cannula

A tube inserted into the body to drain or inject fluid.

Two or three cannulæ are requisite also for washing out the sinuses.

The cannula had come askew in his nose and he pushed it straight, his hand moving slowly, like the hand of a man who is dreaming with his eyes open.

A hose or tube that connects directly from an oxygen bottle or other source to the user's nose, commonly used by aircraft pilots or others needing direct oxygen breathing apparatus.
