Abstract
本发明属卫生材料。以醋酸纤维代替天然棉花用于临床，不仅可取代药棉、脱脂棉、脱脂纱布、绷带，且具有不粘创面、易揭、无痛的特点，促进创面愈合，利用组织再生之功效。以再生人造纤维-醋酸纤维代替纯棉或以纯棉为主的复合敷料，不仅节省了资源，且免除了纯棉脱脂、敷料复合之工序。
Description
本发明涉及一种新的卫生材料，特别是以二醋酸纤维制成的医用不粘敷料。
传统的包扎创伤所用的敷料大多为纯棉制品。这不仅要消耗大量优质棉花，而且为使这些敷料吸收伤口水份及分泌物，均需作脱脂处理。通常的作法是将棉花或其它棉制敷料经碱液高温蒸煮、漂洗、干燥脱去棉脂而得到脱脂棉或脱脂纱布及绷带等敷料。在临床中所使用的这些棉制敷料，在给伤员创面包扎时，伤口创面的血浆或分泌物渗出液被敷料吸收，并在短时间内会干固硬化，使敷料和新生的肉芽粘连在一起，成为僵硬的板状物。这些板状物不仅压迫创面影响组织生长，尤其是在更换敷料时，更要破坏正在痊愈的伤口产生第二次创伤、给伤员增加了新的痛苦。
为了避免伤口与敷料粘连，一种复合敷料业已问世。如英国TJ·Smith and Nephew公司生产的商标为Airstrip的敷料。这是一种以脱脂棉复合某种半渗透塑料薄膜而制成的敷料。将半渗透膜直接覆盖伤口，外层是脱脂棉，伤口渗出液经半渗透膜被脱脂棉吸收，而半渗透膜则起到防止敷料与创面粘连的作用。
综上所述，无论是传统的纯棉敷料或复合敷料，都要消耗大量棉花，而且制成复合敷料加工工艺复杂，成本较高。
本发明的目的在于克服上述已有敷料存在的缺点，制成一种既不使用纯棉又不与创面粘连的医用敷料。
敷料是由纤维经过加工而制成，本发明的目的是通过选择适当的纤维来实现的。纤维分为天然纤维与化学纤维，而化学纤维又分为合成纤维与人造再生纤维。一般来说合成纤维吸湿率较低，不能满足作为敷料吸收分泌物及渗出液的需要。再生纤维是以含天然纤维素的木材、芦苇、棉短绒、甘蔗渣、棉秆、小麦秆等为原料制得浆粕经适当的化学处理而得到的人造纤维，其主要品种有粘胶纤维、醋酸纤维和铜氨纤维。这些纤维与棉相比，吸湿率不相上下，甚至高于棉，作为敷料可满足吸湿要求，经试验筛选，醋酸纤维具有与创面不粘的特性。
本发明所采用的醋酸纤维是由浆粕与醋酸、醋酐、在少量硫酸存在下酯化后所得到的二醋酸纤维素，为白色柔软、蓬松的丝状物，无味无毒、不刺激皮肤。其吸湿率或回潮率在20℃，65％相对湿度下为6-7％，与棉接近(棉为7％)。这种纤维可直接代替脱脂棉也可将其纺丝加工成所需规格的纱布。例如：21支、32支、42支或80支纱规格的平纹纱布，这种纱布可代替脱脂纱布包扎创面，将醋酸纤维不加粘合剂经机械络合、或抄合或其它方式制得各种适宜规格的无纺布。如规格为50克～80克/m2这些都可做为纸型纱布代替脱脂纱布用于创面敷料，也可按一定要求织成弹性绷带。如宽度为5cm～50cm。
以上用醋酸纤维制成的敷料称为医用不粘敷料，质检应符合卫生材料有关标准，使用方法与纯棉敷料相同。不粘纱布和纸型纱布(即无纺布)经北京市积水潭医院烧伤科对102例次烧伤创面临床应用，其中烧伤面积最大者为95％，临床观察认为，该纱布对深浅烧伤新鲜创面用后易揭不痛、肉芽创面不粘、易揭、不痛。北京协和医院皮肤科对114块创面临床应用，其中化脓性创面95块，浆液性创面19块，试验结果为：
1、纸型不粘纱布49个创面有46个与纱布不粘、易揭，3个有轻度粘连，其中尚有3例在纱布下留有一些隐性分泌物。
2、不粘纱布65个化脓性创面用不粘纱布换药均不粘、易揭、肉芽生长良好、无不适感。
本发明的医用不粘敷料，适用于灼伤、溃疡、脓肿和任何外伤的伤口。与现有的纯棉敷料或复合敷料相比，以再生纤维代替天然棉花，不仅可充分利用资源，而且避免了纯棉脱脂及敷料复合的繁琐工艺，同时又具有对伤口易揭、不粘、无痛之优点，有利创面愈合，促进组织再生之功效。
不粘纱布及弹性绷带采用常规方法，传统工艺、纺纱、织布制成产品。
纸型不粘纱布(无纺布)采用已有的机械热合或抄合(不加粘合剂)工艺制得成品。
为了加强本发明的不粘纱布的抗拉强度，减少织布期间出现的断头率，亦可将醋酸纤维材料与市售尼布纤维，按常规方法纺成皮芯型复合结构的纤维。
实施例1
以二醋酸纤维素为原料，按常规工艺纺纱、织布。可根据需要织成下列规格的医用不粘纱布。
实施例2
