Description

Technical Field

[0001] This utility model belongs to the field of medical device technology, specifically relating to a portable electric nasal irrigator. Background Technology

[0002] Nasal irrigators are used clinically as nasal irrigation devices. Generally, an electric nasal irrigator consists of a water tank, a nasal tip, and a main unit with a drive mechanism. However, whether in a home or a hospital, electric nasal irrigators face the issue of multiple users, especially in home settings where the device needs to be portable and compact while also avoiding the risk of cross-contamination from multiple users.

[0003] Chinese utility model patent CN 217828377U discloses a nasal cavity care device, which includes a housing and a cleaning mechanism and a suction mechanism installed on the housing. The cleaning mechanism includes a cleaning nozzle, a clean water pump, and a clean water tank. A first clean water pipe is connected between the clean water tank and the clean water pump, and a second clean water pipe is connected between the clean water pump and the cleaning nozzle. Liquid in the clean water tank is pumped by the clean water pump to the cleaning nozzle and sprayed out. The suction mechanism includes a suction head, a suction pump, and a wastewater tank. A first wastewater pipe is connected between the wastewater tank and the suction pump, and a second wastewater pipe is connected between the suction pump and the suction head. Wastewater suctioned by the suction head is pumped to the wastewater tank by the suction pump. The nasal cavity care device also includes a connecting pipe connecting the clean water tank and the wastewater tank.

[0004] However, its shortcomings are as follows: In the above technical solution, clean water flows from the clean water tank through the first clean water pipe to the clean water pump, and then from the clean water pump through the second clean water pipe to the cleaning nozzle. Wastewater flows from the suction head through the second wastewater pipe to the suction pump, and then from the suction pump through the first wastewater pipe to the wastewater tank. Thus, the pipes, clean water pump, and suction pump inside the main unit are all passed through by the cleaning liquid. A particularly significant problem is that the suction pump, the first wastewater pipe, and the second wastewater pipe inside the main unit are all contaminated by the wastewater flowing through them. It is difficult to thoroughly clean and disinfect the suction pump and wastewater pipes inside the main unit after use, making cross-infection unavoidable. Secondly, the "clean water" flowing through the clean water pump and its connected clean water pipes is often a nasal spray used to treat rhinitis. Since each person uses different nasal sprays, residual nasal spray in the pump and its connected pipes can affect the nasal spray used by a second patient. In conclusion, this nasal care device is not suitable for use by multiple people in hospital outpatient departments. Summary of the Invention

[0005] The purpose of this invention is to provide a portable electric nasal irrigator. Compared with existing technologies, the pipes and suction pump inside this nasal irrigator do not have waste liquid flowing through them, and there is no residual wastewater in the pipes and suction pump. After use, there is no need to clean and disinfect the suction pump, thus avoiding cross-infection. The used nasal irrigator components are detachable and replaceable, making it suitable for multiple users in hospital outpatient departments.

[0006] In order to achieve the above-mentioned objectives, the present invention adopts the following technical solution; A portable electric nasal irrigator includes a nasal irrigation component, a main unit, a tubing, and a water tank. The nasal irrigation component includes a first nasal plug and a second nasal plug. Furthermore, the nasal irrigation component is a detachable part: when the nasal irrigator is in use, the nasal irrigation component is installed in the main unit and integrated with the main unit; when cleaning or replacing, the nasal irrigation component is detached from the main unit and separated from the main unit. The nasal irrigation assembly also includes a fluid path assembly; The fluid circuit assembly comprises two non-interconnected fluid circuits, namely fluid circuit one and fluid circuit two. The first liquid path is connected to the first nasal plug, and the second liquid path is connected to the second nasal plug. Either liquid path can be connected to the clean water compartment of the water tank by inserting a tube, while the other liquid path is directly connected to the waste liquid compartment of the water tank.

[0007] The main unit includes a positive pressure pump and a negative pressure pump. One end of the first air pipe is connected to the air outlet of the positive pressure pump, and the other end of the first air pipe is connected to the first air outlet of the main unit. One end of the second air pipe is connected to the air inlet of the negative pressure pump, and the other end of the second air pipe is connected to the second air outlet of the main unit.

