Butterfly needle. A winged infusion set—also known as "butterfly" or "scalp vein" set—is a device specialized for venipuncture: i.e. for accessing a superficial vein or artery for either intravenous injection or phlebotomy.
The most commonly used are as follows: a 21g (green top) needle, a 22g (black top) needle, a 21g (green label) butterfly needle, a 23g (light blue label) butterfly needle, and a 25g (orange or dark blue label) butterfly needle (however this needle is only used in pediatrics or extreme cases as it is so small that it can often result in ...
The Birmingham gauge ranges from 5/0 or 00000, the lowest gauge number corresponding to the largest size of 0.500 inches (12.7 mm), to 36, the highest gauge number corresponding to the smallest size of 0.004 inches (0.10 mm). The increments between gauge sizes are not linear and vary. [2]
Changing needle size is the best way to control one's own gauge for a given pattern and yarn. Finally, the knitter's tension, or how tightly one knits, can affect the gauge significantly. The gauge can even vary within a single garment , typically with beginning knitters; as knitters become more familiar with a stitch pattern, they become more ...

A needle gauge makes it possible to determine the size of a knitting needle. Some may also be used to gauge the size of crochet hooks. Most needles come with the size written on them, but with use and time, the label often wears off, and many needles (like double-pointed needles) tend not to be labelled.
Comparing this with recommended needle sizes, yarn, and the knitter's own signature tension, allows for adjustments to all of these things. For example, changing needle size is one way to bring the test swatch nearer to an accurate measurement in yarn weight. [4] The gauge swatch goes further.
