Description

安装垫
技术领域
本发明涉及一种包括粘合层的安装垫，该粘合层具有可移除的释放衬垫，以用在应用于患者皮肤上的设备(特别是输注设备)中。本发明还涉及一种包括安装垫的插管设备，该安装垫包括粘合层，该安装垫设有当输注套件应用于患者时可以自动地从安装垫移除的释放衬垫。此外，本发明涉及一种用于从安装垫移除释放衬垫的方法。另外，本发明涉及这样的安装垫的使用。
背景技术
US5384174A描述了一种用在皮肤上的粘合垫，所述粘合垫包括释放衬垫，该释放衬垫在垫应用在皮肤上之前被移除。释放衬垫可以是一个单个的块或具有划线或孔，使得释放衬垫被分成两个或多个段，从而释放衬垫可以成两个或更多块地从粘合设备移除。
EP0239244A1描述了一种用于流体向患者的皮下输送的注射设备，该注射设备具有包括背衬层、粘合层和可移除释放衬垫的粘合片。释放衬垫包括径向划线，该径向划线在释放衬垫的外周开始并在释放衬垫的中心孔的外周边界终止。释放衬垫在输注设备应用于患者之前被手动地整块移除。
WO00/44324A1描述了一种被可移除的释放纸覆盖的粘合垫，该释放纸具有一个或多个预切线或预划线，预切划线从释放纸的外周向内朝向释放纸的中心成直线延伸。粘合垫和可移除的释放纸可以具有容纳气门(stoma)的孔。
上面提到类型的产品具有一个风险，即在释放衬垫的移除过程中，粘合层会被使用者的意外接触污染。此外，具有减小其粘合到皮肤上的能力的风险。此外，对于已知的产品，在不撕开衬垫材料的前提下移除所有的释放衬垫也是困难的，特别是在释放衬垫为整块的情况下。此外，所需的拉力必须均匀或平稳，以便在拉动的过程中不破坏释放衬垫，由此不会在粘合表面上留下释放衬垫的残余物。
国际申请WO04/087240A1教导了一种用于放置在使用者的皮肤上的注射设备，并且例如胰岛素的医疗流体从该注射设备通过插管被注射到使用者身体内，作为注射设备包括皮下输注套件。输注设备可以借助于粘合垫粘合到使用者的皮肤上，该粘合垫被连接到输注设备的下表面，并且其粘合面朝向使用者的皮肤。在穿过皮肤并随后激活注射设备中的装置时，例如胰岛素的医疗流体的注射开始执行。覆盖粘合垫的释放衬垫具有一条划线，该划线将释放衬垫形成为单个螺旋形式的条。
将释放衬垫划成一个长的窄条提供了均匀的拉力，并且移除螺旋形的释放衬垫需要小的力，因为只需要克服由使用者撕成块的条之间的粘合力。但是，将释放衬垫划成单个条(例如螺旋的形式)意味着条以及拉动长度在整个释放衬垫从粘合垫移除之前的释放衬垫移除过程中会变得相对较长。
本发明的目标是消除上面提到的问题，并提供一种替换的安装垫，其可以单独地使用或者与输注设备结合使用，所述安装垫具有可容易地移除的释放衬垫，其可以在手的单独的向上直线运动下被移除，从而减小使用者错误地操作产品的风险。此外，一个目标是使用很小的力移除释放衬垫，同时在释放衬垫的移除过程中减小拉动长度，以获得更直的和向上的手的运动。
此外，本发明的一个目标是提供一种快速地和容易地应用于患者的输注设备。
本发明的另一目标是提供一种在不污染或损坏安装垫的粘合效果的前提下从安装垫移除释放衬垫的简单方法。
发明内容
本发明涉及一种包括粘合层的安装垫，所述层具有可移除的释放衬垫，所述释放衬垫被分成至少两个部件，其中，释放衬垫的至少两个所述部件中的每个都具有一条或多条划线，由此将释放衬垫的每个部件形成为条。
释放衬垫的每个部件的一端具有用于将所述一端固定到相对的定位表面上的装置。所述装置可以例如是一个表面，该表面具有使其适于与被放置在相对的定位表面上的粘合剂相粘合的特征，或者所述装置可以例如是能够将释放衬垫固定到相对的定位表面上的机械类型装置。
