Description

Technical Field

[0001] This utility model relates to the field of medical device technology, and in particular to a disposable nasal irrigator. Background Technology

[0002] With changes in the living environment and increased air pollution, factors such as rhinitis, upper respiratory tract infections, and exposure to high concentrations of dust particles are increasingly leading to the accumulation of harmful substances in the nasal cavity. These substances can not only trigger allergic reactions but also exacerbate symptoms of respiratory infections and other diseases. Nasal irrigation, as a simple and effective method, can help relieve these discomforts and promote nasal health. Nasal irrigation is particularly widely used among patients with allergic rhinitis, and the increasing number of patients has driven up the demand for it.

[0003] Numerous studies have shown that nasal irrigation can effectively shorten the course of illness and alleviate related symptoms. Some studies also indicate that nasal irrigation after a cold can not only effectively reduce the viral load in the nasal cavity but also reduce nasal congestion and relieve discomfort during a cold. Therefore, nasal irrigation has gradually become an important part of people's daily care.

[0004] However, nasal irrigators on the market are mainly divided into electric and manual nasal irrigators. While electric nasal irrigators have the advantage of high cleaning efficiency, they are relatively large, require a power source, are expensive, and have poor overall portability, making them inconvenient for users to carry when going out. Manual nasal irrigators, on the other hand, are relatively cheaper and do not require a power source, making them easy to carry, but their cleaning efficiency is lower, and they require more precise control of the water flow, which may also lead to inconvenience in use.

[0044] According to one aspect of the present invention, a disposable nasal rinser is provided, with reference to... Figures 1 to 4 As shown, it includes:

[0045] The water tank 10 is used to hold nasal wash solution and is equipped with a water-injecting nasal wash head 11, which is used to inject the nasal wash solution into one nasal cavity.

[0046] The wastewater tank 20 is equipped with a water-discharging nasal tip 21, which is used to collect wastewater discharged from the other nasal cavity. The wastewater tank 20 is a spring structure so that its volume can be adjusted by a spring mechanism.

[0047] The water-filling nasal irrigation tip 11 and the water-discharging nasal irrigation tip 21 are arranged adjacent to each other. The disposable nasal irrigator is in use. In the use state, the water-filling nasal irrigation tip 11 and the water-discharging nasal irrigation tip 21 are respectively inserted into and block the two sides of the nasal cavity to form a closed cleaning channel.

[0048] As can be seen from the above technical solution, this utility model possesses at least one of the following advantages and positive effects:

[0049] 1. The clean water tank 10 of this utility model is used to store clean nasal wash solution, while the wastewater tank 20 is specifically used to collect wastewater after washing. The clean water tank 10 and the wastewater tank 20 are designed separately so that the nasal wash solution and wastewater will not mix, which can ensure the hygiene and effectiveness of the washing process and avoid secondary pollution.

[0050] 2. The wastewater tank 20 adopts a spring structure, which not only improves the flexibility of use, but also optimizes the cleaning effect by adjusting the pressure, ensuring that the nasal rinse solution can flow into the nasal cavity with appropriate pressure, avoiding discomfort or incomplete cleaning caused by excessive or insufficient pressure.

[0051] 3. The water-filling nasal irrigation tip 11 and the water-discharging nasal irrigation tip 21 are arranged adjacent to each other and are inserted into and block both nasal cavities during use to form a closed cleaning channel. This ensures that the nasal irrigation solution flows effectively from one nasal cavity and flows out from the other nasal cavity, preventing the nasal irrigation solution from overflowing and improving cleaning efficiency.

[0052] 4. This utility model has a simple structure, is easy to carry, requires no complicated assembly or preparation, and can be used for nasal cleaning anytime and anywhere, making it suitable for daily use or travel.

[0053] The spring structure can automatically adjust the pressure during user operation to maintain dynamic balance in the cleaning process.

