Abstract

本发明涉及一种通过针头(12)将流体药物注射入病人体内的药物注射装置(2)。如果针头(12)在被注射药物从病人体内的注射位置适当地局部扩散之前抽出，则该被注射药物可能通过针刺创口逸出而不扩散入病人体内。不幸的是，当使用者认为已经过适当的扩散时间时，使用者通常变得不耐烦并抽出针头(12)。通常由使用者确定的等待时间少于药物扩散所需要的时间，从而导致上述问题的产生。这里公开的药物注射装置(2)包括一定时器和一显示器(13)，在注射操作开始时致动该定时器，其中该定时器运转至注射操作完成之后的一预定时间，并且在定时器运转时显示器进行操作(13)。

Description

药物注射装置的改进及其相关改进
技术领域
本发明涉及一种药物注射装置。本发明尤其，但不是唯一地用于电子控制的药物注射装置。
背景技术
由WO97/30742已知一种药物注射装置，其中操作一按钮以通过一针头注射一设定剂量的药物。操作一开关以设置一秒表，且当操作该开关时启动该秒表。该药物注射装置还包括一显示器。从一次注射完成的时刻开始计数并显示秒数，以使使用者确保注射结束后针头保持插入一定秒的时间。这种保持是需要的，因为如果在被注射药物从病人体内的注射位置适当地局部扩散之前抽出针头，则该被注射药物可能通过针刺创口逸出而不能扩散进入病人体内。
不幸的是，尤其在病人使用药物注射装置自我注射药物的情况下，当使用者认为已经过适当的扩散时间时，通常使用者会变得不耐烦并抽出针头。通常该适当的时间少于药物扩散所需要的时间，从而导致上述问题。
发明内容
本发明的一个优点是基本上解决这一问题，或至少减轻这一问题。
按照本发明的第一方面，一种药物注射装置包括一定时器(计时器)和一显示器，其中在注射操作开始时致动(启动)该定时器，该定时器在注射操作完成之后运转至一预定时间，并在该定时器运转时该显示器进行操作。
换句话说，不对使用者显示任何注射操作指示。这样，当显示器停止时，使用者可以安全地抽出针头。由于使用者不知道何时注射操作已经停止，因此使用者不能猜测何时可以抽出针头而不会引起上述问题产生。
优选地，显示器包括当定时器运转时在离开(脱离)和返回一预定状态之间交替切换的多个图标(图符)。
更优选地，多个图标中的每一个以预定顺序在离开和返回预定状态之间切换。
最优选地，第一图标的预定状态是“开”(on)状态，多个第一图标中的每一个以预定顺序被关闭然后重新打开。
优选地，在一预定的时间段内，多个图标中的每一个在离开和返回预定状态之间切换。该预定时间段通常包括几分之一秒。
附图说明
现在将参照附图仅以示例的方式说明本发明，其中：
图1示出按照本发明的药物注射装置的示意图；以及
图2示出适用于按照本发明的药物注射装置的显示器。
具体实施方式
参照图1，公开了按照本发明的药物注射装置的一种示意性设置。该药物注射装置2包括一壳体4，一控制单元或微处理器6，一驱动装置8，一活塞10，一针头12和一显示器13。
一优选为可更换的药物筒14位于活塞10和针头(针单元)12之间。该药物筒14包括在第一端的适于由针头穿刺的一封闭件，和一位于朝向药物筒的第二端并适于由活塞10朝向药物筒14的第一端驱动的可移动柱塞。
控制单元或微处理器6包括一与之相连的定时器。在使用时，设定待注射的药物剂量。然后致动驱动装置8以驱动活塞10。驱动装置8可机械致动或在控制单元或微处理器6的控制下致动。然后从药物注射装置2的药物筒14中将药物推出。
定时器在注射操作开始时被致动。让定时器运转到注射操作完成之后的一定时间，且在定时器运转时显示器进行操作。在注射操作完成之后的该时间是足以使被注射药物从病人体内的注射位置充分地局部扩散的时间。随着定时器运转，在显示器13上提供经过的时间指示。
现在参照图2，其示出用于本发明的显示器13。该显示器13包括多个第一图标20A-20Z，每一个第一图标均可在微处理器6的控制下从一预定状态打开或关闭。显示器13也可包括另外的图标22以提供另外的参数指示，这些参数包括但不限于所要注射的剂量的大小，时钟和/或错误信息。
在一优选的实施例中，在注射操作开始前打开所有的第一图标20A-20Z。这表示第一图标的预定状态。当定时器启动时，最下面的第一图标20A暂时(短暂)关闭。当这个图标20A重新打开时，随后上面的图标20B暂时关闭。这个过程一直重复到最上面的第一图标20Z暂时关闭。然后这个图标20Z再次打开，并且最下面的第一图标20A再一次暂时关闭。
只要定时器运转就继续上述顺序。
多个第一图标20A-20Z中的每一个可关闭所需要的时间长度。然而已发现一个短的时间，例如几分之一秒，在产生一种循环显示中是有用的。
应当理解多个第一图标20A-20Z可采用其它形状和以其它排列设置。
在一可选实施例中，所有第一图标20A-20Z可一起暂时打开和关闭，以使使用者确认注射操作即将开始。
在一可选实施例中，第一图标的预定状态可以是关闭状态，其中循环显示的出现由按顺序打开然后关闭的各个图标产生。

Claims (5)

1.一种药物注射装置，它包括一定时器和一显示器，该定时器在注射操作开始时致动，其中该定时器运转至该注射操作完成之后的一预定时间，且该定时器运转时该显示器进行操作。
2.一种按照权利要求1的药物注射装置，其特征是，该显示器包括当定时器运转时在离开和返回一预定状态之间交替切换的多个图标。
3.一种按照权利要求2的药物注射装置，其特征是，该多个图标中的每一个以一预定顺序在离开和返回该预定状态之间切换。
4.一种按照权利要求2或权利要求3中的药物注射装置，其特征是，该第一图标的该预定状态是一“开”状态，且该多个第一图标的每一个以一预定顺序关闭然后再次打开。
5.一种按照权利要求2到3中任何一个的药物注射装置，其特征是，在一预定的时间段内该多个图标中的每一个在离开和返回该预定状态之间切换。
