Abstract

Exemplary embodiments of the present disclosure provide reusable training automatic injection training devices, and components thereof, to simulate and/or mimic an operation of an actual automatic injection device. Exemplary embodiments of the training device can provide audible instructions, which can be in different languages, output from circuitry associated with the training device. Exemplary embodiment of the training device can be a self-contained and portable device that mimics a shape, size, and function of an actual automatic injection device without including a needle or any drug on board. Exemplary embodiments can be implemented to train a user on an operation and/or usage of an actual automatic injection device using embodiments of the automatic injection training devices so that a user can practice an autoinjection without injecting a therapeutic agent, such as a liquid drug, into a recipient.
