1. A wearable drug delivery device comprising:
a housing;
a container disposed in the housing;
an insertion mechanism disposed in the housing;
a fluid pathway connector configured to provide a fluid flowpath between the container and the insertion mechanism; and
the insertion mechanism including
a proximal end and a distal end,
a trocar or hollow delivery needle,
a hub coupled to the trocar or hollow delivery needle, the hub being movable relative to the housing between a first hub position adjacent to the proximal end of the insertion mechanism and a second hub position adjacent to the distal end of the insertion mechanism,
a power source configured to generate rotational motion, and
a motion conversion mechanism operatively connecting the power source and the hub, and configured to convert the rotational motion of the power source into linear motion of the hub,
wherein the motion conversion mechanism includes a pin and a yoke, the pin being slidably received in a slot formed in the yoke,
wherein operation of the power source causes at least a portion of the motion conversion mechanism including the yoke to move with respect to the housing.
