Abstract

The invention provides a multi-culture cabin CO2 concentration independent adjusting method and a gas path system.The method comprises the steps that the set required CO2 concentration of each culture cabin and the real-time CO2 concentration of each culture cabin are obtained, an adjusting feedback value is obtained based on the required CO2 concentration and the real-time CO2 concentration, when the adjusting feedback value is positive, it is indicated that the CO2 gas inlet amount needs to be adjusted, and when the adjusting feedback value is negative, it is indicated that the CO2 gas inlet amount needs to be adjusted. When the adjustment feedback value is negative, it is indicated that the air inlet amount needs to be adjusted, and when the adjustment feedback value is 0, it is indicated that gas does not need to be adjusted as much as possible; the absolute value of the adjustment feedback value of each culture cabin is compared with an adjustment threshold value, and the CO2 gas inlet amount or the air inlet amount of each culture cabin is adjusted according to a comparison result. According to the CO2 concentration value set by each culture cabin, the CO2 concentration of each culture cabin can be independently adjusted.

Description

technical field [0001] The invention relates to a cell culture device, in particular, to a multi-culture cabin CO 2 Concentration independent adjustment method and gas path system. Background technique [0002] With the increasing development of biology, regenerative medicine, epidemic prevention and control and other related fields in recent years, the market demand for carbon dioxide incubators that can stably and efficiently cultivate cells is increasing. Many times, different types of cells or different batches of cells need to be put into different culture chambers. Cell culture against CO 2 Concentration and temperature requirements are very strict, when temperature and CO 2 When the concentration is destroyed, it will seriously affect the cell culture efficiency, and the worst will lead to cell death. Therefore, it is urgent to develop a method that can realize CO2 in the cultivation cabin. 2 Concentration-independent adjustment of the culture device. Contents ...
