Hypodermic needle
A hypodermic needle (from Greek ὑπο-, and δέρμα) is a hollow needle commonly used with a syringe to inject substances into the body or extract fluids from it. They may also be used to take liquid samples from the body, for example taking blood from a vein in venipuncture. Large bore hypodermic intervention is especially useful in catastrophic blood loss or shock.
