Description

一种输液连接器及设有该输液连接器的输液管路和输液器 技术领域
本发明涉及医疗器械领域，特别是涉及一种输液连接器及设有该输液连接器的输液管路和输液器。
背景技术
传统输液器设有外露的输液穿刺针作为输液连接器，穿刺入输液容器内将容器内液体排进输液器，护理人员在更换输液时需手持外露的输液穿刺针操作，容易误伤。
输液穿刺针因表面光滑，附着力低，在插入输液容器时，如因输液器和输液器上附件过多、过重，容易滑脱，形成医疗隐患；同时，因为穿刺针需部份暴露在外界空气中，容易被污染，被污染的穿刺针再穿刺入下一瓶输液时，会导致药液受污染。
现行输液穿刺针基本上设有中空管道以方便药液导流，但设有中空管道的输液穿刺针的生产成本较高，且与其配套的输液容器中的橡胶塞所需穿刺力较大，更重要的是其会带来更多的穿刺碎屑，穿刺碎屑进入输液容器与药液混合对人体形成危害。
护理人员在巡查输液情况时需抬头观察输液容器情况，也需平视观察滴斗情况，增加护理人员工作量。
