Claim 15:
16. An infusion device comprising:
a first unit defining a first housing, wherein the first housing defines a first channel extending through the first housing, a second channel extending through the first housing, and a fluid access, and wherein the first unit includes processing circuitry, a fluid reservoir, and a fluid pump in fluid communication with the fluid access; and
a second unit defining a second housing configured to engage the first housing, the second unit comprising:
a cannula having a first end and a second end; and
a sensor;
a first insertion needle releasably carrying the cannula and configured to extend through the first channel; and
a second insertion needle releasably carrying the sensor and configured to extend through the second channel, wherein:
the first housing is configured to substantially secure the second housing from movement relative to the first housing when the second housing engages the first housing,
the first insertion needle is configured to extend a portion of the cannula including the first end through the first channel when the first insertion needle extends through the first channel,
the second insertion needle is configured to extend a portion of the sensor through the second channel when the second insertion needle extends through the second channel,
the second end of the cannula is configured to insert through the fluid access when the second housing engages the first housing, wherein the cannula is configured to establish fluid communication from the first end of the cannula to the fluid reservoir when the second end of the cannula inserts through the fluid access, and
the infusion device is configured to electrically connect the sensor and the processing circuitry when the second housing engages the first housing.
