    摘要: A dual one-way check valve arrangement (300) that may be used for assessing an operating condition of at least one of first and second check valves (304, 308) situated in series along/within a section of a patient-specific section of tubing (244). A pressure sensor (332) may be associated with at least part of the flow path between the first and second check valves (304, 308) and may be operable to provide an indication of a failed condition of at least one of the first and second check valves (304, 308). In one embodiment, the pressure sensor (332) may change from a first state to a second state upon fluid pressure within the flow path between the first and second check valves (304, 308) falling below a predetermined level. For instance, the predetermined level may be a cracking pressure of at least one of the first and second check valves (304, 308). The change in state may be visually discernible on an exterior of the pressure sensor (332).

    摘要: In certain embodiments, a syringe mount of the invention may include a plate, an actuator, and one or more movable members located between the plate and the actuator. Each of the plate and the actuator may have an orifice defined therein, and an imaginary reference axis of the syringe mount may extend through one or both of these orifices. The actuator may be movable relative to the plate in a direction substantially perpendicular to the reference axis. Further, the moveable member(s) may be designed to move (e.g., pivot) toward the reference axis due to movement of the actuator from a first position to a second position and to move (e.g., pivot) away from the reference axis due to movement of the actuator from the second position to the first position.

    摘要: An injection device (120) used in delivering medical fluids to a patient is provided. The injection device (120) may include a syringe plunger driver (126a) and a syringe (140). The syringe (140) may include a syringe data storage device (134). The injection device (120) may include a communication device (132a) disposable in each of attached and detached conditions. The communication device (132a) may be operable to read a data storage device (134) within its field of view. When the communication device (132a) is attached to the injection device (120) and the syringe (140) is installed on the injection device (120), the communication device (132a) may be operable to read the data storage device (134) associated with the syringe (140). When in a detached condition, the communication device (132a) may be operable to be hand manipulated such that various other data storage devices (134) may be read.

    摘要: A syringe plunger drive assembly (132) for advancing a syringe plunger (90a/b) in at least one direction (e.g., to deliver fluid). In one embodiment, this syringe plunger drive assembly (132) may be constructed of all non-ferrous components and includes a piezoelectric pump (110) that supplies pressurized hydraulic fluid to a syringe plunger driver (134). The syringe plunger driver (134) may be in the form of a single acting hydraulic cylinder including a piston rod (140) movable in first and second generally opposing directions (e.g. forward and rearward). A valve (152) and a reservoir (154) may be fluidly interconnected between the piezoelectric pump (110) and the syringe plunger driver (134) to facilitate the pumping of hydraulic fluid to the syringe plunger driver (134).

    摘要: The disclosed embodiments provide for a syringe mount for a medical fluid power injector. The syringe mount is designed to hold a syringe so that a drive of the medical fluid power injector can move a plunger of the syringe to expel medical fluid from the syringe. The syringe mount comprises a first syringe clamp comprising a first arcuate surface, and a second syringe clamp comprising a second arcuate surface, wherein the first and second syringe clamps are in opposing relation to one another such that the first arcuate surface faces the second arcuate surface, and wherein the first and second syringe clamps are adapted to translate in opposite linear directions toward and away from one another to engage and disengage a syringe located therebetween.
