#2 HYPODERMIC NEEDLE
Ancient Greeks and Romans used thin, hollow tools to introduce fluids into the body, a precursor to the modern needle. In 1656, Christopher Wren used a goose quill as a crude needle to deliver intravenous injections into dogs.
The hypodermic needle as we know it was invented in the mid-1800s by Charles Pravaz and Alexander Wood. Hypodermic refers to anything just below the surface of the skin.
Today, the hypodermic needle is used together with a syringe to inject or extract fluids, medication and blood from our bodies with minimal pain and reduced risk of contamination.
