Patent ID: 8812082

Claim:
A method comprising: obtaining operational state information of a powered medical fluid injection device that is operatively coupled to a first pressurizing unit and also to a second pressurizing unit, the operational state information including information, other than a fluid delivery amount for a subsequent injection procedure, to describe an operating state or condition of the powered medical fluid injection device; using the operational state information to determine whether the powered medical fluid injection device permits an automatic fluid replenishment operation for at least one of the first pressurizing unit and the second pressurizing unit; and if the fluid replenishment operation is permitted for the first pressurizing unit, the method further comprises: initiating the fluid replenishment operation in order to automatically supply the first pressurizing unit with medical fluid without any manual interaction by a user with the powered medical fluid injection device; after initiation of the fluid replenishment operation, and while the first pressurizing unit is being supplied with the medical fluid, obtaining additional operational state information that is generated based on a manual interaction by the user with a control panel of the powered medical fluid injection device, wherein the additional operational state information specifies that the powered medical fluid injection device is to initiate a new injection procedure using the medical fluid of the first pressurizing unit; after obtaining the additional operational state information, determine, based on the additional operational state information, that the powered medical fluid injection device will no longer permit the fluid replenishment operation for the first pressurizing unit; upon determining that the fluid replenishment operation is no longer permitted, automatically terminating, without any manual interaction, the fluid replenishment operation for the first pressurizing unit; and after terminating the fluid replenishment operation, initiating the new injection procedure, specified by the additional operational state information, using the medical fluid of the first pressurizing unit.
