Description

Technical Field

[0001] This invention belongs to the field of nasal irrigator technology, specifically relating to a negative pressure nasal irrigator with anti-backflow function. Background Technology

[0002] A nasal irrigator is a device specifically designed to clean the nasal cavity. In daily life, the nasal cavity can become unclean due to pollutants such as dust, pollen, and bacteria in the air, as well as the nasal mucus itself, leading to discomfort such as nasal congestion, runny nose, and sneezing. It may even trigger diseases like rhinitis and sinusitis. A nasal irrigator delivers a saline solution into the nasal cavity, using the water flow to rinse away dirt, allergens, and excess secretions, keeping the nasal cavity moist and clean. This helps relieve nasal discomfort, improves nasal ventilation, and maintains nasal health, making it a practical tool for both supplementary treatment and daily nasal care.

[0003] Traditional negative pressure nasal irrigators are mostly electric, expensive, and bulky, making them inconvenient to carry and store. They achieve negative pressure suction by using a motor with a fixed power output, which can easily cause users significant discomfort and psychological fear. Professional negative pressure nasal irrigation even requires users to frequently visit hospitals for professional services, a process that is cumbersome and expensive, preventing users from trying it out immediately. Summary of the Invention

[0004] The purpose of this invention is to provide a negative pressure nasal irrigator with anti-backflow function, so as to solve the problems of inconvenience in use, complicated operation, and difficulty in adjusting suction of traditional negative pressure nasal irrigators mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a negative pressure nasal irrigation device with anti-backflow function, the nasal irrigation device comprising a cleaning section, a negative pressure section, and an anti-backflow component;

[0006] The cleaning section is connected to the negative pressure section, and the anti-backflow component is disposed inside the negative pressure section;

[0007] An integral liquid outlet pipe is provided on the cleaning section, and a plug is provided on the side of the liquid outlet pipe. A connecting component is connected between the plug and the liquid outlet pipe.

[0008] The connecting assembly consists of plate one, plate two, connecting screw and spring;

[0009] The first plate and the second plate are arranged opposite to each other, and the adjacent sides of the two are provided with circular holes of different diameters. The diameter of the circular holes gradually decreases from the outside to the middle of the connecting component, so as to connect the liquid outlet tubes of different specifications of nasal irrigators. At the same time, the diameter of the innermost circular hole should be smaller than the diameter of the liquid outlet tubes on all nasal irrigators on the market, so as to avoid the phenomenon that irregular liquid outlet tubes are smaller than the diameter of the circular holes and cannot be clamped.

[0010] The connecting screw is fixed to the inner center of plate one and movably passes through plate two. A nut is also provided on the outside of plate two, which is screwed onto the connecting screw. The distance between plate one and plate two is adjusted by adjusting the nut, which can increase the diameter of the circular hole to clamp liquid outlet pipes of various diameters, and can also clamp irregularly shaped liquid outlet pipes. The spring is sleeved on the connecting screw, and its two ends abut against plate one and plate two respectively, thereby ensuring quick adjustment of plate one and plate two. It is worth noting that the function of the connecting assembly is to connect the plug and the liquid outlet pipe. In actual use, other structures that can achieve this function can also be used for connection.

[0011] Preferably, the plug and the liquid outlet tube on the nasal irrigator are both locked in the circular holes on the first plate and the second plate, and the plug has a liquid outlet on its outer side.

[0012] Preferably, the negative pressure section includes a collection container and a suction device; wherein the shape of the collection container is not limited.

[0013] A short flexible tube connects the inlet of the collection container to the plug on one side, and the horizontal plane of the inlet of the collection container is lower than the outlet of the plug.

[0014] The top of the collection container is fixed with a connector, and an inner hole I, which is wider at the top and narrower at the bottom, is formed in the connector. The inner hole I is funnel-shaped, and the anti-backflow component is disposed in the inner hole I.

[0015] The aspirator is connected to the connector. During use, one hand presses the nasal irrigator to expel the liquid inside through the outlet tube into the nasal cavity, while the other hand pulls the aspirator to create negative pressure inside the plug and collection container, moving the glass bulb towards the upper wide position of the inner hole. At this time, the plug, collection container, and aspirator form a negative pressure passage, thereby aspirating the nasal mucus and the cleansing liquid together. The mixture of nasal mucus and liquid flows into the collection container through the short tube. After use, the aspirator is released, and the gas flows back, pushing the glass bulb to seal the channel inside the inner hole, thereby preventing the backflow of gas and liquid.

