Description

Technical Field

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

[0002] Nasal irrigation is a common nasal care method, widely used in the treatment of nasal diseases and daily nasal cleaning and health care. It can effectively remove dirt, allergens, inflammatory secretions, etc. from the nasal cavity, improve nasal ventilation, reduce nasal inflammation, and promote the recovery of normal physiological function of the nasal mucosa.

[0003] In existing technologies, there are many types of nasal irrigators. Traditional nasal irrigators mostly adopt simple squeeze or gravity designs. Squeeze irrigators rely on manually squeezing the container to generate flushing pressure, but this method makes it difficult to precisely control the flow rate and pressure of the flushing fluid. This can easily result in the flushing fluid flow being too fast or too slow. Too fast a flow rate may cause problems such as choking or ear discomfort, while too slow a flow rate will not achieve the desired flushing effect. Gravity irrigators are relatively stable, but the flow rate of the flushing fluid is greatly affected by the height of the container, and it is also difficult to achieve precise adjustment. In addition, when using these traditional irrigators in cold weather, the icy flushing fluid entering the nasal cavity directly can cause strong discomfort to the user and may even cause vasoconstriction of the nasal mucosa, affecting the flushing effect and nasal health. Moreover, the existing nasal insert design is not reasonable enough, and may cause some degree of damage to the nasal mucosa during insertion, affecting the user experience and the normal physiological structure of the nasal cavity. Utility Model Content

[0004] The present invention aims to solve, to at least some extent, the technical problems in the above-mentioned technologies.

[0005] Therefore, this utility model discloses a nasal irrigator, comprising:

[0006] Infusion bottles are used to store flushing fluids;

[0007] An infusion tube, one end of which is inserted into the mouth of the infusion bottle;

[0008] A peristaltic pump, which is mounted on the infusion tubing, is used to control the flow rate of the flushing fluid;

[0009] A heating jacket, which is disposed on the infusion tube, is used to heat the flushing fluid;

[0010] A nasal inserter is located at the other end of the infusion tube.

[0011] In addition, the nasal irrigator disclosed in this utility model may also have the following additional technical features:

[0012] In one embodiment of this utility model, the nasal cavity insert has a stepped structure and is provided with multiple cylindrical parts that are connected in sequence and whose cross-sectional areas decrease in sequence.

[0013] The cylindrical part at one end has the largest cross-sectional area, while the cylindrical part at the other end has the smallest cross-sectional area.

[0014] The end of the cylindrical part with the largest cross-sectional area is connected to the infusion tube, and the end of the cylindrical part with the smallest cross-sectional area is used for insertion into the nasal cavity.

[0015] In one embodiment of this utility model, the side of the heating sleeve that contacts the infusion tube is provided with heat-insulating foam.

[0016] In one embodiment of this utility model, both the infusion bottle and the infusion tube are transparent, and the outer wall of the infusion bottle is provided with graduations.

[0017] In one embodiment of this utility model, it further includes:

[0018] A flow regulating valve, disposed on the infusion tubing between the peristaltic pump and the nasal insert, is used to control the flow rate of the irrigation fluid.

[0019] In one embodiment of this utility model, the nasal insert is made of silicone.

[0020] The nasal irrigator disclosed in this utility model can precisely control the flow rate of the irrigating fluid through a peristaltic pump, avoiding choking, ear discomfort, or poor irrigating effect. It also overcomes the shortcomings of gravity irrigators, where the flow rate is greatly affected by the height of the container and is difficult to adjust precisely. The heating sleeve can heat the irrigating fluid, preventing the cold irritation of the nasal mucosa when used in cold weather, avoiding vasoconstriction of the nasal mucosa, thus ensuring the irrigating effect and nasal health, and improving user comfort. The nasal insert has a stepped structure, with multiple cylindrical sections of successively decreasing cross-sectional area. During insertion into the nasal cavity, it gradually transitions from the end with the larger cross-sectional area to the end with the smallest cross-sectional area, reducing the possibility of damage to the nasal mucosa, protecting the normal physiological structure of the nasal cavity, and improving the user experience.

[0021] Additional features and advantages of this invention will be set forth in the description which follows, or may be learned by practicing this invention. Attached Figure Description

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0029] The nasal irrigator disclosed in this utility model will now be described with reference to the accompanying drawings.

[0030] like Figure 1 , Figure 2 and Figure 3 As shown, the nasal irrigator of this utility model mainly consists of an infusion bottle 1, an infusion tube 2, a peristaltic pump 3, a heating jacket 4, a nasal cavity insert 5, and a flow regulating valve 6.

[0031] Infusion bottle 1 is used to store flushing fluid. It is transparent and has graduations on the outer wall to make it easy for users to observe the remaining amount of flushing fluid.

[0032] One end of the infusion tube 2 is inserted into the mouth of the infusion bottle 1. It is transparent to ensure a tight connection and prevent leakage of the flushing fluid.

[0033] The peristaltic pump 3 is installed on the infusion tube 2 to precisely control the flow rate of the flushing fluid. Its working principle is to push the flushing fluid forward by alternately squeezing and releasing the infusion tube 2, thereby achieving precise control of the flow rate.

[0034] The heating sleeve 4 is installed on the infusion tube 2, and the side in contact with the infusion tube 2 is provided with heat-insulating foam, which can effectively heat the flushing fluid, prevent heat loss too quickly, and prevent the user from being burned when touching the heating sleeve 4.

