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.

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.

Publication number: 20110064548Abstract: A post extending from a medical device facilitates transfer of the device between first and second support structures. Each of the first and second structures includes a mounting receptacle, configured to receive the post, fitting either tightly or loosely thereabout, depending on a position of the post along an axis of the receptacle. When the first receptacle holds the post and is moved in a first direction, the post may be moved into the second receptacle, which is then moved in a second direction, to tighten the second receptacle and loosen the first receptacle about the post. When the second receptacle holds the post, the first receptacle may be moved in the first direction, until the post enters the first receptacle, and, then, the second receptacle may be moved in a direction opposite to the second direction, to loosen the second receptacle and tighten the first receptacle about the post.Type: ApplicationFiled: September 17, 2009Publication date: March 17, 2011Applicant: ACIST MEDICAL SYSTEMS, INC.Inventors: Darryl T.

Publication number: 20100113923Abstract: 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.Type: ApplicationFiled: October 30, 2008Publication date: May 6, 2010Applicant: ACIST Medical Systems, Inc.Inventors: Marty Hieb, Khoi Le, Bill West, Darryl T.

Patent number: 5123000Abstract: An optical disk cartridge handling apparatus for storing, handling, reading and writing of optical disks contained in cartridges which store data for a host computer. The apparatus comprises an import/export element for loading and unloading cartridges into the apparatus. A cartridge store or library with slots therein stores the cartridges. The topmost slot initially receives the cartridges from the import/export element. A flipper mechanism is adapted to receive one of the cartridges from either the cartridge store or an optical disk drive. The flipper mechanism is adapted to invert or flip the cartridge and locate the cartridge adjacent the front of either the cartridge store or the optical disk drive. A picker mechanism moves the cartridge into and out of the flipper mechanism from either the cartridge store or the optical disk drive. Locating mechanisms are also provided for moving or locating the flipper and picker mechanisms.Type: GrantFiled: October 24, 1990Date of Patent: June 16, 1992Assignee: International Data Engineering, Inc.Inventors: Timothy P.

Patent number: 5056073Abstract: An optical disk cartridge handling apparatus for storing, handling, reading and writing of optical disks contained in cartridges which store data for a host computer. The apparatus comprises an import/export element for loading and unloading cartridges into the apparatus. A cartridge store or library with vertical slots therein stores the cartridges. The leftmost slot initially receives the cartridges from the import/export element. A flipper mechanism is adapted to receive one of the cartridges from either the cartridge store or one of preferably two optical disk drives suitably mounted below the cartridge store. A picker mechanism is mounted on the flipper mechanaism and moves the cartridge into and out of the flipper mechanism. The flipper mechanism is adapted to invert or flip the cartridge.Type: GrantFiled: November 9, 1990Date of Patent: October 8, 1991Assignee: 501 International Data Engineering, Inc.Inventors: Timothy P.
