Description

The invention relates to the medical technology and can be used in phthisiology.

A device for injecting powdered substances is known, comprising a tube and a spring-loaded reflector of a cone- ⁵ shape [1].

A disadvantage of the known device is the repeated repetition of puncture tissue of the lung.

The purpose of the invention is the elimination of repeated punctures of the lung tissue.

The goal is achieved in that the device comprises a tube and a spring loaded conical reflector, on the working end of the tube ¹⁵ are made nye longitudinal grooves and springs are formed as loops and arranged at the same distance from each other, wherein one end of each spring is connected to an external side of the reflector, and the other - fixed 20 in the longitudinal groove on the outside of the tube.

In addition, at the base of the reflector there are slots arranged corresponding to the longitudinal grooves of the tube.

FIG. 1 schematically shows a device for the introduction of powdered substances, top view; in fig. 2 is a section A-A in FIG. one.

Device for the introduction of powdered substances contains a cylindrical tube 1 with longitudinal grooves 2 and an end opening 3, which closes the reflector 4, having a tapered shape with the apex facing the lumen of the tube. The reflector 4 is equipped with springs 5, made in the form of loops and located at the same distance from each other, one end of each spring is connected to the outside of the reflector 4, and the other is fixed in the longitudinal groove 2 of the tube. At the base of the reflector 4 are made slots 6.

The device is introduced into the cavity through the lumen of the trocar with the help of a stylet, which has a deepening conical shape at the working end. The stylet is inserted into the tube 1 before connecting the recess to the cone of the reflector 4, while the springs 5 enter the grooves 2 and the slits 6, and is displaced to the tension of the springs 5. In this position, the device is inserted through the trocar case

in the cavern. After the introduction of the working part of the device into the cavity, the stylet and trocar case are removed from the body.

In the process of spraying under the action of the air flow generated by the pressure source, the reflector 4 is displaced along 5 of the longitudinal axis of the tube 1, opening the hole 3, and the powder trapped by the air flow is thrown by the air jet onto the walls of the cavity. When the air pulse is weakened, the reflector 4 returns to its initial position under the action of springs 5, isolating the catheter channel from the humidified cavity cavity by 1 °. After the administration of the required dose of the drug to the tuberculosis cavity, the outer end of the tube 1 is fixed to the patient's body until the next session of drug administration ..

The design of the proposed device provides long-term fixation of the sputtering tube in the cavity, which eliminates the need for repeated painful transthodical puncture tuberculosis 10 caverns, reduces the time of treatment of cavernous tuberculosis.

Claims (2)
