HIGHLY RETENTIVE POLYAMIDE HOLLOW FIBER MEMBRANES PRODUCED VIA CONTROLLED SHRINKAGE
Described herein is a polyamide hollow fiber membrane and methods of making and using the hollow fiber membrane. The polyamide hollow fiber membrane has an isopropanol permeability of from about 5 L/m2 h bar to about 150 L/m2 h bar and a particle rejection percentage of about 100% for particles having a nominal diameter of from about 1 nm to about 25 nm. The polyamide hollow fiber membranes described herein are particularly useful for photoresist filtration, for example.
Blood processing cartridges and systems, and methods for extracorporeal blood therapies
In embodiments of the invention, there is provided a dialyzer or filter comprising hollow fibers, in which blood flows on the exterior of the hollow fibers, and dialysate or filtrate may flow on the inside. The external surfaces of the hollow fibers may have properties of smoothness and hemocompatibility. The fiber bundle may have appropriate packing fraction and may have wavy fibers. Optimum shear rates and blood velocities are identified. Geometric features of the cartridge, such as pertaining to flow distribution of the blood, may be different for different ends of the cartridge. Air bleed and emboli traps may be provided. Lengthened service life may be achieved by combinations of these features, which may permit additional therapies and applications or better economics.
A DEVICE FOR ASEPTICALLY TREATING A SUSPENSION
There is provided a device comprising at least the followings: a hollow fiber type separator for separating a liquid A from a suspension comprising an inlet and outlet for passing the suspension, which communicate with the inside of hollow fibers, and at least one discharge port for discharging the separated liquid A, which communicates with the outside of the hollow fibers; an aseptic connection connector for aseptically connecting a bag containing the suspension in a non-aseptic environment, which is connected to the inlet of the hollow fiber type separator; a drainage bag for storing the separated liquid A, which is connected to the discharge port of the hollow fiber type separator; and a collection bag for storing a suspensoid from which the liquid A has been separated, which is connected to the inlet or outlet of the hollow fiber type separator.
CARTRIDGE FOR WATER PURIFIER, AND WATER PURIFIER
A cartridge for a water purifier has: a granular filter medium; an inner cylinder that supports the granular filter medium from inside, and does not allow the granular filter medium to pass through but allows water to pass through; an outer cylinder that supports the granular filter medium from outside, and does not allow the granular filter medium to pass through but allows water to pass through; a cap member that connects one end of the inner cylinder to one end of the outer cylinder, and that has an opening connected with an inner diameter side channel; an inner cylinder blocking member that blocks the other end of the inner cylinder; and an end portion adhesion material for adhering and fixing the inner cylinder blocking member and the outer cylinder, wherein the inner cylinder blocking member, the outer cylinder, and the end portion adhesion material are arranged so as to integrally block the granular filter medium.
Method of Filtering Water
A method of operating a filtration unit of a filtration system includes feeding, during filtration, feed water containing suspended particulate material to an inside of each of a plurality of hollow fibres through a first inlet and a second inlet of each hollow fibre while simultaneously removing a filtrate from an outside of each of the hollow fibres through an outlet of a filtration elements. In addition, the method includes feeding, during back-washing, back-wash water to the outside of the hollow fibres through the outlet of the filtration element. Further the method includes discharging, in a first back-wash cycle, back-wash water containing entrained particulate material from the inside of the hollow fibres from one end thereof. Still further, the method includes discharging, in a second back-wash cycle, back-wash water containing entrained particulate material from the inside of the hollow fibres from the other end thereof.
Device for exchanging substances between blood and at least one gas/gas mixture
A device for mass transfer between blood and at least one gas/gas mixture, includes first and second chambers through which blood is able to flow and in each of which a respective plurality of mass-permeable hollow fibers are disposed around a respective axially extending core element, wherein a gas/gas mixture is able to flow through, and blood is able to flow around, the hollow fibers, wherein the second chamber follows the first chamber in the blood flow direction, wherein the first and second chambers are disposed next to one another, and in particular disposed spaced apart between the core element center axes thereof, and the two chambers have a connection in an axial end region by which the chamber volumes through which blood is able to flow are connected, and in particular are connected in the direction of the spacing.
Device for cross flow filtration
A whole blood filtration device is provided with a filter membrane separating a feeding volume and a clean side of the filter membrane from each other. The feeding volume communicates with a first feeding side opening and with a second feeding side opening. The filter membrane has pores with a pore size that ensures permeability of the filter membrane to blood plasma/serum and that retains blood cells. The first feeding side opening can be coupled to a first blood pump for feeding blood from the first feeding side opening into the feeding volume so that blood plasma/serum permeates the filter membrane and blood cells, retained by the filter membrane, exit from the feeding volume through the second feeding side opening.
Device for whole blood cross flow filtration using a cannula needle
A whole blood filtration device is provided with a filter membrane separating a feeding volume and a clean side of the filter membrane from each other. The feeding volume communicates with a first feeding side opening and with a second feeding side opening. The filter membrane has pores with a pore size that ensures permeability of the filter membrane to blood plasma/serum and that retains blood cells. The first feeding side opening can be coupled to a first blood pump for feeding blood from the first feeding side opening into the feeding volume so that blood plasma/serum permeates the filter membrane and blood cells, retained by the filter membrane, exit from the feeding volume through the second feeding side opening.
