Description

(54) INTUBATION PIPE

one

The invention relates to medical technology, in particular to anesthesiology.

Known intubation tube, made in the form of an elastic tube with an inflatable cuff at the working end and air duct 1.

The disadvantage of this tube is that when it is used, trauma of the vocal cords is possible.

The purpose of the invention is to prevent the trauma of the vocal cords.

The goal is achieved by the fact that in the endotracheal tube, made in the form of an elastic tube with an inflatable cuff at the working end and an air duct, at the working end of the tube there are two symmetrical holes arranged at an acute angle to the longitudinal axis of the tube and forming a rounded edge, and inside the tube The holes have a profiled separating rib.

FIG. 1 shows the intubation tube; in fig. 2 shows section A-A in FIG. one.

On tube 1, inflatable cuff 2 with air duct 3 is located. At the working end 4, a profiled separating rib 5 is installed, forming two nozzles 6 and 7 with rounded edges 8 and 8.

After tube 1 is installed, a gas stream is introduced into the trachea. In the area of the separating rib 5, the total gas flow is divided into

 two streams directed to the main bronchi through nozzles 6 and 7. Consequently, the bifurcation of the trachea is relieved of the function of the gas flow divider, and the intensity of the blowing of the trachea bi10 is significantly reduced. This leads to a decrease in drying of the mucous membrane in the area of the trachea bifurcation. The proposed shape of the working end of the endotracheal tube largely corresponds to the shape of the glottis, with which it interacts, and is rounded so as not to contain sharp protrusions. In the process of intubation, the rounded edges of the tube 8 slide off the vocal lines, and thus their ruptures are eliminated.

20

The use of the endotracheal tube of the proposed design reduces the resistance to inhalation and reduces the turbulent gas cushion in the area of the trachea bifurcation.
