Abstract

用于双注射器的分配用具，其包括双柱塞(4)，所述双柱塞(4)通过推板(5)以及凸缘保持器(6)连接，所述凸缘保持器(6)具有用于接收双注射器(1)的保持凸缘(9)的导向凹槽(8)和至少一个指托夹(7)。这种分配用具使分配更容易，尤其是较小双注射器的分配。

Description

用于双注射器的分配用具
总体上，带有静态混合器的双注射器或双药筒用于混合并分配两组分材料。双注射器系统总体上包括两个平行布置的存储圆柱体、两个活塞、一个共用封装体、和双柱塞。为了分配该内容物，活塞通过双柱塞向前推进。
特别地，在较小的一次性双注射器中，由于尺寸小，因而通过双柱塞进行常规分配可能引起操作问题。因此，本发明的目的在于提供分配用具，所述分配用具允许小的双注射器也具有舒适的分配。该目的通过权利要求1所述的分配用具实现。
EP-A2-0315222公开了一种分配设备，其中两个注射器在其出口端处通过带有共同出口的连接部件且在进口端处通过桥接该两个柱塞而保持在一起。该设备未解决小注射器的问题，也未在其中提出该问题。
本发明将在其后参见示范性实施例的附图更详细地阐述。
图1显示根据本发明的分配用具和带有混合器的双注射器的透视图；
图2显示插入到图1的分配用具的图1的双注射器；
图3显示图2的分配用具；
图4显示根据图3的箭头IV的局部截面图；
图5显示根据图4的线V-V的截面图；
图6显示根据图4的柱塞端的放大图；
图7显示分配用具的实施例变型中的双注射器；和
图8单独显示图7的分配用具的透视图。
图1显示带有混合器2的双注射器1、以及本发明的分配用具3的第一实施例，分配用具3带有双柱塞4，所述柱塞4通过推板5、以及凸缘保持器6连接，所述凸缘保持器6具有带有指托(finger rest)7F的指托夹7和用于接收双注射器1的保持凸缘9的导向凹槽8。在凸缘保持器的注射器侧上设置套圈7A，套圈7A用于导向注射器且包括用于首先插入的容器的注射器卡扣保持器，在此情况下容器体积不同于1:1较大容器。此外，在图1中显示注射器中的活塞10。
图1显示已填充的和操作的注射器1如何能够用其保持凸缘9引入分配用具的凸缘保持器的导向凹槽8中。导向凹槽8的内轮廓适合保持凸缘9的编码外轮廓，从而防止使用非系统注射器且确保在具有容积比(相应地直径比)不同于1:1的容器的注射器中，注射器插入到导向凹槽的正确位置。
在图2中，注射器在分配用具上就位，且双注射器的内容物的部分已经被分配，所述内容物跟随活塞和柱塞的位置。
在图3中，清楚的是，双柱塞4的前端11具有切口12，以提供这些端部的一定弹性。在柱塞端的图6放大图中，可以看到端部弹性地稍微张开，且具有周向凸起13，使得柱塞端部具有比柱塞其余部分稍大的直径。通过周向凸起13的该周向增大和双柱塞4的端部11处的轻微张开具有这样的效果：当双柱塞回拔时，它首先被制动，且仅能通过施加增加的力从柱塞导向器14撤出。当施加法向力时，周向凸起对柱塞从凸缘保持器完全撤出提供足够的安全性。
在图4中，示出了双柱塞通过足够长的柱塞导向器14引导，柱塞导向器14布置在指托夹上且向推板延伸。这允许精确的施用，这在较小的双注射器中尤其重要。
图5图示了带有指托夹7及其指托7A以及导向凹槽8的凸缘保持器6，导向凹槽定形为接收双注射器的编码和弧形保持凸缘。
图7和8图示了实施例变型，其中分配用具15的凸缘保持器16具有带有指托17F的第二指托夹17，第二指托夹17布置在柱塞导向器18上离第一指托夹7一定距离处。通过该第二指托夹，减少了到推板的距离，从而允许注射器的舒适操作，对具有较小的手的人来说同样如此，尤其是在较长的注射器的情况下。分配用具的其余部分与前述示范性实施例相同。
术语“双注射器”也意味着包括双药筒。此外，除了混合器之外，任何其它附件(如喷嘴)或另一附属部件可连接到双注射器。
