Description

Technical Field

[0001] This utility model relates to a medical device, and more particularly to a nasopharyngeal irrigator nozzle. Background Technology

[0002] Nasal irrigation solutions, also known as nasal sprays, are an important treatment method for preventing and treating various nasal diseases. Compared with oral medications, they have advantages such as better efficacy and higher safety. Nasal irrigation, as the name suggests, involves delivering an irrigation solution into the nasal cavity to achieve the purpose of cleaning and treatment. In addition to simple drug treatment, choosing a reliable nasal irrigation solution will significantly enhance the effect.

[0003] The most direct effect of nasal irrigation is to remove secretions from the nasal cavity and sinuses, reducing the adhesion of pathogens to the nasal mucosa. For patients after endoscopic sinus surgery, it can also help remove blood clots and prevent adhesions in the opened sinuses, nasal septum, and turbinates. In addition, it can improve ciliary movement of the nasal mucosa, maintaining its normal physiological function. Furthermore, it can control inflammatory mediators, reducing nasal mucosal swelling caused by inflammatory factors such as viral infections, the common cold, and allergic rhinitis, improving nasal ventilation, and shortening the recovery time for these conditions.

[0004] Currently, when using nasal sprays, the bottle must be held upright with the nozzle directly facing the nostril and the nozzle tip pointing towards the inside of the nasal cavity to spray the medication. However, because the nozzle is fixed to the bottle, patients usually need to be standing to spray the medication into their nasal cavity, which is inconvenient for patients lying down. Therefore, it is necessary to improve the current nasal spray nozzle structure. Utility Model Content

[0005] This invention addresses the shortcomings of existing technologies by providing a nasopharyngeal irrigation spray nozzle that allows for easy adjustment of the spray angle, making it convenient for patients lying down to use.

[0007] A nasopharyngeal irrigation spray nozzle includes a main structure, a pressing assembly disposed on the main structure, and a sprayer connected to the outer periphery of the pressing assembly. The sprayer is rotatable relative to the pressing assembly to adjust its angle, so that by applying pressure to the pressing assembly, the pressing assembly absorbs nasopharyngeal irrigation solution in the bottle and sprays it out along the sprayer into the patient's nasal cavity.

[0008] In the above technical solution, the component includes a pressing head and an elastic pressure suction element connected to the lower part of the pressing head. The sprayer is connected to the outer periphery of the pressing head of the pressing component, and the sprayer communicates with the elastic pressure suction element at the lower part of the pressing head.

[0009] In the above technical solution, the outer periphery of the pressing head has a connecting end, and the sprayer includes a rotary joint. The rotary joint is installed and connected to the connecting end of the outer periphery of the pressing head, and the rotary joint can rotate circumferentially relative to the connecting end of the pressing head to adjust the angle of the sprayer.

[0010] In the above technical solution, the sprayer also includes a flexible connecting tube, which is integrally formed on the rotary joint, and the flexible connecting tube can be adjusted in all directions relative to the rotary joint.

[0011] In the above technical solution, the sprayer also includes a spray port formed at the end of the flexible connecting tube, so that the nasopharyngeal irrigator adsorbed in the suction tube in the pressing assembly enters the flexible connecting tube through the suction tube by the elastic pressure pump, and the nasopharyngeal irrigator in the flexible connecting tube is sprayed out to the patient's nasal cavity through the spray port by the elastic pressure pump.

[0012] In the above technical solution, the elastic pressure suction device includes an elastic pressure pump and a suction tube connected to the lower part of the elastic pressure pump. One end of the suction tube is connected to the lower part of the elastic pressure pump, and the other end of the suction tube is placed inside the nasopharyngeal rinsing agent of the filling bottle body.

[0013] In the above technical solution, the pressing head is connected to the elastic pressure pump, and one end of the elastic pressure pump is located at the connection end on the outer periphery of the pressing head so as to communicate with the sprayer.

