Description

注射器
技术领域
本发明涉及这样一种注射器，它包括一个外壳、一个在外壳内的剂量设定机构、一个注射钮、一个针头接收件，可以在这种注射器中通过剂量设定机构设定药剂量并可以通过按动注射钮并经过安装在针头接收件上的针头将这些药剂从安放在外壳内的安瓿中压射出去。
背景技术
这样的注射器主要被设计用于让病人且主要是糖尿病患者使用，这些糖尿病患者必须经常自己注射根据个人情况而设定的胰岛素剂量。注射器通常被赋予自来水笔的形状，因而病人可以每天都携带这种注射器并随时可以用它来注射。安瓿可能装有足供几天使用的药剂，但是必须在一次注射后取掉用过的针头并在下一次注射前换上一个新针头。这说明需要病人不得不随身携带的额外针头。另外，可能需要其它类型的器件如血糖浓度检测条和这样的药片，即如果病人患的是II型糖尿病，则这种糖尿病部分靠上述药片进行治疗而部分靠胰岛素注射进行治疗。因此，注射器主要以小盒的方式交付使用，而在这样的小盒中装有注射器、许多针头和可能有的内装药剂的安瓿等。但是，与当初将笔形注射器设计成一个集中了所有最需要部件时的设计初衷相比，这已经使得病人变得更加累赘了。尤其是需要备用针时，更是如此。
从EP697222中知道了一种通过一个具有相向C形部的夹子将一个装有许多针头的管固定到笔形注射器上的方案。这个解决方案仅仅将具有两个待携部件的不便性转化成要携带一个大体积部件的不便性。
发明内容
本发明的目的是提供一种避免了上述不便之处的注射器，
上述目的是通过如下注射器实现。
一种注射器，它包括一个具有容纳一个安瓿的空间的外壳、一个在外壳中的剂量设定机构、一个注射钮和一个针头接收件，在此注射器中，可以通过剂量设定机构设定药剂量并可以通过按动注射钮并经过一个安装在该针头接收件上的针头将上述药剂量从一个安放在外壳中的安瓿内压射出去，其特征在于，所述外壳呈盒形并包括一个可被该注射器的使用者触及的腔室，用于贮存一个或多个附件。
根据本发明，此腔室具有一个能使其容纳至少一个存放在一个针盒内的针头的尺寸。
根据本发明，此腔室可能是一个在外壳中被一个盖盖住的槽，或者它可能是这样一个帽或抽拉盒的内腔，即所述帽安装在外壳上或所述抽拉盒滑入外壳中。
以下参见附图来进一步描述本发明。
附图说明
图1示出了一个具有本发明腔室的注射器，所述腔室被一个帽封闭；
图2示出了不带帽的图1所示的注射器；
图3示出了带有一个被一个盖盖住的腔室的注射器。
具体实施方式
图1示出了一个具有一个本发明的腔室的优选注射器。该注射器属于这样的类型，即它因使用了挠性活塞杆而比传统的笔形注射器更短和更宽。这样的注射器的尺寸介于打火机和香烟盒之间，因此这种注射器易于随兜携带。由于使用大型安瓿且通过电子显示器加长了剂量设定机构而这要求至少笔的远端比较粗，所以笔形注射器随着时间的推移而丧失了其瘦长的设计形状。在这样的笔形注射器中，可以在注射器的较粗段内或者在剂量笔的加长段内设置一个腔室，但这样的加长段将无法肯定使笔形注射器的体积更大。因此，优选图1所示的那种新的盒形设计。
图1的注射器包括一个带刻度盘2的外壳1，可以根据所述刻度盘并通过转动一个把手3而直到把手3上的一个箭头4在刻度盘2上显示出所需剂量地设定注射剂量。随后通过一个注射钮6使上述药剂量经过一个装在一个针头座7内的针头5压射出去，所述针头座安装在一个在注射器上的针头接收件上。帽8盖住外壳上的腔室。
图2示出了拿掉了帽8的图1所示的注射器，其中草草地画出了一个针盒11，从而显示出了这种装有一根象安装在其针头座7内的针头5那样的针头的针盒11可以如何存放在腔室中。此外如此设计帽，即它的端面9形成了一个可以在注射时抵靠人体肌肤的抵靠面。
图3示出了一个与图1、2所示的注射器相应的注射器。在此注射器中，腔室与外壳完全成为一体且可以通过一个盖10触及该腔室。
如附图所示，腔室中的附件是一个针头，但也可以将其它类型的附件存放在腔室内如通常可被收集到一个耐用注射器中的电子仪器，但它们太昂贵了以致不能同可任意处理的注射器一起被丢弃。这样的电子仪器可以是各种计时器或设定用量电子读取装置或安瓿内剩余剂量电子读取装置。病人可能想随身携带的其它东西可能是说明书、换用药、药片、装卸针头的辅助工具等。
