Patent number: 8882708Abstract: 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: GrantFiled: October 30, 2008Date of Patent: November 11, 2014Assignee: ACIST Medical Systems, Inc.Inventors: Marty Hieb, Khoi Le, Bill West, Darryl Wrolson, 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.

Publication number: 20120013116Abstract: A method of advertising and applying brand identification to toiletry products. The disclosed method includes providing a brand name, a specific product name or further details regarding the product or the company on the product itself. As the product is dispensed or consumed, the user is made aware of the brand or product name, providing a means for brand association with a targeted audience and allowing a consumer to identify a given product after use and initial impression. The logo of the brand or product may be watermarked, embossed or raised on the product. The product may be any consumable household product, including toiletries such as toilet paper and tissues, kitchen products such as paper towels and dust rags, or other household products that would benefit from product identification for the purposes of developing brand loyalty.Type: ApplicationFiled: June 17, 2011Publication date: January 19, 2012Inventor: Bill West

Patent number: 5249952Abstract: A three-chambered combustion burner is provided with a seed fuel under pressure to burn simultaneously injected waste products such as incompletely combusted exhaust fumes or air entrained combustible solid waste. An explosive mixture is provided in a first chamber and ignited. The heated and pressurized gas products are ejected into a second smaller combustion chamber into which air is injected. The hot and incompletely combusted products in the second chamber explosively reignite and are ejected into a yet smaller third combustion chamber. Air is again injected into the third combustion chamber wherein the products again explosively reignite to be ejected through a jet nozzle. The heat energy output of the burner or its propulsive momentum thrust may be utilized as appropriate in other applications. The toxicity of the gaseous or solid waste products burnt in the chambers is reduced and oxidized by the injection of air and hydrolization of water also injected with the waste products.Type: GrantFiled: April 24, 1992Date of Patent: October 5, 1993Assignee: Cosmos Ventures, Inc.Inventors: Bill West, Thomas Trulis