[0014] In the above technical solution, the main structure is installed on the bottle structure. The main structure includes a rotating part with an internal thread on its inner peripheral wall. The bottle structure includes a filling bottle with a bottle mouth at its end and an external thread on its outer peripheral wall. The internal thread of the rotating part in the main structure meshes with the external thread of the bottle mouth, so that the rotating part of the main structure is screwed onto the bottle mouth of the filling bottle.

[0015] In the above technical solution, the upper part of the filling bottle has a receiving cavity for accommodating the flexible connecting tube of the sprayer and the spray port formed at the end of the flexible connecting tube.

[0016] In the above technical solution, the main structure further includes a connecting part formed on the rotating part, and the pressing head of the pressing assembly is mounted on the connecting part of the main structure, and the pressing head can retract and slide relative to the connecting part of the main structure.

Obviously, the described embodiments are only a part of the embodiments of this utility model, not all of them. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model. Therefore, the following detailed description of the embodiments of this utility model provided in the accompanying drawings is not intended to limit the scope of the claimed utility model, but merely to represent selected embodiments of this utility model.

[0024] Please refer to the following: Figures 1 to 3 As shown, the present invention discloses a nasopharyngeal irrigation spray nozzle, including a main structure 100, a pressing component 200 disposed on the main structure 100, and a sprayer 300 disposed on the pressing component 200. By applying pressure to the pressing component 200, the pressing component 200 absorbs nasopharyngeal irrigation solution in the bottle and sprays it out along the sprayer 300 into the patient's nasal cavity to achieve a therapeutic effect on the patient.

[0025] For further details, please refer to the following: Figure 1 as well as Figure 2As shown, the main structure 100 is mounted on the bottle structure 400. Specifically, the bottle structure 400 includes a filling bottle 401 and a protective cover 402 disposed on the filling bottle 401. A receiving cavity 403 is formed in the upper part of the filling bottle 401 to receive the sprayer 300. A slot 404 is formed on the outer periphery of the filling bottle 401, allowing the protective cover 402 to be engaged with the slot 404 on the outer periphery of the filling bottle 401, and the protective cover 402 can be removed along the slot 404 on the outer periphery of the filling bottle 401. The bottle body of the filling bottle 401 is used to fill nasopharyngeal irrigant.

[0026] In this embodiment, the end of the filling bottle 401 is formed with a bottle mouth, and the outer peripheral wall of the bottle mouth is provided with an external thread. The main structure 100 includes a rotating part 101 and a connecting part 102 formed on the rotating part 101. The inner peripheral wall of the rotating part 101 is provided with an internal thread, and the internal thread of the rotating part 101 engages with the external thread of the bottle mouth of the filling bottle 401, so that the rotating part 101 of the main structure 100 is screwed onto the bottle mouth of the filling bottle 401.

[0027] A pressing component 200 is provided on the connecting part 102 of the main structure 100. For details, please refer to the relevant documentation. Figure 3 As shown, the pressing assembly 200 includes a pressing head 201 and an elastic pressure suction member 202 connected to the lower part of the pressing head 201. The outer periphery of the pressing head 201 has a connecting end for mounting and connecting the sprayer 300. By applying pressure to the pressing head 201, the elastic pressure suction member absorbs the nasopharyngeal rinsing agent in the bottle 401 and then sprays it out along the sprayer 300.

[0028] In this embodiment, the pressing head 201 is installed on the connecting part 102 of the main structure 100, and the pressing head 201 can retract and slide relative to the connecting part 102 of the main structure 100. The elastic pressure suction component 202 includes an elastic pressure pump 2021 and a suction tube 2022 connected to the lower part of the elastic pressure pump 2021. The pressing head 201 is connected to the elastic pressure pump 2021. One end of the suction tube 2022 is connected to the lower part of the elastic pressure pump 2021, and the other end of the suction tube 2022 is placed inside the nasopharyngeal rinsing agent of the filling bottle 401.

