The advantage of this method is that it conforms to the characteristics of slow absorption of large doses of traditional Chinese medicine preparations, plays an active role in the treatment of nasal diseases with traditional Chinese medicine, and reduces the large-scale use of antibiotics and hormones.

[0060] As Figure 1 、 Figure 2 、 Figure 3 and Figure 4 shown, a nasal cavity flushing and circulating system provided by the present application includes at least one flushing pump 1, at least one suction pump 2, a flushing pipeline system and a circulating pipeline system;

[0061] The output end of the flushing pump 1 is used to supply liquid to one side of the nasal cavity; the input end of the suction pump 2 is used to extract liquid from the other side of the nasal cavity.

[0062] The flushing pipeline system includes: a first liquid supply pipeline 9 and a first discharge pipeline 3. Among them, the first liquid supply pipeline 9 is connected between the liquid supply tank 4 and the input end of the flushing pump 1, so that the flushing pump 1 can extract the first liquid from the liquid supply tank 4 through the first liquid supply pipeline 9. The first discharge pipeline 3 is connected between the waste liquid tank 5 and the output end of the suction pump 2, so that the suction pump 2 can discharge the waste liquid extracted from the nasal cavity into the waste liquid tank 5 through the first discharge pipeline 3.

[0063] The circulating pipeline system includes: a second liquid supply pipeline 6 and a second discharge pipeline 7. Among them, the second liquid supply pipeline 6 is connected between the circulating tank 8 and the input end of the flushing pump 1, so that the flushing pump 1 can extract the second liquid from the liquid supply tank 4 through the second liquid supply pipeline 6; the second discharge pipeline 7 is connected between the circulating tank 8 and the output end of the suction pump 2, so that the suction pump 2 can discharge the circulating liquid medicine extracted from the nasal cavity into the circulating tank 8 through the second discharge pipeline 7, facilitating the recycling of the liquid medicine. In addition, a filtering device is provided in the circulating tank 8, and structures such as a filter screen can be used. The filtering device filters the liquid entering the circulating tank 8.

[0064] When in application, taking the first liquid as physiological saline and the second liquid as Chinese / western medicine treatment agents or disinfectants as an example;

[0065] In the flushing mode, the flushing pump 1 extracts the first liquid through the first liquid supply pipeline 9 and supplies it to one side of the nasal cavity, and the suction pump 2 discharges the liquid extracted from the other side of the nasal cavity into the waste liquid tank 5 through the first discharge pipeline 3; in this mode, substances such as secretions, crusts, inhaled pathogenic sources, and autogenous pathogens in the patient's nasal cavity can be removed, and it can also clean the nasal cavity environment for the next circulating mode, reducing the quantity and concentration of pollutants during the circulation process.

[0066] In the circulating mode, taking the second liquid as Chinese / western medicine treatment agents as an example, the flushing pump 1 extracts the second liquid through the second liquid supply pipeline 6 and supplies it to one side of the nasal cavity, and the suction pump 2 discharges the liquid extracted from the other side of the nasal cavity into the circulating tank 8 through the second discharge pipeline 7; in this mode, drug circulation treatment can be carried out, enabling the drug to fully contact the nasal mucosa and meeting the treatment requirement of sufficient contact time of the drug with the nasal mucosa.

[0067] Taking the second liquid as the disinfectant solution as an example, the flushing pump 1 extracts the second liquid through the second liquid supply pipeline 6 and supplies it into one side of the nasal cavity, and the suction pump 2 discharges the liquid extracted from the other side of the nasal cavity to the circulation tank 8 through the second discharge pipeline 7; in this mode, the second liquid is a medical disinfectant solution. After the circulation process reaches the specified time length, the pathogenic sources and pollutants attached to the inner wall of the pipeline in the pipeline system will be removed to meet the requirements of medical disinfection standards.

[0068] In the nasal cavity flushing and circulating system in this solution, due to the first liquid supply pipeline 9 and the first discharge pipeline 3 in the flushing pipeline system, the second liquid supply pipeline 6, the second discharge pipeline 7, the liquid supply tank 4, the circulation tank 8 and the waste liquid tank 5 in the circulation pipeline system are all independent of each other, which can effectively alleviate the problem that the pipelines inside the equipment providing the circulating kinetic energy in the prior art cannot be replaced, and there is a risk of cross-infection when different medicaments are used in the same pipeline system.
