[0088] The working method of the present invention:

[0089] During drainage, the shut-off valve 900 on the drainage tube 200 is opened, the shut-off valve 900 on the flushing tube 300 is closed, the pump body is started to generate negative pressure, so that the reserved needle 120 extracts blood clots and muddy bile and flows into the inside of the drainage tube 200. Since the intensity of the negative pressure caused by the flow of blood clots and muddy bile is not too large to open the plugging cylinder 510, the blood clots and muddy bile will enter the inside of the drainage bag 700 along the drainage tube 200;

[0090] When cleaning the wound, the shut-off valve 900 on the drainage tube 200 is closed, the shut-off valve 900 on the flushing tube 300 is opened, the pump body is started, the pump body extracts the medicinal liquid and transports it to the inside of the flushing tube 300, and enters the inside of the outer housing 410, and is filtered through the filter screen 440. And when flushing the affected area, not too much flushing is required, so that the medicinal liquid cannot push the plugging ball 520 to move and open the plugging cylinder 510, and then the medicinal liquid flows out through the reserved needle 120 for cleaning;

[0091] When flushing the drainage tube 200, the shut-off valves 900 on the drainage tube 200 and the flushing tube 300 are closed, the pump body is started, the pump body extracts the cleaning liquid and transports it to the inside of the flushing tube 300, and accumulates and squeezes the plugging ball 520 inside the outer housing 410, so that the plugging ball 520 moves and stretches the elastic stretching rope 530, so that the plugging ball 520 opens the plugging cylinder 510, and the cleaning liquid enters the inside of the drainage tube 200 to clean the drainage tube 200.
