Motion activated septum puncturing drug delivery device
First Claim
1. 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, andd) 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.

Abstract
A method and apparatus are disclosed for delivery of a drug to a recipient. In some embodiments, the delivery apparatus may unseal a drug containing reservoir. In some embodiments, the delivery rate may be controlled and/or adjustable. Optionally the apparatus may be disposable. Optionally, the apparatus may have a low profile and/or be wearable and/or attachable to the recipient. Optionally, discharge of the drug and/or unsealing of the reservoir may be driven by a plunger moving parallel to the base of the apparatus. Optionally, the apparatus may release a hypodermic needle into the recipient. Optionally, release of the hypodermic needle may be in a direction non-parallel and/or orthogonal to the direction of movement of the plunger. Optionally, prior to release, the hypodermic needle may be preserved in an aseptic state by a needle opening septum sealing a needle opening. Optionally, upon release, the hypodermic needle may pierce the needle opening septum.
