Smartphone Solution Digitizes Chronic Wound Care

The Healthy.io (Tel Aviv, Israel) digital wound management solution uses computer vision algorithms and visual calibration methods in order to turn the smartphone camera into a wound documentation and measurement tool. Using a smartphone app and two round calibration stickers placed around the wound, nurses can quickly scan the wound to acquire and track dimensions quickly and effectively. The app also constructs a three-dimensional (3D) image of the wound, enabling more comprehensive documentation.

The app measures wounds and captures standardized visual records over time, eliminating human error and discrepancies that are common in current methods, which rely on subjective analysis and inaccurate measurement. In addition, it provides qualitative and quantitative characteristics of the wound, such as location, wound type, pain level, odor, exudate, and more. The app also documents the administered treatment plan, creates reports summarizing wound progress, and provides reference to past treatment and photos.

“Nurses, already overextended, are on the front line of wound care, and are the real heroes, but the tools they are using today haven't changed in decades,” said Yonatan Adiri, founder and CEO of Healthy.io. “We believe this is the heart of the problem and why we have created a solution that will help them accurately track wound progress over time. Our expertise, robust partnerships, and track record in clinical grade image and color recognition position us to make a significant impact on this market.”

An essential part of weekly wound assessment is measuring the wound, and consistent technique is vital for accuracy. The most common type of measurement is linear measurement, also known as the “clock” method, measuring the longest length, greatest width, and greatest depth of the wound, using the body as the face of an imaginary clock. However, such linear methods are inaccurate, as they do not take into account changes in wound shape and depth.
