PROVIDER'S NOTES - Cleaning and Disinfection When There is a Patient Change
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 the following described complete processing of the concentrator by an appropriately trained individual is not possible, the device should not be used by another
patient.
NOTE – If preventive maintenance is due at this time, these procedures should be carried out in addition to the servicing procedures.
1 . Use disinfectants safely . Always read the label and product information before use .
2 . Always wear personal protective equipment when performing this procedure . Use suitable gloves and safety glasses . Cover exposed skin on arms to prevent accidental
contact with bleach solution that has been applied to the concentrator .
3 . Dispose of all accessories that are not suitable for reuse . This includes but may not be limited to the oxygen tubing, tubing connectors, nasal cannula and/or mask,
oxygen outlet connector, and humidifier bottle.
4. Clean the exterior of the concentrator with a clean lint-free cloth. Heavy soil should be removed with a clean lint-free cloth dampened with water. A soft bristled brush
dampened with water can be used to remove stubborn soil . Dry the concentrator using a clean lint-free cloth if water was used to remove soil .
5. Use 5.25% chlorine bleach (Clorox Regular Liquid Bleach or equivalent). Mix one (1) part bleach with four (4) parts water in an appropriate clean container. This ratio
produces a one (1) part bleach to five (5) total parts solution (1:5). The total volume (amount) of solution required is determined by the number of concentrators in need
NOTE – An alternate suitable disinfecting agent (e.g. Mikrobac® forte or Terralin® Protect) may also be used. Follow disinfectant manufacturer's
of disinfection .
instructions.
6 . Apply the bleach solution in an even manner to the cabinet and power cord using a clean lint-free cloth . The cloth should be dampened only and not dripping of solution .
Do not use a spray bottle to apply the solution . Do not saturate the device with the solution . Take care that no solution enters the vent areas on the concentrator base or
the Auxiliary O2 fitting area on the back of the unit. Avoid over-saturating the cabinet seams so that no solution residue builds up in these areas. Avoid the caster wells
located on the bottom of the unit .
7 . Exposure time of the disinfectant solution should be 10 minutes minimum to 15 minutes maximum .
8 . After the recommended exposure time, all surfaces of the concentrator should be wiped with a clean lint-free cloth dampened with drinking quality water no warmer than
room temperature. Dry the unit with a dry, clean lint-free cloth. This is to remove residue that may stain or leave a film on the unit, especially after repeated disinfections.
9 . Check the cord, the plug on the back of the device, the power switch, the fuse holder, and the indicator lights for possible damage . Replace all damaged or worn
components .
10. Replace the cabinet air filter on the back of the device.
11. Check the oxygen concentration. If the device is within specification, the extended life intake bacteria filter does not need to be replaced between patients. If the oxygen
concentration is not within specification, the provider should refer to the service manual section on Troubleshooting.
12 . OPTIONAL INSIDE CLEANING: 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 . Close the concentrator .
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.
Disinfection
NOTE – The disinfection process can only be completed by the manufacturer or by an appropriately trained individual.
