Method for solving crystal substance precipitation of mixed sugar electrolyte injection after disinfection

The invention provides a method for solving crystal substance precipitation of a mixed sugar electrolyte injection after disinfection, which comprises the following steps: step one, dissolving sodium chloride and anhydrous glucose in injection water which accounts for 20-40% of a prescription amount, adjusting the pH by a pH adjusting agent to obtain a mixed solution; step two, dissolving fructose, xylitol, sodium acetate and dipotassium hydrogen phosphate in the mixed solution, adding active carbon, stirring, filtering to obtain a filtrate; step three, mixing the filtrate with injection water dissolved with sodium bisulfite, zinc sulfate, magnesium chloride and calcium chloride, adding active carbon, supplementing injection water to obtain the prescription amount, stirring, standing, adjusting the pH by the pH adjusting agent, filtering, and performing disinfection. Through controlling the using amount of the pH adjusting agent, the method effectively prevents the defect of crystal precipitation of the injec
