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。 The present invention relates to a novel sanitary materials. Nonstick particular in medical dressing made of cellulose diacetate.

传统的包扎创伤所用的敷料大多为纯棉制品。 Traditional wound dressings dressings used mostly cotton products. 这不仅要消耗大量优质棉花,而且为使这些敝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髙退蒸煮、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吶组织生长,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.给伤员堆加了新的痛苦。 This not only consumes a large amount of high-quality cotton, but also for these spacious feed and water absorbing wound secretions, required for the degreasing treatment, it is common practice to other cotton or cotton applicator was back Gao alkaline cooking, washing, drying off wool fat to obtain cotton gauze and bandages or other dressings, these cotton dressings used in the clinic, when the wound dressing to the wounded, a wound bed discharge plasma or exudate absorbed by the dressing, and in a short time dryness will harden within the nascent granulation blocking the dressing together and become rigid the plate. these plates wound was not oppressed Movies na tissue growth, especially during dressing changes, but also to destroy the healing wound is produced the second trauma. wounded stack up to a new pain.

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。 In order to avoid the wound dressing adhesion, a composite dressing has come out, such as trademarks UK TJ • Smith and Nephew produced for the Airstrip dressing. 这是一种以脱脂棉复合某种半渗进塑料薄膜而制成的敷料.将半滲透膜直接覆盖伤口,外层是脱脂拥.伤口渗出液烃半滲透膜被脱脂棉吸收,而半渗透膜则起到防止敷料与创面粘连的作用。 This is a semi-dressing in some cotton infiltrated composite film made of plastic. The semi-permeable membrane covering the wound directly, defatted outer layer is owned Wound exudate is absorbed hydrocarbon cotton semipermeable membrane, the semi-permeable membrane play a role in preventing the adhesion of the dressing and the wound.

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。 In summary, both the traditional cotton composite dressing or dressing must consume a large amount of cotton. Further a composite dressing process complex and costly.

本发明的目的在干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。 The present invention overcomes the disadvantages of dry dressings have been described above, neither to prepare a medical dressing with cotton wound without adhesion.

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雄来实现的。 Dressing is made of processed fiber, object of the present invention is by selecting an appropriate fiber male achieved. 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堆。 Chemical fibers and natural fibers into fiber, chemical fiber and synthetic fibers and is divided into an artificial fiber regeneration reactor. 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滄出液的需要,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轻适当的化学处理而得到的人造纤堆.其主要品种有牯胶纤维、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。 General synthetic low moisture absorption rate, can not satisfy the need for absorbent dressing as a fluid secretions and Tsang, regenerated natural cellulose-containing fiber is wood, reed, cotton linters, bagasse, cotton stalk, wheat straw, etc. materials obtained chemically treated pulp suitable light obtained rayon stack. the main varieties revolves gum, cellulose acetate and cuprammonium fibers, compared with cotton fibers, moisture absorption rate comparable to, or even higher than cotton as an absorbent dressing may meet the requirements, the screening test, cellulose acetate having a non-stick characteristics of the wound.

本发明所采用的醋酸纤堆是由浆柏与醋酸、醋酐、在少量硫酸存在下酯化后所得到的二醋酸纤堆素.为白色柔软、蓬松的丝状物,无味无毒、不刺激皮肤。 The cellulose acetate used in the present invention is a slurry reactor and Bo acetic acid, acetic anhydride, in the presence of small amounts of sulfuric acid after the esterification of the resulting fiber stack prime diacetate. White soft, fluffy filaments, odorless, non-toxic, do not irritate the skin. 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%)。 Its moisture absorption or moisture regain at 20 ℃, 65% relative humidity of 6-7%, with nearly cotton (cotton 7%). 这种纤维可直接代替脱脂棉也可将其纺丝加工戍所需规祜的纱布。 Such fibers can also be a direct replacement for cotton gauze desired gauge of the spinning process Shu Hu. 例如:21支、32支、42支或扣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。 For example: 21, 32, 42 or debit yarn size plain gauze, which can replace the gauze bandage gauze wound, the acetate complexed mechanically without adhesive, bonding or otherwise copied or prepared suitable non-woven fabrics of various specifications. 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。 The specifications for the 50 grams to 80 grams / m2 as the paper size gauze of which may be used in place of gauze wound dressings. 也可按一定要求织成弹性绷带。 It must also be woven in claim elastic bandage. 如宽度为5 cm ~50cm. The width of 5 cm 50cm ~.

以上用醋酸纤维制成的叛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)轻北京市积水潭医院烧伤科对102例次烧伤创面临床应用. Betray the above material made of cellulose acetate non-stick called medical dressings, sanitary materials should meet the quality standards, using the same method as cotton dressing. Non-stick gauze and the gauze matrix (i.e., a nonwoven fabric) light Jishuitan Hospital, Beijing clinical application of burn wounds in 102 cases of burns.

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,其中化肽性创面95块,浆液性创面19 块,试验结果为: The largest of which burn area of ​​95%. Clinical believe that the gauze of depth burn wounds fresh after use is not easy to expose the pain, wound granulation non-stick, easy to expose, not pain. Wound clinical application of Beijing Union Medical College Hospital Department of Dermatology of 114, wherein the peptide wound 95, serous wound 19, the test results:

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. 1, paper type non-stick gauze 49 and 46 wound with a gauze nonstick, easy to expose, mild adhesions 3, wherein there are three cases to leave some hidden secretions in gauze.

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。 2, non-stick gauze 65 purulent wounds with non-stick gauze dressing are non-stick, easy to expose, the growth of granulation good, no discomfort.

本发明的医用不粘敷料,适用子灼伤、溃疡、 The medical dressing of the present invention, non-stick, applicable sub burns, ulcers,

脓肿和任何外伤的伤口。 Any trauma wounds and abscesses. 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。 Compared with the conventional composite cotton dressing or dressings, to replace the natural cotton fibers regenerated, not only make full use of resources and to avoid the degreasing and cotton composite dressing cumbersome process. While having easy to expose the wound, non-stick, the advantage painless. advantageously wound healing, tissue regeneration promoting effect.
