Autoinjector

Autoinjectors were an important medical technology, starting their life during the time of the Great Patriotic War, they went through a couple hundred changes until the 2090s, when humanity fell. The most advanced type that proliferated the world by that point, was a third-generation smart injector, which had a microcomputer system that could instantly detect the condition of the person it was being used on, and administer the correct dosages of any number of the several medicines it had contained in it.
