An injection needle, also known as a hypodermic needle, is a thin, hollow tube with a sharp tip used to deliver medication or fluids into the body.
Hypodermic needles are a common medical tool used by healthcare professionals like dentists, phlebotomists, physicians, pharmacists, nurses, and paramedics. However, some patients, such as those with type 1 diabetes who require multiple insulin injections daily, may administer injections themselves.
Hypodermic needles come in various sizes and gauges, depending on the intended use and the amount of medication being administered. Different needle gauges are used for different purposes, such as intramuscular injections, subcutaneous injections, and intravenous injections.
