摘要： A cell retention device includes a structured support with a plurality of circumferentially distributed ribs to retain the active filtering surface of a flexible, porous membrane filter medium. The filter medium surrounds the support in contact with the peaks of the ribs, thereby forming axial voids between the rib peaks. This arrangement imparts sufficient structural support over small regions of the filter medium to facilitate its use in a circular (or other rounded) configuration while providing sufficient channel volume to support high throughput of fluid sparse of cells.

摘要： A gas separation system for extraction of gas from pressurized fluid has a gas sampling interface and gas circulation tubing to pass sampled gas to a gas sensor to determine the character or a property of the gas. The gas sampling interface includes a semi-permeable membrane in the form of tubing having an inner core volume with an internal support that provides multiple supporting surfaces to prevent collapse of the tubing wall against external pressure and provides interstitial spaces for the flow of gas. Internal supports may include a coil of spring-like configuration fitted coaxially within the tubing; or multiple filaments that form a longitudinal bundle within the core of the tubing, or both. An outer tubular conduit surrounding the semi-permeable membrane tubing provides a flow path for the external fluid to increase the rate of diffusion of dissolved gases through the semi-permeable membrane.