[0008] The first air outlet of the main unit is connected to the clean water tank of the water tank, and the second air outlet of the main unit is connected to the wastewater tank.

[0009] The nasal irrigation assembly also includes a connector for connecting the nasal irrigation tip and the fluid path assembly.

[0010] The main unit also contains a control circuit.

[0011] Beneficial Effects: This portable electric nasal irrigator, as proposed in this invention, features a main unit where the pipes and suction pump are free of waste liquid from cleaning, leaving no residual wastewater. This eliminates the need for post-use cleaning and disinfection of the suction pump, preventing cross-infection. Furthermore, the positive pressure pump and its connected pipes do not carry any medication intended for treating rhinitis, leaving no residual medication and thus having no impact on the medication used by a second patient. In summary, this nasal irrigator is suitable for multiple-use in hospital outpatient departments. The nasal irrigator components, which are relatively difficult to clean and disinfect, have a simple structure, are easy to clean, and can withstand moist heat disinfection. In practical operation, used nasal irrigator components can be replaced without any tools. Due to their simple structure and low cost, the nasal irrigator components can be used as disposable consumables. When a second person uses it, simply remove the used components and water tank, reinstall the new components and water tank on the original main unit, and a clean nasal irrigator is ready. This achieves the invention's objective of multi-user use. Attached Figure Description

Detailed Implementation

[0017] The embodiments of this utility model patent will now be described in detail with reference to the accompanying drawings.

[0018] A portable electric nasal irrigator includes a nasal irrigation component 1, a main unit 2, a catheter 3, and a water tank 4. The nasal irrigation component 1 includes a first nasal plug 11 and a second nasal plug 12. Furthermore, the nasal irrigation component 1 is a detachable part: when the nasal irrigator is in use, the nasal irrigation component 1 is installed in the main unit 2 and integrated with the main unit 2; when cleaning or replacing, the nasal irrigation component 1 is detached from the main unit 2 and separated from the main unit 2. The nasal irrigation assembly 1 further includes a liquid path assembly 14; The liquid circuit assembly 14 comprises two non-interconnected liquid circuits, namely liquid circuit one 141 and liquid circuit two 142. The first liquid path 141 is connected to the first nasal plug 11, and the second liquid path 142 is connected to the second nasal plug 12. Either liquid path can be connected to the clean water chamber 41 of the water tank 4 after the tube 3 is inserted, and the other liquid path is directly connected to the waste liquid chamber 42 of the water tank.

[0019] The main unit 2 includes a positive pressure pump 21 and a negative pressure pump 22. One end of the first air pipe 23 is connected to the air outlet of the positive pressure pump 21, and the other end of the first air pipe 23 is connected to the first air outlet 25 of the main unit 2. One end of the second air pipe 24 is connected to the air inlet of the negative pressure pump 22, and the other end of the second air pipe 24 is connected to the second air outlet 26 of the main unit 2.

[0020] The first air outlet 25 of the main unit is connected to the clean water chamber 41 of the water tank 4, and the second air outlet 26 of the main unit is connected to the wastewater chamber 42.

[0021] The nasal irrigation assembly 1 also includes a connector 13 for connecting the nasal irrigation head and the liquid path assembly 14.

[0022] The main unit 2 also contains a control circuit.

[0023] Combined with appendix Figure 4 When the nasal irrigator is in use, the nasal irrigation component 1 is installed in the main unit 2 and integrated with the main unit 2. The positive pressure pump 21 is activated, and positive air pressure is input into the clean water tank 41 through the first air pipe 23 and the first air outlet 25. The cleaning solution in the clean water tank 41 is under positive pressure and flows from the conduit 3 and the liquid path 141 into the nasal plug 11, passes through the nasal cavity, and flows out from the plug 12. At the same time, the negative pressure pump 22 is activated, and negative air pressure is input into the waste water tank 42 through the second air pipe 24 and the second air outlet 26. The inner cavity of the waste water tank 42 is under negative pressure, which pushes the liquid path 142 connected to the upper end of the waste water tank 42 to draw in the waste liquid flowing out of the plug 12 and accelerates its flow into the waste water tank 42.
