Drug Delivery Device
First Claim
1. A drug delivery device comprising:
- a disposable housing having an interior surface defining an interior space, and an exterior surface;
a needle having a retracted state wherein the needle is withdrawn inside of the interior space and a deployed state wherein a pointed end of the needle projects beyond the exterior surface of the housing;
an injector coupled to the needle to move the needle between the retracted and deployed states;
a reservoir disposed within the interior space, the reservoir configured to receive a volume of a drug and to be in fluid communication with the needle; and
a controller coupled to the injector and the reservoir, the controller being configured to actuate the injector to move the needle from the retracted state to the deployed state only once, and to actuate the reservoir to deliver the volume of the drug to the patient as a single bolus after a preselected time period has elapsed, the controller disposed within the interior space and configured prior to being disposed within the interior space,wherein the delivery device is wearable, disposable, and single-use.
