INSTALLATION AND OPERATING INSTRUCTIONS
BIER BLOCK (IVRA) CUFF OPERATION
Review
SINGLE CUFF OPERATION
and
DUAL CUFF OPERATION
.
The following are suggested cuff connections:
•
The proximal cuff connected to the Red Main Cuff ports using the white/red cuff tubing;
•
The distal cuff connected to the Blue Second Cuff ports using the white/blue cuff tubing.
Follow the cuff infl ation sequence adopted by your institution or requested by the surgeon.
When requested, defl ate the fi rst cuff by
TOUCH, SLIDE and HOLDING
the DEFLATE (DEFL) button until the cuff
defl ates.
CAUTION:
In order to defl ate the fi nal cuff, a sequence must be followed to prevent accidental defl ation:
•
TOUCH, SLIDE and HOLD the DEFLATE (DEFL) button on the fi nal cuff.
•
The opposite cuff will alarm “CUFF DEFLATED” to indicate the fi rst cuff is defl ated.
•
A pop-up window will appear on the fi nal cuff’s display area asking for defl ation confi rmation. Touch the
Cancel button to cancel the defl ation or the Okay button
to confi rm the defl ation.
•
The cuff will defl ate.
CAUTION:
•
Defl ation of a cuff is not possible while the other is infl ating.
•
For Bier Block procedures follow the cuff infl ation/ defl ation sequence adopted by your institution or
requested by the surgeon.
ALARM CONDITIONS
There are a number of conditions for which the
A.T.S.
4000TS Tourniquet will produce a visual and/or audible alarm.
The appropriate actions indicated are based on the most probable causes and should only be used as a guide. Other
causes of alarm conditions may indicate a need for other actions.
Most audible alarm tones (non-technical failures) may be silenced for 30 seconds by pressing the ALARM SILENCE
button. The tone will be re-enabled at the end of the silenced period. Pressing the ALARM SILENCE button will cause
the alarm tone to be silenced again.
To minimize nuisance alarms that can be caused by range-of-motion movement of the patient’s limbs, a 1.5-second
delay has been designed into the alarm actuation.
The alarm conditions, indications, and appropriate actions are shown in the
ALARM CONDITIONS
table. In addition
to the alarm conditions shown, it is conceivable that a technical failure could occur for which the indications are
unintelligible and unpredictable. In this situation, the
A.T.S.
4000TS is designed to close the valves, causing the
system to hold cuff pressure and alarm a constant tone. The
A.T.S.
4000TS Tourniquet will also provide Error Code
information for technical failure alarms as shown in the
ERROR CODES
table.
Under certain conditions, such as “SYSTEM FAILURE DETECTED” appears or the information that appears on the
screen is unintelligible, the operator should conclude that a technical failure has occurred, rendering the unit unusable.
The appropriate action is to set the unit to STANDBY by pressing the ON/ STANDBY button.
Since this removes
power from the internal instrument circuitry, all instrument functions, commands to the valves and pump will
cease. This will cause the cuff to hold pressure (in the absence of leaks)
. Clamp the cuff lines with hemostats
and replace the Tourniquet unit.
