Patent number: 8590555Abstract: The present invention presents various novel approaches to solving the problems inherent in measuring biological pressures in high pressure systems. Thus, to protect a pressure transducer exposed to fluid flows at higher pressures than its overpressure rating, a novel valve is used that closes a protected leg in which the transducer is located. The various exemplary embodiments of such valves each have a high pressure input, one or more low pressure inputs, and an output. In operation, when a high pressure fluid flow occurs at a high pressure input, such valves automatically close the low pressure inputs. Alternatively, a novel transducer system is presented, which automatically limits the effective pressure sensed by a transducer to a certain maximum.Type: GrantFiled: January 26, 2011Date of Patent: November 26, 2013Assignee: ACIST Medical Systems, Inc.Inventors: Robert F. Wilson, Douglas J. Duchon, Mark Gabbard, Khader Mohiuddin, Thomas J. McPeak

Patent number: 6450375Abstract: A slit closure valve for container openings includes a membrane member of flexible material having an at least unidirectionally aligned slit-like outlet opening and a base member peripherally surrounding the membrane member and connected to the membrane member. The outlet opening is held in its closed position by the resilient properties of the material although it is adapted to be moved into its open position against the resilient bias force of the material by a predetermined differential positive pressure exerted on one side of the membrane member. A peripheral wall portion of the base member and an adjacent wall portion of the membrane member include therebetween an acute angle of less than 90′.Type: GrantFiled: July 17, 2001Date of Patent: September 17, 2002Assignee: Georg Menshen GmbH & Co. KGInventors: Johannes Hins, Timothy I. Gabbard, Mark Gabbard
