[0002] Currently, air pollution is quite serious, which has a significant impact on people's nasal health. The number of people suffering from rhinitis, which is mainly caused by respiratory tract infections through the nasal cavity and spreads rapidly, is gradually increasing. In order to treat nasal diseases and prevent the spread of nasal viral infections, nasal nebulizers are often used to administer medication to the nasal cavity.

[0003] Existing nasal nebulizers have a simple structure, making it inconvenient to administer medication in precise quantities. This results in unequal amounts of medication in the two nasal cavities, affecting the therapeutic effect and presenting certain limitations in their use. Utility Model Content

[0004] The purpose of this invention is to provide a nasal nebulizer for administering traditional Chinese medicine to children, in order 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 nasal nebulizer for pediatric traditional Chinese medicine includes an injection tube, a needle tube, and a nebulizer head. The needle tube and the nebulizer head are detachably connected to the bottom of the injection tube. A piston is slidably connected to the inner cavity of the injection tube. A piston rod is provided in the middle of the upper surface of the piston. A pressing block is provided at the top of the piston rod. A wing plate is provided at the top of the injection tube. An extension plate is provided on the side wall of the pressing block. A sliding rod is provided at the bottom end of the extension plate.

[0027] like Figure 1-3 As shown, this utility model discloses a nasal nebulizer for pediatric traditional Chinese medicine, comprising an injection tube 1, a needle tube 10, and a nebulizer head 12. Both the needle tube 10 and the nebulizer head 12 are detachably connected to the bottom of the injection tube 1. A connector 14 is provided at the middle of the bottom of the injection tube 1, and both the needle tube 10 and the nebulizer head 12 are threadedly connected to the connector 14. This threaded connection facilitates the disassembly and installation of the needle tube 10 and the nebulizer head 12. A needle tip 11 is provided at the bottom of the needle tube 10, with a diameter smaller than that of the needle tube 10. This smaller diameter ensures that when the needle tip 11 is inserted into the medicine bottle to draw liquid, the end of the needle tube 10 acts as a barrier, preventing the needle tube 10 from being inserted into the medicine bottle and affecting the efficiency of medicine dispensing. The atomizing head 12 has a cone-shaped structure with a large top and a small bottom. The cone-shaped atomizing head 12 can effectively prevent the atomizing head 12 from being completely inserted into the nasal cavity and causing nasal cavity damage.

[0028] The surface of the injection tube 1 is provided with an observation window 4, which has scale lines. The scale lines on the observation window 4 facilitate observation of the amount of liquid medicine drawn into the injection tube 1. A piston 15 is slidably connected to the inner cavity of the injection tube 1. A piston rod 5 is provided in the middle of the upper surface of the piston 15. A pressing block 6 is provided at the top of the piston rod 5. A wing plate 2 is provided at the top of the injection tube 1. Arc grooves 3 are provided on both sides of the bottom of the wing plate 2. The arc grooves 3 facilitate the restraint of the finger. An extension plate 7 is provided on the side wall of the pressing block 6. A sliding rod 8 is provided at the bottom of the end of the extension plate 7. A sliding hole 16 is provided on the end surface of the wing plate 2, which is slidably connected to the sliding rod 8. A limit member 9 that can move up and down is provided on the sliding rod 8. The limit member 9 is located above the wing plate 2. The limiting component 9 includes a sliding sleeve 17 that slides vertically and vertically connected to the sliding rod 8. A notch 18 is provided on one side of the sliding sleeve 17, and a first connecting block 19 and a second connecting block 20 are respectively provided on both sides of the notch 18. Through holes are provided on the surfaces of both the first connecting block 19 and the second connecting block 20, and bolts 21 pass through these holes. Bolts 21 are rotatably connected to the second connecting block 20. A nut 22 is provided on the surface of the first connecting block 19, and bolts 21 and nut 22 are threadedly connected. After the liquid medicine is drawn into the injection tube 1, the length of the sliding rod 8 between the extension plate 7 and the wing plate 2 is the length of the liquid medicine inside the injection tube 1. The medication volume is adjusted by first moving the limiting member 9 to the slide rod 8 located between the extension plate 7 and the wing plate 2. At this point, half of the medication is injected into one nasal cavity. The other half is then injected into the other nasal cavity, ensuring that the medication volume in both nasal cavities is equal. The specific operation for moving the limiting member 9 is as follows: first, loosen the bolt 21. This reduces the friction between the sliding sleeve 17 and the slide rod 8 due to the notch 18, allowing the sliding sleeve 17 to move. After positioning, tighten the bolt 21 to secure the slide rod 8. The operation is simple and quick. The slide rod 8 has graduated lines on its surface, facilitating precise adjustment of the limiting member 9's position.

[0029] The working principle of this pediatric Chinese medicine nasal nebulizer is as follows: When in use, first install the needle 10 on the injection tube 1, draw the medicine liquid from the medicine bottle into the injection tube 1, then remove the needle 10, install the nebulizer head 12 on the injection tube 1, adjust the position of the limiting member 9 on the slide rod 8 according to the amount of medicine liquid in the injection tube 1, then insert the nebulizer head 12 into one of the patient's nostrils to administer the medicine, and finally administer the other half of the medicine liquid into the other nostril, ensuring that the amount of medicine liquid in the two nostrils is equal.

[0030] It is understood that this utility model has been described through some embodiments, and those skilled in the art will recognize that various changes or equivalent substitutions can be made to these features and embodiments without departing from the spirit and scope of this utility model. Furthermore, under the teachings of this utility model, these features and embodiments can be modified to adapt to specific situations and materials without departing from the spirit and scope of this utility model. Therefore, this utility model is not limited to the specific embodiments disclosed herein, and all embodiments falling within the scope of the claims of this application are within the protection scope of this utility model.
