[0002] Endoscopic nasal surgery has become a routine operation in otolaryngology. After endoscopic nasal surgery, how to promote the early recovery of the surgical mucosa and prevent surgical cavity adhesion and sinus closure is an urgent problem to be solved in clinical practice. Nasal irrigation is an important measure to alleviate the above-mentioned postoperative complications.

[0003] The nasal irrigator in the prior art generates a water flow with flushing force when flushing the nasal cavity. The water flows into the nostril, flows through the nasal vestibule, nasal passages, sinus openings, nasopharynx, and flows out from the other nostril, flushing the mucus and foreign matter that enters the nasal cavity out of the nasal cavity. However, in this process, due to the different inclination angles of the nasal cavity, it is easy for the flushing liquid to flow out from the inlet cavity, and there is no collection device at the outlet cavity, which easily causes the waste liquid to flow out and cannot be collected, causing the waste liquid pollution problem.

[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] In the scheme of this application:

[0020] 1. In order to solve the problem in the prior art that when flushing the nasal cavity, the flushing liquid easily flows out from the inlet cavity due to the different inclination angles of the nasal cavity, and the waste liquid easily flows out without a collection device at the outlet cavity and cannot be collected, causing waste liquid pollution, the present application provides a reflux pipe, a flexible part, and a reflux hole at the flushing piece to return the liquid that has not flowed out of the other nasal cavity to between the reflux pipe and the flushing pipe, so that it flows into the collection cavity for collection. In addition, a collection pipe is provided for collecting the liquid medicine from the other nasal cavity so that it enters the collection cavity for collection, thereby realizing the collection of the liquid medicine and reducing pollution.

[0021] 2. The present application increases the sealing with the nasal cavity by setting a flexible part on the collection tube and the return tube, so that the flushing medicine liquid will not flow out of the nasal cavity, and the inclined setting of the inner wall of the second sealing plate and the setting of the return hole allow it to flow well into the collection cavity. The setting of the return tube separates the inner cylinder and the collection cavity.

[0022] 3. When the flushing member moves upward in the liquid cavity to flush the nasal cavity, it can drive the second sealing disk to move inside the air cavity to provide liquid to the liquid supply tube through the bottom of the flushing tube. The gas squeezed in the liquid cavity is output to the nasal cavity, thereby achieving the purpose of transporting the liquid medicine in the medicine cartridge to the nasal cavity, and realizing liquid supply and flushing.

[0023] 4. The threaded rod installed on the piston column moves in the air cylinder installed inside the active chamber, so that the gas extends through the negative pressure air tube to the bottom side of the collection tube and flows downward, generating negative pressure at the top of the collection tube, so that the liquid in the nasal cavity is sucked away and flows into the collection chamber, realizing flushing, liquid supply, and liquid suction at the same time.

[0024] 5. By setting a support plate sliding inside the cylinder handle, the piston column can be restored to its original position under the action of the second spring after the piston column is flushed, and then the support plate is pushed to retract and retract through the setting of the corners of the bottom surface of the piston column. When the piston column moves upward, the first spring installed inside the external groove drives the support plate back to the inside of the original active cavity, and the elastic force of the first gas control valve is greater than the elastic force of the first spring, thereby increasing the bottom placement force and supporting force when not flushing.

[0025] 6. Through the cleaning parts, when it is necessary to release the liquid collected in the collection chamber and after the liquid is released, the piston column can be moved upward to drive the cross plug to connect with the socket, and the rotating rod drives the connecting rod connected to the socket to rotate, thereby driving the cleaning scraper to rotate. The S-shaped cleaning scraper can scrape off the liquid stuck on the inner wall and clean the inside of the collection chamber. The rotation angle is 150 degrees, and the angle between the first gas control valve and the negative pressure air pipe is 60 degrees. BRIEF DESCRIPTION OF THE DRAWINGS

The setting of the second gas control valve 63 facilitates the subsequent entry of air into the air cylinder 62, the second one-way valve 641 can realize the one-way flow of gas, and the setting of the second spring 74 facilitates reset.

[0055] Further, such as Figure 2 、 Figure 6 、 Figure 9 As shown, the liquid supply part includes a liquid supply pipe 921, which extends to the interior of the air cavity 92, and the outer surface of the piston column 6 extending to the bottom of the air cavity 92 is installed with a second sealing disk 73, and the side of the liquid supply pipe 921 close to the air cavity 92 is respectively installed with a first gas control valve 94 and a fifth one-way valve 924, the top of the liquid supply pipe 921 extends to the interior of the flushing pipe 51, and the outer surface of the liquid supply pipe 921 close to one end of the flushing pipe 51 is installed with a fourth one-way valve 923, and the liquid supply pipe 921 is installed with a third one-way valve 922 on the bottom surface inside the medicine liquid cylinder 3.
