Description

Technical Field

[0001] The utility model relates to an integrated bronchial blocking catheter, belonging to the technical field of medical equipment. Background Art

[0002] Bronchial blocking catheters are often used for single-lung ventilation and single-lung isolation during thoracotomy. Currently commonly used bronchial blocking catheters usually include a blocking tube four-way joint, a tracheal tube, and a bronchial tube. The various components in the finished product are split and need to be assembled on site. During assembly, the outer wall of the bronchial tube needs to be lubricated and inserted into the tracheal tube. After the bronchial tube is inserted into the tracheal tube, a portion of space is reserved between the outer wall of the bronchial tube and the inner wall of the tracheal tube for inserting a bronchoscope, a drainage tube, and a suction tube when needed during surgery. Since tracheal tubes and bronchial tubes usually have a certain degree of softness, this results in the bronchial tube not being able to be placed close to one side of the inner wall of the tracheal tube when inserted into the tracheal tube, making it difficult to insert or taking more time to insert a bronchoscope, a drainage tube, a suction tube, and other treatment devices during surgery, thereby affecting the progress of the operation and reducing the efficiency of the operation.
