Patent attributes
The present invention relates to an automatic injection training device comprising an elongated housing having a distal end and an opposite proximal end and extending along a longitudinally axis (L); a tubular demo container axially and rotationally fixed relative to the elongated housing and having a tubular wall extending along the longitudinally axis (L); a reloadable plunger assembly comprising a plunger rod which is movable in the demo container between a first and a second position and a first energy accumulating element configured to move the plunger rod from the first to the second position; an actuation assembly configured to hold the plunger rod in the first position and to release the plunger rod from the first position. The invention is characterized in that the device further comprises a first signal generating element releasably connected to the plunger rod and a second signal generating element fixedly connected to the plunger rod, and wherein each signal generating element is configured to interact independently from each other for generating audible feedback signals.
