Noninvasive Blood Glucose Detector and Method Using IR

摘要

The blood glucose (BG) detector (BGD) stores baseline BG data therein. The BGD has a housing with legs forming a U-shaped sensing channel for a finger web or ear antihelix. The sensory channel limits insertion of the web/antihelix. A positional light sensor subsystem audibly and/or visually indicates a test-to-test detection position. A BG sensor on the legs uses IR 1550 bandwidth light to detect BG by transmission through the web/antihelix ro generate a detected BG signal. A comparator (in processor-memory system) compares detected BG signal to baseline BG data and generates a displayable BG level to the user via a display module. Alternatively, a leg-to-leg distance sensor may be used. A keypad enables upload of the BD baseline data (or an I/O port).
