Problems solved by technology

[0004] 1. The existing large infusion solution (100ml: 3.224g, 250ml: 8.06g) has crystallization at slightly lower than normal temperature (10°C), so it is prone to crystallization at low temperatures during transportation and clinical use
[0005] 2. Due to the continuous contact with the rubber stopper of the infusion bottle, the Chinese medicinal liquid for large infusions makes the clarity of the solution difficult to pass
[0006] 3. Xylitol is used as the isotonic agent of the large infusion solution, which has limitations in clinical use
[0007] Based on the above-mentioned prior art and existing problems, although those skilled in the art may think of combining the existing freeze-dried powder injection technology of other medicines to propose the idea of ​​preparing the freeze-dried powder injection of the compound amino acid related to the present invention, due to the preparation of freeze-dried powder Powder injection requires a relatively low amount of water, and compound amino acids have poor solubility in this amount of water, so far it has not been possible to prepare compound amino acid freeze-dried powder injections that meet the medicinal requirements
