PROVIDER'S NOTES - 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) . 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– If the following described complete processing of the concentrator by a qualified DeVilbiss provider/technician is not possible, the device 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.
NOTE–If preventive maintenance is due at this time, these procedures should be carried out in addition to the servicing procedures.
1.
Dispose of all accessory components that are not suitable for reuse, i.e., particularly the oxygen tubing, the nasal cannula/mask, oxygen outlet connector and humidifier
bottle .
2 .
The concentrator must be disconnected from the power supply for this step: Open the concentrator and remove all dust deposits inside the cabinet with an
appropriate vacuum cleaner .
3 .
Clean and disinfect the power cord and all internal and external parts with a suitable disinfecting agent, e .g ., Microbac Forte or Terralin® .
4 .
Check the cord, the plug on the back of the device, the power switch, the fuse holder and the indicator light for possible damage .
5 .
Replace all damaged or worn components .
6.
Replace the cabinet air filter on the back of the device.
7.
Check the oxygen concentration. If the device is within specifications, the extended life intake bacteria filter does not need to be replaced between patients. If the
concentration is not within specifications, the provider should refer to the service manual section on Troubleshooting.
NOTE– There is no portion of the gas pathways through the concentrator that could be contaminated with body fluids under normal conditions.
The device patient connection may unintentionally become contaminated with expired gases for a single fault condition i .e ., a hose internal to the device becomes
disconnected. This condition will cause no flow out of the device and/or an alarm condition. Should this occur refer to the Service Manual for additional instructions.
