A syringe is a medical device used to inject fluids into or withdraw fluids from the body. This specific syringe is designed for single use, ensuring hygiene and safety for patients and healthcare providers. It features a clear, graduated barrel that allows for accurate measurement of liquids, with markings in milliliters (mL) up to 20 mL. The barrel is made of transparent plastic, enabling visibility of the contents. The plunger is smooth for easy operation, providing a comfortable grip while administering injections. A protective cap covers the needle or dispensing tip to maintain sterility when not in use.
