Liquid assembly 3 includes a liquid collection bottle 31 located on one side of the front end of the second connecting pipe 24. The outer walls of both ends of the liquid collection bottle 31 are connected to two sets of symmetrical first connecting pipes 32. A vacuum assembly 4 is located on one side of the liquid collection bottle 31. The vacuum assembly 4 includes a connector 41 sleeved on the outer wall of the first connecting pipe 32. The front end of the connector 41 is connected to a second connecting pipe 42. The outer wall of the second connecting pipe 42 is sequentially connected to a one-way stop valve 44, a micro-adjustment valve 45, and a flow meter 46. The front end of the second connecting pipe 42 is connected to a vacuum pump 43.

[0029] The puncture assembly 1 also includes a first scale 13 on the outer wall of the needle tube 11, a sheath 12 is movably sleeved on the outer wall of the needle tube 11, a first adhesive ring 16 is provided at the front end of the sheath 12, and a second adhesive ring 17 is provided at the end of the handle 14 near the needle tube 11, which cooperates with the first adhesive ring 16. The first adhesive ring 16 and the second adhesive ring 17 are bonded to each other.

[0030] The insertion tube 21 is movably inserted into the first connecting tube 15. The outer wall of the first connecting tube 15 is threaded with a sleeve 22. The inner wall of the sleeve 22 is threaded to match the first connecting tube 15. The insertion tube 21 is fixedly inserted into the sleeve 22.

[0031] The second connecting pipe 24 is movably sleeved on the outer wall of one set of first through pipes 32, and the connector 41 is movably sleeved on the outer wall of another set of first through pipes 32. A positioning rod 33 is fixedly provided at the upper end of the outer wall of the first through pipe 32. A positioning sleeve 34 that cooperates with the positioning rod 33 is fixedly provided at the upper end of the outer wall of the second connecting pipe 24 and the connector 41. The front end of the positioning rod 33 moves through the positioning sleeve 34. A limit bolt is threaded into the upper end of the positioning sleeve 34. A through hole that cooperates with the limit bolt is opened at the front end of the positioning rod 33. The limit bolt moves through the through hole.

[0032] Two sets of symmetrical connecting ropes 35 are fixedly provided on the outer wall of the liquid collection bottle 31 at the upper end of the first connecting tube 32. The end of the connecting rope 35 away from the liquid collection bottle 31 is connected to a sealing plug 36, which can be movably inserted into the inner wall of the first connecting tube 32.

By activating the vacuum pump 43, the needle 11 is inserted into the location where fluid needs to be extracted from the patient. The insertion depth is determined by the first scale 13 to prevent excessive insertion and potential damage to organs. The extracted fluid is then transferred through the connecting seat. 23 and the second connecting pipe 24 enter the liquid collection bottle 31 through the first connecting pipe 32. When it is necessary to test the liquid in the liquid collection bottle 31, the limiting bolt at the upper end of the positioning sleeve 34 can be rotated to remove the positioning rod 33 from the positioning sleeve 34, so that the first connecting pipe 32 can be pulled out from the inner wall of the second connecting pipe 24 and the connector 41, thus completing the disassembly of the liquid collection bottle 31. In order to prevent the liquid from leaking out of the first connecting pipe 32 during the inspection process, the connecting rope 35 can be pulled to insert the sealing plug 36 into the first connecting pipe 32 to seal the first connecting pipe 32 and prevent the liquid from flowing out. The one-way check valve 44 can prevent the liquid from flowing back during the extraction process. The flow rate of the liquid extraction can be adjusted by the micro-adjustment valve 45, and the flow rate of the liquid extraction can be determined by the flow meter 46, making the liquid extraction process easy to control and more accurate.
