1. An injection device trainer for training a user to use an injection device, the injection device trainer comprising:
a body portion;
an actuator positioned towards a proximal end of the body portion, the actuator moveable from a proximal position to a distal position;
a shield positioned towards a distal end of the body portion, the shield moveable between: an initial position; a retracted position that is more proximal relative to the body portion than the initial position; and an extended position that is more distal relative to the body portion than the initial position; and
a locking member adapted to be rotatable between a first orientation in which the locking member resists movement of the actuator from the proximal position to the distal position; and a second orientation in which the locking member permits the actuator to move from the proximal position to the distal position;
wherein the first orientation of the locking member is configured to hold the shield in the initial position such that the shield is prevented from moving from the initial position to the extended position, and permits movement of the shield from the initial position to the retracted position;
wherein the shield is configured to contact with the locking member when moving from the initial position to the retracted position in order to move the locking member from the first orientation to the second orientation; and
wherein movement of the actuator by a first distance towards the distal position is configured to unlock the shield from the locking member such that the shield is allowed to move towards the extended position.
 
32. A method of using an injection device trainer, the injection device trainer comprising:
a body portion;
an actuator positioned towards a proximal end of the body portion, the actuator moveable from a proximal position to a distal position;
a shield positioned towards a distal end of the body portion, the shield moveable between: an initial position; a retracted position that is more proximal relative to the body portion than the initial position; and an extended position that is more distal relative to the body portion than the initial position; and
a locking member rotatable between a first orientation in which the locking member resists movement of the actuator from the proximal position to the distal position; and a second orientation in which the locking member permits the actuator to move from the proximal position to the distal position;
wherein the first orientation of the locking member is configured to hold the shield in the initial position such that the shield is prevented from moving from the initial position to the extended position, and permits movement of the shield from the initial position to the retracted position; and
wherein the method comprises:
moving the shield from the initial position to the retracted position so that the shield contacts with the locking member in order to move the locking member from the first orientation to the second orientation; and
moving the actuator by a first distance towards the distal position to unlock the shield from the locking member such that the shield moves towards the extended position.
 
34. An injection device trainer for training a user to use an injection device, the injection device trainer comprising:
a body portion;
an actuator positioned towards a proximal end of the body portion, the actuator configured to be gripped by a user to move the actuator from a proximal position to a distal position, wherein the actuator is coupled with a rotor, such that movement of the actuator from the proximal position to the distal position causes the rotor to rotate; and
a damping element coupled to or coupleable to the rotor in order to damp the rotation of the rotor and thereby damp movement of the actuator towards the distal position; and
a shield positioned towards a distal end of the body portion, the shield moveable relative to the body portion between an initial position, and a retracted position that is more proximal relative to the body portion than the initial position.
 
38. A method of using an injection device trainer, the method comprising:
a user gripping an actuator of the injection device trainer, the actuator positioned towards a proximal end of a body portion of the injection device trainer; and
a user pushing on the actuator to move the actuator relative to the body portion from a proximal position to a distal position such that movement of the actuator from the proximal position to the distal position causes 1) a rotor of the injection device trainer to rotate and 2) a damping element of the injection device trainer to damp rotation of the rotor, thereby damping movement of the actuator towards the distal position,
wherein the method comprises, prior to moving the actuator, moving a shield of the injection device trainer that is positioned towards a distal end of the body portion such that the shield moves between an initial position, and a retracted position that is more proximal relative to the body portion than the initial position.
