Smart bandage can monitor chronic wounds and dispense drugs

According to a recent article in the journal Small researchers led by Pooria Mostafalu sought to increase the rate of healing of chronic wounds by creating an intelligent bandage. "The wound environment is dynamic, but its cure rate can be improved by administering therapies at the right time," says the article.

The intelligent bandage can control both the temperature and the pH of the wound. If you detect a change, you can diagnose the problem and dispense medications as needed, thanks to a central processor, which a doctor can schedule to administer the treatment if certain conditions are detected. "A stimulus-sensitive drug delivery system comprising a hydrogel loaded with heat-sensitive drug carriers and an electronically controlled flexible heater is also integrated into the wound dressing to release medications on demand," the document says. The bandage will also control the treatment to determine if further steps are necessary. You can also provide status updates in real time via Bluetooth.

"Chronic wounds are one of the leading causes of amputations outside of war scenarios," said author Sameer Sonkusale at Digital Trends . Flexible, responsive bandages that can monitor a wound and administer treatment in real time could be key to reducing the number of amputations because they can treat a chronic wound quickly to prevent infection and promote healing.

The introduction of bandage technology is not a new concept; There are quite a few of these smart wound dressings floating around. However, this idea is promising, especially because the bandage itself can dispense the treatment instead of waiting for a doctor's response. It will be some time before it is available for the real world application (and it is very possible that it never will be). According to the article, the next step for smart bandaging is to test the technology on chronic wounds in animals to see if it is as effective as it was in the experiments.
