Abstract

The invention relates to medical technology, in particular to surgical facilities, and is purposed for drainage of different cavities. A drainage device is made of two coupled tubes, at the lower drainage tube a circular small hollow container is fixed, which by means of small adapter sleeve is connected to the upper hollow tube with of half as much diameter, which by means of large adaptor sleeve is connected to large hollow container. At the distal end of the device between lower drainage tube and the circular small hollow container a slit is made equal by width and length to the diameter of the lower drainage tube. At the proximal end between the lower drainage tube and large hollow container a slit is made equal by width and length to the half diameter of the lower drainage tube. Inside the large hollow container a swab is arranged, this is mounted on the rod which passes through the walls of this container and to which from one side a handle for swab rotation is fixed outside the container, and from another side in the rod a threaded canal is made, where a stop screw is arranged. Inside the circular hollow small container a ball is arranged, this is fixed to the thread passing from the small hollow container through the distal slit in proximal direction and then through the proximal slit inside the large hollow container, wherein it coils round the swab, and through the large adapter sleeve, upper hollow tube, small adapter tube it passes to the small hollow container, wherein it is fixed to the opposite ball pole. The ball diameter is a little less than inner diameter of the lower drainage tube to provide free movement thereof through the tube.
