Description
Technical Field
The invention relates to the technical field of medical instruments, in particular to a disposable single-cavity bronchial catheter.
Background
The patient of lung operation increases year by year, the airway of human body, more than the carina, is the main airway, with a trachea, below the carina divide into left and right main bronchus, and then divide into two lungs, two lobes on the left, three lobes on the right, the left main bronchus is slender relative to the right main bronchus, the right main bronchus is relatively short and thick, the opening is higher than the left side, the lung operation needs to separate the two lungs in the art, make one side lung ventilate and ensure the oxygen supply, the lung of operation side collapses, facilitate the operation, therefore must use the special tool to realize the intraoperative single lung ventilation, the common tool that realizes the single lung ventilation of lung operation at present is disposable double-chamber bronchial catheter and disposable bronchial stopper, no matter which method, the anesthesia doctor can use the fiber bronchoscope or electron scope, etc. to ensure the position of the catheter is correct, the mirror should enter the tracheal catheter, so must require the internal diameter of the tracheal catheter, double lumen bronchial catheters No. 32 and below cannot be positioned using a fiberoptic bronchoscope or an electronic scope.
The existing double-lumen bronchial catheter has large outer diameter, large hardness and large damage to the airway of a patient, and because the double-lumen bronchial catheter is divided into double lumens, the passage reserved for a fiberoptic bronchoscope or an electronic endoscope is very small, for the patient with a small airway, the double-lumen bronchial catheter is adopted, the position of the tracheal catheter cannot be judged easily because the bronchoscope cannot enter the double-lumen bronchial catheter due to selection of a catheter smaller than 32, the operation anesthesia is difficult, the sputum suction operation is not convenient for a narrow lumen, in addition, the plugging device needs to firstly carry out common tracheal intubation (7.5 # or 8.0# catheter), then is arranged into the double-lumen bronchial catheter to plug the main tracheal catheter at one side, the operation steps are multiple, and the plugging device cannot meet the operation requirements when the patient with the short and small right main tracheal catheter frequently happens, and the patient also has branches in the main airway, the plugging device cannot meet the operation requirements, and the double-lumen bronchial catheter has to be, and the plugging device adopts the cuff to plug the main bronchus, so the main bronchus is easy to be damaged during operations such as sputum suction, the air leakage is easy due to insufficient inflation, the risk of damage is caused due to too much inflation, the ventilation of a single lung and the ventilation of two lungs are often required to be switched in the operation, and the air suction and inflation are not very convenient. To this end, we propose a single-use single-lumen bronchial catheter.
