System Overview The dual channel tourniquet system allows for the connection of two cuffs. The pressure value and elapsed inflation time value of each cuff are displayed, monitored, and controlled independently within two separate channel areas. The system maintains real-time cuff pressure within normal operating parameters relative to the set target pressure value. Variations in pressure are detected and adjusted to the set target pressure value within two/tenths of a second. These automatic adjustment responses are sequenced to deliver optimal, progressive pressure compensation without causing overpressure fluctuations, frequent pressure adjustments or false triggering due to transient pressure variations. This functionality enhances cuff pressure maintenance and addresses the unique pressure dynamics associated with various size cuffs and their relatively low inflatable volumes. Cuff pressure changes may be caused by limb extension and contraction and initial cuff conformity and tissue compression. After initial cuff inflation, minor changes in pressure above or below the set target pressure value may occur. Intraoperative limb manipulation may cause the cuff to induce a momentarily, minor high and/or low-pressure fluctuation. A momentary decrease in limb volume, associated with extension motions may cause the system to sense low pressure, as the cuff’s compressible target briefly becomes smaller. Momentary increases in pressure may also occur due to external compression of the cuff during limb contraction, which temporarily causes the limb to assume a larger compressible volume. All of these pressure fluctuations are compensated for by the system and adjusted to the set target pressure automatically. Cuff pressure conditions determined to be outside normal operating parameters will trigger an audible and visual alarm requiring immediate action. Such pressure conditions may be caused by a leaking or damaged cuff, a leaking cuff O-ring, a loose Luer connection, or a leaking fill line.

Instructions (continued) To Connect a Cuff 1. Ensure the READY icon and DEFAULT DISPLAY icon appear on the information screen. 2. If the default time and pressure settings are acceptable, connect a fill line to the pump. If the time and pressure settings need to be changed, see the To Change the Procedure Time and Target Pressure Values section. 3. Position the cuff on the patient’s limb. WARNING: Connect the fill line connector of the pump to the tourniquet cuff only. Fill line extension tubing and/or an adapter may be used between the fill line connector of the pump and the tourniquet cuff. See the Definitions - Symbols section. 4. Connect the cuff to the fill line connector. 5. Inflate and deflate the cuff as required. See the To Inflate a Cuff section.
To Inflate a Cuff WARNINGS: • ALWAYS operate the equipment within the specified environmental condition values. See the Specifications section. • Verify the tourniquet pump is connected to the tourniquet cuff only. • ALWAYS monitor the cuff pressure and application time throughout a surgical procedure. DO NOT apply excessive cuff pressure. DO NOT use a cuff for an excessive amount of time. Failure to comply may result in patient injury, including vascular complications, neuromuscular or neurological injuries, tourniquet pain, ischemia, venous emboli or thromboembolism, blood vessel trauma, reperfusion problems and arterial occlusion, mild, aching pain in the limb, stiffness, weakness, reactive hyperemia, and skin discoloration. • NEVER turn OFF the pump while the cuff(s) are inflated. Failure to comply will cause the cuffs to deflate and may result in patient injury.
www.stryker.com
WARNINGS: • Pay particular attention to excessive sound associated with frequent pump activity. Any pressure loss will cause the system to compensate for the decreased pressure. However, the system may eventually fail to maintain cuff pressure if the pressure loss begins to increase significantly. See the Troubleshooting section. • ALWAYS resolve an alarm condition before continuing to use the pump. An alert triangle, a flashing time or pressure value, or a wrench icon with a service code indicates an alarm condition. See the Troubleshooting section. • If a pump malfunction occurs due to a loss of both AC power and internal battery power, an inflated cuff will remain inflated. Deflate the cuff by manually disconnecting the cuff. 1. Press the INFLATE button to inflate the selected cuff. 2. Ensure the selected cuff inflates to the target pressure value and the time value accumulates the elapsed time of cuff inflation. 3. Monitor and manage the pressure and elapsed time settings. See the To Change the Procedure Time and Target Pressure Values section as required. NOTE: If a cuff cannot reach or maintain the target pressure value during initial inflation, discontinue using the cuff. See the To Switch (or Backup) a Single Cuff section. 4. When the target elapsed cuff time is reached, perform one of the options: • Option 1 - Press the DEFLATE button to deflate the selected cuff. See the To Deflate a Cuff section for details. NOTES: • If necessary, you may then press the INFLATE button to re-inflate the cuff to the highest pressure used during the procedure. The elapsed cuff time will start again and continue to accumulate elapsed cuff time. • The pump will not deflate the cuff automatically when the target time is reached. You must press the DEFLATE button to deflate the selected cuff.

