One-lung ventilation management catheter

Abstract

The invention discloses a one-lung ventilation management catheter. The catheter comprises a ventilation main pipe, a plugging auxiliary pipe and a double-pipe connecting mechanism, wherein a rear section of the plugging auxiliary pipe is connected with a rear section of the ventilation main pipe through the double-pipe connecting mechanism, the plugging auxiliary pipe has an outer diameter less than 5 mm and is arranged outside a ventilation cavity of the ventilation main pipe, and the length of the plugging auxiliary pipe is larger than that of the ventilation main pipe; the double-pipe connecting mechanism can temporarily lock positions of the rear section of the ventilation main pipe and the rear section of the plugging auxiliary pipe, so that the plugging auxiliary pipe can rotate around the ventilation main pipe outside the ventilation cavity of the ventilation main pipe along with rotation of the ventilation main pipe; and when the double-pipe connecting mechanism is loosened, atail part of the plugging auxiliary pipe can be operated, so that the plugging auxiliary pipe independently rotates, advances or retreats or is separated from the ventilation main pipe. According tothe one-lung ventilation management catheter, an airway pressure can be reduced to the maximum extent during one-lung ventilation, one-lung ventilation can be implemented in children, tracheal catheter replacement operation can be avoided, and the one-lung ventilation management catheter is simple in structure and wide in applicability.

Description

technical field [0001] The invention relates to the technical field of medical equipment, in particular to a catheter for one-lung ventilation management. 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. However...

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
