Abstract
A resettable injection training device embodiment is provided. In one embodiment, the device may include an outer housing comprising locking tabs at its proximal end, a safety shield, the safety shield being slidable relative to the outer housing between a ready-to-fire position, and a fired position, wherein when the safety shield is in a fired position, the injection simulation member is retracted into the outer housing. The device may further include a plunger comprising a proximal end and a distal end, the proximal end comprising a plunger contact portion for interfacing with the locking tabs to displace the locking tabs to unlock the safety shield, and a biasing member disposed between the outer housing and the safety shield to extend the shield in a proximal direction upon release of the locking tabs, wherein retraction of the plunger and proximal movement of the outer housing resets the device.
