Abstract
Embodiments provided herein include a resettable injection training device having a body, a plunger slidable relative thereto, an injection simulation member and retractable and extendable shield, wherein the shield releasably locks in a retracted position prior to use. After use of the training device, the shield extends over the injection simulation member to prevent contact with the injection simulation member. Resetting of the slidable shield occurs by applying a force onto a distal end of the shield to retract the shield until a shield locking surface interacts with a locking surface on the body to maintain the shield in a retracted position. Release of the shield from a retracted position to an extended position may occur by moving the plunger toward a distal end of the body until a contact region at a proximal end of the plunger releases the shield locking surface from the body locking surface to release the shield.
