  • Publication number: 20190062691
    Abstract: The present invention relates to a filter device for capturing a target cell and a target cell collecting method using the same. A filter substrate by which a target cell is captured is formed of an elastic material. When blood passes, the size of a lattice hole of the filter substrate by which the target cell is captured is reduced. When the blood completely passes, the size of the lattice hole of the filter substrate by which the target cell is captured is restored, so that a destruction rate of the target cell may be reduced and a collect rate of the target cell may be increased.
