Abstract
The invention provides a device for contacting a surface of a tissue within a patient's body to determine a physiologic parameter of the patient. The device typically comprises a sensor responsive to the physiologic parameter and a probe housing the sensor. The probe is constructed to allow the sensor to be secured at a sensing area 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 for reducing interference in the sensing area. Preferably, the device further comprises an indicating means 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.
