Patent number: 8740877Abstract: 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.Type: GrantFiled: December 19, 2011Date of Patent: June 3, 2014Assignee: ACIST Medical Systems, Inc.Inventors: Tom Borlaug, Marty Hieb, Khoi Le, Chris Lins, Steven Paul Plager, Darryl T. Wrolson, Nathaniel R. Hallee, Paul Pilosi

Patent number: 8419676Abstract: 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.Type: GrantFiled: March 4, 2011Date of Patent: April 16, 2013Assignee: ACIST Medical Systems, Inc.Inventors: Alan Evans, Marty Hieb, Khoi Le, Chris Lins, Steven Paul Plager, Bill West, Darryl T.
