Drawing needles, also known as draw up needles, are often used to extract medication out of vials, bottles, or glass ampules. Another common use is to draw blood. Doctors use them at clinics to pull from samples for testing purpose, and blood drive workers use them to obtain the fluid from donors.
In fact, the purpose of a drawing needle depends largely on its gauge. For example, smaller gauges like 16 and 17 can collect more fluids in a shorter time. This makes them ideal for blood donations (though the larger needles may seem less than ideal to the donors themselves). On the other end of the spectrum, not as much blood is required from patients when doctors want to run tests. Larger gauges like 20, 21, and 22 are perfectly fine for venipuncture. Finally, when it comes to medication vials, the most commonly used needles are the more balanced 18 gauge needles.
