Description
技术领域
本发明涉及垫片及其制造方法和使用该垫片的胶粘绷带。
背景技术
通常将由天然纤维例如棉和合成纤维例如粘胶纤维制成的、沿纵、横向切成四边形形状的纤维集合体或无纺布织物用作垫片,尤其是用作吸收体液和保护伤口的胶粘绷带的垫片。另外,通常使用将这样的织物用作垫片材料、并被塑料例如聚乙烯的膜或网覆盖、以防这样的垫片材料粘结伤口或刺激的垫片。对于覆盖方法,两个方向固定和四个方向固定是已知的方法。图1是形状已知的胶粘绷带的垫片的实施例,它使用沿纵、横向切成的长方形无纺织物作为垫片。
在这样的具有例如正方形或长方形形状的垫片中,当它用于胶粘绷带时,由于垫片的厚度,应力集中于胶粘绷带的背衬上的垫片四边处;而且会自边缘处出现泄漏,背衬也会从皮肤上剥离或剥落。在聚合物网覆盖垫片的情形下,当在两个方向固定垫片而不是四个方面时,在未固定的两个方向上,构成垫片的纤维会泄漏或凸出来,这样的外观不好。在固定四个方向的情形下,制造工艺变得复杂,成本高,生产率下降,因而通常采用的是固定聚合物网的部分边线。
发明内容
本发明涉及含有近似四边形的部分和连接于近似四边形部分两侧边的近似半圆形的部分的垫片,所述垫片的所有边线采用超声波方法密封。其中当L表示沿平行于侧轴方向上的近似四边形部分的长度、S表示沿平行于纵轴方向上的近似四边形部分的长度、R表示所述近似半圆形部分的半径时,满足下面的关系式:
L和S之间,0.5S≤L≤4S;
S和R之间,0.5S≤R<S;
具有这样形状的垫片可以提供使用时的舒适感,不降低吸收体液的性能,四边也没有纤维泄漏,而且有可能简化制造工艺,提高生产率,并降低残品率。
可以根据施用垫片的伤口的形状、范围、长度等,来合适地选择垫片的尺寸。然而,当L表示沿平行于侧轴方向上的近似四边形部分的长度、S表示沿平行于纵轴方向上的近似四边形部分的长度时,L和S应当满足下面关系式:0.5S≤L≤4S。当L不超过0.5S时,此范围不是优选的,因为使用胶粘绷带时,胶粘绷带的侧向方向的长度不能做得足够长;当L超过4S时,如果大量体液流出伤口,垫片太薄不能吸收体液,因此它也不是优选的范围。另外,当考虑本发明的垫片要覆盖伤口以吸收大量体液时,它最好是满足下面关系式:0.9S≤L≤1.45S。
在本发明的垫片中,上述R和S可以是如下关系:0.5S≤R<S。当R不超过0.5S时,所述近似半圆形部分的直径就变成比近似四边形部分的纵向长度小,垫片的周边曲线就难以是平滑的。当大于S,近似半圆形部分的圆弧太直,也不是优选的范围。在本发明的垫片中,如果要有效地吸收住渗出体液,优选的是满足下面关系式:0.55S≤R≤0.9S,尤其是0.6S≤R≤0.8S。为了使垫片的边线形状平滑,垫片的角优选是圆的。图2显示了S、L和R的之间关系。
本发明的垫片的整个边线,由例如超声波加热来密封。通过密封整个边线,可以几乎完全阻止纤维端头自垫片四边的泄漏。在超声波加热中,只有当超声穿透,才会产生热,产品的出成率和安全性得以改善。有可能实现高速率生产,从提高生产率和使设备微型化考虑,超声波加热也是优选的。为了进一步降低设备成本,也可以采用电-热-密封来代替超声波-热密封。
当如上所述密封整个边线时,密封的部分能够比未密封部分薄,此外,厚度可以自中央未密封部分向周边、进而向胶粘绷带的粘合层逐渐变化。由此如果未密封部分做得厚,可得到自未密封部分朝向周边平滑的厚度变化,也可以防止胶粘绷带的剥离。
