US Patent 7611502 Connector for enteral fluid delivery set

A connector for use in connecting a container of liquid nutrients to an enteral feeding tube to supply the liquid nutrients to a patient includes an integrally formed spike projecting into a cavity defined by an interior surface of a body of the connector. An air passage in communication with the cavity extends through the spike to outside the connector. A filter is secured to the end of the passage outside the connector. The body of the connector is free of structure that both defines any portion of the liquid passage and is formed for penetrating the puncturable seal of the container.
