Abstract

用于多料筒或注射器的分配器具(1)包括：用于容纳料筒(8)的具有内螺纹(24)的外壳(2)；和具有互补螺纹(22)的可旋转部分(4)，这两个部件以相互旋转的方式协作，该可旋转部分能够相对于外壳沿分配方向连续地移动。将外壳构造成容纳具有两个相邻的存储容器(14、15)的料筒，以及将可旋转部分(4)的推力传递到多推杆(10)而不会出现任何卸压。这种布置使得能够在高压下利用很小的手动力并以精确计量的方式从料筒分配即便是高粘的物质。

Description

用于多料筒的分配器具
技术领域
本发明涉及一种用于多料筒的分配器具，该分配器具包括用于容纳料筒的具有螺纹的外壳，以及具有互补螺纹的可旋转部分。
背景技术
此类分配器具得知于DE 10128611A1，该器具具有两个同心设置的存储容器，和包括推杆的可旋转部分，该推杆具有内推杆部和外推杆部，其中外推杆部设有螺纹。
CH-322201同样公开了一种分配器具，其中存储容器是同心设置的，并且分配活塞的杆中的一个设有螺纹部分，该螺纹部分与位于内部存储筒的中央的相应螺纹部分协作。
还存在大量这样的分配器：其中，外壳的一部分相对于用于挤出药物及类似物质的另一部分旋转，例如US 2003/0089743A1、US22002/0166878A1和美国专利No.4,623,337。然而，所有这些现有技术文件公开的都是单构件料筒或注射器，它们所致力于解决的问题要简单得多。
另一种是公开于美国专利No.3,952,920和EP 0621083A1中的带有螺纹分配移动和两个相邻存储筒的分配器，其中，中央螺杆支承在推杆上。这种解决方案并不适于医学用途，且非常难于消毒。
此外，在市场上能够买到用于分配双组分物质的双料筒用手动操作分配器，它们被设计成枪的样式，例如美国专利No.5,535,922。在杆传动机构的回移过程中，解除了双推杆，并导致料筒完全卸压，从而中断了物质流。因此，对骨接合剂的应用特别有利的精确计量应用是不可能的。此外，在高粘物质的情况下，由于需要高倍增系数并由此需要复杂的机构，或者必须施加较大的力这样的事实，从而对这种器具施加了限制。
发明内容
在所述现有技术的背景下，本发明的目的是提供一种分配组件，包括分配器具和多料筒或注射器，所述分配器具包括：用于容纳所述多料筒或注射器的具有螺纹的外壳；和具有互补螺纹的可旋转部分，所述外壳和所述可旋转部分以相互旋转的方式协作，使得所述可旋转部分能够相对于所述外壳沿分配方向连续地移动，其特征在于，将所述外壳构造成容纳具有至少两个相邻的存储容器以及多推杆的料筒或注射器，并且将所述可旋转部分的推力传递到在所述多料筒或注射器的所述存储容器中滑动的所述多推杆，由此，所述可旋转部分在其出口侧设有居中设置的支承件，所述支承件具有球形支承表面，所述球形支承表面与所述推力板上的相应球形支承表面相对应，所述支承件对所述多推杆的推力板施加作用，所述推力板以不可旋转的方式在所述外壳内被引导。
附图说明
将参照示例性实施例的附图在下文中更为详细地论述本发明。
图1示出了根据本发明的分配器具的立体图；
图2示出了图1所示分配器具的分解图以及双料筒的各个元件；
图3示出了图1所示器具的纵截面图；以及
图4示出了根据图3中的线IV-IV的截面图。
具体实施方式
如图所示，根据本发明的分配器具的原理基于相对彼此旋转的两个部件的相互穿插，借此，可实现连续而精确的计量供给。在下文中，示例性实施例中的术语“双料筒”代表多料筒或注射器。在这一点上，对于本领域技术人员来说，很明显的是，在存储容器多于两个的情况下，必须设置相应数量的活塞和推杆。
图1示出了具有外壳2及其握持区3以及可旋转部分4的分配器具1，可旋转部分4设有旋转凸耳5。这些部件同样示于图2中。这里，在分配端处示出了常规混合器6和常规封盖7。在外壳2和可旋转部分4之间，设有带活塞9和双推杆10的双料筒8。
此外，在图1和2中，在外壳2入口侧的外壳部分11上设有刻度12，并在外壳2的握持区3上设有隆起部13，从而确保旋转地牢固握持。
料筒8具有两个相邻的具有相同直径的存储容器14和15。然而，存储容器也可分别具有不同的直径或容积。料筒还包括两个出口16和17以及卡口插座18。如图1和3所示，卡口插座18靠在位于外壳2的握持区上相应成形的卡口加强件19上。
在图3中明显看到，可旋转部分4基本由具有外螺纹22的内部圆筒21以及圆筒形的外部套筒20构成。位于套筒20出口侧的端部23用作与外壳2上的刻度12协作的指示器边缘，用于指示所分配的容积。
在图3中还能够看到，外壳2的外壳部分11设有与可旋转部分的内部圆筒21上的外螺纹22协作的内螺纹24。从可旋转部分到双推杆的力传递通过可旋转部分4的分配侧的支承件25来实现，该支承件25具有居中设置的球形支承表面26，该支承表面26与位于双推杆10的推力板28的中央的相应球形支承表面27协作。这种布置确保了仅有较小的扭矩传递到推力板。该扭矩由外壳部分11中的两个导槽29吸收，参见图4，在导槽29中引导推力板28上的两个相应的凸轮30。为了使得推力板28能够移动，所述内螺纹具有两个呈槽31形式的相对的通道。
在图3中，示出了所述器具准备好进行分配时图2所示元件。通过螺纹来传递力使得能够无需耗费较大的力即对高粘物质进行分配，同时还基本上避免了推杆完全卸压以及因此而造成的物质流中断。
