    Abstract: An automatic injector for delivering a pharmaceutical substance from a reservoir of a cartridge, the cartridge interconnected to a needle at its distal end and mechanically coupled to a plunger driver at its proximal end, the injector comprising a connecting feature on the cartridge a contact surface for contacting an injection site a frame connected to the contact surface, the frame having an interference element with a distal stop, the interference element sized to slidably link to the connecting feature and allow the cartridge to slide up to the distal stop, a snap element allowing the interference element to receive the connection feature, but inhibiting disconnection of the cartridge; the frame further comprising a driver mount, for fixedly containing a plunger driver, the driver for driving a plunger to empty the reservoir of the cartridge through the needle to inject fluid from the reservoir into the injection subject.

    Abstract: An injector device for medical use includes a needle, a barrel in fluid communication with the needle, and a plunger sealing the barrel's proximal end. The injector device further includes a needle cover, a housing with a channel, and an adhesive base for securing the injector to a patient's skin. The housing channel has openings for the barrel and needle. A handle and coupler mechanism facilitate the removal of the needle cover and adhesive cover from the adhesive base. An assembly method involves installing the barrel into the distal housing channel, ensuring fluid communication with the needle, sealing the barrel's proximal end with a plunger, and coupling the distal housing to a proximal housing. The handle is then pulled to remove the adhesive cover and needle cover from the adhesive base, preparing the injector for use.

    Abstract: A patch injector (10) for parenteral administration of a drug to a drug recipient has a drug-cartridge module (14) attached to a power-pack module (12) and to a drug-recipient interface module (16). A compressed, elastic power element (18) disposed in the power-pack module (12) is coupled to a plunger (30) movably disposed in a drug reservoir (22) in the drug-cartridge module (14). An injection needle (24) at the distal end of the drug reservoir (22) is oriented orthogonal to the drug reservoir (22) and generally toward a skin-contact surface (28) extending parallel to the longitudinal drug-reservoir axis (22A). The power element (18) is configured to displace the plunger (20) distally into the drug reservoir (22) and to move the injection needle (24) toward the skin-contact surface (28) when the power element (18) expands distally along the drug-reservoir axis (22A).

    Abstract: A system and method are provided for preventing a sharp stick hazard from a needle tip of an automatic injector device. In some embodiments, a skin contact surface of the device is attached to an injection site, for example by an adhesive. Optionally a locking mechanism holds a needle extended into an injection site. A body of the device is optionally movably attached to the skin contact surface. Pulling the body away from the injection site optionally moves the body with respect to the skin contact surface. Movement of the body with respect to the skin contact surface optionally moves interlinked parts of the locking mechanism, releasing the locking mechanism.
