MOTION ACTIVATED SEPTUM PUNCTURING DRUG DELIVERY DEVICE
First Claim
1. A wearable drug delivery apparatus for administering a drug to a recipient, the drug delivery system comprising:
- a housing having a base surface configured to be positioned proximate the subject'"'"'s skin, the base surface defining a base plane having a needle opening therein;
a controlled rate power actuator;
a cartridge containing the drug therein positioned within the housing, having a longitudinal axis being substantially parallel to the base plane;
a plunger movably mounted in the cartridge, the plunger being movable by the power actuator along the longitudinal axis;
a needle fluidly connectable to the cartridge and having a needle tip including a distal opening, the needle tip being movable between a retracted position, wherein the needle tip is located within the housing, and a released position, wherein the needle tip extends through the needle opening and is located outside of the housing; and
a needle septum positioned in the housing;
wherein the needle tip is inserted in the needle septum, sealing the distal opening, in the retracted position, and the needle tip penetrates through the needle septum in the released position.

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.
