[0025] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this utility model.

[0026] Example 1

[0027] like Figures 1-3 As shown, this embodiment proposes a clinical drug delivery device for respiratory physicians, including a spray pump 1. A control panel 2 is fixedly connected to one side of the spray pump 1, and a hose 3 is provided on the other side of the spray pump 1. An atomizer 4 is provided at one end of the hose 3. A connecting pipe 5 is fixedly connected to one side of the atomizer 4. A nozzle 6 is provided at one end of the connecting pipe 5. A cylinder 7 is fixedly connected to the top of the atomizer 4. A piston rod 12 is slidably connected inside the cylinder 7. A connecting block 8 is fixedly connected to one end of the piston rod 12. A rack 9 is fixedly connected to one side of the connecting block 8. A ball valve 13 is provided inside the connecting pipe 5. A rotating rod 11 is fixedly connected to the outside of the ball valve 13. A gear 10 is fixedly connected to the top of the rotating rod 11. The gear 10 meshes with the rack 9.

[0028] In this embodiment, the control panel 2 and the cylinder 7 are electrically connected, and the connecting pipe 5 is in contact with the nozzle 6, which makes it easy to start the cylinder 7 by operating the control panel 2.

[0029] In this embodiment, the connecting block 8 is in contact with the top of the atomizer 4, and the rack 9 is slidably connected to the top of the atomizer 4, which allows the connecting block 8 to move while driving the rack 9 to move.

[0030] In this embodiment, the rotating rod 11 extends to the outside of the connecting pipe 5, and the rotating rod 11 and the connecting pipe 5 are connected by a bearing, which makes it easy for the rotating rod 11 to rotate while driving the ball valve 13 to rotate.

[0031] In use, medical staff first fill the nebulizer 4 with the medication and connect both ends of the hose 3 to the spray pump 1 and the nebulizer 4 respectively. Then, the spray pump 1 is powered on and started through the control panel 2. At this time, the medication inside the nebulizer 4 will be sprayed out from the nozzle 6 through the connecting tube 5. The patient needs to put the nozzle 6 into their mouth beforehand. When it is necessary to adjust the amount of medication sprayed, the medical staff can start the cylinder 7 through the control panel 2. At the same time, the cylinder 7 starts, which drives the connecting block 8 to move through the piston rod 12. The movement of the connecting block 8 drives the rack 9 to move, which drives the gear 10 to rotate. The rotation of the gear 10 drives the rotating rod 11 to rotate, which drives the ball valve 13 to rotate. At this time, the larger the angle of rotation of the ball valve 13, the smaller the amount of medication discharged. At this time, the medical staff can accurately adjust the amount of medication dispensed by the drug delivery device according to the patient's condition, age, weight, and drug sensitivity, ensuring that each patient receives the most suitable medication dosage.

[0032] Example 2

[0033] like Figures 4-5 As shown, based on the same concept as Embodiment 1 above, this embodiment also proposes that one end of the nozzle 6 is fixedly connected to two fixing rods 14, and the interior of each fixing rod 14 is provided with a limiting groove 15, and one end of the connecting pipe 5 is provided with two connecting grooves 16.

[0034] In this embodiment, connecting grooves 17 are provided on both outer sides of the connecting pipe 5. Connecting groove 16 and connecting groove 17 are interconnected, and fixing rod 14 is in contact with connecting groove 16, which facilitates the movement of fixing rod 14 inside connecting groove 16.

[0035] In this embodiment, each of the two connecting grooves 17 is provided with a limiting rod 20. One end of each limiting rod 20 is fixedly connected to a pull plate 19. The limiting rod 20 is in contact with the inside of the limiting groove 15, which makes it easy for the limiting rod 20 to limit and fix the fixing rod 14 through the limiting groove 15.

[0036] In this embodiment, two springs 18 are fixedly connected to one side of each of the two pull plates 19. The four springs 18 are fixedly connected to the outer sides of the connecting pipe 5, which facilitates the movement of the pull plates 19 while driving the two springs 18 to extend and retract.

[0037] After the patient completes the medication treatment, bacteria, viruses, and other harmful substances may remain in the nozzle 6. At this time, the staff will first pull the two pull plates 19 in opposite directions. As the two pull plates 19 move, they will also cause the four springs 18 to extend. As the two pull plates 19 move, they will also cause the two limit rods 20 to move. When the two limit rods 20 move to the point where the contact between them and the inside of the two limit grooves 15 disappears, the limiting relationship between the two fixed rods 14 and the two limit rods 20 will also disappear. At this time, the staff can quickly disassemble the nozzle 6 for disinfection and cleaning to prevent cross-infection caused by multiple people using it.

[0038] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
