I

The drainage device contains flexible polymer tubes 1-3: inner 1 and outer 2 and 3 installed with a gap of approximately equal length. The inner tube 1 in the middle part is divided by partition 4 into two aspiration channels 5 and 6 and on both sides of the partition 4 has diametrically opposite the openings 7 and 8. The outer tube 2 is fixedly fixed by the proximal and distal ends on the inner tube 1, with the distal end fixed at the location of the partition 4. The tube 2 is diametrically opposite to the The perforations are 9, with a pair of perforations 9 arranged perpendicular to each other. The tube 3 is mounted telescopically on the tube 2, its proximal end passes into an auxiliary tube 10 mounted for movement on the tube 1. The tube 3 has six longitudinal perforations 11 circumferentially diametrically opposed to one another, of which at least one pair is displaced in about 25

During the aspiration of the exudate, air enters the annular channels 14 and 15 through the air ducts 16 and 17, which eliminates the suction of surrounding tissues to the outer tubes 2 and 3,

Drainage allows continuous irrigation of the cavity while maintaining drainage function. The irrigating fluid into the cavity is fed, for example, through the channel 5 of the tube 1, the holes 7 to the annular channel 14. Through the perforations 9 of the tube 2 and the holes formed when the perforations 9 and 11 of the tubes 2 and 3 are combined, the irrigating fluid is fed into during the supply of irrigating fluid duct 16 is closed with a plug. The washing liquid from the cavity is removed through the perforations 11, the annular channel 15, the openings 8, the aspiration channel 6 of the tube 1 and then in a random direction relative to the other-50 it flows into the collection vessel. During aspiral perforations 11. The tube 10 is provided with a flange 12, and the tube 1 has a removable sleeve 13 to restrict the tubes 3 and 10. The annular channels 14 and 15 respectively between the tubes 1.2 and 55 1.3 are provided with air ducts 16 and 17.

Drainage device operates as follows.

radio the air in the annular channel 15 enters through the open duct 17.

After completion of treatment, drainage is removed from the drainage cavity by known methods.

Life management; which part of the drainage allows to increase

Drainage is introduced into the abdominal cavity through additional incisions in the abdominal wall. The proximal ends of the tubes 1 and 10 and the air ducts 16 and 17 with the plugs are located outside. Holding the drainage by the coupling 13 and the flange 12, the tubes 10 and 3 are displaced in the direction of the coupling 13, adapting the working part of the drainage according to the length of the drained cavity. Then, the proximal ends of the tubes 1 and 10 are fixed to the abdominal wall by known methods, for example, using U-shaped seams, sleeves or dumbbell-visible cylinders, as shown in FIG. 9. The ends of the tube 1 are connected through a collection vessel (not shown) to a vacuum source. Exudate strips0
