Hand-in-Scan is a device with an identification system that is able to track individual’s hand hygiene habits to provide continuous, more comprehensive monitoring of the staff’s hand hygiene trends throughout an organisation. Using Hand-in-Scan, it is possible to give a scientifically thorough assessment of each shift, staff or age group’s hand hygiene behavioural patterns. The necessity of Hand-in-Scan is supported by sad statistical data showing that perfect hygiene can still be a problem. Even in developed countries, an average of 7% of patients acquire secondary infections from the unsanitised hands of medical professionals. Hand-in-Scan is developed to address this issue. The device uses ultraviolet light, digital imaging and artificial intelligence software methods to distinguish between sanitised and infected areas after hand washing. The users perform hand washing with an UV-marked substance, which appears brighter on surfaces sufficiently treated with the alcoholic disinfectant. Inside the body of the device, wide-angle cameras take pictures of the hands in the UV-lighted box. Results are processed and shown on the screen. Later data can be accessed and easily evaluated. Hand-in-Scan’s design is sculpted by the aesthetics of simplicity and functionality. It is easy to clean and keep clean, it can be wall-mounted and it is robust enough to take thousands of scans each day. The casing is made of anodised aluminium. The design team, Flying Objects, also created a user interface that is simple and easy to use without touching the device, yet still being informative.
