Elastic protection tube for a hollow fiber blood processing apparatus

A blood processing apparatus includes a housing, a shell, a fiber bundle, and an elastic tube. The housing has a blood inlet and a blood outlet and the shell is situated in the housing and configured to receive blood through the blood inlet. The shell includes a surface and one or more apertures extending through the surface to permit the blood to flow to an exterior of the shell. The fiber bundle includes gas exchanger hollow fibers situated about the shell such that gas flows through and the blood flows across the gas exchanger hollow fibers. The elastic tube includes a fiber web situated about the fiber bundle and configured to elastically constrain and protect the gas exchanger hollow fibers during the insertion into the housing. The fiber web has a pore size that permits the blood to flow across the fiber web without filtering micro-emboli from the blood.

Ceramic membrane module with external frame assembly and related methods

A method for forming a ceramic membrane module system includes disposing at least one membrane (118) within a housing (120), the membrane (118) having capillaries therein. The method includes sealing the first housing end (122) and capillaries, applying force to the removable gasket with an external frame assembly (200), and disposing potting material into the housing (120) without plugging the capillaries with the potting.

METHOD FOR ATTACHING WATER-REPELLENT FILTER TO INLET OR OUTLET OF AIR VENT FORMED IN THERMOPLASTIC RESIN MOLDED ARTICLE, THERMALLY PROCESSING TIP AND THERMALLY WELDING TIP FOR MOLDING FILTER ATTACHMENT PORTION AND FOR ATTACHING FILTER, AND MOLDED ARTICLE
20200215764 · 2020-07-09 ·

A method attaches a liquid-repellent filter to an air vent of a resin molded article accommodating a component/electronic part. A thermal processing tip and a thermally welding tip and a molded article are provided. The thermal processing tip (22) forms a filter attachment surface (14) at the inlet or outlet of an air vent (16) in a thermoplastic resin molded article (13). A filter fixing rib (15) is formed around the attachment surface. The porous filter (18) is dropped onto the filter attachment surface, and a thermal welding tip (2) is used to melt the filter fixing rib such that the melted resin flows onto and covers a circumferential edge portion of the filter, penetrating the body of the filter. The melted resin penetrating the filter 18 and covering the circumferential edge portion of the filter are cooled to solid, whereby the filter is fixed to the filter attachment surface.

METHOD AND TOOL FOR EXTRACTING A FILTER ELEMENT FROM A PIPELINE
20200188821 · 2020-06-18 ·

The invention relates to a method for uninstalling a filter element from a pipeline, said filter element having a substantially central opening and an outer contour that substantially corresponds to an inner contour of said pipeline, wherein: a tool is inserted into said substantially central filter element opening, which opening runs in the longitudinal axial direction of said filter element, said tool is subsequently enlarged in at least one subsection of its peripheral surface in an extension running substantially perpendicularly to the longitudinal axial direction of the filter element, and is force and/or form-fittingly connected to an inner lateral surface of the substantially central filter element opening, said filter element finally being pushed with the tool in the longitudinal axial direction until the filter element projects out of the pipeline and is removed from the pipeline.

Method for operating lifting set including lifting apparatus and water device

A lifting set includes a lifting apparatus and a water treatment device. In lifting the water treatment device, an engaging member attached to a first attaching position of a frame of the lifting apparatus pivots in a first direction by sliding along a corresponding engageable portion of the water treatment device as the lifting apparatus approaches the water treatment device, and then automatically engages with the engageable portion by pivoting back to a vertical position by weight thereof while the lifting apparatus is further lowered. In installing the water treatment device, the engaging member attached to a second attaching position engages with the engageable portion at a pivoted position pivoted in a second direction, and when the lifting apparatus is further lowered after installation, the engaging member automatically disengages from the corresponding engageable portion by pivoting back from the second pivoted position to the vertical position by weight thereof.

Each filtration module contains at least one individual filtration unit for executing a filtration process independent of the other filtration units, first input ports for receiving a first type of fluids, second input ports for receiving a second type of fluids, and exit ports for outputting unused system fluids. First type fluids are process fluids are specific to the filtration processes executed in individual filtration units. Second type fluids are system fluids not specific to filtration processes executed in the individual filtration units. The second input and exit ports establish inter-module connections so system fluids can be forwarded from one filtration module to an adjacent filtration module of the filtration system.
