👉 A hypodermic is a device used for injecting medication, usually through a syringe into the skin or mucous membrane of the body. They are often used in the treatment of wounds and infections where it's difficult to insert an intramuscular needle. In medical terms, they refer to a type of injection device that delivers medications directly into the skin or mucous membranes without requiring a needle, making them particularly useful for treating conditions such as wounds, burns, and infections.
