Aspirator

A device that uses suction or air pressure to remove fluid, gas, or particles from a space, commonly used in medical procedures and laboratories.

From Latin 'aspirare' (to breathe upon) + '-or' (agent noun suffix). The root 'ad-' (to) + 'spirare' (to breathe) originally meant 'to breathe toward,' then evolved to mean 'to aspire to' and eventually to describe mechanical devices that draw in air or liquids.
