Description
技术领域
本发明涉及流体转移,并且更具体地,涉及用于将流体从第一容器转移至填充有流体的第二容器的方法和设备。
背景技术
在本领域中,将液体或流体从一个容器转移到另一个容器是公知的,并且许多装置被用于促进该转移。然而,在医疗领域中,在这样做时必须非常小心,同时要符合无菌等所有要求。当需要将液体从第一容器转移到第二容器中,并且其中第二容器已经包含液体时,会出现一个具体问题。第二容器已经充满液体,并且这种容器将通常包括注射器主体,该注射器主体是一端具有柱塞而在第二端具有挡块或密封构件的玻璃圆筒。可选地,可以连接针状物。通常,主体已经与柱塞一起被消毒,而由于如果较多的流体被置于容器中将发生允许柱塞移动到非消毒区域中是不可接受的过程。如本文所用,术语“小瓶”是指具有可刺穿的塞子的玻璃容器,而装填瓶是具有可刺穿的塞子和柱塞的玻璃容器。
在某些情况下需要在容器之间转移这种流体。这种情况的一个示例是在用液体来冷冻肉体的情况下(使肉体对疼痛不敏感)。用于冷冻的典型注射要求待注射的液体为酸性。液体的酸性性质随后引起患者疼痛。因此,期望使用诸如碳酸氢钠化合物来中和或缓冲液体。
发明内容
根据本发明,提供了一种用于组合两种液体的装置和方法,由此允许将第一液体的一部分排放到装置的储存部分中。

具体实施方式
更详细地参照附图并通过附图标记示出了一种转移系统,该转移系统一般由附图标记10表示,并适于与一般由附图标记12表示的小瓶一起使用。
小瓶12具有主体14,主体颈部由隔膜16密封,隔膜之上有盖18。药物20包含在主体14内,并且通常包括干成分,但也可使用流体。
转移系统10包括外壳24和圆形侧壁26。在圆形侧壁26上靠近其底部有突出部28。在其上端设有鲁尔连接器30。内壁32安装有本质上中空并具有穿刺端36的针状物34。如前所述,针状物34可以是长刺针。
安装在外壳24内部的是一个可移动构件40,可移动构件40具有顶壁42,顶壁中心有允许针状物34通过的孔44。从顶壁42向下延伸的是第一支脚46和第二支脚48。第一支脚46在其底部有向外延伸的凸缘50,而第二支脚48也具有向外延伸的凸缘52。
提供盖56以容纳转移系统10。盖56具有带凹槽58的侧壁57,该凹槽适于与突出部28接合以将转移系统10保持在适当位置。侧壁57在其底部设有向外延伸的凸缘60。凸缘60被设计成接收可剥离的密封带62,以便提供气密密封的包装。
本发明的输送系统优选地与具有注射器主体66和安装在其中的柱塞68的装填瓶一起使用。柱塞杆70被设计成可与柱塞68螺纹啮合。注射器主体66包括止挡72,以便使用者能用手适当地握住。在其前端,注射器主体66包括鲁尔连接器74。尽管可以使用任何所需的流体,但通常注射器主体66充满稀释剂76。
如图8和图9所示,柱塞杆70连接至柱塞68,然后迫使稀释剂76进入小瓶主体14中,如图10所示。然后药物和稀释剂可以被混合,并且如图11所示,组件被翻转。然后,混合物80被抽吸回注射器主体66中。然后当针状物组件连接至鲁尔连接器74时,混合物80准备好注射。
在图17A到图17H的实施例中,应当注意,外壳24在侧壁26上设置有一对孔86。在该实施例中,还提供了额外的一对支脚87,每个支脚具有形成在其外表面上的按钮88。在该实施例中,当可移动构件40向上移动时,按钮88在孔86中接合。
在壁26的内表面上设置有肋90,该肋具有形成在其中的凹槽92。因此,当随着小瓶12被抽出在按钮86上施加压力时,可移动构件40将向下移动,直到顶壁42与凹槽92接合。这将可移动构件40保持在适当位置以便进一步使用。
