Abstract
A flow restriction device may include a male luer connector portion, a female luer connector portion, a tube, and an overmolded body portion. The male luer connector portion defies a first lumen. The female luer connector portion defines a second lumen. The tube defines a third lumen. The third lumen is in fluid communication with the first lumen and the second lumen. The third lumen has a diameter less than 0.025 inches. The overmolded body portion is formed around the tube.
