove 21 on the top of the support base 2, then fix the syringe 4 by tightening the extrusion screw 32, and then pass the hose 5 through the through hole of the vertical plate 6. One end of the hose 5 is connected to the syringe 4, and the other end is connected to the patient's indwelling needle. Then cover the lead top cover 7, and then set the injection volume through the PLC control panel. The reduction motor 84 drives the slide 83 to move, and the slide 83 pushes the piston rod of the syringe 4 to move, thereby squeezing the medicine into the hose 5. The medicine enters the indwelling needle through the hose 5 to achieve automatic injection. When the clamp-type flow sensor 9 detects that the injection volume has reached the set value, the reduction motor 84 stops working to achieve quantitative injection. After setting the injection volume, medical staff can stay away from the device to avoid the impact of radiation on the body.
