A liquid medicine transmission pipe 6 is slidably connected inside the transmission pipe installation groove 14. A medicine powder bottle placement tray 5 is slidably connected to the inner side of the protective plate 4. Second sliders 7 are fixedly connected to both sides of the medicine powder bottle placement tray 5. The surface of the second slider 7 is slidably connected to the inner side of the protective plate 4. A limiting block 8 is slidably connected inside the second slider 7. Two limiting grooves 13 are opened on both sides of the protective plate 4. The user tightens the bottom of the liquid medicine transmission pipe 6 on the medicine bag, installs the liquid medicine transmission pipe 6 inside the transmission pipe installation groove 14. After opening the aluminum cap of the medicine powder bottle, invert the medicine powder bottle on the medicine powder bottle placement tray 5. By pushing the medicine powder bottle downward, the medicine powder bottle placement tray 5 is driven to move downward, so that the needle at the top of the liquid medicine transmission pipe 6 is inserted into the medicine powder bottle. Push the limiting block 8 into the limiting groove 13 to limit the position of the medicine powder bottle placement tray 5. Squeeze the medicine bag to make the liquid medicine enter the medicine powder bottle to dissolve the medicine powder. Place the medicine bottle on the medicine powder bottle placement tray 5, so that the dissolved liquid medicine in the medicine powder bottle on the medicine powder bottle placement tray 5 flows back into the medicine bag. The protective plate 4 protects the position of the needle hole of the liquid medicine transmission pipe 6, which can prevent the needle hole of the liquid medicine transmission pipe 6 from stabbing the user.

[0023] Refer to Figure 3 As shown in the figure, in this implementation: One side of the limiting block 8 is fixedly connected to a tension spring 9. The other end of the tension spring 9 is fixedly connected to one side inside the second slider 7. After the user places the medicine powder bottle on the medicine powder bottle placement tray 5, pull the limiting block 8 to release the limit on the medicine powder bottle placement tray 5, so that the medicine powder bottle placement tray 5 can move downward. By pressing the medicine powder bottle downward, the medicine powder bottle placement tray 5 is driven to move downward. When the limiting block 8 moves to the lower limiting groove 13, under the pulling force of the tension spring 9, pull the limiting block 8 into the lower limiting groove 13 to limit the medicine powder bottle placement tray 5.

[0024] Refer to Figure 3 As shown in the figure, in this implementation: Limiting chutes 10 are opened at the top and bottom inside the second slider 7. Limiting sliders 11 are fixedly connected to the top and bottom of the limiting block 8. After the user places the medicine powder bottle on the medicine powder bottle placement tray 5, pull the limiting block 8 to release the limit on the medicine powder bottle placement tray 5. During the process of pulling the limiting block 8, the limiting sliders 11 at the top and bottom of the limiting block 8 move inside the limiting chutes 10 to limit the movement of the limiting block 8.

[0025] Refer to Figure 4As shown, in this implementation: The bottoms of the limiting blocks 8 and the bottom inside the limiting grooves 13 are both inclined surfaces. After the user places the powder medicine bottle on the powder medicine bottle placement tray 5, by pushing the powder medicine bottle downward, a downward moving force is applied to the powder medicine bottle placement tray 5. During the downward movement of the powder medicine bottle placement tray 5, the inclined surface at the bottom of the limiting block 8 is squeezed and moves outward, disengaging from the inside of the limiting groove 13. When the limiting block 8 moves to the position of the lower limiting groove 13, the extrusion on the limiting block 8 is released, and under the pulling force of the tension spring 9, the tension spring 9 is pulled into the inside of the lower limiting groove 13 to limit the powder medicine bottle placement tray 5.

[0026] Refer to Figure 5 and Figure 6 As shown, in this implementation: A limiting inclined plate 15 is slidably connected inside the transmission pipe installation groove 14. One side of the limiting inclined plate 15 is fixedly connected to a pull rod 16. After the user installs the liquid medicine transmission pipe 6 into the transmission pipe installation groove 14, the pull rod 16 is pushed to move the limiting inclined plate 15 inward to limit the liquid medicine transmission pipe 6, preventing accidental contact with the liquid medicine transmission pipe 6 during operation and causing the liquid medicine transmission pipe 6 to move outward, resulting in the misalignment of the hole position of the powder medicine bottle placement tray 5 and the needle of the liquid medicine transmission pipe 6.

[0027] Refer to Figure 6 As shown, in this implementation: First chutes 17 are provided at both the top and bottom inside the transmission pipe installation groove 14. First sliders 18 are fixedly connected to both the top and bottom of the limiting inclined plate 15. When the user pushes and pulls the pull rod 16 to drive the limiting inclined plate 15 to move, the first sliders 18 at the top and bottom of the limiting inclined plate 15 slide inside the first chutes 17 to assist the movement of the limiting inclined plate 15 and prevent the limiting inclined plate 15 from tilting during the movement, resulting in stuck movement.

