An inexpensive bandage that speeds healing time by 30 percent has been developed by researchers.
The dressing uses an electric field on chronic wounds and is the work of a US team at North Carolina State University .
In animal testing, wounds healed a third faster compared to those treated with conventional bandages.
Chronic wounds are open wounds that heal slowly, if they heal at all.
For example, sores that occur in some patients with diabetes are chronic wounds.
These wounds are particularly problematic because they often recur after treatment and significantly increase the risk of amputation and death.
One of the challenges associated with chronic wounds is that existing treatment options are extremely expensive, which can create additional problems for patients.
The new dressings, which are disposable, have electrodes on one side and a small, biocompatible battery on the other.
The dressing is applied to a patient so that the electrodes come into contact with the wound.
A drop of water is then applied to the battery which activates it to produce an electric field for several hours.
The electrodes are designed in a way that allows them to bend with the bandage and conform to the surface of the chronic wounds, which are often deep and irregularly shaped.
