1. An injection training device comprising:
a barrel;
a first assembly including a plunger and a damper housing coupled to the plunger, wherein the first assembly is translatable with respect to the barrel; and
a second assembly including a rotor, such that a damper chamber is defined between the rotor and the damper housing, wherein a viscous fluid is disposed in the damper chamber,
wherein translation of the first assembly causes a force to be applied to the rotor that causes the rotor to rotate about an axis of rotation with respect to the damper housing, and the viscous fluid resists rotation of the rotor about the axis with respect to the damper housing.
