Bio-safety sterile room

Abstract

The invention provides a bio-safety sterile room. The bio-safety sterile room comprises a sterile operation chamber, an air supply duct and a purifier arranged in the air supply duct. An air inlet opening of the air supply duct communicates with the outdoor environment. An air outlet of the air supply duct communicates with the sterile operation chamber. An air outlet of the sterile operation chamber communicates with the outdoor environment. The purifier comprises a low-efficiency filter, an intermediate-efficiency filter and a plasma sterilizer, wherein the low-efficiency filter, the intermediate-efficiency filter and the plasma sterilizer are sequentially arranged in the flow direction of air. By the adoption of the bio-safety sterile room, large particles in air are filtered out firstly, and then sterilization is conducted through a plasma method; and in this way, it is guaranteed that the air flow in the sterile room is absolutely sterile and free of toxicity, the demand of a great number of bio-pharmaceutical enterprises for bio-safety-level sterile room is met, and the maintenance expense of the filters of the sterile room is greatly lowered.

Description

technical field [0001] The invention relates to the technical field of biopharmaceutical equipment, in particular to a high-safety aseptic room, and also covers other biomedical production, operation or circulation spaces outside the aseptic room, including aseptic rooms, inoculation rooms, transfer windows, and clean sheds The fields include electronic information, semiconductors, optoelectronics, precision manufacturing, medicine and health, bioengineering, aerospace, automotive spraying, fine chemicals, food and beverages and other clean environments with high requirements. Background technique [0002] Sterile rooms are generally dedicated to microbiology laboratories and can be constructed of plates and glass. A buffer room should be set up outside the sterile room, and the doors should be staggered to prevent airflow from bringing in bacteria. Both the sterile room and the buffer room must be airtight, and the ventilation equipment equipped in the room must have an ...

AI Technical Summary

Problems solved by technology

[0006] The existing aseptic rooms on the market all use filters as the dust filtration method. This method can no longer meet the requirements for many biomedical production lines with high cleanliness requirements, such as phages, viruses, some bacteria, etc. A tiny organism that is difficult to retain by filtration

Moreover, the cleaning of sterile room filters with a large number of virus microorganisms is also one of the difficulties.

Many biopharmaceutical companies are based on the consideration of reducing filter maintenance costs, so that the cleanliness level of the clean room often does not meet the requirements for use
