The invention is intended for secure emptying of organism's cavities, particularly for colon decompression. The secure emptying of cavity is ensured by a hose (19) with punctures, placed in drain (17). The liquid, feeding into hose, realizes drain's recanalization, irrigates its holes and dilutes cavity 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 with 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 sequential connection of intractor and drain ensures not only intubation, but also contents' evacuation through both ends of drain.
