Claim Text:
1. A device for contacting a tissue sensing site of a patient to determine a physiologic parameter of the patient, comprising: a probe body having a longitudinal axis, a top covered portion parallel to said longitudinal axis, said top portion comprising a material that is impermeable and a bottom open portion defining a perimeter structured to be positioned against a surface of the tissue sensing site, said perimeter defining a recess therewithin, 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 responsive to a concentration of an analyte through a chemical reaction with a reactant, said analyte concentration representative of the physiologic parameter, said sensor having a first end and a sensor body, said first end coupled to said probe body and said sensor body unobstructedly suspended with the recess; 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 such that the sensor is exposed to the tissue sensing site and the covered, isolated measurement area prevents the analyte from dissipating from the measurement area.