在第二方面，本发明涉及一种用于皮下引入插管的插管设备，该插管设备包括具有上面板和下面板的壳体、连接到下面板的插管、以及与下面板连接布置并用于将插管设备固定到皮肤上的安装垫；所述安装垫包括粘合层，并具有可移除的释放衬垫，所述释放衬垫被分成至少两个部件，并且释放衬垫的至少两个部件中的每个都具有一条或多条划线，由此将释放衬垫的每个部件形成为条。
本发明使得借助于单个直线向上的拉力将释放衬垫撕成两个或更多个窄条成为可能，从而在移除释放衬垫需要小的力的情况下，仍然保持均匀的拉力。此外，当释放衬垫被分成两个或更多个条时，释放衬垫的拉动长度减小了，同时该释放衬垫借助于单个直线向上的拉力被移除。
此外，操作是容易的，并且可以避免释放衬垫的撕裂。该操作将以与没有注射设备时使用安装垫的情况相同的方式发生。
在第三方面，本发明涉及一种从安装垫移除释放衬垫的方法，该方法包括将释放衬垫的每个部件的点保持在安装垫的外周中、通过以单个直线拉力拉动来移除释放衬垫。
本发明的方法使得以手的单个向上直线运动移除释放衬垫成为可能，从而减小使用者错误地操作产品的风险。此外，本发明的方法使得可以使用很小的力移除释放衬垫，同时在释放衬垫的移除过程中减小拉动长度，由此获得手的更直的向上运动。另外，本发明的方法减小了粘合层的意外接触的风险，从而减小了粘合到皮肤上的能力和由此污染皮肤的风险。
在第四方面，本发明涉及包括粘合层的安装垫在用于皮下引入插管的插管设备中的使用，所述层具有可移除的释放衬垫，所述释放衬垫被分成至少两个部件，其中，释放衬垫的至少两个所述部件中的每个都具有一条或多条划线，由此将释放衬垫的每个部件限定为条，所述插管设备包括具有上面板和下面板的壳体、以及连接到下面板的插管，其中，安装垫与下面板连接布置并用于将插管设备固定到皮肤上。

附图说明
下面将参照附图对本发明进行更详细的解释，其中：
图1示出按照本发明的安装垫的一个实施例；
图2-9示出按照本发明的具有一条或多条划线的释放衬垫的不同的实施例；
图10示意性地示出按照本发明的插管设备在释放衬垫的移除过程中的剖视图，该设备具有包括释放衬垫的安装垫；
图11a-11c示出与粘合层结合的释放衬垫的另一个实施例。
具体实施方式
本发明参照示出本发明的优选实施例的附图进行更详细的解释。这些实施例不应理解为限制本发明在所附权利要求中提出的范围。
图1示出按照本发明的安装垫1的一个实施例，该安装垫1适于布置在插管设备的下面板上或用作例如膏药或敷料。按照本发明的安装垫1可以被构造为多种形状，例如大体圆形、椭圆形、三角形、矩形等。安装垫通常包括粘合层2和可移除的释放衬垫3，该粘合层2是本身已知的对皮肤无害的粘合剂，该释放衬垫3覆盖粘合层2。图1中的安装垫1从上面示出，其中由于粘合层2覆盖了中心部分，因此只可以看到释放衬垫3的突出的操作部分，释放衬垫3和粘合层2具有中心孔7。
图2-9示出按照本发明的安装垫1的不同实施例，其中，释放衬垫具有不同形状和位置的划线4。图2-9中的实施例示出被分成两个部件3a、3b的释放衬垫的不同实施例，每个所述部件3a、3b具有至少一条划线4，从而产生预定的样式，其将释放衬垫的每个部件3a、3b限定为窄条。
图2示出按照本发明的用于安装垫1的释放衬垫3的一个实施例。释放衬垫3被分成两个部件3a、3b，图2a中的实施例具有突耳形式的两个突出部分，第一突出部分6a和第二突出部分6b。图2b中的实施例没有突出部分，代替“突出部分”，两个部件3a和3b的端部6a和6b恰好在靠近安装垫的边界处结束，但是不伸出安装垫的边缘，或者不延伸超过周围的释放衬垫部分。释放衬垫3的两个突出的突耳6a、6b从安装垫1的外周突出，并突出超过粘合层2。此外，两个突出的突耳6a、6b相互径向相对地布置。释放衬垫3具有一个连续的划线4，该划线在第一突出的突耳6a附近的释放衬垫3的外周上具有起点，所述划线4成螺旋状且作为完整的线从第一突出的突耳6a延伸到释放衬垫3的中心，并且作为相合的螺旋线从释放衬垫3的中心继续延伸到释放衬垫3的外周处第二突出的突耳6b附近，从而将释放衬垫3分成部件3a、3b。当抓住两个突出的突耳时，从下面的粘合层2移除释放衬垫3只需要小的力和短的拉动长度，并且释放衬垫3可以同时从两个端部6a和6b被撕成两个单独的条，从而暴露粘合层2。
