Claim 0:
1. An assembly of components for mounting an analyte sensor and an electronics compartment on a user's skin, the assembly comprising:
a housing defining a sealed sensor compartment, the housing comprising an upper cap, a lower cap, and an intermediate component, the intermediate component being attached to the upper cap and to the lower cap, the housing comprising an electronics compartment comprising an electronics unit;
an analyte sensor comprising an insertable portion adapted for at least partially being inserted into a user's body tissue; and
a cannula attached to the upper cap, the insertable portion of the analyte sensor being received inside the cannula,
an insertion aid configured for driving the cannula into the user's skin, and for inserting the insertable portion of the analyte sensor into the user's skin,
the insertion aid comprising a frame displaceable on the user's skin and configured to support the assembly on the user's skin during insertion of the analyte sensor,
the intermediate component defining a sealed opening, and the analyte sensor extending from the sealed sensor compartment through the sealed opening to the electronics compartment,
the analyte sensor being operably connected to the electronics unit,
the intermediate component defining a cannula aperture extending from an upper surface opening to a lower surface opening,
the lower cap being configured to seal with the lower surface opening of the intermediate component, the lower cap comprising an interior volume receiving the cannula and the insertable portion of the analyte sensor,
the upper cap being configured to seal with the upper surface opening of the intermediate component,
the lower cap being configured for removal prior to insertion of the analyte sensor,
the upper cap and the cannula being configured for removal from the intermediate component after insertion of the analyte sensor,
the cannula extending downwardly from the upper cap, through the cannula aperture, and beyond the lower surface opening, the insertable portion of the analyte sensor extending downwardly within the cannula and beyond the lower surface opening, and the lower cap extending downwardly from the intermediate component,
the housing having a sealed condition, prior to insertion of the analyte sensor, in which the upper cap and the lower cap form with the intermediate component the sealed sensor compartment surrounding and sealing the cannula and the insertable portion of the analyte sensor from an external environment.
