Abstract

This invention relates to an electro mechanical-electronic device designed to prevent nosocomical contagions spread by the hands of health care personnel and others due to improper and incomplete hand washing. The device establishes a time reference for the personnel to insure the proper time standards of washing and rinsing hands are attained. Further, the automatic dispensing of a proper quantity of non-contaminated skin degermer and the replacement of natural emolients removed during the washing process is accomplished.
