ABSTRACT:
An automated method of disinfecting door handles of units such as disinfecting apparatus. Disinfecting occurs in response to a predetermined function or state, such as the termination of a cleansing operation in a disinfecting apparatus, established time intervals, or a set number of manipulations of the door handle. The door handle may be disinfected by physically moving the handle into the disinfecting apparatus chamber. Alternatively, the handle may be sprayed or impregnated with a disinfecting solution. As another alternative, the door handle may be covered with a sterile, protective film. As a final alternative, the door handle may be disinfected by thermal convection.
