Abstract
A needleless injection port and automatic backcheck valve comprises a generally tubular body having a pair of vertically offset ports extending laterally therefrom, and a spool within the bore for controlling communication between the ports. The spool is urged by a spring toward one end of the bore, which is open so that a syringe tip can be inserted to displace the spool from a position in which the ports communicate to a position in which they are isolated and secondary medication can be injected from the syringe.
