AI Technical Summary

Technical Problem

Existing sterile inspection isolators consume a lot of energy when inspecting highly active drugs, require high-power fans, and occupy a large amount of external space.

Method used

The system employs a glove box, a first air inlet device, a second air inlet device, a return air duct, and a filtered air outlet duct. The connection status is controlled by a duct switching mechanism to achieve switching between the aseptic inspection modes for conventional and highly active drugs. Some air is returned to the glove box after filtration through the return air duct, reducing the power of the air inlet device and enabling internal air circulation.

Benefits of technology

It reduces equipment power consumption, meets the air volume requirements for aseptic testing of highly active drugs, and reduces equipment space occupation. It also has two ventilation modes to meet different testing needs.

Abstract

The utility model provides a high-activity medicine sterility examination isolator which comprises a glove box, a first air inlet device, a second air inlet device, a first air exhaust device, an air return channel and a filtering air outlet channel. A filtering component and a second air exhaust device are sequentially arranged in the filtering air outlet channel. A channel switching mechanism is arranged among the glove box, the air return channel and the filtering air outlet channel, and the communication state among the glove box, the air return channel and the filtering air outlet channel is controlled through the channel switching mechanism; an air return valve is arranged between the filtering air outlet channel and the air return channel and located between the air exhaust fan and the air exhaust valve. According to the utility model, the requirements of two modes of conventional sterility examination and high-activity medicine sterility examination can be met at the same time, and the power of the air inlet device (fan) can be reduced in the high-activity medicine sterility examination mode.
