Medical injections and related devices and methods

Abstract

Systems, devices, and methods include an autoinjector including a housing; a connectivity region configured to be accessed at a region of the housing; a needle arranged at a distal end of the housing; a container disposed within the housing and configured to contain medicament; and a plunger slidably disposed within the container. A plunger rod is configured to push the plunger through the container to dispense the medicament through the needle when the container contains medicament. The needle guard is configured to retract when an insertion force is applied to the needle and to extend when the insertion force is removed. A mechanism is configured so that a dispensing movement of the plunger rod, a retraction movement of the needle guard, and/or an extension movement of the needle guard generates an electrical state change. A first sensor is configured to detect the electrical state change.
