E. Sterile syringes and needles
10-20 ml syringe is used when veins are weak and may collapse. Transfer
safety devices are required when using the syringe method.
F. Tourniquets:
• 3” to 4” above the site of venipuncture
• Slows venous blood flow causing the veins to bulge thereby making it
easier to locate and palpate the veins.
• Blood pressure cuffs may also be used as a tourniquet, but is not
common
• The tourniquet should not stay on longer than 1 minute. If the tourniquet
is left on longer than 2 minutes it causes hemoconcentration of the
