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.
Claims21
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.
