摘要： A self-priming IV set valve includes a connector including a valve element that is positioned inside of the connector, and a cap that is removably connected to the connector. When the cap is mounted to the connector a passageway is formed in the connector such that air and liquid are permitted to pass through the connector and into the cap whereupon a hydrophobic filter of the cap prevents the passage of liquid there through while the hydrophobic filter permits the passage of air out of the cap and into the atmosphere. When the cap is not mounted to the connector, the valve element of the connector is configured to open under pressure and close when pressure ceases. Also disclosed is a method of priming the IV set, a cap assembly for a self-priming IV set valve, and a connector for a self-priming IV set valve.

摘要： A valve includes a one-piece plastic body, and a plunger assembly inserted into the body from one end. The body includes a central cylindrical portion extending along a first axis, a tubular outlet portion extending along a second axis parallel to and offset from the first, so as to intersect the central portion only over a portion of the length of each, and a tubular inlet extending along a third axis perpendicular to the first axis and above the intersected portion thereof. An uninterruped 360.degree. band forming a seat remains between the outlet and the inlet. The plunger assembly includes a resilient, circumferential lip that engages the seat in the closed position of the valve, and a circumferential recess adjacent the lip, that permits fluid to flow through the valve in the open position.
