Abstract

An apparatus for purifying blood including a plasma separation filter separating plasma from blood; an internal diaphragm inserted in between the plasma separation filter and the absorption filter to cover the side wall of the plasma separation filter; an absorption filter for filtering the plasma, covering the plasma separation filter; and a housing coupled to cover the absorption filter. When blood flows into one inner side, the plasma separately passes through a side wall and blood cells to be discharged through the other inner side. An internal diaphragm through-hole in a side wall of the internal diaphragm through which the plasma passes, and a plasma outlet in a side wall of the housing. The miniaturization of the apparatus is realized by unifying the plasma separation filter and the absorption filter into one body.
