A system and method for testing and ejecting a test strip of a fluid testing medical device. The system includes parallel first and second guide rails defining a rail cavity between the guide rails. A sled includes a sled post and opposed first and second side leg sets each having at least one deflectable leg. Each of the deflectable legs is externally slidably engaged to one of the guide rails limiting the sled to only sliding motion in either a loading direction or an opposite ejection direction. An actuator arm is rotatably connected to a mechanism assembly. The sled post is received in an actuator arm slot. Actuator arm rotation in a loading rotational direction displaces the sled in the loading direction in a sliding motion. Subsequent opposite rotation of the actuator arm in an ejection rotational direction displaces the sled in the ejection direction and ejects the test strip.

An electronic device may include a battery well and a plurality of tabs. The battery well may receive a disk-shaped battery and may include an annular sidewall, an open end, an end wall and a recess. The open end may be disposed at a first end of the sidewall. The end wall may be substantially perpendicular to the sidewall at a second end of the sidewall and axially between the recess and the open end. The recess may be disposed at the second end of the sidewall and adjacent the end wall. The recess may be adapted to receive a portion of the battery therein. The tabs may be disposed at the open end and may extend radially inward from the sidewall to releasably retain the battery in the battery well. The tabs may define a plane that is substantially parallel to the end wall.

A test strip ejector system for receiving and ejecting a fluid testing medical device test strip includes a mechanism assembly supported by the device whereby user actuation of the mechanism assembly induces displacement of the test strip in at least a test strip ejection direction to eject the test strip. The mechanism assembly includes a power source and an electric motor such as a piezo-electric linear micro motor connected to the power source. The electric motor has an armature displaced when the electric motor is energized. A digital display/user interface is provided. Selection of an ejection function presented on the digital display/user interface initiates operation of the electric motor and displacement of the armature thereby displacing the test strip in the ejection direction. An operating system including a microprocessor is connected to the display/user interface. The microprocessor controls direction of operation and operating speed of the motor.

A handheld test strip illumination device includes a housing. A strip connector positioned within the housing receives a first portion of a test strip in a test strip test position. A light source is positioned within the housing. A lens/light reflecting device is aligned to receive photons emitted from the light source and direct the photons onto the first portion of the test strip within the strip connector. The first portion of the test strip within the strip connector includes a longitudinal transparent layer receiving the photons emitted from the lens/light reflecting device within the housing. The photons pass through the longitudinal transparent layer and are emitted from the longitudinal transparent layer in a second portion of the test strip positioned outside of the housing, thereby illuminating a dose area of the test strip.
