Abstract
Description
Technical Field
[0001] This utility model relates to the field of medical device technology, specifically to a nasal irrigation pot. Background Technology
[0002] Rhinitis refers to inflammation of the nasal mucosa, leading to congestion, swelling, and increased secretions, which in turn cause symptoms such as nasal congestion, runny nose, and sneezing. Nasal irrigation is an important adjunctive method in the treatment of rhinitis. It can remove secretions, allergens, bacteria, and viruses from the nasal cavity, reduce the inflammatory response of the nasal mucosa, and relieve rhinitis symptoms. Traditional nasal irrigation methods rely on gravity or manual pressure to inject saline solution into the nasal cavity for cleaning. However, this method has an unstable flow rate, which can easily cause patients to cough and choke, and it is also difficult to completely remove dirt from the nasal cavity.
[0003] To overcome the shortcomings of traditional nasal irrigation methods, existing technologies have developed devices specifically for nasal irrigation, providing patients with a better medical experience. For example, patent application number CN202121629390.0 discloses a rapid nasal and sinus irrigation device, including a reservoir, an outlet, a reservoir cap, and an outlet pipe. The outlet is heat-fused to the lower end of the reservoir, and the reservoir cap is threaded onto the surface of the outlet. The outlet pipe is heat-fused to the lower end of the reservoir cap, and a first fixing ring is heat-fused to the inner wall of the outlet pipe. A bracket is heat-fused to the middle of each fixed ring, and a collar is heat-fused to the middle of the bracket. A sliding rod passes through the middle of the collar, and a sealing block is welded to the bottom of the sliding rod. A spring is fitted onto the upper end of the sliding rod. One end of the spring is welded to the collar, and the other end of the spring is welded to a second limiting block, which is welded to the top of the sliding rod. The sliding rod moves the sealing block into the water outlet pipe, blocking the water outlet pipe to prevent backflow and improve the usability of the device. It also facilitates the fixing of the liquid storage tank, eliminating the need for the user to hold the liquid storage tank continuously, thus improving the convenience of the device.
[0004] While the aforementioned structure can achieve nasal irrigation for rhinitis patients, this device lacks a reflux mechanism, meaning the wastewater after nasal irrigation cannot be effectively recycled, leading to environmental pollution. Furthermore, if the patient has infectious rhinitis, the wastewater after irrigation increases the risk of cross-infection. Therefore, a nasal irrigation device with wastewater recycling capabilities is needed to address these issues.

[0013] Furthermore, the flushing mechanism also includes a pump reservoir on the flushing pipeline, an upper check valve and a lower check valve installed on the flushing pipeline. The upper check valve is located above the pump reservoir, and the lower check valve is located between the pump reservoir and the storage tank, with its front opening facing the front of the pump reservoir.

[0026] This application provides a nasal irrigation pot, which solves the problem that existing nasal irrigation devices do not have a wastewater recycling function. To better understand the technical solution of this application, the above technical solution will be described in detail below with reference to the accompanying drawings and specific embodiments.
[0027] This example discloses a nasal irrigation pot; see [link to relevant documentation]. Figs. 1-4 The device includes a support mechanism 1, a flushing mechanism 2 mounted on the support mechanism 1, and a return box 3 installed inside the support mechanism 1. The support mechanism 1 includes a support cover 11, a collection groove 12 on the top of the support cover 11, and a limiting protrusion 14 fixed to the center of the collection groove 12. The flushing mechanism 2 includes symmetrically arranged flushing pipes 21, a liquid storage tank 25 connected to the lower end of the flushing pipes 21, and a flushing nozzle 26 installed on the upper end of the flushing pipes 21. The flushing pipes 21 are symmetrically arranged through the limiting protrusion 14, the flushing nozzle 26 is located above the limiting protrusion 14 with its end facing upward, and the liquid storage tank 25 is fixed inside the support cover 11. In the above technical solution, the liquid storage tank 25, the flushing pipes 21, and the flushing nozzle 26 are connected to realize the flushing of the nasal cavity. The support mechanism 1 also includes a front opening 111 on the front side of the support cover 11, a return port 13 at the bottom of the collection tank 12, and a bottom opening 15 at the bottom of the support cover 11. The front opening 111 is located directly in front of the rinsing mechanism 2. In the above technical solution, the front opening 111 facilitates manual operation and control of the rinsing mechanism 2.
