Are you a diabetic patient and frustrated with insulin injections and finger pricks? Don’t worry; from now there is no need to injections. Thanks to the new smart-phone based system, which automatically controls blood-sugar levels.
This latest smartphone combined with a tiny sensor and wearable insulin pump, can stand in for pancreas, monitoring blood-sugar levels and delivering insulin as needed, researchers said.
Boris Kovatchev, lead researcher and director of University of Virginia Center for Diabetes technology. “We have been working on this specific artificial pancreas since 2006 and this system works with a readily available blood-glucose sensor. That sensor reads blood-glucose levels every five minutes and wirelessly reports the results to a specially designed app on a nearby android smartphone,” Boris adds.
Researchers have come up with an improved version of the smartphone app algorithm that does not aim for a specific blood-glucose number, but rather a “zone.”
These patient-specific short ranges of healthy blood-glucose levels are easier targets that can be stably maintained, avoiding constant adjustments that can lead to swings, Francis Doyle III, dean of Harvard’s Paulson School of Engineering and Applied Sciences said. The new algorithm will be able to adapt to each patient’s sugar shifts and insulin sensitivity.
