Description

A precision filter transfusion container

technical field

The utility model relates to the field of medical packaging materials, in particular to a precision filter transfusion container.

Background technique

Among the traditional treatment methods, infusion therapy is one of the important methods. However, there are a large number of insoluble particles in the infusion solution, among which the insoluble particles caused by insufficient drug dissolution occupy the main part.

The traditional infusion container only serves to store the liquid medicine, but cannot filter the insoluble particles in the liquid medicine.

At present, the problem of particles in the infusion is solved by the application of filter infusion sets in clinical practice. Due to the height difference between the filter membrane and the infusion container in ordinary filter infusion sets, the liquid pressure is relatively high, and some particles with a critical filter pore size will also pass through. The filter membrane enters the body. Clinically, there will also be situations where multiple groups of medicines need to be infused for a long time on the same infusion set. In the non-pyrogenic infusion reaction, the excessive number of particles in the liquid medicine is an important factor causing the reaction, and the infusion set used in the infusion process has greatly weakened or lost the filtering effect of the filter due to long-term use, and even became a A source of contamination that increases particulates. At the same time, different drug particles will stay on the filter, increasing the risk of interaction. In addition, the traditional infusion container needs to be punctured with a sharp puncture needle so that the liquid in the container can be discharged into the infusion line. Nurses need to hold the puncture needle when changing the infusion, which is easy to accidentally injure.

When infusion puncture, a certain amount of rubber stopper particles will enter the infusion container, and when the puncture needle is inserted into the infusion container, the infusion set and the accessories on the infusion set are too many and too heavy, so it is easy to slip off, forming a medical hidden danger.