[0035] The nasal insert 5 is located at the other end of the infusion tube 2. It is made of silicone, which has good flexibility and biocompatibility. The nasal insert 5 has a stepped structure and has multiple cylindrical parts that are connected in sequence and whose cross-sectional area decreases in sequence. The end with the largest cross-sectional area of ​​the cylindrical part is connected to the infusion tube 2, and the end with the smallest cross-sectional area is used for insertion into the nasal cavity. This design allows the nasal cavity to gradually transition from the end with the larger cross-sectional area to the end with the smallest cross-sectional area during insertion, reducing the possibility of damage to the nasal mucosa.

[0036] The flow regulating valve 6 is installed on the infusion tube 2 between the peristaltic pump 3 and the nasal insert 5, which can further assist in controlling the flow rate of the irrigation fluid. Users can fine-tune the flow rate according to their own needs.

[0037] Specifically, users need to make necessary preparations before using the product;

[0038] First, select the appropriate rinsing solution according to the need for rinsing the nasal cavity and pour it into infusion bottle 1. Accurately measure the amount of rinsing solution through the scale on the outer wall of infusion bottle 1.

[0039] Next, tightly insert one end of the infusion tube 2 into the mouth of the infusion bottle 1, and ensure that there is no leakage between the infusion bottle 1 and the infusion tube 2;

[0040] Then, connect the nasal insert 5 to the other end of the infusion tube 2, and at the same time check whether the connection of each component is firm, and whether the peristaltic pump 3, heating jacket 4 and flow regulating valve 6 are working properly;

[0041] If the nasal irrigator is used in a cold environment, turn on the heating jacket 4. After the heating jacket 4 starts working, it will heat the irrigating fluid in the infusion tube 2. The heat insulation foam can transfer the heat to the irrigating fluid more concentratedly and improve the heating efficiency.

[0042] Users can roughly feel whether the temperature of the rinsing solution is suitable by touching the infusion tube 2, so as to avoid the rinsing solution being too hot and burning the nasal mucosa. After the rinsing solution reaches the appropriate temperature, turn off the heating jacket 4 or keep it running at a low power to maintain the temperature.

[0043] Start the peristaltic pump 3. Based on the user's comfort and the tolerance of the nasal cavity, the flow rate of the rinsing solution can be precisely controlled by the adjustment button of the peristaltic pump 3 itself and the flow regulating valve 6. Generally, the initial flow rate can be set a little slower to allow the user to adapt, and then adjusted appropriately according to the actual situation. For example, for users with more sensitive nasal cavities, the flow rate can be controlled at 30-50 ml per minute. For users with better nasal cavity conditions and who can adapt to a faster flow rate, the flow rate can be increased to 50-80 ml per minute.

[0044] The user tilts their head slightly forward and gently inserts the end of the nasal insert 5 with the smallest cross-sectional area into one nostril. The insertion depth should be comfortable and not produce a strong foreign body sensation, generally about 2 to 3 centimeters.

[0045] Then, open the flow regulating valve 6 to allow the rinsing solution to slowly flow into the nasal cavity. The rinsing solution will pass through the infusion tube 2, peristaltic pump 3, heating jacket 4, and flow regulating valve 6 in sequence, and finally enter the nasal cavity through the nasal cavity insert 5 to rinse the nasal cavity.

[0046] During the rinsing process, users can breathe gently and avoid excessive tension. The rinsing solution will carry away dirt, allergens, inflammatory secretions, etc. from the nasal cavity and flow out from the other nasal cavity or mouth.

[0047] After rinsing one nasal cavity, close the flow regulating valve 6, remove the nasal insert 5 from the nasal cavity, rest for a while, and then rinse the other nasal cavity in the same way.

[0048] After nasal irrigation is complete, turn off peristaltic pump 3, remove infusion tube 2 from infusion bottle 1, and pour out the remaining irrigation solution;

[0049] Then, rinse the infusion bottle 1, infusion tube 2, nasal insertion device 5 and other parts with clean water to ensure that there is no rinse solution residue and to avoid the growth of bacteria. After rinsing, dry each part and store it in a dry and clean place for future use.

[0050] In summary, the nasal irrigator disclosed in this utility model can precisely control the flow rate of the irrigating fluid through the peristaltic pump 3, avoiding choking, ear discomfort, or poor irrigating effect. It also overcomes the shortcomings of gravity irrigators, where the flow rate is greatly affected by the height of the container and is difficult to adjust precisely. The heating sleeve 4 can heat the irrigating fluid, preventing the cold irritation of the nasal mucosa when used in cold weather, avoiding vasoconstriction of the nasal mucosa, thus ensuring the irrigating effect and nasal health, and improving user comfort. The nasal insert 5 has a stepped structure, with multiple cylindrical parts with progressively decreasing cross-sectional areas. During insertion into the nasal cavity, it gradually transitions from the end with the larger cross-sectional area to the end with the smallest cross-sectional area, reducing the possibility of damage to the nasal mucosa, protecting the normal physiological structure of the nasal cavity, and improving the user experience.

[0051] Although embodiments of the present invention have been shown and described above, it is understood that the above embodiments are exemplary and should not be construed as limiting the present invention. Those skilled in the art can make changes, modifications, substitutions and variations to the above embodiments within the scope of the present invention.
