Patent ID: 8855732

Claim:
A portable non-invasive human metabolic condition measuring apparatus, comprising: a miniature casing adapted for insertion into a body cavity of a patient or placement adjacent the patient's body; at least one micro-light source located within said miniature casing, for emitting an incident light having a wavelength from 329 nm to 473 nm to excite a metabolite to emit a fluorescent signal having a wavelength from 405 nm to 572 nm; at least one optical filter, located within said miniature casing adjacent the micro-light source, for filtering an optical signal other than the fluorescent signal; at least one micro receiver, located within said miniature casing adjacent the micro-light source, for receiving a fluorescent signal passed through the optical filter; an amplification circuit, located within said miniature casing and electrically coupled to the micro receiver, for amplifying the fluorescent signal; a microprocessing unit, positioned external said miniature casing and electrically coupled to the amplification circuit, and including a filter circuit and an analog/digital conversion circuit, for filtering the amplified fluorescent signal, performing an analog/digital signal conversion, and calculating a computational value related to the metabolite by a computational processing; and an elongated handle for structurally and electrically coupling said microprocessing unit to said miniature casing, said elongated handle adapted to be grasped by a hand of a user for manipulating the miniature casing.
