  • Patent number: 10352895
    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.

  • Patent number: 8427817
    Abstract: A handheld diabetes manager having a blood glucose measurement engine comprises a housing having a blood glucose measuring engine and a printed circuit board disposed in the housing. A touch screen can be coupled to the housing. The touch screen can have a transparent portion surrounded by a non-transparent portion. The non-transparent portion can have adhesive thereon that seals the touch screen to the housing. A flexible connector can electrically connect at least two independent electrical leads between the touch screen and the printed circuit board. An antenna assembly can be disposed in the housing and comprise a molded carrier, a conductive portion on the molded carrier and a speaker. The conductive portion can be electrically connected to the printed circuit board and be configured to receive a radio signal. The carrier can include a recess that receives the speaker and is configured to project sound from the speaker.
