1. A device for contacting a sensing site within a patient'"'"'s body to determine a physiologic parameter of the patient, comprising:

  • a probe body having a top covered portion comprising a material that is substantially impermeable and a bottom portion having a perimeter structured to be positioned against the tissue surface, said perimeter defining a recess within said probe body;

    said probe body and said perimeter structured to prevent application of excessive pressure to the sensing site to allow for substantially undisturbed blood flow in the tissue; and

    a sensor housed within the recess, the sensor responsive to the physiologic parameter,wherein upon placement of the probe body against the sensing site said impermeable top portion and said perimeter are structured to create a covered, isolated measurement area within the recess that prevents the physiologic parameter from dissipating from the measurement area.
