Description

具有阀组件的多组分配给装置
技术领域
本发明涉及一种多组分配给装置，该多组分配给装置具有至少两个容器以及阀组件，该阀组件具有入口/出口。通过本发明申请人的WO2005/018830已知这种具有阀组件的装置。
背景技术
这样的具有阀组件的装置对于多组分注射器尤其有利，该多组分注射器具有用于液体的容器和用于粉末的容器，其中，预填充的液体被传输到粉末以便与粉末混合并且随后进行配给，或者液体从外部被吸入以被传输并与粉末混合并且随后进行配给。由三通阀组件提供关闭、吸入、传输和配给的四种功能。
发明内容
基于该现有技术，本发明的目的是提供一种更简单并且更有效的阀组件。这通过一种如下的阀组件实现。一种具有多组分注射器或筒的配给装置，包括至少两个容器和具有共用入口/出口的阀组件，所述至少两个容器包括第一容器和第二容器，所述阀组件设计成在至少四个位置中选择性地将其至少一个共用入口/出口连接到所述第一容器的出口、或连接到所述第二容器的出口、或者将所述至少两个容器第一容器的所述出口与所述第二容器的出口相互连接、或者关闭所述注射器或筒，其特征在于，所述阀组件包括具有所述至少一个共用入口/出口的阀体和至少一个密封盘，所述密封盘中的至少一个设置在所述阀体上，所述密封盘具有沟槽，所述沟槽设置成使得通过旋转所述阀体而能够选择所述至少四个位置。
附图说明
以下将参照示例性实施方式的附图详细说明本发明。
图1示出根据本发明具有阀组件的双筒注射器的立体图；
图2至5示出在不同位置时图1的阀组件的纵剖面和对应的平面图；
图6示出从面对容器的侧面观察时阀组件的阀体；
图7示出从面对阀体的侧面观察时的密封盘；
图8示出从面对容器的侧面观察时、具有安装在其上的密封盘的图6的阀体；
图9示出双筒注射器的出口侧的立体图；和
图10示出紧固环的立体图。
具体实施方式
根据图1的双筒注射器1包括两个容器2和3以及保持凸缘4，较小的容器通常用于容纳液体，而较大的容器3用于容纳粉末。与根据WO2005/018830的图13的示例相似，混合杆5延伸到粉末容器3中，可拆除的推杆6延伸到液体容器2中，混合杆延伸并穿过活塞。
如在前文献披露的那样，能够借助于混合杆搅拌粉末与液体的混合物并利用容器2的推杆6配给该粉末与液体的混合物。关于这种双筒注射器或筒可能的示例性实施方式和应用，可清楚地参考所引用的文献。
出口侧上设置有根据本发明的阀组件9，套管或针10通过Luer-Lok连接器固定在该阀组件9上。代替Luer-Lok连接器，可提供另一出口构造。
阀组件9通过紧固环11保持并紧固到双筒注射器1上。在当前示例性实施方式中，紧固环呈可拆除的卡口环的形式，但其也可被设计成螺纹环或扣环，或者阀组件能够被粘结或焊接到注射器上。
在图2至5中，示出装配在四个位置的阀组件9的部件，即阀体12和密封盘13。在这些附图中每一个下方的平面图示出密封盘相对于容器出口的位置。共用的入口/出口15通向阀体。
在阀体12的连接凸缘12A的上侧设置有定位突出部23，并且在相对侧上设置有手柄翼部24，定位突出部和手柄翼部有助于阀体用于相应功能的旋转和定位。为此，区域26设置在紧固环的外侧，用于容纳定位标记，见图1。
图6示出阀体12的细节。在连接凸缘12A面对容器的侧面上，该连接凸缘12A包括四个驱动销32，所述四个驱动销32对应于密封盘中的驱动凹口31。此外，在连接凸缘面对密封盘的表面上设置有四个导向段33、34、35、36，所述导向段中的至少两个设置有凸轮25，所述凸轮25与双筒注射器的卡口环8中对应的切口18配合。这提供了用于阀体的对应的卡合位置。
在连接凸缘的下侧上，止动件22设置在导向段36上，该止动件22与卡口环8内径上的两个止动件37和38配合，并允许阀仅沿合适的方向旋转。因此，阀的关闭、吸入、传输和配给位置仅仅能够以该特定的顺序选择。
在图7和8中，详细示出了密封盘13。在图8中，示出面对容器的表面27，其包括通道28和传输沟槽29。除通道28以外，朝向出口或阀体的图7所示的另一侧还包括四个驱动凹口31。密封盘由比其它塑料部件软的材料(例如硅树脂或聚氨酯)制成，以便实现其密封功能。
根据图9，双筒注射器1的容器2的出口16和容器3的出口17设置在出口凸缘7中。出口凸缘设置有卡口环8，并且卡口环8具有卡口凸耳19与19A，用于容纳紧固环11上对应的卡口突出部20、20A。
如附图中所显现的那样，对于密封盘的组件，密封盘以其四个紧固凹口31置于驱动销32上并且被下压，并且密封盘在通孔28对齐阀体的共用入口/出口15的同时由导向段定位。因此该密封盘以不能旋转的方式连接到阀体。
参见图10，通过紧固环11将阀体固定到双筒注射器1的出口凸缘7上，其中紧固环的卡口突出部20、20A在下面接合双筒注射器的卡口环8的卡口凸耳19、19A。为了提供可靠的、可能不可拆卸的连接，环上的卡口突出部包括例如呈阶梯21形式的卡扣装置，该卡扣装置与卡口凸耳下侧上对应的凸轮39配合。
通过旋转阀体和连接到该阀体上的密封盘，容器2和3的入口/出口16和17能够选择性地打开、关闭、相互连接、或连接到阀体中的入口/出口15。
以下，参照图2至5说明四个阀位置：
在图2中，两个容器出口16和17都关闭。传输沟槽29在功能上处于中性位置。
在图3中，旋转90°之后，液体容器2连接到密封盘的通道28和阀体的共用入口/出口15，使得能够吸入液体。
在图4中，具有密封盘的阀体相对于图3的位置旋转90°，使得两个容器出口16与17经由传输沟槽29相互连接，从而液体能够从容器2传输到容器3。
在图5中，示出再旋转90°之后的具有密封盘的阀体。来自容器3的出口17连接到密封盘的通道28和阀体的入口/出口15，使得能够从容器3配给混合组分。
在所有的吸入位置或配给位置中，重要的是，吸入操作并且主要是配给操作能够以直线形式进行，而无偏离或突出边缘，使得在这些功能期间产生最小的压力损失。此外，密封盘中短的传输沟槽确保在液体到容器3的传输期间最小的体积损失。
尽管已通过具有两个容器的单个示例性实施方式说明本发明，但本领域的技术人员应理解该发明的理念也可适用于其它装置，例如可适用于具有多于两个容器的注射器或筒的配给器械，如已在引言中引入的公开文献中所披露的那样。在具有多于两个容器的装置中，必须相应地调适阀组件、尤其是密封盘。
在具有以合适构造(例如三角形构造放置的三个容器的配给器械中，可以合适地使用两个密封盘，该两个密封盘中至少一个设置在阀体处。
此外，根据本发明的阀组件也可用于没有搅拌装置的容器。
此外，在特殊情况下在阀体中利用独立的入口和出口的实施方式是可能的，以避免在吸入操作期间残留在共用入口/出口中的液体在混合组分之前被配给并进入身体。
