Formerly known as VivaScan, Grove Instruments closed its doors in July 2015. The firm had been is a medical device company developing a noninvasive - needle free - glucose measuring device. Groveâs patented technology is based on the seminal concept of the Optical Bridge and is unique among all NIR spectroscopic approaches to noninvasive blood glucose determination. Grove has developed a painless, bloodless, handheld, and easy to use non-invasive blood sugar monitor for use by diabetic individuals. Currently, diabetic individuals must stab themselves up to ten times per day to determine their blood glucose. Grove Instrumentsâ monitor, designed by a team of technical and clinical experts, responds to the noninvasive test needs of diabetic persons. A proprietary platform technology has evolved th eenable a personal hand held monitor. requiring only a simple, gentle squeeze of the ear or finger. The Grove Instruments competitive advantage is to have developed a cost effective, painless, handheld noninvasive monitor that provides results that are nearing clinical accuracy. The patented-protected platform method extracts sugar levels from differential measurements of IR light transmitted through the ear or reflected by the finger offering in prototype size, accuracy of results, manufacturing costs, and patent protection that is believed to provide important ompetitive advantag
