Abstract
In an embodiment, an injection simulation device is provided including a housing defining a channel, the housing comprising a proximal end and a distal end, a plunger comprising a plunger rod body having a proximal end and a distal end and a stopper disposed at the distal end of the plunger rod, the plunger movable proximally and distally within the channel; and a friction feature associated with the housing, the friction feature for interfacing with the plunger rod, wherein the plunger moves in a distal direction relative to the housing to simulate medicament delivery and in a proximal direction to reset the injection simulation device, wherein the friction feature optionally causes differential resistance on the plunger rod, when the plunger rod moves in either the distal or proximal direction.
