First Claim
1. A delivery device for delivering fluidic media, the delivery device comprising:
- a first housing portion adapted to be secured to a user;
a second housing portion configured to be selectively engaged with and disengaged from the first housing portion, one of the first housing portion and the second housing portion for supporting a reservoir for containing fluidic media;
a drive device configured to be operatively engageable with a plunger arm connected to a plunger head arranged for movement by the drive device in an axial direction of the reservoir, the drive device configured to drive fluidic media from the reservoir in a case where the drive device is operatively engaged with the reservoir and the plunger arm is moved in the axial direction relative to the reservoir; and
a drive linkage for operatively engaging the drive device with the plunger arm to allow the drive device to move the plunger arm, the drive linkage including a first gear and a second gear operatively engaged with each other, the first gear engageable with the plunger arm, the second gear configured for lateral movement such that the lateral movement of the first gear allows the second gear to engage the plunger arm.