垫片的材料没有特别的限制,只要材料具有合适的弹性和可吸收液体的性能,可以使用天然纤维、合成纤维的纤维集合体或无纺织物,其中无纺织物是优选的,因为这样可以控制住大的体积,增强吸收液体的能力。作为天然纤维,能够使用棉、丝光木棉,而合成纤维可以使用聚乙烯、聚丙烯、聚酯和粘胶纤维。合成纤维是优选的,因为它们可以热密封,易于加工,尤其是垫片材料优选包括两种以上的纤维,该纤维含有选自粘胶、聚乙烯、聚酯和聚丙烯中的一种或两种以上的材料。另外,还能够使用两种或三种以上的纤维的混合物。可以混入吸水性纤维例如吸水性聚酯、还有可吸水的聚合物粒子,以增强液体的吸收性能。当使用粘胶来增强吸收液体的性能时,粘胶的含量可以是30-60%,如果低于30%,不能获得混入粘胶的预期效果。当粘胶含量超过60%时,不能得到较佳的可热密封性。
在垫片的外表面,可以覆盖例如聚合物织物,无纺布织物或网或膜。优选的是聚合物网,这是由于其在热密封工艺中具有可操作性。用聚合物网覆盖垫片材料的外表面,会保留垫片的形状,阻止垫片材料纤维的散开,还可以防止垫片材料与伤口的直接接触,或阻止垫片固定到伤口上。用于聚合物网材料的聚合物没有特别限制,然而,优选的是:聚烯烃例如聚乙烯、聚丙烯、聚酯例如聚对苯二甲酸乙二酯和聚对苯二甲酸丁二酯、尼龙等。尤其优选的是聚乙烯,这是由于其具有可加工性、可自伤口的剥离性、安全性等。
当采用无纺织物作为垫片材料、聚合物网作为覆盖材料来制造本发明的垫片时,垫片和聚合物网的密封和裁切能够同时进行。同时实施这些工序,可以简化工艺,防止密封部分和裁切线之间的偏移,也可以防止形成不合规格的产品,提高产品的出成率。另外,从工作效率考虑,同时实施这些工序也是优选的。尤其优选的是同时采用超声波加热来实施密封和裁切,然而,工艺可以是:首先由超声波加热密封无纺织物和聚合物网,接着由超声波加热裁切密封部分的周边。另外也能够采用这样一种方法,在垫片表面上的许多点处,对无纺织物和聚合物网进行点密封,密封其周边,然后由超声波加热来裁切密封部分的边线。
本发明的垫片包括可以保护伤口、降低伤口引起的烦忧和促进愈合的所有的设置,该保护的伤口是例如手术伤口、外部伤口和由外部刺激引起的皮肤感染,降低伤口引起的烦忧是指通过吸收体液例如从伤口流出的血。垫片可以独立使用,还广泛地用于绷带、胶粘绷带、敷料、伤口敷料,尤其用于胶粘绷带的垫片。
本发明的垫片可提供使用时的舒适感,而不降低吸收液体的能力,没有纤维从其四边泄漏,而且有可能简化制造工艺,提高生产率,并降低残品率。尤其当用于胶粘绷带时,能够阻止垫片从其四角处剥离,和防止外部水的侵入。

具体实施方式
图2显示了本发明一个实施例的周边。近似四边形部分由被垫片周边的直线和垫片内的点线所包围成的长方形表示,半圆形部分由连接于近似四边形部分左、右两边的区域显示。直线的长度由L表示,点线的长度由S表示。半圆形部分的圆弧半径由R表示。在此实施例中,L/S的比例是1.5,R/S是0.7。图2由直线和圆弧组成,图3是图2中的垫片的实施例,其中四个角是圆形的,图4显示了L/S是1.0,R/S是0.7的实施例,图5显示了图4中实施例的四个角为圆形时的实施例。图6显示了图2中所示的本发明垫片用于一个胶粘绷带时的实施例。与图1所示的常规胶粘绷带相比,当施用此胶粘绷带时,它很难剥落,因为垫片周边的拐角处的角度小,在淋浴或洗涤时,胶粘绷带能够防止外部水的侵入。
图7显示了采用超声波加热,密封和裁切形状如图3所示的垫片周边的实施例的平面视图。密封部分(3)位于垫片的整个周边。图8显示了此实施例的正视图。未密封部分比已密封部分厚几倍。图9显示了图7中B-B截面的视图,图10为其侧视图。由超声波加热密封的垫片上看不到纤维的泄漏。
图11是使用如图7所示的垫片的胶粘绷带的平面视图,图12是其前视图。
图13是通过超声波加热实施本发明垫片周边的密封和裁切的机器示意图。无纺织物和聚合物网分别从上面送入,由支撑辊层压并在超声发生器的辐射头和辊之间通过。无纺织物和聚合物网由超声振荡器加热、密封、裁切,然后就制成了垫片。
也可以在支撑辊和超声波发生器的辊之间连接点密封设备,以便以合适的距离和分散状态实施垫片表面的点密封。
