Abstract
Abstract Disclosed is a connector system for medical applications such as intravenously introducing medication 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 medication 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.

Claims Analysis
Total Claims: 16
Claim 1
Independent Claim
143 words
A connector system for intravenously introducing medication into a patient, comprising: a cap member having a cavity therein in which is lodged a needle in a manner whereby the needle is recessed within the cavity, a branch connector having a first inlet port adapted to be connected by tubing means to a source of parenteral liquid, an outlet port through which the parenteral liquid flows via tube means into the patient, and a second inlet port having seal means which is adapted to be penetrated by the needle, said medication flowing from a source through the needle into the parenteral liquid flowing through the connector, and means coupling the second inlet port and the cap member securely together, with the needle penetrating the seal means, whereby movement of the patient does not result in the removal of the needle from the seal means.
Claim 2
Dependent Claim
143 words
A connector system for intravenously introducing medication into a patient, comprising: a cap member having a cavity therein in which is lodged a needle in a manner whereby the needle is recessed within the cavity, a branch connector having a first inlet port adapted to be connected by tubing means to a source of parenteral liquid, an outlet port through which the parenteral liquid flows via tube means into the patient, and a second inlet port having seal means which is adapted to be penetrated by the needle, said medication flowing from a source through the needle into the parenteral liquid flowing through the connector, and means coupling the second inlet port and the cap member securely together, with the needle penetrating the seal means, whereby movement of the patient does not result in the removal of the needle from the seal means.
Claim 3
Dependent Claim
48 words
2 . The connector system of Claim 1 wherein the internal walls of the cap member guide the needle so that said needle penetrates the central portion of seal means as the cap member is fitted over the second inlet port and does not scrape against the connector.
Claim 4
Dependent Claim
33 words
The connector system of Claim 2 wherein the cavity provides a chamber which surrounds .the needle, with said needle being lodged within the chamber so that it is not likely to be contaminated.
Claim 5
Dependent Claim
32 words
The connector system of Claim 3 wherein the cap member is screwed onto the second inlet port, said cap member having internal threads which engage external threads adjacent the second inlet port.
Claim 6
Dependent Claim
28 words
The connector system of Claim 4 wherein the cap member has outwardly extending wings that permit the cap means to be easily screwed onto the second inlet port.
Claim 7
Dependent Claim
111 words
6 . A connector system for introducing medication into a patient, comprising: feeding means through which liquid flows into the patient, said feeding means having a port therein including seal means which close said port, said seal means being adapted to be penetrated by a needle, and a cap member secured to the port, said cap member having a cavity therein which forms a chamber in which is lodged a needle which does not project beyond an open end of the cavity, said needle penetrating the seal means when the cap member is covering the port, with said medication being fed through the needle into the liquid flowing into the patient.
Claim 8
Dependent Claim
111 words
6 . A connector system for introducing medication into a patient, comprising: feeding means through which liquid flows into the patient, said feeding means having a port therein including seal means which close said port, said seal means being adapted to be penetrated by a needle, and a cap member secured to the port, said cap member having a cavity therein which forms a chamber in which is lodged a needle which does not project beyond an open end of the cavity, said needle penetrating the seal means when the cap member is covering the port, with said medication being fed through the needle into the liquid flowing into the patient.
Claim 9
Dependent Claim
125 words
A connector system used in the treatment of a patient, comprising: feeding means having a tubular conduit member serving as a male component and having an open end sealed by seal means which close off the open end, said seal means being adapted to be penetrated by a needle, and a cap member removably secured to the conduit, said cap member serving as a female component and having a cavity therein in which is centrally lodged a needle, said cavity having internal side walls which fit snugly around the tubular conduit member and guide the needle into the central portion of the seal means when the cap member and conduit interact in a male-female mating relationship when the cap is placed on the conduit member.
