A device designed to be used by a layperson (this usually being the recipient of the injection) to reset the loaded position of an injector in a safe and controlled manner. It will typically be designed like a small box or container and have a hinged lid. The injector is placed inside this device and when the lid is closed an internal mechanism resets the injector to its firing position. The injector is removed from this device, the medication is inserted (typically a prefilled syringe or cartridge) and it is ready for use by the user. This is a reusable device.
