Description
General
The usher disinfector is designed for cleaning and disinfecting circulation items such
as bedpans and urine bottles. In this context, disinfection means killing all vegetative
bacteria, fungal spores and viruses, but not bacterial spores. A description of the
mechanical design and general functions of the machine is given the instruction manual.
This section contains a general description of the control system and schematic diagrams
of the machine. For detailed information about the software and its settings, see the
chapter entitled “Software description and settings”.
Function
The items are cleaned by ushing with cold and hot water through xed and rotating
nozzles. The water is drawn by a pump from the machine tank and fed to the ushing
housing. The waste outlet of the machine is connected to the normal waste pipe system.
The items are disinfected with steam and then cooled by ushing with water (the cooling
phase can be eliminated by programming the machine accordingly).
