技术领域technical field
本实用新型涉及医疗器械领域，尤其是涉及一种分隔膜肝素帽接头。The utility model relates to the field of medical equipment, in particular to a heparin cap joint with a separation membrane.
背景技术Background technique
传统的肝素帽输液接头在使用时，需要使用封管液正压封管，同时需要夹毕止血夹，才能有效防止输液接头旋出时造成的留置针管腔及穿刺血管腔内的负压(输液接头完全旋入时所占体积约为0.3ml)，有效预防静脉留置针回血或堵管的发生。但是在操作时需要两个辅助步骤，即正压封管和关闭止血夹，操作比较繁琐。临床上护士的依从性较差，漏掉其中任一步骤都可能导致留置针堵管的发生。When the traditional heparin cap infusion connector is in use, it is necessary to use positive pressure sealing fluid to seal the tube, and at the same time, it is necessary to clamp the hemostatic clip, so as to effectively prevent the negative pressure in the lumen of the indwelling needle and the puncture vessel caused by the unscrewing of the infusion connector ( When the infusion connector is fully screwed in, the volume occupied is about 0.3ml), which can effectively prevent the occurrence of blood return or blockage of the intravenous indwelling needle. However, two auxiliary steps are required during operation, that is, sealing the tube with positive pressure and closing the hemostatic clip, and the operation is cumbersome. Clinically, the compliance of nurses is poor, and the omission of any of these steps may lead to the occurrence of indwelling needle blockage.

The maximum distance between the internal and external threads of the part 120 is 15 mm, which can ensure that the sealing sleeve film 130 always covers the interconnected parts of the first connecting part 110 and the second connecting part 120 .
可理解，在其他实施例中，该分隔膜肝素帽接头100也可以不含有该密封套膜130，相应的分隔膜肝素帽接头100可以应用在无菌、超净的医疗环境中。It can be understood that, in other embodiments, the septum heparin cap connector 100 may not contain the sealing sleeve 130 , and the corresponding septum heparin cap connector 100 can be applied in a sterile and ultra-clean medical environment.
上述分隔膜肝素帽接头100的第一连接部110内设有第一隔膜112，第二连接部120设有第二隔膜122，且当第一连接部110向第二连接部120套进时，第一隔膜112与第二隔膜122能够配合构成完全封闭该分隔膜肝素帽接头100的输液管道的隔膜，从而在输液结束时，操作者只需常规使用生理盐水或肝素等冲管液后拔出外接针式输液接头，然后将第一连接部110向第二连接部120套进，如套进5mm，使第一隔膜112与第二隔膜122配合完全封闭输液管道，此时，在该分隔膜肝素帽接头100内会自动产生正压，正压的来源为第一连接部110向第二连接部120套进时挤压液体产生的正压(压力的大小为长5mm、直径8.4mm的圆柱体的体积的正压)，此时不必再使用封管液正压封管及使用止血夹，就可以有效消除外接针式输液接头拔出时产生的负压，并在输液管道内形成有效的正压。当需要输液时，操作者只要将第一连接部110向第二连接部120套离，如套离5mm，使第一隔膜112与第二隔膜122分开，输液管道导通，此时，在输液管道内会形成等量的负压(压力的大小为长5mm、直径8.4mm的圆柱体的体积的负压)，负压产生后会自动造成血管内的血液回流(即临床上的“回血”)。“回血”的产生可以明确指示操作者该留置针管仍在血管内，从而操作者不需要再通过回抽血液或预充生理盐水等方法来判断该留置针管是否在血管内，可以有效减少操作者的繁琐监测，有效提高工作效率，减少耗材的浪费。The first connecting part 110 of the above-mentioned septum heparin cap joint 100 is provided with a first diaphragm 112, and the second connecting part 120 is provided with a second diaphragm 122, and when the first connecting part 110 is inserted into the second connecting part 120, The first septum 112 and the second septum 122 can cooperate to form a septum that completely seals the infusion pipeline of the heparin cap joint 100 of the septum membrane, so that at the end of the infusion, the operator only needs to routinely use normal saline or heparin and other flushing solutions to pull out the infusion tube. External needle type infusion connector, then insert the first connecting part 110 into the second connecting part 120, such as inserting 5mm, so that the first diaphragm 112 and the second diaphragm 122 cooperate to completely seal the infusion pipeline. Positive pressure will be automatically generated in the heparin cap joint 100, and the source of the positive pressure is the positive pressure generated by squeezing the liquid when the first connecting part 110 is inserted into the second connecting part 120 (the size of the pressure is a cylinder with a length of 5mm and a diameter of 8.4mm Positive pressure of the volume of the body), at this time, it is no longer necessary to use positive pressure sealing fluid and hemostatic clips, which can effectively eliminate the negative pressure generated when the external needle infusion connector is pulled out, and form an effective pressure in the infusion pipeline. Positive pressure. When infusion is required, the operator only needs to sleeve the first connecting part 110 away from the second connecting part 120, such as 5 mm, so that the first diaphragm 112 is separated from the second diaphragm 122, and the infusion pipeline is connected. The same amount of negative pressure will be formed in the pipeline (the pressure is the negative pressure of the volume of a cylinder with a length of 5mm and a diameter of 8.4mm). ). The generation of "blood return" can clearly indicate to the operator that the indwelling needle tube is still in the blood vessel, so that the operator does not need to draw back blood or prefill normal saline to determine whether the indwelling needle tube is in the blood vessel, which can effectively reduce the number of operators. The tedious monitoring can effectively improve work efficiency and reduce the waste of consumables.
该分隔膜肝素帽接头100结构简单，操作简便，可以有效防止留置针堵管现象的发生。The septum heparin cap joint 100 has a simple structure and is easy to operate, and can effectively prevent the occurrence of tube blocking by indwelling needles.
