Introduction
1 Introduction
1.1 Intended use
The O2Box Rescue compact is used to transport an oxygen system
and the required accessories. A maximum of 4 patients can be
supplied with oxygen simultaneously on site. The
O2Box Rescue compact is predominantly used at multiple
casualty/victim accident scenes.
1.2 Function
The box is equipped for the transport of two 5 l oxygen cylinders.
It is only ever possible to connect one pressure reducer to the
removable oxygen administrator in the cover of the box.
You can ventilate up to 4 patients with a flow of 1 l/min to 15 l/ml
using the oxygen cylinders in the box.
The connection hose supplied (5 m) has a DIN connector on one
end and a Walther self-sealing adapter on the other.
The oxygen administrator offers the following connection options:
• Walther coupling: connection of a central gas supply with DIN
coupling
• DIN coupling: connection to oxygen supply of external devices
(e.g., MEDUMAT Standard2ventilator)

WM 66421 04/2015

Hygienic reprocessing
5 Hygienic reprocessing
5.1 General instructions
• Use suitable gloves for disinfection work (e.g., household or
disposable gloves).
• Please refer to the instructions for use supplied with the
disinfectant used.
• Recommendation: terralin®protect for wipe disinfection
5.2 Intervals
Reprocess the device hygienically after every use.
5.3 Hygienic reprocessing of the device
1. Remove the oxygen cylinders from the box.
Risk of explosion if disinfectants containing alcohol or grease
are used for wipe disinfection!
Disinfectants containing alcohol or grease react with oxygen to
create a flammable mixture and can result in explosions and injury
to the user and patient.
When wiping the pressure reducer and the oxygen
administrator with disinfectant, do not use disinfectants
containing alcohol or grease.
Risk of injury due to ingress of liquids!
Liquids entering the oxygen administrator and pressure hoses
(e.g., disinfectants) can injure the patient and damage
components.
Never immerse components in liquids. Wipe them down
carefully with a moist cloth.

6.1 Intervals
Carry out a function check at the following intervals:
• Before each use
• After each disassembly
• Every 6 months
6.2 Checking the box
1. Carry out a visual inspection.
Requirement:
• The corners and handle are undamaged.
• The locks can be opened easily.
• The hinges open smoothly and are correctly attached.
• The foam is not impaired in its function.
• The cover holder is undamaged and the hinge of the cover
holder opens smoothly.
• The cover holder clicks into both positions (on the box and
on the cover) securely.
2. If one of the requirements is not fulfilled: replace defective
components or send the box to the manufacturer,
WEINMANN Emergency, for repair.
Result The box has been checked.

Function check
6.3 Checking the oxygen administrator
1. Check the oxygen administrator for visible mechanical
damage.
2. To check the flow: connect the oxygen administrator with the
pressure hose to the pressure reducer of an oxygen cylinder.
3. Set all the locking buttons on the oxygen administrator to 0.
The valves on the oxygen administrator and thus the system
behind the pressure reducer are blocked.
4. Check that the screwed unions and hose connections are
secure.
5. If necessary: tighten the screwed unions by hand.
6. Open the valve of the oxygen cylinder slowly.
7. Read off the cylinder pressure on the contents gauge of the
pressure reducer.
8. When cylinder pressure is < 50 bar: change the oxygen
cylinder.
9. Use the locking buttons to set all of the locking positions in
succession.
Requirement: The flow at the oxygen outlet must increase as
per the locking position (increasing hissing noise).
10. To check for leaks: set all the locking buttons to 0.
11. Close the valve on the oxygen cylinder.
Risk of injury from damaged oxygen administrator!
A damaged oxygen administrator does not provide sufficient
oxygen for ventilation. This can injure the patient.
Only use the box if all the locking buttons on the oxygen
administrator are undamaged.
Cylinder pressure = 200 bar: oxygen cylinder is full
Cylinder pressure = 100 bar: oxygen cylinder is half-full
The oxygen administrator is not a shut-off valve. The only way to
prevent oxygen from escaping from the system is to keep the valve
on the oxygen cylinder closed.

18 EN O2Box Rescue compact
WM 66421 04/2015
Function check
12. Watch the needle on the contents gauge of the pressure
reducer for approx. 1 minute.
Requirement: The needle must remain still.
13. Set a locking button to 0until the system is depressurized.
14. If a requirement is not fulfilled: contact
WEINMANN Emergency or a technician authorized by
WEINMANN Emergency.
Result The oxygen administrator has been checked.
6.4 Checking the fixation of the oxygen
administrator
1. Insert the oxygen administrator in the cover of the box.
2. Push the locking levers outwards until the locking mechanism
noticeably snaps into place.
Requirement: It must not be possible to move the oxygen
administrator.
3. If the locking levers do not function perfectly: replace the
equipment rail adapters.
Result The fixation has been checked.
6.5 Checking the pressure reducer
Observe the instructions for use of the OXYWAY pressure reducer.

OXYWAY Click oxygen administrator.
• Observe the instructions for use of the OXYWAY pressure
reducer.
8Storage
Observe the permissible ambient conditions (see “10.1.1 Technical
data for box”, page20).
