背景技术
目前，一次性使用输液器是临床输液必备的医疗器具，其一般从上至下依次包括穿刺器、输液管、点滴筒、流速调节器、鲁尔接头、输液针。输液过程中，一般需要先使用注射器、配药连接器向葡萄糖瓶、氯化钠瓶等输液瓶中注射药物，进行配药，配药后将输液器的穿刺器插入输液瓶的胶塞中，然后再输液，输液瓶的胶塞需要多次穿刺。
发明内容
本发明的目的在于提供一种带配药连接器的精密过滤输液器，配药时将配药连接器与输液瓶连接，注射器与配药连接器连接配药，配药后，配药连接器直接与输液管连接进行输液，使用方便。
为实现上述目的，本发明采用了下述技术方案。一种带配药连接器的精密过滤输液器，包括配药连接器和输液器本体，其特征是，配药连接器的两端分别设有连接机构，输液器本体的进液端设有对接机构，配药连接器的其中一个连接机构与输液器本体的进液端的对接机构连接配合。
进一步优选，所述连接机构是穿刺器、穿刺针或插接头。
进一步优选，所述对接机构是穿刺器插头或插接孔。
进一步优选，配药连接器的中部为过滤器，过滤器上端连接穿刺针或穿刺器，过滤器下端连接穿刺针、穿刺器或插接头，过滤器内设置一层竖过滤膜，竖过滤膜将过滤器11内腔分成左腔和右腔，左腔连通穿刺针或穿刺器，右腔连接穿刺针、穿刺器或插接头。
进一步优选，过滤器上设置自毁机构，自毁机构是设置在过滤器侧壁的折断杆。
进一步优选，输液器本体包括进气管、空气过滤器、滴管、滴斗、流量调节器、外圆锥接头、外圆锥接头保护套，滴管上设有滴斗和流量调节器，滴管的进液端设置穿刺器插头，滴管的进液端还通过旁路连接进气管，进气管连接空气过滤器，滴管的出液端设有外圆锥接头，外圆锥接头盖有外圆锥接头保护套，外圆锥接头用于连接带输液针的输液管。
本发明的有益效果：配药连接器配药后可直接与输液器连接，用于输液，使用方便；配药连接器内设过滤器，可直接过滤，输液器本体里面的过滤器可省去，或者保留输液器内的过滤装置，可二次过滤药液，配药连接器设置了自毁机构，使用后可直接毁坏，避免重复使用。

具体实施方式
下面将结合附图和实施例对本发明中的技术方案进行具体、清楚、完整地描述。
参照图1，带配药连接器的精密过滤输液器包括配药连接器1、穿刺器插头2、进气管3、空气过滤器4、滴管5、滴斗6、流量调节器7、外圆锥接头8、外圆锥接头保护套9，滴管5上设有滴斗6和流量调节器7，滴管5的进液端设置穿刺器插头2，配药连接器1的两端设有穿刺器，配药连接器1其中一端的穿刺器插入穿刺器插头2中实现配药连接器1与滴管5连接，配药连接器1另一端的穿刺器插入输液瓶。滴管5的进液端还通过旁路连接进气管3，进气管3连接空气过滤器4，滴管5的出液端设有外圆锥接头8，外圆锥接头8盖有外圆锥接头保护套9，外圆锥接头8用于连接带输液针的输液管。
图1中的配药连接器1两端均为穿刺器。配药连接器1也可以一端为与输液瓶连接穿刺针12，另一端为与滴管5进液端匹配的插接头13，如图2和图3所示；滴管5进液端对应的设置插接孔，并设置插接孔保护盖，起到防尘作用。
参照图2和图3，配药连接器1的中部为过滤器11，过滤器11上端连接穿刺针12，过滤器11下端连接插接头13，过滤器11为正六边形，方便配药支撑药瓶，稳定性更好；过滤器11内设置一层竖过滤膜16，竖过滤膜16将过滤器11内腔分成左腔17和右腔18，左腔17连通穿刺针12，右腔18连接插接头13。
为了防止配药连接器1重复使用，过滤器11上设置自毁机构14，自毁机构14是设置在过滤器11侧壁的折断杆，使用完毕后，用手握住过滤器11，大母指掰折断杆，使折断杆和过滤器11侧壁的连接处破坏，即可使配药连接器1无法使用。当然自毁机构14也可以使用其他任意可破坏过滤器11的结构或机构。
本发明中，滴斗6内可设置精密过滤膜进行二次过滤。
本发明使用时，通过配药连接器1配药，使药物配制于输液瓶中，配药连接器1一端通过穿刺器或穿刺针连接输液瓶，使配药连接器另一端的穿刺器、穿刺针或插接头13连接滴管5的进液端，之后再按常规方法使用输液器即可进行输液。
上面所述的实施例仅仅是对本发明的优选实施方式进行描述，并非对本发明的构思和范围进行限定。在不脱离本发明设计构思的前提下，本领域普通人员对本发明的技术方案做出的各种变型和改进，均应落入到本发明的保护范围，本发明请求保护的技术内容，已经全部记载在权利要求书中。
