[0018] Further, the commutation valve body includes a housing, a valve core 9, a silicone cap 10, a silicone plug 11 and a rotating handle 12. The first Luer connector 15, the second Luer connector 16 and the check valve 17 respectively communicate with the housing. The valve core 9 is embedded in the housing. The silicone cap 10 is fixedly connected to the valve core 9 and is located at the lower end of the valve core 9. The silicone plug 11 is embedded in the valve core 9.

[0019] Further, the thoracic puncture drainage device further includes a valve core baffle 18 and a housing baffle 19. The number of the valve core baffles 18 is two groups. The two groups of valve core baffles 18 are respectively fixedly connected to the valve core 9 and are respectively located at the lower end of the valve core 9. The housing baffle 19 is fixedly connected to the housing and is located on the outer wall of the housing.

[0020] Furthermore, the outer shell includes a main shell cavity 3, a first connecting pipe 4, a second connecting pipe 5, a third connecting pipe 6, a drainage connecting pipe 7, and a support block 8. The first connecting pipe 4, the second connecting pipe 5, and the third connecting pipe 6 are respectively communicated with the main shell cavity 3. The one-way valve 17 is embedded inside the first connecting pipe 4. The first Luer connector 15 is communicated with the second connecting pipe 5.

[0021] In this embodiment, the thorax of the patient is punctured by the puncture needle 2, and the drainage tube 1 is inserted into the thorax of the patient until the ends of the puncture needle 2 and the drainage tube 1 reach the effusion site.
