A wearable for treating antibiotic-resistant infections

Researchers have developed a wearable solution that allows a patient to receive treatment of antibiotic-resistant infections and woundswithout leaving home.

About 6 million people in the United States are affected by chronic wounds. The rapid increase of life-threatening antibiotic-resistant infections has resulted in challenging wound complications with limited choices of effective treatments.

Now, researchers from Purdue University has developed a wearable solution that allows a patient to receive treatment without leaving home. "We created a revolutionary type of treatment to kill the bacteria on the surface of the wound or diabetic ulcer and accelerate the healing process," said Rahim Rahimi, an assistant professor of materials engineering at Purdue. "We created a low-cost wearable patch and accompanying components to deliver ozone therapy."

Ozone therapy is a gas phase antimicrobial treatment option that is being used by a growing number of patients in the U.S. In most cases, the ozone treatments require patients to travel to a clinical setting for treatment by trained technicians. "Our breathable patch is applied to the wound and then connected to a small, battery powered ozone-generating device," Rahimi said. "The ozone gas is transported to the skin surface at the wound site and provides a targeted approach for wound healing. Our innovation is small and simple to use for patients at home."

The work is published in the journal Frontiers in Bioengineering and Biotechnology.
