Device and Methods for Telehealth Wound Care

Background:

Open sores and wound healing are a pressing concern in medical care of limited mobility patients.  For instance, diabetic foot ulcers are associated with a 25% 5 year mortality rate as well as other complications. Likewise pressure ulcers (bed sores) can lead to life threatening infections and amputations.  Early intervention is critical for these patients.  Given the accessibility of the wounds and the mobility impairment of the patients, an ideal solution would allow physicians to monitor patients remotely to provide the needed care in a timely manner.

Technology Overview:

The heart of the WoundSight™ imaging system is a CMOS camera and light source capable of creating and processing multi-spectral images.  The software produces images of deep vascular structure, damage and flow blockage.  In addition, the device measures tissue oxygenation levels, blood perfusion, pulsation and remote photoplethysmography (rPPG).  The images and information can be transmitted to the cloud or physician offices allowing the device to either be a professional office or consumer-based product.

Advantages:

• Economical solution using commercially available components
• User friendly with simplified image processing
• Compact, non-contact and suitable for at-home care and telemedicine applications.

Applications:

General wound care but in particular at-home care and telemedicine of limited mobility patients.
