transport the blood from the vein into the collection tube when penetrated. Using this method helps to obtain multiple tubes of blood with one venipuncture stick
Evacuated System - Vacutainer needles are typically
20 to 22 gauge with a needle length ¾ in to 1 ½ inches
What is the most commonly used system?
evaluated system
Winged infusion set consists of
flexible wings attached to a needle with 5 to 12 inches of flexible tubing that connects the needle to the collection device

draw blood
Why is the needle syringe system not ideal?
because only a small amount of blood can be obtained with this method

the amout of suction can be controlled by the plunger of the syringe instead of the vacumn method
For a needle syringe system what needle is generally used?
16 gauge injection needle and syringe
Lumen
hollow space inside the needle; also referred to as the guage. The larger guage number, the smaller the diameter
