Patent number: 8702129Abstract: A system for forming a fluid connection includes a first connector and a second connector. Both connectors include a tubular body having a membrane mounted on a distal end thereof. A support member facilitates the coupling of the connectors together so that the membranes are abutted together. Radiant energy is applied to the abutted membranes so as to first sterilize the membranes and then melt the membranes so that a passage is formed therethrough.Type: GrantFiled: April 23, 2008Date of Patent: April 22, 2014Assignee: HyClone Laboratories, Inc.Inventors: Arnold C. Bilstad, Bradley H. Buchanan, T. Michael Dennehey, Michael E. Goodwin, Jeremy K. Larsen, Whitt F. Woods, David V. Bacehowski

A rigid manifold, and in one instance a rigid frame is provided in the bag to keep passages open in use and to isolate one of the cells from the remaining cells. The dispenser employs an efficient and quiet air pressure operating system. In one application, a concentrated drink mix may be held in a reservoir and diluted within other cells in the bag for dispensing to a cup or the like. A valve system allows for the particulates in the liquid without compromising the function of the valve.Type: GrantFiled: August 14, 2003Date of Patent: March 7, 2006Assignee: Baxter International Inc.Inventors: Hal C.

Patent number: 5759147Abstract: A blood component separating device comprises a centrifuge bowl adapted for rotation about its axis in a centrifuge. The bowl defines an outer circumferential wall plus an inner circumferential wall, spaced from the outer wall, to define a circumferential slot adapted for receiving blood components. Access tubing is adapted for communication with the slot. Preferably, an elongated, flexible, collapsible inner liner is provided in the slot. Individual access tubing also may communicate with an elongated container interior between the ends of the elongated, collapsible container. Furthermore, a portion of the slot may define the shape of an outwardly extending spiral, to provide an increasing gravitational field upon fluids therein as the fluid moves along the slot.Type: GrantFiled: June 7, 1995Date of Patent: June 2, 1998Assignee: Baxter International Inc.Inventors: David V.

Patent number: 4937194Abstract: A system for metering nutrient media to cell culture containers includes a media flow conduit which defines at one end means for substantially aseptic communication with the source of the media. In a preferred embodiment, sterile connectors may be used for essentially sterile conditions. A branch conduit extends from the flow conduit at a location spaced from the ends. The branch conduit communicates with means for receiving a predetermined-volume aliquot of media through the media flow conduit from said one end. The flow conduit also defines a portion downstream from the branch conduit, which communicates with at least one cell culture container, each container being a flexible bag. At least part of the flexible bag is made of a material capable of providing at least 2 times the oxygen diffusion and at least 2 times the carbon dioxide diffusion between the bag interior and exterior, compared with an identically-sized, sealed bag having polyethylene walls 0.013 inch thick.Type: GrantFiled: January 30, 1989Date of Patent: June 26, 1990Assignee: Baxter International Inc.Inventors: Martha C.
