Triangular blocks are provided on both sides of the top of the convex buckle 29. Only when the user pulls the pressure rod 22 with force can the pressure rod 22 be separated from the convex buckle 29. When the pressure rod 22 fits with the bottom rod 28, the drainage tube 2 is sealed to stop the suction of body fluids.

[0034] Working principle:

[0035] When in use, the medical staff can hang the device on an object next to the patient through the hanging handle 3, and then rotate the fastening rod 5 to press the square piece 6 against the surface of the hung object. Continuously rotating the fastening rod 5 can press the hung object and the silicone bottle 1, so as to slightly fix the position of the silicone bottle 1; the medical staff first pulls out the sealing plug 25 in the air vent 26, and the sealing plug 25 is continuously hung on the fixing rod 24 to prevent the sealing plug 25 from being lost. Then the medical staff squeezes the silicone bottle 1 to discharge the air in the bottle from the air vent 26, creating a negative pressure state in the bottle, and inserts one end of the drainage tube 2 with the absorption hole 21 into the wound to absorb the body fluid in the wound. The absorption hole 21 can absorb the body fluid in other parts of the tube mouth, thereby accelerating the absorption speed. The body fluid flows into the silicone bottle 1 through the drainage tube 2 and the connecting tube 17. When the body fluid falls on the diaphragm 18, due to the body fluid itself The gravity of the body can open the diaphragm 18 downward. When no body fluid passes through, the elastic diaphragm 18 is reset to prevent the body fluid from flowing back. The buckle 19 fixedly connected to the outer wall of the connecting part of the drainage tube 2 and the connecting tube 17 cooperates with the protrusion 20 on the threaded cap 16 to prevent the drainage tube 2 from falling off. When the medical staff observes that a lot of liquid is collected in the silicone bottle 1 through the scale line 4, the pressure rod 22 can be pressed down to make the pressure rod 22 slide to the bottom rod 28 at the bottom, and the protruding buckle 29 is stuck into the two ends of the pressure rod 22. Triangular blocks are provided on both sides of the top of the protruding buckle 29. Only when the user pulls the pressure rod 22 hard can the pressure rod 22 be separated from the protruding buckle 29, and the sliding bar 23 between the pressure rod 22 and the bottom rod 28 can prevent the pressure rod 22 from being misaligned with the bottom rod 28. When the pressure rod 22 fits with the bottom rod 28, the drainage tube 2 is sealed and the body fluid is stopped from being sucked in.

[0036] The drain valve cap 13 in the drain device 7 is rotated to open the bottom of the drain pipe 8. The drain valve cap 13 is connected to the connecting ring 15 by the elastic rope 14, and the connecting ring 15 is fixed on the drain pipe 8 to prevent the fixing plate 11 from sliding toward the drain pipe 8 so that the rotating rod 10 does not contact the fixing plate 11. At this time, rotating the rotating rod 10 can drive the through-hole ball 9 to rotate so that the through-hole is vertically downward, and the body fluid in the silicone bottle 1 flows out from the drain pipe 8 and the through-hole ball 9. After a certain amount of body fluid flows out, the user rotates the rotating rod 10 to place the through-hole of the through-hole ball 9 horizontally. The through-hole ball 9 is provided with sealing rings 12 above and below to prevent liquid from leaking from the through-hole. Then, the fixing plate 11 is relaxed, and the fixing plate 11 is reset by the supporting spring 27. Then, the end of the rotating rod 10 away from the drain pipe 8 is stuck in the fixing plate 11, which can prevent the rotating rod 10 and the through-hole ball 9 from loosening and causing the through-hole position of the through-hole ball 9 to change.
