Description

Technical Field

[0001] The utility model relates to the technical field of medical devices, in particular to a portable handheld negative pressure nasal washer. Background Art

[0002] The principle of a nasal rinse is to wash the nose with salt water. The anti-inflammatory and antibacterial properties of salt water clear the nasal cavity, especially the sinuses, of allergens, bacteria, viruses, and mucus that accumulate. This creates a clean and refreshing environment for the nasal cavity, restores the function of the nasal cilia, and accelerates recovery. For common allergic rhinitis, frequent nasal irrigation can increase the nasal cavity's tolerance to allergens and gradually eliminate the nasal allergic reaction to them.

[0003] As a tool for cleaning the nasal cavity, a nasal irrigator usually uses a certain amount of pressure (either suction, such as a Dianbang airbag nasal irrigator, gravity, such as a simple bottle-type nasal irrigator, or mechanical pressure, such as an electric nasal irrigator) to deliver normal saline into the nostrils. The saline flows through the nasal vestibule (the part exposed outside the head), sinuses, and nasal passages, bypassing the nasopharynx, and is discharged from one nostril or the mouth. However, most nasal irrigators currently have a complex structure and are large in size, making them inconvenient to carry. In addition, wastewater easily enters the vacuum pump, affecting its service life, resulting in a poor user experience for common nasal irrigators. To this end, we have invented a new portable, handheld negative pressure nasal irrigator that solves the above technical problems. Utility Model Content

[0024] like Figure 1 and Figure 2The figure shows the structure of the portable handheld negative pressure nasal irrigator of the present invention. The portable handheld negative pressure nasal irrigator includes a small water tank cover 1, a sealing ring 2, a filter 3, a large water tank cover 4, a sealing ring 5, an air outlet check valve 6, a fresh water tank 7, a body 8, left and right nasal interface sleeves 9, a left nasal interface 10, a right nasal interface 11, an automatic check valve 12, left and right nasal cover 13, a left nasal tube sealing ring 14, a right nasal tube sealing ring 15, left and right nasal cover panel assemblies 16, a sealing ring 17, a sealing ring 18, a vacuum pump 19, a lithium battery 20, a battery compartment 21, a USB charging cable 22, a switch button 23, a movement assembly 24, a self-made air inlet valve 25, a rubber tube 26, a sealing ring 27, a sealing ring 28, a sealing ring 29, a middle adapter 30, a waste water tank 31, a USB seat cover 32, and a USB charging seat 33.

[0025] After the filter screen 3 is installed under the small water tank cover 1 through the sealing ring 2, it is installed on the large water tank cover 4 to filter the liquid entering the clean water tank 7. The large water tank cover 4 is located above the clean water tank 7 and seals the clean water tank 7 with the sealing ring 5. The clean water tank 7 is located inside the fuselage 8 and is designed to be integrated with the fuselage 8. The front ends of the left and right nasal interfaces are the left and right nasal interfaces 10 and 11, which can be inserted into the left and right noses, and the rear ends are connected to the clean water tank 7. The left and right nasal interfaces are equipped with waterproof silicone rings. The left nasal interface is 17, and the right nasal interface is 18, which directly plugs into the fuselage. The fuselage and the left and right nasal interfaces are cylindrical plug-in structures, so the left and right nasal interfaces can rotate 360 degrees simultaneously. Specifically, the automatic one-way valve 12, the left and right nasal cover 13, the left nasal tube sealing ring 14, the right nasal tube sealing ring 15, the left and right nasal cover panel assemblies 16, the sealing ring 17, and the sealing ring 18 are all rotatable and form a "one-piece" structure.

[0026] The left nose interface 10 and the right nose interface 11 are made of rubber material and are mounted on the left and right nose covers 13. The left and right nose covers 13 are connected to the left and right nose panel assemblies 16 through the left nasal tube sealing ring 14 and the right nasal tube sealing ring 15. The left and right nose panel assemblies 16 are inserted into the fuselage 8 through the sealing rings 17 and 18.

[0027] The left and right nasal interface sleeves 9 are sleeved on the left nasal interface 10 and the left nasal interface 11 to keep the interfaces clean and sanitary when not in use.

[0028] The automatic one-way valve 12 is located in the left and right nose covers 13 and the left nose interface 10 to prevent water from flowing out of the left nose interface 10 due to gravity after the clean water tank 7 is full.

[0029] The air outlet one-way valve 6 is located at the air outlet in the clean water tank 7 and is connected to the air outlet of the vacuum pump 19. Its function is to prevent the water in the clean water tank 7 from entering the vacuum pump 19 when the clean water tank 7 is filled with water and the machine is not turned on.

