A new sole to help heal diabetic ulcers

Scientists have developed a shoe sole that could help heal diabetic ulcers, a condition that often leads patients to lose their toes, feet or legs. Diabetes can lead to ulcers that patients do not feel or notice before seeing blood. These ulcers can not heal on their own. Researchers at Purdue University in the United States have made the healing process more portable for those who develop ulcers as a result of diabetes. "One of the ways to heal these wounds is to give them oxygen," said Babak Ziaie, a professor at Purdue.

"We have created a system that gradually releases oxygen throughout the day so that a patient can have more mobility," Ziaie said. Diabetic ulcers usually result from hyperglycemia caused by nerve damage that removes any sensation of sensation on the toes or feet. Without the ability to feel pain, blows and bumps tend to go unnoticed and the skin tissue breaks down forming ulcers. A large amount of sugar in the blood, as well as a dry skin resulting from diabetes, further slow down the healing process of the ulcer.
