METHOD AND APPARATUS FOR HAND DISINFECTION QUALITY CONTROL

摘要

The invention is based on a method for hand disinfection quality control comprising the steps of providing a hand disinfection medium comprising a light reflecting particles responsive to light mostly outside the visible spectral range of light, applying the hand disinfection medium comprising the light reflecting particles in a prescribed manner for a prescribed time, illuminating the hands disinfected this way with a light source providing light in a spectral range for activating the reflecting particles. The method according to the invention further comprises the steps of providing digital images of the hands from both sides, and evaluating the images by a computer program in order to determine the cleanness of the hands. The invention also relates to an apparatus for implementing the method and assessing hand disinfection quality. The invention uses an apparatus that comprises a rigid case with side walls enclosing a light source for providing light of a predetermined spectral range mostly outside the visible range. The case is further provided with an opening on the front wall for introducing the hands to be exposed to the light of the light source. An imaging device is also attached to the case for taking images of the illuminated hands.
