The injector includes a housing defining an opening for a drive piston extendable from the housing. The pressure jacket secures the syringe during an injection procedure. The pressure jacket has a distal end defining a syringe receiving opening for receiving the syringe, and a proximal end associated with the housing and generally aligned with the opening. The apparatus includes a syringe sensor adapted for engagement by the syringe when loaded into the pressure jacket. The housing may have an engagement tab adapted to engage an engagement recess in the pressure jacket to removably engage the pressure jacket with the housing. The apparatus may have one or more light sources associated with the housing for illuminating the syringe received in the pressure jacket.

摘要： The control device is used to control delivery of fluids from a multi-fluid delivery system during a medical injection procedure. The fluid delivery system includes an injector used to deliver injection fluids to a patient. The control device is operatively associated with the injector for controlling discrete flow rates of injection fluids delivered to the patient. The control device includes a housing, first and second actuators associated with the housing, and an electronic substrate disposed within the housing and having a conductive pattern. The first actuator is operatively associated with the conductive pattern. The conductive pattern includes a plurality of predetermined digital values corresponding to discrete flow rates of injection fluids to be delivered by the injector. The second actuator is operatively associated with the electronic substrate and initiates output signals to the injector corresponding to desired mixture ratios of the injection fluids to be delivered by the injector.

摘要： A fluid injection system may include an injector, a syringe and an anti-rotation connection. The injector may have a drive piston having a plunger engaging end and the syringe may have a body and a plunger within the body. The plunger may have a proximal end with at least one coupling member adapted for engagement by the plunger engaging end. The anti-rotation connection may be formed by complementary anti-rotation elements associated between the proximal end of the plunger and the plunger engaging end of the drive piston to limit rotation of the plunger within the syringe body. The anti-rotation elements may include the at least one coupling member engaged in a radial groove defining at least one axial edge formed on the plunger engaging end to enable limited rotational movement of the plunger relative to the drive piston when the complementary anti-rotation elements are engaged.

摘要： A multi-fluid injector system and methods of operation thereof are presented. One embodiment of such a fluid injector system includes a powered injector, a pressure jacket support, a syringe pressure jacket, and a syringe. The pressure jacket support includes a front plate and a rear plate. The rear plate is connected to the injector and the front plate is spaced from the rear plate and defines a slot. The syringe pressure jacket has a proximal end pivotally connected to the rear plate so that a distal end of the pressure jacket pivots relative to the front plate. The syringe has a syringe body with a distally extending discharge conduit. With the syringe disposed in a barrel of the pressure jacket, pivotal movement of the pressure jacket results in the distal end thereof pivoting toward the front plate to place the discharge conduit within the slot in the front plate.

摘要： A syringe includes a body having a distal end, a proximal end and a center section therebetween. The distal end of the syringe body includes a conical portion that extends and tapers from the center section to an injection neck forming a discharge outlet. The proximal end of the syringe body includes a radial expansion section and an outward extending lip. An inner diameter of the radial expansion section is larger than an inner diameter of the center section and the outer diameter of the radial expansion section is smaller than an outer diameter of the center section. A plunger is movably disposed in the syringe body and includes a pair of coupling members defining a slot therebetween, the plunger being substantially seated in the radial expansion section in a pre-use state of the syringe. An alignment flange is formed on the conical portion and extends the distance between the center section and the injection neck. The alignment flange defines an internal hollow area therein in fluid communication with the interior of the syringe body, which is adapted to collect air bubbles that are present within the interior of the syringe body.
