    摘要： This invention relates generally to the field of Magnetic Resonance Imaging (MRI) systems for generating diagnostic images of a patient's internal organs and more particularly, this invention relates to improved MRI systems with decreased interference between the magnetic field used for producing diagnostic images and the magnetic fields generated by the electric motors used for driving the pistons of the contrast media injectors. Additionally, the system employs an improved communication link between an externally located system controller and the injection head control unit located within the electromagnetic isolation barrier which defines the magnetic imaging room.

    摘要： A luer connector is provided with a tactile and audible torque indicator. The indicator comprises a detent incorporated between the female cylindrical component of the luer connector and a rotatable collar mounted thereon. As the collar is turned in a clockwise direction, the collar is impeded by the detent formed by opposingly projecting protuberances between the inside of the collar and the outside of the female cylindrical luer component. As the threaded luer connection is tightened, requiring additional torque to tighten it further, the additional torque overcomes the resistance of the detent, allowing the collar protuberance to slip past the cylinder protuberance. The female luer component may also be provided with a color patch or pattern, to indicate by its rotation, when the detent has been overcome, that the luer connection has been appropriately tightened. In an alternative embodiment, oppositely disposed grooved wings are provided on the rotatable threaded collar of the male luer component to provide indication of proper torque by deflection and failure of the wings just prior to overtightening. The wings may be provided with gussets to strengthen the wings for rotation in the loosening direction.

    摘要： The fluid injection apparatus for use with the syringe includes an injector and a pressure jacket assembly associated with the injector. The injector includes a housing defining a central opening and a drive piston extendable through the central opening for imparting motive forces to a syringe plunger disposed within the syringe. The pressure jacket assembly includes a pressure jacket and at least one locking member pivotally associated with the pressure jacket. The at least one locking member is movable between an engaged position preventing removal of the syringe from the pressure jacket and a disengaged position allowing insertion and removal of the syringe into the pressure jacket.

    摘要： Apparatuses for supporting medical equipment are provided. Some apparatuses provide a support arm comprising a resilient assembly. The resilient assembly preferably comprises a detent and receives force imparted upon the support arm. Essentially, the assembly limits stress imparted upon the support arm and any other structure that the support arm is operatively connected to thereby making the apparatuses more durable. Another apparatus provides a collet for preventing a support arm from sliding from a housing. Yet another apparatus provides spacers than can be used to virtually extend the length of a support arm. Methods of adjusting a support arm are also provided.

    摘要： The present invention provides a plunger for use in a syringe and a syringe comprising such a plunger. The plunger includes a pressure member extending around the circumference of a generally cylindrical body of the plunger. The pressure member is in substantially sealing contact with the plunger body. The pressure member is sufficiently flexible to be forced radially outwardly to exert force upon the inner wall of the syringe as a result of increased fluid pressure upon forward motion of the plunger. The pressure member thereby forms a substantially sealing engagement with the inner wall of the syringe. In one embodiment, the pressure member comprises a flange attached at a rearward portion of the flange to a body of the plunger. The flange extends forward and radially outward to form a circumferential channel between the flange and the body of the plunger. In another embodiment, the pressure member comprises a resilient O-ring seated in a seating formed around the circumference of the body of the plunger. The seating comprises a ramp portion having a forward radius that is smaller than a rearward radius thereof.

    摘要翻译： 本发明提供一种用于注射器的柱塞和包括这种柱塞的注射器。 柱塞包括围绕柱塞的大致圆柱形主体的圆周延伸的压力构件。 压力构件与柱塞本体基本上密封接触。 由于柱塞向前运动时的流体压力增加，压力构件足够柔软以被迫径向向外施加到注射器的内壁上。 因此，压力构件与注射器的内壁形成基本密封的接合。 在一个实施例中，压力构件包括在凸缘的后部附接到柱塞的主体的凸缘。 凸缘向前并径向向外延伸，以在凸缘和柱塞主体之间形成圆周通道。 在另一个实施例中，压力构件包括位于围绕柱塞主体的圆周形成的座中的弹性O形环。 座椅包括具有小于其后半径的前半径的斜坡部分。
