Device Cleaning and Disinfection When There is a Patient Change

When medical devices have already been used with a patient, contamination with human pathogenic germs should be assumed (unless there is evidence to the contrary), and the next patient, user or third party should be protected by appropriate handling and preparation. Therefore, when there is a patient change, people must be protected during the transport and handling of the device and the device must be fully processed, i.e., cleaned and disinfected, by suitably trained personnel before reuse to protect the next patient. The complete processing may only be done by the manufacturer or by a qualified DeVilbiss provider/service technician.

NOTE – When the unit is used as per instructions under normal conditions the interior of the unit is protected from exposure to pathogens by the in-line filter on the collection container, hence no disinfection of internal components is necessary.

NOTE – If the unit is used without an in-line filter then the interior of the unit has been exposed to pathogens and the unit cannot be disinfected.

NOTE – If the following processing of the unit by a qualified DeVilbiss provider/technician is not possible, the unit must not be used by another patient!

DeVilbiss Healthcare recommends that at least the following procedures be carried out by the manufacturer or a qualified third party between uses by different patients.

1. Dispose of all accessory components that are not suitable for reuse, i.e., collection container, filter, tubing and carrying case.
2. With the power switch in the "Off" position, disconnect the DeVilbiss Suction Unit from all external power sources.
3. Visually inspect unit for any damage, missing parts, etc.
4. Wipe the housing with a clean cloth and a commercial (bacterial-germicidal) disinfectant that meets the requirements listed in the NOTE below and is used as per the disinfectant manufacturer's recommended dilution rates and instructions.

CAUTION – Do not submerge in water as this will result in damage to the vacuum pump.

NOTE – Do not use any cleaners or disinfectants that contain ammonia, benzene and/or acetone to clean the unit.
