The product satisfies the basic requirements set forth in Annex I to Council Directive 93/42/EEC
concerning medical devices (Medical Devices Directive) as well as the applicable national
(German) codes and the Medical Devices Act (MPG) in Germany. This has also been
demonstrated through the application of the corresponding standards which have been
harmonised with Directive 93/42/EEC.
1.5.3 Intended purpose
Name: FINA FLOW
FINA DFLOW
Main function: Designed for measuring the flow and determining the precise
dosage for the supply of oxygen and compressed air. In conjunction
with a hand-held nebuliser, the FINA FLOW is used to provide
metered administration of medication aerosols.
Medical indications /
application:
Specification of the main
function:
Inhalation and insufflation of oxygen within the scope of oxygen
enrichment via an inhalation mask or nose latch for patients who
can breathe independently.
Together with a hand-held nebuliser, administration of water-soluble
medications via an inhalation mask.
Supply of oxygen or compressed air. For oxygen / compressed air
supply, FINA FLOW is connected to a terminal unit for oxygen /
compressed air of a central medical gas supply system with a
pressure of 500 kPa ± 10%. For humidification of oxygen from the
central gas supply system, a humidifier may additionally be
connected. Supply of oxygen to the patient takes place via
connection tubes and an inhalation mask or a nose latch. The

fissures. The gas pressure may cause the flowmeter viewing tube to burst.
Never use detergents that contain alcohol. Observe cleaning and disinfection
standards.
CAUTION!
Property damage!
Using non-colour-fast surgical drapes can cause discolouration of surfaces.
Only use colour-fast surgical drapes.
