Double-lumen endobronchial tube capable of realizing rapid collapse of lung of operation side

Abstract

The invention provides a double-lumen endobronchial tube capable of realizing rapid collapse of a lung of an operation side, and belongs to the technical field of medical equipment. The double-lumen endobronchial tube comprises a double-lumen connecting pipe, a double-lumen ventilation switching pipe and a double-lumen ventilation pipe, one end of the double-lumen ventilation switching pipe is detachably connected to the double-lumen connecting pipe, the other end of the double-lumen ventilation switching pipe is detachably connected to the double-lumen ventilation pipe, a first exhaust guidepipe and a second exhaust guide pipe are installed on one ventilation pipe of the double-lumen ventilation switching pipe, and lumens of the first exhaust guide pipe and the second exhaust guide pipeare communicated to lumens of the ventilation pipe connected to the first exhaust guide pipe and the second exhaust guide pipe, respectively. According to the invention, the rapid and good collapse ofthe lung of the operation side can be realized, so that a good operative field of vision and operation space are provided for thoracic surgery, especially for thoracoscopic surgery, and meanwhile, single-lung ventilation or double-lung ventilation can be conveniently switched in the operation process by the double-lumen endobronchial tube cooperated with operation.

Description

technical field [0001] The invention belongs to the technical field of medical devices, and in particular relates to a double-lumen bronchial catheter for realizing rapid collapse of the operated side lung. Background technique [0002] At present, in thoracic surgery, especially in thoracoscopic surgery, which is more and more widely carried out, surgeons need to quickly and well collapse the operative side lung after the operation begins, so as to free the lung, esophagus, and mediastinum in the thoracic cavity , resection and other operations, sometimes it is necessary to rapidly expand and then quickly collapse the operated lung to varying degrees during the operation. At present, the usual method for lung collapse is to separate the air intake tube of the operated side lung from the anesthesia machine and expose it to the air, so that the operated side lung will slowly discharge air, and the exhaust speed is relatively slow. It is necessary to use additional clamps to s...

Problems solved by technology

At present, the usual method for lung collapse is to separate the air intake tube of the operated side lung from the anesthesia machine and expose it to the air, so that the operated side lung will slowly discharge air, and the exhaust speed is relatively slow. It is necessary to use additional clamps to seal the pipeline, and it cannot Rule out the possibility of air rebreathing into the lungs
