Publication number: 20220331202Abstract: The present disclosure relates to arrangements for attaching an RFID tag to a liquid container, and particularly to a blood components container. The RFID tag may be inserted in an enclosure, such as peel tab, or in a sealed cup attached to a container port. The tag could alternately be embedded in a molded plug or component attached to a port. The RFID antenna could be painted or stamped on the surface of the container. Or the tag could be inserted into the container to float freely in the liquid components. The RFID source may be secured around the neck of a rigid or semi-rigid container, attached with a tether or attached to a connector assembled in association with a blood component or other fluid flow path.Type: ApplicationFiled: April 12, 2022Publication date: October 20, 2022Inventors: Christine Larson, Bryan Blickhan, Carlos Calderon, Daniel Lynn, Senan Ozbag, W. Timothy Watts, Daryl R. Calhoun

Patent number: 11097037Abstract: Systems and methods are provided for separating a red blood cell-containing fluid into separated red blood cells and another fluid constituent. A suitable system includes a disposable fluid flow circuit and a durable, reusable separation system, with the circuit being mounted onto or otherwise associated with the separation system. The circuit includes a membrane separator for separating the fluid into its constituent parts, as well as a leukoreduction filter. The leukoreduction filter may be used before or after the red blood cell-containing fluid has been passed into the membrane separator. The red blood cell-containing fluid (if the leukoreduction filter is positioned upstream of the membrane separator) or the separated red blood cells (if the leukoreduction filter is positioned downstream of the membrane separator) may also be passed through a microaggregate filter prior to passing through the leukoreduction filter.Type: GrantFiled: June 13, 2019Date of Patent: August 24, 2021Assignee: Fenwal, Inc.Inventors: Daniel R. Lynn, Daryl R. Calhoun

Publication number: 20180303997Abstract: A membrane separation device is disclosed along with systems and methods employing the device in blood processing procedures. In one embodiment, a spinning membrane separator is provided in which at least two zones or regions are created in the gap between the membrane and the shell, such that mixing of the fluid between the two regions is inhibited by a radial rib associated with the membrane that decreases the gap between the membrane and the shell to define two fluid regions, the ridge isolating the fluid in the two regions to minimize mixing between the two. Automated systems and methods are disclosed for separating a unit of previously collected whole blood into components, such as concentrated red cells and plasma, for collecting red cells and plasma directly from a donor in a single pass, and for cell washing. Data management systems and methods and priming methods are also disclosed.Type: ApplicationFiled: July 2, 2018Publication date: October 25, 2018Inventors: Benjamin E. Kusters, Christopher J.

Patent number: 6688476Abstract: A fluid filter assembly for filtering fluids such as blood is described. The assembly includes first and second filter housing elements formed by an injection molding process. Each element is flexible and includes a peripheral flange formed thereabout and a fluid communicating port formed therein. Filter media, such as a filter membrane, is sealed between the mating flanges of two elements. The fluid filter assembly is capable of collapsing and expanding during the filtration process depending upon the composition of the fluid passed there through. A method for making the filter assembly and systems for using the filter assembly are also disclosed.Type: GrantFiled: February 27, 2002Date of Patent: February 10, 2004Assignee: Baxter International Inc.Inventors: Julian P Breillatt, Jr., John C Burnham, Allen R Wons, Randy Murphy, Daryl R Calhoun, Daniel R Lynn

Publication number: 20030209479Abstract: A blood collection system has a container for holding blood and a filter communicating with the container, mutually arranged for handling as a unit. The filter (20) contains a fibrous filter medium (28) housed within two flexible sheets (32, 34) of plastic. A first seal (36) joins the sheets (32, 34) directly to the filter medium (28) inboard of the peripheral edge (40) of the filter medium (28), and a second seal (38) joins the sheets (32, 34) outboard of the peripheral edge (40) of the filter medium (28). A region (42) of the filter medium (28) extends between the first and second seals (36, 38) to cushion contact with the filter housing during handling.Type: ApplicationFiled: March 10, 2003Publication date: November 13, 2003Inventors: Daniel R Lynn, Allen R Wons, Luc Mespreuve, Daniel Vandendaul, Gregory Soudant, Tat C Mui, Daniel M Karlovsky, Randy Murphey, Daryl R Calhoun, Shin-Ichiroh Oka, Michihiro Tsuji
