Publication number: 20070151626Abstract: A bypass for a tube set for directing the flow of a fluid component includes an inlet passage for fluid connection with a source of said fluid component, an outlet passage for fluid connection with a first bag compartment, and a bypass passage for fluid connection with a second bag compartment. A flow control device in the bypass passage is operable in a first position in which the flow control device seals the bypass passage, and a second position in which the flow control device unseals the bypass passage to receive a tubing line connected with said second bag compartment.Type: ApplicationFiled: March 2, 2007Publication date: July 5, 2007Inventor: Joel Bartholomew

Patent number: 7204277Abstract: A tube set for dispensing components into a product bag includes a plurality of tubing lines, a manifold, and a bypass. The manifold has a plurality of inlets, each inlet adapted for connection to a respective tubing line. The manifold also has an outlet connectable to a first feed tube of a product bag. The bypass is associated with at least one of the plurality of tubing lines. The bypass has a bypass inlet connectable to the tubing line associated with the bypass and at least two outlets. A first outlet is connected to a tube line in fluid communication with an inlet of the manifold and the second outlet is removably connectable to a second feed tube in fluid communication with the product bag, independent of the manifold.Type: GrantFiled: September 16, 2004Date of Patent: April 17, 2007Assignee: B.

Publication number: 20070038189Abstract: Needleless access port valves are generally discussed herein with particular discussions on needleless access port valves incorporating a moving cannula. The moving cannula may be part of a valve core having a diaphragm, a septum, and a plurality of biasing members. A plurality of openings disposed on the hollow cannula permit fluid flow between the inlet and the outlet of the valve housing. The inlet and the outlet may be placed in fluid communication by inserting a medical implement in the inlet and moving the valve core.Type: ApplicationFiled: July 22, 2005Publication date: February 15, 2007Inventor: Joel Bartholomew

Patent number: 5583052Abstract: A formulation preparation device is provided herein which contains a valve assembly, transfer spikes, syringe port and tube, these components being interconnected so as to provide for controlled fluid flow between the spikes and port, through the assembly, in specific directions only. The device has an enclosed, sterilizable, gripable housing and can be used to mix combine fluids in reproducible and predetermined proportions. Combination is accomplished aseptically, avoiding contact between the device's operator and the fluids and the substances combined. Biologically active compounds can be combined with one or more fluids, including such aqueous liposome suspensions, using the device. A formulation preparation kit containing, in addition to the device, the fluids and compounds to be formulated is thus also provided herein; methods of using the device to prepare such formulations are further provided herein.Type: GrantFiled: May 23, 1995Date of Patent: December 10, 1996Assignees: The Liposome Company, Inc., B.

Patent number: 5437655Abstract: A burette top vent which resists air blockage includes a peripherally skirted cap having a generally planar circular base transfixed by a short integral tube having an upper portion to which tubing from a source of fluid may be attached and a lower portion from which fluid can drip into the burette. The base is perforated by an array of arcuate slots that permit air to enter the burette, and the bottom surface of the base has a shallow annular relief intersecting the slots. A ring-shaped hydrophobic filter disk hermetically affixed beneath the relief. The relief prevents the filter disk from lying flush against the bottom surface of the base.Type: GrantFiled: September 3, 1993Date of Patent: August 1, 1995Assignee: B. Braun Medical Inc.Inventor: Joel Bartholomew
