Composite decellularized matrix membrane and use thereof

Abstract

The present disclosure provides a composite decellularized matrix membrane and use thereof. The composite decellularized matrix membrane prepared by the present disclosure is prepared by wrapping one layer of a polymer membrane with two layers of decellularized matrix membranes. The decellularized matrix membrane is prepared from at least a biomaterial of a porcine small intestine, a porcine bladder, and porcine skin. The polymer membrane is prepared from at least a polymer material of polycaprolactone, polydimethylsiloxane, polyurethane, polylactic acid-glycolic acid, polyvinyl alcohol, and polyhydroxy fatty acid ester. The composite decellularized matrix membrane prepared by the present disclosure can prevent calculi, makes a patient suffer less, recover faster, live better, and cost less, while medical resources are saved, and hope for treatment is also brought for some patients with a contraindication to an in-situ ileal neobladder surgery.
