  • Patent number: 8702129
    Abstract: 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.

  • Patent number: 7237691
    Abstract: A flexible bag having expansible and collapsible cells can be used in a liquid dispenser. 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 manifold is capable of altering the volume of one of the cells so that the same bag can be used in different applications.

  • Patent number: 7007824
    Abstract: A liquid dispenser uses a flexible bag having expansible and collapsible cells. 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.

  • Patent number: 6162206
    Abstract: A resealable access site (10) is provided for allowing a cannula (18) multiple accesses to an internal cavity (35) defined by a container (12). The access site (10) includes a first conduit (28) defining a passageway (29) forming a fluid path to the cavity within the container. Sealingly attached to the conduit (28) is a housing (26) with a lower portion (26a) and a lower flange (68) attached to a lower end of the lower portion and extending radially inward from the lower portion. A septum (24) is disposed and compressed within the lower portion, with the septum defining an opening (46) extending upward through at least a portion of the septum. The opening (46) is sized for insertion of the cannula (18) through the septum (24) with the septum sealing about the exterior of the cannula. The septum (24) is maintained in the housing by the support provided by the opposing flange (68) and conduit (28).

  • Patent number: 5759147
    Abstract: 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.

  • Patent number: 4939151
    Abstract: An adherent cell culture flask is provided. The flask includes a body constructed from a first side wall and a second side wall, each side wall having an interior surface and an exterior surface. The first and second side walls are sealed together to define a chamber. The first side wall is constructed from flexible film and includes on its interior surface a charged surface for facilitating the attachment of cells thereto. The second side wall is constructed from flexible film and includes a non-smooth interior surface for preventing the first side wall interior surface from sticking to the second side wall interior surface.

  • Patent number: 4937194
    Abstract: 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.
