Syringe and Needle Components

  • Lumen: The hollow internal section of the needle allowing fluid passage.
  • Bevel: The slanted tip of the needle which facilitates smooth entry into tissues.
  • Barrel: The body of the syringe that holds the medication in place.
  • Hub: The connection point where the needle attaches to the syringe, ensuring a secure fit.
  • Thumb Plunger: The mechanism that is pressed to inject medication through the syringe.
  • Flange: An attachment designed for the index and middle fingers, providing stability while injecting.
  • Gauge: A measurement indicating the size of the needle; smaller numbers represent larger diameters.
  • Bottom of Rubber Stopper: The point used to measure medication accurately within the barrel gauge.
  • Break the Seal: A process to prepare the syringe for use by pulling the plunger back and forth to loosen any seals.
  • Safety Device: A feature incorporated into needles that activates post-injection to prevent needle stick injuries.
  • Sheath: A protective covering that guards the needle before use.
  • Shaft: The outer portion of the needle that connects the bevel to the hub, affecting the length and penetration depth.
