Abstract

A needleless connector for adding medication to a parenteral fluid is provided. The connector is provided with a male luer connector at one end and a female connector at the opposite end. A sliding plug valve is built into the connector so that the parental fluid may be isolated from the injection site to prevent back flow when the syringe is removed.

Claims

1. A medical connector comprising;

a housing having a male luer connection at one end and a female luer connection at the opposite end;

a slide receiver intermediate said ends;

a rubber spring bladder disposed within said housing proximate said male luer connector;

a port in said housing immediately above said slide receiver; and

a sliding plug disposed within said receiver having an aperture therethrough alignable with said port.

2. The medical connector of claim 1 wherein said slide receiver is a hollow cylinder and said sliding plug is a solid cylinder having an aperture therethrough alignable with said port.

3. The medical connector of claim 2 further comprising a positioning channel in the inner surface of said slide receiver and a positioning key on the upper surface of said sliding plug.

4. The medical connector of claim 3 further comprising an aperture O ring disposed about said aperture adjacent said port.

5. The medical connector of claim 3 further comprising two plug O rings, one each of said plug O rings disposed about said sliding plug between the aperture and each end.

6. A medical connector comprising;

a housing having a male luer connection at one end and a female luer connection at the opposite end;

a hollow cylindrical slide receiver intermediate said ends;

a rubber spring bladder disposed within said housing proximate said male luer connector;

a port in said housing immediately above said slide receiver;

a cylindrical sliding plug disposed within said receiver having an aperture therethrough alignable with said port;
