The invention provides a double-cooperative cooling wound dressing, which includes a biologically active material layer and an infrared high-transparency support layer that are arranged in sequence, wherein the biologically active material layer is arranged close to the side of the wound surface, and has the function of infrared radiation heat dissipation, and the infrared high-transparency support The transmittance of the layer to infrared rays is greater than 90%, and the total reflectivity of the bioactive material layer and the infrared high-transmittance support layer to sunlight is greater than 95%; it is used to dissipate the heat from the wound surface in the form of infrared radiation heat dissipation through the bioactive material layer At the same time, by reflecting sunlight, it can synergistically alleviate the overheating of the wound surface under direct sunlight at high temperature. The invention designs the structure of the wound dressing, which can realize passive cooling, overcome the problem that the temperature of the wound increases due to light absorption, create an ideal micro-environment for the repair of the wound under high-temperature sunlight, and avoid the difficulty of the wound caused by overheating of the wound under the sunlight. Healing; the invention provides a new idea for the preparation of functional wound dressings, and has important research and economic value. |
