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.
