VeCare tech relays wound information whereas leaving the bandage in place

One of many ironies of treating continual wounds lies in the truth that when eradicating the dressing to examine the wound, you typically set again the therapeutic course of. A brand new kind of “good bandage” was designed with this drawback in thoughts, because it transmits wound information to an app on a clinician’s cell system.

Presently being developed by scientists on the Nationwide College of Singapore, the electronically enhanced bandage know-how is called VeCare.

The precise single-use bandage itself is made up of 4 layers. There is a backside layer that lies towards the wound, adopted by a flat microfluidic assortment system, a versatile electrochemical immunosensor, and a breathable protecting outer layer.

Because the bandage sits towards the wound, fluid from the damage is drawn into the microfluidic system by way of capillary motion. When a separate reusable battery-powered chip is plugged right into a lead extending from the immunosensor, the latter robotically begins analyzing the fluid.

Inside quarter-hour, it is capable of measure the pH and temperature of the wound website, which might in flip be used to find out if any an infection is going on. The system can be able to figuring out the kinds of micro organism current, and the extent of irritation. All of that information is wirelessly transmitted to an app on a close-by smartphone or pill.

Whereas medical doctors or clinicians might carry out the VeCare exams, it is also doable that sufferers might achieve this themselves in their very own properties, saving them pointless journeys to a clinic. In both case, if the app confirmed that all the wound parameters had been passable, the dressing might simply be left in place, leaving the wound undisturbed.

VeCare has already been the topic of a profitable scientific trial performed on sufferers with continual venous leg ulcers. The know-how is now being developed additional, so as to meet regulatory requirements and mass manufacturing issues.

A paper on the analysis, led by Prof. Lim Chwee Teck and Dr. Gao Yuji, was lately revealed within the journal Science Advances. The system is demonstrated within the following video.
