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 engagable 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 supported on a shaft having an axis and a longitudinal dimension, the second gear supported for rotation about the axis of the shaft, the second gear supported for lateral movement in a direction along the longitudinal dimension of the shaft such that the lateral movement of the second gear allows the first gear to engage the plunger arm.
