 Best Tourniquets | 4 Types Of Tourniquets And Uses
A tourniquet is a device used to apply pressure to limbs or extremities to restrict (but not stop) blood flow. It can be used in emergency situations, surgical operations, or post-operative rehabilitation. Furthermore, the blood draw doctor uses a hemostatic tape to evaluate and determine the location of the vein suitable for venipuncture. The correct use of tourniquets will partially prevent venous blood from flowing back to the heart and temporarily collect blood in the veins, so the veins are more prominent and easier to get blood​​. It should be used three to four inches above the needle insertion point and should be kept for no more than one minute to prevent blood concentration.

Simple tourniquets can be made of sticks and ropes (or belts), but because temporary tourniquets are ineffective compared to commercial and professional tourniquets, the use of temporary tourniquets has decreased over time. This may prevent blood flow, but side effects such as soft tissue damage and nerve damage may occur.

Studies have shown that most deaths caused by accidents are the result of bleeding or excessive bleeding. This is because bare hand pressure and bandages can only prevent superficial capillary bleeding. When the bleeding comes from the aorta, the victim will lose too much blood in a short period of time and may die before the ambulance arrives. Therefore, you need an effective kit that can stop bleeding from severe aortic tourniquets.

There are four types of tourniquets: surgical tourniquets, emergency tourniquets, rehabilitation tourniquets, and hemostatic tourniquets used by blood drawers. Evaluation and determination of appropriate venipuncture positions.

Surgical Tourniquets

The silicone ring tourniquet or elastic ring tourniquet is an independent mechanical device and does not require any electricity, wires, or tubes. The hemostat comes in various sizes. In order to determine the correct product size, the patient’s limb circumference at the desired bite position, and their blood pressure should be measured to determine the best model. Once the correct model is selected, two sterile medical personnel will usually be required to use the device. Unlike pneumatic tourniquets, silicone ring tourniquets should be used after the curtain is placed on the patient. This is because the equipment is completely sterile. Most equipment requires two people to operate (except for super large models):


  1. Place the elastic tourniquet on the hand/foot. Please take care to ensure that all fingers/toes are wrapped in the device.
  2. The handle of the tourniquet should be located on the medial-lateral side of the upper limb or the front-back side of the lower limb.
  3. The person using the equipment should start rolling the equipment, and the person in charge of the limbs should keep the limbs straight and maintain axial traction.
  4. Once the desired bite position is reached, the belt can be cut or tied directly under the loop.
  5. A window can be cut or the garter part can be completely removed.
  6. After the operation is completed, the attached cutting card cutting device will be used.

Elastic loop tourniquets follow similar recommendations to pneumatic tourniquets:
  • It should not be used on the patient’s limbs for more than 120 minutes.
  • The tourniquet should not be placed on the ulna/fibular nerve.
  • Silicone ring devices cannot be used for patients with blood problems, such as DVT, edema, etc.
  • Patients with skin lesions or malignant tumors should use this tourniquet.

Silicone ring automatic transfusion tourniquet

The silicone ring automatic transfusion tourniquet (SRT/ATT/EED) or surgical operation automatic transfusion tourniquet (HemaClear) is an easy-to-use, self-contained mechanical tourniquet, consisting of a silicone ring, a garter belt, and a drawstring. As a result, the limb is drawn and occluded within a few seconds after application. The tourniquet can be used for limb surgery in the operating room or as a means of stabilizing the patient in emergency medicine until further treatment is available.

Battle application tourniquet

The combat application tourniquet (CAT) was developed by Ted Westmoreland. The United States and coalition forces use it to provide small effective tourniquets for soldiers in the field. In the UK, the NHS ambulance service and some British fire and rescue services also use it. The device uses a windlass with a locking mechanism and can be installed by itself. CAT has been adopted by military and emergency personnel all over the world.

The Emergency Tourniquets

The emergency tourniquet is a cuff-like device designed to stop severe traumatic bleeding before or during transport to a nursing facility. They wrap around the limbs near the injured site and tighten until they block all blood vessels below. The emergency tourniquet is designed and constructed to allow emergency personnel or injured persons to use it quickly. The correct use of these devices can save lives in harsh conditions with a lower risk of injury. In field trials, the rapid application of emergency tourniquets before the shock can improve survival compared with any other situation where tourniquets are not used later or at all.

Benefits of tourniquet

  • Can be used for amputees. When the risk of bleeding increases, a tourniquet can be used on the amputation limb. Explosions, motor vehicle accidents, or other trauma can cause amputation. They can reduce the chance of hypovolemic shock, which occurs when you lose more than 20% of your blood.
  • Treat multiple casualties. When large-scale casualties occur, such as in terrorist attacks or industrial accidents, tourniquets can be used as the first response treatment. They can quickly stop or slow down bleeding in people with severe limb injuries. This gives emergency personnel more time to treat critical cases, protect the airway, or perform cardiopulmonary resuscitation (CPR).
  • An excellent alternative to direct pressure. When you cannot reach the tourniquet to apply direct pressure, you can use it to prevent bleeding. This may be the only way to control bleeding. This function is very useful when someone is trapped under a boulder with a severely injured limb and cannot get out.

The environment in which you plan to use the tourniquet is very important. Tourniquets have multiple functions, so you need to determine their purpose before buying a tourniquet. There are emergency tourniquets, surgical tourniquets, and rehabilitation tourniquets, although many people will find emergency tourniquets best for most situations.

The best tourniquet can withstand pressure and stay strong after repeated use. In the United States, the FDA requires all tourniquet manufacturers to have a quality management system. The minimum standard is ISO 9001 certification. In addition, the best tourniquet must meet the standards set by the Tactical Combat Casualty Care Committee (CoTCCC). This is an independent organization recognized by the American EMT Association and the American College of Surgeons.
