Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, and in particular to a disposable nasal rinser. Background Art

[0002] Factors such as rhinitis, upper respiratory tract infections, and exposure to high concentrations of dust particles are increasingly causing the accumulation of some harmful substances in the nasal cavity. These substances not only trigger allergic reactions, but may also aggravate the symptoms of diseases such as respiratory infections. As a simple and effective way, nasal cleaning can help relieve these discomforts and promote nasal health. Especially among patients with allergic rhinitis, nasal cleaning is widely used, and the increase in the number of patients has also driven the increase in the demand for nasal cleaning.

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

[0004] However, the nasal irrigators on the market are mainly divided into electric nasal irrigators and manual nasal irrigators. Although electric nasal irrigators have the advantage of efficient cleaning, they are large in size, rely on power when used, are expensive, and have poor overall portability, making it difficult for users to carry them when going out. Although manual nasal irrigators are relatively cheap in price, do not require power, and are easy to carry, they have low cleaning efficiency and require high water flow control when used, which may also cause inconvenience in use.

It is understood that if the device of the illustration is turned over and turned upside down, the component described as being "upper" will become the component "lower". Other relative terms such as "high", "low", "top", "bottom", "front", "back", "left", "right", etc. are also used to have similar meanings. When a structure is "on" other structures, it may mean that the structure is formed integrally on the other structure, or that the structure is "directly" disposed on the other structure, or that the structure is "indirectly" disposed on the other structure through another structure.

[0024] In the present invention, the terms "a", "an", "the", "said" and "at least one" are used to indicate the presence of one or more elements / components / etc.; the terms "comprising", "including" and "having" are used to express an open-ended inclusion and mean that additional elements / components / etc. may exist in addition to the listed elements / components / etc.

[0025] According to one aspect of the present invention, a disposable nasal rinse device is provided, referring to Figures 1 to 4 As shown, including: A clean water tank 10 is used to contain nasal wash liquid, and a water injection nasal wash head 11 is provided on the clean water tank, and the water injection nasal wash head 11 is used to inject the nasal wash liquid into one nasal cavity; A sewage tank 20 is provided with a water outlet nose wash head 21, and the water outlet nose wash head 21 is used to collect sewage discharged from the other nasal cavity, and the sewage tank 20 is a spring structure so that its volume can be adjusted by a spring mechanism; Among them, the water injection nasal wash head 11 is arranged adjacent to the water outlet nasal wash head 21, and the secondary nasal wash device has a use state. In the use state, the water injection nasal wash head 11 and the water outlet nasal wash head 21 are respectively inserted into and block the nasal cavities on both sides to form a closed cleaning channel.

[0026] It can be seen from the above technical solution that the present invention has at least one of the following advantages and positive effects: 1. The clean water tank 10 of the present invention is used to store clean nasal washing liquid, and the sewage tank 20 is used to collect sewage after washing. The clean water tank 10 and the sewage tank 20 are designed separately, so that the nasal washing liquid and the sewage will not mix, which can ensure the hygiene and effectiveness of the washing process and avoid secondary pollution; 2. The sewage tank 20 adopts a spring structure, which can not only improve the flexibility of use, but also optimize the cleaning effect by adjusting the pressure, ensuring that the nasal wash solution can flow into the nasal cavity with appropriate pressure, avoiding discomfort or incomplete cleaning caused by excessive or insufficient pressure; 3. The water injection nose wash tip 11 and the water outlet nose wash tip 21 are arranged adjacent to each other, and when in use, are inserted into and block the nasal cavities on both sides to form a closed cleaning channel, which can ensure that the nasal wash liquid effectively flows into one nasal cavity and flows out of the other nasal cavity, thereby avoiding the overflow of the nasal wash liquid and improving the cleaning efficiency; 4. The present invention has a simple structure and is easy to carry. It does not require complicated assembly or preparation work and can be used for nasal cleaning anytime and anywhere. It is suitable for daily use or travel.

[0027] The spring structure can automatically adjust the pressure during user operation to maintain a dynamic balance during the cleaning process. Specifically, in some embodiments, when the sewage tank 20 is pulled, the spring structure will be stretched, the volume of the sewage tank 20 will increase, and the internal pressure will decrease. At this time, a negative pressure will be formed in the sewage tank, so that the sewage discharged from the nasal cavity can be collected. In other embodiments, when the sewage tank 20 is squeezed, the spring structure will be compressed, the volume of the sewage tank 20 will decrease, and the internal pressure will increase; at this time, if the squeezing is stopped, the spring structure will gradually return to its original state, the volume of the sewage tank 20 will rebound, and the internal pressure will slowly increase. At this time, the sewage tank 20 can collect the sewage discharged from the nasal cavity at a lower pressure to avoid sewage backflow or discomfort due to excessive pressure.

