Abstract

A device for coupling to a fluid connector of an IV administration set to resist contamination of the fluid connector and IV administration set and permit priming of the IV administration set. The device including a cover body having a cavity for receiving the fluid connector, a priming passage for priming fluid from the IV administration set through the fluid connector, and a coupling tab extending from the cover body, the coupling tab permitting the cover body to be coupled to a length of an IV line or other portion of the IV administration set to resist contamination and permit priming of the IV administration set.

First claim

What is claimed is:

1. An intravenous (IV) priming cap comprising:
a cover body having a proximal end, a distal end, and an inner surface defining a connector cavity extending into the cover body from the proximal end toward the distal end, the connector cavity comprising a first end at the proximal end of the cover body and a second end proximal to the distal end of the cover body and defining a distalmost end of the connector cavity, wherein a cross-sectional width of the connector cavity tapers from the first end of the connector cavity to the second end of the connector cavity, and wherein the connector cavity comprises a longitudinal connector cavity axis extending from the proximal end toward the distal end of the cover body;
a priming passage that extends from the second end of the connector cavity to outside the cover body, the priming passage comprising a volume that is less than a volume of the connector cavity; and
a coupling tab extending from an outer surface of the cover body, the coupling tab comprising a base portion coupled to the cover body, a middle portion extending from the base portion, and a tip portion, wherein the tip portion extends from the middle portion toward the cover body, and wherein the coupling tab comprises a height extending from a proximal surface of the coupling tab to a distal surface of the coupling tab, and in a first direction from the proximal end toward the distal end of the cover body, wherein the proximal surface of the coupling tab extends from the base portion to the tip portion, wherein the proximal end of the cover body and the proximal surface of the coupling tab are coplanar, and the distal surface along the middle portion of the coupling tab extends in a direction toward the proximal surface such that the height of the coupling tab decreases from the base portion toward the tip portion of the coupling tab, and
a tubing passage through the coupling tab, and a slot extending through an outer surface of the coupling tab to the tubing passage, wherein the tubing passage extends entirely through the coupling tab in the first direction to define a longitudinal tubing passage axis such that the coupling tab is configured to engage against a length of tubing moved through the slot to the tubing passage.

2. The IV priming cap of claim 1 , wherein the coupling tab comprises a first coupling arm and a second coupling arm, each of the first coupling arm and the second coupling arm extending between the base portion and the tip portion of the coupling tab.

3. The IV priming cap of claim 2 , wherein each of the first coupling arm and the second coupling arm comprise an inner surface facing the other of the first coupling arm and the second coupling arm, and wherein the tubing passage and the slot are defined between the inner surface of the first coupling arm and the second coupling arm.

4. The IV priming cap of claim 1 , wherein the slot extends in a direction from the tip portion of the coupling tab toward the base portion.

5. The IV priming cap of claim 1 , wherein the coupling tab comprises an inner surface, and wherein the tubing passage and the slot are formed between the inner surface of the coupling tab and the outer surface of the cover body.

6. The IV priming cap of claim 5 , wherein the coupling tab extends along the outer surface of the cover body in a second direction that is transverse to the longitudinal connector cavity axis.

7. The IV priming cap of claim 1 , wherein the base portion extends from the cover body in a second direction that is transverse to the longitudinal connector cavity axis, and the tip portion extends from the base portion in a third direction that is different than the second direction.

8. The IV priming cap of claim 7 , wherein the third direction is transverse to the longitudinal connector cavity axis.

9. The IV priming cap of claim 1 , wherein the cover body comprises any of a rib and channel extending along the outer surface of the cover body.

10. The IV priming cap of claim 1 , wherein the priming passage extends through any of the proximal end and the distal end of the cover body.

11. The IV priming cap of claim 1 , comprising a hydrophobic filter positioned along the priming passage.

12. The IV priming cap of claim 1 , wherein the coupling tab comprises a length, defined from the base portion to the tip portion, that is approximately equal to a cross-sectional length defined by the outer surface of the cover body at the proximal end thereof.

13. An intravenous (IV) priming cap comprising: a cover body having a proximal end, a distal end, and an inner surface defining a connector cavity extending into the cover body, the connector cavity comprising a cross-sectional width that tapers from a first end of the connector cavity at the proximal end of the cover body to a second end of the connector cavity adjacent to the distal end of the cover body and defining a distalmost end of the connector cavity, and wherein the connector cavity comprises a longitudinal connector cavity axis between the proximal end and the distal end, and a priming passage extends from within the connector cavity to outside the cover body, the priming passage comprising a volume that is less than a volume of the connector cavity; and
a coupling tab extending from an outer surface of the cover body, the coupling tab comprising a base portion coupled to the cover body, a middle portion extending from the base portion, and a tip portion, a tubing passage, and a slot defined between an inner surface of the coupling tab and the outer surface of the cover body, wherein the tip portion extends from the middle portion toward the cover body, the coupling tab comprises a height extending in a first direction from a proximal surface of the coupling tab to a distal surface of the coupling tab, wherein the proximal surface of the coupling tab extends from the base portion to the tip portion, wherein the proximal end of the cover body and the proximal surface of the coupling tab are coplanar, and the distal surface along the middle portion of the coupling tab extends in a direction toward the proximal surface such that the height of the coupling tab decreases from the base portion toward the tip portion of the coupling tab, and wherein the tubing passage and the slot extend entirely through the coupling tab, in the first direction.

14. The IV priming cap of claim 13 , wherein the slot extends laterally, relative to the longitudinal connector cavity axis.

15. The IV priming cap of claim 13 , wherein the base portion extends from the cover body in a second direction that is transverse to the longitudinal connector cavity axis, and the tip portion extends from the base portion in a third direction that is different than the second direction.

16. The IV priming cap of claim 15 , wherein the third direction is transverse to the longitudinal connector cavity axis.

17. The IV priming cap of claim 13 , wherein the cover body comprises any of a rib and channel extending along the outer surface of the cover body.

18. The IV priming cap of claim 13 , wherein the priming passage extends through any of the proximal end and the distal end of the cover body.

19. The IV priming cap of claim 13 , comprising a hydrophobic filter positioned along the priming passage.

20. The IV priming cap of claim 13 , wherein the coupling tab comprises a width extending in a second direction, where the second direction is transverse relative to the first direction, and wherein the width of the coupling tab decreases from the ba
