A multi-dose injection system ( 108 ) is disclosed that allows for safe and easy use of bulk containers, a multi-use tubing set ( 110 ), and syringes ( 86 a, 86 b ) across multiple patients. The bulk containers may include a saline bottle ( 118 ) and a contrast bottle ( 120 ) for administration to a series of patients undergoing imaging procedures. The bottles ( 118, 120 ) may be fluidly connected to a cassette ( 114 ) that includes a saline valve ( 176 ) and a contrast valve ( 178 ) operable to control flow from the saline bottle ( 118 ) and the contrast bottle ( 120 ), respectively. The cassette ( 114 ) may be fluidly interconnected to the multi-use tubing set ( 110 ) that is, in turn, fluidly connected to syringes ( 86 a, 86 b ) on a powerhead ( 50 ) and a patient-specific tubing set ( 112 ). The patient-specific tubing set ( 112 ) may be replaced between patients and may also serve to isolate the remainder of the multi-dose injection system ( 108 ) from contamination from bodily fluids. |
