Unstable mixing ratio control: complete reliance on manual operation can not guarantee the consistency of the mixing ratio of physiological saline and human albumin in each configuration, which is easy to cause mixing ratio deviation due to improper operation, and further affect the drug efficacy and treatment effect.
[0007] 5. Lack of automation and standardization: the existing method does not introduce automatic control equipment, lacks effective automation management of operation process, and cannot realize standardized production, resulting in uncertainty of the quality and effect of each configuration.
