Description

Technical Field

[0001] This utility model relates to the field of nasal irrigators, specifically to a full-flow electric nasal irrigator system. Background Technology

[0002] As a nasal irrigation device, the electric nasal irrigator is widely used in clinical practice. Doctors often add different dosages or combinations of medications to the rinsing solution to provide targeted treatment based on the specific condition of the patient and their disease. Therefore, it is crucial in clinical practice that no medication residue remains in the device; otherwise, incorrect medication may occur, leading to inappropriate treatment. However, most existing nasal irrigators are personal items, only suitable for a single patient. A single traditional nasal irrigation system cannot meet the needs of multiple rhinitis patients in a hospital setting, failing to achieve the goal of reusing a single device for multiple patients.

[0003] Secondly, in existing nasal irrigators using positive and negative pressure pumps, the positive pressure increases the air pressure in the supply container. Under this strong pressure, the supply solution overcomes gravity and reaches the nostrils through the cleaning assembly. The negative pressure connects to the cleaning assembly, guiding the supply solution through the nostrils to the waste container. However, while the solution in the supply container overcomes gravitational potential energy under positive pressure and flows from the lower potential energy supply container to the nostrils, the solution in the waste container flows from the higher potential energy nostrils to the lower potential energy waste container under negative pressure. This results in increased pressure of the supply solution, creating a greater impact on the nasal cavity and potentially causing discomfort to the user. Furthermore, there is a risk of backflow of cleaning or waste liquid damaging the equipment.

[0004] Furthermore, the existing technology is not yet perfect in preventing bacteria and viruses in the waste liquid from entering the main unit and nasal cavity.

[0005] In conclusion, current technology has not yet been able to design a rhinitis medical device that effectively prevents cross-contamination and is suitable for reuse by multiple people in a hospital. Summary of the Invention

[0006] This invention provides a fully-flow-channel electric nasal irrigation system. This nasal irrigator not only features replaceable components throughout the entire flow channel, avoiding drug residue, but also effectively solves the problems of excessive water flow rate and volume impacting the patient's nasal cavity, the risk of backflow, and preventing bacteria and viruses from the waste bottle from entering the main unit and nasal cavity. The consumable costs for each patient are very low, significantly reducing the economic burden on patients. This makes it an effective rhinitis medical device that prevents cross-contamination and is suitable for reuse by multiple patients in hospitals.

[0007] To achieve the above-mentioned objectives, this utility model adopts the following technical solution: A full-flow electric nasal irrigation system includes a main unit, which is equipped with a positive pressure pump and a negative pressure pump. Furthermore, the system also includes disposable components. The disposable components include: a nasal plug assembly consisting of a first nasal plug and a second nasal plug, a cleaning solution bottle and a waste solution bottle, a positive pressure tube, an inlet tube, a waste solution tube, a first negative pressure tube, and a second negative pressure tube. a. The inner diameter of the waste liquid pipe is larger than the inner diameter of the inlet pipe; b. The connecting pipe between the negative pressure pump and the waste liquid bottle is formed by connecting pipe two, negative pressure pipe two, and negative pressure pipe one in sequence; an airlock is provided between negative pressure pipe two and negative pressure pipe one, and the airlock is transparent and visible; c. A pressure sensor is installed in the output pipe of the negative pressure pump to provide feedback to the control circuit of the negative pressure pump based on the magnitude of the negative pressure, so as to ensure that the negative pressure value remains constant. d. The pipeline connecting the positive pressure pump and the cleaning fluid bottle consists of a pipeline 1 and a positive pressure pipe connected sequentially; an air valve is installed between the pipeline 1 and the positive pressure pipe; During nasal cavity cleaning, pipes one and two of the main unit are connected to one end of the air valve and the second negative pressure tube of the disposable component, respectively. After the nasal cavity cleaning is completed, pipes one and two of the main unit are disconnected from one end of the air valve and the second negative pressure tube of the disposable component, and the disposable component is removed from the main unit.

[0008] The air valve is equipped with a T-shaped valve body.

[0009] The waste liquid bottle consists of a bottle body and a bottle cap, and a filter element is installed in the lower end of the waste liquid tube on the bottle cap.

[0010] An operation panel and control circuit are also installed inside the main unit. Beneficial effects

[0011] Compared with the prior art, the beneficial effects of this utility model's full-flow electric nasal irrigation system are as follows: 1. This utility model proposes a structural design where the diameter of the waste liquid pipe is larger than that of the inlet pipe. The inner diameter of the outlet is larger than that of the inlet; therefore, under the same flow rate, the flow velocity at the outlet will be lower than that at the inlet. According to Bernoulli's equation in fluid mechanics, if friction losses are ignored, reducing the diameter of the inlet pipe will increase the fluid velocity and decrease the pressure; that is, the pressure at the inlet will be lower than the pressure at the outlet. By optimizing the pipe diameter, the problem of high pressure exerted by the water flow on the nasal cavity is solved.

[0012] 2. An airlock is installed on the connecting pipe between the negative pressure pump and the waste liquid bottle. This airlock effectively solves the problem of gas backflow. Through the interlocking mechanism of the door and air pressure control, it ensures that when airflow passes between environments with different cleanliness levels or air pressures, the waste liquid in the waste liquid bottle and any harmful substances generated will not diffuse through the pipe to the negative pressure pump. The airlock is transparent and visible, allowing for immediate observation of whether waste liquid is flowing into its interior, enabling operators to handle the situation promptly.

[0013] 3. An air valve is installed between the positive pressure pump and the cleaning fluid bottle, and the air valve contains a T-shaped valve body. The structural design of the T-shaped valve body allows for flexible control of the flow direction and flow rate of the cleaning fluid.

[0014] 4. A filter element is installed in the tube between the nasal plug and the waste liquid bottle to prevent bacteria and viruses in the waste liquid bottle from entering the nasal plug through the waste liquid tube, thus protecting the cleanliness of the patient's nasal cavity.

[0015] 5. When this nasal irrigation system is used on multiple patients in a hospital, the used disposable component YC only needs to be removed from the main unit and replaced with a new disposable component. The more expensive main unit does not need to be replaced, thus the consumable costs for each patient's medical treatment are very low, greatly reducing the economic burden on patients.

[0016] In summary, through the above design, this nasal irrigation system is an effective rhinitis medical device that prevents cross-contamination and is suitable for reuse by multiple people in a hospital. Attached Figure Description
