AI Technical Summary

Technical Problem

When replacing filter components in existing injection production equipment, the sterilization space is connected to the external environment, which allows bacterial contaminants to easily enter, affecting the sterilization and purification effect and increasing the risk of product non-compliance.

Method used

The sterilization equipment is equipped with a purification mechanism, including components such as a protective tank, gamma emitter, nanofiber filter, and ultraviolet lamp. Through multi-stage filtration and sterilization, the equipment is sealed to prevent external contaminants from entering and to achieve deep sterilization.

Benefits of technology

It improves the purification efficiency and cleanliness of injection solutions, ensures sterility assurance levels, reduces bacterial contamination during equipment changeover, and enhances production continuity and product quality.
