Right double-lumen bronchial cannula

Abstract

The invention discloses a right double-lumen bronchial cannula, which comprises a first branch pipe, a second branch pipe, a first air sac and a second air sac. The right double-lumen bronchial cannula is characterized in that the first branch pipe and the second branch pipe are vertically arranged in a clinging manner; the pipe wall of the first branch pipe is fixedly connected with the pipe wall of the second branch pipe; further, upper-end pipe orifices of the first branch pipe and the second branch pipe are flush with each other; a lower-end pipe orifice of the first branch pipe is an inclined plane, and supports the breath of a left lung; a bent branch pipe is arranged at the lower end of the second branch pipe and is moreover located at the lower-end pipe orifice of the first branch; the central axis of the bent branch pipe and the extension axes of the first branch pipe and the second branch pipe are at an angle; the length of the bent branch pipe is 1.5 to 2 centimeters; a pipe orifice of the bent branch pipe is an inclined plane, and supports the breath of a right lung. The first air sac wraps the outer walls of the first branch pipe and the second branch pipe, and closes a main airway. The second air sac wraps the outer wall of the bent branch pipe at the lower end of the second branch pipe, and is used for closing a right main bronchus. The right double-lumen bronchial cannula has the advantages that the resistance during right single-lung ventilation is relieved; meanwhile, the work load of an anesthesiologist is also reduced.

Description

technical field [0001] The invention belongs to the technical field of medical devices, in particular to a right double-lumen bronchus intubation tube. Background technique [0002] There are two types of double-lumen bronchial intubation, left and right, but hospitals are generally willing to use the left double-lumen bronchial intubation. It is whether the vent hole of the right upper lobe of the right double-lumen bronchus can completely correspond to the bronchial opening of the right upper lobe. Even if the alignment is good during anesthesia and intubation, after the operation begins, the operator’s stretching of the left lung will cause the carina and the movement of the right main bronchus, resulting in the deviation of the vent hole of the right upper lobe and the opening of the bronchus of the right upper lobe , even with a small deviation, eventually leading to right upper lobe ventilation obstruction, the anesthetist had to repeatedly adjust the position of the ...

AI Technical Summary

Problems solved by technology

[0003] The purpose of the present invention is to provide a right double-lumen bronchial intubation, which solves the current situation that the right double-lumen bronchial intubation is difficult to align, solves the damage caused by repeated tube adjustments during the operation, and relieves the pain of the right single lung. The resistance during ventilation also reduces the workload of the anesthetist
