A lightweight wearable device to treat chronic wounds
At just the right frequency — inaudible to the human ear — ultrasonic waves can do more than monitor babies. They have the power to heal wounds.
A new wearable device designed by Dr. Peter Lewin of Drexel’s College of Biomedical Engineering, Science and Health Systems and Dr. Michael S. Weingarten of Drexel’s College of Medicine, could revolutionize the way doctors treat patients.
How does it work? It’s a battery-powered applicator that’s as small as a watch. With the flick of a switch, it sends low-frequency ultrasound waves directly to the wound.
These wound-healing wearables will potentially help the six million patients in the U.S. who suffer from chronic wounds — things like venous and diabetic ulcers, which are caused by aging, blood clots, obesity or diabetes. These kinds of wounds are painful and inconvenient, and can take months — or years — to heal.
But with this new device, all that could change. It’s so safe and simple that patients could operate it themselves, avoiding costly, time-consuming doctors’ visits. And that’s something we like the sound of.
