A hypodermic needle syringe is a sterile medical device designed for the injection of liquids (such as medications or vaccines) directly into the body or for the withdrawal of fluids such as blood. It consists of a clear cylindrical barrel, a plunger for drawing up and expelling fluids, and an attached or detachable hypodermic needle. These syringes are widely used in hospitals, clinics, laboratories, and home healthcare for precise and safe delivery of medications.
