A Noninvasive Method for Diabetes Patients
IFIA Best Invention Medal was awarded to Dr. Artur Rydosz and Assist .Prof. Konstanty Marszalek from AGH University of Science & Technology, Krakow, POLAND for their innovation titled “Preconcentrator of gas samples” showcased in International Invention and Design Competition 2017 (IIDC).
Current management of diabetes is mainly based on repeated testing of blood while the blood glucose measurement is an invasive method with serious consequences for the patient in case of infection. This possibility significantly reduces the number of glucose test made by people.
Frequent blood testing is especially necessary for patients undergoing insulin treatment. The global recommendation to self blood glucose concentration monitoring is no less than 3 times daily. It is expensive, unpractical and even painful. The new approaches for diabetes control have been discussed for a long time. The scientists around the world are looking for non-invasive methods. The breath analysis is one of them. The proposed invention allows to:
- develop fully noninvasive method for glucose monitoring based on exhaled breath analysis with special emphasis to exhaled acetone detection
- be miniaturized in any technology, incl. CMOS/VLSI
- build a “Lab of Chip” device with e-health application to continuously monitor the glucose concentration and inform the medical center or main doctor
The present invention can be developed as an electronic device for non-invasive exhaled acetone measurement, which is correlated to the glucose concentration in the blood. The proposed method allows to change the conventionally used monitoring of diabetes, which is a civilization disease affecting over 350 million of people all over the world. The main advantage of the proposed invention is that can be realized in any technology. The presented realization was made in ceramic – LTCC technology.
The presented device permits to detect very low gas content in gas mixture using commercial gas sensor with sensitivity lower then gas content in mixture. Preconcentrator is a part of a whole system with integrated gas sensor matrix, control unit and communication unit.