[0016] Preferably, the end of the suction device is connected to a long flexible tube, and the end of the long flexible tube is connected to a connector that is inserted into the connector with an interference fit, thereby ensuring installation stability. In use, gas is transmitted through the long flexible tube.

[0017] Preferably, the end of the suction device is inserted into the connector, and the axes of the two coincide to achieve a direct connection. In use, after holding the suction device, the collection container can be twisted up directly, which is convenient to operate. In order to prevent the glass ball from moving out of the inner hole, a thin rod is provided at the top opening of the inner hole to limit the glass ball.

[0018] Preferably, the negative pressure device includes a balloon, one end of which is connected to a plug by a short flexible tube. The balloon is hollow, and when the balloon is pressed, the air inside the balloon is discharged from the other end. Then the balloon is released, at which point the balloon rebounds and generates negative pressure, thereby sucking out the mixture of mucus and cleaning liquid inside the plug.

[0019] Preferably, an inner hole II is formed inside one end of the balloon, and the inner diameter of the inner hole II gradually increases in the direction of the balloon. The anti-backflow component is a glass ball, which is placed inside the inner hole II. Similarly, in order to prevent the glass ball from entering the balloon, a thin rod is also required to limit it at the opening of the inner hole II facing the balloon. When the balloon is pressed, the gas will push the glass ball to block the inner hole II and prevent gas backflow. When the balloon is released, the negative pressure will move the glass ball toward the position of the maximum diameter of the inner hole II, thereby realizing the liquid passage.

[0020] Preferably, the connecting assembly includes a silicone plate, one end of which has a clip and the other end has an insertion hole, wherein the plug is inserted into the insertion hole and the clip is fitted onto the liquid outlet tube of the nasal irrigator.

[0021] Compared with the prior art, the beneficial effects of the present invention are:

[0022] In this invention, the use of manually adjustable negative pressure can effectively solve the problem of matching suction strength. In addition, the addition of an anti-backflow component can completely prevent the backflow of gas and liquid, improve patient comfort, ensure cleaning effect, eliminate hygiene hazards, and significantly reduce the risk of infection for users. At the same time, the added connecting components make it convenient for patients to match any nasal irrigation device, reducing the economic burden on patients. Furthermore, the nasal irrigation device can flexibly adjust the position of the plug to better match different nasal irrigators. Attached Figure Description

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0037] Example 1

[0038] Please see Figures 1 to 3 The present invention provides a technical solution: a nasal irrigation device with anti-backflow function, the nasal irrigation device including a cleaning part, a negative pressure part, and an anti-backflow component;

[0039] The cleaning section is connected to the negative pressure section, and the anti-backflow component is installed inside the negative pressure section;

[0040] An integrated liquid outlet pipe is provided on the cleaning section, and a plug 101 is provided on the side of the liquid outlet pipe. A connecting component 400 is connected between the plug 101 and the liquid outlet pipe.

[0041] The connecting assembly 400 consists of plate 401, plate 402, connecting screw 403, and spring 404.

[0042] Plate 1 401 and Plate 2 402 are arranged opposite to each other, and circular holes of different diameters are opened on the adjacent sides of the two. The diameter of the circular holes gradually decreases from the outside to the middle of the connecting component 400, so as to connect the liquid outlet tubes of different specifications of nasal irrigators 100. At the same time, the diameter of the innermost circular hole should be smaller than the diameter of the liquid outlet tubes on all nasal irrigators 100 on the market, so as to avoid the phenomenon that irregular liquid outlet tubes are smaller than the diameter of the circular holes and cannot be clamped.

[0043] The connecting screw 403 is fixed to the inner middle of the first plate 401, and the connecting screw 403 and the second plate 402 are movably connected through it. A nut is also provided on the outside of the second plate 402. The nut is screwed on the connecting screw 403. The distance between the first plate 401 and the second plate 402 is adjusted by adjusting the nut. This can increase the diameter of the circular hole to clamp liquid outlet pipes of various diameters, and can also clamp irregularly shaped liquid outlet pipes. The spring 404 is sleeved on the connecting screw 403, and its two ends abut against the first plate 401 and the second plate 402 respectively, so as to ensure quick adjustment of the first plate 401 and the second plate 402. It is worth noting that the function of the connecting component 400 is to connect the plug 101 and the liquid outlet pipe. In actual use, other structures that can achieve this function can also be used for connection.

