- Push button safety mechanism
- Translucent Body allowing Flash Visibility
- 1/2-3/4 inch needle permanently connected to a 5-12 inch length of tubing
- syringe attached to hub
- hub to luer multisampler to tube holder
Why do we use a sharps disposal and not the garbage?
So no accidental pokes happen when taking out the garbage
What are the guidelines for Venipuncture vs Skin puncture?
Venipuncture may be contraindicated for:
* Patients with burns or scars over venipuncture sites
* For those at risk of serious complications venous thrombosis or iatrogenic anemia
* Patients with bleeding issues
What do you need to be aware of when doing a capillary collection?
Observed
- Micro collection tubes should be slanted downward
- Avoid scrapping the finger or heel with the collection container
- Tap container lightly to move blood to bottom
- Be careful to always achieve the minimum volume and to not exceed the maximum.
How to deal with complications
1 - failure to draw blood?
2 - rolling veins?
3 - sclerosed(occluded) veins?
4 - collapsed veins?
5 - hematoma or a thrombosed area?
6 - burned area or scared site
- Rotate Needle - bevel stuck in wall
Slowly pull back - needle passed through vein
Slowly advance - needle not advanced far enough
vacuum pulled vein into bevel - tube too big for vein - Anchor firmer
- result of chemo, repeated venipunctures, inflammatory disease - susceptible to infection
- Pick a different site - blood flow is blocked. ??
- Do not draw blood from - blood flow into vein restricted, erroneous results
- Hard to penetrate, painful, susceptible to infection
What tests need to be kept on ice after venipuncture?

What tests need to be kept warm after venipuncture?
Cold agglutinin
Cryoglobulin
How long do SST tubes need to sit before centrifuge?
