Air interchanger for cell culture

Abstract

The invention relates to the technical field of cell culture, and discloses an air interchanger for cell culture. The air interchanger comprises a base, a box body, a placement rack, a box door, an air discharging assembly and an air inlet assembly; the top end of the base is fixedly connected with the box body; the bottom end of the inner wall of the box body is fixedly connected with the placement rack; the right side of the box door is rotatably connected with the front surface of the box body; the right side of the box door is movably connected with the air discharging assembly; the right side of the inner wall of the box body is movably connected with the air inlet assembly; when the box door is opened, a second baffle does not partition an air inlet pipe any longer; an air purifier conveys clean air into the box body from the air inlet pipe; when the box door is completely closed, a first baffle does not partition an air outlet pipe any longer, so that dirty air in the box body is exhausted through the air outlet pipe; therefore, the air in the box body is in a clean state; dust and some bacteria in the air are prevented from entering a culture dish to hinder normal growth and development of cells; and the failure rate of cell culture is reduced.

Description

technical field [0001] The invention relates to the technical field of cell culture, in particular to a ventilation device for cell culture. Background technique [0002] In various studies on cell production and development in biology and medicine, cells must be cultured. At this time, cell culture devices must be used, and a completely sterile environment must be achieved during cell culture. Existing cell culture The device is to put the cells to be cultured into a petri dish, and then put the petri dish into an incubator for culturing. The incubator needs to be sterilized frequently to ensure the smooth progress of the cell culture process. Even so, there may still be some cells that cannot Normal culture, this is because in the process of opening and closing the incubator, the external air will meet with the internal air of the incubator, so that the external air enters the incubator. It is well known that there are various dusts and bacteria in the air. After dust and...

[0002] In various studies on cell production and development in biology and medicine, cells must be cultured. At this time, cell culture devices must be used, and a completely sterile environment must be achieved during cell culture. Existing cell culture The device is to put the cells to be cultured into a petri dish, and then put the petri dish into an incubator for culturing. The incubator needs to be sterilized frequently to ensure the smooth progress of the cell culture process. Even so, there may still be some cells that cannot Normal culture, this is because in the process of opening and closing the incubator, the external air will meet with the internal air of the incubator, so that the external air enters the incubator. It is well known that there are various dusts and bacteria in the air. After dust and bacteria enter the incubator, they will fall into the petri dish, which will pollute the petri dish and make the cells unable to develop normally. In particular, some molds multiply rapidly, which will squeeze the growth environment of the cells and cause the cells to die. Therefore, We propose an aeration device for cell culture that prevents contamination of petri dishes
