The invention relates to medical technology and concerns the construction of drainage devices used in surgery for the drainage of cavities.

The purpose of the invention is to reduce trauma to biological tissues when a drainage tube is inserted.

FIG. 1 shows a surgical drainage tube, general view; in fig. 2-5 are, respectively, sections A – A, B – B, B – B, D – G in FIG. one.

Surgical drainage tube contains worker 1 and non-working 2 areas. Bending polymer drainage tube 3 has an axial drainage channel 4, longitudinal outside

Drainage of the body cavity is fixed by known techniques, for example, by means of a dumbbell-shaped inflatable balloon. The nozzle section 15 is connected through a collection vessel g (not shown) to a vacuum source. The filtration of fluid from the drainable cavity is carried out through the openings 6 into the drainage channel 4.

The filtrate from the duct 4 of the drainage tube 3 is displaced by air entering the 10 channel 4 through the vent holes 14, the annular channel 13, the channels 7, the annular container 9, the olive 8 and the perforations 10 of the membrane 11, into the collecting container for metering. .tj ... torus control. The process of aspiration sleepy ribs 5, for example, in the amount of scape. 5 Keeping the drainage cavity in control. Perhaps the spiral position of the ribs 5 by blocking the ventilation.

(not shown). The tube 3 in the working area 1 between the ribs 5 has drainage holes 6. The ribs 5 have through channels 7. At the distal end of the pipe 3, the tightness 9 communicates with the channels 7 and the drain channel 4 through perforations 10 of the diaphragm 11 located perpendicular to the long axis of the pipe . At the end of the non-working section 2 of the drainage tube, a rigid tubular nozzle 12 of variable cross section is formed tightly, forming an annular channel 13, through which the vent openings 14 that are diametrically located 14 communicate with the surrounding space. The channel of the end portion 15 of the nozzle connected to the end of the tube 3 is a continuation of the drainage channel 4.

Drainage tube works as follows.

The perforated working section 1 of the tube is inserted into the body cavity, while the non-working section 2 with the nozzle 12 is located outside. In the inlet
