Abstract: A needleless connector has a body having an internal cavity with a sealing ridge, a port, an output flow channel, and a fluid flow path between the port and output flow channel. The connector also has a collapsible valve disposed within the cavity. The valve includes a cylindrical wall having a center axis, an internal surface, and a shoulder configured to sealingly contact the ridge of the body, thereby blocking the fluid flow path. The valve also includes a head fixedly attached to the wall. The head has a smiley cut at a first angular position about the center axis and a continuous top surface that is generally perpendicular to the axis. The valve also includes a dimple formed in the internal surface of the cylindrical wall. The dimple extends around the internal surface over an angle.

Abstract: Described is a priming device to prime a gas from a fluid delivery system by receiving the gas and a fluid used to push the gas into a chamber, the priming device including a housing having a chamber, an inlet port, and an opening to release gas received into the chamber. The device further includes a valve extending from the inlet port toward the chamber and a cover body comprising one or more flexible protrusions extending axially inward from an inner surface of the cover body. The cover body has an open first end, an open second end, and an axis between the first end and the second end, the first end configured to couple with a male luer connector, the second end configured to couple with the inlet port of the housing, wherein the cover body is moveable relative to the housing.

Abstract: A priming system including a resilient chamber having flexible walls and a first check valve in a first fluid pathway between the resilient chamber and a fluid reservoir such that a fluid flows through the first check valve only in a direction from the fluid reservoir toward the resilient chamber and the fluid returns to the fluid reservoir through a second fluid pathway between the resilient chamber and the fluid reservoir upon compression of the walls of the resilient chamber.

Abstract: A cap for coupling to a medical adapter may include a housing with a closed top end and an open bottom end with legs that extend from the housing away from the bottom end. Members may extend from an inner surface of the legs to engage and secure the cap to a medical adapter or an insert configured to mate with a medical adapter. A cap may include angular ridges between a cap housing and an insert to permit rotation of the cap in single direction and prevent removal of the cap from a medical adapter. A cap may include hinged legs to permit the cap to be secured to a medical adapter by rotating the legs toward each other until a portion of a collar on each leg may be matingly joined around the medical adapter.

Abstract: A connector for transferring fluid and method therefor. The connector may have a first port and a second port which may be coupled together at a main channel with a valve element therein controlling fluid flow through the first port. The first port joins the main channel to provide a fluid path around the valve element and through the second port.

Abstract: Described is a priming device to prime a gas from a fluid delivery system by receiving the gas and a fluid used to push the gas into a chamber, the priming device including a cover body having a lid, and a housing having a chamber, an inlet port and an opening to release gas received into the chamber. The device has a priming-ready configuration where the medical connector and the housing are coupled with the cover body, and the fluid path of the medical connector and the passage of the housing remain sealed, a priming configuration where the medical connector is advanced in the cover body to fluidly couple with the housing, and a post-priming configuration where the housing is decoupled from the cover body and the lid closed to prevent contamination of the medical connector.

Abstract: A needleless connector has a housing with an internal cavity having an interior surface, a port, an output flow channel, and a fluid flow path through the cavity between the port and the output flow channel. A collapsible valve is disposed within the cavity. The valve has one or more rings each having a surface that is in sealing contact with the interior surface of the housing. There are one or more notches formed in each of the one or more rings, and the flow path passes through one of the notches in each of the one or more rings.

Abstract: A medical connector can include a body having a fluid path with an inlet port, an outlet port, a luer portion, and a post extending through a fluid path. An arm having a latch member is coupled to the body to engage a ridge or thread on an exterior surface of a reciprocal connector. The arm may also include an extension. When the connector is in an open position, the latch member restricts retraction of the reciprocal connector from the outlet port. A seal is coupled to the body and includes a flap extending across the outlet port or a bellows to compress along an axis. In a closed position, the post restricts flow through the luer portion. In an open position, the post permits flow through the luer portion.
