  • Patent number: 11369724
    Abstract: A system for collecting plasma comprises a separator to separate whole blood from a donor into a plasma product and a second blood component, an anticoagulant line to combine anticoagulant with the whole blood, a touchscreen, and a controller. The controller is configured to receive donor parameters electronically from a donor management system. The controller is configured to use a target volume for raw plasma which is based at least in part on donor height and weight used to calculate total donor blood volume, the target volume for raw plasma based on the total donor blood volume. The controller is configured to control the system to operate draw and return phases to withdraw whole blood from a donor and return the second blood component to the donor until a volume of raw plasma in the collection container equals the target volume of raw plasma.

  • Patent number: 11351475
    Abstract: A method includes supplying a supersaturated brine stream having a plurality of minerals and anti-scalant from a water treatment system to a gypsum removal system disposed within a mineral removal system. The gypsum removal system includes a gypsum reactor that may receive the supersaturated brine, may deactivate the anti-scalant such that gypsum precipitates from the supersaturated brine, and may generate a gypsum slurry having a mixture of desupersaturated brine, precipitated gypsum, and the anti-scalant in solution with the desupersaturated brine. The method also includes supplying gypsum seed crystals to the gypsum reactor. The gypsum seed crystals may precipitate the gypsum from the supersaturated brine to generate the gypsum slurry. The method also includes directing a first portion of the gypsum slurry from the gypsum reactor to a gypsum settler.

  • Patent number: 11351291
    Abstract: The invention provides a method and an apparatus or system for dialysis. The method and apparatus or system are useful for removing an undesirable protein-binding substance such as a toxin from a biological fluid such as blood or blood plasma. As such, the method and apparatus or system are useful for treating a subject in need of dialysis such as a subject suffering from hepatic disease. The methods feature a) dialyzing a biological fluid against a dialysis fluid containing an adsorber for a protein-binding substance to be removed through a semipermeable membrane, b) adjusting the dialysis fluid so that the binding affinity of the adsorber for the protein-bound substance to be removed is lowered and the substance to be removed passes into solution, and c) balancing the volume or flow of one or more fluids in the apparatus or system suitable for dialyzing a biological fluid containing a protein-binding substance to be removed.

  • Patent number: 11324869
    Abstract: The present invention is a system to continuously monitor, in real-time, the small molecules being dialyzed during hemodialysis treatment using Raman spectroscopy and press control algorithms. By monitoring the treatment, the amount of water needed per dialysis treatment is drastically reduced by optimizing analyte saturation and removal of wastes. This will significantly conserve water and reduce the cost of dialysis treatments, possibly reducing the amount of time necessary for dialysis treatment, improving quality of life for patients during and after treatment, and reducing the costs of building new treatment centers as well as operating costs.

  • Patent number: 11325099
    Abstract: A water filtration system is provided that comprises a combination of two components: silver nanoparticles immobilized on a porous carbon solid matrix and calcium carbonate silver nanoparticles. The silver nanoparticles immobilized on the porous carbon solid matrix are prepared in a one-step wet ball milling process that does not use an environmentally hazardous reducing agent or an organic stabilizer. The calcium carbonate in the calcium carbonate silver nanoparticles is preferably isolated from egg shells. The two filter components can be present in any ratio but an approximate 50:50 ratio is preferred. Also provided is an in situ method of preparing silver nanoparticles on active charcoal. Powdered activated charcoal and silver nitrate are mixed together in a mixture of ethanol and water to form a charcoal-silver nitrate solution which is then subjected to ball milling in the presence of polypropylene glycol to produce silver nanoparticles on active charcoal.

  • Patent number: 11285251
    Abstract: A plasmapheresis system and a method for operating a plasmapheresis system are provided by which the volume/weight of anticoagulated plasma that is collected is optimized. In one example, a nomogram is provided that utilizes the donor's hematocrit to calculate the volume/weight of raw plasma within a plasma product having the maximum volume permitted by the FDA nomogram. In a plasmapheresis procedure having multiple collection phases followed by a reinfusion cycle in which concentrated red blood cells are returned to the donor, the volume of plasma product to be collected is calculated prior to the start of each collection cycle to account for the donor's increasing hematocrit, thus resulting in a greater total volume of plasma product to be collected during the plasmapheresis procedure.

  • Patent number: 11260155
    Abstract: A portable hemodialysis system is provided including a dialyzer, a closed loop blood flow path which transports blood from a patient to the dialyzer and back to the patient, and a closed loop dialysate flow path which transports dialysate through the dialyzer. In addition, the hemodialysis system includes two reservoirs which can be alternately placed in the dialysis flow path using various controllable fluid valves. The hemodialysis system may include a sorbent filter in the dialysate flow path which filters used dialysate.
