A rubber sheet 36 is fixedly connected to the inside of the slip ring 33. The wire 5 is inserted into the inside of the rubber sheet 36.

[0024] Specifically, a button plate 35 is fixedly connected to the outer side of the slip ring 33. The button plate 35 is located on one side of the guide tube 1. The button plate 35 can cooperate with the slip ring 33 to facilitate the worker to adjust the sliding of the slip ring 33.

[0025] Specifically, a guiding device 4 is provided on the outside of the guiding tube 1. The guiding device 4 includes a connecting block 44, which is fixedly connected to the outside of the guiding tube 1 and is located below the pin 2.

[0026] In this embodiment, the connecting block 44 can cooperate with the guide tube 1 to support the connecting block 44.

[0027] In this embodiment: the outer side of the connecting block 44 is threaded with a threaded cap 42, which is located below the pin 2. The threaded cap 42 can cooperate with the connecting block 44 to achieve the purpose of restricting the threaded cap 42.

[0028] Specifically, an infusion tube 43 is fixedly connected to one side of the threaded cap 42, and the infusion tube 43 is connected to the connecting block 44.

The slip ring 33 pushes the spring 32. When the spring 32 slides, it is affected by the cavity 31. The spring 32 gradually closes and clamps the wire 5. The spring 32 and the wire 5 block the cavity 31. The worker inserts the needle 2 into the patient's body. The patient's blood and body fluids will flow into the needle 2. The spring 32 and the wire 5 will block the blood and body fluids. After the blood and body fluids flow away through the guiding device 4, the button 35 is released. The return spring 34 releases the seal and pushes the wire 5. The wire 5 is affected by the rubber sheet. The guide device 36, through the setting of the sealing device 3, can effectively facilitate the worker to seal off blood and body fluids, preventing blood and body fluids from flowing into the worker's hands and the puncture equipment, thus making it easier for the worker to observe and use the puncture equipment. In addition, through the setting of the guide device 4, when the worker needs to clean the blood and body fluids in the needle 2 and the guide tube 1, the guide port 41 guides the blood and body fluids into the connecting block 44, the connecting block 44 guides the blood and body fluids into the threaded cap 42, and the threaded cap 42 guides the blood and body fluids into the infusion tube 43. By setting the guide device 4, the worker can effectively guide the outflowing blood and body fluids, preventing blood and body fluids from affecting the worker's use of the puncture equipment, thus improving the worker's convenience in using the puncture equipment.
