Treatment of chronic wounds usually involves the use of different medications at different stages of the healing process. Newly developed electronic bandages can make this happen, but you don’t have to remove it for each procedure. The “smart” bandages are based on previously developed devices and were created by teams at the University of Connecticut, the University of Nebraska at Lincoln and Harvard Medical School.
It is equipped with a small storage unit for the required drugs. When selectively activated by a smartphone-sized wireless controller, the tiny needles at the bottom of these containers deliver the drug to a relatively deep wound. The process is said to be quite easy.
According to scientists, injecting drugs in this way is more effective than simply applying them to the skin. But perhaps more importantly, the device does not need to remove the bandage every time more drugs are needed, nor does it need to be damaged. In fact, it can be imagined that bandages can be operated over the Internet, and that caregivers can not even be in the patient’s room.
Recently, researchers found that when the technique was used to treat whole-layer skin wounds in diabetic mice, it was superior to locally used drugs. The animal’s wounds are completely healed and there are few scars.
“This is an important step in designing advanced bandages to facilitate the healing of incurable wounds,” said Ali Tamayol, an associate professor at the University of Connecticut. The bandages do not need to be replaced continuously. “
The study was presented in a paper published this week in the journal Advanced Functional Materials.
