Systems and methods for phlebotomy through peripheral IV catheter

Abstract

An apparatus for performing phlebotomy through a peripheral intravenous line is described herein. The apparatus includes an introducer and a cannula and is configured to advance the cannula through a peripheral intravenous line. A y-adapter with a port of larger diameter is configured to receive the cannula to place the cannula in fluid communication with the peripheral intravenous line. When advanced, the cannula is configured to transport a bodily fluid to a volume outside of the body.

Problems solved by technology

A third apparent obstacle is attributed to the "suction cup" effect, in which the negative pressure created by suction through the catheter and possibly tortuous venous access causes the tip of the catheter to adhere to the wall of the vein

When the negative pressure increases, the veins can be damaged causing a "blown open vein" which is a major problem for phlebotomists when inhaling through PIV
