  • Patent number: 10894982
    Abstract: A method of preparing reagents includes inserting a cartridge into an instrument. The cartridge includes a plurality of reagent enclosures disposed in a cavity of the cartridge and exposing a port to an exterior of the cartridge. Each reagent enclosure includes a reagent container including a reagent and an internal cavity defining a compressible volume, an opening defined through the reagent container to the internal cavity. The method further includes connecting a plurality of fluid ports to the openings of the plurality of reagent enclosures; applying a solution through the fluid ports to at least partially fill the plurality of reagent enclosures; and cycling a pressure of the cavity, whereby for each of the reagent enclosures, during increasing pressure, the solution enters the internal cavity of the reagent container, combines with the reagent, and compresses the compressible volume, and during decreasing pressure, the compressible volume decreases and the reagent is ejected through the opening.

    Abstract: A microfluidic device for controlled encapsulation of particles of sub-millimetric dimensions, or clusters of such particles, the device comprising: a first duct for delivering a first liquid phase containing particles for encapsulating in suspension; a second duct for conveying a flow of a second liquid phase that is immiscible with said first liquid phase; the first duct opening out into the second duct and forming a fluidic junction therewith; at least one microfluidic duct for discharging the first liquid phase flowing in said first duct and provided with a mouth located upstream from said junction and liable to be obstructed, at least in part, by a particle in suspension, thereby causing pressure to rise in the first duct. The invention also provides a microfluidic system including such a device, and a method of encapsulation based on using such a device.

  • Patent number: 8999046
    Abstract: A cell expansion system includes an air removal chamber to provide a bubble trap so that air and/or gas bubbles do not enter the bioreactor of the cell expansion system. The air removal chamber includes a pair of ports situated at the bottom of the air removal chamber. An entrance port allows fluid to enter the air removal chamber, and an exit port allows fluid to exit the air removal chamber. In one embodiment the air removal chamber forms an element of a premounted fluid conveyance assembly for use with a cell expansion machine.

  • Publication number: 20150079663
    Abstract: A dispensing unit that sucks and discharges a blood specimen via a nozzle. A liquid level-measuring unit that measures the liquid level height. A serum volume-estimating unit that estimates the volume of the serum separated in the blood specimen, on the basis of the total blood volume, said total blood volume corresponding to the volume of the blood specimen and having been derived from the liquid level height, and a hematocrit value. A residual volume-estimating unit that calculates the volume of the serum remaining after suction, on the basis of the serum volume estimated by the serum volume-estimating unit and the volume of the serum that is going to be sucked by the dispensing unit. A controller that controls the suction procedure of the dispensing unit so that the estimated residual volume is not less than the desired volume of the serum to be left in the blood collection tube.

  • Publication number: 20150079664
    Abstract: Embodiments described herein generally relate to methods and systems for using an air removal chamber as a control for a process in a cell expansion system. The air removal chamber may be mounted on a fluid conveyance assembly for use with the system. Fluid is pumped into a fluid containment chamber of the air removal chamber, in which the level of fluid in the fluid containment chamber may be monitored through the use of one or more sensors. The sensors are capable of detecting air, a lack of fluid, fluid, and/or a gas/fluid interface, e.g., an air/fluid interface, at measuring positions within the air removal chamber. Protocols for use with the system may include one or more stop conditions. In an embodiment, the stopping of a process is automated based on the detection of air, a lack of fluid, and/or a gas/fluid interface in the air removal chamber.

  • Patent number: 8980177
    Abstract: Disclosed is a fluidic assay device for assaying at least one property of a liquid sample, the device comprising: (i) a liquid sample application region; (ii) at least one test flow path in liquid flow communication with the sample application region; (iii) a reference flow path in liquid flow communication with the sample application region; and (iv) a junction region, at which the test flow path and the reference flow path contact one another, the junction region typically comprising an outlet, conduit, chamber or other portion which permits the onward flow of liquid; wherein a liquid flowing along the reference flow path, upon reaching the junction region, has the effect of preventing the flow of liquid along the test flow path. The invention relates to a fluidic device for the passage of a liquid. It also relates to an assay device suitable for measurement of the amount and/or presence of an analyte in, or property of, a fluid sample.

  • Publication number: 20150072401
    Abstract: In a closed system culture vessel to be used in an automated culture apparatus, some of the ports perform both liquid supply and gas supply functions. Culture medium is thereby made to flow always in one direction. The culture vessel is also configured so that, in the complete culture medium exchange process and the effluent recovery process for analyzing culture medium components, waste liquid medium does not get mixed into fresh culture medium.
