Novel compact device for clinicians could spot infected wounds faster
Infection can stall the healing of wound or its spread into the body if it isn't treated quickly, putting a patient's health in grave danger. An international team of scientists and clinicians thinks they have the solution: a device run from a smartphone or tablet app that allows advanced imaging of a wound to identify infection. The scientists developed a device called the Swift Ray 1 which can be attached to a smartphone and connected to the Swift Skin and Wound software. This can take medical-grade photographs, infrared thermography images, and bacterial fluorescence images.
To test their device, they recruited 66 wounded patients. Their wounds showed no sign of infection spreading further, did not contain foreign bodies, and had not previously been treated with antibiotics or growth factors. The images were reviewed by a researcher who wasn’t present for the wound care process. Four patterns were identified.
Wounds where the wound was not warmer than healthy skin and no bacterial fluorescence was present were considered ‘non-inflamed’, while wounds that were slightly warmer than healthy skin and had no or slight bacterial fluorescence were considered ‘inflamed’. The last two patterns — wounds that were substantially warmer, with or without bacterial fluorescence — were both designated as ‘infected’, because all the clinicians who had examined these wounds had considered them infected.
