Problems solved by technology

At present, the preparation of this product is a water injection, and there are many inconveniences in the process of use: 1. In actual operation, the liquid needs to be pumped many times, and the preparation is easily contaminated by bacteria, resulting in unqualified heat source
2. In actual clinical practice, many diseases require reducing the amount of fluid infusion, but water injection cannot solve the problem
3. In the cold season, especially in the north and alpine areas, there are inconveniences in transportation and storage
4. The liquid preparation is damaged, which will easily cause pollution to the packaging; 5. The application range is narrow
