Auto-injectors are pre-filled, single-use, self-contained drug delivery systems that allow the user to self-administer precise dosages of injectable medication quickly and easily, without the apprehension normally associated with a traditional syringe. BoundTree Medical offers Meridian Auto-Injectors and Auto-Injector Training Simulators for domestic preparedness applications. Each training device is the same size as the auto-injector it simulates, works in the same manner and can be reset after activation and used again. The trainers contain no medication or needle.
