Abstract

An electronic injector including an electronic on-body injector for use with a patient to deliver a fluid through an injection device. The electronic on-body injector includes a fluid reservoir; a MEMS pump; a bolus injection needle, the bolus injection needle having a bolus injection needle tip aligned with the injection port, the bolus injection needle being slideably biased away from the injection port to define a gap; and a bolus needle button operably connected to the bolus injection needle to slide the bolus injection needle along the injection axis. The bolus needle button is operable to advance the bolus injection needle tip to close the gap and advance the bolus injection needle tip into the injection port to form a bolus injection flow path. The bolus needle button is further operable to activate the MEMS pump to deliver a predetermined bolus volume.
