Abstract

A stopcock including a stopcock body including a central axial opening, and first and second stopcock luer connectors extending radially and in fluid communication with the central axial opening. The stopcock includes a stopcock core axially disposed within the central axial opening. The stopcock core includes an engagement end axially connectable with a syringe, an axial port formed at the engagement end for fluidly communicating with the syringe, a first radial port, and a first passage extending between the axial port and the first radial port. The stopcock core has a first position with the first radial port in fluid communication with the first stopcock luer connector. The stopcock core has a second position with the first radial port in fluid communication with the second stopcock luer connector. The core is rotatable from the first position to the second position upon the syringe being axially rotated.
