In medicine, the Birmingham gauge specifies the outside diameter of hypodermic needles, catheters, cannulae and suture wires. It was originally developed in early 19th-century England for use in wire manufacture, and began appearing in a medical setting in the early 20th century. Another common needle gauge system is the French catheter scale.
A peripheral venous catheter is the most commonly used vascular access in medicine. It is given to most emergency department and surgical patients, and before some radiological imaging techniques using radiocontrast, for example. In the United States, in the 1990s, more than 25 million patients had a peripheral venous line each year.
The French scale, French gauge or Charrière system is commonly used to measure the size of a catheter. It is most often abbreviated as Fr, but can often be seen abbreviated as Fg, FR or F. It may also be abbreviated as CH or Ch (for Charrière, its inventor). However, simply gauge, G or GA generally refers to Birmingham gauge.
Ported cannulae have an injection port on the top that is often used to administer medicine.

A Birmingham gauge of 14 is a very large cannula (used in resuscitation settings) and 24-26 is the smallest.

I don't think this statement says enough about what it means to be "recognised" by the US government in order for it to be particularly meaningful. Clearly, Birmingham wire gauge lives on as the Stubs gauge and whether ...
Hypodermic needle features. A hypodermic needle (from Greek ὑπο- (hypo- = under), and δέρμα (derma = skin)), one of a category of medical tools which enter the skin, called sharps, [1] is a very thin, hollow tube with one sharp tip. It is commonly used with a syringe, a hand-operated device with a plunger, to inject substances into the ...
