GENERAL INFORMATION GENERAL INFORMATION APPLICATION SPECIFICATION The application specification for the A.T.S. 5000 including characteristics related to the use of the device, intended use, intended part of the body, intended user profile, intended conditions of use and operating principles is contained in this manual.
INTENDED USE The A.T.S. 5000 Tourniquet Device is intended to be used by perioperative nurses, surgeons, and anesthesiologists, to temporarily occlude blood flow in a patient’s extremities during surgical procedures on those extremities. Tourniquets have been found useful in producing a bloodless operation field in surgical procedures involving the extremities including: •
Reduction of certain fractures
•
Kirschner wire removal
•
Subcutaneous fasciotomy
•
Nerve injuries
•
Bone grafts
•
Total wrist joint replacement
•
Knee joint replacements
•
Amputations
•
Tumor and cyst excisions
•
Tendon repair
•
Replacement of joints in the fingers
•
Replantations
WARNING: •
Do not use tourniquet cuffs to control the distal flow of CO2 or any other gases used as a distention media. Tourniquet cuffs have not been evaluated for safety or effectiveness in controlling gas flow beyond the surgical site during arthroscopic insufflation procedures. Possible effects of using a tourniquet cuff in this manner include serious subcutaneous emphysema proximal to the cuff.
•
Do not use the tourniquet device as a source of pressure for infusion of IV fluids as this could result in either excessive infusion pressures leading to patient injury or burst IV fluid bags.
CONTRAINDICATIONS The medical literature lists the following as possible contraindications: •
Open fractures of the leg
•
Post-traumatic lengthy hand reconstruction
•
Severe crushing injuries
•
Elbow surgery (where there is excess swelling)
•
Severe Hypertension
•
Diabetes mellitus
•
Skin grafts in which all bleeding points must be readily distinguished
•
Compromised vascular circulation, e.g. peripheral artery disease
•
The presence of sickle cell disease, which is a relative contraindication (See PRECAUTIONS IN USE)
Page 4
GENERAL INFORMATION CAUTION: •
In every case, the final decision whether to use a tourniquet rests with the attending physician.
•
A tourniquet should also be avoided in patients who are undergoing secondary or delayed procedures after immobilization.
•
Healthcare professionals should always have a secondary means available to control blood loss in the event of sudden or unexpected rapid deflation of the Tourniquet.
•
Certain physiologic or anatomical conditions may prevent the A.T.S. 5000 from making a determination of LOP, in which case the device will display an appropriate message and will terminate the attempt to measure LOP. In that event, the physician’s judgment should be used to set tourniquet pressure in the absence of the LOP feature.
PRECAUTIONS IN USE •
Not for use in an oxygen-rich environment with an oxygen concentration greater than 25% for ambient pressures up to 110 kPa or in which the partial pressure of oxygen is greater than 27.5 kPa at ambient pressures exceeding 110 kPa.
•
Under normal operation, the A.T.S. 5000 runs on ~ AC Power Mains via its power cord. The backup battery is intended for emergency power or transport.
•
The Tourniquet Device must be kept well calibrated and in operable condition (see Maintenance section for calibration instructions). Accessories should be checked regularly for leaks and other defects (see Maintenance section for cuff leak testing instructions).
•
The Tourniquet cuff must never be punctured; therefore, towel clips used near the system must be handled with special care. Cuffs with inner rubber bladders must be completely enclosed by the outer envelope to preclude ballooning and possible rupture of the bladder. Cleaning and assembly instructions of the cuff manufacturer should be followed carefully.
•
Do not use an elastic bandage for exsanguination in cases where this will cause bacteria, exotoxins, or malignant cells to spread to the general circulation, or where it could dislodge thromboemboli that may have formed in the vessels.
•
The Tourniquet cuff must be applied in the proper location on the limb, for a “safe” period of time, and within an appropriate pressure range. Never apply a Tourniquet over the area of the peroneal nerve or over the knee or ankle. Do not readjust an already inflated cuff by rotating it because this produces shearing forces which may damage the underlying tissue.
•
Prolonged ischemia may lead to temporary or permanent damage to tissues, blood vessels, and nerves. Tourniquet paralysis may result from excessive pressure. Insufficient pressure may result in passive congestion of the limb with possible irreversible functional loss. Prolonged Tourniquet time can also produce changes in the coagulability of the blood with increased clotting time.
•
Inflation should be done rapidly to occlude arteries and veins as near to simultaneously as possible.
•
Careful and complete exsanguination reportedly prolongs pain-free Tourniquet time and improves the quality of Intravenous Regional Anesthesia (IVRA), also known as Bier Block anesthesia. In the presence of infection and painful fractures, after the patient has been in a cast, and in amputations because of malignant tumors, exsanguination before Tourniquet application may be done without the use of an elastic bandage by elevating the limb for 3 to 5 minutes.
•
In case of failure, the Tourniquet cuff must be fully deflated and the limb exsanguinated again before reinflation. Reinflation over blood-filled vasculature may lead to intravascular thrombosis.
•
Tourniquet users must be familiar with the inflation-deflation sequence when using a dual-cuff Tourniquet or two Tourniquet cuffs together for IVRA (Bier Block anesthesia), so that the incorrect Tourniquet will not be released accidentally.
Page 5
GENERAL INFORMATION •
Test for hemoglobin type and level before using a Tourniquet on patients with sickle-cell anemia. When the Tourniquet is used for these patients, the limb should be carefully exsanguinated and the PO2 and pH should be closely monitored.
