Test strip ejector for medical device
First Claim
1. A fluid testing medical device configured to receive a test strip, comprising:
- a connector in the fluid testing medical device and arranged to make electrical contact with a test strip inserted in the fluid testing medical device; and
a test strip ejector system connected to the fluid testing medical device, including;
first and second guide rails;
a sled having opposed first and second leg sets each having at least two legs configured to partially capture there between the first and second guide rails, each of the legs positioned externally to and retained in sliding continuous contact with one of the first or second guide rails to limit sled motion to a loading direction and an ejection direction that is opposite the loading direction;
an arm connected to the sled and rotatably movable between first and second positions, wherein rotation of the arm from the first position to the second position moves the sled in the ejection direction to eject the test strip from the fluid testing medical device and rotation of the arm from the second position to the first position moves the sled in the loading direction; and
an ejection button connected to the arm, wherein depression of the ejection button in a direction perpendicular to the loading and ejection directions of the sled provides a displacement force that moves the arm from the first position to the second position and the sled in the ejection direction to eject the test strip from the fluid testing medical device.

Abstract
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.
