Pneumatic Tourniquet

Pneumatic Tourniquet

A pneumatic tourniquet is a medical device used during surgical or medical procedures to temporarily occlude blood flow to a specific area of the body. It consists of an inflatable cuff or band that is wrapped around the limb and connected to a pneumatic pump or control system. The cuff is inflated to control blood flow in the underlying blood vessels, creating a bloodless field for surgery or facilitating certain medical procedures. Pneumatic tourniquets are designed with safety features, such as pressure gauges and quick release valves, to ensure precise control and safe application. They are a valuable tool for surgeons and healthcare professionals to improve surgical outcomes and enhance patient safety during procedures requiring blood flow restriction.



A pneumatic tourniquet is a medical device used to temporarily occlude blood flow to a specific area of the body during surgical or medical procedures. It consists of an inflatable cuff or band that is applied around the limb, and it is connected to a pneumatic pump or system that inflates and deflates the cuff to control the flow of blood in the underlying blood vessels.


  1. Inflatable Cuff: The tourniquet features an inflatable cuff made of a durable and flexible material, such as nylon or silicone, which is wrapped around the limb and secured in place.
  2. Pneumatic Pump: The tourniquet is equipped with a pneumatic pump or control system that allows healthcare professionals to regulate the pressure and inflation of the cuff.
  3. Pressure Gauge: Some tourniquets have a pressure gauge that displays the pressure level applied to the cuff, ensuring accurate and safe inflation.
  4. Quick Release Valve: To ensure rapid deflation and quick release of the pressure on the limb, most pneumatic tourniquets are equipped with a quick release valve.
  5. Safety Features: Pneumatic tourniquets often have safety features, such as audio and visual alarms, to alert healthcare professionals if the pressure reaches potentially unsafe levels.


  1. Surgical Procedures: Pneumatic tourniquets are commonly used during surgical procedures, especially in orthopedic surgeries (e.g., joint replacements) and procedures on limbs where a bloodless surgical field is necessary.
  2. Hemostasis: The tourniquet can be applied in emergency situations or trauma care to control bleeding in extremities before further treatment.
  3. Venous Cannulation: In medical settings, tourniquets are sometimes used to facilitate venous cannulation, making it easier to locate and access veins for intravenous (IV) lines or blood draws.
  4. Blood Collection: Pneumatic tourniquets are also used during blood collection procedures (e.g., venipuncture) to engorge veins, making them easier to locate and access.
  5. Wound Closure: In certain situations, tourniquets may be applied proximal to a wound site to control bleeding and facilitate wound closure.
  6. Limb Blood Flow Monitoring: In specialized medical evaluations, pneumatic tourniquets may be used to assess limb blood flow and vascular function.
