Noninvasive blood analysis by optical probing of the veins under the tongue
First Claim
Patent Images
1. A method for noninvasive analysis of at least one blood component in venous blood comprising the steps of:
- placing a probe in contact with a surface of a tissue directly under a big vein associated with an underside of a patient'"'"'s tongue, where the probe includes a tip having a radiation outlet and a response inlet so that both the radiation outlet and the response inlet are simultaneously in contact with the surface and where the outlet is connected to a light source via a light source conduit and the inlet is connected to a detector via a response conduit;
irradiating venous blood in the big vein with radiation having at least one frequency or wavelength;
detecting a response from the venous blood irradiated in the irradiating step; and
calculating a concentration of a blood component, a value of a blood parameter or a mixture or combination thereof in the venous blood from the response.

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.
