Double-cannula bronchial intubation

Abstract

The invention discloses a double-cannula bronchial intubation. The double-cannula bronchial intubation comprises an outer intubation and an inner intubation glidingly sleeving the inside of the outerintubation, wherein a first inflation airbag is arranged outside the front end of the outer intubation and is connected with a first inflation assembly, and a second inflation airbag is arranged outside the front end of the inner intubation and is connected with a second inflation assembly. The inner intubation of the double-cannula bronchial intubation can stretch to bronchi and can be nasally inserted into a bronchus on any side, so that a long-term one-lung ventilation purpose is achieved. Besides, if one-lung ventilation is not required, an inner cannula can be retracted back to main airway, and the inflation does not need to be replaced. Besides, the double-cannula bronchial intubation can stretch to the bronchi and can be advantageously used by a patient requiring long-term one-lungventilation. Furthermore, a detachable segment can be separated from the inner intubation, can be remained to be used as a stent in the airway, is placed at an exact position and can be advantageouslytaken out, thereby achieving treatment on bronchopleural fistula and airway softening and stenosis.

Description

technical field [0001] The invention relates to the field of medical instruments, in particular to a double-tube bronchial intubation tube. Background technique [0002] The current common tracheal intubation can only be inserted through the nose above the tracheal carina, and cannot be inserted into one side of the bronchi. However, some special diseases often require one-lung ventilation, such as bronchopleural fistula. Therefore, it is necessary to accurately insert the endotracheal tube into one side of the bronchus and keep the tube on for a long time. Although the current double-lumen endobronchial tube can be accurately carried out One-lung ventilation, but it can only be inserted through the mouth, the diameter of the tube is relatively thick, and it cannot tolerate long-term intubation. We need a new type of bronchial intubation that can be inserted through the nose and can withstand long-term intubation. The current common tracheal intubation And double-lumen bron...

Therefore, it is necessary to accurately insert the endotracheal tube into one side of the bronchus and keep the tube on for a long time. Although the current double-lumen endotracheal intubation can be performed accurately One-lung ventilation, but it can only be inserted through the mouth, the diameter of the tube is relatively thick, and it cannot tolerate long-term intubation. We need a new type of bronchial intubation that can be inserted through the nose and can withstand long-term intubation. The current common tracheal intubation and double lumen bronchial intubation cannot solve the above problems
