Multiple fluid delivery system with multi-use disposable set and features thereof
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.
1. A multi-fluid injector system, comprising:
a powered injector comprising a housing enclosing a plurality of reciprocally operable piston elements;
a receiving space configured for removably receiving a plurality of syringes of a multi-use disposable set (MUDS), the receiving space comprising a bottom plate and a top plate spaced apart from the bottom plate by a rear sidewall such that the plurality of syringes of the MUDS are supported axially between the top plate and the bottom plate; and
at least one guide associated with the receiving space,
wherein the at least one guide narrows in an insertion direction toward the rear sidewall to guide the MUDS into the receiving space, and
wherein the top plate defines a plurality of slots configured for receiving at least one of the plurality of syringes of the MUDS, and wherein each of the plurality of slots defines a mating recess for receiving a conical distal end of the at least one syringe such that the conical distal end engages the mating recess when the MUDS is received in the receiving space.
2. The multi-fluid injector system of claim 1 , wherein the MUDS is configured for connecting with a plurality of bulk fluid sources.
3. The multi-fluid injector system of claim 1 , wherein the top plate is movable between a first position configured for insertion and removal of the MUDS within the receiving space and a second position configured for locking the MUDS within the receiving space.
4. The multi-fluid injector system of claim 3 , wherein the top plate comprises at least one latch for locking the top plate in the second position.
5. The multi-fluid injector system of claim 1 , further comprising at least one coupling configured for engaging at least one valve on the MUDS.
6. The multi-fluid injector system of claim 5 , wherein the at least one coupling is a rotatable coupling having a blade configured for self-alignment with a slot formed on the at least one valve on the MUDS.
