High-safety plasma sterile room

Abstract

The invention provides a high-safety plasma sterile room. The high-safety plasma sterile room comprises a sterile operation room, an air supply pipe, an air return pipe and a purifier arranged in the air supply pipe. The purifier comprises a low-efficiency filter, a medium-efficiency filter, a plasma sterilizer and a monitoring upper computer, the low-efficiency filter, the medium-efficiency filter and the plasma sterilizer are sequentially arranged along the gas flowing direction, the monitoring upper computer is used for monitoring the plasma sterilizer, the plasma sterilizer comprises a shell and a plurality of electrode tubes arranged in the shell in a matrix manner, every electrode tube comprises an inner electrode, an insulator and an outer electrode tube which are arranged concentrically, and a specific gap is reserved between each insulator and the corresponding outer electrode tube. The high-safety plasma sterile room has the advantages that large particles in air are filtered out firstly, and sterilization is achieved through a plasma method, so that absolute sterility and non-toxicity of circulating air in the sterile room are guaranteed, the requirements of a great number of bio-pharmaceutical enterprises on bio-safety-level sterile rooms are met, and maintenance cost of the filters in the sterile room is also reduced greatly.

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

[0007] In addition, for biological laboratories with potential, high or unknown transmission routes, ordinary safety laboratories usually use micro-negative pressure to prevent the spread of pathogenic microorganisms, which has potential safety hazards and insufficient protection for experimenters. The filter fails, and the pathogenic microorganisms in the air are repeatedly circulated in the air, and the chance of harm to people increases
