1. A fluid delivery system comprising:
- at least a first pump system to pressurize an injection fluid;
a patient interface in removable fluid connection with the first pump system; and
a fluid path in fluid connection between the at least first pump system and the patient interface, the fluid path comprising a connector comprising a housing defining at least one inlet and an outlet and a sealing member at least partially disposed within the housing, the sealing member being adapted to extend outward from an interior of the housing of the connector to be at least generally flush with the outlet of the connector to facilitate aseptic cleaning of an outward facing surface of the sealing member and being biased to close the outlet when the patient interface is disconnected from the connector, the at least first pump system being in fluid connection with the at least one inlet of the connector and the patient interface being in removable fluid connection with the outlet of the connector.

Abstract
A fluid delivery system for delivery of an injection fluid to a patient generally includes a pump system to pressurize the injection fluid, a patient interface in removable fluid connection with the pump system, and a connector in fluid connection between the pump system and the patient interface. The pump system is connected to an inlet of the connector, and the patient interface is removably connected to an outlet of the connector. The connector includes a sealing member at least partly disposed within a housing of the connector that is biased to close the outlet when the patient interface is removed.

removably connecting the patient interface to the outlet of the connector, whereby the patient interface opens the sealing member to create a fluid path from the first and second pump systems to the patient;
injecting fluid from the first and second pump systems into the patient;
disconnecting the patient interface from the connector;
aseptically treating the connector; and
connecting a new patient interface to the connector. - View Dependent Claims (25)

26. A fluid delivery system comprising:
-
at least a first pump system to pressurize an injection fluid;
a patient interface in removable fluid connection with the first pump system; and
a fluid path in fluid connection between the at least first pump system and the patient interface, the fluid path comprising a connector comprising a housing defining at least one inlet and an outlet and a sealing member at least partially disposed within the housing, the sealing member being biased to close the outlet when the patient interface is disconnected from the connector, the at least first pump system being in fluid connection with the at least one inlet of the connector and the patient interface being in removable fluid connection with the outlet of the connector, wherein an increase of pressure within the connector housing acts to improve a seal created by the sealing member when the patient interface is disconnected from the connector. - View Dependent Claims (27, 28, 29, 30, 31, 32, 33)