[0044] In this embodiment, preferably, both the plug 101 and the liquid outlet tube on the nasal irrigator 100 are locked in the round holes on the first plate 401 and the second plate 402, and the plug 101 has a liquid outlet on its outer side.

[0045] In this embodiment, preferably, the negative pressure section includes a collection container 200 and a suction device 300; wherein the shape of the collection container 200 is not limited.

[0046] A short hose 102 connects the inlet of the collection container 200 to the plug 101, and the horizontal plane of the inlet of the collection container 200 is lower than the outlet of the plug 101.

[0047] A connector 201 is fixedly provided on the top of the collection container 200, and an inner hole 202, which is wider at the top and narrower at the bottom, is formed in the connector 201. The inner hole 202 is funnel-shaped, and an anti-backflow component is provided in the inner hole 202.

[0048] The aspirator 300 is connected to the connector 201. During use, one hand presses the nasal irrigator 100 to expel the liquid inside the nasal irrigator 100 into the nasal cavity through the outlet tube. The other hand pulls the aspirator 300, creating negative pressure inside the plug 101 and the collection container 200, and moving the glass bulb 203 towards the upper part of the inner hole 202. At this time, the plug 101, the collection container 200, and the aspirator 300 form a negative pressure passage, thereby aspirating the nasal mucus and the cleansing liquid together. The nasal mucus and liquid mixture flows into the collection container 200 through the short tube 102. After use, the aspirator 300 is released, and the gas flows back, pushing the glass bulb 203 to block the channel in the inner hole 202, thereby preventing the backflow of gas and liquid.

[0049] In this embodiment, preferably, the end of the suction device 300 is connected to a long hose 301, and the end of the long hose 301 is connected to a 302. The 302 is inserted into the connector 201, and the two are interference fit, thereby ensuring installation stability. In use, gas is transmitted through the long hose 301.

[0050] Example 2

[0051] Reference Figure 4 The difference from that in Embodiment 1 is that the end of the suction device 300 is inserted into the connector 201, and the axes of the two coincide, so as to achieve a direct connection. In use, after holding the suction device 300, the collection container 200 can be twisted up together, which is convenient to operate. In order to prevent the glass ball 203 from moving out of the inner hole 202, a thin rod is also provided at the top opening of the inner hole 202 to limit the glass ball 203.

[0052] Example 3

[0053] Reference Figure 5 and Figure 6 The difference from the above embodiments is that the negative pressure device includes a balloon 500, one end of which is connected to a short flexible tube 102. The balloon 500 is hollow. When the balloon 500 is pressed, the air inside the balloon 500 is discharged from the other end. Then the balloon 500 is released. At this time, the balloon 500 rebounds and generates negative pressure, thereby sucking out the mixture of mucus and cleaning liquid in the plug 101.

[0054] In this embodiment, preferably, an inner hole 501 is formed inside one end of the balloon 500. The inner diameter of the inner hole 501 gradually increases in the direction of the balloon 500. The anti-backflow component is a glass ball 203, which is disposed inside the inner hole 501. Similarly, to prevent the glass ball 203 from entering the balloon 500, a thin rod is also required at the opening of the inner hole 501 facing the balloon 500 for limiting. When the balloon 500 is pressed, the gas will push the glass ball 203 to block the inner hole 501, preventing gas backflow. When the balloon 500 is released, the negative pressure will move the glass ball 203 toward the position of the maximum diameter of the inner hole 501, thereby realizing the liquid passage.

[0055] Example 4

[0056] Reference Figure 7 The connecting component 400 includes a silicone plate 405, one end of which has a clip 406 and the other end has an insertion hole 407. The plug 101 is inserted into the insertion hole 407, and the clip 406 is fitted onto the liquid outlet tube of the nasal irrigator 100 to achieve the installation connection. The connecting component 400 has the characteristics of simple structure and easy processing.
