Abstract: An automatic injector training device comprises an outer structure having i) a rearward end, ii) a forward end arranged to be engaged with an injection site of the user, and iii) an intermediate portion. A manually movable actuating member is movable between a storage position and an activated position by being manually depressed by the user. A prod member is movable within the outer structure between a retracted position and an outwardly extending position when the actuating member is manually moved between the storage position to the activated position. A spring member is disposed within the outer structure and arranged so as to move the prod member from the outwardly extending position to the retracted position when the actuating member is moved from the activated position to the storage position.