NOTES: • When the cuff pressure value reaches zero, the pressure value and pressure gauge icon are not present on the information screen. The total elapsed cuff time remains on the information screen. • In the deflated (inactive) state, the pump will continue to monitor ambient air pressure. The pump will exhaust any ambient pressure due to cuff or patient movement, automatically, before cuff removal. • The IVRA LOCK/UNLOCK CONTROL button may be used to prevent accidental cuff deflation during a Bier Block procedure or the management of two cuffs involved in a bilateral procedure. See the To Perform a Bier Block Procedure section for details.

To Print the Procedure Summary Report (optional) NOTES: • Procedure summary information is saved and retained in the pump even if power is removed or the internal battery is fully discharged. • Each time a new procedure is initiated, the previous summary information is replaced by the new information. • Previous summary information may be replaced as follows: (1) pressing the DEFAULT DISPLAY button followed by pressing the INFLATE button and (2) turning the pump OFF and ON followed by pressing the INFLATE button. 1. Make sure the optional report printer is connected to the pump. See the instructions for use supplied with the report printer. 2. Make sure the report printer is loaded with the proper self-adhesive labels and ready for use. See the instruction for use supplied with the report printer. 3. Press the PRINT button on the pump. 4. Apply the self-adhesive label to the patient record or chart according to current local guidelines.
To Perform a Bier Block Procedure WARNINGS: • ALWAYS follow current hospital protocol governing the safe and effective use of a Bier Block procedure. • DO NOT apply excessive cuff pressure or apply the cuff(s) for an excessive amount of time during a Bier Block procedure. Failure to comply may result in patient injury or death.

Instructions To Perform a Bier Block Procedure (continued)
To Switch (or Backup) a Bier Block Cuff
NOTES: • The pump will support the connection of a Bier Block cuff to either cuff channel one or two. • Pressing the INFLATE button will interrupt a cuff deflation instantly or return cuff pressure to the highest value used during the preceding procedure. • The IVRA LOCK/UNLOCK CONTROL button may be activated (locked) either before or after inflation. 1. Press the IVRA LOCK/UNLOCK CONTROL button to lock the IVRA control and prevent the accidental deflation of the cuff. Ensure the IVRA LOCK icon is displayed on the information screen. NOTE: If a cuff cannot reach or maintain the target pressure value during initial inflation, discontinue using the cuff. See the To Switch (or Backup) a Bier Block Cuff section. 2. Sequence the inflation and deflation of the Bier block cuffs according to current local guidelines governing the performance of a Bier Block procedure. 3. After the sequencing is complete, deflate the Bier Block cuffs using one of the options: • Option 1 - Press the IVRA LOCK/UNLOCK CONTROL button to unlock the IVRA control and allow the deflation of the cuff. • Option 2 - Deflate the cuff pressure incrementally. See the To Change the Procedure Time and Target Pressure Values section. After incremental deflation of the cuff is complete, press the IVRA LOCK/ UNLOCK CONTROL button to unlock the control and allow full deflation of the cuff.
NOTES: • If the primary cuff cannot reach or maintain the target pressure value during initial inflation and before anesthetic injection, discontinue using the cuff. • If, before deflation of the primary cuff, the secondary cuff cannot reach or maintain the target pressure value, use this procedure to backup the primary cuff. 1. Ensure the cuff and all pneumatic connections are leak-free and secure. 2. Clamp and close the fill line of the inflated primary cuff to retain cuff pressure. 3. Disconnect the fill line of the primary cuff from the pump. NOTE: A pressure alarm condition will occur. 4. Connect the fill line of the secondary cuff to the fill line connector of the primary cuff. 5. After confirming the second cuff reaches the target pressure value, release the clamped primary cuff. 6. Adjust the cuff time and target pressure values as required. See the To Change the Procedure Time and Target Pressure Values section.
