[0046] Embodiment 1

[0047] As Figs. 1-3 shown, the embodiments of the present application provide a nasal cavity flusher, which comprises: a bottle body 1, a flush head 2 and a conduit 3.

For example, selected from one or a combination of polyethylene terephthalate (PET), polypropylene (PP), high-density polyethylene (HDPE), low-density polyethylene (LDPE), etc. Preferably, low-density polyethylene (LDPE). The diameter of the bottle mouth 12 is determined according to the convenience of adding nasal saline / powder and pure water. At present, some bottle bodies have obvious plastic smell or peculiar smell and are not easy to remove. The bottle body is too hard to be squeezed, and the bottle body cannot quickly rebound when squeezed and used, and the elasticity is insufficient, so that the flushing pressure is too large or insufficient. The utility model selects a high safety level elastic material, the bottle body can achieve good elasticity, easily squeezed and quickly rebounded, and convenient to use.

[0053] The flushing head 2 comprises a connecting part 21 and a flushing part 22, the connecting part 21 is connected with the bottle mouth 12, and the water outlet 20 is arranged on the flushing part 22.

As another implementation scenario, the protruding strips 23 are in the shape of a polygon, such as a hexagon or an octagon, and the outer side of the protruding strips 23 is preferably a smooth surface.

[0056] Optionally, the flushing part 22 is gradually arranged in a converging manner from one end to the other end of the connecting part 21. The flushing part 22 is approximately in the shape of a cone. The flushing part 22 can be in full and effective contact with the nostrils of adults or children and tightly and closely sealed, thereby reducing water leakage or splashing.

[0057] Optionally, the flushing head 2 can be selected from one or a combination of polyethylene terephthalate (PET), polypropylene (PP), high-density polyethylene (HDPE), low-density polyethylene (LDPE), etc. Preferably, polypropylene (PP).

[0058] Optionally, the water outlet 20 has a suitable hole diameter, such as 4mm-5mm, which can ensure that the water flow and water pressure are appropriate.

[0059] Optionally, the diameter of the flushing portion 22 near one end of the connecting portion 21 is smaller than the diameter of the connecting portion 21.

[0063] Optionally, the guide pipe 3 is made of food-grade or safer-grade silica gel material.

[0064] In an embodiment, a first water level line 13 is provided on the bottle body 11. The first water level line 13 is the maximum water level line of the bottle, which is provided near the bottle mouth 12. The first water level line 13 can be used to indicate the maximum volume after adding the nasal saline / powder and the purified water, and can be used to intuitively judge the amount of water added, so as to quickly prepare the normal saline or the solution close to isotonic and isotonic concentration for nasal irrigation.

[0065] Optionally, the first water level line 13 can be provided at a bottle volume of 250ml or 240ml. Preferably, the bottle volume is 240ml.

[0066] In an embodiment, a second water level line 14 is further provided on the bottle body 11, and the second water level line 14 is located below the first water level line 13. The second water level line 14 is a temperature adjustment prompt water level line, i.e. a cold and hot water proportion boundary line, which is used to indicate the amount of normal temperature purified water added. The volume between the second water level line 14 and the first water level line 13 is used to add the commonly used heated purified water at home, such as boiled purified water or hot water from a water dispenser. After adding cold water and hot water according to the water level line and mixing, a comfortable warm water (temperature 35℃-40℃) for nasal irrigation can be quickly obtained. The prepared irrigation solution can pass through or not pass through a 0.22 micron micropore filtration system according to the actual situation.

[0067] Currently, temperature control of rinsing solutions is inconvenient. This invention, however, utilizes microwave-resistant materials and a water level design to easily and quickly prepare rinsing solutions at suitable temperatures. In practical use, if the temperature of the rinsing solution is below 30°C, the water temperature is too low and may cause cold stimulation and discomfort; while a temperature above 45°C may damage the nasal mucosa. Currently, rinsing bottles are not convenient for users to quickly prepare solutions at a comfortable temperature (between 35°C and 40°C). This invention cleverly uses water level control to easily and quickly prepare rinsing solutions at suitable temperatures. Furthermore, due to the use of microwave-resistant materials, the bottle containing the prepared solution can be microwaved to a comfortable temperature. With two heating methods, the ease of solution preparation is greatly simplified, improving user compliance. The microwave-resistant materials also facilitate microwave sterilization.

[0068] Example 2

[0069] Based on Example 1, and referring to Figs. 1-3 As shown, in this embodiment, one or more bends 4 are provided around the outer periphery of the conduit 3.

[0070] The number of bends 4 can be flexibly configured as needed. In this embodiment, an even number is preferred, with the even number of bends 4 arranged in pairs in a symmetrical or staggered manner.

[0072] Optionally, the bend 4 includes an inclined section 41 and a bent section 42. One end of the inclined section 41 is connected to the conduit 3. The inclined section 41 is inclined outward from one side of the conduit 3. The end of the inclined section 41 away from the conduit 3 is connected to one end of the bent section 42. The other end of the bent section 42 is connected to the conduit 3.

[0073] Optionally, two bends 4 are symmetrically arranged on both sides of the conduit 3.

[0074] A bend 4 is installed around the outer periphery of the tubing 3, with the inner cavity of the bend 4 connected to the inner cavity of the tubing 3. During use, the prepared solution enters from the bottom inlet of the tubing 3, and a portion of the solution is introduced into the bend 4. The solution then passes through the tubing 3 and the bend 4 before exiting from the top outlet of the tubing 3 into the outlet 20, from which it is sprayed out. The introduction of the solution through the tubing 3 and the bend 4 not only reduces residual solution in the bottle but also prevents backflow or reverse flow during nasal irrigation, avoiding contamination of the remaining solution. Furthermore, it allows for secondary mixing of the solution during use, ensuring more uniform mixing of the saline or drug solution and a more uniform solution temperature.

[0075] Embodiment 3

[0076] Referring to Fig. 4 As shown in the figure, different from Embodiment 2, in this embodiment, the two elbow pipes 4 are staggered. Alternatively, the end of the curved section of the elbow pipe on one side is connected between the inclined section and the curved section of the elbow pipe on the other side, i.e. the elbow pipes 4 on both sides of the conduit 3 are arranged in overlapping manner.

[0080] Alternatively, the telescopic bending section 32 is arranged in the middle of the conduit 3, i.e. in this embodiment, the bending zone is the telescopic bending section 32 formed in the middle of the conduit 3.

[0081] In this embodiment, the telescopic bending section 32 can increase the elastic telescopic range of the conduit 3, and when the flushing head 2 is connected with the bottle body 1, the lower end of the conduit 3 can be in full contact with the bottle bottom, and the lower end of the conduit 3 is close to the bottom wall of the bottle body 1, thereby reducing the residual flushing liquid in the bottle during use.

[0090] The currently commonly used straight-through catheter not only is easy to leave solution residues, but also cannot prevent backflow or reverse flow, and is easy to cause the solution in the bottle to be contaminated in the cleaning process. When flushing, if the flushing head does not leave the nostril in time when the bottle rebounds, it may cause backflow and contaminate the pipeline and the solution in the bottle.
