  • Publication number: 20230347760
    Abstract: The electrical connector comprises at least one contact terminal, a printed circuit board on which at least one thermal sensor is mounted to monitor the temperature of the at least one contact terminal, at least one thermal conductive pad that includes at least one first thermal contact surface in direct engagement with the at least one contact terminal, and a second thermal contact surface in direct engagement with the at least one thermal sensor, to transfer heat from the at least one contact terminal to the at least one thermal sensor, and a support device for the at least one thermal conductive pad. The at least one thermal conductive pad is compressed between the support device and the printed circuit board by a force of compression causing the at least one first thermal contact surface to press against the at least one contact terminal and the second thermal contact surface to deform on the thermal sensor covering the thermal sensor.

  • Patent number: 9308316
    Abstract: Various structures are used in a front-loading injector, for mounting the syringe to the injector and/or preventing leakage of spilled fluid from an external surface of a syringe into the vicinity of the drive ram. A conically-shaped structure on the rearward end of the syringe is specifically disclosed.

  • Patent number: 8932255
    Abstract: Various sealing structures are used in a front-loading injector, for preventing leakage of spilled fluid from an external surface of a syringe into the vicinity of the drive ram. For example, a sealing gasket may be incorporated into the front face of the injector housing, for mating to the rearward circular edge of the cylindrical body of a syringe. Alternatively, sealing and locking functions may be performed by a single structure on the rearward end of the syringe. Further, leakage may be prevented by including a non-planar sealing flange on the syringe, positioned on the syringe forward of the locking structure, or by a two-piece structure, including a syringe and a separate leakage stopping washer for surrounding the syringe to halt the flow of fluid along the exterior of the syringe. (As part of this aspect, or as an independent feature, the syringe may include an annularly discontinuous flange forward of the locking structure, for providing mechanical support for the syringe against the injector.

  • Patent number: 8038455
    Abstract: A connector assembly includes a retractable stabilizer moveable between a blade alignment position and a seated position in a shroud of a male connector. The retractable stabilizer is in the blade alignment position when the connector assembly is unmated and in the seated position when the connector assembly is mated. The retractable stabilizer includes a base and at least one position arm, at least one retention feature, and a securing member that extend from the base. When the connector assembly is unmated, the female connector pulls on the securing member which draws the retractable stabilizer to move from the seated position back towards the blade alignment position. When the at least one retention feature engages a blocking feature on the shroud, the at least one position arm flexes into at least one aperture defined in the shroud to secure the retractable stabilizer at the blade assembly position for reuse.

  • Publication number: 20080108896
    Abstract: A contrast media injection system detects the absolute position of the syringe ram using a non-contact sensor. A series of magnets and Hall-Effect sensors may be used or an opto-reflective system. Illuminated knobs that are connected to the drive mechanism for the syringe ram rotate with the drive and provide visual feedback on operation through the illumination. Analog Hall-Effect sensors are used to determine the presence or absence of magnets that identify the type of faceplate being used. The faceplates include control electronics, connected to the powerhead through connectors, which may be interchangeably used by the two faceplates. The faceplate electronics include detectors for automatically detecting the capacity of pre-filled syringes.
