1. A fluid management system comprising:
- a primary fluid container;
a secondary fluid container;
a sterile fluid disposed in said primary fluid container for transfer to said secondary fluid container;
a fluid flow input line connecting said primary and secondary fluid containers;
a fluid flow control member provided in the fluid flow input line between said primary and secondary fluid containers to interrupt fluid flow from said primary to said secondary fluid container;
a one way fluid flow control device disposed in the fluid flow input line between the primary fluid container and the fluid flow control member to prevent fluid return from the secondary fluid container to the primary fluid container thereby providing a sterile barrier for the primary fluid container;
at least one external fluid flow control member provided on the fluid flow input line for controlling fluid flow through the one-way fluid flow control from the primary fluid container to the secondary fluid container and operable to terminate fluid flow;
a disconnect member in the fluid input line engageable with the one way fluid flow control device thereby enabling the disconnection of the primary fluid container from the secondary fluid container without loss of fluid; and
a sterile cap engaging the disconnect to preserve the sterile barrier for the primary fluid container thus to permit the use of the single container of fluid held in the primary fluid container in a second procedure with another secondary fluid container, thus to minimize waste and to maintain sterility in the primary fluid container.

Abstract
An apparatus wherein the primary dye container is connected to a secondary dye container with sufficient safeguards, including at least one-way check valve and at least one stopcock between the primary dye container and the secondary dye container, to assure a sterile barrier between the primary and secondary dye sources so that less than the total amount of sterile contrast media can be transferred from the primary dye container in an amount sufficient to perform a cardiac catheterization procedure.

12. A fluid management system comprising multiple primary fluid containers;
-
a secondary fluid container; a sterile fluid disposed in said primary fluid containers for transfer to said secondary fluid container; respective primary fluid input lines connecting each of said primary fluid containers to the secondary fluid container; a fluid flow control member provided in each of the primary fluid input lines between a respective primary fluid container and said secondary fluid container to interrupt fluid flow from said primary to said secondary fluid container; a connector connecting each of said primary fluid input lines to a secondary fluid container input line, to direct flow from each of the primary fluid containers to a single secondary fluid input line; a one-way fluid flow control device disposed in the secondary fluid flow input line between the primary fluid containers and the secondary fluid container to prevent fluid return from the secondary fluid container to the primary fluid containers; at least one external fluid flow control member provided on the single secondary fluid input line for controlling fluid flow from the primary fluid containers to the secondary fluid container; a disconnect member in the secondary fluid flow input line; a fluid flow control member engageable with the disconnect member in the secondary fluid flow input line, the one-way fluid flow control device providing a sterile barrier for the primary fluid containers, the external fluid flow control member operable to terminate fluid flow to enable the disconnection of the secondary fluid container from the primary fluid containers without loss of fluid; and a sterile cap engaging the disconnect member to preserve the sterile barrier for the primary fluid containers, thus to permit the use of the single source of medical fluid in said primary fluid containers in a second procedure with another secondary fluid container, thus to minimize waste while maintaining sterility in the primary fluid containers. - View Dependent Claims (13, 14, 15, 16)

17. A method of transferring a sterile fluid from a primary fluid container to a secondary fluid container in a fluid management system comprising at least one primary fluid container, a secondary fluid container, a sterile fluid disposed in said primary fluid container for transfer to said secondary fluid container, and a fluid input line connecting said primary and secondary fluid containers and maintaining a sterile barrier within said primary container before, and during and after fluid transfer, including disconnection of said secondary container therefrom, the method comprising:
-
disposing a fluid flow control member in the fluid flow input line between said primary and secondary fluid containers to interrupt fluid flow from said primary to said secondary fluid container; disposing a one-way fluid flow control device in the fluid flow input line between the primary fluid container and the secondary fluid container to prevent fluid return from the secondary fluid container to the primary fluid container and to provide a sterile barrier for said primary container; enabling the disconnection of the primary fluid container from the secondary fluid container; and capping the fluid input line connected to the primary fluid container to maintain the sterile barrier for the primary fluid container to permit the use of the sterile fluid in the primary fluid container in a second procedure with another secondary fluid container, thus to minimize waste and to maintain sterility in the primary fluid container.
