Use Of Product - GCE COMBILITE Serie Bedienungsanleitung

E RESIDUAL PRESSURE VALVE
GCE combination valve contains a residual pressure valve whose function is to retain a
minimum positive pressure in the gas cylinder to avoid contamination of the cylinder content
by atmospheric air.
F, G FLOW CONTROL HEAD "F" AND FLOW OUTLET "G" OPTION
GCE combination valves can be delivered with a fl ow control head "F". This function is used to
supply gas fl ow rates (l/min) at atmospheric pressure directly to a patient through the fl ow outlet
"G", for instance through a cannula or a facemask.
The fl ow outlet "G" is fi tted with hose fi tting (hose nipple) or a threaded type (for humidifi er for
instance) or with combination of both types.
EN
H PRESSURE OUTLET OR QUICK COUPLER OPTION
The combination valve may be fi tted with a pressure outlet. The pressure outlet is the outlet
direct from the low-pressure part of the valve and it is fi tted with a gas specifi c medical quick
connector also called "quick coupler" (See appendix Nr 2). The user can connect another piece
of equipment to this outlet with a gas specifi c male probe. The quick connector self seals when
the male probe is disconnected. This outlet is for supplying gas at a controlled pressure to
power medical devices, for instance medical ventilator.
EXCESS FLOW DEVICE OPTION
Excess fl ow safety valve can be provided and is located in the valve inlet stem. This provides
extra safety in case of the valve breaking above the valve inlet stem (for instance at cylinder
falling). It has no eff ect on valve function during normal service
Note: Product colour (especially guard, fl ow control knob and shut-off valve) might not
follow any gas colour coding.

6. USE OF PRODUCT

6.1. DISTRIBUTOR OPERATIONS
6.1.1. BEFORE USE
The hereunder operations are performed for instance by the provider (operator) of the device,
trained hospital sta or emergency care sta or trained supplier ensuring delivery of complete
medical package to the user, patient.
VISUAL INSPECTION BEFORE USE
• Check if there is visible damage on the medical gas primary package (including product labels
and marking). If it shows signs of external damages, remove the product from service and
suitably identify its status.
Visually check if the medical gas primary package is contaminated; if needed, apply the
•
cleaning procedure hereunder.
Ensure turning-off at the shut-off valve by turning the hand wheel in a clockwise direction to
•
ZERO position. Do not use excessive force (Maximum recommended closing torque is 2 Nm)
Set fl ow control knob on ZERO position - ensure that the fl ow control knob engages correctly.
•
Remove caps from fl ow outlet and/or pressure outlet. Keep caps in a safe place for reuse
during transport or storage.
LEAK TIGHT CHECK BEFORE USE
• Set fl ow control knob (if any) on ZERO position - ensure the fl ow control knob engages
correctly.
• Open slowly the combination shut-off valve by turning the hand wheel in anticlockwise
direction approx 1 to 1½ turns.
Sudden opening could result in a danger of fi re or explosion arising from oxygen pressure
shocks. Insu cient opening of the shut-o valve could reduce actual fl ow delivered.
