Embodiment 1
[0037] (1) Concentrated preparation of the electrolyte solution in room A: put calcium chloride, magnesium chloride and lactic acid into water for injection respectively, stir to dissolve, add activated carbon, stir evenly, first filter through a 1.00 μm polyethersulfone filter element, and then pass through a 0.45 Filter with μm polyethersulfone filter element to obtain concentrated solution in room A;
[0038] (2) Dilute preparation of the electrolyte solution in room A: Add water for injection to the required amount to the concentrated solution in room A obtained in step (1), stir evenly, and filter through a polyethersulfone filter element with a pore size of 0.22 μm until the liquid medicine is clear Finally, adjust the pH value to 2.15 to obtain the electrolyte solution in room A;
[0039] (3) Concentrated preparation of buffer solution in room B: Put sodium bicarbonate and sodium chloride into water for injection respectively, stir and dissolve, add activated carbon, st...
