Abstract: A fluid control valve for use in a fluid delivery system for delivering fluid to a patient includes a valve body defining an internal chamber, a first inlet port for receiving a first inlet tube, a second inlet port for receiving a second inlet tube, an outlet port, and a sliding valve member slidably disposed in the internal chamber. The first inlet tube defines a first inlet lumen axially aligned with the internal chamber. The second inlet tube defines a second inlet lumen axially aligned with the internal chamber. The sliding valve member includes a first sealing end and second sealing end. The sliding valve member is positionable in a first operating state, a second operating state, and a third operating state based on a flow differential between the first inlet lumen and the second inlet lumen.

Abstract: A fluid mixing device for mixing a first injection fluid and a second injection fluid includes a first fluid inlet, a second fluid inlet, a mixing chamber in fluid communication with the first and second fluid inlets, and an outlet port in fluid communication with the mixing chamber. The first fluid inlet is configured to conduct the first injection fluid in a first direction and has a first redirecting surface. The second fluid inlet is configured to conduct the second injection fluid in a second direction along a different axis from the first direction and has a second redirecting surface. The mixing chamber is configured to mix the first injection fluid and the second fluid together. The mixture of the first injection fluid and the second injection fluid exits the fluid mixing device via the outlet port.

Abstract: A plunger for use with a syringe has a plunger body with a proximal end, a distal end, and a circumferential sidewall extending between the proximal end and the distal end along a plunger longitudinal axis. The plunger further has at least one resiliently deflectable retaining member having a first segment attached to the plunger body and a second segment protruding toward the distal end of the plunger body and deflectable relative to the first segment. The plunger further has at least one actuation member associated with the at least one resiliently deflectable retaining member. The at least one actuation member interacts with a piston to deflect the at least one resiliently deflectable retaining member upon rotation of the plunger relative to the piston. The plunger is engageable with the piston regardless of a rotational orientation of the piston relative to the plunger.

CPC classification number: A61M5/365 , A61M5/007 , A61M5/14546
Abstract: An apparatus (300) for suspending air bubbles in a fluid path of a fluid injector system includes an internal chamber (320) having a curved interior wall (322) defined within the housing (310), an inlet fluid pathway in fluid communication with the internal chamber, and an outlet fluid pathway in fluid communication with the internal chamber. The inlet fluid pathway extending into the chamber at a tangent to the curved interior wall, and the outlet fluid pathway spaced from the inlet fluid pathway such that fluid flowing into the internal chamber via the inlet fluid pathway is directed away from the outlet fluid pathway. The internal chamber is configured to create an internal fluid vortex in an injection fluid entering the internal chamber from the inlet fluid pathway, and wherein the internal fluid vortex at least temporarily suspends air bubbles in the fluid in the internal vortex and delays the passage of the air bubbles to the outlet fluid pathway.

Abstract: An engagement mechanism associated with a reciprocally movable piston of a fluid injector is configured for releasably engaging an engagement portion at a proximal end of a rolling diaphragm syringe having a flexible sidewall configured for rolling upon itself when acted upon by the piston. The engagement mechanism has a plurality of engagement elements reversibly and pivotally movable about a pivot pin relative to the engagement portion of the syringe between a first position, where the plurality of engagement elements are disengaged from the engagement portion of the syringe, and a second position, where the plurality of engagement elements are pivotally movable about the pivot pin in a radially inward direction to engage with the engagement portion of the syringe. The engagement mechanism further has a drive mechanism for moving the plurality of engagement elements between the first position and the second position.
