Abstract

本发明之目的为一新型注射器,有一附加的系统,可在使用注射器后使其失去效用。方法为压迫柱塞管端部以使注射针后退,从而柱塞上的一个鱼枪形尖头在针塞颈部内锁定。柱塞管的侧孔中有活塞体上模压的翅形突块嵌入,从而一旦注射针与柱塞管脱离,再压柱塞管时注射针便被留入针管中不能取出。也可用弹簧自动退针。

Description

本发明为一种新型注射器,它能在使用注射器后将注射针退回到针管内。目的明显是避免传播某些接触传染病的意外事故。

注射器包括一个注射器壳,其中有一个执行注射器一般功能的活塞,但差异为在柱塞管端上安装一个小鱼枪尖头,或相似形状的圆锥体,加一定力时,便可在针塞的内部锁住,因此当将注射针缩回并隐藏时,便有限动机构防止将针取出。

为使下面的说明清晰并易于理解,本说明书中作为它的一部分,有附图纸四页,其中图11幅,举例来表达本发明实质部分。

图1所示注射器剖视图其中有注射针1,针托2,和不使用时将针藏在深孔5中的柱塞管4内,并有突缘3便于将柱塞管4推送。

在图9中,注射器的壳体(9)端部上有开孔10,当柱塞管要藉助鱼枪形尖头11将针脱离针托时,柱塞管的翅形突块14落入注射器壳的孔10中。柱塞管侧部上的槽16为了便于引导突块14在槽内移动。所以柱塞管可分成二部分;第一部分为塑料材料制成的柱塞管,第二部分为保持在塑料柱塞管(5)内的活塞体(12)和中芯(13)。

从图10可见,柱塞管有与鱼枪形尖头11相连的中芯13和活塞体12,有一个稍张紧的Ω形部分,从而当将针退回时其突块就在注射器壳的孔10中锁定。为此,当将针抽回,在突块14上方活塞12锁定在压射器壳9的上部时,如再推送,便将折断横挡15,为了活塞体12与锁定件13及14脱离并带动活塞体上固定的针向下移动,这样便将活塞体及针留存在图中17的区域中。

这注射器按常见的方法使用。针位于图8所示分别的壳体中,藏在柱塞5的后部,在使用时,针就固定在注射管的端部8上,唯一的目的是进行注射,注射后可后退。针的后退是因为有图8所示的两个元件6及7,6为其外壳体,而7为固定针1的内针塞。

针的后退从图2-3,图4-5及图6-7可清晰看见。

从图2-3可见,当用适当的力推压活塞12,听到“咔嚓”一声说明鱼枪形尖头11便通过固定针的针塞7的颈部使该两部分锁定。由于活塞12的材料用塑料制成,所在压力下使鱼枪形尖头11可达到7处,将活塞压扁,鱼枪形尖头便可达到针的后部。

一旦将针夹住在柱塞管上,仅需按与抽吸药液相似的方法,将上述的针缩回,就是拉回柱塞管,直到Ω形部分的突块被卡在注射器壳的孔10内而锁定。从图4-5可见。

在图10中,在横档15上再稍加压便可将横档折断,这样活塞就可达到行程终点,而针固定在针塞(7)中,在针筒的上部被锁紧,不能后退。这如图6-7所示,明显可见在活塞体12和与锁住针的针座13之间保持距离。

图11所示为另一种可行的方案,针可自动后退,与前述方案唯一不同之处,在于在活塞体12与Ω形部分14之间安装一永久弹簧18。这种型式的注射器,除根据弹簧强度外其余都相同。在这实例中,压迫柱塞管使鱼枪形尖头因材料的弹力而插入到针部7中,一旦防止弹簧弹开的横挡14被折断,便将柱塞管的内壁在注射器壳内滑动,注射针后退一如以前各图所示。
