Abstract

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 outsid e 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 liqu id passage and is formed for penetrating the puncturable seal of the container.

Claims (16)

1. A connector for use in connecting a container of liquid nutrients to an enteral feeding tube to supply the liquid nutrients to a patient, the connector comprising:
a body having an interior surface defining a cavity for receiving an outlet of the container, and an exterior surface;
a liquid passage defined in the body having a first end in fluid communication with the cavity and a second end for connection to the enteral feeding tube to fluidly connect the container and the enteral feeding tube when the connector is received on the container;
a spike formed integrally with the body and having a free end projecting into the cavity for piercing a puncturable seal covering the outlet of the container as the outlet of the container is being received in the cavity;
an air passage extending through the spike to the exterior surface of the body for introducing air from outside the connector into the container when the connector is attached to the container; and the body being free of structure that both defines any portion of the liquid passage and is formed for penetrating the puncturable seal of the container.
2. A connector as set forth in claim 1 wherein no portion of the liquid passage extends into the cavity.
3. A connector as set forth in claim 2 wherein the interior surface of the body includes an upper surface section, the liquid passage having an opening generally flush with the upper surface section.
4. A connector as set forth in claim 3 wherein the spike projects from the interior surface of the body.
5. A connector as set forth in claim 4 wherein the spike is spaced from the liquid passage opening on the interior surface.
6. A connector as set forth in claim 3 wherein the upper surface section is substantially flat.
7. A connector as set forth in claim 1 further comprising an air filter and a filter mount disposed on the exterior surface of the body in fluid communication with the air passage for connecting the air filter to the body.
8. A connector as set forth in claim 1 wherein the body has a cylindrical lower portion and a cylindrical upper portion projecting from the lower portion, the interior surface at the lower portion having internally projecting threads for threadably attaching to a container with a threaded, larger diameter outlet, the interior surface at the upper portion being adapted for snap fitting to a container with a smaller diameter outlet.
9. A connector as set forth in claim 8 wherein the liquid passage is partially defined by a tubular conduit projecting outward from the exterior surface of the upper portion of the body and having threads on its exterior surface for threadable attachment to the enteral feeding tube.
10. A connector as set forth in claim 1 wherein the spike has a generally flat bottom surface and the air passage opens at the flat bottom surface into the cavity.
11. A connector as set forth in claim 10 wherein the spike has a knife edge extending along its length.
12. A connector as set forth in claim 11 wherein the bottom surface of the spike lies generally in a plane intersecting a central axis of the body at an angle thereby to form a tip at a lower end of the knife edge.
13. A connector as set forth in claim 1 wherein the body has a central axis, the spike being spaced from the central axis.
14. A connector as set forth in claim 13 wherein the liquid passage has an opening in its first end having a longitudinal axis spaced from the central axis of the body.
15. A connector as set forth in claim 1 wherein the spike has first and second opposite broad sides, and first and second opposite narrow sides, the second narrow side being beveled from the second broad side to the first broad side, so that a cutting edge is formed where the second narrow side meets the first broad side, the second narrow side tapering toward the free end of the spike such that a folding edge is formed where the second narrow side meets the second broad side.
16. A connector as set forth in claim 15 wherein the first broad side is generally arcuate.
