MOTION ACTIVATED SEPTUM PUNCTURING DRUG DELIVERY DEVICE
First Claim
1. A drug delivery device for delivering a drug to a recipient comprising:
- a housing including therein;
a mechanical drive train, a reservoir containing said drug, a seal sealing an opening in the reservoir, a hollow needle for puncturing through the seal and unsealing the reservoir, and a plunger movably positioned in the reservoir,wherein, an initial movement of the drive train drives one of the hollow needle and the seal toward the other of the hollow needle and the seal, to, in turn, penetrate through the seal with the hollow needle and unseal the reservoir, and subsequent movement of the drive train advances the plunger through the reservoir, to, in turn, discharge the drug from the reservoir, andthe housing further includes a base for attachment to the recipient, an opening for accessing the reservoir, a door movable between a closed position, at least partially blocking said opening, and an open position, unblocking said opening, and a locking mechanism for locking the door in the closed position, wherein the locking mechanism is activated by the initial movement of the drive train.

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.

9. A method for delivering a drug to a recipient via a drug delivery device, the drug delivery device including a housing including therein a mechanical drive train, a reservoir containing said drug, a seal for sealing the reservoir, a hollow needle, and a plunger, the housing further including a base, an opening for accessing the reservoir, a door, and a locking mechanism, the method comprising:
-
attaching the base to the recipient; moving the door into a closed position, at least partially blocking the opening; initially driving the mechanical drive train, and, in turn, activating the locking mechanism to lock the door in the closed position and driving one of the hollow needle and the seal toward the other of the hollow needle and the seal, and, in turn, penetrating through the seal with the hollow needle to unseal the reservoir, and further driving the mechanical drive train to advance the plunger through the reservoir, and, in turn, discharge the drug from the reservoir. - View Dependent Claims (10, 11, 12, 13, 14, 15, 16, 17)
