ENGAGEMENT AND SENSING SYSTEMS AND METHODS

摘要

A delivery device for delivering fluidic media may include a second housing portion configured to be selectively engaged with and disengaged from a first housing portion adapted to be carried by a user, a drive device configured to be operatively engagable with a plunger arm connected to a plunger head arranged for movement in an axial direction of a reservoir supported by one of the first and second housing portion to drive fluidic media from the reservoir, a drive linkage for operatively engaging the drive device with the plunger arm for allowing the drive device to move the plunger arm, the drive device including a first gear engageable with the plunger arm and a second gear configured for lateral movement to allow the second gear to engage the plunger arm.
