Parts of a syringe • Barrel (non-sterile) • Flange on the Barrel (non-sterile) • Plunger (rubber portion and the shaft are sterile) • Flange on the Plunger (non-sterile) • Syringe Tip (Needle Attachment – sterile) • Calibrated Scales – markings vary from 0.01 on 1 ml syringe to 0.2 ml on 3-5 ml syringe; insulin syringes measure in units (1 or 2 units) always check the calibrated scale

7. Major types of needles • Gauges (diameter) • 14-28 gauge • Length (how long the needle is) • ¼ inch – 3 inch

11. Keep it sterile 1. The Needle must never touch anything which isn't sterile.2. The barrel tip of the syringe should also not touch anything except the needle's hub end. (this could contaminate the entire interior of the barrel)3. The rubber plunger should not be touched.4. The area of the plunger that extends into the barrel should also be avoided.So, that leaves just the outer barrel, the finger flange, and the thumb tip of the plunger.
