摘要： An angiographic injector (10), preferably in the form of a dual port syringe , has an upper port (78) for connection to a fluid reservoir (22) and a lower port (80) for delivery of the medical fluid under pressure to a patient. A first valve (28) is connected between the fluid reservoir (22) and the upper port (78), and a second valve (26) is connected between the lower port (80) and the patient. During a fill operation, a piston (20) is moved within the syringe (18) to draw fluid from the reservoir (22) into the syringe (18) through the first valve (28) and the upper port (78). The first valve (28) permits air to be expelle d from the syringe (18) through the first valve (28) during a purge operation, but blocks flow of fluid the syringe (18) back to the fluid reservoir (22). During injection operation, the piston (20) moves in an opposite direction to force fluid out of the syringe (18) through the lower port (80).

摘要： An angiographic injector system includes a manifold (26) and valve which selectively connects either a syringe pump (18) or a low pressure system to a catheter (30) which is inserted into a patient. The valve is normally biased to a state which connects the low pressure system to the catheter for pressure monitoring, saline flushing, or aspirating functions. When an injection is to be made, the valve automatically switches so that the low pressure system is disconnected and not exposed to high pressure, while the syringe pump is connected through the manifold to the catheter.

摘要： An angiographic injector system (10) includes a motor driven pump (18) which delivers radiographic contrast material to a catheter (30) at a variable flow rate which is interactively 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 includes a manifold (26) and a valve which selectively connects either a syringe pump (18) or a low pressure system (38) to a catheter (30) which is inserted into a patient. The valve is normally 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 is to be made, the valve automatically switches so that the low pressure system (38) is disconnected and not exposed to high pressure, while the syringe pump (18) is connected through the manifold (26) to the catheter (30).
