Method and device for the identification of at least one substance of content of a body fluid
First Claim
1. A method for the identification of a substance of content of a body fluid, the method comprising arranging adjacent to a body tissue containing the body fluid at least one radiation source and a photo receiver, wherein the radiation source generates radiation of at least two different wavelengths, directing the radiation onto the body tissue the photo receiver receiving radiation that is reflected by the body tissue and/or receiving radiation that is reduced through the body tissue, directing at least at one point in time radiation of essentially the same wavelength from at least two radiation sources essentially synchronously onto the body tissue for penetration and/or reflection.

Abstract
A method and a device for the identification of at least one substance of content of a body fluid, wherein adjacent to a body tissue containing the body fluid at least one radiation source and a photo receiver are arranged. The radiation source generates radiation of at least two different wavelengths and the radiation is directed onto the body tissue. The photo receiver receives radiation reflected by the body tissue and/or reduced through the body weight. At least at one point radiation from two radiation sources with an essentially same wavelength is directed essentially simultaneously onto the body tissue for penetration and/or reflection.
