The first true hypodermic syringe was created by Alexander Wood in 1853. He modified a regular syringe, which at that time was used for treating birthmarks, by adding a needle. He then used this new device for introducing morphine into the skin of patients who suffered from sleeping disorders.
A hypodermic needle is used for rapid delivery of liquids, or when the injected substance cannot be ingested, either because it would not be absorbed (as with insulin), or because it would harm the liver.There are many possible routes for an injection.r. Charles Hunter, a London surgeon, is credited with the coining of the term hypodermic to describe subcutaneous injection in 1858. The name originates from two Greek words: hypo, under, and derma, skin.
