Definitions

  • the present invention relates to a cleanliness monitoring system and more particularly to a method for monitoring hand cleanliness.
  • the invention also relates to a system and method for assessing the hand cleanliness of individuals.
  • Hand cleanliness is of vital importance in the food industry. Individuals are required not to contaminate food items. Not only does the act of contamination risk illness and even death for the consumer, but also risks legal liability and administrative action against the individual and/or the individual's employer. Hand cleanliness is always an issue when a toilet is used, but it is also an issue when an individual enters the work place from any outside environment or has been involved in any activity which can cause hand toxin or micro-organism contamination.
  • Hand cleanliness is of utmost importance in the preparation of primary food sources (such as in a slaughterhouse), in food factories where pre-prepared food items are prepared, cooked (if necessary) and packed, in kitchens such as in hotels, restaurants and fast food outlets, and in the serving of food items to a customer.
  • Hand cleanliness is also of utmost importance in the medical world. The spread of secondary infections among hospital patients and visitors to clinics or surgeries is often blamed upon the failure of individuals to wash their hands between exposures to different patients. Hand cleanliness is now of even greater importance with the advent of multiple antibiotic resistant microorganisms which place patients' lives at risk. Hand cleanliness is of also of paramount importance in surgery (or dentistry) where the substance of the body is invaded and the chance of transfer of organisms is at its peak in the aseptic regime used. Hand cleanliness can also be of importance in laboratories and in industrial clean facilities such as clean rooms, laboratory and hard disc assembly clean rooms and semiconductor manufacturing facilities.

Abstract

La présente invention concerne un système de surveillance de propreté et un procédé de surveillance de propreté des mains. La propreté des mains est d'une importance vitale en particulier dans les branches d'industrie alimentaire et sanitaire. La contamination présentent des risques de maladie voire des risques mortels pour les consommateurs ou des personnes récupérant d'opération ou de maladie. Les employés, les restaurants, les hôpitaux et les installations de loisir subissent des pressions accrues pour se conformer à la législation plus contraignante. La propreté des mains est toujours un problème lorsqu'on utilise les toilettes, et également un problème lorsqu'une personne entre sur son lieu de travail arrivant d'un environnement extérieur ou ayant eu n'importe quelle activité qui peut entraîner une contamination des mains par des toxines ou par des micro-organismes. Ce système comprend: un révélateur fluorescent, un organe permettant d'identifier l'utilisateur, un organe permettant d'irradier les mains des utilisateurs avec une lumière ultraviolette, un organe permettant d'évaluer la proportion des mains exempte de révélateur et un organe permettant de faire passer ou de refuser l'utilisateur en fonction du fait que de la proportion des mains de l'utilisateur exempte de révélateur est au dessus ou en dessous d'une limite prédéterminée.
