It’s notoriously difficult for doctors to identify a wound that is becoming infected. Clinical signs and symptoms are imprecise and methods of identifying bacteria can be time-consuming and inaccessible, so a diagnosis can be subjective and dependent on clinician experience.
Aug 25 2023Reviewed by Lily Ramsey, LLM But infection can stall healing or 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 which allows advanced imaging of a wound to identify infection.
Shedding light on injuries 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 . Research has demonstrated bacterial imaging helps guide clinicians’ work to remove nonviable tissue, yet it cannot identify infection by itself. Thermography provides insight into the inflammatory and circulatory changes happening under the skin.” The scientists sought to combine these modalities to come up with a method which wouldn’t need multiple expensive devices, would overcome the weaknesses of each imaging method, and could provide an objective measure of wound healing.
A picture of health The images were reviewed by a researcher who wasn’t present for the wound care process. Four patterns were identified. Z
