Medical device for detecting an analyte in a body fluid

A medical device for detecting an analyte in a body fluid, the medical device comprising:

• an electronics unit having a sensor circuit;
• an analyte sensor having an insertable portion adapted for at least partially being inserted into a body tissue of a user, the analyte sensor comprising (a) two conductor paths configured for activating the sensor circuit and (b) two electrodes each comprising an electrode conductor path configured for transmitting a sensor current for detecting the analyte;
• an insertion cannula having the analyte sensor at least partially placed therein;
• a housing having an electronics compartment with the electronics unit at least partially received therein and the housing having an open channel at least partially surrounding the analyte sensor and the cannula;
• and
• a connector, wherein the insertion component is configured to retract from the open channel and thereby trigger electrical contact of the two conductor paths by the connector, which activates the sensor circuit.
