1. An apparatus, comprising:

  • a sensor insertable into a dermal layer of skin of a subject and adapted to sense an analyte level in the dermal layer;

    a base from which the sensor extends, the base being adapted to contact the skin of the subject with the sensor inserted into the dermal layer;

    an insertion needle; and

    a perfusion modulator adapted to increase perfusion in the dermal layer, wherein the perfusion modulator is at least one protrusion located on the base,wherein the at least one protrusion is adapted to apply pressure to increase perfusion in an area local to the sensor when inserted into the dermal layer, andwherein the insertion needle extends from the first protrusion adjacent to the sensor.
