Description

本发明一般涉及吸收和（或）容纳月经液和其它人体流出液的妇女卫生保护用品的领域。更具体地说，本发明涉及一种提供外形的随意性和舒适性的阴唇间用的卫生垫。
设计用来吸收体液（包括月经）的常规的妇女卫生保护用品按功能设计可分为四类。第一类是卫生巾，穿戴在外部覆盖阴部区，主要设计用于大量行经。第二类是薄的裤衬，用于少量行经。第三类是棉塞，设计安置在阴道内部。第四类是阴唇间卫生垫，设计至少部分安置在使用人的小阴唇内。
在第一类中，卫生巾由于有一种薄的或厚的吸收部件而能够具有高的吸收能力。但是，在走路之类身体活动期间，使用人的大腿和阴部区的压力可以导致卫生巾移动离开原先保护外阴区的位置。在一个相对较短的时间后，卫生巾可能移动离开阴道口。使用人的运动，特别是诸如快速走路或跑步之类剧烈运动，也可能引起不舒服，如对敏感的外阴区域的摩擦和刺激所造成。
除了担心卫生巾的移动和使用人的不舒服以外，还存在被别人明显看出使用了卫生巾的担心。当对使用人的外衣进行观察时，某些厚的卫生巾具有隆起的外形。当穿上紧身衣服时（包括工装裤、健美服、游泳衣或类似的薄的或紧身的外衣），卫生巾可能非常明显。
在第二类中，开发的裤衬用于少量月经。某些裤衬具有与卫生巾相近的问题，虽然其形薄使它们比起厚实的卫生巾来较为轻柔，外形较不突出，而且通常较舒服些。但是，薄形裤衬在吸收能力的性能方面可能是一个弱点。
作为第三类妇女护理用品的棉塞被塞在阴道内以挡住体液。一些妇女从个人观点出发，认为棉塞在身体方面或心理方面是不能接受的。其次，一些棉塞不能够合适地防止泄漏，因为棉塞在阴道内的膨胀不能形成完全的密封。但是，没有棉塞在阴道内的此种径向膨胀和鼓涨，棉塞就不能用作可靠的卫生保护用品。
作为第四类妇女护理用品的阴唇间卫生垫，可以看作卫生巾和棉塞之间的混合用品。阴唇间卫生垫提供一个设计成设置在妇女小阴唇内的突出点或凸出部。当通过使用人的外衣观察时，阴唇间卫生垫可以形成最佳的外形轮廓，而且不存在如棉塞所要求的在阴道内可靠地膨胀的同样问题。但是，目前可以使用的阴唇间卫生垫，在使用人感到不舒服或由于泄漏到使用人外衣而失效之前，可以吸收的体液量很有限。
由Hirschman申请发布的美国专利Nos.3，726，277，3，983，873和4，175，561公开了几种阴唇间卫生垫（interlabial        hygienicpads），商品名称为“新颖贴合垫”（Fresh′n        Fit        padette）。这些垫设计成位于小阴唇之间，由于能够舒适地贴合在小阴唇之间的吸收体的量小，它们只具有容纳少量体液的容量。
现在以经开发了一种阴唇间卫生垫，它使用舒适，同时提供充分的保护。
简短地说，本发明涉及一种吸收和容纳月经液的阴唇间卫生垫。阴唇间卫生垫具有一个液体接收组件、一个容量组件和包含在这两个组件中的吸液纤维，液体接收组件适合于装入妇女的小阴唇区域，容量组件包含从接收组件一端延伸的吸收物料并适合于安置在小阴唇区域的外部。吸液纤维提供一些吸收能力，并且还能够将液体从接收组件载带到容量组件。本发明包括由纵向取向的吸液纤维形成的吸液纤维，装填在容量组件中的体密度大于接收组件中的体密度。阴唇间接收组件有一个安置在吸收剂上面的透液外罩，而容量组件有一个不透液体的隔罩，将体液容存在那里。在一个方面，容量组件适合于安装在位于或靠近妇女会阴区的位置上。阴唇间卫生垫可以具有一个扁平的扇形的容量组件，并可包含超级吸收物料。
本发明的一般目的是提供一种阴唇间卫生垫，以吸收并容纳月经液或其它人体渗出液，包括尿。本发明的更具体的目的是提供一种在身体方面和心理方面对使用人很舒服的阴唇间卫生垫。
本发明的另一个目的是提供一种能够吸收大量体液的阴唇间卫生垫。
