A hypodermic needle is a medical tool used for injecting substances into the body or drawing fluids from it. Here are some key points:

1. Structure: A hypodermic needle consists of a hollow needle attached to a syringe. The needle has a sharp, beveled tip to easily penetrate the skin and tissues.
2. Uses: Commonly used for administering medications, vaccinations, and drawing blood samples. It can also be used for intravenous (IV) therapy and other medical procedures.
3. Sizes: Hypodermic needles come in various sizes (gauges) and lengths, depending on the specific medical need. The gauge refers to the diameter of the needle, with a higher gauge number indicating a thinner needle.
4. Sterility: These needles are typically sterile and single-use to prevent infections and ensure patient safety.
5. History: The invention of the hypodermic needle in the mid-19th century revolutionized medical practice, allowing for more effective and precise administration of treatments.

Proper usage and disposal of hypodermic needles are crucial for preventing injuries and infections.
