now patients can follow the healing progress of their wounds

To have a wound that does not heal is the wound. This affects more than two million people and costs nearly three billion euros to the French in consultations and care, and the hospital tension is growing. It is by this observation that Matis Ringdal, a biologist by training, decided to launch in 2019 Pixacare, a tool to facilitate the monitoring of chronic wounds for professionals. At the microphone of France moves, he came to explain the principle of his innovation. “The idea came during a health hackathon, that is to say an innovation competition which brought together health professionals, to provide solutions to problems encountered in the environment”, begins- he explained.

Better follow-up of patients by professionals

The principle: use your smartphone as a medical tool. The doctors will be able to take pictures of the wounds, fill in certain information and, thanks to an algorithm, generate new information on the wounds for a complete follow-up. Beyond knowing a patient’s file better, having this information on the same application helps to avoid complications.

“You will have a hospital doctor, then you will have a surgeon. You will also then have home nurses. This follow-up is not standardized, it is not structured. So with this tool, all health professionals will be able to follow the evolution of the scar and therefore react as soon as they see an infection, for example, as soon as they see a complication and allow, for example, collaboration between the City and the hospital”, explains the CEO of Pixacare .

And a better understanding of injuries

According to the biologist, it is complicated to calculate the size of a wound and therefore the potential risks. “We have developed algorithms which allow, from the photo, the wound and a patented technology which allows in particular to normalize the image, to ensure that as soon as we take the photo of the wound, we automatically calculates its size and automatically describes its content.”

This technology is already used in twenty health establishments, including five prestigious university hospitals such as the CHU of Lille, the CHU of Brest or the hospitals of Strasbourg, which use it in particular to save medical time. “We have already produced a first scientific publication which shows that the time is reduced to three minutes per consultation, so doctors can do more than 20 consultations a day. This can represent, for some surgeons in particular, more than an hour of gain time per day”, reveals Matis Ringdal.

In addition, the established photo library could become over time a real tool for the development of knowledge on the follow-up of wounds and the training of future doctors.