本发明的又一个目的是提供一种阴唇间卫生垫，它能吸收大量的月经和其它人体渗出液，而同时在妇女护理用途中提供更好的使用舒适性。
本发明的第四个目的是提供一种阴唇间卫生垫，它能吸收大量的体液，而同时与通过使用人的外衣观察时只形成很薄的外形轮廓。
本发明的第五个目的是提供一种阴唇间卫生垫，它能吸收大量的体液，而同时提供更好的保护作用，防止通过使用人外衣泄漏。
对于熟悉本技术的专业人员来说，通过下述说明和附图，对本发明的其它目的和优点将会更加清楚。
图1是阴唇间卫生垫的平面图。
图2是图1所示阴唇间卫生垫的侧视图。
图3是阴唇间卫生垫用于妇女身体上的示意图。
图4是包括保护性侧部屏蔽的阴唇间卫生垫的透视图。
图5是图4所示阴唇间卫生垫的端部立视图。
现在参照图1和图2，图示一种包括接收组件20和容量组件30的阴唇间卫生垫10。
接收组件20包含松散安装的液体吸收剂/吸液纤维22并适合于安装在妇女的小阴唇区。我们相信，适合于本发明的液体吸收剂/吸液纤维22可以由能够吸收和渗吸人体流出液的任何吸收物料组成。合适纤维的例子包括（但不限于）聚丙烯纤维、聚酯纤维、粘胶纤维、棉纤维、木浆绒纤维，漂白的或未漂白的，或者是经过或未经过表面活性剂处理的这些纤维的混合物。
最好是，液体吸收剂/吸液纤维22沿纵向取向，以适合小阴唇区。接收组件20中的液体吸收剂/吸液纤维22可以由能透过月经液和其它人体渗出液的外罩24覆盖。一种合适的覆盖物料可以是纺粘的物料。
在接收组件20的外罩24里面，液体吸收剂/吸液纤维22在接收组件20和容量组件30之间产生液流连通，以便将液体从接收组件20载带到容量组件30。液体吸收剂/吸液纤维22最好由一种能够被润湿并渗吸月经或其它人体渗出液的物料组成。适合于作为液体吸收剂/吸液纤维22的经济纤维的例子为醋酸纤维束，例如在一个实施例中为三股截面或者是成多股截面的粘胶纤维。
在一种最佳实施例中，液体吸收剂/吸液纤维22被松散地装填在接收组件20的外罩中。接收组件20中的未压实的液体吸收剂/吸液纤维22最好沿纵向取向，并连续进入容量组件30，在该处纤维填得更紧密些，形成压实的吸液纤维32。这使得在不同组件20和30各自的未压实液体吸收剂/吸液纤维22和压实的吸液纤维32之间产生一个密度梯度。装填在容量组件30中纵向取向压实的吸液纤维32的体密度大于接收组件20中的液体吸收剂/吸液纤维22。密度梯度促使液体从接收组件20流向容量组件30。
容量组件30适合于佩带在妇女小阴唇区外部或远未接触小阴唇区的位置。容量组件30中的吸收剂物料可以是能够吸收人体排出物的任何吸收剂，如聚酯纤维、粘胶纤维、棉纤维、木浆绒纤维，漂白的或未漂白的，或者是经过或未经过表面活性剂处理的这些纤维的混合物。
容量组件30可以被制成包含高容量吸收剂或超级吸收剂34（SAM）。超级吸收剂可以是一种或多种能够吸收数倍于本身重量的月经或体液的物料。超级吸收剂34可以由熟悉本技术的专业人员所知道的超级吸收物料形成。
在一个方面，从接收组件20伸出的未压实的液体吸收剂/吸液纤维22进入到容量组件30的压实的吸液纤维32可以被看作为在接收组件20和容量组件30之间连通的通道，以便将液体从接收组件20载带到容量组件30。最好是，通道包括以不同体密度装填的沿纵向取向的吸液纤维，此体密度从未压实液体吸收剂/吸液纤维22到压实的吸湿纤维32是增大的。
压实的吸液纤维32将液体传递到容量组件30中包含的高容量吸收剂34。压实的吸液纤维32终止在或靠近容量组件30的远端，其位置适于使液体与捕集和保存月经液的高容量吸收物料34连通。如上所述，高容量吸收物料34可以是超级吸收剂。
一个渗透液体的外罩24围绕液体吸收剂/吸液纤维22和压实的吸液纤维32。一个不能渗透液体的隔罩36围住容量组件30中的高容量吸收剂34。
