The check valve further includes a valve member mounted in the cavity to selectively permit fluid flow in a first direction, and prevent fluid backflow in a second direction opposite to the first direction. The valve member includes a valve body and a valve stem portion extending axially through a central axis of the valve body.

A valve member for a connector includes a head portion, a body portion, and a circumferential lip seal extending radially outward from an outer surface of the head portion. The head portion includes a top section defining a first seal portion. The body portion extends longitudinally from the head portion and defines a second seal portion at a proximal end thereof. The second seal portion is disposed distally to the first seal portion. The circumferential lip seal is disposed between the first and second seal portions.

A connector comprises a body having a tubing portion and a luer portion axially opposite the tubing portion and connected thereto, an internal passageway defined by an inner circumferential surface of the connector, the passageway extending axially between the tubing portion and the luer portion and in fluid communication therewith, a stopping mechanism disposed in the luer portion and configured to limit an extent of a fluid line disposed in the connector, and a retaining mechanism disposed in the tubing portion and configured to retain the fluid line in the connector.

Luer having tubing retention pocket bond

A connector includes an outer housing defining a lumen, a first male coupler mateable with a needle-free valve and positioned at a first end of the outer housing, a second male coupler positioned at a second end of the outer housing, a valve system to control fluid flow through the lumen, and an actuator movable within the outer housing between a first position and a second position. A pinch clamp of the connector operates to selectively deflect locking fingers of the actuator from a locked position to a movement position to selectively enable or prevent movement of the actuator from the first position to the second position. The actuator, based on its positioning in the first or second position, causes the valve system to be in a closed state or an open state and blocks or allows the first coupler to couple with the needle-free valve.

Force-controlled release connector with integrated safety features

A coupler may include a coupler body including a first end, a second end, an outer surface, an inner surface defining a cavity, and a wall defined between the inner and outer surfaces, a plurality of first retaining fingers disposed adjacent to the first end and extending radially inward into the cavity, and a mounting aperture defined between a free end of each first retaining finger and the wall. The cavity may be configured to receive a first connector and a second connector. The plurality of first retaining fingers may be radially biased inward toward the cavity and configured to engage against a collar of the first connector to prevent axial motion of the first connector relative to the coupler. The mounting aperture may be configured to receive a pivot shaft of the collar to pivotally couple the first connector relative to a central axis of the coupler body.

Connector coupling assembly

Couplers are described herein. A coupler includes a coupler body, a plurality of first retaining fingers, and a plurality of second retaining fingers. The coupler body includes a first end and a second end, and defining a cavity, the cavity configured to receive a first connector and a second connector. The plurality of first retaining fingers are configured to engage against a collar of the first connector to prevent axial motion of the first connector relative to the coupler. The plurality of second retaining fingers are configured to engage against a shoulder of the second connector with a retention force, and release the second connector by radially expanding in response to a pullout force exerted on the second connector exceeding the retention force.

Vented syringes are described herein. A vented syringe includes a syringe body and a plunger body. The syringe body defines a syringe cavity. The plunger body is at least partially disposed within the syringe cavity. The plunger body includes an air intake channel defined within the plunger body. The vented syringe further includes a plunger seal that is sealingly engaged with the syringe cavity to cooperatively define a syringe volume. The vented syringe further includes a one-way valve in fluid communication with the air intake channel and the syringe volume, wherein the one-way valve is configured to prevent fluid flow from the syringe volume to the air intake channel and permit fluid flow from the air intake channel to the syringe volume.

Vented syringe

Check valve are disclosed having a primary seal and a secondary seal, where the primary and secondary seals resist movement of a fluid through the check valve, and the secondary seal can provide a backup seal in an instance where the check valve does not function as intended. The primary and secondary seals can be formed by first and second sealing ridges, respectively, and a valve body can be positioned within the check valve, between a valve support, the first sealing ridge, and a second sealing ridge. The valve body is configured to move relative to the first and second sealing ridges, and can have a position wherein a portion of the valve body is engaged against any of the first and second sealing ridges.

Check valve with secondary backflow seal

An apparatus for coupling to a fluid delivery system and for receiving a fluid into the apparatus; a portion of the apparatus permitting a change in shape or size to accommodate the fluid volume or pressure received therein. The apparatus including a housing with a cavity, an expandable reservoir with an opening and a passage, and a cap; the expandable reservoir positioned within the cavity and coupled to a fluid source. The expandable reservoir includes an unrestrained orientation when a fluid volume or pressure therein is below a threshold, and an expanded orientation, when the fluid volume or pressure therein is above the threshold; the expandable reservoir moving toward the expanded orientation to accommodate a fluid volume or pressure received through an opening, and the expandable reservoir moving toward the unrestrained orientation to direct a fluid volume or pressure through an opening.

Pressure spike absorbing systems

A connector is disclosed that includes comprising a body having a tubing portion, a luer portion axially opposite the tubing portion and connected thereto, and an inner circumferential surface defining an internal bore of the connector. The inner circumferential surface extends axially between the tubing portion and the luer portion, and the internal bore being is in fluid communication with the tubing portion and the luer portion. The inner circumferential surface includes a plurality of splines extending axially along a length of the inner circumferential surface in the tubing portion of the connector. The inner circumferential surface is configured to engage an external surface of a tubing in a coupled configuration. In the coupled configuration edges of the splines grip and engage the external surface of the tubing to retain the tubing in the body.

Luer having microbore tubing retention pocket bond with axial spline

A needleless connector may include a housing having an inlet port, an outlet port, and an inner surface defining an internal cavity extending between the inlet and outlet ports, and a compressible valve reciprocally disposed within the internal cavity. In a closed state, a top section of a head portion of the compressible valve may have a planar shape configured to contact and seal against the inner surface of the housing. In an open state, where the compressible valve is subject to an axial force, the top section of the head portion may be lodged between two pinch points between opposing walls of an inwardly angled portion of the internal surface. Additionally, in the open state, the top section of the head portion may have a non-planar shape defining a fluid path extending at least partially between opposing walls on an outwardly angled portion of the internal surface.
