Here, the substrate member to prevent the cells (C) from being damaged while the cells (C) positioned above the elastic culture unit 130 are in close contact with the elastic culture unit 130 and the compression unit 140 . A 142 may be provided between the elastic culture unit 130 and the compression unit 140 .

At this time, the substrate member 142 may be formed of a sponge material or a gel-like material to prevent damage to the cells (C), but is not toxic to the cells (C), and the cells (C) are not toxic. A material in which micropores are formed so that the medium can be moved through the circulation unit 220 may be more efficient.

For example, the matrix member 142 is not toxic to the cell (C), and since micropores must be formed so that the medium can be moved, an environment similar to the extracellular matrix of the cell (C) can be created. Using alginate, a substance that can be used, no toxicity acts on the cell (C), the medium moves along the micropores of alginate, and similar to the extracellular matrix existing on the outside of the cell (C) inside the human body environment can be created.

As described above, when air is moved through the supply unit 120 into the enclosed space formed by the elastic culture unit 130 and the inner wall 114, the upper portion of the elastic culture unit 130 is formed by the tension providing unit ( 110) is expanded in a hemispherical shape toward the upper portion, and the compression unit 140 may be deformed toward the upper portion of the tension providing unit 110 as the elastic culture unit 130 expands.

On the other hand, the support unit 150 may be formed with a medium passage for preventing the medium from overflowing by the elastic culture unit 140 and the compression unit 130 .

A function may be described in more detail with reference to FIGS. 5 to 8 based on the above-described configuration.

Specifically, FIG. 5 is a view showing a situation in which air is injected into an elastic culture unit of a culture apparatus and a culture system that provides an environment similar to a human body including a cell culture unit according to an embodiment of the present invention, FIG. 6 is 7 is a view showing a situation in which a compressive force is applied to cells of a culture apparatus and a culture system that provide an environment similar to a human body including a cell culture unit according to an embodiment of the present invention. 8 is a diagram illustrating a situation in which a culture device and a culture system providing an environment similar to a human body including a cell culture unit are moved and FIG. 8 is an environment similar to a human body including a cell culture unit according to an embodiment of the present invention It is a view showing a situation in which the culture equipment and culture system that provide the medium are moved as viewed from the top.

First, as shown in FIG. 5 , when air is injected into the enclosed space formed by the elastic culture unit 130 and the inner wall 114 through the supply unit 120 , the elastic culture unit 130 that can be stretched is formed at the upper part. It expands toward a hemispherical shape, and tension may be applied while the cells (C) attached to the upper portion of the elastic culture unit 130 are pulled toward the circumference of the elastic culture unit 130 .

As described above, as the elastic culture unit 130 expands, tension can be applied by pulling the cells (C) toward the circumferential direction of the elastic culture unit 130, and since the cells (C) are pulled in all directions, conventionally There is an effect of creating an environment similar to the internal environment of the human body rather than the tension acting only on both sides of the cell (C).

When the elastic culturing part 130 is expanded upward, the compression part 140 positioned on the elastic culturing part 130 expands the elastic culturing part 130 while the tension providing part 110 . Pressure may be applied to the cell (C) by a force that is deformed upward and returns to a position before deformation.

At this time, since the cells C may be damaged by the pressure applied by the compression unit 140 , the substrate member 142 is disposed between the compression unit 140 and the elastic culture unit 130 as described above. ) may be provided.

Here, as shown in FIG. 7 , in the substrate member 142 , fine pores are formed so that the medium and oxygen can move to allow the cells (C) to grow, and the drug injected through the inlet 220 and It can act on the cell (C) together.

In more detail, as shown in FIG. 8, the medium is moved between the compression unit 140 and the elastic culture unit 130 through the micropores formed in the substrate member 142, and the cells (C) is delivered to, and may be moved toward the discharge unit 240 along the micropores of the substrate member 142 .

Based on the above-mentioned contents, the cell (C) applies the tension applied inside the human body as the elastic culture unit 130 expands and the tension is applied, and the compressive force is pressurized by the force that the compression unit 140 restores. and compressive force is applied, and an environment similar to the extracellular matrix is created by the matrix member 142, so that it can grow in an environment more similar to the human body.

As such, when the drug is injected into the cell (C), if the cell (C) does not exert tension and compressive force, there may be a slight difference in the time and application time of the drug. It may be more effective by applying both tension and compression force in the cell culture unit 100 according to an embodiment.

In addition, when the drug is injected into the cell (C), when directly injected into the cell (C), or when the drug is put into the cell (C) and applied, the drug is passed through the blood vessel inside the human body. Similar to how the drug is injected, since it acts on the cells (C) through the micropores of the matrix member 142, there is an effect that the effect of the drug can be confirmed more similarly in the human body.

When a plurality of the cell culture units 100 are used to culture the cells C using the cell culture unit 100 described above, there is a space inside so that the cell culture units 100 can be arranged. The housing in which this is formed and the supply unit S in which air is moved toward the cell culture unit 100 may be provided.

Here, the supply unit (S) may be formed as a passage divided to be connected to the bottom surface of each of the plurality of cell culture units ( 100 ), and the supply unit (S) is a plurality of the cell culture units ( 100 ), respectively It may be formed to have the same length as

For example, the at least one supply unit (S) connected to the cell culture unit (100) is divided at least once to communicate with the cell culture unit (100), and the divided supply unit (S) is Each distance (A) from the initially divided position to the plurality of cell culture units 100 may be the same.

As described above, preferred embodiments according to the present invention have been reviewed, and the fact that the present invention can be embodied in other specific forms without departing from the spirit or scope of the present invention other than the above-described embodiments is a fact having ordinary skill in the art. It is obvious to them.
