-18- MEDICAL CONNECTOR SYSTEM ABSTRACT OF THE DISCLOSURE Disclosed is a connector system for medical applications such as intravenously introducing medica- tion into a patient. In intravenous applications a feeding system is employed through which parenteral liquid flows into the patient intravenously via a needle attached at one end to the feeding system and having its pointed end inserted into the patient's vein. The feeding system includes a port at the end of a conduit which has a seal associated with it which closes said port but is adapted to be penetrated by a second needle. This second needle is connected to a source of medica- tion which flows through the second needle and mixes with the parenteral liquid flowing into the patient. A cap member is secured to the port and it carries within a cavity the second needle which penetrates the seal when the cap member is covering the port. Because the cap is secured to the port, movement of the patient will not result in the second needle being pulled from the seal. The needle is lodged deep within the cavity so that if the cap is placed, for example, on the patient's bed, the needle will not directly contact bacteria which may be on the bed. To avoid scraping material from the internal conduit walls with the needle, a potentially lethal event, the cap member serves as a guide which directs the needle into the center of the seal, well away from the internal conduit walls.
