Problems solved by technology

[0002] In the medical field, there are diseases with incomplete and damaged tissues, which require tissue repair materials to repair. Collagen sponge is a medical consumable commonly used in surgery. It can act as a filler, quickly stop bleeding, prevent adhesions, and accelerate wound healing. Complications, in neurosurgery, orthopedics, gynecology, general surgery, operating room, etc., is a kind of tissue repair materials. The existing tissue repair materials have low fluidity and low plasticity, which is not convenient for tissue repair. This method Preparation of foamed biomaterial membranes to improve this problem

Abstract

The invention discloses a preparation method of a foam type biomaterial film. The preparation method comprises the following steps: S1, preparation materials selection, wherein the preparation materials comprise a biological material, a liquid and a gas; S2, preparation of a biological material liquid: 1-2 g of a biological material and 100 ml of an HCL liquid are taken, mixed and stirred under the temperature of 4 DEG C until the mixture is stirred to be uniform to prepare the biological material liquid of different concentrations for later use; S3, neutralization of the biological material liquid: a sizeable dialysis bag is put into water for being boiled for one minute and then one end of the dialysis bag is sealed; and S4, preparation of biological material foam. The preparation methodprovided by the invention is more scientific and reasonable; the fluidity of the biological material adopted in the foam type biomaterial film is relatively high, and the biomaterial film has high adhesion; the biological material foam has very strong plasticity, and is capable of fully filling repair positions of any shape or any size; the biological material foam can control wound bleeding andprevent adhesion and scars from forming, thereby realizing tissue repair; and the foam type biomaterial film can be applied to residual cavity filling.
