In a Small magazine article on July 6, a team of researchers from Tufts University, near Boston, presented a prototype bandage smart health connected. The latter could facilitate the treatment of chronic wounds.

In a medical setting, a simple dressing can bring a lot of complications. It is not enough to train caregivers to protect and facilitate the healing of an injury. It is necessary to be able to change and observe the evolutions of a long wound to be treated. This problem can happen to people with diabetes or chronic venous insufficiency. These wounds, which are difficult to relieve after 4 to 12 weeks, despite local treatment, require constant attention.

According to an article published on the journal Web Small, a team of researchers from Tufts University led by Pooria Mostafalu has developed a way to accelerate the healing of chronic wounds: a smart health connected bandage.

The smart health connected bandage, a condensate of technologies

"The wound environment is dynamic, but their healing rate can be improved by timely therapeutic delivery", Can we read in this article.

The famous smart health connected bandage is equipped with sensors to measure the temperature and pH of a wound in real time. The system consists of a 3D printed structure that holds the sensors in place, a patch containing antibiotics and gel, and a control circuit surmounted by a microprocessor. The tape smart health connected to the control module communicates in Bluetooth with the doctor's smartphone. The control box can also automatically manage the administration of drugs. To do this the doctor programs the device to react to certain changes in the wound condition.

Automated medical treatment

The article explains this feature of the smart health connected bandage: "A stimulus-sensitive drug release system comprising a hydrogel loaded with heat-sensitive drug carriers and an electronically controlled flexible heater is also integrated into the dressing to release drugs on demand.". This on-demand treatment is itself observed to inform the changes.

This bandage still smart health connected to the prototype state could cause a leap forward in the treatment of chronic wounds. Such equipment would reduce the number of amputations. Today, dismemberment is a dramatic consequence of the difficulty of following the evolution of injuries.
