A syringe refers to a special medical needle device that is used for injecting medicine. This device penetrates the skin with a needle before the medicine is released from a cylinder area. A sterile syringe refers to a needle that has been protected from bacteria through formal cleaning processes called sterilization. These needles are typically wrapped in special sealed plastic after sterilization to ensure minimal bacteria infiltration.

Syringes come in many shapes and sizes. They are purchased based on the volume of medicine that is required to be injected. Each syringe includes a needle, injection plunger control, and medicine cylinder tube area.