在图18至图19D的实施例中,可以注意到,顶壁42设有突出部96和锁定闩98。在内部设有肋100和倾斜的侧壁部分102。这种布置使得在可移动构件40向上移动时,突出部96与倾斜侧壁102接合,以旋转可移动部件40。在退出时,锁定闩98与肋100接合,以便防止转移构件的进一步使用。
如图20A和图20B所示,转移组件将包括如本文先前所述的转移装置202。盖204安装在转移装置202上,并施加可移除的密封件206。
该转移装置包括针状物组件,该针状物组件一般由附图标记208表示,并因此在图21中可见。主体部分210具有延伸通过其中的针状物212。针状物212是金属材料的,并且被主体部分210包覆模制。针状物212包括穿刺尖端214和延伸通过其中的针状物通道216。塑料刺针218形成为针状物212的一部分。塑料刺针具有穿刺尖端220,该穿刺尖端具有形成于其中的刺针排出通道222。如图中所示,针状物通道216和刺针排出通道222并排设置,而针状物212的一部分形成刺针排出通道222的一个壁。针状物穿刺尖端214和刺针穿刺尖端220二者均被倾斜以提供最佳刺穿能力。如本领域所已知的,两个尖端均是锋利的。
应当注意,针状物通道216比通向刺针排出通道222的开口向下延伸一点。在使用中,刺针通道216用于将药物或液体转移到另一容器中,而刺针排出通道222允许气体或液体从其中流出。当从一个容器转移到另一个容器时,第二容器中的液体将通过刺针排出通道222排出,以允许压力的均等,并使得经针状物通道216转移的液体平稳地流入第二容器中。
现在参照图22至图31B所示的实施例,示出了一般由附图标记410表示的注射器。
流体传输装置410包括一般由附图标记412表示的外壳、一般由附图标记414表示的刺针接口、一般由附图标记416表示的装填瓶以及一般由附图标记418表示的基座构件。
外壳412由略长椭圆形的壁422限定。外壳412具有开口顶部424和开口底部426。一对下槽428彼此径向相对地设置。一对径向相对的上槽430和一对径向相对的中间槽432位于壁422的上部。壁422还具有一对以径向相对的方式形成的圆孔438。在壁422的内部,提供了径向相对的下肋436。
基座构件418也具有带侧壁440和侧片442的整体椭圆形配置,侧片442径向相对。在每个侧片442上,存在向外延伸的突出部444。基座构件418还包括底壁446。在侧壁440的内部,设置有角肋448,其中角肋位于基座构件418的拐角附近。
柱塞杆50从底壁446向上延伸。提供一对导向构件452,柱塞杆450的每侧上各一个。
针状物接口414包括第一侧壁456和第二侧壁458。每个侧壁456、458包括相对平坦的外边缘和平坦部分之间的弓形内部。上凸片460从侧壁456向上延伸,而上凸片462从侧壁58延伸。上凸片460上设置有突出部464,而上凸片462上设置有突出部466。针状物接口414还包括相对的端壁468、470。设置中间壁472。中间壁472没有完全延伸跨过端壁468、470与侧壁456、458之间,从而在其中留下通道478。上部针状物474安装在中间壁472一侧,而下部针状物476安装在中间壁472的另一侧。
如附图中所示,第一装填瓶416放置在基部构件418内,使得柱塞488安置在柱塞杆450上,同时可刺穿盖490面向上。随后,外壳412具有放置在其中的第一装填瓶416和插入的针状物接口414,使得上凸片460、462的突出部464、466限制移动以防止过度移动。对外壳412和第一装填瓶416上的向下压力导致对可刺穿盖484和490的刺穿,如图29、30A和30B所示。这将导致第一装填瓶416内的液体转移到第二装填瓶480。如前所述,由于排出针状物,允许过量液体流过通道478。
应当理解,上述实施例仅用于说明的目的,并且在不背离本发明的精神和范围的情况下可以对其进行改变和修改。
