Abstract: A multi-fluid injector system having a powered injector having a housing enclosing at least one reciprocally operable piston is described. The injector system includes a multi-use disposable set (MUDS) connectable to the powered fluid injector. The MUDS has at least one syringe having a proximal end and a distal end and a plunger reciprocally movable by the at least one piston element within a syringe interior between the proximal end and the distal end; a manifold in fluid communication with the distal end of the at least one syringe; at least one valve in fluid communication with the syringe interior, the at least one valve operable between a filling position for filling the syringe interior with fluid and a delivery position for delivering the fluid from the syringe interior; and at least one connection port in fluid communication with the manifold and the syringe interior when the at least one valve is in the delivery position. The injector system further includes a coupling mechanism for operating the at least one valve between the filling position and the delivery position. Various features of the MUDS assembly and methods of interaction between the injector system and the MUDS assembly are also described.

Abstract: A syringe includes a barrel having a proximal end, a distal end, and a sidewall extending substantially circumferentially between the proximal end and the distal end along a longitudinal axis. The barrel is formed from an injection molding process including aligning a mold die defining an internal shape of the barrel in a molding cavity defining an external shape of the barrel, the molding cavity defined by first and second mold sections. Each mold section includes at least one gate adapted to control the flow of a molding material into the molding cavity. The gates of each mold section are opened to permit the first and second melt streams of molding material to fill the molding cavity surrounding the mold die, where the molding material takes the shape of the molding cavity.

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 multi-use disposable set (MUDS) has at least one syringe having a proximal end and a distal end spaced apart from the proximal end along a longitudinal axis. The MUDS further has a plunger reciprocally movable within a syringe interior between the proximal end and the distal end. A manifold is in fluid communication with the distal end of the at least one syringe. At least one valve is in fluid communication with the syringe interior. The at least one valve is operable between a filling position for filling the syringe interior with fluid and a delivery position for delivering the fluid from the syringe interior. At least one connection port is in fluid communication with the manifold and the syringe interior when the at least one valve is in the delivery position. A multi-fluid delivery system having the medical connector and MUDS is also provided. Various features of the MUDS system are also described.

Abstract: A connector assembly may include a body and a fluid fitting, the fluid fitting configured for releasably engaging a syringe nozzle, at least one deflectable locking arm connected to the body and radially deflectable relative to the distal end, the proximal end of the at least one deflectable locking arm configured for deflecting in a radial direction relative to the distal end to releasably engage the syringe nozzle, and at least one locking element disposed on the at least one deflectable locking arm, the at least one locking element movable with movement of the at least one deflectable locking arm between a first position where the at least one locking element is released from an engagement portion of the syringe nozzle and a second position where the at least one locking element is engaged with the engagement portion of the syringe nozzle.
