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.
