The pleural fluid mixture inside the drainage bag body 1 passes through the outlet channel 21 and the inlet 32 ​​and enters the interior of the first box 31.

[0036] In a preferred embodiment, the inlet 32 ​​and the cap 33 are connected by threads, wherein the inlet 32 ​​is provided with external threads on its outer circumferential side, and the bottom of the outlet channel 21 and the cap 33 are provided with internal threads on their inner circumferential side, so as to realize the threaded connection between the inlet 32 ​​and the cap 33 or the outlet channel 21.

[0037] A filter screen 34 is fixedly installed inside the first box 31 for filtering sediment; wherein the filter screen 34 is arranged perpendicular to the axial direction of the first box 31.

[0038] The bottom of the first box 31 is provided with a cover 35, which is used to collect and store the sediment inside the first box 31 when assembled with the first box 31. The bottom of the first box 31 and the cover are connected by threads. The bottom of the first box 31 is provided with external threads on the outer circumferential side, and the inner circumferential wall of the cover 35 is provided with internal threads, so as to realize the threaded connection between the cover 35 and the bottom of the first box 31.

[0039] In a preferred embodiment, an annular groove 36 is provided on the top surface of the bottom plate of the cover 35 corresponding to the bottom end of the first box 31, and an annular sealing gasket 37 is embedded inside the annular groove 36; the top surface of the annular sealing gasket 37 protrudes from the annular groove 36 after installation; after the cover 35 and the first box 31 are assembled, the sealing of the bottom end connection of the first box 31 is ensured by the annular sealing gasket 37, that is, the sealing effect is achieved by the top surface of the annular sealing gasket 37 pressing against the bottom end of the first box 31.

[0043] In a preferred embodiment, a drainage tube 5 is fixedly provided at the top of the drainage bag body 1; a speed regulator 6 is fixedly provided on the drainage tube 5 to control the speed of pleural effusion drainage; and a pluggable drainage head 7 is provided at the end of the drainage tube 5 located away from the speed regulator 6 and away from the drainage bag body 1.

[0044] The working principle of this utility model is as follows: In the initial state, the manual valve 22 is in the open state, the first box 31 is installed on the liquid outlet channel 21, and the second box 41 is installed at the bottom of the first box 31.

[0045] Specifically, remove the protective cap 33, screw the liquid outlet channel 21 into the liquid inlet 32, that is, install the first box 31 at the bottom of the liquid outlet channel 21, and then thread the top of the second box 41 to the bottom of the first box 31.

[0046] Then, the pleural effusion mixture is drained. The drainage speed of the pleural effusion mixture is adjusted by the speed controller 6. After the pleural effusion mixture enters the body of the drainage bag 1, it first gathers at the bottom of the body of the drainage bag 1, and then enters the first box 31 through the outlet channel 21 and the inlet 32. After the pleural effusion enters the first box 31, the sediment in the pleural effusion mixture is separated by the filter screen 34 and placed above the filter screen 34. The pleural effusion then flows through the filter screen 34 and enters the second box 41. When the amount of sediment and pleural effusion reaches the requirements for testing, the manual valve 22 is closed. At this time, the outlet channel 21 is blocked. The first box 31 and the second box 41 are removed as a whole. The protective cap 33 is installed on the inlet 32. Then, the second box 41 is unscrewed and separated from the first box 31. The cap 35 is threaded to the bottom of the first box 31 to complete the collection of sediment. The protective cap 33 can be opened again, and formalin or other liquids can be added through the inlet 32 ​​to fix the specimen. After screwing on the protective cap 33, the specimen is sent for testing.

[0047] Then screw the plug 42 into the top of the second box 41 to complete the collection of pleural fluid;

[0048] The entire operation is simple, convenient, and environmentally friendly; it avoids the traditional method of cutting open the drainage bag, and also avoids the problem of pleural fluid leakage and environmental pollution caused by cutting open the drainage bag.
