Abstract:
A glucose measuring device for determining the concentration of glucose in fluid within a body part of a subject, comprising:a) at least one light source emitting near infrared or infrared light having a wavelength of between 640 and 1000 nm to illuminate the fluid, and at least one receptor associated with and opposite from said light source for receiving light emitted by said light source and transmitted through the fluid and body part of the subject and generating a transmission signal representing the light transmitted from said first light source; b) a support piece having a first plate for supporting said light source, and a second plate movable with respect to said first plate for supporting said receptor associated with said light source; c) said support piece adapted to place a body part of a subject intermediate said first and second plates and to illuminate the body part and fluid using said light source; and d) a signal analyzer interconnected with said receptor for receiving said transmission signal and for determining from the transmission signal the glucose concentration in the fluid within the illuminated body part.
