Constant-temperature incubator for cell culture

Abstract

The invention discloses a constant-temperature incubator for cell culture and relates to the technical field of bioengineering devices. The constant-temperature incubator comprises an incubator body, a placing table is arranged in the incubator body, an air inlet is formed in the incubator body, a rotating shaft is arranged in the incubator body, a turntable is fixedly connected to the rotating shaft, the rotating shaft is rotatably connected with a breather pipe through a linear bearing, an air outlet is formed in the incubator body, and a linkage mechanism is arranged in the incubator body. By arranging a piston, a conductive rod and a ventilating fan, an air pressure difference generated when gas components in the constant-temperature incubator change pushes the piston to drive the ventilating fan to work, so that gas exchange occurs inside and outside the constant-temperature incubator to maintain an oxygen concentration in the incubator, cell culture is always in air with a proper oxygen concentration, the ventilating fan can be automatically turned off after gas exchange is completed, and thus energy consumption is reduced.

Description

technical field [0001] The invention relates to the technical field of bioengineering equipment, in particular to a constant temperature incubator for cell culture. Background technique [0002] The constant temperature incubator, also known as the water-proof electric heating cell (mold) incubator, is used for bacterial cultivation, breeding, fermentation and other constant temperature experiments in scientific research departments such as medical and health, pharmaceutical industry, biochemistry, industrial production and agricultural science, especially for cell The gas balance in the air needs to be controlled during cultivation. Most cells need oxygen during cultivation, and the culture medium used for cell culture needs carbon dioxide to maintain the stability of the pH value in the culture medium.

AI Technical Summary

Problems solved by technology

[0003] Existing constant temperature incubators only have gas exchange with the outside world when they are opened, so it is necessary to open the incubator frequently for ventilation. Since the internal environment of the incubator needs to be kept sterile and non-toxic, it needs to be cleaned every time the incubator is opened. Internal disinfection is not only very inconvenient, but also cannot keep the cell culture in an environment with the best ratio of oxygen and carbon dioxide, thus affecting the cell culture rate
