7 SAFETY INSTRUCTIONS
Compressed air connection
The tourniquet device may only be operated with com-
pressed air!
Prior to use
Prior to each use of the tourniquet device, the functional-
ity and tightness of the entire tourniquet system must be
checked. To do so, the cuff must be attached tightly to
a suitable object and filled to the maximum pressure of
500 mmHg. Then the pressure hose must be disconnected
from the device. The indicator eye then changes from the
green indicator "Compressed air" to the white indicator
"Manual". Consistency of pressure must be checked on
the analogue manometer. The pressure drop must not be
greater than 30 mmHg in 5 minutes. If a greater pressure
drop occurs, the device must be inspected (see "Service
Manual, 1 Device Check").
CAUTION
Use the correct cuff size for the respective
•
extremity. The manufacturer offers a com-
plete selection of single cuffs.
If cuffs from other manufacturers are used,
•
compatibility must be ensured.
Damaged cuffs and connections must not be
•
used.
Before connecting the cuff to the tourniquet
•
device, firstly check that the knob has been
reset to zero.
The connecting tubes between the device
•
and cuff must not be disconnected.
While filling the cuff, carry out tactile inspec-
•
tion with your hand to check that the cuff
chamber is being properly filled.
During surgery, the tourniquet system must
•
be continuously checked on the manometer.
The manometer always displays the actual
cuff pressure. Any pressure drop can be read
on the manometer.
Manual operation
Manual operation and operation with the precision
•
pressure regulator knob work independently from each
other. Irrespective of the cuff pressure built up using
the hand inflator, the cuff assumes the value set with
the knob when connected to the central compressed
air supply. This is why the knob's arrow position must
be compared with the mmHg scale on the front of the
device.
When using manual operation, any leaks will not be
•
offset automatically and can only be compensated for
through manual inflation. Regular operation of the
device should therefore occur with compressed air.
Manual operation is only for short-time patient trans-
port or as a backup in the event of compressed air fail-
ure.
