Embodiment 1
[0032] This embodiment provides a method for preparing a soft tissue repair collagen film, comprising the following steps:
[0033] (1) Add type I collagen to an acetic acid solution with a concentration of 0.2% (v / v) to prepare a collagen-acetic acid swelling solution, wherein the concentration of type I collagen is 0.3% (w / v);
[0034] (2) Add chondroitin sulfate sodium to the collagen-acetic acid swelling solution, and stir evenly to obtain a collagen-chondroitin sulfate sodium slurry with a pH of 2.0, wherein the concentration of chondroitin sulfate sodium is 2% (w / v);
[0035] (3) Defoaming the collagen-chondroitin sulfate sodium slurry, then pouring it into a stainless steel freeze-drying tray, and placing it in a vacuum freeze dryer for the first vacuum freeze-drying; Machine pressed into a collagen basement membrane with a thickness of 0.1 mm;
[0036] (4) Pour the collagen-chondroitin sulfate sodium slurry between the two layers of the collagen base film, and use a...
Embodiment 2
[0039] This embodiment provides a method for preparing a soft tissue repair collagen film, comprising the following steps:
[0040] (1) Add type I collagen to an acetic acid solution with a concentration of 0.6% (v / v) to prepare a collagen-acetic acid swelling solution, wherein the concentration of type I collagen is 1.0% (w / v);
[0041] (2) Add chondroitin sulfate sodium to the collagen-acetic acid swelling solution, and stir evenly to obtain a collagen-chondroitin sulfate sodium slurry with a pH of 4.0, wherein the concentration of chondroitin sulfate sodium is 10% (w / v);
[0042] (3) Defoaming the collagen-chondroitin sulfate sodium slurry, then pouring it into a stainless steel freeze-drying tray, and placing it in a vacuum freeze dryer for the first vacuum freeze-drying; Machine pressed into a collagen basement membrane with a thickness of 0.5 mm;
[0043] (4) Pour the collagen-chondroitin sulfate sodium slurry between the two layers of the collagen base film, and use ...
Embodiment 3
[0046] This embodiment provides a method for preparing a soft tissue repair collagen film, comprising the following steps:
[0047] (1) Add type I collagen to an acetic acid solution with a concentration of 0.4% (v / v) to prepare a collagen-acetic acid swelling solution, wherein the concentration of type I collagen is 0.6% (w / v);
[0048] (2) Add chondroitin sulfate sodium to the collagen-acetic acid swelling solution, and stir evenly to obtain a collagen-chondroitin sulfate sodium slurry with a pH of 3.0, wherein the concentration of chondroitin sulfate sodium is 6% (w / v);
[0049] (3) Defoaming the collagen-chondroitin sulfate sodium slurry, then pouring it into a stainless steel freeze-drying tray, and placing it in a vacuum freeze dryer for the first vacuum freeze-drying; Machine pressed into a collagen basement membrane with a thickness of 0.3mm;
[0050] (4) Pour the collagen-chondroitin sulfate sodium slurry between the two layers of the collagen base film, and use a ...
