Method and apparatus for hand disinfection quality control

摘要

Method and apparatus for hand disinfection quality control comprising the steps of providing hand disinfection medium comprising 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 disinfected hands with a light source providing light in a spectral range for activating the reflecting particles. The method further comprises providing digital images of the hands from both sides, determining the concentration of reflecting particles, comparing determined concentration values with a predetermined threshold value corresponding to acceptable hand cleanness, and determining whether the quality of disinfection is acceptable or not according to the result of comparison. In the method according to the invention for each person individual threshold value is stored, and the concentration value determined during measuring is compared with the individual threshold value.

主权项

1. An apparatus for assessing hand disinfection quality comprising:
a rigid case with a bottom wall, a top wall, and side walls connected to each other, the rigid case further comprising an opening on a front side for introducing hands of a user previously treated with a disinfection medium comprising light reflecting particles, responsive to light mostly outside a visible spectral range of light, in a prescribed manner and for a prescribed time;wherein the rigid case encloses:
a light source for providing light of a predetermined spectral range for exciting the light reflecting particles on the hands in the rigid case, with an intensity distribution mostly outside the visible range, and an imaging device for taking digital images of the hands, wherein the hands are illuminated from both sides, the imaging device being connected to a computer,
wherein the computer is configured for:
determining a concentration of light reflecting particles,comparing a determined concentration value of light reflecting particles with a predetermined threshold value corresponding to an acceptable hand cleanness value, anddetermining whether a quality of hand disinfection is acceptable or not according to a result of the comparison,wherein the computer is further configured for storing predetermined threshold values for each of individual users, and for comparing the concentration determined with an individual threshold value.
