However, the single-head drainage bag has the following problems in actual clinical applications:
[0003] (1) Clinical micro-puncture drainage tubes, such as pleural effusion, bile drainage, pericardial effusion drainage, etc., are all hard-jointed drainage tubes and cannot be directly connected to the pagoda connector. Therefore, a conversion connector (such as a three-way connector) is required to connect a single-head drainage bag to such a drainage tube, which is inconvenient to use;
[0004] (2) The inner diameter of the three-way head is the same as that of the syringe nozzle, about 2 mm, while the inner diameter of the large-diameter drainage tube is greater than 2 mm, so the drainage is often blocked at the adapter;
