摘要：An angiographic injector system (10) includes a motor driven pump (18) whichdelivers radiographic contrast material to a catheter (30) at a variable flow rate which isinteractively controlled by a user. Operation of the pump (18) is controlled by the user,through a user actuated remote control (14). The angiographic system (10) also includesa manifold (26) and a valve which selectively connects either a syringe pump (18) or a lowpressure system (38) to a catheter (30) which is inserted into a patient. The valve isnormally biased to a state which connects the low pressure system (38) to the catheter(30) for pressure monitoring, saline flushing, or aspirating functions. When an injection isto be made, the valve automatically switches so that the low pressure system (38) isdisconnected and not exposed to high pressure, while the syringe pump (18) is connectedthrough the manifold (26) to the catheter (30).
