Patent number: 6764482Abstract: A dual-filled twin bag, a packaging including the twin bag, and a method for forming the packaged twin bags are provided. Each of two bags, a solution bag (10) and a drain bag (12) for a system used for a peritoneal dialysis procedure, are filled, at least partially, with a solution (14). A tubing set (16) connects the two filled bags (10,12) and may also be filled with solution (14) which is added to the bags (10,12) and the tubing set (16) during the manufacturing process. Alternatively, the tubing set (16) may be filled with air. The tubing set (16) is sandwiched between the solution bag (10) and the drain bag (12) and subsequently packaged in an overpouch (24). The method for forming the package including the bags filled with solution is simplified and the overall package size is reduced due to the sandwiched tubing set (16) between the solution bags (10,12) and the provision of solution in both bags (10,12).Type: GrantFiled: October 29, 2002Date of Patent: July 20, 2004Assignee: Baxter International Inc.Inventors: Michael R. Keilman, Walter A. Makaryk, Joseph A. Giertych

Patent number: 4968624Abstract: The present invention provides a large volume flexible container capable of containing a fluid to be maintained under sterile conditions. The container comprises an inner liner constructed from a polyolefin that defines an interior of the container and an outer liner constructed from a three-layer laminate. The laminate includes an inner layer constructed from a polyolefin that will, upon the application of sufficient energy, bond to the polyolefin of the inner liner, a middle layer constructed from a barrier material, and an outer layer; the inner liner and outer liner being sealed together along edges of the container. At least one tube member, for accessing the container, extends from a face of the container, and includes an end that is secured to the container, a length of flexible tubing for defining a channel through which fluid can flow, and a connector at a second end. A structure for housing the container is also provided.Type: GrantFiled: April 25, 1989Date of Patent: November 6, 1990Assignee: Baxter International Inc.Inventors: David Bacehowski, Arnold Bilstad, Michael R. Keilman

Patent number: 4910147Abstract: A cell culture media container is provided. The container comprises a body constructed from flexible film and defining a containment area for containing the cell culture media, the body including a front face and a back face, the front and back face being sealed to each other along at least three sides thereof. The container includes a fill port for filling the containment area with cell culture media, the port being sealed to a face of the body and being so constructed and arranged that it extends from the face normal thereto. The container is constructed from a high barrier, optically clear, radiation sterilizable film.Type: GrantFiled: September 21, 1988Date of Patent: March 20, 1990Assignee: Baxter International Inc.Inventors: David V.

Patent number: 4717668Abstract: A plastic roller bottle is provided for suspension cultures for bacteriology or other cell growth or maintenance. The roller bottle comprises a closed bottle defining a longitudinal axis and having flexible plastic walls. Aseptically sealable means for access into the closed body are provided as well. A plurality of spaced reinforcement rings are defined in the flexible plastic walls about the longitudinal axis, to cause the body to normally retain a predetermined, generally cylindrical shape. The flexible plastic walls, apart from the rings, are made of a plastic formulation, and are of a thickness such that the oxygen and carbon dioxide diffusion which takes place through said walls is sufficient to support desired biochemical culturing processes taking place within the roller bottle without venting.Type: GrantFiled: December 12, 1986Date of Patent: January 5, 1988Assignee: Baxter Travenol Laboratories, Inc.Inventors: Michael R. Keilman, Ronald P. Symbol

Patent number: 4568345Abstract: A container for pooling plasma and the like has an integral cap. The cap includes an air vent with an inline bacterial filter. The cap also includes a fluid passage to which a length of tubing is integrally connected. The tubing includes at its unattached end one or more connector members which can be coupled to a fluid source to enable fluid to be transferred into the container via the tubing. The connector members are releasably secured to the cap prior to use. After fluid transfer is complete, the transfer tubing is sealed and severed close to the cap. The cap includes a pocket which receives the remaining sealed end portion of the tubing to protect the sealed end portion from inadvertent contact and damage during subsequent handling. The cover includes a plug which can be moved into a position which hermetically seals the vent and, thus, the entire container.Type: GrantFiled: September 21, 1983Date of Patent: February 4, 1986Assignee: Baxter Travenol Laboratories, Inc.Inventors: Michael R. Keilman, Richard L. West
