Trachea cannula double-channel connector

The utility model relates to a trachea cannula double-channel connector. The trachea cannula double-channel connector comprises an outer cannula base; one end of the cylinder is closed, and the other end is open; the open end of the barrel is rotationally connected to the outer sleeve base, and a working space is formed by the open end of the barrel and the outer sleeve base; an atomizing pipe and a sputum collecting pipe which extend into the working space are arranged on the periphery of the cylinder body; the inner tracheal cannula is arranged on the side, away from the barrel, of the outer cannula base and extends into the working space, and the atomization tube and the sputum collecting tube are alternatively connected with the inner tracheal cannula in an abutting mode and communicated with the inner tracheal cannula. When atomization is needed, the barrel body is rotated to enable the atomization pipe to abut against and communicate with the trachea inner sleeve; when sputum needs to be collected, the
