Cleaning
Cleaning is the physical removal of foreign material, e.g., dust, soil, organic material such as blood,
secretions, excretions and microorganisms. Cleaning generally removes rather than kills microorganisms.
Cleaning is accomplished with water, detergents and mechanical action. Cleaning is an essential
prerequisite for effective disinfection.
Disinfection
Disinfection is the process of eliminating or reducing harmful microorganisms from inanimate objects and
surfaces.
Spaulding classification
The appropriate treatment of medical devices should be based upon how a device is used. Levels of
processing are defined based upon whether a device comes in contact with intact skin, mucous
membranes, or is introduced into the sterile cavity of the body.
According to the Spaulding Classifications, Wrist Array coils and accessories are considered non-Critical
and require intermediate or low-level disinfection for contact with intact skin.
Recommended cleaning agents
•
Cleaning should be performed using a neutral or near neutral pH detergent, such as ENZOL®
Enzymatic Detergent, diluted in utility water (1oz ENZOL® per 1 gallon of water) at room temperature
(15°C-25°C or 59°F-77°F) and applied with a soft damp lint free cloth. Do not apply large amounts of
water.
