Injection Devices

Syringes & Needles are sterile, single-use medical devices used for parenteral administration of medications, withdrawal of bodily fluids, and blood collection. A syringe consists of a graduated barrel and plunger; a needle consists of a hub and hollow beveled cannula. Available in a wide range of volumes (0.5 mL to 60 mL), needle gauges (18G to 30G), and lengths (3/8" to 3.5"), selection is determined by route of administration, medication volume, and patient characteristics. Safety-engineered devices with passive or active needle shielding are standard to prevent sharp injuries. Strict aseptic technique, immediate disposal into puncture-resistant sharps containers, and absolute single-use protocols are critical for patient safety and healthcare worker protection.
