Description

密闭配药给药装置 技术领域
本发明与配药给药装置有关;特别是指一种能构成密闭环境的密闭配药给药装置。
背景技术
现有的配药给药装置通常为一带有针头的针筒,由针头穿刺或伸入药液容器中吸取药液至针筒后,再对病患进行注射。随后,医护人员将带有针头的针筒盖上针头盖,再将针头从针筒移除,分类处理。然而,在实际操作上,由于需要进行注射的病例过多或是操作技巧不熟练,常常使得医护人员被针头扎伤,而使得医护人员受到感染的风险遽增。
若是所吸取的药液具有挥发性,则利用上述吸取药液至针筒的方式恐因配药过程中操作时间不当,导致所调配的药液浓度不正确,甚至造成病患极大的危害。除此之外,若具有挥发性的药液具有吸入性危害,则可能造成医护人员在调配药液时吸入过多的挥发性药液,对于医护人员的健康产生潜在的威胁。
另一方面,部分药液在使用前及时调配方能提供具体效用,而此类药液大多系以第一液体与第二液体依指定比例混合而成。依上述方式,将针头穿刺或伸入装有第一液体的容器中吸取第一液体至针筒后,再将同一针头穿刺或伸入装有第二液体的容器中吸取第二液体至针筒中,使第一液体及第二液体在针筒中进行混合,再对病患进行注射。如此一来,可能使残留在针头上的第一液体污染装有第二液体的容器,而使得装有第二液体的容器中的药物成分产生偏差,而无法继续使用,造成药物的浪费。
综上可知,目前亟需一种新颖的配药给药装置,用以改善现有配药给药装置所存在的诸多问题。
发明内容

抽注管12包括管壁及分隔壁,管壁围设成容置空间,分隔壁设置于容置空间内,且形成各自独立的第一空腔及一第二空腔。在本发明第一实施例中,管壁为第一管体12b,且具有所述容置空间,分隔壁围设成第二管体12a,第二管体12a系设置于第一管体12b的容置空间内,第二管体12a构成第一空腔,而第一管体12b与第二管体12a之间构成第二空腔162,如图4所示。
推拉杆组件14包括杆体142、活塞144、操作件146及封盖148。封盖148系固设且密封于抽注管12的第一端口。在本发明第一实施例中,封盖148的连接部1481与第一管体12b的连接部12b1彼此紧密连接,其中连接方式包括粘合或高频率熔接。杆体142穿设于封盖148的穿孔,杆体142的一端连接于操作件146,其另一端连接于活塞144。在本发明第一实施例中,推拉杆组件14包括密封环147套设于杆体142,且设置于封盖148的穿孔处,如图8所示。活塞144气密地设置于第一空腔中,且可受操作地在第一空腔内移动。活塞144将第一空腔分隔为第一区域及第二区域,第二区域与第一区域相比较更靠近抽注管12的第一端口。其中,第一区域与第二区域在抽注管12内互不连通,第二区域在第一端口处与第二空腔连通。在本发明第一实施例中,第一管体12b具有第一端口,所述封盖系固设且密封于所述第一管体12b的所述第一端口,但未密封于所述第二管体12a,使所述第一空腔的所述第二区域在所述第一端口处与所述第二空腔162连通。
连接口16、16’固接于抽注管12、12’的第二端口,第二端口系相背于第一端口。连接口16、16’包括第一通道122、第二通道124及至少一个软塞166。第一通道122系连通于第一空腔,第二通道124系连通于第二空腔162。软塞166系气密地固设于第一通道122及第二通道124的一端,使密闭配药给药装置10构成密闭环境。
当密闭配药给药装置10连接于药液容器(未图示)时,软塞166可受操作地被突破,而使第一通道122及第二通道124借由药液容器彼此连通。当推拉杆组件14的操作件146受外力拉动,且经由杆体142带动活塞144往抽注管12的第一端口移动时,第一空腔的第一区域变大以从药液容器经由第一通道122抽吸药液至第一区域中,同时第二区域变小,使第二区域中的空气经由第二空腔162及第二通道124排出至药液容器中,使密闭配药给药装置10与药液容器构成另一密闭环境。
在本发明第一实施例中,连接口16包括至少一个柱状物121,柱状物121固接于抽注管12的第二端口。第一通道122及第二通道124系设置于柱状物121内,且软塞166系气密地固设于柱状物121的远离抽注管12的一端,如图5所示。在图5中,软塞166具有针孔166a、166b,针孔166a系对应连通于第一通道122,而针孔166b系对应连通于第二通道124。
柱状物121系固接于抽注管12中第二管体12a的第二端口处,柱状物12中的第一通道122系对应于第一空腔,使第一通道122与第一空腔连通。连接口16包括至少一个套体161,用以容置柱状物121,且软塞166系气密地夹设于柱状物121及套体161之间。
在本发明第一实施例中,柱状物121具有彼此相反的第一侧及第二侧,第一通道122系靠近第一侧,而第二通道124系靠近第二侧。套体161具有彼此相反的第一槽边及第二槽边,柱状物121的第一侧系对应设置于套体161的第一槽边,而柱状物121的第二侧系对应设置于套体161的第二槽边。由于第一侧的外径系不同于第二侧的外径,且第一槽边的内径系不同于第二槽边的内径,因此柱状物121的第一侧无法设置于套体161的第二槽边,且柱状物121的第二侧无法设置于套体161的第一槽边。
请参图6,柱状物包括第一柱状物121a及第二柱状物121b,第一通道122系设置于第一 柱状物121a内,而第二通道124系设置于第二柱状物121b内;且软塞166’系气密地固设于第一柱状物121a及第二柱状物121b远离抽注管12’的一端。在本发明第二实施例中,软塞166’包括第一软塞及第二软塞;第一软塞系气密地固设于第一柱状物121a远离抽注管12’的一端,且第二软塞系气密地固设于第二柱状物121b远离抽注管12’的一端。第一柱状物121a及第二柱状物121b系固接于抽注管12’中第二管体12a的第二端口处,第一柱状物121a中的第一通道122系对应于第一空腔,使第一通道122与第一空腔连通。连接口16’包括至少一个套体161,用以容置第一柱状物121a及第二柱状物121b,且软塞166’系气密地夹设于第一柱状物121a及第二柱状物121b与套体161之间。套体161具有彼此相反的第一槽边及第二槽边,第一柱状物121a系对应设置于套体161的第一槽边,而第二柱状物121b系对应设置于套体161的第二槽边。进一步来说,由于第一柱状物121a的外径系不同于第二柱状物121b的外径,且第一槽边的内径系不同于第二槽边的内径,因此第一柱状物121a无法设置于套体161的第二槽边,且第二柱状物121b无法设置于套体161的第一槽边。
在本发明第二实施例中,套体包括第一套体161a及第二套体161b,且软塞166’包括第一软塞及第二软塞,第一套体161a用以容置第一柱状物121a,而第二套体161b用以容置第二柱状物121b,第一软塞系气密地夹设于第一柱状物121a及第一套体161a之间,第二软塞系气密地夹设于第二柱状物121b及第二套体161b之间,如图6所示。由于第一柱状物121a的外径系不同于第二柱状物121b的外径,且第一套体161a的内径系不同于第二套体161b的内径,因此第一柱状物121a无法设置于第二套体161b内,且第二柱状物121b无法设置于第一套体161a内。

