具体实施方式
下面通过实施例的方式进一步说明本发明，但并不因此将本发明限制在所述的实施例范围之中。
请结合图1-图3予以理解，本实施案例提供一种过滤装置1，其包括：密封部件10、第一部件20、过滤膜30、第二部件40和执行件50。第一部件20的一端卡扣于第二部件40相对应的一端，且第一部件20与第二部件40密封连接。过滤膜30夹设于第一部件20与第二部件40之间。第一部件20一体成型。
第一部件20包括：外壳21和内壳22。外壳21的第一侧壁211与底板212围设形成有一第一容置腔213。内壳22的一端穿设于第一容置腔213内，内壳22的另一端穿设于外壳21的底板212且位于外壳21外，底板212密 封连接于内壳22的第二侧壁221的外表面，第二侧壁221与顶板222围设形成有一第二容置腔223，内壳22穿设于第一容置腔213内的第二侧壁221设有四条间隙224，四条间隙224均连通第一容置腔213与第二容置腔223。四条间隙224沿第二容置腔223周向间隔等距分布。在其他可替代实施例中，间隙224的数量也可以是两个、三个或者其他数量。
内壳22的第二侧壁221包括相连接的第一部分2211和第二部分2212，第一部分2211的厚度小于第二部分2212的厚度；第一部分2211位于第一容置腔213内，且第一部分2211设有前述间隙224；第二部分2212位于述外壳21外，外壳21的底板212密封连接于第二部分2212靠近第一部分2211的一端的外表面。
密封部件10卡设于内壳22的另一端，且密封部件10用于密封第二容置腔223。密封部件10的材质为橡胶。在本实施例中，密封部件10外还套设有固定件70，固定件70的一端沿周向卡设于内壳22靠近密封部件10的一端外。固定件70用于将密封部件10更好的固定于内壳22的一端。
第二部件40包括流道41。执行件50用于关闭或打开流道41。执行件50的中心轴线垂直于流道41的中心轴线，执行件50沿垂直于流道41的中心轴线的方向直线运动的同时绕执行件50的中心轴线旋转运动。执行件50包括相连接的头部51和杆部52，头部51的直径大于杆部52的直径。执行件50的头部51旋转连接于第二部件40。执行件50的杆部52插设于流道41，且执行件50的杆部52的外表面套设有密封套53。这样，通过密封套53的这种密封方式，使过滤装置1经过特定灭菌过程(如蒸汽灭菌等诸多医药行业的灭菌方式)之后继续保持良好的密封性，也就是使过滤膜30与输液液体在患者使用前始终处于不同的密闭空间，而保持过滤膜的最佳的完整性，同时，使过滤装置不会产生漏液的情况，在运输过程中执行件也不会松动。在本实施例中，密封套53与杆部52螺纹连接。密封套53的材质为橡胶。
第二部件40还包括安装座43。安装座设有内腔431，执行件50的杆部52插设于内腔431，内腔431的中心轴线垂直于流道41的中心轴线。
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中面向限位槽512的一端插设于限位槽512，限位槽512与安装座的侧壁432配合用于限制执行件50的移动。
在本实施例中，安装座的侧壁432的外表面设有旋转凸起4321，限位槽512的内表面设有与旋转凸起4321对应的旋转凹槽513，旋转凸起4321与旋转凹槽513配合限制执行件50的旋转运动轨迹。这样，通过设置相配合的旋转凸起4321与旋转凹槽513，使执行件50的移动更为平稳，能够更为稳定地控制执行件50关闭或打开流道的移动速度和距离；同时相配合的旋转凸起4321与旋转凹槽513可以限定执行件50在受到压力下直接向远离安装座43的方向运动，从而避免打开流道41。
具体来说，执行件50的密封套53在执行件50关闭流道41时，同时此时在蒸汽消毒状态，上方药液因为升温膨胀的压力就会分摊在整个密封套53上，这时的由于密封套53起到了密封流道41的作用，在流道41的末端会形成一定空间的死腔(即空气无法正常排出)，同理在蒸汽灭菌状态，由于温度(蒸汽灭菌温度达到121℃)升高会导致这部分的死腔中的气体膨胀，从而推动执行件50向远离安装座43的方向运动，也就是打开流道41方向运动，这样会形成一种潜在的风险，即消毒时流道41会被打开，药液会渗透过滤膜导致过滤膜失效，而通过执行件的旋转凹槽513和安装座的旋转凸起4321的螺纹配合可以抵消来自空气膨胀的力，从而保护过滤膜在消毒时不被浸湿。
安装座的内腔431的内壁沿径向向内腔431的中心轴线方向延伸有限位台阶4311，杆部52的外壁沿径向向安装座43方向延伸有限位凸起521，限位凸起521抵靠于限位台阶4311，且限位凸起521与限位台阶4311配合用于限制执行件50向远离安装座43的方向移动。这样，通过设置相配合的限 位凸起521与限位台阶4311，限定了执行件50的移动位置，并使执行件50不会从安装座43上脱落下来，保证了使用安全。
过滤装置1还包括一流路60，流路60依次通过流道41、过滤膜30、第一容置腔213、间隙224、第二容置腔223。
本发明的工作原理：当输液液体沿流路到达第一容置腔时，输液液体的水平面逐渐上涨，液面到达指定的高度后再通过间隙进入第二容置腔后再下液，这样能够防止输液液体从过滤膜过滤后呈现水滴状直接滴入插瓶针孔中而形成连续的气栓，从而能够更好地控制输液过程。同时，通过设置内壳的结构，在插瓶针插入第二容置腔时，由于内壳的顶板的阻挡，可以防止插瓶针直接刺破过滤膜，提高了操作过程中的安全性。另外，本技术方案中的间隙还具有防止气泡进入第二容置腔，保证输液液体的安全可靠性。
本实施例还提供一种过滤输液容器，其包括如上的过滤装置1，所述过滤输液容器还包括输液容器2，过滤装置1连接在输液容器2上，且流路60的一端通向输液容器2，另一端通向过滤膜30。
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。
