现有对于伤口的处理，通常都是先清洁和消毒伤口之后，涂抹药膏，以纱布或类似材料包覆黏贴，等待伤口自行愈合后，再取开纱布等外部包覆固定材料。The existing wound treatment usually involves cleaning and sterilizing the wound first, then applying ointment, wrapping it with gauze or similar materials, and waiting for the wound to heal by itself, and then removing the gauze and other external covering and fixing materials.
这方式对一般小型伤口并没有太大问题，但对大面积伤口或因体质问题较难痊愈的伤员(例如糖尿病患者)而言，伤口的复原时间长，且要多次换药，非常辛苦，而在换药取下纱布时，常会因纱布等包覆物与伤口的组织液沾黏结合，使伤口受到拉力而发生再次撕裂的情况，导致伤口再次受损，痊愈的时间就更长。较进步的方式是使用人工皮肤的贴覆，但其改善的效果仍极有限，且无助于伤口的愈合。This method is not a big problem for ordinary small wounds, but for large wounds or wounded patients who are difficult to heal due to physical problems (such as diabetic patients), the recovery time of the wound is long, and the dressing needs to be changed many times, which is very laborious. However, when the dressing is changed and the gauze is removed, the wrapping such as the gauze is often combined with the tissue fluid of the wound, causing the wound to be pulled and torn again, causing the wound to be damaged again and taking longer to heal. A more advanced method is to use artificial skin covering, but its improvement effect is still extremely limited, and it does not help wound healing.

A non-stick base material including but not limited to fibers, yarns and fabrics, the second structure is a nano-gold sputtering layer, which is combined with one side of the base material, and the third structure is a blood-sucking cotton sheet, combined with the other side of the substrate.
本发明的使用方式为以纳米金溅镀层朝向伤口，通过纳米金具有的活化细胞，帮助血管增生的效果，可助益伤口的复原，而中间基材通过其不沾黏的特性，配合另一侧吸血棉片的组合，可顺利吸附组织液于棉片，避免伤口沾黏，便于敷材与伤口分离，达到俾益伤口愈合的功效。The use method of the present invention is to use the nano-gold sputtering layer to face the wound, through the effect of activating cells of the nano-gold to help the blood vessels to proliferate, which can help the recovery of the wound, and the intermediate base material, through its non-stick properties, cooperates with another The combination of the side blood-sucking cotton pads can smoothly absorb tissue fluid on the cotton pads, prevent the wound from sticking, and facilitate the separation of the dressing material from the wound to achieve the effect of benefiting wound healing.
