Abstract

用于容易而且简单地把一个小管的开口端与一个用于把一个注射器与一个盛药瓶联接起来的装置联接起来的器具，该器具包括一个与小管相联接的空心状成型壳体。这个空心壳体用一个塞封闭着，形状象一个普通药瓶的瓶口的一个凹缘从上述壳体上突出，该凸缘轴向延伸并在壳体上形成有一个连续的环形凹槽，其形状和结构使得当把所述器具插入装置中以便联接二者时，从装置上伸出的挠性凸耳的齿与所述凹槽啮合，从而将器具锁固在装置中。

Description

英国专利申请2，176，664A号公开了一个用于联接的器具。该器具可安全地把传送药的小管的一端连接在一个用于把一个注射器与一个盛药瓶联接起来的装置上。
这个器具有一自由端，该端与所述的装置联接。此器具具有形状大至象用于普通盛药瓶的瓶口的一个壳体。从成形壳体上，有3个或更多的纵向凸棱凸出，所述的凸棱具有一个均匀平坦的纵向外轮廓，并且可保证使所述器具的自由端轴向插入并保证这个器具在装置（盛有药物的注射器联在其上）的支座内被稳固地夹持住。
如上专利申请所述，与注射器联接的装置上有3个或更多个弹性凸耳，每个凸耳有一个齿，当器具的自由端插入所述装置支座中时，该齿即啮合在器具上形成的自由缘下面，这样一种器具在美国专利4，576，211号中已公开。
人们已发现，如果纵向凸棱被装在装置的挠性或弹性凸耳的齿之前，由器具壳体伸出的纵向凸棱的构件（其径向最外面的纵向周缘是平坦的）可能会引起锁固上的问题。事实上，如果安装时装置弹性凸耳上的齿不与器具的凸棱脱开，那么该器具不能被联接到装置上，而使用者可能并没注意这个问题，从而带来非常危险的后果（应记住，许多药是有剧毒的），即在药的输送阶段，该器具可能与装置分离。
因此，本发明的主要目的就是提供一个所述类型的器具，该器具可以很容易地插入所述装置的支座中，而在插入时，总保持一个纵向 定位，并且在自由端摆动的情况下，总是被稳定地夹持在支座中，而且一旦该器具被插入所说的支座后，该器具就与从所述装置上伸出的挠性或弹性凸耳的齿稳固啮合。
这个器具包括一个成形壳体，其中，在第一端上形成一个中空的开口，以便形成使其与一个输出小管联接的凸耳，在第二端上还有一开口，在第二端处有一个中空的闭合弹性塞与其啮合，在所说的塞处，所说的壳体具有一个凸出的凸缘，其形状和尺寸在所说的成形壳体的纵向轴垂直的平面内，是与用于盛药的普通瓶瓶口的形状和尺寸相类似或一样的，其中所说的凸缘轴向延伸一个比一个普通药瓶的瓶口的长度要长的长度，从而形成一个加长的圆柱表面，其上形成有一个连续环形凹槽，所说的凹槽是这样设计和安排的，当将所述器具插入所述装置中以便连接它们时，从装置上伸出的弹性的凸耳上的齿与凹槽啮合从而将其锁固。
为了更好地理解发明对象的结构和特性，下文将公开一个最佳实施方式，参阅附图，其中：
图1是根据本发明的器具的一个透视图;
图2是该器具的一个放大的剖视图。
如图所示的器具包括一个成形壳体1，该壳体被一个圆柱壁定界，在圆柱壁的外表面上，有一个环形凹槽3，在圆柱壁内，沿其轴向有一个凸耳4，该凸耳是一个空心体。该空心体在顶端是开口的（如图中所示），而在其的另一端，它被一个弹性塞5（用橡胶或类似的材料制成）封闭着，弹性塞5借助于一个小的刚性支撑盘6而压在凸耳4的开口端，支撑盘6被固定在圆柱壁2上。
在已知的方式中，在空心的凸耳4的自由伸出端上装有弹性小管 7的一端（该小管的一部分已在图中用虚线示出）。为了把药注入病人的静脉，在空心套管4的另一端可以联接一个头皮针，药被用一个注射针8（它在图2的剖视图中示出）注入空心套管4中，注射针8被安装在一个图中未示出的注射器上。
注射针8也包括在类似于美国专利4，567，211号中公开的那种装置，在图2的下部用虚线示出了，这个装置的端部上有一个支座，以便容纳和夹持根据本发明的器具。
所述支座被一个管状圆柱壁9定界，弹性凸耳10在其中延伸，齿11从每个所说的凸耳上向内凸出。
在装置支座的中心，一个橡胶或类似的材料制成的凸缘12凸出，如图2所示，当所述器具在所说的支座中被锁固住时，凸缘12被紧压在弹性塞5上。
注射针8如何作用于所述装置和器具在此就不描述了，因为在所提到的美国专利4，567，211号中已有清楚的说明。
根据本发明的器具的一个主要特性是圆柱壁2有一个相同于或类似于一个普通药瓶的瓶口的截面的截面;所提到的圆柱壁2轴向延伸一个比其被圆柱壁9和装置的弹性凸耳10限定的安装支座的深度要长的长度，这已在图2中清楚地示出;而环形凹槽3被如此安排和成形，当器具与所提得的装置联接时，弹性凸耳10的齿11将总是进入所说的环形凹槽中，从而将其锁固住。
这意味着当器具一旦插入装置的支座中，弹性塞5压在凸缘12上，齿11将进入环形凹槽3中，因此总是使器具和所述的装置稳定地啮合。
事实上，圆柱壁2按指出的方式轴向延伸也是一个主要特征，因 为按这种方式，给所说的面对装置支座的相邻表面的圆柱体的外表面提供一个很大的放置范围。因此该器具对于装置来说将形成一个几乎刚性的壳体，因为它不能在所述的容纳支座内摆动。
