Description
Technical Field
[0001] This utility model relates to the field of nasal irrigator technology, specifically a convenient nasal irrigator for injection. Background Technology
[0002] A nasal irrigator is a tool used to clean the nasal cavity. Its principle is mainly based on the physical flushing effect of water flow and the biological properties of saline solution to clean and maintain the nasal cavity.
[0003] When rinsing your nose, tilt your head to one side so that your nasal cavity is facing the nasal irrigator so that the nasal rinse solution can flow out smoothly. Gently insert the nozzle of the nasal irrigator into one nostril and gently squeeze to let the saline solution flow out of the nasal cavity.
[0004] However, existing nasal irrigators generally consist of a canister and a nozzle. During use, it is difficult to control the injection volume when squeezing the canister to inject saline into the nasal cavity. If the injection volume is too large at one time, the saline may enter the trachea, which is dangerous. Therefore, this application proposes a nasal irrigator that is easy to inject.

[0026] To better understand the above technical solutions, the following will provide a detailed explanation of the technical solutions in conjunction with the accompanying drawings and specific implementation methods.
[0027] This utility model discloses a convenient nasal irrigator for injection, according to the attached... Figure 1-4 As shown, it includes a syringe 1, and a nasal irrigator tip 2 is installed at the end of the syringe 1.
[0028] The syringe 1 includes a barrel 11 and an injection port 12, with the injection port 12 fixedly disposed at the end of the barrel 11;
[0029] The top of the nasal irrigator end 2 is fitted onto the outside of the injection port 12. An external threaded sleeve 3 is also fixedly fitted onto the outside of the injection port 12. An internal threaded sleeve 4 is rotatably provided on the top of the nasal irrigator end 2, and the internal threaded sleeve 4 is threadedly connected to the external threaded sleeve 3.
[0030] A pull rod 13 is movably inserted into the inside of the cylinder 11, and a rubber plug 14 is fixedly connected to the end of the pull rod 13. The rubber plug 14 is slidably disposed inside the cylinder 11.
[0031] During use, the movement of the rubber stopper 14 within the cylinder 11 allows saline solution to be drawn into the cylinder 11 through the injection port 12 and the nasal irrigator tip 2. When injecting saline solution, the nasal irrigator tip 2 is directly inserted into the nasal cavity. At this time, pushing the rubber stopper 14 within the cylinder 11 allows the saline solution to be injected into the nasal cavity. The movement of the rubber stopper 14 within the cylinder 11 can be easily controlled by the lever 13, thus facilitating the control of the saline solution injection rate and volume.
[0032] The internal threaded sleeve 4 and the external threaded sleeve 3 are used to install and remove the syringe 1 and the nasal irrigator end 2, which facilitates the cleaning of the nasal irrigator end 2. On the other hand, they can increase the sealing between the syringe 1 and the nasal irrigator end 2 to prevent air leakage during injection and aspiration.
[0033] Furthermore, the other end of the lever 13 extends outward and is fixedly connected to a button 15. The button 15 allows the lever 13 to be pulled and pressed, causing the rubber stopper 14 to move within the cylinder 11.
[0034] Furthermore, the cross section of the tie rod 13 is set to a cross shape, and multiple slots are opened on the outside of the tie rod 13, so that the cross section of the tie rod 13 is set to a cross shape, thereby reducing the space occupied by the tie rod 13 while maintaining the structural strength of the tie rod 13.
[0035] Specifically disclosed, the nasal irrigator tip 2 includes a rubber head 21, a slot 22, and a media channel 23. The slot 22 and the media channel 23 are formed inside the rubber head 21, and the injection port 12 is inserted into the inner wall of the slot 22.
[0036] The rubber head 21 is teardrop-shaped with a structure that is narrow at the front and wide at the back;
[0037] Furthermore, a flushing port is provided at the bottom of the rubber head 21, and the injection port 12, the medium channel 23 and the flushing port are connected.
[0038] Furthermore, a sealing ring 5 is rotatably connected to the top of the rubber head 21, and an internal threaded sleeve 4 is fixedly connected above the sealing ring 5, with the sealing ring 5 abutting against the external threaded sleeve 3.
[0039] Furthermore, a rotating groove is provided on the top of the rubber head 21, and a rotating ring is fixedly connected below the sealing ring 5, and the rotating ring is slidably disposed on the inner wall of the rotating groove.
[0040] By utilizing the sealing ring 5, when installing the internal threaded sleeve 4 and the external threaded sleeve 3, the sealing ring 5 abuts against the external threaded sleeve 3, thereby further increasing the sealing performance and preventing leakage.
[0041] During use, the movement of the rubber stopper 14 within the cylinder 11 allows saline solution to be drawn into the cylinder 11 through the injection port 12 and the nasal irrigator tip 2. When injecting saline solution, the nasal irrigator tip 2 is directly inserted into the nasal cavity. At this time, pushing the rubber stopper 14 within the cylinder 11 allows the saline solution to be injected into the nasal cavity. The movement of the rubber stopper 14 within the cylinder 11 can be easily controlled by the lever 13, thus facilitating the control of the saline solution injection rate and volume.
[0042] The internal threaded sleeve 4 and the external threaded sleeve 3 are used to install and remove the syringe 1 and the nasal irrigator end 2, which facilitates the cleaning of the nasal irrigator end 2. On the other hand, they can increase the sealing between the syringe 1 and the nasal irrigator end 2 to prevent air leakage during injection and aspiration.
