  1. Spike/Piercing Pin
    • This is directly above the drip chamber and is the end that goes into the container.  It needs to remain sterile.  Remove the protective covering from the IV bag/bottle before you remove the protective covering from the spike.  Keep your hands below the
    • shield/flange when you are piercing a new bottle
  2. Drip Chamber
    • Should be 1/3 to ½ full.  If it is too full,
    • clamp off tubing and invert and squeeze to return fluid to container.  If there is a little needle apparent in the drip chamber it is a mini drop (60 gtt/ml).
  3. Back-check valve
    • Permits intermittent infusion of a secondary solution and, on its completion, automatically returns to infusion of the primary solution.  The back check valve will close from pressure, stopping the primary solution from infusing allowing for one-way flow of solution.
  4. Roller clamp or up and down slide
    • Used to regulate flow.  As soon as you take
    • the tubing out of the box, move the clamp up and clamp off.  Be sure clamp is off before you fill drip chamber.  Otherwise, you get lots of bubbles in you tubing and have to waste fluid to prime tubing.
  5. Side ways (Horizontal) slide clamp
    Used only as on or off…not to regulate flow
  6. Luer slip
    • – At the end of the tubing.  Has a protective
    • covering and must remain sterile. Usually you can prime the tubing with the covering on, if protective covering is removed, maintain aseptic technique.(most now have luer
    • lock)
  7. Y-site
    • Allow for you to piggyback IV solutions or to administer IV Pushes.  Generally you use the Y-site closest to the insertion site for IV pushes, and more proximal ones for IVPBs.  When priming IV tubing, it is necessary to
    • prime Y-sites.  This is done by inverting
    • (pointing toward floor) the Y-site.
  8. Vented versus non-vented tubing
    • Vented tubing must be used in all
    • non-vented IV bottles to allow air to enter the bottle and displace the solution as it flows. Non-vented tubing should be used with bottles having a built-in vent and with IV bags
  9. Filter
    Allows the fluid, but not particular matter, to pass.
