How to use Disposable Tourniquet


A disposable tourniquet is a medical device used to temporarily stop the flow of blood through a vein or artery. It is commonly used during medical procedures like blood draws or intravenous (IV) insertions. Here's how to use a disposable tourniquet properly:

Materials Needed:

  • Disposable tourniquet
  • Alcohol swab (optional, for cleaning the skin)
  • Gloves (optional, for infection control)


  1. Prepare the Patient:If you're a healthcare professional, wash your hands or use gloves for infection control. If the patient's skin is visibly dirty or contaminated, clean the skin with an alcohol swab and allow it to dry.

  2. Select the Appropriate Limb:Choose the limb (arm or leg) where the tourniquet will be applied. This depends on the procedure and the accessibility of veins.

  3. Position the Patient:Position the patient comfortably, ensuring the limb is easily accessible and supported. For example, if drawing blood from the arm, have the patient sit with their arm extended and supported.

  4. Apply the Tourniquet:

    • Take the disposable tourniquet out of its packaging. It's typically a strap made of elastic or latex-free material.
    • Hold one end of the tourniquet and wrap it around the patient's limb, a few inches above the intended insertion site (for blood draw or IV).
    • Pull the tourniquet until it is snug but not too tight. The goal is to occlude the blood flow but not cause discomfort or damage to the limb.
  5. Secure the Tourniquet:

    • Some disposable tourniquets have a clasp or clip to secure the strap in place. Attach the clasp to hold the tourniquet's tension.
    • If your tourniquet doesn't have a clasp, you can tie it in a simple knot, ensuring that it is still snug but not excessively tight. The tourniquet should be easily removable.
  6. Check the Limb:

    • Once the tourniquet is secured, check the patient's limb for any signs of discomfort, numbness, or discoloration. If any of these symptoms occur, loosen or remove the tourniquet immediately.
  7. Perform the Medical Procedure:

    • Proceed with the medical procedure, whether it's drawing blood or inserting an IV. The tourniquet will help make the veins more prominent and accessible for the procedure.
  8. Removing the Tourniquet:

    • After the procedure is completed, promptly remove the tourniquet to restore blood flow to the limb. Untie or unclasp the tourniquet and gently roll it off the patient's limb.
  9. Observe the Patient:

    • After removing the tourniquet, observe the patient's limb for any adverse reactions or discomfort. Encourage the patient to move their limb to restore circulation.

Remember, proper application of a disposable tourniquet is crucial to avoid potential complications like nerve damage, tissue injury, or prolonged discomfort. If you're not trained to use a tourniquet, it's best to leave its application to trained healthcare professionals.
