A solution is proposed for operating an injection system comprising a pressurizing unit and at least one supply station for supplying a medical fluid to the pressurizing unit, the supply station comprising at least one receptacle for containing said medical fluid, a delivery arrangement in fluid communication with the receptacle and the pressurizing unit for delivering the medical fluid to a patient, and clamping means associated with the delivery arrangement for regulating the flow of the medical fluid through the delivery arrangement. The method comprises the steps of: operating the pressurizing unit till a first injection procedure is completed; maintaining the injection system in a standby condition before a second injection procedure is started, and operating the pressurizing unit till the second injection procedure is completed. The step of maintaining the injection system in a standby condition comprises the step of acting on the clamping means for de-clamping the delivery arrangement.

Method of operating an injection system

A solution for injecting one or more fluids into a patient is proposed. A corresponding injection system () comprises one or more supply stations () each one for supplying one of the fluids to be injected from a container (); at least one of the supply stations () comprises housing means () defining a chamber for housing the container (), the chamber having a connection port () for connecting the container () to a delivery arrangement () for delivering the fluid to the patient, and a conditioning device () for thermally conditioning the fluid in the chamber, wherein the conditioning device () comprises a first conditioning element () arranged around the connection port () and a second conditioning element () extending transversally to the first conditioning element ().

Thermal conditioning device for an injection system

A peristaltic pump () is proposed which comprises a first housing component () and a second loading component (), said second loading component being at least partially contained within said first housing component and being axially movable with respect to said first housing component inside thereto. The second loading component further comprises at least a couple of rollers () which engage and squeeze a delivery tube () for delivering a fluid passing there through when, in operation, the second loading component is fully snapped into said first housing component. Moreover the second loading component comprises a guiding path () for guiding the delivery tube around said at least a couple of rollers towards an exit port () which is provided at a distal end surface of the second loading component. The present invention also relates to a patient set and to an injection system comprising said peristaltic pump, as well as to a method of operating said injection system.

Injection system

A solution for injecting one or more fluids into a patient is proposed. A corresponding injection system () comprises one or more supply stations () each one for supplying one of the fluids to be injected, wherein at least one of the supply stations () comprises a bottle holder () for holding a bottle () containing the fluid to be injected, the bottle holder () comprising a first connector (), and a cover () for covering the bottle () when held on the bottle holder (), the cover () comprising a second connector () for mating with the first connector () to mount the cover () on the bottle holder (); said at least one supply station () further comprises a bag holder () for holding a bag () containing the fluid to be injected, the bag holder () comprising a further second connector () for mating with the first connector () to mount the bag holder () on the bottle holder () and a further first connector () for mating with the second connector () to mount the cover () on the bag holder ().
