AI Technical Summary
In existing technologies, the water supply pipes are long and prone to water accumulation after completion, leading to microbial growth and affecting the quality of water for injection.
A water replenishment device for a water-for-injection storage tank was designed. By setting a first branch pipe and a first valve at one end of the replenishment pipe near the storage tank, and using a conductivity detector to detect that the water quality is qualified, drainage and replenishment are carried out. Combined with steam sterilization, this prevents the growth of microorganisms from water accumulation.
This effectively avoids microbial contamination during water replenishment pipeline accumulation, ensuring the quality of water for injection meets standards.
