    Abstract: A pressure sensor for use with a fluid delivery system having good sensitivity at low pressure, but also configured to remain in operating condition after being exposed to high pressures is disclosed herein. In one variation, the pressure sensor includes a fluid path set, a deformable element associated with the fluid path set and configured to deform in response to an external pressure, and a pressure transducer for monitoring deformation of the deformable element. In certain embodiments, the pressure sensor is configured to measure fluid pressure within the range of between about 0 mm Hg to about 300 mm Hg. However, the sensor pressure is also be configured to remain functional after being exposed to pressure in excess of about 60,000 mm Hg.

    Abstract: A syringe includes a body and a plunger disposed therein. The body includes a nozzle formed therein and at least one hub member connected thereto or integrally formed thereon for holding an end of a connector tube. The connector tube includes two ends, each end preferably being connected to a respective hub member to retain the connector tube in contact with the syringe. Preferably, the syringe and the connector tube are packaged in a pre-connected condition for ease of use by the customer. Furthermore, flexible inlet tubing for connection to a syringe for filling the syringe with contrast media, for example, is described. The inlet tubing permits filling of the syringe from either a bag or a bottle and may remain attached to the syringe so that it forms at least a part of the connection to the patient. In addition, an apparatus for facilitating the purge of air from a connector tube that will ultimately be connected between a syringe and a patient is described. The apparatus includes a purging tube connected to the distal end of the connector tubing from the syringe. The purging tube includes a venting cap at its distal end. A flow inhibitor is positioned under the venting cap to cooperate with the venting cap by discouraging the discharge of fluid from the distal end of the purging tube while permitting the discharge of air therefrom.

    Abstract: An angiographic injector control system for delivering a controlled volume of injection fluid is described. The injector has a motor driven piston for ejecting fluid from a syringe cartridge contained within a pressure jacket. The drive motor is operated in accordance with a command voltage corresponding to an incremental position of the injector piston, the command position signal also corresponding to the volume of fluid to be ejected from the cartridge. This command position voltage signal is compared to an actual position voltage to produce an error signal for operating the drive motor, whereby the syringe piston follows the position command signal. Volume selector means produce a volume signal corresponding to a desired maximum volume of fluid to be ejected; this volume signal is compared to the sum of the position command increments, producing a stop signal when the position command signal equals or exceeds the volume limit signal. Thus, the injector control system regulates the injection of fluid by sensing and controlling the position of the injector piston.

    Abstract translation: 描述了用于输送受控体积的注射流体的血管造影注射器控制系统。 注射器具有用于从包含在压力套内的注射器药筒排出流体的马达驱动活塞。 驱动马达根据对应于喷射器活塞的增量位置的指令电压进行操作，指令位置信号也对应于从墨盒喷出的流体体积。 将该指令位置电压信号与实际位置电压进行比较，以产生用于操作驱动电动机的误差信号，由此注射器活塞跟随位置指令信号。 音量选择器意味着产生对应于要喷射的所需最大流体体积的体积信号; 该音量信号与位置指令增量的和进行比较，当位置指令信号等于或超过音量限制信号时产生停止信号。 因此，喷射器控制系统通过感测和控制喷射器活塞的位置来调节流体的喷射。

    Abstract: A high pressure medical connector tubing assembly includes a high pressure medical connector tubing assembly, including a tube element having opposed tube ends and a passageway, an end element overmolded to at least one of the opposed tube ends, the end element having an annular end portion having a preselected length, and a connector element having a connector hub defining a receiving cavity. The preselected length of the annular end portion may be used to pre-control the axial location of stress concentration in the connector hub. A method of forming the high pressure medical connector tubing assembly includes providing a tube element comprising opposed tube ends and a passageway therethrough, overmolding an end element onto at least one of the opposed tube ends, providing a connector element comprising a connector hub defining a receiving cavity, and securing the tube end with the overmolded end element in the receiving cavity.

    Abstract: Syringe systems and flow control systems configured to detect information associated with a liquid material are described. The syringe systems may include a syringe body for housing the liquid material and an injector piston for expelling the liquid material out of the syringe through a discharge outlet at a distal end of the syringe body. Components of the syringe, such as an injector piston, may include sensors configured to measure and/or detect a property of the liquid material, such as concentration, pH, or radioactivity. The flow control system may include a pinch valve and a platen arranged about a fluid delivery channel. Flow within the fluid delivery channel may be controlled by increasing (squeezing the fluid delivery channel) or decreasing the distance between the pinch valve and the platen. Components of the flow control system may include detectors configured to detect properties of fluid in the fluid control channel.

    Abstract: A pharmaceutical transport container includes a first body portion adapted to receive at least a portion of a pharmaceutical vial, a second body portion removably engaged with the first body portion to fully enclose the vial, and a flexible ring positioned in an interior cavity of the second body portion and configured to flex between a relaxed state and a radially-outward extended state. The pharmaceutical transport container may also include a removable end cap having a receiving chamber to receive the first body portion, and/or a guide tab extending from an exterior surface of the second body portion to engage a guide slot defined in a fluid injection system docking station, whereby the transport container translates axially and rotationally into the docking station to establish a fluid connection between the vial and a fluid connector mechanism or element disposed within the docking station.
