    Abstract: A method correlates average fiber diameter with performance for a complex filtration media comprising a matrix of fibers having a fibrillated component with a diameter so small (e.g., less than 0.01 microns), that cannot be physically measured with accuracy. The method manufactures a selected matrix, derives the number average diameter of the fibers according to prescribed steps, some of which do not require actual physical measurements, and observes a performance characteristic. The method repeats the foregoing steps for different matrixes, yielding different number average diameters. The method expresses change in the selected performance characteristic as a function of change in number average diameter of the matrices.

    Abstract: A device for indicating priming of an infusion line includes: a microporous membrane that blocks transmission of light therethrough when dry and that allows transmission of light therethrough when wet; a source of a light signal covered by the microporous membrane, light from the source of the light signal being transmitted through the microporous membrane upon the microporous membrane becoming wet; and a sensor 354 that senses light from the source of the light signal, the sensor 354 being separated from the source of the light signal by at least the microporous membrane, and in electrical communication with a controller 350 in communication with an alarm 352 which is activated by the controller 350 upon detection by the sensor of light from the source of the light signal. -r > 'N> 'z. n \ > C' V ,~,, N~ t~ * "N"> \N N

    Abstract: A priming indicator for a fluid infusion system includes a luer cap (20) or other component of the infusion system having an indicator surface (22) covered by a membrane (24). The membrane exhibits a first visual characteristic, such as being opaque, when dry and exhibits a second characteristic, such as becoming less opaque, when wet. Once the membrane becomes wet, indicia on the surface, which may be provided on a rod at least partially covered by the membrane, becomes visible, thereby indicating an intravenous tube to which the luer cap is secured has been primed or is nearly primed. The indicator may alternately be employed at an upstream end of an infusion set, such as at the port of a medical bag providing a supply of fluid, to indicate a low level of fluid in the medical bag.

    Abstract: Un indicador de imprimación para un sistema de infusión de fluido incluye una tapa (20) de tipo luer u otros componente del sistema de infusión teniendo una superficie indicadora (22) cubierta por una membrana (24). La membrana exhibe una primera característica visual, tal como siendo opaca, cuando se seca y exhibe una segunda característica, tal como volverse menos opaca, cuando se humedece. Una vez que la membrana se humedece, indicaciones en la superficie, las cuales pueden ser provistas en una barra al menos parcialmente cubierta por la membrana, se vuelven visibles, indicando así que un tubo intravenoso al cual la tapa de tipo luer está asegurada ha sido imprimado o casi imprimado. El indicador alternativamente puede ser empleado en un extremo corriente arriba de un equipo de infusión, tal como el puerto de una bolsa médica proporcionando un suministro de fluido, para indicar un bajo nivel de fluido en la bolsa médica.

    Abstract: A device and method for inactivating pathogens in therapeutic fluids with sterilizing radiation in a continuous flow arrangement while exhibiting radiation dose uniformity and narrow residence time distribution of the fluid within the device. The device (10) comprises a radiation permeable cylindrical tube (12) having a concentric cylindrical rotor (14) disposed therein, thereby providing a thin gap (16) therebetween. A top plate (18) having a fluid outlet (26) and a bottom plate (20) having a fluid inlet (24) seal the cylindrical tube (12). The inlet (24) and outlet (26) are both in fluid communication with the thin gap (16). A rotor shaft (36) is diposed axially through the cylindrical rotor (14) and is connected to a motor (30). A pump provides fluid flow through the device (10). A radiation source provides sterilizing radiation to the fluid through the cylindrical tube (12). As the fluid flows, the motor (30) drives the rotor (14) to impart Taylor vortices to the fluid flow, which exchanges the fluid closer to the cylindrical tube (12) with the fluid closer to the rotor (14).
