20110184281 | INJECTOR - An injector automatic limiting of the operating pressure of the injector as determined by the selection of a flow rate; a syringe cradle having a warming capability; a purge/retract trigger for control of the injection procedure having intuitive direction (i.e., forward for injecting, reverse for filing), non-contact control transmission through the housing of an injector for an improved seal integrity, a speed lock, and/or the ability to change the concentration and/or flow rate of media or other fluid during an injection procedure; a switch to determine when the drive ram is in a “home” position; a “soft” on/off power switch separate from the injector; and a structure to prevent rotation of the drive ram about its axis of symmetry. Additionally, the injector system includes software for the control of various components. | 07-28-2011 |

20080306443 | Medical Fluid Injector Having Wireless Pressure Monitoring Feature - The present invention relates to medical fluid injectors. An exemplary injector may include a drive ram that is adapted to interface with a plunger of a syringe. The drive ram may be equipped with an RF enabled pressure sensor that is configured to measure pressure exerted on the syringe plunger by the drive ram. In addition, the injector may include an RF circuit in RF communication with the pressure sensor of the drive ram. In some embodiments, the injector may include a controller in electrical communication with the RF circuit. The controller may be configured to adjust movement of the drive ram to alter the pressure exerted on the syringe plunger by the drive ram (i.e., the pressure measured by the pressure sensor). | 12-11-2008 |
20090069747 | Power Injector with Movable Joint-Integrated Signal Transmission Connector - A power injector that incorporates at least one signal transmission connector in a movable joint (e.g., between a powerhead and a support or stand; between at least one adjacent pair of support sections of a support for the powerhead) is disclosed. Such a signal transmission connector may be in the form of a slip ring module, but in any case is part of the signal transmission link to the powerhead. At least that portion of a signal transmission conduit that is adjacent to the powerhead may be disposed within the interior of the corresponding portion of the support or stand, thereby reducing the potential that an individual will grab onto the signal transmission conduit when attempting to move at least part of the power injector, to change the position of the powerhead, or both. | 03-12-2009 |
20100004534 | Medical Fluid Injector Having a Thermo-Mechanical Drive - A medical fluid injector and methods for operation thereof. In certain embodiments, the medical fluid injector includes a medium that is expandable and contractible in response to a thermal gradient, a thermal device coupled to the medium, and a syringe interface coupled to the medium. The thermal device may include a heater, a cooler, or a combination thereof. | 01-07-2010 |
20100030153 | Injector Having Low Input Power - A powered injector that stores energy at a low rate when not in use and delivers energy at a high rate during injection. Energy may be stored in a highly responsive energy storage device, such as a capacitor, for rapid delivery of power to the injector motor. In certain embodiments, wires connecting the powered injector to a power supply may be relatively small and inexpensive because the current and voltage loads placed on the wires are relatively low. | 02-04-2010 |
20110060217 | POWERHEAD OF A POWER INJECTION SYSTEM - A contrast media injection system includes 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. Additional features include using historical data to provide optimum pressure limit values during an injection protocol, a removable memory device for storing and transferring information such as injection protocols and injector statistics, and password protection of such protocols. | 03-10-2011 |
20110060219 | POWERHEAD CONTROL IN A POWER INJECTION SYSTEM - A dual head contrast media injection system performs a patency check or test injection, determining flow rate and/or flow volume from the programmed protocol. The tubing that connects syringes to a patient shares only a short common section near to the patient. Appropriate injection steps are taken to compensate for tubing elasticity. A wireless remote control and a touch screen control are provided, improving functionality and information delivery. The display brightness is controlled based on the ambient light, and the display panel includes a double swivel permitting re-orientation. The orientation of the display may also be controlled based on, e.g., the current step, the tilt angle of the powerhead, or a manual control. Furthermore, the display is customizable to identify the type of fluid (contrast, saline, etc.) on either side of the injector, to provide matched color coding, and to provide a folder/tab analogy for retrieving injection protocol parameters. | 03-10-2011 |

The pressure developed by the remote provides tactile feedback to an operator for improved control over injections. | 06-07-2012 |