[0030] The middle adapter seat 30 is located below the fuselage 8 , the waste water tank 31 is located on the middle adapter seat 30 , and the bottom of the fuselage 8 is ultrasonically connected to the middle adapter seat 30 and is also connected to the waste water tank 31 in a card-type sealing manner.

[0031] One end of the rubber tube 26 is connected to the air outlet of the vacuum pump, and the other end is connected to the clean water tank 7 through the sealing ring 27 and the sealing ring 28.

[0032] The middle adapter seat 30 is connected to the bottom of the fuselage 8 through a sealing ring 29.

[0033] like Figure 3 As shown, the self-made air inlet valve 25 is located in the funnel of the middle adapter 30. When the waste water tank 31 is full, the self-made one-way valve 25 will block the air inlet of the vacuum pump 19 with the buoyancy of the water and the suction force of the vacuum pump 19, preventing the waste water from entering the vacuum pump 19.

[0034] The lithium battery 20 is located in the battery compartment 21, the switch button 23 is connected to the battery compartment 21, and the battery compartment 21 is connected to the vacuum pump 19. When the switch button 23 is pressed, the lithium battery 20 supplies power to the vacuum pump 19, causing the vacuum pump 19 to start working.

[0035] The movement assembly 24 is connected to the battery compartment and the switch button 23. The movement assembly controls the speed and gear of the vacuum pump under the control of the switch button 23. The switch button 23 can be pressed once to turn on the pump, twice to shift to first gear, twice to second gear, three times to third gear, and a fourth time to shut down the pump. These switching functions are implemented by the movement assembly 24.

[0036] The USB charging seat 33 is connected to the battery compartment 21 , and an external power source is connected to the USB charging seat 33 via a USB charging cable 22 to charge the lithium battery 20 in the battery compartment 21 .

[0037] The USB seat cover 32 covers the USB charging seat 33 to prevent dust.

[0038] When using this portable handheld negative pressure nasal rinser, the left nasal port is connected to the clean water tank, and the right nasal port is connected to the waste water tank below through the internal pipe of the machine body. The clean water tank and the waste water tank are connected by a vacuum pump. The suction end of the vacuum pump is at the top of the waste water tank, and the air outlet is at the top of the clean water tank. When the vacuum pump is turned on, the clean water tank has positive pressure, and the waste water tank has negative pressure, which is connected to the human nasal cavity to form a closed "pipeline".

[0039] The lower end of the vacuum pump is connected to the air inlet, which has a custom one-way valve located in the wastewater tank. When the vacuum pump starts operating, the clean water tank is under positive pressure, while the wastewater tank is under negative pressure. Under the action of positive pressure, the water in the clean water tank enters the left nasal port, through the left nose sleeve inserted into the left nose, and into the nasal cavity. After cleaning the nasal cavity, the water passes through the right nose sleeve inserted into the right nose, enters the right nasal port, and then enters the wastewater tank through the internal pipe of the fuselage.

[0040] When the wastewater tank is full, the self-made one-way valve at the air inlet floats on the water, increasing the suction of the vacuum pump to block the vacuum pump's suction port and prevent water from entering the vacuum pump. When the wastewater tank is empty and there is no suction, the self-made one-way valve at the air inlet falls under its own gravity and falls to the bottom of the funnel at the middle adapter.

[0041] During assembly, first install the homemade one-way valve in the funnel in the middle adapter. When the wastewater tank is full, the homemade one-way valve will block the vacuum pump's suction port due to the buoyancy of the water and the suction of the vacuum pump, preventing wastewater from entering the vacuum pump.

[0042] Automatic one-way valves are designed at the water outlets of the left and right nose covers. When the clean water tank is full, water will not flow out of the left nose port due to gravity. The water in the clean water tank will only be pushed open when the vacuum pump is turned on. The vacuum pump suction port draws air from the waste water tank, and the air flows out of the air outlet, forming pressure in the clean water tank. At this time, the automatic one-way valve will be pushed open.

[0043] Compared with the prior art, the present invention has the following technical features:

[0044] 1. A self-made valve is designed at the suction port of the wastewater tank to prevent wastewater from entering the vacuum pump when it is full.

[0045] 2. A one-way valve is designed at the outlet of the clean water tank to prevent clean water from being added before starting the machine and entering the vacuum pump after the clean water is full.

[0046] 3. The left water outlet of the left and right nose covers is designed with an automatic one-way valve to prevent adding clean water before starting the machine. After the clean water is full, the clean water will flow out from the left water outlet due to gravity.

[0047] Finally, it should be noted that the above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art may still modify the technical solutions described in the aforementioned embodiments or substitute equivalents for some of the technical features therein. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.

[0048] Except for the technical features described in the specification, all other technical features are known technologies to those skilled in the art.
