An external bronchial occluder and endotracheal tube

Abstract

The invention discloses an external bronchial occluder and a tracheal catheter, comprising a bronchial occluder and a connecting mechanism for the occluded catheter. The blocking catheter connecting mechanism can temporarily lock the position of the rear section of the bronchial occluder, loosen the blocking catheter connecting mechanism, and can manipulate the tail of the bronchial occluding device to make the bronchial occluding device advance, retreat or rotate independently. The blocked catheter attachment mechanism temporarily locks a properly assembled endotracheal tube, releases the blocked catheter attachment mechanism, and maneuvers the blocked catheter attachment mechanism away from said endotracheal tube. The external bronchial occluder and tracheal catheter provided by the present invention can make full use of the space in the patient's trachea, reduce the occupancy of the bronchial occluder on the ventilation cavity of the tracheal catheter, reduce the airway pressure of one-lung ventilation, and can be used in patients with small airways. Safe implementation of one-lung ventilation. During one-lung ventilation, it is convenient to place a video endoscope through the tracheal tube ventilation cavity for airway observation and diagnosis. For patients with poor lung function, the bronchial blocker is removed after the operation, and the tracheal tube is retained, so that mechanical ventilation can continue. Assisted breathing.

Description

technical field [0001] The invention relates to the technical field of medical equipment, in particular to an external bronchial occluder and a tracheal tube. Background technique [0002] One-lung ventilation management catheters are widely used in anesthesia for thoracic surgery. Its function is to isolate the left and right lungs and achieve separate ventilation of the left and right lungs. Current single-lung ventilation management catheters include double-lumen bronchial catheters and bronchial occluders. The existing devices of these products can meet the clinical needs in adults with normal lung function, but obviously cannot meet the clinical needs in children with poor lung function. [0003] Although a double-lumen bronchial catheter can safely and effectively implement left or right lung ventilation to provide conditions for left or right chest and lung surgery, it can also facilitate the removal of sputum from the left and right side bronchi during surgery.

Problems solved by technology

However, when the bronchial occluder is used, it must be placed in the lumen of the single-lumen endotracheal tube, which occupies the lumen of the single-lumen endotracheal tube. When the sputum needs to be cleaned, it will cause great interference to the insertion of the suction tube, which is not conducive to the suction operation.

If you want to accurately suck sputum, you must complete it with the assistance of video endoscope. At this time, the single-lumen endotracheal tube lumen is inserted with bronchial occluder, suction tube and video endoscope at the same time, which is very difficult to operate.

At the same time, during pediatric surgery, the lumen of the single-lumen endotracheal tube itself is relatively thin, so it is very difficult to insert a bronchial occluder. Inability to perform effective ventilation
