Embodiment Construction

[0038] like figure 1 As shown, the preparation process of the wound dressing is as follows: first, as in step S110, the first polyurethane elastic film is used as the base cloth, and the first polyurethane elastic film is subjected to surface modification treatment to obtain a hydrophobic first polyurethane elastic film; As in step S120, the end surface of the second polyurethane elastic film is curled and coated with an adhesive; then as in step S130, a hydrogel coating layer is applied on one end surface of the non-woven fabric layer, and crosslinked by ultraviolet light The way to polymerize the hydrogel and bond it to the non-woven fabric. Another example is step S140: using a crimping device to attach the second polyurethane elastic film to the other end surface of the hydrogel coating to form a composite layer; finally, as in step S150, slitting the curled composite layer cutting, and then performing line cutting and punching on the stripped strips to obtain the wound d...

Abstract

The invention discloses a preparation process of a wound dressing, which is characterized by comprising the steps of: with a first polyurethane elastic film as a base cloth, coating hydrogel on the first polyurethane elastic film; and then adhering a second polyurethane elastic film on the coating end face of the hydrogel by using a coiling device to form a composite layer body. The preparation process of the wound dressing can be used for preparing the wound dressing meeting the use requirements of multiple wounds, can also be used for preparing the wound dressing with the functions of keeping a wound healing environment, shortening healing time, resisting bacteria and reducing infection chances, is rapid, and accords with the industrial production requirements.

Description

technical field [0001] The invention belongs to the technical field of preparation of medical dressings, and in particular relates to a preparation process of a new type of wound dressing capable of maintaining the wound healing environment, shortening the healing time, antibacterial and reducing the chance of infection, which can make the wound dressing effectively conform to the physiological conditions of human tissue , to achieve the scientific management of trauma. Background technique [0002] According to scientific and statistical reports in recent years, the demand for trauma in the global market is increasing, especially surgical trauma. The number of wounds and lacerations caused by accidents is about 20 million per year, and the number of burns and scalds is about 10 million per year; ulcerative wounds caused by chronic diseases, diabetes, and aging population have exceeded 3 Tens of millions of visitors per year. [0003] Due to the demand for treatment and th...
