Patent ID: 7430445

Claim:
An apparatus for noninvasive blood analysis comprising: right side and left side sections adapted to engage one or more teeth on each of a right side and left side of a patient's jaw, two transition sections extending downwardly from each of the side sections, a middle section interposed between the two transition sections adapted to be proximate to or in contact with an underside of a patient's tongue, where the middle section includes; a emitter, and a receiver, where the emitter and the receiver are adapted to be proximate or in contact with a surface of a tissue over a big vein associated with an underside of the 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 a 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 a 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.
