Motion activated septum puncturing drug delivery device

An apparatus wearable by a recipient having a single motion power train for sequentially unsealing a reservoir and delivering a drug to the recipient, comprising:

• a) a seal of the reservoir;
• b) a controlled rate power actuator;
• c) a piston of the reservoir and a plunger assembly directly engaging the piston and driven by said controlled rate power actuator, and
• d) a surface of the apparatus configured for attaching to a skin of the recipient;
• e) a needle positioned stationary with respect to said surface and partially inserted into the seal for a predetermined period of time prior to delivering the drug;
• and
• f) a pathway substantially parallel to said surface for movement of the reservoir,
• wherein an initial movement of said plunger assembly by said power actuator, after the predetermined period of time, translates the piston to advance the sealed reservoir along said pathway and drives said seal against said stationary hollow needle, to, in turn, fully penetrate said hollow needle through said seal, and subsequent movement of said plunger assembly translates the piston through the unsealed reservoir, to, in turn, discharge the drug from the reservoir.
