Description

一种精密过滤输液容器Precision filtration infusion container 技术领域Technical field
本发明涉及医用包装材料领域，特别是涉及一种精密过滤输液容器。The invention relates to the field of medical packaging materials, in particular to a precision filtration infusion container.
背景技术Background technique
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。Infusion therapy is one of the important ways in traditional treatments. However, a large amount of insoluble particles are present in the infusion, and insoluble particles due to insufficient dissolution of the drug occupy a major portion.
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。The traditional infusion container only provides the function of holding the liquid medicine, and cannot filter the insoluble particles in the medicine liquid.
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。且传统输液容器需用锐利的穿刺针进行输液穿刺，以供容器内液体排进输液管路，护理人员在更换输液时需手持穿刺针操作，容易误伤。At present, the clinical application of filtration infusion sets to solve the problem of particulates in infusions. The ordinary filtration infusion sets have a certain height difference between the filtration membrane and the infusion container, and the liquid pressure is large, so that some of the critical pore size particles will also pass. The filter membrane enters the body. Clinically, multiple sets of drugs and long-term infusions on the same infusion set will occur. In the non-pyrogen infusion reaction, the excessive number of particles in the liquid is an important factor causing the reaction, and the infusion set used in the infusion process, because of the long-term use, greatly reduces or loses the filtering effect of the filter, and even becomes A source of pollution that increases particulates. At the same time, different drug particles will stay on the filter screen, increasing the risk of mutual reaction. Moreover, the traditional infusion container needs a sharp puncture needle for infusion puncture, so that the liquid in the container is discharged into the infusion line, and the nursing staff needs to hold the puncture needle when replacing the infusion, which is easy to be accidentally injured.
作输液穿刺时会产生一定量的胶塞微粒进入输液容器且穿刺针 ***输液容器时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。When infusion puncture, a certain amount of rubber stopper particles are generated to enter the infusion container and the puncture needle When the infusion container is inserted, the attachments on the infusion set and the infusion set are too much and too heavy, and it is easy to slip off, posing a medical hazard.
