Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0017] Example 1 Please see Figures 1 to 5 This invention provides a technical solution: an intelligent dual-drug adjustable dosage mixing injection device, including a syringe 1. The syringe 1 has an internal mounting cavity 2. Two partitions 8 are fixedly connected inside the mounting cavity 2. A second injection pen 10 is placed inside the mounting cavity 2 on one side of one partition 8, and a first injection pen 9 is placed inside the mounting cavity 2 on one side of the other partition 8. Adjustment windows 11 are installed on the surfaces of both the first injection pen 9 and the second injection pen 10. Two mounting sleeves 13 are placed at one end of the syringe 1. A mounting base 17 is fixedly connected to one end of each mounting sleeve 13. A knob 15 is installed on the surface of both the first injection pen 9 and the second injection pen 10. A button 16 is installed at one end of both the first injection pen 9 and the second injection pen 10. The first injection pen 9 and the second injection pen 10 respectively store semaglutide and insulin.

[0018] One side of the inner cavity of the mounting base 17 is fixedly connected to a fixing ring 18. The fixing ring 18 has a through hole 20 inside. The fixing ring 18 has an annular cavity 21 inside and outside the through hole 20. Two sliders 19 are slidably connected inside the annular cavity 21. The outer side of one end of the knob 15 is located inside the through hole 20. When the first transmission gear 22 is driven to rotate by the second transmission gear 33, the first transmission gear 22 drives the slider 19 to slide inside the annular cavity 21.

[0019] Among them, the outer side of the knob 15 is movably fitted with a first transmission gear 22, one end of the first transmission gear 22 is fixedly connected to one end of the two sliders 19, and a self-locking motor 32 is fixedly connected to one side of the inner cavity of the mounting base 17. The output end of the self-locking motor 32 is fixedly fitted with a second transmission gear 33 that meshes with the first transmission gear 22, and the first transmission gear 22 can be driven to rotate through the second transmission gear 33.

[0020] Each of the first transmission gears 22 has a clamping ring 23 on one side, which is sleeved on the outside of the knob 15. The other end of each of the first transmission gears 22 is fixedly connected to two connecting posts 24, one end of which is fixedly connected to one end of the clamping ring 23. The first transmission gear 22 can rotate and drive the clamping ring 23 through the two connecting posts 24, which in turn drive the clamping block 27 and the knob 15 to rotate through the threaded rod 25.

[0021] The clamping ring 23 has threaded grooves 26 at both the top and bottom. Threaded rods 25 are threadedly connected inside the threaded grooves 26. One end of each threaded rod 25 extends to the inside of the clamping ring 23 and is connected to a clamping block 27 via a bearing. The other end of each threaded rod 25 extends to the outside of the clamping ring 23. The threaded rod 25 can drive the bearing to move the clamping block 27.

[0022] Each clamping block 27 has a guide rod 28 fixedly connected to its surface. One end of each guide rod 28 passes through the inside of the clamping ring 23 and extends to the outside of the clamping ring 23. The outside of each guide rod 28 is slidably connected to the inside of the clamping ring 23. The threaded rod 25 pushes the clamping block 27 to move through the bearing, so that the clamping block 27 drives the guide rod 28 to slide along the inside of the clamping ring 23.

[0023] Each of the mounting sleeves 13 has a camera 14 fixedly connected to its inner wall. The position of the camera 14 is matched with the adjustment window 11. The camera 14 captures the display scale image of the adjustment window 11 so as to adjust to the appropriate drug injection volume.

[0024] One end of the mounting base 17 is fixedly connected to a first servo motor 29. The output end of the first servo motor 29 is fixedly connected to a second electric telescopic rod 30. The telescopic end of the second electric telescopic rod 30 is fixedly connected to a push block 31. The position of the push block 31 is matched with the position of the button 16. The position of the second electric telescopic rod 30 and the push block 31 can be adjusted through the output end of the first servo motor 29 so as to trigger the button 16 and install the second injection pen 10 and the first injection pen 9 into the mounting cavity 2.

