A retractable multi-piece cover for use in removal of a needle delivery system over a central venous access port which is subcutaneously implanted into a patient. The multipiece cover extends to surround the intravenous therapy needle during its removal from the port so that the person removing the needle is protected from the possibilities of spattering blood and needle stick resulting from needle rebound. The multi-piece cover may have an upper slit in its extendable upper portion, or a larger opening in its extendable upper portion covered with flexible material through which an intravenous therapy needle may access the port. The multi-piece cover may also have a clamp for securely attaching the multi-piece cover to the intravenous therapy needle. Applications may include, but are not limited to, use over subcutaneously arm-implanted ports and subcutaneously chest-implanted ports.
