Description

Technical Field

[0001] This utility model belongs to the field of nasal irrigation technology, and in particular relates to an adjustable negative pressure nasal irrigator. Background Technology

[0002] Nasal irrigation is suitable for patients with chronic rhinitis, sinusitis, and chronic inflammation of the nasopharynx. It can clear secretions from the nasal cavity, relieve nasal congestion, and has an adjunctive therapeutic effect. A nasal irrigator is required during nasal irrigation.

[0003] Chinese utility model patent CN222566268U discloses an airbag-type nasal irrigator. This device uses a liquid-filled airbag to hold the cleaning fluid, which has strong rebound force, facilitating squeezing and ensuring continuous rinsing. Furthermore, the airbag, rinsing head, connecting bend, and rinsing tube are assembled together for easy disassembly and cleaning, ensuring the cleanliness of each component. A one-way outlet valve embedded in the rinsing head prevents backflow of the cleaning fluid in the tubing and avoids contamination of the cleaning fluid in the airbag. Simultaneously, a one-way air inlet valve maintains the pressure balance inside the airbag, facilitating the outflow of the cleaning fluid. The overall structure is simple and the manufacturing cost is low.

[0004] A search revealed that existing solutions, including the aforementioned comparative documents, are not convenient for easy recovery of nasal irrigation fluid. The fluid easily adheres to the skin or stains clothing, making cleaning difficult. Furthermore, the cleaning fluid is prone to leakage through gaps between the tube and the nasal cavity, affecting irrigation efficiency. Therefore, there is an urgent need to improve existing nasal irrigators and provide an adjustable negative pressure nasal irrigator. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by providing an adjustable negative pressure nasal irrigator that is reasonably designed, simple in structure, convenient for wastewater recycling, and has high rinsing efficiency, thereby solving the problems existing in the prior art.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] An adjustable negative pressure nasal irrigator includes an installation head, a charging port, a battery, a first shaped curved tube, a second shaped curved tube, a squeezeable inflatable ball, a negative pressure pump, and a suction pump. A liquid storage assembly is detachably installed at the bottom of the installation head. A charging port is located on the right outer wall of the installation head. The negative pressure pump, suction pump, and battery are fixedly installed inside the installation head from left to right. The first and second shaped curved tubes are installed at the upper end of the installation head. The bottom end of the first shaped curved tube is fixedly connected to the input end of the negative pressure pump, and the bottom end of the second shaped curved tube is fixedly connected to the output end of the suction pump. Connector assemblies are fixedly installed at the top ends of the first and second shaped curved tubes. A squeezeable inflatable ball is located between the first and second shaped curved tubes. A discharge pipe is fixed to the output end of the negative pressure pump, and a suction pipe is fixed to the input end of the suction pump.

[0008] In a preferred embodiment, the liquid storage assembly includes an outer cylinder, a display panel, an inner cylinder, and a sealing gasket. The outer cylinder is threaded to the bottom end of the mounting head. The display panel, made of transparent plexiglass, is embedded and fixed on the left front outer wall of the outer cylinder. The inner cylinder is fixedly installed at the center of the inner side of the outer cylinder. Sealing gaskets, made of elastic rubber, are bonded to the top surfaces of both the outer and inner cylinders.

[0009] In a preferred embodiment, an annular sewage chamber is formed between the outer cylinder and the inner cylinder, and a clean water chamber is provided inside the inner cylinder.

[0010] In a preferred embodiment, the bottom end of the discharge pipe extends into the sewage chamber, and the bottom end of the pumping pipe extends to the bottom of the clean water chamber.

[0011] In a preferred embodiment, the first shaped curved pipe is a sewage recovery pipe, and the second shaped curved pipe is a clean water flushing pipe.

[0012] In a preferred embodiment, the connector assembly includes a nasal insert, an air bladder, and a thin air tube. The nasal insert has an inverted funnel-shaped structure. The two nasal inserts are respectively fixedly connected to the top of the first and second shaped curved tubes. An air bladder is adhesively fitted to the outer side of the top of the nasal insert. The bottom of the air bladder is connected to the thin air tube. The other end of the thin air tube is fixedly connected to the air delivery end of the hand-squeezed inflatable ball.

