Embodiment 1

[0023] A preparation method for medical bandage, comprising the steps of:

[0024] (1) Preparation of bacterial cellulose composite membrane:

[0025] a. Put the bacterial cellulose membrane into the sodium hydroxide solution and soak it for 40 minutes, take it out and rinse it with deionized water after completion, and then set it aside;

[0026] b. Put the bacterial cellulose film processed in operation a into the pulverizer, stir and pulverize it at high speed continuously for 25 minutes to obtain pulverized material for subsequent use;

[0027] c. Put the pulverized product obtained in operation b into the reactor, then add a mixed solution of 7 times the total mass of the pulverized product into the reactor, and then heat to keep the temperature in the reactor at 60°C and the pressure at 0.4MPa, continuously After ultrasonic treatment for 50 minutes, suction filtration was carried out to form a film, and finally it was freeze-dried to obtain a bacterial cellulose composi...

Embodiment 2

[0039] A preparation method for medical bandage, comprising the steps of:

[0040] (1) Preparation of bacterial cellulose composite membrane:

[0041] a. Put the bacterial cellulose membrane into the sodium hydroxide solution and soak it for 43 minutes. After completion, take it out and rinse it with deionized water for later use;

[0042] b. Put the bacterial cellulose film processed in operation a into the pulverizer, stir and pulverize it at a high speed continuously for 28 minutes to obtain pulverized material for subsequent use;

[0043] c. Put the pulverized material obtained in operation b into the reactor, then add a mixed solution of 9 times the total mass of the pulverized material into the reactor, and then heat to keep the temperature in the reactor at 63°C and the pressure at 0.45MPa. After ultrasonic treatment for 52 minutes, suction filtration was carried out to form a film, and finally it was freeze-dried to obtain a bacterial cellulose composite film for late...

Embodiment 3

[0055] A preparation method for medical bandage, comprising the steps of:

[0056] (1) Preparation of bacterial cellulose composite membrane:

[0057] a. Put the bacterial cellulose membrane into the sodium hydroxide solution and soak it for 45 minutes. After completion, take it out and rinse it with deionized water for later use;

[0058] b. Put the bacterial cellulose film processed in operation a into the pulverizer, stir and pulverize it at a high speed continuously for 30 minutes, and then get the pulverized thing for later use;

[0059] c. Put the pulverized material obtained in operation b into the reactor, then add a mixed solution of 10 times the total mass of the pulverized material into the reactor, and then heat to keep the temperature in the reactor at 65°C and the pressure at 0.5MPa, continuously After ultrasonic treatment for 55 minutes, suction filtration was carried out to form a film, and finally it was freeze-dried to obtain a bacterial cellulose composite ...

Description

technical field [0001] The invention belongs to the technical field of medical materials, and in particular relates to a preparation method of a medical bandage. Background technique [0002] Bandage is a necessity in medical treatment and daily life, and it plays the role of bandaging to stop bleeding, surrounding and fixing. The initial bandages were only made of cotton fibers, which had no special effect, and the overall mechanical strength was not high, and there were problems such as excessive dosage during use. With the development of technology and the needs of patients, bandages are developing in the direction of multi-function and improving patient comfort. Contents of the invention [0003] The object of the present invention is to provide a kind of preparation method of medical bandage aiming at the existing problems. [0004] The present invention is achieved through the following technical solutions: [0005] A preparation method for medical bandage, compri...
