Preferably, a floating sheet 18 is fixedly connected to the inner side wall of the collection chamber 11 at the outer side of the drainage tube 16 (i.e. the portion of the inner side wall of the collection chamber 11 between the drainage tube 16 and the sealing sticker 15), the floating sheet 18 is a flexible sheet material with density less than that of water, one end of the floating sheet 18 is fixedly connected to the inner wall of the collection chamber 11, and the whole floating sheet covers the communication opening between the drainage tube 16 and the collection chamber 11, so that when drainage fluid is collected in the collection chamber 11, the floating sheet 18 floats on the surface of the drainage fluid under the buoyancy of the drainage fluid, when the valve 17 is opened, when the drainage fluid is discharged from the collection chamber 11 due to the negative pressure generated in the drainage bag, since the valve 17 is opened for a short time (since the drainage fluid is discharged from the collection chamber 11 at a fast speed, the opening time of the valve 17 is short) and the floating sheet 18 has a certain isolation effect on the gas in the collection chamber 11, so that the drainage liquid is firstly discharged from the collection cavity 11, and a small amount of gas in the collection cavity 11 is discharged from the collection cavity 11, and will not affect the air pressure in the collection cavity 11 (even if a small amount of gas is discharged from the collection cavity 11, the extrusion threaded rod 33 can be rotated reversely to drive the extrusion circular plate 42 to slide towards one end of the interior of the collection cavity 11 (i.e. the extrusion circular plate 42 slides towards one end close to the skin in the annular frame 4), because a closed space is formed in the collection cavity 11, the air pressure in the collection cavity 11 is higher than the air pressure in the interior of the human body), when the drainage liquid is discharged from the collection cavity 11, a small amount of drainage liquid remains on the floating piece 18 (the drainage liquid remains on the side where the floating piece 18 and the drainage pipe 16 are butted with each other, and will not flow into the skin of the human body, and will not affect the drainage port 13 and the skin near the drainage port), and when drainage liquid is discharged, the floating piece 18 is attached to the side wall inside the collection cavity 11 due to the negative pressure of the drainage bag, so that the floating piece 18 blocks one end of the drainage tube 16 inside the collection cavity 11, at this time, a small amount of residual drainage liquid on the floating piece 18 has a certain liquid sealing effect on the end of the floating piece 18 blocking the collection cavity 11, so that gas is not discharged from the collection cavity 11 in a large amount, that is, the relative positive pressure effect of the collection cavity 11 is not affected even if the valve 17 is closed tightly, in addition, after the floating piece 18 blocks one end of the drainage tube 16 inside the collection cavity 11, the valve 17 is opened briefly, so that a gas pressure difference is formed between the collection cavity 11 and the drainage tube 16 (due to the fact that the drainage tube 16 is connected with the drainage bag, so that the gas pressures in the drainage tube 16 and the collection cavity 11 are unbalanced, so that the gas pressure in the drainage tube 16 is less than the gas pressure in the collection cavity 11), so that the floating piece 18 is recessed into the drainage tube 16, by observing whether the floating piece 18 is recessed, it can be judged that when the gas pressure in the collection cavity 11 is opened when the valve 17 is opened, the valve 17, the gas pressure is more constant, and the negative pressure in the drainage tube is not increased, and the case that the valve 18 is not necessary to regulate the drainage tube 11, the negative pressure in the drainage tube 11, and the case that the negative pressure in the drainage tube 11, the existing drainage tube 11 is not necessary for the drainage tube. Correspondingly, when the atmospheric pressure change in collecting chamber 11 is great, need forward or reverse rotation extrusion threaded rod 33 to make it drive extrusion plectane 42 and slide in collecting chamber 11 to guarantee that the atmospheric pressure in collecting chamber 11 is higher than the inside atmospheric pressure of human body, through the atmospheric pressure difference that collects chamber 11 and human inside formation, can effectively reduce the drainage liquid and ooze, reduce the probability that the drainage liquid oozes from drainage mouth 13, the corresponding risk that has just reduced infection around drainage mouth 13.

The other drainage tube device provided by the invention comprises a drainage pipeline, wherein the drainage leakage collecting mechanism is connected to the drainage pipeline.
