Abstract

Drug delivery devices having integrated non-luer connectors are described. An exemplary drug delivery device includes a container with a non-luer connector that prevents connection of a standard female luer connector to the container. One or more embodiments pertain to a container with a non-luer connector that prevents the formation of a fluid-tight seal between a standard female luer connector and the container. A non-luer connector for attachment to a container having a non-luer element is also described.

First claim

What is claimed is:

1. A non-luer connector for connection to a second non-luer connector, the non-luer connector comprising:
an open distal end, an open proximal end, a proximal wall extending distally from the open proximal end, the proximal wall including an inside surface defining a cavity for receiving at least a portion of the second non-luer connector, and an attachment end extending from the proximal wall, the attachment end including a first narrowed wall extending from the proximal wall to a second narrowed wall disposed distally adjacent to the first narrowed wall, a third narrowed wall disposed distally adjacent to the second narrowed wall and extending to the open proximal end, an inner cross-sectional dimension of the first narrowed wall being less than an inner cross-sectional dimension of the inside surface of the proximal wall, the second narrowed wall having an inner cross-sectional dimension that is less than the inner cross-sectional dimension of the first narrowed wall, the third narrowed wall having an inner cross-sectional dimension that is less than the inner cross-sectional dimensions of the proximal wall, the first narrowed wall and the second narrowed wall; a length of a cavity measured from the open proximal end to an end of the second narrowed wall, but not including the second narrowed wall, being in the range from about 0.200 inches to 0.500 inches, the inside surface of the proximal wall having a taper in the range from 0.5% to 5.9% decreasing in a proximal to distal direction, an outside surface with a radially outwardly extending rim disposed around an entire circumference of the outside surface at the open proximal end of the non-luer connector, the radially outwardly extending rim including a radially outwardly extending tab disposed along at least a portion of the rim, the outside surface including two arms disposed on opposite sides of the non-luer connector that extend from the first narrowed wall to a location adjacent to the open distal end, an annular disc disposed adjacent to the two arms that extends radially outwardly from the outside surface, the third narrowed wall including four protrusions that extend radially outwardly from the outside surface and extend from the annular disc to the open distal end along a same axis.

2. The non-luer connector of claim 1 , wherein the inner cross-sectional dimension of the proximal wall is in the range from about 0.100 inches to about 0.145 inches.

3. The non-luer connector of claim 1 , wherein the inner cross-sectional dimension of the proximal wall is in the range from about 0.1306 inches to about 0.1326 inches.

4. The non-luer connector of claim 1 , wherein the taper decreasing in a proximal to distal direction is in the range from about 3.0% to 5.9%.

5. The non-luer connector of claim 1 , wherein the second non-luer connector comprises a hub body including an open proximal end, an interior surface defining a cavity with an inner cross-sectional dimension measured at the open proximal end of the hub body of less than 0.168 inches and a needle cannula attached to the hub body.

6. The non-luer connector of claim 5 , wherein the inner cross-sectional dimension of the cavity of the hub body at the open proximal end is in the range from about 0.110 inches to about 0.150 inches.

7. The non-luer connector of claim 6 , wherein the inner cross-sectional dimension of the cavity of the hub body measured at the open proximal end is in the range from about 0.1417 inches to about 0.1437 inches.

8. The non-luer connector of claim 5 , wherein the inside surface of the proximal wall has one of a non-circular cross-section, a square cross-section and a triangular cross-section shape and the inner cross-sectional dimension of the inside surface of the proximal wall is selected to form a fluid-tight seal with an elongate tip of a container.

9. The drug delivery device of claim 5 , wherein an inner cross-sectional dimension of the cavity for receiving at least a portion of the second non-luer connector is selected to form a fluid-tight seal with an elongate tip of a container.

10. The non-luer connector of claim 1 , wherein the cavity for receiving at least a portion of the second non-luer connector has a length in the range from about 0.250 inches to about 0.500 inches.

11. The non-luer connector of claim 1 , wherein the taper of the inside surface of the proximal wall is in the range from about 3% to 5.9%.

12. The non-luer connector of claim 1 , wherein the inside surface of the proximal wall has one of a non-circular cross-section, a square cross-section and a triangular cross-section shape.
