技术领域
本发明涉及一种过滤装置及包括其的过滤输液容器。
背景技术
在临床输液时，带有过滤膜的过滤装置在使用前，过滤膜要保持完整性才能达到最佳过滤效果，也就是说过滤膜不仅要是未被破坏的状态，同时要在患者使用时才第一次与输液液体接触。
但是，在现有技术中，由于在出厂前预处理的不同的特定灭菌过程(如蒸汽灭菌等诸多医药行业的灭菌方式)中容易有蒸汽及其他物质接触过滤膜，从而改变过滤膜的预期过滤效果，降低了过滤膜的有效性。
此外，在现有技术中，也有采用开关打开液体通道的方案，但是这种方案会导致不能保证输液液体的密封性，从而也会改变过滤膜的预期过滤效果，降低了过滤膜的有效性。
发明内容
本发明要解决的技术问题是为了克服现有技术中在患者使用前有蒸汽及其他物质接触过滤膜或者不能保证输液液体的密封性，从而改变过滤膜的预期过滤效果，降低了过滤膜的有效性的缺陷，提供一种过滤装置及包括其的过滤输液容器。

第二部件40与第一部件20连接，第二部件40设有内腔42，内腔42与第一容置腔213连通，流道41设于第二部件40内，且与内腔42远离第一容置腔213的一端相连通。
第二部件40包括安装座43，安装座43设有安装腔431，安装腔431的中心轴线垂直于流道41的中心轴线。阻隔件60设于流道41和安装腔431的连接处，且阻隔件60所在的平面与流道41的轴向形成有夹角。在本实施例中，阻隔件60可以和第二部件40一体成型，在生产过程中，可以一起注塑生产，从而保证输液液体的密封性。
穿刺插件50包括相连接的穿刺插件的头部51和穿刺插件的杆部52，穿刺插件的杆 部52插设于安装腔431。穿刺插件的杆部52靠近阻隔件60的一端设有尖端521，阻隔件60设有与尖端521相对应的导向槽61。这样，由于阻隔件60所在的平面与流道41的轴向形成有夹角，也就是说阻隔件60呈倾斜状，通过对应尖端521设置导向槽61，使尖端521有着力点，更容易刺破阻隔件60。
尖端521设有卡位槽5211，导向槽61与卡位槽5211相对应的位置设有卡位凸起612，卡位槽5211与卡位凸起612配合用于限制穿刺插件50的移动。这样，通过尖端521的卡位槽5211与卡位凸起612的配合起到对尖端521运动方向的限位，以此达到精准穿刺的作用。
穿刺插件的头部51中面向流道41的一侧设有限位槽512，安装座的侧壁432的外表面设有与限位槽512对应的限位凸起4321，限位槽512与限位凸起4321配合用于限制穿刺插件50的移动。这样，通过穿刺插件的头部51的限位槽512和安装座43的限位凸起4321配合，以此达到精准穿刺的作用。
本发明还提供一种过滤输液容器2，其特点在于，其包括如上的过滤装置，过滤输液容器2还包括一输液容器2，过滤装置连接在输液容器2上，且流道41的一端通向输液容器2，另一端通向主体1。
实施例4
如图13-图15所示，本实施例的过滤装置的整体结构基本和实施例3中的结构相同，其不同的地方在于，穿刺件为穿刺钉90，穿刺钉90的中心轴线与流道41的中心轴线重合，穿刺钉90沿流道41的中心轴线的方向直线运动。
在本实施例中，主体1还包括支架80，支架80位于第二部件40的内腔42内，支架80的一端套设于流道41的外壁外，支架80的另一端抵接于过滤膜30。在本实施例中，主体1还包括卡环72，卡环72套设于第一部件20的一端卡扣于第二部件40相对应的一端外，使第一部件20和第二部件40紧密连接。在图14和图15中未标示固定件71，但具体实施例中，也可以设置固定件71。
穿刺钉90包括相连接的穿刺钉的头部91和穿刺钉的杆部92，穿刺钉的头部91的直径大于穿刺钉的杆部92的直径。穿刺钉的杆部92远离穿刺钉的头部91的一端设有导液槽921，且依次穿设于第二容置腔223、顶板222、过滤膜30、支架80、流道41。穿刺钉的头部91卡设于第二容置腔223内。
穿刺钉的杆部92外套设有密封垫93，密封垫93用于密封穿刺钉90与过滤膜30之间的间隙224。这样可以保证所有的输液液体不会通过穿刺钉90与过滤膜30之间的间隙224，保证输液液体均通过过滤膜30再进入第一部件20；同时，也保证输液液体不会直 接进入第二容置腔223，而是先经过第一容置腔213，再通过间隙224进入第二容置腔223，也就是输液液体如图15中所示的箭头方向流动。
在其他实施例中，也可以设置穿刺件为其他结构，并不仅限于本实施例中的穿刺钉90。
虽然以上描述了本发明的具体实施方式，但是本领域的技术人员应当理解，这些仅是举例说明，本发明的保护范围是由所附权利要求书限定的。本领域的技术人员在不背离本发明的原理和实质的前提下，可以对这些实施方式做出多种变更或修改，但这些变更和修改均落入本发明的保护范围。
