CONCENTRATOR O2 (DeVilbiss 525KS) 5l

Definition

​A stationary mains electricity (AC-powered) device designed to concentrate oxygen (O2) from ambient air and deliver the concentrated O2, through an attached nasal cannula, to a patient requiring oxygen therapy. It consists of an air compressor, filters, dual chambers, a reservoir and controls. The O2 concentration is variable depending on the flow rate utilized. It is typically wheeled but is designed to be placed in one location.

Quality standards

ISO 80601-2-69, 2020, edition 2, Medical electrical equipment - Part 2-69: Particular requirements for the basic safety and essential performance of oxygen concentrator equipment

Components

  • Casing with vertical layout + handle + 4 wheels, dimensions: 62,2 x 34,2 x 30,4 cm
  • 2 filters (accessible thanks to the removable panel):
    • Foam pre-filter for large particles
    • Case filter for fine dust particles and bacteria
  • Flowmeter adjustable from 1 to 5 litres/min
  • Standard connector nozzle at the O2 outflow (9/16)

Technical specifications

  • Oxygen concentration: 93 % ± 3 % with a flow rate of 1 to 5 litres/min
  • Pressure of oxygen output: 58.6 Kpa ± 10 %
  • Power switch
  • Circuit breaker for re-establishing the current following a power surge
  • Power supply:
    • Voltage: 220-230 V AC, 50 Hz, 1.55Amp
    • Input voltage tolerance: 187-255 V
    • Average consumption: 320 W

3-level alarm system

  • Sound alarm + flashing light "service required" in case of power failure
  • Sound alarm in case the oxygen pressure is below the average (i.e. bended tube, flowmeter < 1 litre/minute or > 5 litres/minute)
  • OSD system = continuous monitoring of O2 concentration:
    • Green light => concentration > 85 %
    • Yellow light => concentration < 85 % (± 2 %)
    • Yellow light + sound alarm => concentration < 75 %

Protection against electric shock

  • Class II double insulation
  • Type B

Supplied with the Article

  • 1 user's and maintenance manual, adapted for MSF
  • 1 technical manual
  • 1 spare filters kit including:
    • 6 foam pre-filters
    • 5 dust and bacteria case filters
    • 5 reusable humidifiers‌

To be Ordered Separately

Don't forget to order the administration devices in sufficient quantities because they are single patient use!

  • oxygen masks for adults and children
  • nasal oxygen cannula for adults and children
  • nasal oxygen cannula for neo-nates and prematures
  • oxygen tubes
  • pediatric flow splitter Sureflow

See related articles at the end of the technical sheet

Instructions for use

Before use, read carefully the user's and maintenance manual (supplied with the concentrator),and the “Respiratory therapy” chapter in the Manual of nursing care procedures, MSF, 2020.

Once the device is turned on, 15 min are necessary to get the maximum level of O2 concentration.

Use of the Airborne module

In case TB patients are suspected: order the Airborne module for the O2 concentrator (avoid cross-contamination)

Use of the humidifier (see separate technical sheet)

The humidification of oxygen is recommended in case of prolonged administration in order to prevent the mucous membranes to dry out.

But if the O2 administration is of short duration (few hours), it is better not to use a humidifier.

5 reusable humidifiers (EEMDCONA003) are supplied with the concentrator.

Use of the paediatric flow splitter 'Sureflow' (see separate technical sheet)

This flow-splitter (EEMDCONE007) is more expensive but more reliable than the previous one.

The paediatric flow splitter allows administering O2 to 2, 3 or 4 children simultaneously and to regulate exactly the flow rate for each child. This should be used with nasal cannula's (nasal prongs) and monitored with a pulse oximeter.

To use humidifiers with this flow splitter you have to order male connectors to screw on the top of humidifiers. To have the same number of connectors as humidifiers to screw: order the HUMIDIFIERS SET (EEMDCONA007) which contains all the necessary accessories for the flow splitter

Precautions for Use

  • Place the concentrator in a well ventilated area, at least 20 cm away from walls or any other object that might prevent free air flow.
  • Protect the concentrator from humidity.
  • Protect the O2 source from any flame or spark. Do not smoke nearby.
  • Do not to use grease on the connections.
  • Do not to use solvent (alcohol, petrol…) on the equipment.

Power supply

The concentrators must work on a stabilized electric supply source.

In case of electric supply problems it is necessary to provide for assistance like a diesel type generator.

Maintenance

The preventive maintenance is simple but must be rigorous (with maintenance logbook):

  • Regularly remove the dust from the casing (to unscrew)
  • Foam pre-filter:
    • clean twice a week
    • replace when damaged (minimum once a year)
  • Case filter: replace every 3 months (in a dusty environment, check every month)
  • Final anti-bacterial filter (inside of the concentrator): replace once a year
  • Humidifier: autoclave sterilization between each patient, change the water daily.

It is recommended to have one oxygen analyzer per mission (see related equipment page) .

MSF requirements

Reliable apparatus, simple to maintain, silent (46 dB), easy to carry (16,3 kg) and mobile thanks to its wheels.

The 5l concentrator is mainly indicated for use with children as it allows a better fine tuning of the oxygen flow below 2 liters. For use in OT and ICU the 10l concentrator is preferred.

SPARE-PARTS

The accessories or spare parts of the different models are not always interchangeables!

Check your concentrator model (at the back of the machine) before ordering spare parts!

The model for which a spare part is intended always appears in the label of the article (515AKS and/or 525KS)

For the 515KS model, the consumables or spare-parts are no longer supplied by the manufacturer: switch to the new model 525KS.
