World Media & Technology Corp Press Release: Launch Of World's First Wearable, Non-Invasive, Continuous, Blood Glucose Estimation Technology Using WRMT's Smart Wristband, Helo, Will Generate Recurring Revenues For WRMT
- the company's research activity is generating accurate non-invasive, continuous blood glucose estimates. - seeking full integration of the algorithm in the HELO platform to offer blood glucose estimation as a service in Q4 2017. - photoplethysmograph (PPG) to estimate blood glucose levels and incorporate the technology into a wearable device to provide convenient, non-invasive blood glucose estimation and logging on a continuous basis. - HELO is not a medical device, but continuous measurement of blood glucose estimates are expected to be helpful in understanding blood glucose changes over time, aid compliance and support a pre-diabetic seeking to change their lifestyle to avoid diabetes. - in the event that Helo detects a blood glucose problem, Helo's Guardian service will automatically alert the wearer and their care giver.
According to the International Diabetes Federation: - 415 million people worldwide (1 in 11 people) have diabetes. - Diabetes consumed 12% of global health expenditure ($673B) in 2015. - The American Diabetes Association advises that in the US, nearly 30 million (1 in 8) people have diabetes and $1 in $5 health care dollars is spent caring for people with diabetes. - Americans with diagnosed diabetes incur average medical expenditures of about $13,700 per year, of which about $7,900 is attributed to diabetes.
This research report provides a great overview of how PPG technology works:
Photoplethysmography (PPG) technology has been used to develop small, wearable, pulse rate sensors. These devices, consisting of infrared light-emitting diodes (LEDs) and photodetectors, offer a simple, reliable, low-cost means of monitoring the pulse rate noninvasively. Recent advances in optical technology have facilitated the use of high-intensity green LEDs for PPG, increasing the adoption of this measurement technique. In this review, we briefly present the history of PPG and recent developments in wearable pulse rate sensors with green LEDs. The application of wearable pulse rate monitors is discussed.
Another description of how PPG works: Yellow and/or green LED optical sensors are used to measure the amount of light refracted in the blood vessels utilising the PPG technique. An algorithm is then applied to translate the data from the refracted light into a continuous measure of HR (heart rate).
