FAQ: How To Draw Blood With A Butterfly?

Using Butterfly Needles for Blood Draws and IVs

A butterfly needle is a device that consists of a hypodermic needle, two flexible “wings,” a flexible transparent tubing, and a connector that is used to draw blood from a vein or deliver intravenous (IV) therapy. Butterfly needles have some advantages over straight needles.
Butterfly needles are used by phlebotomists to obtain blood samples for various tests and can be left in a vein for up to seven days if properly secured. Butterfly needles are measured in gauges and typically range in size from 18-gauge to 27-gauge.

How do you insert a butterfly needle?