[0054] Specifically, in some embodiments, when the wastewater chamber 20 is pulled, the spring structure is stretched, the volume of the wastewater chamber 20 increases, and the internal pressure decreases. At this time, a negative pressure is formed inside the wastewater chamber, thus collecting the wastewater discharged from the nasal cavity. In other embodiments, when the wastewater chamber 20 is squeezed, the spring structure is compressed, the volume of the wastewater chamber 20 decreases, and the internal pressure increases. When the squeezing is stopped, the spring structure gradually returns to its original shape, the volume of the wastewater chamber 20 rebounds, and the internal pressure slowly increases. At this time, the wastewater chamber 20 can collect the wastewater discharged from the nasal cavity at a lower pressure, avoiding backflow of wastewater or discomfort due to excessive pressure.

[0055] In some embodiments, the spring structure can be further configured as a bellows structure, see reference. Figure 1 and Figure 2 As shown, the accordion structure can be compressed or expanded to increase or decrease its volume. In addition, to ensure the nasal rinse solution in the water tank 10 remains clean and uncontaminated, in some embodiments, a cap 12 can be provided on the water-filled nasal rinse head 11 to seal the water-filled nasal rinse head 11 and the water tank 10 when not in use, preventing external dust, bacteria, or other contaminants from entering the water tank 10 or the water-filled nasal rinse head 11, thus ensuring the cleanliness and hygiene of the nasal rinse solution. Furthermore, the presence of the cap 12 makes the nasal irrigator more compact when not in use, making it easy to put in a bag or carry, suitable for travel, outdoor activities, or daily commutes.

[0056] Furthermore, the cap 12 can be designed with an easy-to-disassemble structure, allowing it to be easily removed from the nasal irrigation tip 11, making the operation simple and quick and improving ease of use. After disassembly, the grooved portion of the cap 12 can fit into the protrusion of the nasal irrigation tip 11, so as to create a secondary seal for the nasal irrigation tip 11 when the nasal irrigation solution is not used up at one time.

[0057] In some implementations, reference Figure 1 and Figure 2 As shown, the clean water tank 10 can also be designed with a first base plate 13 on the side away from the wastewater tank 20; the wastewater tank 20 can be designed with a second base plate 22 on the side away from the clean water tank 10; the nasal irrigator also includes an elastic bandage 30 (not shown in the figure), which surrounds the clean water tank 10 and the wastewater tank 20 to limit the range of motion of the first base plate 13 relative to the second base plate 22.

[0058] By setting a first base plate 13 and a second base plate 22, and using an elastic bandage 30 to surround the clean water tank 10 and the waste water tank 20, the relative movement between the two can be effectively restricted, the volume of the clean water tank 10 and the waste water tank 20 can be limited and fixed, and the clean water tank 10 and the waste water tank 20 can be kept stable during use, avoiding structural instability caused by external pressure or collision, thereby improving the durability and service life of the disposable nasal irrigator.

[0059] In this embodiment, reference Figure 5 As shown, a partition 40 can also be installed between the clean water tank 10 and the wastewater tank 20, and the partition 40 can move between the clean water tank 10 and the wastewater tank 20. At this time, when using the disposable nasal irrigator, one hand holds the partition 40, and the other hand pulls the second bottom plate 22 of the wastewater tank 20 away from the partition 40. At this time, the elastic bandage 30 will drive the first bottom plate 13 closer to the partition 40. At this time, the area of ​​the clean water tank 10 becomes smaller and the area of ​​the wastewater tank 20 becomes larger. The clean water tank 10 generates positive pressure to squeeze the nasal irrigation solution into one nasal cavity, and the wastewater tank 20 generates negative pressure to absorb the wastewater flowing out of the other nasal cavity.

[0060] In other embodiments, a limiting post (not shown in the figure) may be provided between the first base plate 13 and the second base plate 22. The limiting post passes through the clean water tank 10 and the sewage tank 20, so that one end of the limiting post abuts against the first base plate 13 and the other end abuts against the second base plate 22.

[0061] Here, a limiting post can be used instead of the elastic bandage 30, or a limiting post can be set on the basis of setting the elastic bandage 30 to further enhance the structural stability.

[0062] When using the limiting post scheme, a partition 40 can also be set between the clean water tank 10 and the waste water tank 20. Similarly, when using the disposable nasal irrigator, one hand holds the partition 40, and the other hand pulls the second bottom plate 22 of the waste water tank 20 away from the partition 40. At this time, due to the presence of the limiting post, the distance between the first bottom plate 13 and the second bottom plate 22 is constant. Therefore, the first bottom plate 13 will move towards the partition 40. At this time, the area of ​​the clean water tank 10 becomes smaller and the area of ​​the waste water tank 20 becomes larger. The clean water tank 10 generates positive pressure to squeeze the nasal irrigation liquid into one nasal cavity, and the waste water tank 20 generates negative pressure to absorb the waste water flowing out of the other nasal cavity.

