  • Patent number: 12257554
    Abstract: Methods herein disclosed include methods of producing a nanoporous membrane by coating a planar substrate (204) with a solution (solution tank 201) containing a reactive metal adatom. The coated planar substrate can then be perforated by initiating a redox reaction between the reactive metal adatom and the planar substrate that causes the reactive metal adatom to remove material, forming nanoscale pores in the planar substrate that result in a nanoporous planar material. This nanoporous planar material can be formed into a nanoporous membrane.

  • Patent number: 12178944
    Abstract: A device for determining a dialysis efficiency/dialysis dose of an extracorporeal blood treatment process has a radiation source, a cuvette, a detection unit and a control unit. The radiation source emits radiation, the intensity of which is controlled by adjusting a current intensity applied to the radiation source. The cuvette is preferably provided with an inlet and outlet, and is penetrated by radiation emitted by the radiation source. The detection unit detects the intensity of the radiation after the radiation passes the cuvette. The control unit determines the dialysis efficiency/dialysis dose from the intensity detected by the detection unit. The control unit, which is connected to the radiation source and detection unit, reduces the intensity of the radiation by adjusting the current intensity during the extracorporeal blood treatment process at least once, based on a drop in concentration of substances excreted in the urine in the dialysis fluid.

  • Patent number: 12179152
    Abstract: The present invention relates to a crossflow membrane module configured to separate a feed fluid into a permeate fluid and a residue fluid across one or more membrane sheet(s). The crossflow module comprises a second end offset from a first end along the first direction where an inlet is provided at the first end and an outlet is provided at the second end. The one or more membrane sheet(s) each have a first portion and a second portion. A conduit is adjacent to the first side of each membrane sheet and is configured to receive and output the permeate fluid separated from the feed fluid. The second portion of the membrane sheet has a greater permeance for a major component than the first portion such that the second part of the permeate fluid, which is generated by separation across the second portion of the membrane sheet, has a higher concentration of the major component than the first part of the permeate fluid, which is generated by separation across the first portion.
