The invention relates to medical technology, and concerns the construction of devices used in surgical practice for the drainage of cavities and wounds.

The aim of the invention is to ensure tightness when changing the working length of the tubes during the drainage process. 1 shows a drainage device having several drainage devices.

The drainage device (see Figures 1-5) contains flexible polymer drainage tubes 1, each of which has a DL one through longitudinal channel 2 and a longitudinal groove 3, The device is equipped with a means of mounting in the form of a plug A in the inlet to the body cavity with a flange 5 of elastic material with longitudinal channels 6 in the form of shaped slots, the cross sections of which are congruent to the cross sections of the drainage tubes 1. This ensures tight fixation and the possibility of moving the draining tubes 1 relative to but flange 5. The flange 5 has transverse channels 7, to which additional tubes 8 are connected. The channels 2 of the drainage tubes 1 through the grooves 3 and the transverse channels 7 of the flange 5 communicate with the additional tubes 8. The drain tubes 1 on the outer surface have control lines on their outer surface. tags 9. i-.

can be made with one drainage tube 1 with four through longitudinal channels 2, which communicate 55 with the surrounding space through the longitudinal grooves 3. The flange 5 has a horizontal channel 10 that communicates through the grooves 3 with the channels 2 of the drainage

tubes 1. an additional tube 8 is connected to the flange 3 along with a closed channel 10. A through axial channel 11 is provided in the drainage tube 1, to the proximal end of which is attached an auxiliary tube 12 with a cannula 13 under the syringe and cap 14.

The device is used as follows.

The distal portions of the drainage tubes 1 are inserted into the wound canals, while the stopper 4 is located at the inlet to the body cavity, and the flange 5 with the additional tubes 8 and proc. The maximal ends of the drainage tubes are located outside and fixed on the surface of the body by known techniques, for example, using an adhesive film. The ends of the additional tubes 8 are connected to collection vessels (not shown) to account for the amount and nature of the area to be separated from the different parts of the drainage area. The outflow of fluid from the wound is carried out through the longitudinal grooves 3, the channels 2 of the distal sections of the drainage tubes, the transverse channels 7 and the additional tubes 8 (see Fig. 5) into collection vessels. To irrigate the drained wound through one or. Several additional tubes 8 supply the solutions of the drugs, while the outflow of the washing liquid is carried out through the remaining additional tubes. This makes it possible to increase the efficiency of wound drainage. If it is necessary to regulate in the course of treatment, the lengths of the distal parts of the drainage tubes located in the wound canals tighten or insert the corresponding drainage tubes into the wound canals, while holding them at the proximal ends. When moving the drainage tubes 1, the tightness of the channels 2 of the drainage tubes 1 and their fixation is provided. In the course of treatment, as the number of the separated pathological area decreases, the drainage tubes 1 are gradually removed from the canals, orienting themselves along the check marks 9, thus ensuring the gradual healing of the corresponding wound channel from the bottom. When removing the drainage tubes 1 from the wound in the longitudinal channels 6 of the flange 5, the drainage tubes are left for

preserve the tightness of the device and the drainage function. As the drainage tubes 1 are removed from the wound canals, the proximal ends are cut for convenience, leaving small areas outside. The gradual extraction of the distal sections of the drainage tubes from the wound canals while maintaining the drainage function ensures the gradual healing of the wound canals. Surgical drainage after treatment is removed by conventional treatment.

A drainage device with a single drain tube (6–11) is used similarly. The outflow of fluid from the wound is carried out through the longitudinal grooves 3, the longitudinal channels 2 of the drainage tube 1, through the JK channel 10 of the flange 5 and the additional tube 8 (Fig. 11). For irrigation of the bottom of the drained wound, solutions of medicinal substances are fed through the axial channel 11.

The drainage device, due to the preservation of tightness when changing the working length of the tubes during the drainage process, is highly versatile and effective.