[0013] In a preferred embodiment, the charging port, the negative pressure pump, and the suction pump are all electrically connected to the battery.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0015] In the solution of this utility model:

[0016] This device is equipped with a second fixed-shape curved tube for conveying clean water and a first fixed-shape curved tube for recycling wastewater. Both the first and second fixed-shape curved tubes are hollow tubes with common shapes that can be adjusted and shaped at will, which makes it easy to insert the nasal tube into the nasal cavity. Furthermore, a negative pressure pump can be used to draw the wastewater into the wastewater cavity. During the nasal irrigation process, the negative pressure is used to draw the wastewater into the wastewater cavity, which facilitates unified treatment after rinsing and avoids the wastewater from adhering to the skin or staining clothing.

[0017] Insert two nasal tubes and two airbags into each nostril. Then, by squeezing the inflatable tube, the two thin air tubes can be used to inflate the two airbags, which will expand the airbags in the nasal cavity and seal the nasal cavity. This allows for quick adjustment according to the different nasal cavity sizes of different patients, and can prevent the cleaning solution from leaking through the gaps between the tubes and the nasal cavity during nasal irrigation, resulting in better nasal irrigation. The squeezing inflatable tube is a commercially available tool, and it also has a manual pressure relief valve at the bottom, which makes it easy to release the inflation of the airbags after irrigation.

[0025] The embodiments described below are merely some embodiments of the present invention and do not represent all embodiments consistent with the present invention. Exemplary embodiments will now be described with reference to the accompanying drawings:

[0026] like Figure 1-4 As shown, this utility model of an adjustable negative pressure nasal irrigator includes an installation head 1, a charging port 3, a battery 4, a first shaped bending tube 5, a second shaped bending tube 6, a hand-operated inflatable ball 8, a negative pressure pump 9, and a suction pump 11.

The negative pressure pump 9, the suction pump 11, and the battery 4 are fixedly installed inside the installation head 1 from left to right. A first shaped bending tube 5, a second shaped bending tube 6, a hand-operated inflatable ball 8, a negative pressure pump 9, and a suction pump 11 are installed at the top of the installation head 1. The first shaped bend tube 5 and the second shaped bend tube 6 are fixedly connected. The bottom end of the first shaped bend tube 5 is fixedly connected to the input end of the negative pressure pump 9, and the bottom end of the second shaped bend tube 6 is fixedly connected to the output end of the suction pump 11. The top ends of the first shaped bend tube 5 and the second shaped bend tube 6 are fixedly installed with a connector assembly 7. A hand-squeezable inflation ball 8 is provided between the first shaped bend tube 5 and the second shaped bend tube 6. The output end of the negative pressure pump 9 is fixed with a discharge pipe 10, and the input end of the suction pump 11 is fixed with a water suction pipe 12.

[0027] Based on the above structure, the liquid storage assembly 2 includes an outer cylinder 21, a display panel 22, an inner cylinder 23, and a sealing gasket 24. The outer cylinder 21 is threaded to the bottom end of the mounting head 1. The display panel 22 is embedded and fixed on the left front outer wall of the outer cylinder 21. The display panel 22 is made of transparent organic glass. The inner cylinder 23 is fixedly installed at the center of the inner side of the outer cylinder 21. The sealing gasket 24 is bonded to the top surface of both the outer cylinder 21 and the inner cylinder 23. The sealing gasket 24 is made of elastic rubber.

[0028] In this embodiment, sealing gaskets 24 are bonded to the top of both the outer cylinder 21 and the inner cylinder 23 to facilitate the sealing between the outer cylinder 21 and the inner cylinder 23 and the mounting head 1.

[0029] Based on the above structure, an annular sewage chamber 25 is formed between the outer cylinder 21 and the inner cylinder 23, and a clean water chamber 26 is opened inside the inner cylinder 23.

[0030] In this embodiment, the wastewater chamber 25 facilitates the recycling of rinsing wastewater, preventing the wastewater from adhering to the skin or staining clothing.

[0031] Based on the above structure, the bottom end of the discharge pipe 10 extends into the sewage chamber 25, and the bottom end of the pumping pipe 12 extends to the bottom of the clear water chamber 26.

[0032] In this embodiment, the water in the water chamber 26 is easily drawn out and delivered to the nasal cavity through the water suction pipe 12, which facilitates nasal irrigation.

