Abstract

本装置包括一个插座体，插座体上设置有用于将其连接到瓶子或类似物的一端的部件，并有一支座用于安置注射器的自由端，其上有一注射器针可以穿过的孔。该装置还包括一注射器，注射器自由端可以被拧在上述支座中。在支座的相对表面和插入到支座中的注射器的端部，制成径向凸出的轴向齿和相应的倾斜弹性肋片，当注射器拧进支架时，肋片被变曲，注射器支撑在肋片上，防止注射器从支架上脱落。

Description

本发明涉及到将注射器牢固且不可逆转地锁定在与注射器相连接的插座体上的装置。
众所周知，注射器上配备有可以从瓶子或类似物中撤出或插入的针，或者吸入或排放小管的成形端，通常具有药物特性的液体通向该端部，注射器可能处于自由状态并自由地与瓶子连接，或者它被固定到一个在瓶口有锁定部件的器械上。美国专利第4，576，211号公布了这种器械，并作了图解说明。这种器械有一个密封腔组成，针通常在密封腔内，只有当器械被牢固地固定在瓶子或类似物的口上时，针才从中伸出。
对于某些用途和场合，考虑到注射器有可能从它所连接的插座体上松开，这是危险的或不希望发生的。例如，注射器从上面所提到的美国专利所公布的器械上脱离，或从内静脉注射小管的成形端脱落，都是危险的。其中某种非常危险的药物，例如一种细胞抑制药会被注射器注入。
因此，本发明的主要目的在于提供这样一种装置，用来防止注射器从其已经连接的插座体上脱离。
按照本发明的一个方面，可以由这样一个装置来实现上述目的和其它目的，该装置由插座体和注射器组成，插座体上装配有将其连接
到瓶子或类似物、或者细管的端部的部件，并有一插座体来安置注射器的自由端，其中有一个已经成形的孔，使得注射器针可以穿过;注射器自由端被安装在上述支座中，注射器针从上述孔中穿过，在上述支座中和上述注射器上，制成互相配合的螺纹，使得上述注射器和插座体能通过螺纹连接，在上述支座的相对表面，以及相应的插入到上述支座中的上述注射器的一端，设置有径向凸出的轴向牙齿，以及相应的倾斜弹性肋片，反之亦然，当上述注射器被拧进上述插座体时，上述肋片被上述齿所弯曲，注射器支撑在肋片上使其不能从上述插座体上脱落。
为了更好地理解按照本发明的装置的结构和特性，下文中将公开一个最佳实施例，并参考附图，其中，
图1大略地表示该装置安装好情况下的轴向剖面图。
图2是该装置沿图1中Ⅱ-Ⅱ线的剖面图。
图解说明的装置包括插座体1，装配有将其固定到装药的瓶子或类似物口上的部件（为了简化，并考虑到有不同的方法，这些部件图中未表示），其中管状园柱形壁2构成了一个支座，可以安置注射器4的自由端3，注射器针5可以从上述支座的中心孔中穿出。
在这一公开的实施例中，插座体1（其端部如图所示）含有一个如美国专利4，576，211号所公布的器械，用来在安全情况下，将装药的瓶子连接到注射器上;针5被牢固地锁定在支架1中，连接环6从中凸出，通过注射器自由端内部的螺纹7与注射器自由端相啮合。
很明显，插座体1可以和所提到的美国专利中的插座体不同。例如，插座体1可以配备有管状园柱形壁，沿与壁2相对的一侧延伸，
而且它可以被拧进或用力推进到瓶子或类似物开口上;或者是，一根细管的自由端可以简单地固定到插座体1的突出部8上，颅盖针（epicranial    needle）可以固定到细管的另一端，以便进行静脉输血。
如图所示，注射器端部3的外表面具有包含由多个齿9构成的齿状结构，齿9轴向延伸，其表面倾斜度如图2所示。从管状壁2的内表面凸出的弹性倾斜肋片10和齿9配合;很明显，当注射器被拧入插座体1的支座，肋片10被齿9弯曲，使得注射器能够自由地旋转，牢固地与插座体1连接在一起。另一方面，在注射器被连接到插座体1以后，如果打算卸下来，那么肋片10（或者至少是其中某些）用其自由端顶紧齿9，防止注射器沿逆时针方向旋转（根据图2）;这样，注射器可以被牢固地和插座体1连接在一起。
显然，齿也可以制作在管状壁2的内表面，而肋片从插入到插座体1的支座内的注射器端部的外表面凸出，得到与图示的实施例相同的效果。

Claims (4)
