Embodiment 1

[0030] Embodiment 1: a kind of manufacture method of antibacterial, hemostatic dressing, its flow chart is as figure 2 , image 3 shown, including the following steps:

[0031] (1) Preparation of antibacterial film layer 1: Take 15g of antibacterial material 11 and place it on the first release paper 13 that is conveyed by the conveyor belt 12; a release paper 15 is provided in the first mold 14, and the first mold 14 is pressed down. A mold 14, the antibacterial material 11 is pressed into a square of 10cm × 10cm; the antibacterial material 11 after pressing is dried to a dryness of 50% under the condition of 60°C to form an antibacterial film layer 1; the antibacterial material 11 is the mixture of hexyl alcohol and polyvinyl alcohol mixed with a mass ratio of 1:10;

[0032] (2) Prepare the hemostatic film layer 2: take 15g of the hemostatic material 21 and place it on the release paper 24 that is conveyed by the conveyor belt 22; a release paper is provided in the second...

Embodiment 2

[0035] Embodiment 2: The difference from Example 1 is that the antibacterial material 11 is a mixture of sorbitol and sodium alginate mixed at a mass ratio of 1:10; the preset antibacterial material 11 and hemostatic material 21 The amount is 10g.

Embodiment 3

[0036] Embodiment 3: The difference from Example 1 is that the amount of antibacterial material 11 and hemostatic material 21 taken is 30 g, and the shape of the pressed antibacterial film layer 1 and hemostatic film layer 2 is a square of 20 cm × 20 cm; In step (3), two layers of antibacterial film layers and two layers of hemostatic film layers were respectively selected and stacked alternately and then pressed.

[0037] Antibacterial, hemostatic dressing made by embodiment 3, its structure is as figure 2 As shown, the first release paper 3, the hemostatic film layer 2, the antibacterial film layer 1, the hemostatic film layer 2, the antibacterial film layer 1, and the second release paper 4 are sequentially included from bottom to top.

[0038] Unless otherwise specified, the instruments and equipment involved in the above examples are conventional instruments and equipment; the involved industrial raw materials are commercially available conventional industrial raw materi...

Abstract

The invention discloses a method for preparing an antibacterial and styptic dressing, and aims to solve technical problems that the conventional antibacterial and styptic dressings are not easy to mix or not good in antibacterial and styptic effect after mixing. The method for preparing the antibacterial and styptic dressing is to prepare an antibacterial film, to prepare a styptic film, and to correspondingly laminate and press the antibacterial film and the styptic film. The antibacterial and styptic dressing prepared by the abovementioned method has a function of quick bleeding stop and antisepsis and anti-inflammation, is beneficial for wound recovery, can be widely applied to clinic treatment, and is convenient for quick and effective treatment of wound. The method for preparing the antibacterial and styptic dressing is simple to operate, high in production efficiency, and available for integrated product of antibacterial and styptic dressings.

Description

technical field [0001] The invention relates to the technical field of production and manufacture of medical antibacterial and hemostatic materials, in particular to a method for manufacturing an antibacterial and hemostatic dressing. Background technique [0002] During surgical operations or when the human body is subjected to external trauma, it is often necessary to use medical dressings for local wound hemostasis. Hemostasis is an important part of clinical treatment, and effective hemostasis is a necessary guarantee for the safety of patients' lives. In addition, for skin injuries caused by burns, wounds and skin ulcers, it is usually necessary to use medical dressings to protect the wound, prevent wound infection, and promote wound healing. Therefore, the preparation of a widely applicable medical dressing with both antibacterial and hemostatic functions will be beneficial to rapid hemostasis and promote wound healing during treatment, which is of great significance a...