•
Select the proper cuff size to allow for an overlap of about 3 to 6 in. (7.6–15 cm) with a cylindrical cuff. Too much overlap may cause cuff rolling and telescoping, and may lead to undesired pressure distribution on the limb. A larger overlap range is acceptable for a contour-shaped cuff. The skin under the Tourniquet cuff must be protected from mechanical injury by smooth, wrinkle-free application of the cuff. If the Tourniquet cuff is applied over any material that may shed loose fibers (such as Webril), the fibers may become embedded in the contact closures and reduce their effectiveness. As an under padding, a section of stockinette may be used. The deflated cuff and any underlying bandage or protective sleeve should be completely removed as soon as tourniquet pressure is released. Even the slightest impedance of venous return may lead to congestion and pooling of blood in the operative field. After the cuff has been fully deflated and removed from the patient, the device can be set to STANDBY (power OFF).
•
If skin preparations are used preoperatively, they should not be allowed to flow and collect under the cuff where they may cause chemical burns.
•
Whenever the Tourniquet cuff pressure is released, the wound should be protected from blood surging back by applying pressure dressings and, if necessary, elevating the limb. Transient pain upon Tourniquet pressure release can be lessened by elevation of the limb. If full color does not return within 3 to 4 minutes after release, the limb should be placed in a position slightly below body level.
•
Whenever IVRA (Bier Block anesthesia) is used, it is recommended that the Tourniquet remain inflated for at least 20 minutes from the time of injection.
WARNING: Cuffs will not deflate in STANDBY mode. Ensure cuffs are fully deflated before setting the device to STANDBY.
ADVERSE EFFECTS A dull aching pain (Tourniquet pain) may develop throughout the limb following use. Pathophysiologic changes due to pressure, hypoxia, hypercarbia and acidosis of the tissues occur and become significant after about 1 1/2 hours of Tourniquet use. Symptoms of Tourniquet paralysis are motor paralysis and loss of sense of touch, pressure, and proprioceptive responses. Intraoperative bleeding may be caused by the following: •
The slight impeding effect exerted by an unpressurized cuff (and its padding, if used), which prevents venous return at the beginning of the operation.
•
Blood remaining in the limb because of insufficient exsanguination.
•
Inadequate Tourniquet pressure (between systolic and diastolic blood pressure of the patient), or slow inflation and deflation, all of which allow arterial blood to enter while preventing venous return.
•
Blood entering through the nutrient vessels of the long bones, such as the humerus.

INSTALLATION AND OPERATING INSTRUCTIONS device 10 hours before initial setup, including calibration checking procedures, initial checks, tests and any institution-performed biomedical evaluations. Ensure that the device is positioned in a location that minimizes glare from overhead lights and other obstructions. The device may be mounted to an I.V. Pole/Tourniquet Stand/OR Boom, or placed on a table or shelf. If the device is placed on a table or shelf, ensure the surface is level prior to use to prevent movement due to vibration. CAUTION: Before transporting the device, ensure all cables and hoses are managed to reduce trip hazards.
TESTS AND CHECKS The device shall produce the results explained in the following steps exactly as indicated. Failure to do so indicates that a problem may exist, and the device is not to be used until necessary repair or calibration has been made. Refer to Alarm Conditions or Maintenance sections as appropriate.
AUTOMATIC DIAGNOSTIC AND CALIBRATION CHECK These automatic checks verify certain System Functions through diagnostics and calibration to system standards. 1. Connect the power plug of the device to a properly polarized and grounded power source with voltage and frequency characteristics compatible with the Specifications and Performance Characteristics section listed above. Observe that the green ~ AC Power Mains indicator light turns on and illuminates the Power Button in STANDBY mode. 2. Turn the device ON by pressing the Power Button and observe the following: •
The device displays “A.T.S. 5000” text. An animated “Z” icon will appear on the LCD display. The LEDs around the connector ports will light up indicating progress.
•
The device displays “DIAGNOSTIC” indicating self-testing specific system hardware and software. If all tests pass successfully, the “DIAGNOSTICS OKAY” message will appear.
•
The “DIAGNOSTICS OKAY” message is replaced by “CALIBRATION” during the calibration check.
•
Once the calibration check is complete, the on-screen text changes to “CALIBRATION OKAY”. Then the text disappears, and the circle icon minimizes.
CAUTION: The A.T.S. 5000 will automatically perform an internal Diagnostic and Calibration check when powered ON. Setting the device to STANDBY and powering back ON between cases will allow the device to re-perform the automatic Diagnostic and Calibration check. •
After the startup routine is complete, the default Graphical User Interface (GUI) appears:
•
“0” is indicated in the PRESSURE and TIME Tiles of both the Main and Second displays.
•
The default pressure is shown on both PRESSURE Tiles. The default pressure is pre-set to 250 mmHg. This setting may be changed as desired in the Protocols menu.
•
The default time is shown on both TIME Tiles. The default time is pre-set to 60 minutes. This setting may be changed as desired in the Protocols menu.
CAUTION: •
If “CALIBRATION ERROR” is displayed, refer to the Calibration Error at Power-On section within the Maintenance section.
•
If a number other than zero is indicated in the PRESSURE display when a cuff is not connected, the device should be calibrated by a qualified biomedical engineer or other person thoroughly familiar with electronic medical devices via the Calibration section within the Maintenance section.
