METHOD AND APPARATUS FOR LIGHT-WEIGHT, NON-INVASIVE, POINT OF CARE DIABETES SCREENING DEVICE

摘要

A multi-channel measurement device for measuring properties of human tissue,may comprise a microcontroller andfirst and second source/sensor complexes. The first source/sensor complex mayinclude a first housing having a first measurementportion, a first light sensor coupled to the microcontroller and exposed tothe first measurement portion, and a first plurality of lightsources coupled to the microcontroller and exposed to the first measurementportion. The second source/sensor complex may include asecond housing having a second measurement portion, a second light sensorcoupled to the microcontroller and exposed to the secondmeasurement portion, and a second plurality of light sources coupled to themicrocontroller and exposed to the second measurementportion. Each combination of an individually activated light source and one ofthe first and second light sensors provides a distinctmeasurement channel for measuring the absorption spectra of human blood andtissue.
