A Continuous Non-invasive Blood Glucose Monitoring System Based on Photoacoustic Spectroscopy

Technology Description

Diabetic patients are required to make a minimum of 3-4 measurements each day. Presently, most diabetics draw drops of blood from their fingertips and test it using a handheld device to get their glucose values. The innovation takes these blood glucose measurements in a non-invasive manner without any need for drawing blood at regular intervals. It makes use of an analytical technique known as photoacoustic spectroscopy for making these measurements. The device takes these photoacoustic measurements from the fingertips of a person and uses it to predict the blood glucose concentration. The device initially takes photoacoustic measurements from the subject and uses reference glucose concentration values taken at the same instant for calibration of these photoacoustic measurements, i.e., to say what value of photoacoustic signal corresponds to a particular glucose concentration. Once calibrated, the device operates independently, taking photoacoustic measurements at regular intervals and predicting the blood glucose concentration using the same. The device is aimed at daily use by diabetic patients to monitor their glucose, or for use in intensive care units for continuous monitoring of patients. It can also be used by physicians to assess patient health for diagnosis.

The device also requires little or no user intervention during measurement, allowing for greater patient freedom. It also has no consumable requirements during measurement keeping waste at a minimum.
