An apparatus is disclosed for intravenous administration of fluid to which fluid may be added according to the process also disclosed, by injecting same, using a syringe, but not a needle, directly into the hollow portion of the apparatus through an opening therein. A normally closed backflow check valve device, having a component thereof acting as a means for receiving the fluid by engagement to the syringe, has been permanently sealed into the opening in the hollow portion of the apparatus. The apparatus is capped by a double luer locking cap, the purpose of which is to protect the opening into the apparatus from contamination. This is accomplished by using a cap structure wherein the cap which will ultimately re-cover the opening is locked into and protected by the cap which initially covers the opening and then discarding this initial cap after the apparatus has been filled.
