What is syringe?

A syringe is a medical instrument used to inject fluids into, or withdraw fluids from, the body. It consists of a needle attached to a hollow cylinder (barrel) that is fitted with a sliding plunger.

  • Parts of a Syringe: The main parts include the barrel (marked with measurements), the plunger (for pushing or pulling fluid), and the needle (for piercing skin).

  • Types of Syringes: Syringes come in various sizes and types, including standard syringes, insulin syringes, tuberculin syringes, and prefilled syringes.

  • Uses of Syringes: Common uses include administering medications (vaccines, antibiotics, etc.), withdrawing blood for testing, and injecting contrast dyes for imaging.

  • Syringe Safety: Safe handling and disposal of syringes are crucial to prevent the spread of infections like HIV and hepatitis. Needle stick injuries are a significant concern.

  • Syringe Materials: Syringes are typically made of plastic or glass. Needles are made of stainless steel.

  • Sterilization: Syringes must be sterile before use to prevent infection. Single-use, disposable syringes are the standard in modern healthcare.
