Embodiment 1
[0078] The freeze-dried powder injection of sodium carbosulfonate in this embodiment consists of the following raw materials:
[0079] Sodium carbosulfonate 20g, water for injection 2000mL;
[0080] Its preparation method comprises the following steps:
[0081] (1) Take 80% of the selected volume of water for injection, add the selected weight of sodium carbosulfonate, stir until completely dissolved, adjust and control the water temperature to 75°C to obtain solution A;
[0082] (2) Take 20% of the selected volume of water for injection, add it to the solution A, stir until it is completely dissolved, adjust and control the pH value to 5.0-6.0, and pre-filter it through a plate and frame filter to obtain solution B;