[0028] Refer to Figure 6 As shown, in this implementation: A thrust spring 19 is fixedly connected to one side of the limiting inclined plate 15, and the other end of the thrust spring 19 is fixedly connected to one side inside the transmission pipe installation groove 14. When the user needs to install the liquid medicine transmission pipe 6 into the transmission pipe installation groove 14, the liquid medicine transmission pipe 6 is aligned with the position of the transmission pipe installation groove 14 and inserted, and the liquid medicine transmission pipe 6 is moved into the transmission pipe installation groove 14. During the movement of the liquid medicine transmission pipe 6, the rear side of the transmission pipe installation groove 14 squeezes the inclined surface of the limiting inclined plate 15, causing the limiting inclined plate 15 to move outward. When the transmission pipe installation groove 14 moves to the rear of the limiting inclined plate 15, the extrusion on the limiting inclined plate 15 is released, and under the thrust of the thrust spring 19, the limiting inclined plate 15 is pushed inward to limit the liquid medicine transmission pipe 6.

[0029] Working principle: The user tightens the bottom of the liquid medicine transmission tube 6 on the medicine bag, installs the liquid medicine transmission tube 6 inside the transmission tube installation groove 14. After opening the aluminum cap of the medicine powder bottle, invert the medicine powder bottle on the medicine powder bottle placement tray 5. By pushing the medicine powder bottle downward, drive the medicine powder bottle placement tray 5 to move downward, so that the needle at the top of the liquid medicine transmission tube 6 inserts into the medicine powder bottle. Push the limit block 8 into the limit groove 13 to limit the position of the medicine powder bottle placement tray 5. Squeeze the medicine bag to make the liquid medicine enter the medicine powder bottle to dissolve the medicine powder. Place the medicine bottle on the medicine powder bottle placement tray 5 so that the dissolved liquid medicine in the medicine powder bottle on the medicine powder bottle placement tray 5 flows back into the medicine bag. After the user places the medicine powder bottle on the medicine powder bottle placement tray 5, pull the limit block 8 to release the limit on the medicine powder bottle placement tray 5, so that the medicine powder bottle placement tray 5 can move downward. By pressing the medicine powder bottle downward, drive the medicine powder bottle placement tray 5 to move downward. When the limit block 8 moves to the lower limit groove 13, under the pulling force of the tension spring 9, pull the limit block 8 into the lower limit groove 13 to limit the medicine powder bottle placement tray 5. After placing the medicine powder bottle on the medicine powder bottle placement tray 5, pull the limit block 8 to release the limit on the medicine powder bottle placement tray 5. During the process of pulling the limit block 8, the limit sliders 11 at the top and bottom of the limit block 8 move inside the limit sliding groove 10 to limit the movement of the limit block 8. After placing the medicine powder bottle on the medicine powder bottle placement tray 5, by pushing the medicine powder bottle downward, apply a downward moving force to the medicine powder bottle placement tray 5. During the downward movement of the medicine powder bottle placement tray 5, the inclined surface at the bottom of the limit block 8 is squeezed and moves outward, disengaging from the inside of the limit groove 13. When the limit block 8 moves to the position of the lower limit groove 13, release the extrusion on the limit block 8. Under the pulling force of the tension spring 9, pull the tension spring 9 into the lower limit groove 13 to limit the medicine powder bottle placement tray 5. After installing the liquid medicine transmission tube 6 inside the transmission tube installation groove 14, push the pull rod 16 to make the limit inclined plate 15 move inward to limit the liquid medicine transmission tube 6 and prevent accidental contact with the liquid medicine transmission tube 6 during operation, causing the liquid medicine transmission tube 6 to move outward. When pushing and pulling the pull rod 16 to drive the limit inclined plate 15 to move, the first sliders 18 at the top and bottom of the limit inclined plate 15 slide inside the first sliding groove 17 to assist the movement of the limit inclined plate 15 and prevent the limit inclined plate 15 from tilting during the movement process. When the liquid medicine transmission tube 6 needs to be installed inside the transmission tube installation groove 14, align the liquid medicine transmission tube 6 with the position of the transmission tube installation groove 14 and insert it. Move the liquid medicine transmission tube 6 into the transmission tube installation groove 14. During the movement of the liquid medicine transmission tube 6, the rear side of the transmission tube installation groove 14 squeezes the inclined surface of the limit inclined plate 15, causing the limit inclined plate 15 to move outward. When the transmission tube installation groove 14 moves to the rear of the limit inclined plate 15, release the extrusion on the limit inclined plate 15. Under the pushing force of the thrust spring 19, push the limit inclined plate 15 to move inward.
