Abstract
An integral data logging system for a jet injector includes at least one electrical switch that changes state (e.g. from OFF to ON) during an injection procedure. The switch(es) are connected to an electrical circuit having a microprocessor, a clock and an electronic memory. When a switch changes state, this information along with the applicable date and time is recorded in the electronic memory. A communications link is provided to upload the stored data to a remote computer for subsequent manipulation and analysis to determine compliance with a prescribed dosing regimen. In one implementation, the injection duration is logged by using a trigger release switch and an end-of-stroke switch. The end-of-stroke switch is configured to change state after the drive bar of the injector transits through the injector tube. The injection duration is indicative of dose amount and can be used to distinguish between valid and invalid injections.
