  • Patent number: 8080001
    Abstract: In general, this disclosure relates to techniques for implementation and use of a fluid connection assembly, having a locking mechanism, which may be connected to a medical fluid injection device. An example fluid connection assembly includes at least one fluid connector, a mating mechanism coupled to the at least one fluid connector and configured to connect the at least one fluid connector to a medical fluid injection device, and a locking mechanism coupled to the mating mechanism and movable into a locked position or an unlocked position. In this example, the fluid connection assembly becomes affirmatively coupled with the medical fluid injection device when the locking mechanism is in the locked position, and the fluid connection assembly becomes removably decoupled from the medical fluid injection device when the locking mechanism is in the unlocked position.

  • Publication number: 20110179485
    Abstract: The invention relates to a method for recognizing attacks on at least one interface of a computer system, particularly a self-service machine, comprising: monitoring the interface in order to detect changes to the interface; if changes occur, the probability of an impermissible attack on the interface is determined based on the nature of the change; if the probability is above a defined threshold value, defensive measures are taken.

  • Publication number: 20110160581
    Abstract: In general, this disclosure relates to techniques for sealing, or pinching, high-pressure fluid tubing (e.g., braided tubing) that may be used to deliver medical fluid from a powered medical fluid injection device, such as an injector that delivers contrast media and/or saline during angiographic or computed tomography (CT) procedures. In some cases, one or more low-friction, solenoid-based pinch valve mechanisms may be used. One example powered medical fluid injection device comprises an injector head and at least one pinch valve mechanism that is coupled to the injector head. The at least one pinch valve mechanism comprises a plunger, a reciprocating arm driven by the plunger, and a tube pinching area. The at least one pinch valve mechanism, when deactivated by the injector head, is configured to cause the reciprocating arm to pinch fluid tubing that runs through the tube pinching area.

  • Publication number: 20110134246
    Abstract: A method and a device (DET) are proposed to defend against electronic spying during the transmission of image data (Sb) or image signals (Sa) that are generated by a camera (CAM) installed at a self-service terminal (ATM), said camera recording an area (A0) that covers an operating area of the self-service terminal (ATM). As soon as events occurring at the self-service terminal (ATM) in the recording area (A0) or outside of said area, in particular actuation of a key pad (KBD) and/or insertion of a card into a card slot (SLT), are detected, the generation of the image signals (Sa) and/or the transmission of the image data (Sb) is controlled as a function thereof, for instance at least the sensitive areas or partial image data (Sb?) in the image data obtained (Sb) are blanked out or replaced by artificially generated data.

  • Publication number: 20100113923
    Abstract: In general, this disclosure relates to techniques for providing a mating mechanism between at least one pressurizing unit and at least one corresponding sleeve in a powered medical fluid injection device. An example powered medical fluid injection device includes a sleeve and an injector head coupled to the sleeve. The sleeve has a notch with a predefined shape and size. The sleeve is configured to receive a pressurizing unit (such as a syringe) having an external tab with a predefined shape and size that are substantially identical to the predefined shape and size of the notch in the sleeve, such that the tab mates with the notch when the sleeve receives the pressurizing unit. The injector head is configured to inject a quantity of a medical fluid from the pressurizing unit during operation.
