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Infusion connector and infusion line and infusion set provided with the same 技术领域Technical field
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。The present invention relates to the field of medical devices, and in particular to an infusion connector and an infusion line and an infusion set provided with the infusion connector.
背景技术Background technique
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。The traditional infusion set is provided with an exposed infusion puncture needle as an infusion connector, and is inserted into the infusion container to discharge the liquid in the container into the infusion set. The nursing staff needs to hold the exposed infusion needle to operate when replacing the infusion, which is easy to be accidentally injured.
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。The infusion puncture needle has a smooth surface and low adhesion. When inserted into the infusion container, if the infusion set and the infusion set are too much and too heavy, it is easy to slip off and form a medical hazard. At the same time, because the puncture needle needs to be partially exposed to the outside world. In the air, it is easy to be contaminated. When the contaminated puncture needle is punctured into the next bottle of infusion, the liquid will be contaminated.
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。The current infusion puncture needle is basically provided with a hollow pipe to facilitate the drainage of the drug solution, but the production cost of the infusion puncture needle provided with the hollow pipe is relatively high, and the rubber stopper in the infusion container corresponding thereto needs a larger puncture force, and What is important is that it will bring more puncture debris, and the puncture debris will enter the infusion container and mix with the liquid to form a hazard to the human body.
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。Nursing staff should look up the infusion container when inspecting the infusion, and also need to look at the drip bucket to see the situation and increase the workload of the nursing staff.
