Air bubble removal device for removing air bubbles from medium and medium circulating cell cultivation system including the same

A medium circulating cell cultivation system, comprising:

• a cell cultivation device in which at least one support to which cells to be cultured are attached is installed;
• a medium supply device in which a predetermined amount of culture medium for culturing the cells is stored therein;
• a cell supply source in which a predetermined amount of seeding medium including cells to be attached to the support is stored;
• an air bubble removal device for removing air bubbles from the culture medium introduced from the medium supply device or the seeding medium introduced from the cell supply source, and then supplying the same to the side of the cell cultivation device;
• and
• a pump for circulating the culture medium,
• wherein the air bubble removal device comprises:
• a housing which includes an inner space for storing a predetermined amount of the medium, an introduction port through which the medium is introduced from the outside into the inner space, and a discharge port through which the medium in a state where air bubbles have been removed is discharged from the inner space to the outside;
• and
• a support part which is coupled to the housing so as to maintain the housing in a state of being spaced by a predetermined height from a bottom surface,
• wherein the inner space includes a first space which is filled with a predetermined amount of the medium and a second space which is positioned above the first space and not filled with the medium, and
• wherein the first space and the second space are distinguished through the water level of the medium that is introduced into the inner space from the outside through the introduction port.
