1. A sensor introducer assembly, comprising:

  • a housing comprising a base portion configured to be placed on a skin surface of a patient;

    an analyte sensor; and

    an insertion unit disposed on the base portion and operatively coupled to the analyte sensor;

    wherein the insertion unit includes a compressible introducer mechanism coupled to an introducer, wherein the compressible introducer mechanism is configured to displace at least a portion of the analyte sensor and the introducer to an insertion position under the skin surface, and wherein the introducer includes a sharp portion configured to releasably couple with the at least the portion of the analyte sensor;

    wherein the compressible introducer mechanism moves from a non-compressed state to a compressed state in response to a manual force being directly applied to a surface of the compressible introducer mechanism, wherein when the compressible introducer mechanism moves from the non-compressed state to the compressed state the at least the portion of the analyte sensor and the introducer are displaced to the insertion position;

    wherein the compressible introducer mechanism is configured to automatically withdraw the sharp portion of the introducer from under the skin surface while retaining the at least the portion of the analyte sensor at the insertion position; and

    wherein the introducer is contained within the housing when the compressible introducer mechanism is in the non-compressed state.
