A unique external injection port cover is provided that is open at one end, closed at the other end, and includes a set of spiraling screw threads on the inside. It is designed to be screwed into place over a specially adapted external injection port having its own corresponding screw threads. The inside of the closed end of the cover includes an inwardly pointing projection. A sponge is provided inside the open end, and a shatterable plastic capsule containing a combination of antiseptic, bactericidal and virucidal agents is provided between the sponge and the projection. A flexible O-ring seal is provided on the inside of the cover near the open end. When the present invention is screwed into place over an injection port, the O-ring first creates a seal over the end of the port. As the invention is tightened down, the pressure between the projection and the breakable capsule causes the capsule to rupture thereby releasing the antiseptic agents inside to be soaked up by the sponge. When completely tightened, the antiseptically treated sponge comes into contact with the latex membrane of the port, keeping it saturated, clean and aseptic until the cover is removed. The present injection port cover requires no maintenance when not in use resulting in decreased risk of infection and longer life of the injection port itself.
