The invention discloses a novel hydrophilic anti-leakage absorbable medical film and a preparation method thereof. The medical film comprises: a hydrophilic layer, an absorbing layer and an anti-leakage layer; Layers are stacked in sequence to form a hydrophilic anti-leakage absorbable medical film; the hydrophilic layer is used to stick to the damaged tissue, the absorbent layer is used to absorb tissue fluid from tissue leakage, and the anti-leakage layer Used to prevent the leakage of interstitial fluid. A novel hydrophilic anti-leakage absorbable medical membrane and a preparation method thereof of the present invention are equipped with a hydrophilic layer, an absorbing layer and an anti-leakage layer, so that the absorbing layer can well absorb tissue exudate while ensuring tissue exudation The liquid will not leak to the surrounding tissue, which improves the product's adherence, absorption, and anti-leakage, which brings great convenience to the field of surgery, especially in the repair and repair of dura mater (spinal mater) defects. There are great prospects for replacement applications. |