[0025] Example 2 Please see Figure 1 , Figure 4 and Figure 5The present invention provides a technical solution: two first electric telescopic rods 12 are fixedly connected to one end of a syringe 1. The telescopic ends of the two first electric telescopic rods 12 are respectively fixedly connected to one end of two mounting sleeves 13. A storage cavity 34 is opened inside the syringe 1 on one side of the first injection pen 9 and the second injection pen 10. A second servo motor 35 is fixedly connected to one end of the inner cavity of the storage cavity 34. A threaded shaft 36 is rotatably connected to the other end of the inner cavity of the storage cavity 34. The output end of the second servo motor 35 is fixedly connected to one end of the threaded shaft 36. A moving block 37 is threadedly connected to the outer side of the threaded shaft 36. One end of the moving block 37 extends into the inner cavity 2 and is fixedly connected to a limiting clamp 38. The surfaces of the two limiting clamps 38 are respectively connected to the first servo motor 9 and the second servo motor 10. The surfaces of the second injection pen 10 and the first injection pen 9 are in contact. A controller 39 is fixedly connected to the surface of the syringe 1. Two insertion heads 3 are fixedly connected to one end of the inner wall of the mounting cavity 2. A connecting end 40 is installed at one end of both the first injection pen 9 and the second injection pen 10. One end of the connecting end 40 is inserted into the insertion head 3. A tube 4 is fixedly connected to the inside of the syringe 1 and at one end of the insertion head 3. A threaded connector 6 is fixedly connected to one end of the syringe 1. A threaded head 5 is threaded inside the threaded connector 6. One end of the threaded head 5 extends to the outside of the threaded connector 6 and is fixedly connected to a needle 7. The threaded connector 6 is connected to the inside of the two tubes 4. The tubes 4 are connected to the inside of the connecting end 40 through the insertion head 3 so that the controller 39 can control the operation of the device.

[0026] In summary, when using this intelligent dual-drug adjustable dosage mixing injection device, the second injection pen 10 and the first injection pen 9 are placed into the two chambers inside the mounting cavity 2, so that one end of the connecting end 40 is inserted into the insert head 3. Then, the output end of the second servo motor 35 drives the threaded shaft 36 to rotate, so that the threaded shaft 36 drives the moving block 37 to move the limiting clamp 38, so that the two limiting clamps 38 contact the surfaces of the first injection pen 9 and the second injection pen 10 respectively, limiting the first injection pen 9 and the second injection pen 10 inside the mounting cavity 2. Then, the operator rotates the threaded rod 25, so that the threaded rod 25 pushes the clamp 27 to move, so that the clamp 27 contacts the surface of the knob 15, connecting the clamp ring 23 and the knob 15. Then, the output end of the first servo motor 29 drives the second electric telescopic rod 30 and the push block 31 to rotate, so that the second electric telescopic rod 30 and the push block 31 rotate to one end of the button 16. At this time, the self-locking motor 32... The output end drives the second transmission gear 33 to rotate, which in turn drives the first transmission gear 22 to rotate. The first transmission gear 22 then drives the clamping ring 23 to rotate via the connecting column 24. The clamping ring 23 then drives the knob 15 to rotate via the threaded rod 25 and the clamping block 27. The knob 15 rotates to adjust the injection volume of the second injection pen 10 and the first injection pen 9. The camera 14 identifies the scale displayed on the adjustment window 11. When the appropriate volume is reached, the self-locking motor 32 stops working. Then, the needle 7 is inserted into the patient's body. The telescopic end of the second electric telescopic rod 30 pushes the push block 31 to move, which in turn pushes the button 16 to move. The liquid medicine inside the second injection pen 10 and the first injection pen 9 is injected into the insertion head 3 through the connecting end 40, then enters the threaded head 5 through the pipe 4, and is then injected into the patient's body through the needle 7. After the injection is completed, the needle 7 is pulled out of the patient's body. Unscrew the threaded head 5 at one end of the needle 7 from the inside of the threaded connector 6. Move the extension end of the second electric telescopic rod 30 to reset the push block 31. The output end of the first servo motor 29 drives the second electric telescopic rod 30 and the push block 31 to rotate to one side of the mounting base 17. Then, the operator resets and rotates the threaded rod 25, causing the threaded rod 25 to drive the clamping block 27 and the guide rod 28 to reset and move. Release the clamping block 27 from fixing the knob 15 and release the connection between the clamping ring 23 and the knob 15. At the same time, the output end of the second servo motor 35 drives the threaded shaft 36 to reset and rotate, causing the threaded shaft 36 to drive the moving block 37 and the limiting clamp 38 to reset and move. Release the limiting fixation of the second injection pen 10 and the first injection pen 9. Then, remove the first injection pen 9 and the second injection pen 10 from the inside of the device through the through hole 20, the first transmission gear 22, and the clamping ring 23.
