Description

一种自动吸药、注射连接装置
技术领域
[0001]本发明涉及无菌医疗器械领域,尤其涉及一种自动吸药、注射连接装置。
背景技术
[0002]注射器产品附件中包含的连接管是用于连接注射器和穿刺针。在使用中,必须用专用的吸药器从药瓶或袋式包装中将药剂吸入注射器,然后断开吸药器和注射器的连接,另外将附件连接管接到注射器上。在操作过程,操作顺序麻烦,且在断开吸药器和注射器连接时药剂会暴露于空气中带来污染的风险。
发明内容
[0003]为解决上述技术问题,本发明提出了一种自动吸药、注射连接装置,包括可控流向三通阀、与所述可控流向三通阀上连接有注射器、药液瓶;所述可控流向三通阀包括三通管,所述三通管包括主管和两个支管,两个所述支管与所述主管连通,所述主管垂直连接于所述支管上;两个所述支管上分别设置有流动方向相同的单向阀,所述单向阀包括阀体,所述阀体内设有软性密封片、锥形块,所述锥形块顶于所述软性密封片。
[0004]优选的,所述软性密封片为橡胶片。
[0005]优选的,所述注射器通过第一连接管与所述主管连接。
[0006]优选的,两个所述支管上分别通过第二连接管连接药液瓶和第三连接管连接用户端。
[0007]优选的,所述第二连接管上连接有插瓶针并插入所述药液瓶。
[0008]本发明提出的自动吸药、注射连接装置有以下有益效果:1、能大大节省操作时间和步骤,减轻了用户的劳动强度,有效避免发生误操作的风险;2、药液在密闭空间传递,有效避免药液暴露在空气中造成污染的风险。
附图说明
[0009]为了更清楚地说明本发明实施例中的技术方案,下面将对实施例描述中所需要使用的附图作简单地介绍。
[0010]图1为本发明的结构示意图;
[0011]图2为本发明的单向阀的结构示意图;
[0012] 其中,1-可控流向三通阀,2-注射器,3-药液瓶,4-主管,5-支管,6_单向阀,7_阀体,8-锥形块,9-软性密封片,I O-第一连接管,11-第二连接管,12-第三连接管,13-插瓶针,14-用户端。
具体实施方式
[0013]下面将结合本发明实施例中的附图,对本发明实施例中的技术方案进行清楚、完整地描述。
[0014]如图1、图2所示,本发明提出了一种自动吸药、注射连接装置,包括可控流向三通阀1、与所述可控流向三通阀I上连接有注射器2、药液瓶3;所述可控流向三通阀I包括三通管,所述三通管包括主管4和两个支管5,两个所述支管5与所述主管4连通,所述主管4垂直连接于所述支管5上;
[0015]两个所述支管5上分别设置有流动方向相同的单向阀6,所述单向阀6包括阀体7,所述阀体7内设有软性密封片9、锥形块8,所述锥形块8顶于所述软性密封片9,其中,所述软性密封片9与阀体7内壁密封,单向阀6的工作原理是在每个阀体7里有一块橡胶片,被锥形或者伞状顶尖固定在单向阀6中,当一侧液体通过,液体的压力将橡胶片压成伞状,液体可通过周边留出的空隙通过,达到导通的效果;而当反方向液体流过,液体压力将橡胶片压在出口处,使得出口被堵住,而液体则无法流出。
[0016]优选的,所述软性密封片9为橡胶片,也可以是硅胶片等软性材料。
[0017]优选的,所述注射器2通过第一连接管10与所述主管4连接。
[0018]优选的,两个所述支管5上分别通过第二连接管11连接药液瓶3和第三连接管12连接用户端14。
[0019]优选的,所述第二连接管11上连接有插瓶针13并插入所述药液瓶3。
[0020]本发明的工作方式是:在两个单向阀6共同作用下,当操作注射器2推杆前进后退时,管路内部作用到每个单向阀6上的压力相反,其中一个单向阀6呈伞状变形,此路导通;另一个单向阀6被压在出口并堵住使得此路封闭,在任何一个注射器2动作中,保证两个阀门只有其中一个导通,可实现药液在抽吸和注射不同阶段的自动控制。
[0021]如图1所示的实施例为注射器2后退,将药液瓶3的药液通过插瓶针13进入注射器2,当注射器2推进时,将注射器2内的药液推进至用户端14,由于单向阀6的作用不会进去药液瓶3,能大大节省操作时间和步骤,减轻了用户的劳动强度,有效避免发生误操作的风险;药液在密闭空间传递,有效避免药液暴露在空气中造成污染的风险。
[0022]对实施例的多种修改对本领域的专业技术人员来说将是显而易见的,本文中所定义的一般原理可以在不脱离本发明的精神或范围的情况下,在其它实施例中实现。因此,本发明将不会被限制于本文所示的这些实施例,而是要符合与本文所公开的原理和新颖特点相一致的最宽的范围。
