Integrated zero-leakage gas positive-negative pressure compatible microorganism isolation operation cabinet

Abstract

The invention provides an integrated zero-leakage gas positive-negative pressure compatible microorganism isolation operation cabinet which comprises a positive pressure cabin with a positive pressure fan and a sterile filter at the top and a glass sliding door, wherein the positive pressure cabin is surrounded by a glass front partition plate and a glass side partition plate to form a negative pressure cabin; two sealed isolation sleeves formed by overlapping and interacting an outer partition soft plate and an inner partition soft plate are arranged on the glass front partition plate; on a working table of the negative pressure cabin, a circle of negative-pressure air grid ports are communicated with a negative pressure filtering cabin with a gas filtering material; and the negative pressure fan is arranged in a fan chamber communicated on the lower side of the negative pressure filtering cabin to extract the filtered waste gas to an exhaust connector to be discharged. The zero-leakage gas positive-negative pressure compatible microorganism isolation operation cabinet provided by the invention has the beneficial effects that the device can ensure that the cells and bacteria cultured in a microorganism experiment process are free from the contamination and interference of other bacteria in a sterile positive pressure environment, and harmful microorganisms and gases inside can be isolated and shielded by the negative pressure cabin so as to prevent leakage and consequent environmental pollution and occupational injury; and the device is widely applied to the scientific research fields such as environmental protection, medical scientific research, military security and the like.

Description

technical field [0001] The invention relates to an integrated zero-leakage gas positive and negative pressure compatible microbial isolation operation cabinet. Background technique [0002] In recent years, a large number of experiments on the effects of bacteria, cell culture and drug intervention have been carried out in environmental protection, military security, biological science, medicine and health, animal botany, respiration and toxicology research. In cell, bacteria culture and scientific experiments, a capable Ensure the normal survival, growth and experiments of cells in a clean, dust-free, sterile gas positive pressure environment. At the same time, bacteria and cells themselves have a certain possibility of infection, especially when some harmful gas aerosols are used for cell exposure tests. It is necessary to aerosolize some toxic and harmful substances, which are easy to spread and pollute the operating environment, and even cause harm to the operator, such ...

Problems solved by technology

[0005] The beneficial effects of the present invention are: providing an integrated zero-leakage gas positive and negative pressure compatible microorganism isolation operation cabinet device, using a sterile environment with positive pressure inside to cultivate and test single microorganisms such as cells and bacteria, surrounded by a It can collect all the gas discharged in the positive pressure chamber, and there is no negative pressure chamber that leaks at all, and there is a device with a sealed isolation sleeve to facilitate the operation of the experiment at any time, which not only solves the problem of ensuring that the cells, bacteria, etc. In the positive pressure environment, it is free from interference caused by other bacteria pollution, and it solves the scientific research problem that harmful microorganisms or harmful gases can be shielded from harmful microorganisms or harmful gases that cause harm to the environment and operators by isolating negative pressure. Widely used in the research fields of military security, biological science, medicine and health, animal botany, respiratory and toxicology
