4-way Stopcock for Central line blood draws?

I currently work in a busy oncology unit and we have recently had an increase in CLABSIs. We are looking at possible ways to limit the amount of times we are accessing central lines. Right now with a typical blood draw there can easily be 4 or more access events (flush/waste, draw (possibly multiple syringes), flush, flush).

in a previous hispital I worked in we used double stopcocks which allowed a closed flush/waste/draw system and allowed for only one access event for the blood draw. After discussing with my clin spec she is very interested, but I can't seem to find an example of a double stopcock to show her what I'm talking about. Anyone use this type of system and can provide me a manufacturer/part number?

Thank you! I have literally spent hours trying to find these. I don't know why I didn't think to ask here sooner!

You could also throw out the idea for a SafeSet, too. I love them. They come attached to pressure lines, such as CVP/art lines, etc. I wish I could link a picture, but I don't know how to that on my Kindle.

I have seen SafeSets and they look really neat, but we don't have pressure/art lines. I think they would also be cost prohibitive for our purpose.

If you use vacutainers for your bloods you can get a device that attaches to the line, a waste tube then draw your bloods..... flushing pre and post of course.

The main purpose of putting a 4-way in-line (two consecutive 3-way stopcocks) is for having a way of returning the waste in a blood draw without disconnecting the waste syringe. You use it basically the same way you would a VAMP; attach an empty syringe to each of the 2 ports, draw the waste into the upstream syringe, close the line to that syringe, draw your sample in the syringe closer to the patient, then re-open the port to the waste syringe, give that back and then flush. I'm not sure that necessarily cuts down all that much if it all on the number of accesses however.
