Abstract
A hollow spike has a pointed distal end, a proximal end, and a luer fitting positioned in the proximal end of the spike to engage a complementary fitting associated with another IV component, e.g., an IV line. A reflex valve is disposed in the luer fitting to permit fluid flow through the spike when a complementary fitting is connected to the luer fitting of the spike, and to prevent fluid flow through the spike when no fitting is engaged with the fitting of the spike.
