Publication number: 20240009374Abstract: A connector for a NPWT system includes a first section and a second section. The first section has a first reduced pressure lumen and a first secondary pressure lumen for delivering reduced pressure from a pump unit to a primary wound site through the reduced pressure lumen and secondary pressure from the pump unit to the primary wound site through the first secondary pressure lumen. The second section has a second reduced pressure lumen and a vent lumen with the second reduced pressure lumen being in fluid communication with the first reduced pressure lumen of the first section for delivering reduced pressure from the pump unit to a secondary wound site through the second reduced pressure lumen and the vent lumen being in fluid communication with the atmosphere for delivering secondary pressure from the atmosphere to the secondary wound site through the vent lumen.Type: ApplicationFiled: July 10, 2023Publication date: January 11, 2024Applicant: DeRoyal Industries, Inc.Inventors: Dhanvin S. Desai, Vincent D. Jardret, Gavin L. Warrington

Publication number: 20190201595Abstract: A system for managing reduced pressure to a wound site includes a wound enclosure configured to form a substantially sealed volume around the wound site, a first closed volume, a second closed volume, and a controller. The first closed volume includes a primary pressure source and a canister fluidly coupled to the primary pressure source. The first closed volume is configured to apply reduced pressure to the wound site and deliver exudate collected from the wound site to the canister through a first lumen. The second closed volume includes a secondary pressure source and is configured to apply a secondary pressure to the wound site through a second lumen to facilitate flow of the exudate from the wound site to the canister through the first lumen. The controller is configured to communicate with at least the second closed volume for selectively applying the secondary pressure to the wound site.Type: ApplicationFiled: December 28, 2018Publication date: July 4, 2019Applicant: DeRoyal Industries, Inc.Inventors: Vincent D. Jardret, Dhanvin S. Desai, Jonathan M. Cayce, Joe L. Smith

Patent number: 8973257Abstract: Methods for building a neutron detector are disclosed, in which the neutron detector comprises at least two conductive cathode sheets lying parallel to one another and coated with neutron reactive material on at least one side thereof; dielectric material separating the cathode sheets and covering less than about 80% of their surface area; and a plurality of anode wires lying generally parallel to the cathode sheets and separated from them by the dielectric, with the distance between adjacent anode wires being no more than twenty times the distance between said cathode sheets. The cathode sheets may be flat or curved; they may be separate plates or they may be successive folds or windings of a single folded or spiral-shaped metal sheet.Type: GrantFiled: September 15, 2011Date of Patent: March 10, 2015Assignee: Material Innovations, Inc.Inventors: Andrew C. Stephan, Vincent D. Jardret

Patent number: 7923698Abstract: A neutron detector comprises a gas-filled dielectric shell, preferably a glass balloon, having opposite electrodes. An electric field is established whereby ionizing particles may be detected via ionization and current flow in the gas, using a pulse height analyzer or other conventional means. The dielectric shell preferably has low gas permeability and a bulk resistivity in the range of 108 to 1017 ?-m, and is preferably in the millimeter to centimeter size range. Multiple balloons may be arranged in parallel or may be individually addressable by the detector electronics.Type: GrantFiled: September 30, 2009Date of Patent: April 12, 2011Assignees: Material Innovations, Inc., UT-Battelle, LLCInventors: Andrew C. Stephan, Vincent D. Jardret, Roger A. Kisner

Patent number: 7919758Abstract: A neutron detector has a volume of neutron moderating material and a plurality of individual neutron sensing elements dispersed at selected locations throughout the moderator, and particularly arranged so that some of the detecting elements are closer to the surface of the moderator assembly and others are more deeply embedded. The arrangement captures some thermalized neutrons that might otherwise be scattered away from a single, centrally located detector element. Different geometrical arrangements may be used while preserving its fundamental characteristics. Different types of neutron sensing elements may be used, which may operate on any of a number of physical principles to perform the function of sensing a neutron, either by a capture or a scattering reaction, and converting that reaction to a detectable signal. High detection efficiency, an ability to acquire spectral information, and directional sensitivity may be obtained.Type: GrantFiled: September 30, 2009Date of Patent: April 5, 2011Assignee: Material Innovations, Inc.Inventors: Andrew C.
