GENERAL INFORMATION

GENERAL INFORMATION

APPLICATION SPECIFICATION

The application specification for the A.T.S. 4000TS including characteristics related to the use of the device, intended

use, intended patient population, 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. 4000TS Tourniquet System is intended to be used by qualified medical professionals 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.

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 is a relative

contraindication (See PRECAUTIONS IN USE).

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.

•

Certain physiologic or anatomical conditions, including small fingers and toes of infants and children, may

prevent the A.T.S. 4000TS from making a determination of LOP, in which case the instrument 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.

Page 4

Page 6

GENERAL INFORMATION

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 the partial pressure of oxygen is greater than 27.5 kPa at ambient pressures exceeding 110 kPa.

•

Normal operation has the A.T.S. 4000TS running on ~ AC Power Mains via its power cord. The backup battery is

intended for emergency power or transport.

•

The Tourniquet system must be kept well calibrated and in operable condition. Accessories should be checked

regularly for leaks and other defects.

•

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 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 wrong Tourniquet will not be released

accidentally.

•

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). Too much overlap may cause cuff

rolling and telescoping, and may lead to undesired pressure distribution on the limb. 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. After the cuff has been fully deflated and removed from the patient, the

unit can be set to STANDBY. Even the slightest impedance of venous return may lead to congestion and pooling

of blood in the operative field.

•

If skin preparations are used preoperatively, they should not be allowed to flow and collect under the cuff where

they may cause chemical burns.

Page 5

Page 7

GENERAL INFORMATION

•

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 unit 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 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.
