Background technology
When lesion occurs for the left pulmonary of patient or right lung, needs to keep apart left pulmonary and right lung, make a left side
Side lung and right lung are separately ventilated, and Ipsilateral Lung infection is avoided to be good for side lung.During treatment, it is also necessary to which the lung of both sides leads to simultaneously
The pulmonary ventilation of gas or only side.In order to reach these purposes, need to use tracheal catheter.
For common tracheal catheter mainly by three kinds, the first is single-lumen bronchial tube, has air bag on single-lumen bronchial tube,
Single-lumen bronchial tube is inserted into the main bronchus of unilateral lung, the gas outlet of single-lumen bronchial tube is made to be placed in the main bronchus of unilateral lung
In, by airbag aeration, the main bronchus of air-pocket obstruction unilateral lung in this way can keep apart the lung of both sides and can be to being inserted into single-chamber
The unilateral lung of tracheal catheter is ventilated, but when needing to be switched to double pulmonary ventilation, needs to be intubated again to patient, operation fiber crops
It is tired, also patient can be made very painful, and cross-infection is easy to happen during plug.Second is double-lumen catheter,
There are two cavities for tool on double-lumen catheter, correspond to left lung and right lung respectively, also have air bag on double-lumen catheter, work as gas
Capsule can keep apart left lung and right lung when inflating, but two-chamber tracheae has the following disadvantages：Catheter outer diameter is thicker, in tracheae
It is easy to damage respiratory tract when intubation, is not suitable for the thinner patient of tracheae and uses；The unilateral intracavitary diameter of double lumen tube is smaller, is unfavorable for
Ventilation, is easy to happen gas duct high pressure.The third is single-lumen bronchial tube combination bronchial occlusive device, and when operation, bronchus is sealed
Stifled device is inserted into the main bronchus of unilateral lung, the airbag aeration on bronchial occlusive device can be realized to the isolation of both sides lung, still
The catheter diameter of bronchial occlusive device is thinner, it is difficult to install suction pipe in the conduit of bronchial occlusive device the secretion of lung is sucked out