图3示出按照本发明的也可以用于安装垫1的释放衬垫3的另一个实施例，并且释放衬垫3具有与图2中的实施例相同的特征。此外，释放衬垫具有中心孔7，两条连续的划线4a、4b作为完整的线成螺旋形地向释放衬垫3的中心孔7延伸，第一划线4a在一个突出的突耳6b附近的释放衬垫的外周上具有起点，第二划线4b在另一个突出的突耳6a附近的释放衬垫的外周上具有与释放衬垫3的外周上的第一划线4a的起点径向相对的起点。两条划线4a、4b各自以左螺旋和右螺旋布置，并且相互分离或者以一定的间隔布置，在其之间限定了条的宽度。划线4a、4b径向相互相对地在中心孔7的外周上终止。当抓住突耳时，从下面的粘合层2移除释放衬垫3只需要小的力和短的拉动长度，并且释放衬垫3可以同时被撕成两个单独的条，从而暴露粘合层2。
覆盖图2-10中的安装垫1粘合层2的释放衬垫3优选地由渗硅纸或聚乙烯片制成，其可以容易地从粘合层2移除，而不会损坏粘合层。
划线4、4a、4b可以是冲压或切割点、槽、或完全割穿释放衬垫3材料的间断线的形式，或者是不割穿释放衬垫的材料但提供削弱结构的连续的线。此外，限定释放衬垫的每个部件3a、3b的划线4、4a、4b可以被形成为曲线划线，例如螺旋形的划线、正弦曲线划线、直的划线或上述划线的组合。划线4、4a、4b相互不相交。用这种方法，每个部件3a、3b同样地将按照划线4、4a、4b被成形为曲线的、螺旋形的、正弦的或成角度的窄条。
在图4-9中示出的实施例中，第一划线4从第一突出的突耳6a到达第二突出的突耳6b，或者从突出的突耳6a、6b到达中心孔7，此外划线4可以从第一划线4和/或从释放衬垫3的外周延伸。
在本发明的一个实施例中，由释放衬垫3的一个部件形成的每个条具有在突出的突耳6a、6b处的第一端和第二端6c，该第二端6c可以位于释放衬垫3的外周或中心部或者位于其之间。第一端6a、6b可以被固定到基部以固定释放衬垫3，这使得当安装垫1远离基部时，释放衬垫3连续地移除。该基部可以例如由用于安装垫1的包装，或者如图10中所示用于输注套件的包装8提供。当构成释放衬垫3的条的第一端被固定到包装上时，条的第一端将相对于基部稳定地固定，并且当例如通过拉动附接到安装垫1上的操作部分来移除释放衬垫时，将发生释放衬垫的自动释放，用这种方法，使用者将完全地避免接触粘合层2，并且即使在手的灵活性降低的情况下也可以操作释放衬垫3。
在使用中，释放衬垫从按照本发明的安装垫1上移除，这借助于将释放衬垫的每个部件3a、3b的点保持在安装垫1的突出的突耳6a、6b附近的第一端、然后借助于以单个直线拉力拉动而移除释放衬垫实现。当以这样的单个直线向上的拉力从粘合层拉动释放衬垫时，释放衬垫以两个或多个窄条被移除。由此，采用移除释放衬垫所需的小的力的均匀拉动将被保持。此外，当释放衬垫被分成两个或多个条时，释放衬垫的拉动长度被减小，所述条借助于单个直线向上拉力被同时移除。
在按照本发明的安装垫1的释放衬垫的另一个实施例中，每个部件3a、3b的每个条的宽度小于安装垫1的最宽的点的宽度的一半。当所述条变窄时，在将释放衬垫从安装垫1的粘合层2撕开时需要的力减小。
