[0027] By setting the negative pressure pipeline 100 and the normal pressure pipeline 200 side by side, the insertion end a of the negative pressure pipeline 100 and the insertion end a of the normal pressure pipeline 200 can be simultaneously inserted into the drainage position during use, and the doctor can select the corresponding pipeline according to the patient's condition, wherein the idle pipeline can be closed by the negative pressure on-off piece 101 or the normal pressure on-off piece 102.
[0028] When the flushing function needs to be realized, the normal pressure on-off piece 102 is closed, the negative pressure on-off piece 101 is opened, the injection needle filled with the flushing liquid is inserted through the lead-through piece 103 and is pushed, optionally, the flushing liquid is normal saline, and after the flushing liquid enters the drainage position through the normal pressure pipeline 200, it flows out through the negative pressure pipeline 100.

[0033] In order to avoid the needle of the through-connection member 103 from being too long to extend into the normal-pressure opening and closing member 102, causing the needle and the inner wall of the normal-pressure opening and closing member 102 to be extruded, resulting in damage to the needle, further, the inner side of the normal-pressure opening and closing member 102 is provided with a protective member 104, which is located on the side of the outlet 1021 away from the inlet 1022.
