Abstract

An infusion connector. The infusion connector is provided with a body (1) with the outer surface and the outer edge being of a non-sharp structure and a separator (123), so that a nurse is prevented from being exposed in a sharp infusion puncture environment during an infusion operation. By bluntly breaking a rosin joint between sealing membranes by virtue of the separator (123), a liquid outlet of an external infusion container can be opened, and few particles or debris are produced, so that the harm of the particles or debris entering the infusion container to be mixed with liquid medicine on the human body can be reduced. By providing a connection structure in the form of a thread structure, a snap structure, etc., the infusion connector can be fixedly connected to the external infusion container, and more infusion accessory components can be carried, so that a medical worker can select more infusion accessory components suitable for a patient's medical condition. The match with the opening of the external infusion container enables quick infusion to be implemented. By providing a barrier device (15) to keep the separator (123) clean, safer infusion can be provided to the patient. The infusion connector is used in the field of medical devices.

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.
现行输液容器大部份使用密封胶塞对输液容器开口进行密封，在输液穿刺过程中，输液穿刺针穿刺密封胶塞容易产生大量的不溶性微粒落入药液中，如果大量不溶性微粒进入人体，容易引起输液反应、血管炎、血管堵塞等，对人体造成危害。Most of the current infusion containers use a sealing rubber plug to seal the opening of the infusion container. During the infusion puncture, the infusion needle piercing the sealing rubber plug is prone to generate a large amount of insoluble particles falling into the liquid. If a large amount of insoluble particles enter the human body, it is easy. Causes infusion reactions, vasculitis, vascular occlusion, etc., causing harm to the human body.
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。如输液治疗场所中存在有耐药性致病原(如耐药性金葡萄球菌等)，或者在同一输液治疗场所中有高致病性致病原的传染性病人时容易造成院内感染，增加病人治疗费用和延长治疗所需时间，甚至危及病人生命。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. If there is a drug-resistant pathogen (such as drug-resistant Staphylococcus aureus) in the infusion treatment site, or if there is a highly pathogenic infectious agent in the same infusion treatment site, it is easy to cause nosocomial infection, increase The cost of treatment for patients and the time required to prolong treatment can even endanger the lives of patients.
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.
