BLOOD SEPARATING DEVICE

PURPOSE: A blood separation apparatus is provided to separate the each component of blood more accurately by the control of the pore size of a blood separation filter and the centrifugal force generated by rotating a dual disc. CONSTITUTION: A blood separation apparatus(1) comprises an upper disk(100) which is provided with a blood separation column(120) comprising a sample loading part(110) and a blood separation filter(121); a lower disc(200) which is provided with at least two blood component storage parts(211,212,213) capable of being connected with the blood separation column, respectively and storing the each blood component separated by the blood separation filter; and a rotation engagement part(300) which comprises a jointing gear(310) rotating at least one of the upper and lower discs, and a rotation shaft(320) applying the centrifugal force to the blood sample.
