The present disclosure relates to an apparatus used in the production of a sterilizing filter for dead-end filtration of medical liquids which comprises a plurality of microporous hollow fiber membranes having a large inner diameter, and to a process for operating the apparatus.

The present disclosure relates to a process and an apparatus for potting hollow fiber membranes in a diffusion and/or filtration device, e.g., an ultrafilter or a capillary dialyzer.

The present invention addresses to a high-pressure vessel for packaging hollow fiber type membranes with application in the field of separation process with contactors with membranes aiming at a compact device/piece of equipment configured for the packaging of hollow fiber type bundles that can be used for various fluid separation processes such as liquid-liquid, liquid-gas and gas-gas, capable of working at high-pressures, enabling adequate hydrodynamic conditions and easily scalable. It is called a module the general piece of equipment, consisting of the vessel (A or C), object of the present invention, and the membranes packed inside the vessel. This piece of equipment consists of a vessel inside which the membranes are placed (14), and two heads attached at the ends (B or D). Each head has two connection points, thus allowing this device to be used with membrane contactors-type separation systems, such as “classical” permeation systems (liquid-liquid, gas-gas, pervaporation).

A hollow fiber membrane module (100) of the present disclosure includes: a plurality of hollow fiber membranes (10); a binding portion (20) binding the plurality of hollow fiber membranes (10) at one end portions thereof; and a cap (30) having an internal space (30s) that communicates with each of the plurality of hollow fiber membranes (10), the cap (30) being integrated with the binding portion (20). Specifically, no other component is present between the binding portion (20) and the cap (30).

The present disclosure relates to a diffusion device, such as a blood oxygenator or gas exchanger, and a process for its production. The diffusion device is used in the removal of carbon dioxide from blood.

A cartridge is provided for dialysis or other blood processing therapy. In the cartridge, fibers may be substantially uniformly distributed near a midplane, but near an end, in the inter fiber space, there may be void flow channels, which may cause fluid flow in the inter fiber space to transition within a short region to uniform flow with minimal stagnation zones. Void flow channels may be be radially oriented, introducing fluid from the outer circumference, or axially oriented, introducing fluid along the axial direction through passageways through the potting material. The fluid flow in the inter fiber space may be perpendicular to the fibers, or radial with respect to a cartridge longitudinal axis. The cartridge may have blood flow in the inter fiber space, and flow of dialysate or ultrafiltrate in the lumens of the fibers, or the opposite situation.

A membrane humidifier for a fuel cell, of the present invention, comprises: a middle case in which a plurality of hollow fiber membranes are accommodated; a cap case coupled to the middle case; potting parts formed at the ends of the plurality of hollow fiber membranes; an assembly member disposed between the cap case and the end of the middle case so as to provide air tight coupling therebetween; and a protrusion part extending toward the edges of the potting parts from the inside of the cap case so as to provide air tight coupling between the cap case and the potting parts.

The present disclosure relates to devices and processes for the production of hollow fiber membrane bundles. The bundles are used for the manufacture of filtration and/or diffusion devices, e.g., capillary dialyzers.

The present disclosure relates to a casting device for producing a potting for a gas exchanger and a method for producing such a potting. Accordingly, a casting device is proposed for producing a potting for a gas exchanger under the influence of a centrifugal force, comprising a distributor comprising an opening and at least one continuous channel and adapted to receive a fluid potting material via the opening and to guide it via the at least one channel. The casting device further comprises a cassette defining an inner cavity for receiving gas exchanger elements and which is fluidly connected to the at least one channel. The distributor comprises at least two distributor components which, in the assembled state of the distributor, define the opening, are connected to one another in a leak-proof manner, and form the at least one channel between adjacent regions.

A cartridge for non-cryogenically separating a gas into components includes a plurality of hollow polymeric fibers, the fibers being anchored by a pair of tubesheets, each tubesheet being adjacent to a head, the tubesheet and head being joined by a clamshell retainer. The cartridge does not have a core tube. The fibers are enclosed within a sleeve, the sleeve being sufficiently thin so as to be a non-structural element. The cartridge may be inserted within a larger pressure vessel. The cartridge of the present invention can accommodate more fibers than comparable cartridges of the prior art, and therefore has greater throughput.
