demonstrated through the application of the corresponding standards which have been
harmonised with Directive 93/42/EEC.
1.5.3 Treatment system as per Article 12
The product consists of several components which together comprise one treatment system as
per Article 12 of the Medical Devices Directive 93/42/EEC (Paragraph 10 of the Medical Devices
Act).
The emergency oxygen unit consists of the following components:
• Pressure regulator (REF 5752 5545)

• AS aspiration (REF 5752 4681)
Introduction
Basic requirements

1.5.4 Intended purpose
Name: Emergency oxygen unit
Main function: Treatment system consisting of several components for
Medical indications /
application:
Specification of the main
function:
administration of oxygen and for bronchial aspiration
Supply of patients with medical oxygen and bronchial aspiration if a
central gas supply is not available (e.g. interhospital transport)
The emergency oxygen unit is a treatment system as per Article 12
of the Medical Devices Directive 93/42/EEC (Paragraph 10 of the
Medical Devices Act).
The components are listed in the following chapter of these
operating instructions.
The carrying board provides a basis for a 2 or 3 l oxygen cylinder. A
pressure reducer is connected to the oxygen cylinder and reduces
the pressure to the usual pressure of central gas supply systems.
An integrated flowmeter in the pressure reducer can be used for
inhalation or insufflation of oxygen within the scope of oxygen
enrichment for patients breathing by themselves. In the coupling
DIN of the pressure regulator a fine regulator oxygen can be
inserted. A gas-jet pump can be connected to the outlet of the fine
regulator, converting the oxygen into vacuum via Venturi principle.
The application set aspiration consists of a septic fluid jar with lid
for bronchial aspiration. The permissible pressure in the oxygen
cylinder is 200 bar.
User profile: Doctor, medically trained staff
Patient groups: Patients of all ages

Function test
4 Operation
4.1 Function test
Prior to using the system, the operator must check that the product is fully functional and in good
condition. Prior to each use, carry out the following functionality checks:
Pressure regulator
• State of manual tightening
• State of seal in cap nut
• Ease of movement at the connection threads (difficulty of movement is an indication of damage or soiling to the threads),
• Damage to supply tubes
• Airtightness
• Intact connection thread for accessories
NOTE
Unscrew manual tightening only after pressure has been fully released from the
pressure regulator. First, close the valve on the oxygen cylinder; then release the
pressure on the click-stop flowmeter.
Suction unit
• Damage of seal rims of float in the overflow protection device
• Any cracks in septic fluid jar
• Splintering at the contact surfaces of the septic fluid jar
• Damage to seal of the septic fluid jar cap
• Cracked or hardened connection tubes
• State of seal in cap nut of gas-jet pump
• Free movement of control valve of fine regulator for gas-jet pump
Oxygen cylinder
• Sufficient filling level
4.2 Check the filling level of the oxygen cylinder
NOTE
Check airtightness of all accessory connections before beginning treatment.
Manually retighten connecting nuts as necessary and readjust to the amount of
oxygen required.
The duration of use in treatment depends on the filling level of the oxygen cylinder. The filling
level may be checked as follows:
Cylinder pressure (kPa) * cylinder volume (V) / O2 dosage (l/min)
Example of calculation:
• Cylinder pressure = 200 kPa
• Cylinder volume = 2 l
• O2 dosage = 4 (l/min)
• 200 * 2 / 4 = 100 min
The cylinder contents will last for approximately 1.5 hours.
