[0002] On clinic, more patients are retained thoracic cavity closed drainage tube after thoracic surgery, and the size and model of catheter are different, for many pyothorax patients, 3 liters of physiological saline is needed for continuous use after operation to flush thoracic cavity, but there is lack of infusion apparatus connected with chest drainage tube on clinic, and most of them are connected by self-made connecting tube on clinic, but it cannot guarantee aseptic requirement.

[0003] Later, a kind of clinical infusion three-way is invented based on the principle of clinical infusion three-way, which is used for clinical thoracic flushing, and avoids waste and infection caused by repeated disassembly of drainage bottle. Clinical infusion three-way has one inlet and two outlets, and by controlling the position of internal valve core, liquid can flow out from different outlets. When it is applied to pipeline connection, it can reduce the complexity of pipeline, so it is widely used in infusion device. When clinical infusion three-way is used, the position of internal valve core needs to be changed by manually rotating the rotary switch on three-way valve, so as to realize the change of liquid flow direction in three-way valve.

[0004] The existing clinical infusion three-way has the following shortcomings: 1. The existing rotary switch is generally cross-shaped, and it is difficult for beginners to correspond the position of rotary switch to the position of open port when rotating the rotary switch, so that the user cannot quickly open the corresponding port according to his own needs; 2. The outlet of three-way infusion valve is generally connected with chest drainage tube and drainage bottle, and the hole diameter of chest drainage tube and drainage tube will be different due to different models, so different three-way infusion valves need to be used, which is inconvenient to use and operate.
