Etymology: "Autoinjectors" is the plural of "autoinjector," a compound of the prefix "auto-," from Greek "autos" meaning "self," and "injector," a device for forcing a fluid into something, from Latin "iniectare," to throw into. Together the parts describe a tool that delivers an injection by itself, without the user having to press a plunger through a syringe by hand. The plural form simply reflects that the noun is countable: a pharmacy or emergency kit may contain several units, each one a single-use spring-loaded or pre-filled pen-like device. The compound is a transparent, modern technical formation, built from familiar classical parts to name a mechanism rather than an older everyday object.

Synonyms: auto-injectors, self-injectors, automatic injectors, pen injectors, epinephrine injectors
