Classification: CPC A  B | IPC A  B

Claim 29:
30. A mounting assembly for mounting an analyte sensor and an electronics compartment on a user,
the analyte sensor including an insertable portion adapted for at least partially being inserted into the user's body tissue, the analyte sensor being configured to be mounted with the insertable portion extending through the user's skin,
the housing comprising an electronics compartment at least partially receiving an electronics unit operably connected to the analyte sensor, the housing further comprising an intermediate component comprising an upper surface including an upper surface opening and a lower surface including a lower surface opening, the intermediate component defining a cannula aperture extending from the upper surface opening to the lower surface opening, and the housing being configured to be mounted on the user's skin,, the mounting assembly comprising:
a frame configured to support the assembly on the user's skin during insertion of the analyte sensor;
a lower cap configured to seal with the lower surface opening of the intermediate component, the lower cap being configured for removal from the intermediate component prior to insertion of the analyte sensor;
an upper cap configured to seal with the upper surface opening of the intermediate component; and
a cannula,
the intermediate component, the lower cap, and the upper cap being configured to form a sealed sensor compartment, the cannula and the insertable portion of the analyte sensor being sealed within the sealed sensor compartment,
the cannula being attached to the upper cap and extending downwardly within the sealed sensor compartment from the upper cap, through the cannula aperture, and beyond the lower surface opening,
the analyte sensor being at least partially received in the cannula and the insertable portion of the analyte sensor extending downwardly within the cannula, from the upper cap, through the cannula aperture, and beyond the lower surface opening,
the lower cap extending downwardly from the lower surface of the intermediate component and comprising an interior volume receiving the cannula and the insertable portion of the analyte sensor,
the sealed sensor compartment being connected to the electronics compartment via a sealed opening, the analyte sensor extending through the sealed opening from the sealed sensor compartment to the electronics compartment, and
the upper cap and cannula being configured for removal from the intermediate component after insertion of the analyte sensor.
