Abstract
A sensor dispensing instrument adapted to handle a sensor pack containing a plurality of sensors and to perform a test using one of the sensors. The sensor dispensing instrument includes an outer housing and a mechanical mechanism contained therein for rotating the sensor pack and ejecting one of the sensors from the sensor pack and through a sensor slot on the housing. The sensor dispensing instrument also includes a sensor actuator to engage with a sensor disposed in the sensor slot, and a sensor release that is movable to disengage the sensor actuator from the sensor disposed in the sensor slot and permit the discharge of the sensor.
