External bronchial blanking plug and tracheal catheter

Abstract

The invention discloses an external bronchial blanking plug and a tracheal catheter. The external bronchial blanking plug comprises a bronchus blanking plug body and a blocking catheter connecting mechanism. The blocking catheter connecting mechanism can temporarily lock the position of the rear section of the bronchus blanking plug, the blocking catheter connecting mechanism is loosened, the tailof the bronchus blanking plug can be operated, and the bronchus blanking plug can independently advance or retreat or rotate. The blockage catheter connecting mechanism can temporarily lock the correctly assembled tracheal catheter, and can be operated to be separated from the tracheal catheter by loosening the catheter connecting mechanism. According to the external bronchus blanking plug and the tracheal catheter, the space in the trachea of a patient can be fully utilized, the occupation of the bronchus blanking plug on the ventilation cavity of the tracheal catheter is reduced, the airwaypressure of single-lung ventilation is reduced, and single-lung ventilation can be safely implemented in a patient with a small airway; during single-lung ventilation, a video endoscope can be conveniently placed into the ventilation cavity of the tracheal catheter through the tracheal catheter to implement airway observation and diagnosis, a patient with poor lung function pulls out the bronchial plug after an operation, the tracheal catheter is reserved, and mechanical assisted respiration can be continuously implemented.

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
