Abstract

A device for contacting a surface of a tissue within a patient's body to determine a physiological parameter of the patient. The device typically comprises a sensor (30) responsive to the physiological parameter and a probe (10) housing the sensor. The probe is constructed to allow the sensor to be secured at a sensing area (18) adjacent to a surface of a patient's tissue, without need for an adhesive and without disturbing the blood flow within the measurement region of the tissue. The device may also include a means (16) for reducing interference in the sensing area. Preferably, the device further comprises an indicating means (40) operably connected to the sensor for indicating an analyte quantity and/or concentration associated with the physiologic parameter. The invention also provides a method for determining a physiologic parameter of a patient.
