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.

Claims

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.

2. The drug delivery system of claim 1, wherein the needle further comprises a needle point at an opposing end of the needle from the needle tip, the needle point positioned stationary within the housing, and the cartridge comprises a seal for sealing the drug therein, wherein an initial movement of said plunger by said power actuator impels the cartridge and drives said seal against said stationary hollow needle, to, in turn, penetrate said needle through said seal, and subsequent movement of said plunger discharges the drug from cartridge and through the needle toward the needle tip.

3. The drug delivery system of claim 1, wherein the needle septum is positioned within the needle opening.

4. The drug delivery system of claim 1, wherein the needle tip is oriented substantially perpendicular to the base plane.

5. The drug delivery system of claim 1, wherein the needle tip is injected into the subject'"'"'s skin in the released position.

6. The drug delivery system of claim 1, wherein the needle is biased by a biasing member from the retracted position to the released position, and wherein the delivery system further comprises an arrestor impeding movement of the needle from the retracted position to the released position, the arrestor being retractable to permit release of the needle into the released position.

7. The drug delivery system of claim 6, further comprising a rotatable shaft and a motor operatively connected to the rotatable shaft for rotating the shaft, the rotatable shaft being threadedly attached to the arrester, wherein rotation of the shaft retracts the arrestor from impeding movement of the needle.
