The bottom of the limiting rod 18 is adapted to the limiting hole 19, and the limiting rod 18 plays a role in limiting the disinfection rod 13 to prevent accidental touching of the disinfection rod 13. A card slot 21 is provided on the annular through groove 20, and a sealing gasket is detachably connected to the inside of the card slot 21 22. The sealing gasket 22 is made of silicone. The sealing gasket 22 is used to ensure the sealing performance of the disinfection mechanism 4. The sealing gasket 22 is sleeved on the outside of the disinfection rod 13. The end of the disinfection rod 13 away from the sealing gasket 22 is fixedly connected with a connecting plate 23. The connecting plate 23 is arc-shaped and fits the outside of the annular through groove 20. The outside of the connecting plate 23 is fixedly connected with a blocking gasket 25. The blocking gasket 25 has mobile sealing performance. The size of the blocking gasket 25 is adapted to the through hole 24. The principle of disinfection achieved by the disinfection mechanism 4 here is: by pulling the pull cap 15 outward, the pull cap 15 drives the tension spring 14 and the disinfection rod 13 to move, and then drives the connecting plate 23 and the blocking gasket 25 away from the through hole 24, and then the disinfectant flows to the disinfection cotton 12 through the through hole 24. When the disinfectant is filled with disinfectant, release the pull cap 15, and the tension spring 14 automatically drives the disinfection rod 13 to reset, and then cooperates with the anti-blocking mechanism 5 to disinfect the outside of the drainage tube 1.

[0022] Embodiment 2: Figure 6 and Figure 7As shown, this is a further description of the first embodiment. In this embodiment, the anti-blocking mechanism 5 includes a square box 26, and a hole is opened inside the square box 26 to facilitate the drainage tube 1 to pass through. The upper symmetrical and movable connection of the square box 26 is provided with a push rod 27, and the ends of the two push rods 27 close to each other are fixedly connected with a pressing plate 28, and the pressing plate 28 is used to squeeze the drainage tube 1. The ends of the two push rods 27 away from each other pass through the square box 26 and are fixedly connected with a button 30. The ends of the two buttons 30 close to each other are fixedly connected with a compression spring 29. The compression spring 29 has an elastic effect, which is convenient for driving the button 30 to automatically reset. The ends of the two compression springs 29 close to each other are fixedly connected to the outer wall of the square box 26. By pressing the two buttons 30, the buttons 30 drive the push rod 27 and the pressing plate 28 to approach the drainage tube 1, thereby pushing the inside of the drainage tube 1. The pus and blood mixture moves downward to be unblocked. The outside of the square box 26 is fixedly connected to a mounting block 31, and a reciprocating screw 32 is rotatably connected to the mounting block 31. The reciprocating screw 32 has two sections of reciprocating threads. A knob 33 is fixedly connected to the top of the reciprocating screw 32, and the outside of the knob 33 is provided with anti-slip grooves. The outside of the reciprocating screw 32 is symmetrically threaded with a slider 34, and the outsides of the two sliders 34 are fixedly connected to arc plates 35, which are convenient for fitting with the surface of the drainage tube 1. The insides of the two arc plates 35 are fixedly connected to elastic pads 36, which are made of rubber to prevent the two arc plates 35 from fitting too tightly and affecting the drainage of the drainage tube 1. The two sliders 34 are slidably connected to the outer wall of the square box 26, and the square box 26 limits the slider 34 to ensure its horizontal movement.

[0023] For further information, see Figure 8 The anti-air intake component 6 includes a cylinder 37, and a filter membrane 38 is fixedly connected to the inside of the cylinder 37. The filter membrane 38 adopts a high-energy ray irradiation film. Particles pass through the membrane material and leave holes of uniform size. After post-processing, more precise impurities can be filtered. At the same time, a layer of water-permeable and air-impermeable material is provided on the outside of the filter membrane 38 to isolate air and prevent air from entering the drainage tube 1. An air outlet 40 is provided on the outside of the cylinder 37, and a breathable membrane 39 is fixedly connected to the inner side of the air outlet 40. Air can be discharged through the breathable membrane 39. At the same time, the breathable membrane 39 is made of a breathable and water-impermeable material. One end of the cylinder 37 and the side away from the air outlet 40 are fixedly connected to the end of the drainage tube 1, and the side of the cylinder 37 close to the air outlet 40 is fixedly connected to the connecting pipe 101. At the same time, the filter membrane 38 can prevent the discharged impurities from flowing back into the drainage tube 1, thereby enhancing the safety of the device and protecting the health of the patient.

[0024] In summary, when using this device, first pass the disinfection mechanism 4 and the anti-blocking mechanism 5 through the top of the drainage tube 1, then turn the knob 33, the knob 33 drives the reciprocating screw 32 to rotate, and then drives the two sliders 34 to slide, and then drives the two arc plates 35 to approach each other, so that the elastic pad 36 contacts the surface of the drainage tube 1, so that the disinfection mechanism 4 and the anti-blocking mechanism 5 are fixed on the outside of the drainage tube 1, when the doctor sutures one end of the drainage tube 1 to fix it on the patient's skin, then stick the tape 7 on the patient's skin, and use the adhesive tape 7 to fix the drainage tube 1 on the patient's skin. The buckle 8 fixes the drainage tube 1 on the surface of the tape 7, and then the elastic member 9 is put on the drainage tube 1 to prevent the drainage tube 1 from bending. When the surface of the drainage tube 1 needs to be disinfected, first pinch the handle 17 to make the limit rod 18 away from the limit hole 19, and then pull the pull cap 15 outward, the pull cap 15 drives the tension spring 14 and the disinfection rod 13 to move, and then drives the connecting plate 23 and the plugging pad 25 away from the through hole 24, and then the disinfectant flows to the disinfection cotton 12 through 24. When the disinfection cotton 12 is filled with disinfectant, release the pull cap 15, the tension spring 14 drives The disinfection rod 13 is reset, and then the drainage tube 1 is disinfected together with the anti-blocking mechanism 5 to ensure the sterility of the drainage tube 1. When the pus and blood mixture appears inside the drainage tube 1 and blocks the drainage tube 1, the arc plate 35 is loosened to move the anti-blocking mechanism 5 to the end of the blocking position, and then the two buttons 30 are pressed. The buttons 30 drive the pressing rod 27 and the pressing piece 28 to approach the drainage tube 1, and then push the pus and blood mixture inside the drainage tube 1 downward to clear it. When there is too much fluid in the drainage bag 41 and it needs to be discharged, the drainage cover 42 is opened to The internal accumulated liquid is poured out. At the same time, air may enter the drainage bag 41 through the drain cover 42 and then enter the drainage tube 1. Then, when the air enters the connecting tube 101, the filter membrane 38 will block the air to prevent the air from entering the drainage tube 1. Then, the gas will be discharged from the interior of the cylinder 37 through the breathable membrane 39 and the air outlet 40, thereby reducing the risk of air embolism. At the same time, the filter membrane 38 can prevent the accumulated liquid from flowing back when the internal accumulated liquid of the drainage bag 41 is poured out, thereby playing a secondary protection role.
