具体实施方式 Detailed ways

配制带正电荷的抗菌生物制剂和由乳化硅油、阳离子表面活性剂制成的防粘剂。 Antibacterial formulation of biological agents and positively charged by the silicone emulsion, the release agent made cationic surfactant.

抗菌防粘层:与皮肤接触的纱布层,将脱脂纱布经抗菌生物制剂浸泡10~20分钟,压辊除去水份,并经80℃~130℃高温烘干5~20分钟,利用特制的防粘剂对纱布进行降低表面张力处理,阳离子基团在纱布表面形成正电场,当伤口细菌接触到纱布表面时,带负电荷的细菌则被吸引形成共价键结构,进而破坏细菌的细胞壁,使细菌的内容物外泄致死,同时不断吸收创面的微生物及组织残屑,促进坏死组织软化和分离,迅速杀灭细菌,由于防粘剂具有网状透气性,将其处理于纱布表面后,高分子基团形成纵向排列,改变了纱布表面性能,并在其上形成了一层透气薄膜,使其粘力降低,达到与伤口不粘的目的,其易揭力小于0.3N。 Antibacterial release layer: skin layer in contact with the gauze, the gauze soaked in antibacterial biologic 10 to 20 minutes, the pressure roller to remove water, and dried 80 ℃ ~ 130 ℃ drying temperature 5 to 20 minutes, use a special anti gauze agent for reducing the surface tension of the treatment, a cationic group to form a positive electric field on the surface of the gauze, when the surface of the gauze contact the wound bacteria, the bacteria were attracted to the negatively charged form a covalent bond structure, thereby destroying the bacterial cell wall, so that lethal bacterial content leakage, while continuing to absorb wound microorganisms and tissue debris, necrotic tissue to promote softening and separated rapidly kill bacteria, since the release agent has a net permeability, which was treated at the gauze surface, high molecular group is formed vertically arranged, changing the surface properties of gauze, and a layer of breathable film is formed thereon, so as to reduce tack, non-stick wound with the purpose of its easy to expose force of less than 0.3N.

亲水层:采用经过环氧乙烷消毒的无萤亲水无纺布层,在伤口渗出液过多时,由于其特有的亲水功能迅速将其过滤的液体传递至吸收层。 Hydrophilic layer: The hydrophilic nonwoven fabric layer is subjected to no firefly ethylene oxide sterilization, too much wound exudate, hydrophilic because of its unique features filtered quickly transferred to the liquid absorbing layer.

吸收层:采用吸液量为自重100倍的高分子吸液材料丙烯酸钠聚合物,大量水份被亲水层送至高分子的透气空间,吸液后的高分子迅速膨胀成球状,并形成众多三角形空间,保持良好的通透性,使创面得到氧气和二氧化碳的交换,平衡细胞的创面环境。 Absorbing layer: the liquid absorbent in an amount of 100 times the weight of the polymer material liquid absorbent sodium acrylate polymer, a large amount of water is supplied to the space breathable hydrophilic polymer layer, the liquid-absorbent polymer after rapid expansion into a ball, and forming a plurality of triangular space, maintain good permeability, so that the wounds give exchange oxygen and carbon dioxide, balanced wound environment of the cell. 吸液后的高分子材料又缓慢释放无菌的水份,对创口起着平衡温润的调节作用。 After the liquid-absorbent polymer material and the slow release of sterile water, it acts as a counterbalance to the wound moist regulation.

辅助层:具有柔软、可塑和弹性的无纺棉层,使敷料与伤口吻合舒适。 Auxiliary layers: a soft, elastic plastic and non-woven cotton layer, so that a comfortable fit with the wound dressing.

疏水层:具有透气而不透水的疏水无纺布层,防止伤口渗出液渗出,确保衣物、卧具洁净无污染。 Hydrophobic layer: a hydrophobic nonwoven fabric layer having air-permeable and water-impermeable, to prevent the oozing wound exudate, ensuring clothing, bedding clean and pollution-free.

将五层材料根据规格要求进行裁剪、缝纫,则制成了具有抗菌防粘、高吸湿性、通透性、止血、镇痛,多层结构的医用敷料。 The five layer material is cut according to specifications, sewing is made having antibacterial release, high moisture absorption, permeability, bleeding, pain, medical dressings multilayer structure.
