Abstract
A method for analysis of blood components or parameters is disclosed where a probe having an excitation outlet and a response inlet is placed in proximity to or in contact with a tissue of an underside of a patient'"'"'s tongue over a big vein in the tongue so that an excitation signal exits the outlet, produces a response which enters the inlet for detection and analysis.

45. A method for noninvasive analysis of blood comprising the steps of:
-
irradiating blood in a big vein associated with an underside of a patient'"'"'s tongue with radiation having at least one frequency or wavelength;
detecting a response from the blood irradiated in the irradiating step;
calculating a concentration of a blood component, a value of a blood parameter or a mixture or combination thereof from the response. - View Dependent Claims (46, 47, 48, 49, 50, 51, 52, 53, 54, 55, 56)

57. An apparatus for noninvasive blood analysis comprising:
-
a probe including a tip having a radiation outlet and a response inlet, where the probe tip is adapted to be placed in proximity to or in contact with a surface of a tissue over a big vein associated with an underside of a patient'"'"'s tongue;
a light generation/delivery system including a light source capable of generating at least one frequency of light, and a light conduit interconnecting the light source with the radiation outlet, where the system is adapted to deliver radiation to blood in the big vein; and
a detector/analyzer system including a detector adapted to detect a response from the irradiated blood via the response inlet and an analyzer adapted to convert the detected response into a concentration of a blood component and/or a value of a parameter of the blood. - View Dependent Claims (1, 58, 59, 60, 61, 62, 63, 64, 65, 66, 67, 69)
