Were you able to thoroughly disinfect the entire area?Evaluation of disinfection activities using thermal camera

We propose a visualization system to verify wipe disinfection status on surfaces such as a safety cabinet. In wipe disinfection, disinfectants such as alcohol are sprayed onto the surface and wiped off with sufficient pressure to remove cells and bacteria. Our proposed method evaluates wipe disinfection process using a thermal camera and pressure sensors. The thermal camera captures sprayed disinfectant on surfaces by detecting a reduction in surface temperature due to its evaporation. The pressure sensor measures the applied pressure during wiping. By combining these data, our system visualizes the area that was sufficiently sprayed with disinfectant and wiped with enough pressure. In medical situations, including regenerative treatment, complete disinfection of the entire area is essential. However, wipe disinfection has been performed according to the manual, and methods for verifying disinfection results are limited. In contrast, our system enables users to improve disinfection treatment by understanding disinfection results and to achieve an environment where users can work safely to disinfect. We aim to contribute to improving medical safety and efficiency.
