ABSTRACT:
A fluid injection device for an intravenous delivery system that has an access port for insertion of liquid medication. The access port is sealed with a resilient, compressible closure element adapted to be forced into the port into a sealing condition. The closure element has a preformed central passage formed therein and is adapted to have a normal uncompressed condition and a sealing condition wherein the element is pressed into the access port to compress it sufficiently to close the passage. An elongated, hollow injection probe is used to penetrate the closure element through the preformed passage. The injection probe has a relatively blunt forward end so that when the probe penetrates the seal element, fluid to be administered may be delivered to the sterile interior through the probe.
