ABSTRACT:
A needleless connector for adding medication to a parenteral fluid is provided. The needleless connector comprises a connector adapted to receive a syringe and having a check valve to seal the port in place of a puncture pad. The check valve comprises a resilient disc held in place and biased closed by the tensile stress of the check valve material. When a syringe or other apparatus having a male luer connector is engaged with the connector and fluid pressure is applied to the check valve the resilient disc is deformed which allows the medication to flow through the connector into the tubing and thus to the patient.