[0028] In some embodiments, the spring structure can be further configured as an accordion structure, referring to Figure 1 and Figure 2As shown, at this point, the accordion structure can be compressed or pulled to increase or decrease its volume.

[0029] In addition, in order to ensure that the nasal wash liquid in the clean water tank 10 remains clean and uncontaminated, in some embodiments, a cap 12 can be provided on the water-filled nasal wash head 11 to seal the water-filled nasal wash head 11 and the clean water tank 10 when not in use, so as to prevent external dust, bacteria or other pollutants from entering the clean water tank 10 or the water-filled nasal wash head 11, thereby ensuring the cleanliness and hygiene of the nasal wash liquid. In addition, due to the presence of the cap 12, the nasal wash device can be made more compact when not in use, and is easy to put into a bag or carry with you, and is suitable for travel, outdoor activities or daily commuting.

[0030] On this basis, the cap 12 can also be designed as a structure that is easy to disassemble, so that the cap 12 can be easily removed from the water-filling nose washing head 11, which is simple and quick to operate and improves the convenience of use. After disassembly, the groove part of the cap 12 can be matched with the protrusion of the water-filling nose washing head 11, so that the water-filling nose washing head 11 is secondary sealed when the nose washing liquid is not used up at one time.

[0031] In some embodiments, reference Figure 1 and Figure 2 As shown, it can also be designed that the side of the clean water tank 10 away from the dirty water tank 20 has a first bottom plate 13; the side of the dirty water tank 20 away from the clean water tank 10 has a second bottom plate 22; the secondary nasal rinser also includes an elastic bandage 30 (not shown in the figure), and the elastic bandage 30 surrounds the clean water tank 10 and the dirty water tank 20 to limit the movement range of the first bottom plate 13 relative to the second bottom plate 22.

[0032] By setting the first bottom plate 13 and the second bottom plate 22, and using the elastic bandage 30 to surround the clean water tank 10 and the sewage tank 20, the relative movement between the two can be effectively restricted, the volume of the clean water tank 10 and the sewage tank 20 can be restricted and fixed, and the clean water tank 10 and the sewage tank 20 can be ensured to remain stable during use, avoiding structural instability due to external pressure or collision, thereby improving the durability and service life of the disposable nasal rinser.

[0033] In this embodiment, reference Figure 5 As shown, a partition 40 can also be provided between the clean water tank 10 and the dirty water tank 20, and the partition 40 can be moved between the clean water tank 10 and the dirty water tank 20. At this time, when using the disposable nasal rinser, one hand fixes the partition 40, and the other hand pulls the second bottom plate 22 of the dirty water tank 20 away from the partition 40. At this time, the elastic bandage 30 will drive the first bottom plate 13 to approach the partition 40. At this time, the area of ​​the clean water tank 10 becomes smaller, and the area of ​​the dirty water tank 20 becomes larger. The clean water tank 10 generates positive pressure to squeeze the nasal wash liquid into one nasal cavity, and the dirty water tank 20 generates negative pressure to absorb the dirty water flowing out of the other nasal cavity.

[0034] In other embodiments, a limiting column (not shown in the figure) can be further provided between the first bottom plate 13 and the second bottom plate 22, and the limiting column passes through the clean water tank 10 and the dirty water tank 20 so that one end thereof abuts against the first bottom plate 13 and the other end abuts against the second bottom plate 22.

[0035] Here, the limiting column may be used to replace the elastic bandage 30, or the limiting column may be provided on the basis of providing the elastic bandage 30, so as to further enhance the structural stability.

[0036] When the limiting column solution is adopted, a partition 40 can also be set between the clean water tank 10 and the sewage tank 20. Similarly, when using the disposable nasal wash device, one hand fixes the partition 40, and the other hand pulls the second bottom plate 22 of the sewage tank 20 to move away from the partition 40. At this time, due to the presence of the limiting column, the distance between the first bottom plate 13 and the second bottom plate 22 is constant, so the first bottom plate 13 will move toward the direction close to the partition 40. At this time, the area of ​​the clean water tank 10 becomes smaller, and the area of ​​the sewage tank 20 becomes larger. The clean water tank 10 generates positive pressure to squeeze the nasal wash solution into one nasal cavity, and the sewage tank 20 generates negative pressure to absorb the sewage flowing out of the other nasal cavity.

