For some time now, sterilized ozone has been used to treat chronic wounds such as diabetic skin wounds,media reported. Now, thanks to the emergence of an experimental new wearable system, the treatment will soon become more practical and effective. Typically, patients using ozone therapy must go to a clinic, where their antibiotic-resistant wounds are treated by trained technicians. This can be difficult for patients living in remote areas, with reduced mobility, or in areas where clinicians are in short supply.
In addition, patients must not only wait around the clinic for treatment, but also stop as soon as the treatment is over.
A team from Rahim Rahimi, an assistant professor at Purdue University in Indiana, set out to address these limitations.
To this end, the researchers created a prototype of a portable, wearable device. It consists of a breathable patch that temporarily adheres to the skin above the wound and is then attached to a compact, battery-powered ozone-producing device using a silicone hose.
“Ozone is delivered to the skin surface of the wound site, which in turn provides a targeted method for wound healing,” says Rahimi. “
Now, researchers are planning animal trials, which could lead to human clinical trials.
