The invention is intended for secure emptying of organism's cavities, particularly for colon decompression. The secure emptying of cavity is ensur ed by a hose (19) with punctures, placed in drain (17). The liquid, feeding int o hose, realizes drain's recanalization, irrigates its holes and dilutes cavit y contents. Transportation of drain into colon is ensured by synergy of two intubation forces. The vanguard force is generated by fluid pressure which everts invaginator, the rearguard (extraanal) - by "cylinder-piston" unit wi th a cuff. The hollow unit's piston acts as pneumatic carriage, but cuff is periodically joining with invaginator with drain or their intractor (20). Evacuation of contents is ensured by influx-and-extract method. The sequenti al connection of intractor and drain ensures not only intubation, but also contents' evacuation through both ends of drain.