[0033] Based on the above structure, the first shaped bend pipe 5 is a sewage recovery pipe, and the second shaped bend pipe 6 is a clean water flushing pipe.

[0034] In this embodiment, the first shaped bending tube 5 and the second shaped bending tube 6 are both hollow tubes with shapes that are commonly available on the market and can be adjusted and shaped at will, so as to facilitate the arbitrary adjustment of their shapes and spacing to meet actual use requirements.

[0035] Based on the above structure, the connector assembly 7 includes a nasal insert 71, an air bladder 72, and a thin air tube 73. The nasal insert 71 has an inverted funnel-shaped structure. The two nasal inserts 71 are fixedly connected to the top of the first shaped curved tube 5 and the second shaped curved tube 6, respectively. The air bladder 72 is glued to the outer side of the top of the nasal insert 71. The bottom of the air bladder 72 is connected to the thin air tube 73. The other end of the thin air tube 73 is fixedly connected to the air supply end of the hand-squeezed inflatable ball 8.

[0036] In this embodiment, by squeezing the inflatable ball 8, the two thin air tubes 73 can be inflated into two air bladders 72, which can seal the nasal cavity and facilitate quick adjustment according to the different nasal cavity sizes of different patients. This can prevent the cleaning solution from leaking through the gap between the tube and the nasal cavity during nasal irrigation.

[0037] Based on the above structure, the charging port 3, the negative pressure pump 9, and the suction pump 11 are all electrically connected to the storage battery 4.

[0038] In this embodiment, the storage battery 4 can provide power for the operation of the negative pressure pump 9 and the suction pump 11. The charging port 3 facilitates the replenishment of power to the storage battery 4. The specific circuit layout and charging method are all mature existing technologies.

[0039] The working principle of this utility model is as follows:

[0040] In use, first add the rinsing solution to the clean water chamber 26, then thread the outer cylinder 21 to the mounting head 1. The rubber sealing gasket 24 facilitates the sealing between the outer cylinder 21 and the inner cylinder 23 and the mounting head 1, which can prevent interference between the dirty water chamber 25 and the clean water chamber 26. Then, insert the two nasal inserts 71 and the two air bags 72 into the two nostrils respectively, and insert the nasal insert 71 at the top of the second shaped curved tube 6 into the nasal cavity to be rinsed. Then, by squeezing the inflation ball 8, the two thin air tubes 73 can be inflated into the two air bags 72 respectively, which facilitates the sealing of the nasal cavity and allows for quick adjustment according to the different nasal cavity sizes of different patients. This can prevent the rinsing solution from leaking through the gap between the tube and the nasal cavity during the nasal rinsing process, resulting in a better nasal rinsing effect.

[0041] Start the suction pump 11, and draw out the rinsing fluid from the clean water chamber 26 through the water pipe 12 and spray it into the nasal cavity to begin rinsing. At the same time, turn on the negative pressure pump 9 to draw the sewage chamber 25 into negative pressure. During the nasal cavity rinsing process, the negative pressure facilitates the suction of sewage into the sewage chamber 25 through the first shaped curved tube 5 and the discharge tube 10, which is convenient for unified sewage treatment and avoids the sewage from adhering to the skin or staining clothes. The first shaped curved tube 5 and the second shaped curved tube 6 are both hollow tubes with common shapes that can be adjusted and shaped at will, which makes it easy to adjust the shape and spacing of the two to meet the actual use needs.

[0042] It should be noted that the specific structure, operating principle and circuit layout of the charging port 3, the battery 4, the negative pressure pump 9 and the suction pump 11 are all mature existing technologies and are not the key improvement directions of this case, so they will not be described in detail. The hand-squeezed inflatable ball 8 is also a widely used existing tool, and its bottom is equipped with a manual pressure relief valve to facilitate the release of the inflated state of the airbag 72 after rinsing.

[0043] The above are merely preferred embodiments of this utility model and are not intended to limit the scope of protection of this utility model. Any equivalent changes, modifications, substitutions, and variations made by those skilled in the art based on the concept of this utility model and on the basis of existing technology through logical analysis, reasoning, or limited experiments shall be within the scope of protection defined by the claims.
