摘要: A standard reagent kit for analysis of a dialysis fluid includes (1) a vial A filled with an aqueous solution A including an electrolyte component capable of reacting with carbonate ion to form a precipitate, and (2) a vial B filled with an aqueous solution B including at least either one of bicarbonate ion and carbonate ion. At least the vial B is a water-repellent resin vial, and provides a standard reagent for analysis of a dialysis fluid. Precipitation is prevented for a long period of time, a change of a content of bicarbonate ion is controlled, a complicated procedure is not required for preparation thereof, handling thereof is easy, and checking of a dialysis fluid after preparation thereof can be performed easily and accurately at medical treatment site.

摘要: A blood purifier comprises hollow fiber membranes allowing a dialysing fluid or a filtrated fluid to flow outside. The membrane has an effective length of 10 mm or more and 150 mm or less. A maximum value of a permeation flux Jv obtained by dividing a volume of a permeate fluid permeating through the membranes by a membrane area of the hollow fiber membranes and time, is represented as Jvmax. A linear velocity of blood flowing in the membrane is represented as uB. A pressure difference between blood flowing inside the membranes and a fluid flowing outside the membranes is represented as TMP. When a filling blood volume into the membranes per unit membrane area is 20 mL/m2 or more and 35 mL/m2 or less and Jvmax/uB has a value of 0.00015 or more and 0.0006 or less, a TMP change rate is 0.95 or more and 1.05 or less.