[0028] The lower end of the flushing pipe 21 is connected to the bottom of the storage tank 25. A horizontal filling port 251 is also provided at the upper end of the storage tank 25, passing through the support cover 11 and extending beyond it. In this technical solution, the design of the filling port 251 extending beyond the support cover 11 facilitates the filling of flushing fluid into the storage tank 25. The flushing mechanism 2 also includes a pump reservoir 24 mounted on the flushing pipe 21, and an upper one-way valve 22 and a lower one-way valve 23 mounted on the flushing pipe 21. The upper one-way valve 22 is located above the pump reservoir 24, and the lower one-way valve 23 is located between the pump reservoir 24 and the storage tank 25, with the front opening 111 facing the front of the pump reservoir 24. The flow direction of both the upper one-way valve 22 and the lower one-way valve 23 is upward. In this technical solution, the pump reservoir 24, in conjunction with the upper one-way valve 22 and the lower one-way valve 23, allows for manual control of the flushing fluid flow rate.
[0029] The reflux tank 3 is fixed to the back of the storage tank 25. A reflux pipe 32 connects the reflux tank 3 and the reflux port 13. A drain plug 31 is rotatably installed at the bottom of the reflux tank 3, corresponding to the area above the bottom opening 15. In the above technical solution, the wastewater collected in the collection tank 12 can be recovered in a timely manner using the reflux tank 3 and the reflux pipe 32. Moreover, the recovered wastewater in the reflux tank 3 can be discharged by manually controlling the drain plug 31, facilitating centralized treatment.
[0030] Working principle: When implementing the device of this application, firstly, the medicine or saline solution for rinsing the patient's nasal cavity is poured into the storage tank 25 through the filling port 251; after filling is completed, the pump reservoir 24 is manually and intermittently squeezed through the front opening 111; since the pump reservoir 24 is equipped with an upper one-way valve 22 and a lower one-way valve 23 respectively, when the pump reservoir 24 is squeezed, the air inside it is discharged through the upper flushing pipe 21 and the upper one-way valve 22 and from the flushing nozzle 26; when the squeezing is released, the negative pressure inside the pump reservoir 24 generates suction, which is discharged through the lower flushing pipe The flushing fluid in the reservoir 25 is drawn into the pump reservoir 24 by the lower one-way valve 23 and the flushing line 21, and this cycle continues until the flushing line 21 is filled with flushing fluid and air is expelled. Then, the patient's nose is repeatedly brought close to the flushing nozzle 26 until the nozzle is inserted into the nasal cavity to be flushed. Next, the pump reservoir 24 is manually squeezed intermittently again. Under the restriction of the one-way flow by the upper and lower one-way valves 22 and 23, the flushing fluid is drawn out of the reservoir 25 and sprayed from the nozzle 26, thus achieving the purpose of nasal irrigation. The wastewater after flushing flows out of the patient's nasal cavity under gravity and into the collection tank 12. The flushing wastewater in the collection tank 12 flows back into the return tank 3 through the return port 13 and the return pipe 32, thus achieving the purpose of wastewater recovery after flushing. The timely recovery of flushing wastewater in this application not only avoids environmental pollution but also prevents cross-infection and improves the safety of the device. After rinsing is complete, unscrew the drain plug 31 at the bottom of the return tank 3 through the bottom opening 15, and then drain the wastewater stored in the return tank 3. This facilitates the centralized treatment of wastewater.
