The invention relates to medical technology, in particular to devices used for the electrophoretic introduction of drugs into the tissues surrounding the endotracheal tube. five

The purpose of the invention is to reduce the complications of compression.

On figo 1 shows the proposed tube with a bloated cuff, a general view of |. On FIG. 2 is a section A-A in FIG. 1 O (non-working part of the tube); FIG. 3 a cut. FIG. 1 (working part of the tube at the location of the cuff) | and FIG. 4 is a section bb of FIG. 1 (tubes at the location of the cuff) Ji-5 in FIG. 5 is a variant of the embodiment of the cuff, in which the layers are dotted connected to the other; figure 6 - node I on i. 3 (the section of the tube at the location of the auxiliary channel and that of the 2-way); in FIG. 7 - Node II in FIG. 1, (part of the auxiliary channel).

The endotracheal tube has a housing 1, in the distal part of which 25, near the beveled end 2, there is a bilayer cuff 3, the inner layer 4 of which is made of an electrically conductive polymer material, and the outer layer 5 is corrugated, and there are holes 9 between the corrugations 6-8. the cavity 10 of the cuff fits the duct 11, equipped with an indicator of the degree of inflation in the form of a cartridge 12 and a pinhole 13. An auxiliary channel 15 fits the outer cavity 14 of the cuff, the outer section 16 of which is fitted with a plug 17, V Nala-15 current lead 18 is located, contacts the inner sleeve the conductive layer 4 and in its proximal part zakanchivayuschiysl hydrochloric contact 19 for connection to elektroforeti Ceska apparatus. In another embodiment of the cuff (Fig. 5), both its inner layers 4 are electrically conductive and 5 outer ones are point-to-point connected to each other, with the openings 9 of the outer layer located near the points 20 of the layer connection, the tracheal tube uses with this way.

Tracheal intubation is performed using known methods. After intubation, the trachea inflates the internal cavity 10 of the cuff, controls the degree of filling of the balloon indirectly by inflating the balloon indicator 12. Then, a syringe (not shown) is connected to the hole 21 of the outer section 16 of the auxiliary channel 15, and liquid drugs are introduced into the external cavity 14 of the cuff, whence, through holes 9, they penetrate to the respiratory tract mucous directly into the compression zone. The arrangement of the openings 9 between the corrugations 6-8 of the outer layer and near the places of 20 joining layers 4 and 5 makes it possible to bring medicinal substances to the mucous membrane, since the openings of the outer layer at the moment of supplying the solution of medicinal substances to the external cavity 14 do not contact with the mucous membrane because in the recesses of the unevenly blown outer layer 5..Contact .19 of the electrical power supply 18, which is in contact with electrically conductive layer 4 and is one of the electrodes, is connected to an electrophoretic apparatus. Another electrode of the electrophoretic apparatus is placed on the front surface of the patient's neck and proceed to the electrophoresis session. Electrophoresis of drugs can be carried out simultaneously with their introduction through the auxiliary channel 15. Removing the endotracheal tube from the respiratory tract is carried out in the conventional way after blowing the cuff 3. The location of the endotracheal tube in the respiratory tract is determined radiographically by the location of the radiopaque conduit 18, Suggested intubation tube allows electrophoresis of medicinal substances directly to the compression zone; the cuff of the adjacent tissues x ways to prevent and treat complications razvivayup1ies with a long stay of the endotracheal tube in the respiratory tract,
