Medical double-layer trachea cannula

Abstract

The invention discloses a medical double-layer trachea cannula. The medical double-layer trachea cannula comprises a main trachea cannula, a second trachea cannula and an air bag assembly. The secondtracheal cannula comprises a first bronchial cannula and a second bronchial cannula, and the first bronchial cannula and the second bronchial cannula are accommodated in the main tracheal cannula sideby side; the air bag assembly comprises a first air bag, a second air bag and a third air bag, and the first air bag sleeves the main trachea cannula; the second air bag is sleeved on the first bronchial cannula; the second bronchial cannula is sleeved with the third air bag. The air bag is used for sealing a gap between the cannula and a trachea or a bronchus. Oxygen is provided for the left lung lobe and the right lung lobe through the first bronchial cannula and the second bronchial cannula which are contained in the main tracheal cannula respectively, and the situation that the tracheal cannula cannot supply oxygen effectively when the lung lobe on one side has mechanical injury or generates lesion and cannot receive oxygen or oxygen supply to the lung on one side is needed and lung treatment on the other side is needed is avoided, and the risk of treatment is reduced.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a medical double-layer tracheal intubation tube. Background technique [0002] When the patient has difficulty breathing or cannot breathe spontaneously, an endotracheal tube is needed to help the patient breathe. The existing endotracheal tube is connected to the patient's lungs through the airway. [0003] The current tracheal intubation has the following problems during use: the two lungs cannot be operated independently, and the ventilation of both lungs must be suspended simultaneously when suctioning sputum is required; when there is sputum or bleeding in one lung, the blood or sputum will pass through the tube Into the other lung, resulting in bilateral lung lesions; when one lung is not suitable for pressure ventilation, the differential ventilation of the two lungs cannot be guaranteed; when one lung is hemorrhage and other diseases, ventilation cannot be perform...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to provide a medical double-layer tracheal intubation to solve the problem that the existing tracheal intubation in the prior art cannot effectively send oxygen to the other lung lobe, resulting in increased treatment risks