[0063] In some implementations, to enhance structural rigidity, two limiting posts can be provided, spaced apart. For example, two can be provided in the vertical direction or in the horizontal direction. Of course, four can also be provided in an array of four limiting posts, so that there are two in both the horizontal and vertical directions.

[0064] In addition, refer to Figure 3 As shown, a first one-way duckbill valve 50 can also be provided on the partition 40. The air inlet of the first one-way duckbill valve 50 is connected to the water-discharging nose tip 21, and its air outlet is located inside the sewage tank 20.

[0065] The design of the first one-way duckbill valve 50 ensures that airflow can only flow from the water-filled nasal tip 21 to the wastewater tank 20, and cannot flow in the opposite direction. This prevents liquid or gas in the wastewater tank 20 from flowing back to the water-filled nasal tip 21 during use, improving patient comfort and avoiding cross-contamination. On the other hand, the first one-way duckbill valve 50 helps maintain a proper pressure balance between the water-filled nasal tip 21 and the wastewater tank 20, preventing system instability or equipment damage caused by pressure differences and ensuring the stability of system operation.

[0066] Of course, for reference Figure 1 , Figure 2 and Figure 4 As shown, a second one-way duckbill valve 60 can also be provided on the sewage tank 20. The air inlet of the second one-way duckbill valve 60 is located outside the sewage tank 20, and its air outlet is located inside the sewage tank 20.

[0067] The air inlet of the second one-way duckbill valve 60 is located outside the sewage tank 20, preventing outside air from entering and avoiding the intrusion of external pollutants. Its air outlet is located inside the sewage tank 20, allowing for timely release of internal gas when pressure changes occur within the tank, maintaining ventilation and stability, ensuring normal operation, and preventing damage due to excessive pressure. Furthermore, this design effectively prevents the influence of reverse airflow, enhancing system safety and reliability.

[0068] In addition, refer to Figure 1 and Figure 2 As shown, the cross-sectional area of ​​the partition 40 can also be designed to be larger than the cross-sectional area of ​​the clear water tank 10 and / or the sewage tank 20.

[0069] By increasing the cross-sectional area of ​​the partition 40, the gas flow efficiency between the clean water tank 10 and the wastewater tank 20 can be effectively improved, reducing airflow resistance. This ensures that the clean water tank 10 and the wastewater tank 20 maintain a good air pressure state during use, preventing the flow of nasal irrigation solution or the absorption of wastewater from being affected by poor airflow. Furthermore, this design enhances the stability of the overall structure, ensuring effective isolation between the clean water tank 10 and the wastewater tank 20 by the partition 40, avoiding negative impacts caused by structural imbalances. Through a reasonable partition 40 area setting, the pressure difference between the clean water tank 10 and the wastewater tank 20 can be better controlled, improving the effectiveness and comfort of the single-use nasal irrigator, while preventing damage to the structure from external pressure or impacts, thereby extending the service life and durability of the nasal irrigator.

[0070] To further improve the portability of the nasal irrigator and reduce its production costs, thereby further lowering its usage costs, the clean water tank 10 and the wastewater tank 20 can be made of plastic. Plastic materials are lightweight, corrosion-resistant, easy to process and mold, which can effectively reduce the overall weight of the single-use nasal irrigator and improve user convenience.

[0071] In summary, according to this utility model, a nasal irrigator can be designed to be small in size, easy to carry, and disposable.

[0072] It should be understood that this invention is not limited to the detailed structure and arrangement of the components proposed in this invention. This invention can have other embodiments and can be implemented and performed in various ways. The foregoing variations and modifications fall within the scope of this invention. It should be understood that the invention disclosed and defined herein extends to all alternative combinations of two or more individual features mentioned or apparent in the text and / or drawings. All these different combinations constitute multiple alternative aspects of this invention. The embodiments described herein illustrate the best known mode for implementing this invention and will enable those skilled in the art to utilize this invention.
