Résumé

An optical device for the in noninvasive determination of the concentration of glucose or another analyte in blood using a combination of Raman spectrometry and PPG. The device includes an optical detector, preferably a CMOS imager including pinned photodiodes (PPD) to collect a time-variable signal and a logic circuit arranged to determine a glucose concentration based on variations in the optical signal happening in a frequency range compatible with the cardiac rhythm.

Blood glucose monitoring

Blood glucose monitoring is the use of a glucose meter for testing the concentration of glucose in the blood (glycemia). Particularly important in diabetes management, a blood glucose test is typically performed by piercing the skin (typically, via fingerstick) to draw blood, then applying the blood to a chemically active disposable 'test-strip'. The other main option is continuous glucose monitoring (CGM). Different manufacturers use different technology, but most systems measure an electrical characteristic and use this to determine the glucose level in the blood.

Continuous glucose monitor

A continuous glucose monitor (CGM) is a device used for monitoring blood glucose on a continual basis by insulin-requiring people with diabetes, e.g. people with type I, type II diabetes or other types of diabetes (e.g. gestational diabetes). A continuous glucose monitor consists of three parts: a small electrode placed under the skin, a transmitter sending readings at regular intervals (ranging from every 1 to 15 min), and a separate receiver.

Glucomètre

Un glucomètre ou lecteur de glycémie est un appareil permettant de mesurer rapidement le taux de glucose dans le sang (la glycémie), le plus souvent sur du sang capillaire. Ce type d'appareil est utilisé à l'hôpital par les soignants ou à domicile par les patients, notamment en cas de diabète sucré. Il existe plusieurs termes pour désigner cet appareil comme dextro (de la marque dextrostix) ou HGT (de la marque haemoglukotest).
