Embodiment 1

[0050] A preparation method of a hemodialysis concentrate in this embodiment comprises the following steps (such as figure 1 shown):

[0051] (1) Put the raw materials of hemodialysis A concentrated solution into the liquid mixing tank and stir and dissolve to prepare 100L of A concentrated solution;

[0052] (2) The solution in the liquid distribution tank is subjected to secondary filtration with filter elements of 1 μm and 0.22 μm;

[0053] (3) Mix the solution in the liquid distribution tank with the ozone generated by the ozone generator (filtered by a 0.22μm filter element) through a gas-liquid mixing pump and then input it into the storage tank. The pumping flow rate is 500L / h, and the ozone generated by the ozone generator Pass it into the gas-liquid mixing pump through the pipeline, fully mix and sterilize with the concentrated liquid A in the pump;

[0054] (4) The solution in the storage tank is pumped back to the liquid distribution tank by the circulation pump; ...

Embodiment 2

[0061] A kind of preparation method of hemodialysis concentrate of the present embodiment comprises the following steps:

Abstract

The invention discloses a preparation method of a hemodialysis concentrated solution. The preparation method comprises the following steps that (1) the hemodialysis concentrated solution is prepared in a solution mixing tank; (2) the solution in the solution mixing tank is subjected to second-level filtration; (3) the solution in the solution mixing tank and ozone generated in an ozone generator are input to a storage tank after being mixed through a gas and liquid mixing pump; (4) the solution in the solution mixing tank is pumped back to the solution mixing tank through a circulation pump; (5) the solutions in the solution mixing tank and the storage tank are mixed in a circulative mode until the ozone concentration of the solution in the storage tank reaches 0.050-0.100 mg/L; (6) the hemodialysis concentrated solution is obtained through filling. The preparation method is simple in operation, quick, efficient, and easy to industrialize. Compared with a conventional method, according to products prepared through the method, initial contaminating bacteria in the concentrated solution are reduced, the storage period is prolonged, product quality is better guaranteed, and using safety of a patient is guaranteed.

Description

technical field [0001] The invention relates to the technical field of medicine, in particular to a hemodialysis concentrate and a preparation method thereof. Background technique [0002] Hemodialysis concentrate contains A concentrate and B concentrate. A concentrate is mainly composed of sodium chloride, potassium chloride, calcium chloride, magnesium chloride, acetic acid and purified water. B concentrate is composed of sodium bicarbonate and purified water. . In hemodialysis, concentrated solution A and concentrated solution B are used together to form dialysate. Its main function is to correct electrolyte and acid-base balance disorders of dialysis patients and remove metabolic waste in the body. [0003] During the hemodialysis process, the dialysate and the blood undergo material exchange through the dialyzer filter membrane, and some low-molecular substances can freely pass through the dialyzer filter membrane, enter the dialysate from the blood or enter the blood ...
