An air line adapter structure includes a connecting tube body and an air adapter. The connecting tube body includes an air tube connector, a breathing connector interconnected with the air tube connector and a suction connector interconnected with the air tube connector and the breathing connector. The air adapter includes a sheathing bushing and a connecting tube extended outward from a sheathed bushing, and the interior of the sheathing bushing is interconnected with the interior of the connecting tube and sheathed onto the breathing connector of the connecting tube body. The external circumference of the connecting tube is smaller than the external circumference of the sheathing bushing, such that the connecting tube can be connected directly to an oxygen tube for timely supplying oxygen to patients and greatly broadening the scope of application of the suction apparatus. |
