Description

Technical Field

[0001] The present invention relates to the field of nasal washers, and in particular to a full-flow-channel electric nasal wash system device. Background Art

[0002] Electric nasal irrigators are used as nasal irrigation devices. In a large number of clinical applications, doctors often provide targeted treatment based on the specific conditions of the patient and the disease, adding drugs of different dosages or different composition combinations to the cleaning solution. Therefore, clinically, it is required that no drugs remain in the device, otherwise it will lead to incorrect medication and improper treatment. However, most existing nasal irrigators are personal products and can only meet the use scenarios of a single patient. A single traditional nasal irrigator system cannot adapt to the use scenarios of multiple rhinitis patients in the hospital, and it fails to achieve the situation where one device can be reused by multiple people.

[0003] Secondly, in the prior art nasal irrigation machines that use a positive and negative pressure pump structure, the positive pressure increases the air pressure in the liquid supply container. Under the strong air pressure, the liquid supply solution overcomes gravity and reaches the nostrils through the cleaning component. The negative pressure connects the cleaning component and, under the guidance of the negative pressure, the liquid supply solution flows through the nostrils to the waste liquid container. However, under the positive pressure, the solution in the liquid supply container overcomes the gravitational potential energy and flows from the liquid supply container with low potential energy to the nostrils. On the other hand, on the waste liquid container side, the solution flows from the nostrils with high potential energy to the waste liquid container with low potential energy under the guidance of the negative pressure. This increases the pressure of the liquid supply solution, exerts a greater impact on the nasal cavity, and can easily cause discomfort to the user. There is also a risk of backflow of the cleaning liquid or waste liquid damaging the equipment.

[0004] Again, in the prior art, the device for preventing bacteria and viruses in the waste liquid in the waste liquid bottle from entering the host and the nasal cavity is not perfect enough.

[0005] In summary, the existing technology has not yet been able to truly design a rhinitis medical device that can effectively prevent cross contamination and is suitable for multiple reuse in hospitals. Summary of the Invention

[0006] The present invention provides a full-channel electric nasal irrigation system. This device not only features replaceable components through the full channel, thus preventing drug residue, but also effectively addresses the issues of excessive water flow velocity and flow rate impacting the patient's nasal cavity, the risk of liquid backflow, and prevents bacteria and viruses from waste liquid bottles from entering the main unit and nasal cavity. The cost of consumables required for each treatment is very low, significantly reducing the financial burden on patients. This makes it a rhinitis medical device that effectively prevents cross contamination and is suitable for multiple-person reuse in hospitals.

[0007] In order to achieve the above object of the invention, the present invention adopts the following technical solutions: A full-channel electric nasal irrigation system device includes a main unit, which is equipped with a positive pressure pump and a negative pressure pump; further, the system device also includes a disposable component; the disposable component includes: a nasal plug head assembly consisting of a first nasal plug head and a second nasal plug head, a cleaning liquid bottle and a waste liquid bottle, a positive pressure tube, a liquid inlet tube, a waste liquid tube, a negative pressure tube first, and a negative pressure tube second; a. The inner diameter of the waste pipe is larger than the inner diameter of the inlet pipe; b in the negative pressure pump and the waste bottle communicating pipe sequentially by the pipe two, the negative pressure pipe two, a negative pressure pipe connected to form; in the negative pressure pipe two and a negative pressure pipe provided between the airlock chamber, the airlock chamber is transparent visualization; c. An air pressure sensor is installed in the output pipe of the negative pressure pump, which feeds back the negative pressure to the control circuit of the negative pressure pump to ensure that the negative pressure value remains constant; d. The pipeline connecting the positive pressure pump and the cleaning liquid bottle is formed by connecting pipeline 1 and the positive pressure pipe in sequence; an air valve is provided between pipeline 1 and the positive pressure pipe; When cleaning the nasal cavity, pipes 1 and 2 of the main unit are respectively connected to one end of the air valve of the disposable component and negative pressure tube 2; after cleaning the nasal cavity, pipes 1 and 2 of the main unit are respectively disconnected from one end of the air valve of the disposable component and negative pressure tube 2, and the disposable component is removed from the main unit.

[0008] A T-shaped valve body is arranged in the air valve.

[0009] The waste liquid bottle consists of a bottle body and a bottle cap, and a filter element is arranged in the through hole at the lower end of the waste liquid pipe on the bottle cap.

[0010] An operation screen and a control circuit are also provided in the host machine. Beneficial effects

[0011] Compared with the prior art, the beneficial effects of the full-channel electric nasal irrigation system device of the present invention are: 1. The present invention proposes a structural design in which the diameter of the waste liquid pipe is larger than that of the liquid inlet pipe. The inner diameter of the water outlet is larger than that of the water inlet. Given the same flow rate, the flow rate at the outlet will be lower than that at the inlet. According to the Bernoulli equation in fluid mechanics, if friction losses are ignored, reducing the diameter of the water inlet pipe will increase the fluid velocity and decrease the pressure, meaning that the pressure at the inlet will be lower than that at the outlet. By optimizing the flow channel diameter, the problem of high water pressure on the nasal cavity is resolved.

[0012] 2. An airlock chamber is installed in the pipeline connecting the negative pressure pump and the waste liquid bottle. The airlock isolation structure of this airlock chamber effectively solves the problem of gas backflow. Through the interlocking mechanism of the door and air pressure control, it ensures that when air flows between environments with different cleanliness levels or air pressures, the waste liquid in the waste liquid bottle and the generated harmful substances will not spread through the pipeline to contaminate the negative pressure pump. The airlock chamber is transparent and visible, and the operator can immediately see whether there is waste liquid flowing into the airlock cavity, so that the operator can deal with it in time.

[0013] 3. An air valve is set between the positive pressure pump and the cleaning fluid bottle, and a T-shaped valve body is installed inside the air valve. The structural design of the T-shaped valve body enables it to flexibly control the flow direction and flow rate of the cleaning fluid.

[0014] 4. A filter core is provided in the pipe between the nasal plug head and the waste liquid bottle to prevent bacteria and viruses in the waste liquid bottle from entering the nasal plug head through the waste liquid pipe, thereby protecting the cleanliness of the patient's nasal cavity.

[0015] 5. When the nasal irrigation system is used on multiple patients in a hospital, the used disposable component YC can be simply removed from the main unit and replaced with a new one. The more expensive main unit does not need to be replaced, thus minimizing the cost of consumables required for each treatment, significantly reducing the financial burden on patients.

[0016] In summary, through the above design, the nasal wash system device becomes a rhinitis medical device that effectively prevents cross contamination and is suitable for multiple reuse in the hospital. BRIEF DESCRIPTION OF THE DRAWINGS
