Abstract: Filtration systems and methods using a pump and pressure sensor are provided for improved efficiency in fluid filtration systems. A filtration system includes a pre-filter container joined to a post-filter container by a filter line having a filter. To reduce the time required for filtration a pump and pressure sensor are included in a filter inlet flow path. The pump also is used to provide air management in the system via pre-filtration evacuation of air from at least the filter.

Abstract: Porous filter media and methods for characterizing, selecting and using such media based on their dynamic wettability are disclosed. The dynamic wettability of a medium is a measure of how quickly a given liquid is absorbed by the medium.

Abstract: A simplified fluid separation method and device usable for various apheresis procedures, including plasmapheresis. At least one pump is utilized to draw a first fluid (e.g. whole blood) into a separation device. The separation device then operates to separate the fluid (e.g. whole blood) into first and second fluid fractions (e.g. a cell concentrate and blood plasma). The first and second fluid fractions are pumped from the separation device to separate first and second fluid fraction containers, both of which are positioned on a single weighing device, such as an electronic load cell. At least one of the fluid fractions is subsequently removed from its fluid fraction container and returned to the human subject or other fluid source. Weights recorded by the single weighing device are then utilized to calculate the actual weights of fluid and/or fluid fractions pumped by at least one pump during the procedure.

Abstract: A positive gauge blood pressure signal is transmitted to a gas column from a pulsatile blood flow stream hydrostatically higher than the pressure transducer. Particularly, a first conduit having a predetermined internal diameter smaller than a second conduit is connected at one end to the blood flow stream. The first conduit extends to a turnaround below the pressure transducer and is connected to the second conduit. The opposite end of the second conduit connects with the pressure transducer. The small internal diameter of the first conduit maintains the meniscus of the blood intact notwithstanding the pulsatile blood stream.
