Patent number: 10814047Abstract: Fluid collection systems and methods are disclosed which may utilize suction to draw fluids into containers for storage and eventual disposal. The system may utilize rigid or semi-rigid canisters to provide a chamber in which fluids may be collected under negative pressure, stored, and transported. The system may utilize disposable or reusable flexible, semi-rigid, or rigid liners for isolating fluid and liquid waste from the walls of the canister. In various embodiments, either a single canister assembly or multiple canister assemblies are mounted to a manifold, the manifold being configured to support each canister assembly and/or provide a connection to a source of suction for each canister assembly.Type: GrantFiled: April 25, 2017Date of Patent: October 27, 2020Assignee: ALLEGIANCE CORPORATIONInventors: Raymond Reade Harpham, Brent Lee Burchfield, Kok Hern Law, Rajesh Gladwin Dharmadas, Wei Chen Lie, Robert John Weinberg, Stephany Chang, Stacey Hoebel Burgardt, Matthew Michael Bruggeman, David James Stroud, Talya Mathein

Patent number: 10568771Abstract: A wound dressing system that includes a conformal cover and an infusion pump is provided. The cover includes a fluid port and an oxygen catalyst. The infusion pump is configured to deliver a bioactive liquid to the cover via the fluid port. The liquid includes an oxygen precursor. Upon combination, the oxygen catalyst and precursor react to form oxygen. A method of applying a wound dressing system including a bioactive powder, a bioactive liquid, and a conformal cover to a wound site is also provided. The method includes applying the powder to the wound site; securing the cover around the wound site, where the cover includes an oxygen catalyst and a fluid port; and delivering the bioactive liquid to at least an inner layer of the cover via the fluid port, where the bioactive liquid includes an oxygen precursor.Type: GrantFiled: January 23, 2015Date of Patent: February 25, 2020Assignee: Avent, Inc.Inventors: John Gavin MacDonald, Ramanathan S. Lalgudi, Karien J. Rodriguez, Reade Harpham, Stephanie Kute, Alison Salyer Bagwell, Brian Joseph Cuevas

Publication number: 20130274599Abstract: A sensor device for detecting a change in fluid level within body tissue comprising a housing with bridge segments connecting at intersections arranged to circumscribe an opening. Further, antenna elements are partially seated within the housing at intersections of bridge segments, comprise a generally planar antenna mounted to a substrate material at a base of the planar antenna, and an electrical shield surrounding the substrate. Also, an outer surface of the planar antenna faces away from the substrate. The antenna elements comprise at least first and second antenna element pairs having transmitting and receiving antenna elements and a bridging segment. A high sensitivity zone is formed between the transmitting antenna and receiving antenna. The antenna element pairs are spaced to create an area of reduced sensitivity between the high sensitivity zones, and the space is set so that the sensor is insensitive to fluid changes of a predetermined volume.Type: ApplicationFiled: September 14, 2012Publication date: October 17, 2013Inventors: Chad E. BOUTON, Felicia R. RUGGERI, R. Reade HARPHAM, Jeffrey R. HELD

Publication number: 20130071944Abstract: An article of manufacture embodiment comprises a sample cartridge including a sample substrate, and an enclosure including a sample ingress port. The enclosure mates with the sample cartridge to define a sample container containing the sample substrate which is accessible in the sample container via the sample ingress port. The sample cartridge including the sample substrate is removable from the sample container. A sampling method embodiment comprises disposing a sample on a sample substrate in a sample container and removing a sample cartridge including the sample substrate from the sample container. An article of manufacture embodiment comprises a sample substrate, a sample container containing the sample substrate and including a sample ingress port providing access to the sample substrate in the sample container, and a sample cartridge including the sample substrate. The sample cartridge including the sample substrate is removable as a unit from the sample container.Type: ApplicationFiled: October 4, 2010Publication date: March 21, 2013Applicant: BATTELLE MEMORIAL INSTITUTEInventors: M.