[0037] In some embodiments, in order to enhance structural rigidity, two limit columns can be set, and the two limit columns can be set at intervals. For example, two can be set in the vertical direction, and two can be set in the horizontal direction. Of course, four limit columns can also be set, and an array of four limit columns can be set so that there are two in both the horizontal direction and the vertical direction.

[0038] In addition, reference Figure 3 As shown, a first one-way duckbill valve 50 can also be provided on the partition 40 , the air inlet end of the first one-way duckbill valve 50 is connected to the water outlet nose wash head 21 , and the air outlet end thereof is located in the sewage tank 20 .

[0039] The design of the first one-way duckbill valve 50, on the one hand, allows the airflow to flow only from the water outlet nasal wash head 21 to the sewage tank 20, but not in the reverse direction, thereby ensuring that during the use of the nasal wash device, the liquid or gas in the sewage tank 20 is prevented from flowing back to the water outlet nasal wash head 21, thereby improving the patient's comfort and avoiding cross contamination; on the other hand, the first one-way duckbill valve 50 helps to maintain an appropriate pressure balance between the water outlet nasal wash head 21 and the sewage tank 20, preventing system instability or equipment damage caused by pressure difference, and ensuring the stability of system operation.

[0040] Of course, reference Figure 1 , Figure 2 and Figure 4As shown, a second one-way duckbill valve 60 may also be provided on the sewage bin 20 , wherein the air inlet end of the second one-way duckbill valve 60 is located outside the sewage bin 20 , and the air outlet end thereof is located inside the sewage bin 20 .

[0041] The air inlet end of the second one-way duckbill valve 60 is located outside the sewage tank 20, which can prevent the outside air from entering the sewage tank 20 and avoid the invasion of external pollutants; and its air outlet end is located inside the sewage tank 20, which can timely discharge the internal gas when the air pressure changes in the sewage tank 20, maintain the air permeability and stability of the sewage tank 20, ensure the normal operation of the sewage tank 20 and prevent the sewage tank 20 from being damaged due to excessive air pressure. In addition, this design can also effectively prevent the influence of reverse airflow and improve the safety and reliability of the system.

[0042] In addition, reference 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 clean water tank 10 and / or the dirty water tank 20 .

[0043] In this way, by increasing the cross-sectional area of ​​the partition 40, the gas flow efficiency between the clean water tank 10 and the sewage tank 20 can be effectively improved, and the airflow resistance can be reduced, thereby ensuring that the clean water tank 10 and the sewage tank 20 maintain a good air pressure state during use, and avoiding the flow of the nasal wash solution or the absorption of sewage due to poor airflow. In addition, this design can also enhance the stability of the overall structure, ensure the effective isolation of the partition 40 between the clean water tank 10 and the sewage tank 20, and avoid the negative impact caused by structural imbalance. Through the reasonable area setting of the partition 40, the pressure difference between the clean water tank 10 and the sewage tank 20 can be better controlled, the use effect and comfort of the disposable nasal wash can be improved, and at the same time, the damage to the structure by external pressure or collision can be avoided, thereby extending the service life and durability of the nasal wash can.

[0044] In order to further improve the portability of the nasal rinser, reduce its production cost, and thus further reduce its use cost, the material of the clean water tank 10 and the dirty water tank 20 can be plastic. Plastic materials are light, corrosion-resistant, easy to process and mold, and can effectively reduce the overall weight of the disposable nasal rinser and improve the convenience of users.

[0045] In summary, according to the present invention, a nasal washer can be designed to be compact, portable and disposable.

[0046] It should be understood that the present invention does not limit its application to the detailed structure and arrangement of the components proposed by the present invention. The present invention can have other embodiments and can be implemented and executed in a variety of ways. The aforementioned variations and modifications fall within the scope of the present invention. It should be understood that the present invention disclosed and defined by the present invention extends to all alternative combinations of two or more individual features mentioned or evident in the text and / or the accompanying drawings. All these different combinations constitute multiple alternative aspects of the present invention. The embodiments described in the present invention illustrate the best mode known for implementing the present invention and will enable those skilled in the art to utilize the present invention.