[0029] The upper end of the elastic pressure pump 2021 is located at the connecting end of the outer periphery of the pressing head 201 to communicate with the sprayer 300. By applying a certain pressure to the pressing head 201, the elastic pressure pump is driven to contract, causing the suction tube of the elastic pressure suction element 202 to absorb the nasopharyngeal rinsing agent in the bottle 401. Then, by releasing the pressing head 201, the elastic pressure pump is released, and the elastic pressure pump drives the pressing head 201 to return to its original position relative to the connecting part 102 of the main structure 100, causing the nasopharyngeal rinsing agent absorbed in the suction tube to be sprayed out along the sprayer 300.

[0030] The spray nozzle 300 is connected to the outer periphery of the pressing head 201 of the pressing assembly 200, and the spray nozzle 300 can be rotated relative to the pressing head 201 of the pressing assembly 200 to adjust the angle. The spray nozzle 300 communicates with the elastic pressure suction member 202 at the lower part of the pressing head 201. Specifically, the spray nozzle 300 includes a rotary connector 301, a flexible connecting tube 302 connected to the rotary connector 301, and a spray port 303 formed at the end of the flexible connecting tube 302. This allows the nasopharyngeal irrigant adsorbed in the suction tube of the pressing assembly 200 to enter the flexible connecting tube 302 through the suction tube 2022 via the elastic pressure pump 2021, and then the nasopharyngeal irrigant in the flexible connecting tube 302 is sprayed out through the spray port 303 to the patient's nasal cavity by the elastic pressure pump 2021.

[0031] In this embodiment, the rotary connector 301 is installed and connected to the connecting end of the outer periphery of the pressing head 201, and the rotary connector 301 can rotate circumferentially relative to the connecting end of the pressing head 201 to adjust the angle of the sprayer 300. The flexible connecting tube 302 is integrally formed on the rotary connector 301, and the flexible connecting tube 302 can be adjusted in all directions relative to the rotary connector 301 so that the spray port 303 at the end of the flexible connecting tube 302 can be inserted into the patient's nasal cavity more quickly and conveniently, thereby better spraying the medicine into the nasal cavity of the patient who is lying down or standing. In addition, the flexible connecting tube 302 can prevent damage to the patient's nasal cavity.

[0032] In use, first open the protective cover 402 of the bottle structure 400. Depending on the patient's standing or lying position, rotate the rotary connector 301 of the sprayer 300 circumferentially relative to the connecting end of the pressing head 201 by a certain angle, so that the flexible connecting tube 302 and the spray port 303 are rotated out along the receiving cavity at the top of the filling bottle 401. Then, adjust the direction of the flexible connecting tube 302 and the spray port 303 relative to the rotary connector 301 so that the spray port 303 at the end of the flexible connecting tube 302 is facing the patient's nasal cavity. Then, insert the spray port 303 of the sprayer 300 into the patient's nasal cavity and apply a certain pressure to the pressing head 201 to drive the sprayer. The contraction of the pressure pump causes the suction tube 2022 of the elastic pressure suction component 202 to absorb the nasopharyngeal rinsing agent inside the bottle 401. Then, by releasing the press head 201, the elastic pressure pump 2021 is released, and the elastic pressure pump 2021 drives the press head 201 to return to the connection part 102 of the main structure 100, so that the nasopharyngeal rinsing agent absorbed in the suction tube 2022 is sprayed into the patient's nasal cavity along the sprayer 300, thereby completing the treatment of the patient's nasal disease. Finally, the flexible connecting tube 302 and the spray port 303 are placed into the receiving cavity at the top of the bottle 401, and the protective cover 402 is snapped into the groove on the outer periphery of the bottle 401.

[0033] In summary, the nasopharyngeal irrigation nozzle of this invention allows for angle adjustment by rotating the sprayer 300 relative to the pressing assembly 200, making it easier to insert the spray port 303 of the sprayer into the patient's nasal cavity, thereby better spraying the medication into the nasal cavity of a lying patient. Furthermore, the flexible connecting tube 302 of the sprayer 300 can prevent damage to the patient's nasal cavity, thus improving the safety and convenience of the treatment process.
