Glucose Sensor
First Claim
1. A system (10) for non-invasive measurement of glucose concentration in a live subject (11), said system (10) comprising temperature sensing means (D1, D3, D4) for measuring body heat in respect of said subject (11), means (L1-L6, D5-D7) for measuring the concentration of haemoglobin and oxygenated haemoglobin in the blood of said live subject (11), irradiating means (14) for generating a measuring beam (16) and irradiating therewith a portion of said live subject (11), detector means (14, 17) for collecting measuring beam (16) radiation reflected by said live subject (11), means for determining from said reflected measuring beam radiation blood flow velocity in respect of said live subject (11), and means for determining glucose concentration in said live subject (11) as a function of said body heat, said haemoglobin and oxygenated haemoglobin concentrations, and said blood flow velocity.

Abstract
A system for the non-invasive measurement of glucose concentration in a live subject is disclosed. The system exploits the metabolic heat conformation method, and comprises temperature sensing means for measuring the body heat in respect of the subject and means for measuring the concentration of haemoglobin and oxygenated haemoglobin in the blood of the subject. The system further comprises irradiating means for irradiating a portion of the live subject, a detector for collecting the measuring beam reflected by the live subject, means for determining from the reflected measuring beam, the blood flow velocity in respect of the live subject, and means for determining glucose concentration in the live subject as a function of the body heat, the haemoglobin and oxygenated haemoglobin concentrations and the blood flow velocity.
