Description

一种精密过滤输液容器 技术领域
本发明涉及医药包装材料领域，特别是涉及一种精密过滤输液容器。
背景技术
在传统治疗手段中，输液治疗是其中一个重要的方式。但输液中存在大量不溶性微粒，其中因药物溶解不充分导致的不溶性微粒占据主要部分。
传统输液容器只提供盛存药液的作用，不能将药液中不溶性微粒过滤。
现阶段临床以应用过滤输液器来解决输液中的微粒问题，普通的过滤输液器因过滤膜与输液容器有一定的高度差，液体压力较大，导致部份临界滤孔大小的微粒亦会通过过滤膜进入人体。临床上亦会出现同一根输液器上需进行多组药物、长时间输注的情况。在非热原输液反应中，药液中微粒数的超标是引起反应的重要因素，而输液过程时使用的输液器，由于较长时间的使用使其滤器的过滤作用大大减弱或丧失，甚至成为一个增加微粒的污染源。同时，不同的药物颗粒会停留在滤网上，增加相互反应的风险。
有应用过滤装置的输液容器，因滤液腔内气体不能在输液前排出，导致滤液腔内气体会随输液穿刺针进入输液管道，不符合临床安全应用要求。
现行精密过滤输液容器需将各个组件多次粘接、组装，增加工序，增加成本，增加病人医疗费用。

图1是本发明中第一实施例整体结构示意图；
图2是本发明中第二实施例整体结构示意图；
图3是本发明中第二实施例经过滤腔整体结构水平示意图；

具体实施方式
参照图1～图5，本发明为一种精密过滤输液容器，包括容器本体1及通过密封装置6与容器本体1分隔开来的密封腔体2；所述密封腔体2内设有药液过滤装置、排气装置和密闭胶塞3；
所述药液过滤装置包括至少一道药液过滤膜4；
至少一道所述药液过滤膜4围绕与排气装置形成滤液腔5，或者所述排气装置和药液过滤膜4与密闭胶塞3间的密闭空间形成滤液腔5，或者所述排气装置和药液过滤膜4与密封腔体2内壁和密闭胶塞3间的密闭空间形成滤液腔5；
所述滤液腔5的至少一个侧壁为输液穿刺位。
此精密过滤输液容器通过密封装置6将容器本体1和密封腔体2分隔开来，在储存状态或者未使用时将药液隔离储存在容器本体1 内，在需要使用时使得药液进入密封腔体2即可，避免药液过滤膜4在使用前长时间浸泡在药液中而导致效能降低甚至失效，且输液穿刺位在滤液腔5内，输液过程中通过药液过滤膜4对药液进行过滤后通过输液穿刺位进行输液，药液过滤膜4上的液体压力低，可减少甚至避免临界滤孔大小的微粒通过，可更好的保障药液的纯净程度，药液过滤膜4上仅存留该瓶药液的微粒，避免不同药物微粒发生非预期反应，减少非热原输液反应，从而对患者提供更高的输液安全保障。作为本发明优选的实施方式，密封腔体2的内腔为中空圆柱形。
作为本发明优选的实施方式，密封装置6为一主体内部凹陷且外部向远端收缩为尖端的可松脱密封块61，所述可松脱密封块61外部的远端顶点与密封腔体2内壁相连，所述可松脱密封块61的内凹部分连接有一拨动启用杆62。
作为本发明优选的实施方式，可松脱密封块61与密封腔体2内壁相连处设有易裂部64，所述拨动启用杆62的外侧设有一操作环63。密封装置6的结构有多种实现形式，在该过滤输液容器投入使用时，可徒手打开密封装置6，使得容器本体1与密封腔体2相通的密封装置6的实现形式均在本发明的保护范围内。
在密封装置6的第一种实现形式中，可松脱密封块61的一端与密封腔体2的内壁相连来分隔容器本体1与密封腔体2内空间，通过拉动拨动启用杆62，可破坏可松脱密封块61的端头与密封腔体2内壁间的连接，即破坏易裂部64，使得容器本体1与密封腔体2的内腔相通，从而药液进入密封腔体2内。
作为本发明优选的实施方式，密封装置6为横置于密封腔体2内的密封板65，密封板65的上下两侧至少有一侧与密封腔体2的内壁进行虚焊密封。
作为实施方式的优选，密封板65的上下侧边分别与密封腔体2内壁间进行虚焊密封。
作为密封装置6的第二种实现形式，两侧面虚焊在密封腔体2内的密封装置6的设置形式，因其加工工艺成熟、分离过程快捷且产生的微粒极少，是本发明中密封装置6的最优选实施方式。
单独一侧面与密封腔体2内壁间虚焊固定的形式不足以保证过滤输液容器运输过程中的安全性，故在密封装置6的两侧侧面均进行虚焊，从而可在更好的保障容器本体1与密封腔体2间隔离性能的同时，更好的保障运输过程中的安全性。
在过滤输液容器使用前，徒手挤压过滤输液容器上密封腔体2的外壁，破坏密封腔体2与密封装置6之间的虚焊连接，即可破坏密封装置6，使得容器本体1与密封腔体2相通。
通过推动杆或者拉动杆来破坏密封装置6的形式，能使得对密封装置6的破坏具有更高的成功率，能保证在紧急情况下，过滤输液容器的快速投入使用。
