Abstract: A device that regulates, monitors, and provides data on the progress of a large-volume injector during its injection sequence. The device comprises an injector and a monitor assembly. The injector has a syringe having a plunger, and a biasing device that biases the plunger through the syringe. The monitor assembly comprises a resistance unit configured to resist movement of the plunger, a gear connected to the plunger by the resistance unit, and a control unit configured to monitor the position, and regulate the rotation, of the gear. Wherein linear movement of the plunger causes the gear to rotate so that the control unit generates information on the position of the plunger.

Abstract: A device that prevents the accidental activation and lockout of an autoinjector. In illustrative embodiments, a resistance unit is configured to resist deployment of the needle until a critical force is applied by the user to the autoinjector, at which point, the resistance of the resistance unit is overcome. Continuous application of force by the user after the resistance is overcome drives the delivery device to the injection site where the medication is administered.

Abstract: A metering device that improves the aseptic transfer of powder and reconstitution fluid into the metering device for medical use. In some implementations, the metering device comprises a housing, containing a metering chamber that defines a volume. The housing also has a connection portion, an extraction portion, and a metering member in fluid communication with the metering chamber. In other embodiments, the metering device additionally includes a dispensing aid that facilitates the dispensing of powder from a first container into the metering chamber through the connection portion. The connection portion is capable of insertion into a second container that contains fluid, thereby allowing a mixture of powder and fluid to form in the metering chamber. The mixture, then ready for use, is removable from the metering chamber through the extraction portion by an extraction device.
