Specifically, when the plurality of suction holes 506 arranged on the suction strip 505 block some of the suction holes 506 with waste blood, other suction holes 506 can still inhale air, and at the same time, the suction strip 505 will not suck the waste blood into the suction cylinder 503.

[0044] See also Figures 1 to 8 A vent hole 507 is provided inside the air suction block 504, and a limiting frame 508 is provided in the air suction hole 507. A rubber cover 509 is fixedly installed on one end of the limiting frame 508 close to the air suction strip 505. An absorbent cotton 510 is provided on the inner wall of the rubber cover 509. The absorbent cotton 510 is an expandable sponge that absorbs water and expands in the prior art. The expandable sponge allows waste blood to flow into the air suction block 504. When it needs to be transferred to the air suction cylinder 503, the absorbent cotton 510 absorbs the waste blood and expands it. After the absorbent cotton 510 expands, it opens the rubber cover 509, so that the rubber cover 509 fits against the inner wall of the vent hole 507, thereby closing the air suction block 504 and preventing the waste blood from being transferred to the compressed airbag 301 through the air suction block 504.

[0045] See also Figure 5The blood drainage mechanism 4 includes a blood drainage cylinder 401, and the blood drainage cylinder 401 is fixedly installed on the end of the collecting cylinder 101 away from the drainage tube 1, and a water hole 402 is opened at the end of the blood drainage cylinder 401 away from the collecting cylinder 101, and a rotating cover 403 is rotatably installed at the end of the blood drainage cylinder 401 away from the collecting cylinder 101, and a blood drainage hole 404 that matches the water hole 402 is provided at the upper end of the rotating cover 403. Specifically, when blood drainage is needed, the rotating cover 403 is rotated to make the blood drainage hole 404 set on the rotating cover 403 rotate to the side of the water hole 402 and match the water hole 402, so that the blood drainage cylinder 401 is opened to start bleeding.

[0046] The working principle of the present invention is as follows: when the drainage tube 1 needs to be installed, the drainage tube 1 is fixedly placed at the wound suture of the patient, the limiting ring 201 is moved to a suitable position, the fixing patch 203 is adhered to the patient's skin, the limiting rope 202 is pulled, the limiting ring 201 is fixed at a suitable position of the patient's body, the retaining ring 207 is moved, and the special-shaped ring 206 is rotated, so that the adhesive layer provided on the special-shaped ring 206 contacts the drainage tube 1, so that the limiting ring 201 fixes the drainage tube 1, thereby preventing the drainage tube 1 from falling off when the patient moves or accidentally touches the drainage tube 1;

[0047] After installation, the vent valve 502 is squeezed by hand to open the vent valve 502, and the compressed air bag 301 is squeezed. After squeezing, the vent valve 502 is closed to change the air pressure in the collection tube 101 to negative pressure, so that the dirty blood in the patient's wound is transferred to the collection tube 101 through the drainage tube 1. When a certain amount of waste blood is collected in the collection tube 101, the rotating cover 403 is rotated to make the water hole 402 communicate with the blood discharge hole 404, and the vent valve 502 is opened to discharge the dirty blood. After the discharge is completed, the compressed air bag 301 is squeezed and the vent valve 502 is closed, so that the blood discharge metering operation of the drainage tube 1 is more convenient;

[0048] When the drainage tube 1 is in use, waste blood flows into the suction block 504 and needs to be transferred to the suction cylinder 503, the absorbent cotton 510 absorbs the waste blood and expands. After the absorbent cotton 510 expands, it opens the rubber cover 509, so that the rubber cover 509 fits on the inner wall of the vent 507, thereby closing the suction block 504 and preventing the waste blood from being transferred to the compression airbag 301 through the suction block 504.

[0049] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto.
