This is a completely closed system no blood leaks out and yes you can even use on an established lock just flush site with 1 2 cc nss draw off a 5 cc waste and continue to draw into blood tubes.

Using the existing piv line as a conduit to the vein a flexible internal flow tube is advanced through the piv beyond the catheter tip and into the vessel to collect a blood sample. This flow tube is designed to extend beyond the suboptimal draw conditions around the iv to reach vessel locations where blood flow is optimal for aspiration. Using a similar design the investigators compared chemical and hematological parameters in individuals with a peripheral iv running by either using a tourniquet between the iv site and draw site and drawing below the iv or drawing from the other arm.

But as simple as it sounds there are several factors to consider. Grab the patients lower arm below site of puncture firmly to draw the skin taut and anchor the vein from rolling. Drawing from the iv site after a two minute pause in iv fluids also seemed to work fairly well.

Most of the sharpshooters have gained their skill through continuous practice. If this does not happen then the needle has either not punctured the vein or the needle went through the vessel. Yes a nurse can draw blood from an existing peripheral iv and at the time of insertion.
