The invention relates to medical technology, namely to surgical instruments, and is intended to clean the drainage tubes.

The closest to the invention, according to the technical standard, is a device for washing the inner surface of the tubes, containing a tubular body with o-rings C1.

The known device is unsuitable for washing drainage tubes with openings on the side surface.

The purpose of the invention is to flush the drainage tubes with lateral surfaces on the surfaces.

This goal is achieved by the fact that in the device for washing the inner surface of tubes containing a tubular with o-rings, the tubular body tia has one end of the plug between the o-rings, and at the other end - annular marks- applied with a step equal to the pitch of the drainage holes. tube.

FIG. 1 shows a device for washing the inner surface of the tubes; in fig. 2 - drainage tube to be processed; in fig. 3 and 4 - the sequence of cleaning the holes of the drainage tube.

The device consists of a tubular body 1 with one black end 2 fitted with sealing rings 3 between which they form a circular channel 4 with holes 5 connecting it with the inner longitudinal channel 6. On the outer surface of the other end of the tubular

Corps 1 has annular markings 7 in increments corresponding to a step hole 8 in the drainage pipe .9.

The device works as follows.

A tubular body. 1 with a closed end, 2 is inserted into the drainage tube 9 to the extreme mark 7 opposite to that. At the end of Tubular body 1, the channel 4 is installed against the openings 8 of the drainage tube 9. The cleaning of the openings 8 of the drainage tube 9 is carried out by supplying fluid through the internal longitudinal channel b of the tubular body 1 through the openings 5 and the circular channel 4, from which h The drainage tube exits the drainage cavity. After cleaning the holes 8 in the drainage tube, the tubular body 1 is displaced until the next mark 7 coincides with the end of the drainage tube 91 and the channel 4 at the distal end 2 of the tubular body 1. is installed against the holes 10 of the drainage tube -9. The washing of the apertures 1; 0 in the drainage tube 9 is carried out similarly to the apertures 8. The invention permits the washing of medical drainage tubes, and, namely, the openings on their lateral surfaces, which are quickly closed by blood clots, fibrin, hydrocotic tissues and others, and thus restore their functioning at any stage of drainage, which ensures complete outflow of the contents and irrigating substances, which favorably affects the outcome of the disease.
