An oxygenator module for gas exchange between blood and a gas in an extracorporeal lung support system, with several layers of semipermeable, gas-perfusable hollow fibers, wherein the hollow fibers of one of the layers are oriented at an angle of rotation about a central longitudinal axis of the oxygenator module with respect to the hollow fibers of another one of the layers, and with a potting which extends along the central longitudinal axis and in which the hollow fibers are fixed, wherein the potting defines a cavity that extends along the central longitudinal axis and in which the hollow fibers are arranged and which is blood-perfusable in the direction of the central longitudinal axis, wherein the potting has an essentially circular inner sheath surface that limits the cavity radially outward; as well as a method for producing the oxygenator module.

Disclosed are an extendable pressurized-type hollow fiber membrane module which facilitates improvement of filtrate quality through a multistep-filtration, enhanced easiness of installation and maintenance, decrease of footprint, and/or enlargement of filtration apparatus (without causing decrease of permeate flux of a unit hollow fiber membrane), and a filtration apparatus manufactured using the same. The filtration apparatus of the present invention comprises first and second pressurized-type hollow fiber membrane modules, wherein an inlet port of the first pressurized-type hollow fiber membrane module for introducing feed water and an outlet port of the second pressurized-type hollow fiber membrane module for discharging filtrate or air are coupled to each other.

The present application discloses novel systems for conducting the filtration of blood using manifolds. The manifolds integrate various sensors and have fluid pathways formed therein to direct fluids from various sources through the requisite blood filtration or ultrafiltration system steps.

An apparatus for water purification comprising a flexible, collapsible water container (2a, 2b) to which a purification unit (4) is connected by a tube (3) for purification of water driven through the purification unit (4) by gravity.
