    Abstract: We describe connectors for safely and conveniently injecting measured doses of sterile liquid medications into a patient via one or more infusion ports in intravenous access assemblies. Each connector comprises a tubular injector divided by a rigid septum which holds a hollow needle sharp on each end safely recessed in a leading and in a trailing chamber. The leading chamber snugly holds the trailing limb and penetrable cap of an inserted standard infusion port. The trailing recess snugly holds the leading end of a cartridge with a leading penetrable diaphragm, a bore containing liquid medication, a cartridge piston and trailing bore suitable for insertion of a separate cartridge plunger having markers for measuring doses delivered; or, alternatively, the pentrable cap and trailing limb of second similar infusion port attached by trailing tubing to a large measured volume infusion source. When assembled such that the trailing cap of infusion port is penetrated by the needle in the leading chamber and the leading diaphragm of the cartridge or, alternatively, the leading penetrable cap on a second infusion port is penetrated by the needle in the trailing chamber, such that flow can proceed through the needle, precisely measured doses of sterile liquid medication can be injected into the venous access assembly without possibilities for the user to touch, get stuck or finger-contaminate the needle or its contents. Unique features added to increase the efficiency of the system are a biased leading end on the tubular injector to conveniently and securely accommodate a Y-infusion port; an eccentric needle in the connector, such that rotation prevents the leading sharp end of the needle from passing through the infusion port cap via the same track; and an easily removed biased cap for keeping the cartridge diaphragm sterile.