安装垫1可以包括孔7，孔7是通过安装垫1的粘合层2和释放衬垫3的孔或开口。孔7位于安装垫1的外周中，并将正常地位于安装垫1的中心部分处或中心部分附近。孔7可以是任意形状或形式，其允许例如插管或气门延伸通过例如椭圆形、圆形、三角形的孔7。
图10示出按照本发明的一个输注设备的一个实施例，其中，覆盖安装垫1粘合层2的可移除的释放衬垫3在输注套件11从包装8释放的过程中被移除。输注套件11用于插管9的皮下引入，该插管9从输注套件11的近侧延伸。输注套件11与手动插入物10或操作设备结合，该插入物10使得操作和插入输注设备成为可能。安装垫1与输注套件11的下面板连接地放置，并用于将形成输注套件11一部分的插管设备固定到使用者的皮肤上。释放衬垫3在该实施例中通过两条划线4被分成两个部件3a、3b，由此将释放衬垫3的部件3a、3b形成为条。每个部件3a、3b形成窄的、成螺旋形的条，这样，释放衬垫形成图3中所示类型的双螺旋线。最靠近安装垫1外周的释放衬垫3的每个条的第一端6a、6b(仅第一端在图中被示出)被连接到包装8的内表面上，并且释放衬垫3的其它部分被可释放地固定到粘合表面2上。释放衬垫3的第一端6a、6b可以通过胶合、焊接或机械地固定到包装8上。当例如用于自动插入输注套件的插入物(未示出)被向下推动以连接到输注套件11时，输注套件11将被锁定到插入物，同时释放衬垫的每个条的第一端6a、6b朝向包装8的内表面向下压，并例如采用胶合物固定，所述胶合物被放置在包装8内部中与第一端6a、6b相对应的点处。当从包装8抽出输注套件11时，释放衬垫3被自动地从粘合层2撕开。
该操作是容易的，并且释放衬垫3的撕裂可以被避免。该操作将以与在没有输注套件11时使用安装垫1的情况相同的方式发生。
在一个实施例中，按照本发明的输注套件11是用于例如胰岛素的药物的输注的输注套件。在按照本发明的另一个实施例中，皮下插入设备是用于测量患者体内葡萄糖水平的通过皮肤的传感器。
图11a、11b和11c示出释放衬垫3的另一个实施例，其中，划线4的起点5被完全地割穿，实际上，材料在释放衬垫3的外周、在图11a的实施例中的划线4的起点5处已经被移除。划线4的起点5被限定为释放衬垫3的部件3a、3b中从粘合层2释放部件所开始的位置。这具有更容易开始撕开划线4的效果，于是这保证了当拉动粘合层2离开释放衬垫3时将释放衬垫3从粘合层移除的成功率的增大。当割穿释放衬垫3，而不是制作划线时，释放衬垫3中的割穿线的切割长度将提供给释放衬垫3的邻近边缘。割穿线(也就是划线4被完全地割穿的部分)的长度将通常小于2mm，但是可以具有任意长度。
在图11a中的实施例中，释放衬垫3与粘合层2相比具有增加的表面面积，这在图11a中被示出为释放衬垫3的增加的直径，这意味着释放衬垫3从上面可以被观察为围绕粘合层2的圆形条，而不是仅仅在突出的操作部分6a和6b处。释放衬垫3的增加的表面具有这样的效果，即可以使靠近释放衬垫外周处的部件3a、3b的起始部分5具有对粘合层2的很小的粘附力，而释放衬垫3的部件3a、3b仍然具有使得在将释放衬垫3从粘合层2分离时被撕裂的可能性较小的尺寸(特别是一定的宽度)。
因此，可以通过使每个部件3a、3b的一部分延伸超过粘合层2而至少部分地控制对粘合层的粘附力。实现上述的一种方法是使每个部件3a、3b的最靠外的部分的宽度的所限定部分延伸超过粘合层2，也就是，沿由最靠近释放衬垫外边界的每个部件3a、3b形成的条的纵向方向，粘合层2将仅覆盖释放衬垫部件的例如一半或2/3。
为了使释放衬垫部件的移除容易开始，两个相邻的部件之间的角度(由划线4的起点提供的开口的角度)在起始位置应当小于90°，甚至小于30°。
图11c示出形成部件3a和3b的划线4a和4b是如何位于安装垫的粘合层2下面的。
图11a-c中示出的特征可以结合前面描述的实施例中的任一个使用。
