Preparation method and application of clean fine-core sterile heterogeneous sigmoid membrane

Abstract

The invention discloses a clean fine-core sterile heterogeneous sigmoid membrane as well as a preparation method and clinical application thereof. A clean fine-core sterile heterogeneous sigmoid membrane biological novel material is successfully manufactured. A pig sigmoid membrane is taken as an animal model and subjected to experimental investigation of substrate application. The heterogeneous sigmoid membrane prepared by the preparation method disclosed by the invention can block body stress response of a patient with extensive burns, can lower super-high metabolism and can keep the remaining skin structure necessary for later-period skin regeneration. After the wound surface is cleaned and sterilized in a treatment process, the dressings can be not changed, skin can be not grafted, operation can be not carried out, the wound surface is protected from pollution and complication is avoided, so that cure rate for extensive burns is improved; moreover, scar hyperplasia is restrained, and disability rate of the patient is reduced.

Description

technical field

[0001] The invention belongs to the technical field of disposable sterile medical devices, in particular to the field of biological dressings for surgical use in which the core and wall of the biological "B film" are driven away and presents a grid-like membrane, and in particular relates to "clean fine nuclei sterile heterogeneous B membrane matrix" and its preparation method and application. Background technique

[0002] Disposable sterile medical biological dressings play an important role in saving lives in the treatment of patients with extensive burns and scalds. With the rapid development of tissue engineering, great progress has been made in the basic research and clinical application of allogeneic skin substitutes. However, there are still some problems to be solved before skin transplantation. In recent years, dermatologists at home and abroad have been seeking for good compatibility of wound repair covering materials, in order to eliminate reject...
