Injector training device

A training device for simulating an injection procedure experience when using a real-life fully functional auto-injection device containing a pre-filled container of medicament, the training device comprising,

• an elongate outer housing having an inner surface, a proximal end and a distal end, the outer housing containing,
• a demo container axially and rotationally fixed relative to the outer housing;
• a plunger assembly having a non-rotating plunger, where a distal portion of the plunger is slidable within the demo container;
• a coiled spring having a distal end fixed axially relative to the outer housing and a proximal end attached to the plunger assembly such that the coiled spring is in an extended partially uncoiled tensed configuration when the plunger assembly is in a cocked position;
• a rotary damper gear assembly attached to a proximal end of the plunger assembly and having a gear rotatably engaged with a rack axially fixed to the inner surface of the outer housing;
• and
• a rotatable lock having a first position where the lock is engaged directly with the plunger to prevent the plunger from moving axially and a second position where the lock is disengaged from the plunger to allow the plunger to move axially relative to the lock and outer housing.
