Analyte Monitor
First Claim
1. An analyte monitoring device having a housing, the device comprising:
- a. a plurality of needles, each having a tip, a retracted position, a position wherein the tip is extended from the housing a distance adapted to pierce skin;
b. an electrically or spring powered needle pushing apparatus movable to separately engage each of the needles to move each from the retracted position to the extended position;
c. an energy source located within the housing;
d. a plurality of analysis sites comprising an analysis preparation, each adapted to receive liquid from the needles to wet the analysis preparation;
e. one or more light sources adapted to direct light at the analysis sites;
f. one or more light detectors adapted to receive light from the analysis sites; and
g. a processor.
