Abstract: A flow restriction device may include a male luer connector portion and a female luer connector portion. The male luer connector portion can define a first lumen and the female luer connector portion can define a second lumen. A flexible tubing preferably provides fluid communication between the first lumen and second lumen. The flexible tubing can be helically wound around a solid core, and the flexible tubing can be helically wound within a hollow chamber. The flexible tubing is configured to increase flow resistance through the tubing to reduce shear stress on the fluid, thereby decreasing the incidence of hemolysis.
