Abstract

“Portable, individualized, hand washing agents dispensers are filled and checked out from a control station to healthcare workers and worn by the workers outside their clothing. Unique worker identification signature ID numbers in magnetic counterpart to bar code, and unique dispenser identification signature ID numbers in magnetic counterpart bar code are stored in computer memory. At patient treatment sites, infrared signal transmitters constantly producing a signal, differs at each site for a unique ID number identifying each site. An infrared signal receiver in a dispenser stores in on-board memory the site where the worker dispenses the hand wash agents. Upon return of a dispenser to the control station the amount of agents dispensed by the worker and time, date, and location are recorded. An alternative GPS site identifier is also described.”
