Blood Collection Device and Related Systems and Methods

Abstract:

A blood collection device to reduce hemolysis in a peripheral intravenous catheter system may include a distal end. The distal end of the blood collection device may include a male luer adapter, which may include a distal opening. The blood collection device may include a cannula in fluid communication with the male luer adapter. The cannula may include a distal end and a sharp proximal tip. The blood collection device may include an elongated neck disposed between the male luer adapter and the sharp proximal tip. The blood collection device may include a fluid pathway extending from the distal opening through the sharp proximal tip. A diameter of the fluid pathway may be constant. An entire length of the fluid pathway is represented by L, and the diameter of the fluid pathway is represented by D. D.sup.4/L may be equal to or less than a predetermined value.