当密闭配药给药装置30连接于药液容器(未图示)时,软塞366可受操作地被突破,而使第一通道322及第二通道324借由药液容器彼此连通。当推拉杆组件34的操作件346受外力拉动,且经由杆体342带动活塞344往抽注管32的第一端口移动时,第一空腔32a的第一区域变大以从药液容器经由第一通道322抽吸药液至第一区域中,同时第二区域变小,使第二区域中的空气经由第二空腔32b及第二通道344排出至药液容器中,使密闭配药给药装置30与药液容器构成另一个密闭环境。

值得一提的是,当连接器20解除与连接口16的连接时,外弹性体23a及内弹性体23b受本身的弹性力而沿中空柱22的长方向往远离第二端部24的方向伸展,且内弹性体23b辅助外弹性体23a持续接触连接口16,直到第一针头21a及第二针头21b再度被外弹性体23a包覆,使第一针头21a及第二针头21b不对外裸露,以确保使用者不会因接触到第一针头21a及第二针头21b而受伤。

本发明第六实施例之连接器60可拆卸地连接于连接口56。连接器60包括彼此相背的第一端部62及第二端部64,第一端部62包括同向相邻排列的第一针头61a及第二针头61b。当连接器60的第一端部62连接于连接口56时,第一针头61a的顶部凹面61a1顶推于软塞568a及第二针头61b的顶部凹面61b1顶推于软塞568b,且第一针头61a系对应连通于第一通道522,而第二针头61b系对应连通于第二通道524中,如图33所示。连接器60的第二端部64系可拆卸地连接于药液容器,且第二端部64系连通于第一端部62的第一针头61a。在本发明第六实施例中,当连接器60的第一端部62连接于连接口56时,第一针头61a的顶部凹面61a1顶推于软塞568a及第二针头61b的顶部凹面61b1顶推于软塞568b,且软塞568a、568b顶推弹性体565,使弹性体565往抽注管52的第二端口被压缩。
在图32中,第一端部62包括中空柱62及弹性件63,第一针头61a、第二针头61b及弹性件63系设置于中空柱62内。当连接器60未连接于连接口56时,弹性件63大致包覆第一针头61a及第二针头61b,借以防止残留在第一针头61a及第二针头61b的药液及/或气体向外泄漏。在本发明第六实施例中,中空柱62的长方向与第一针头61a及第二针头61b的长方向平行,当连接器60连接于连接口56时,弹性件63可受操作地沿中空柱62的长方向往靠近第二端部64的方向被压缩,使第一针头61a及第二针头61b凸出弹性件63,且分别顶推于软塞568a、568b,如图33所示。
此时,连接器60的第二端部64系可拆卸地连接于药液容器,而使第一通道522及第二通道524借由药液容器彼此连通。当推拉杆组件54的操作件546受外力拉动,且经由杆体542带动活塞544往抽注管52的第一端口移动时,第一空腔的第一区域变大以从药液容器经由第一通道522抽吸药液至第一区域中,同时第二区域变小,使第二区域中的空气经由第二空腔562及第二通道524排出至药液容器中,使密闭配药给药装置50与药液容器构成另一密闭环境。
本发明所提供的密闭配药给药装置不具有向外暴露的针头,因此可避免医护人员发生被针头扎伤的问题,进而降低医疗过程因器材所产生的感染风险。此外,本发明所提供的密闭配药给药装置可与药液容器形成封闭环境,因此可避免吸取挥发性药液所产生的浓度偏差,亦可避免医护人员吸入挥发性药液而对健康产生潜在的威胁。再一方面,本发明所提供的密闭配药给药装置可避免使用同一针头吸取不同药液的机会,进而避免不同药液之间彼此污染,而造成药物浪费。
以上所述仅为本发明优选可行实施例而已,举凡应用本发明说明书及申请专利范围所为之等效变化,理应包含在本发明之专利范围内。