容量组件30包括能够围住整个容量组件的不渗透液体的隔罩36。不渗透液体的隔罩36可以是聚乙烯、聚丙烯或任何其它具有相同性能的材料的高分子薄膜，包括可以透气的薄膜。隔罩36的高分子薄膜可以与无纺物料结合，制成一个不渗透液体的像布似的外罩或隔罩。隔罩36将堵住体液流，使其不会流到使用人身体的外衣上。
容量组件30的构形可以是紧凑结构待吸收液体时膨胀，或者也可以是一开始就制成全尺寸的结构。容量组件30可以是扁平扇形，以便给使用人提供舒适。在一方面，容量组件30适于安装在或靠近妇女会阴区的位置。
较高密度的纤维32从较低密度的纤维22抽吸液体并将其保存在容量组件30中。较低密度纤维22的密度应在约0.03至0.14g/cm3的范围内。较低密度纤维22的最佳范围为约0.07至约0.11g/cm3，以提供所希望的整体性和容积。较当密度纤维32的密度应在约0.14至约0.3g/cm3的范围内。较高密度纤维32的最佳范围是约0.16至约0.22g/cm3之间，以提供所希望的容量而没有过分硬的感觉。
沿纵向取向的液体吸收剂/吸液纤维可以由其长度尺寸等于产品长度的四分之一到产品全长的纤维形成，其平均直径或标称直径为约1微米至1mm。纵向取向的压实的吸液纤维32可以具有等于产品长度的四分之一到全长的尺寸，其平均直径或标称直径为约1微米至1mm。
接收组件20以下述方式中任何一种连接到容量组件上：粘接，热接，超声结合，或允许组件间液体连通的任何方式。
并非企图限制到一种特定的尺寸，接收组件20的长度表示为L1，可以大约为50mm，加减约5mm。接收组件20的宽度表示为W1，可以大约为8mm，加减约1mm。同样，接收组件20的高度表示为H1，可以大约为15mm，加减约2mm。
并非企图限制到一种特定的尺寸，容量组件30的长度表示为L2，可以大约为45mm，加减约5mm。容量组件30的宽度表示为W2，可以大约为35mm（当充满时），加减约4mm。同样，接收组件30的高度表示为H2，可以大约为10mm（当充满时），加减约2mm。
容量组件30中体液的全部吸收和容纳量为至少约12克的数量级。这样的容量与原有的阴唇间卫生垫相比，属于高水平的液体容纳量。
参照图3，图示阴唇卫生垫10用于妇女身体上。接收组件20插在小阴唇40之间。小阴唇40是由大阴唇50的裂隙内两片合围的狭窄折皱层组织形成的。大阴唇是两块圆形的折皱层组织形成的，它们组成外阴的外部侧面边界。接收组件20的长度的中间覆盖在阴道口60上。如一个实施例中所示，容量组件30位于小阴唇40的后部，并延伸到会阴区70中。另一种方法是，阴唇间卫生垫10可以制成容量组件30向着小阴唇40的前部延伸，或者是容量组件30是从接收组件20直接向下延伸。阴唇间卫生垫10是通过大阴唇50及其周围人体组织对其施加的压力保持在位置上。
参照图4和图5，图示一种阴唇间卫生垫80具有一对保护性侧部屏蔽82和84。该保护性侧部屏蔽82和84固定在接收组件20的后部，以防止液体泄漏到使用人的外衣上。
因此，本发明提供一种能够吸收并容纳月经液或其它人体排出液的妇女个人保健护理产品或卫生防护用品，其方法是利用安置在小阴唇部位上的接收组件20挡住月经液的流动，同时利用安置在小阴唇外部或外边的部位上的容量组件30渗吸液体。该种妇女卫生防护用品的作用是将吸收的液体移动到远离接收组件20所在的阴唇间部位的容量组件30中，并能较先有技术的阴唇间卫生防护用品吸收更多的液体。
虽然本发明的说明只用了几个实施例，但可以理解，根据以上说明，对于熟悉该技术的专业人员来说，显然可以有许多替代、变型和变化。因此，本发明打算包括属于所附权利要求书的宗旨和范围的所有这些替代、变型和变化。
