Diabetes ulcers? A new shoe pad could provide ongoing treatment – ScienceDaili


Diabetes can lead to ulcers in which patients do not even feel or notice the appearance of blood. And because the ulcer can not be treated alone, 14 to 24 percent of diabetics in the United States who experience them end up losing fingers, legs or legs.

Purdue University researchers have developed shoes for shoes that could help treat the treatment process for 15 percent of Americans who develop ulcer like diabetes.

"One way to cure these wounds is by giving oxygen," said Babak Ziaie, professor of electrical engineering and computer engineering Purdue. "We have created a system that gradually releases oxygen throughout the day so that the patient can have greater mobility."

The diabetic circulation usually comes from high blood sugar that damages the nerves, which takes away the sensation of the finger or the foot.

Without the ability to feel pain, the bumps and dents suddenly disappear and the skin tissue breaks down, making the ulcers. Many sugars in the bloodstream, together with dried skin due to diabetes, further slow down the process of ulcers.

"Usually treat ulceration by removing the devitalized tissue from the surface of the wound and helping the patient find ways to take weight from the affected leg," said Desmond Bell, a wound dresser and ampution prevention assistant at the Memorial Hospital in Jacksonville, Florida, and founder of Save the Leg, Save a Life Foundation.

"The gold standard for the treatment of ulcers is a patient who has full contact, which provides a protective footprint. If we could test how well these cartridges are delivering oxygen at the site of the wound from within the role, then this could be a way to help the healing process," said is.

Purdue researchers used lasers to form silicone rubber in insoles, and then create oxygen-free tanks only on the part of the foot where the ulcer is located. IouTube video is available at https: //

The work was compared to the celebration of Purdue's Giant Leaps, confirming the University's global progress in health, longevity and quality of life as part of Purdue's 150th anniversary. This is one of four themes of the Ideas Yearly Celebration festival, which aims to show Purdue as an intellectual center that solves problems from the real world.

"Silicone is flexible and has good oxygen permeability," Hongjie Jiang, a postdoctoral researcher in electrical and computer engineering, said. "Laser processing helps us adjust this bandwidth and enter only the site of the wound, which is hypoxic, not poisoning the rest of the foot with too much oxygen."

According to team simulations, the cartridge can deliver oxygen for at least eight hours a day under the pressure of someone weighing about 53-81 kilograms (117-179 pounds). But the cartridge can be adapted to take on any weight, say the researchers.

The team predicts a manufacturer who sends a package of filled cartridges adapted to his or her early location, based on a "wound profile" obtained from the doctor's prescription and footprint.

"This is a mass adjustment at a low price," said Vaibhav Jain, a recently graduated machine programmer named Purdue and currently a research associate in electrical and computer engineering.

Then, researchers want to create a way for 3D to print the entire interior, instead of first printing the mold, and then laser processing the pattern. They also plan to test the inside of diabetic ulcers, in order to further assess how well the healing process is doing well.

"We want to bring this technology to the user by addressing the independent technical needs to simplify the production flow," Jain said.

The team published their work in the September issue Materials Research Social Communication, the Cambridge Core magazine. Funding for this work was provided by NektFlek PC 1.0 project.

The patent is pending on cartridge technology. The team is currently looking for corporate partners.
