Disclosed is a regeneration membrane applicable to tissue repair engineering. The regeneration membrane comprises: a first porous layer and a second porous layer that are adjacent to and bonded to each other. A plurality of pores formed and distributed on the first porous layer and the second porous layer communicate with outside environment. The pore size of the first porous layer is greater than the pore size of the second porous layer. The regeneration membrane is characterized by unsymmetrical inflow and outflow permeability and is a regeneration membrane of high unidirectional permeability. The term high unidirectional permeability is referred to either high inbound flow or high outbound flow and high outbound or inbound flow mode applied to a damaged area is determined according to the requirement of the damaged area.一種應用於組織修復工程之再生膜,該再生膜包含:鄰接結合的一第一孔隙層和一第二孔隙層;該第一孔隙層和第二孔隙層分佈有多數個與外部環境相連通的孔隙,且該第一孔隙層的孔隙尺寸大於該第二孔隙層的孔隙。該再生膜具有流入與流出通透率(inflow and outflow permeability)不對稱之特性,為一高單向通透率之再生膜,所謂的高單向通透率可以是高內流或高外流,需藉由損傷部位之需求,而決定對損傷區域採高外流或高內流應用模式。10...再生膜11...第一孔隙層111...孔隙12...第二孔隙層121...孔隙13...第一表面14...第二表面
