Therefore, the control of insoluble particles has become a subject of general attention in medical care in the world.
In order to solve the above problems, the drug production process should be strictly controlled to regulate the production and quality of infusion sets and injection sets, but the safest, simple and effective method is to use terminal filtration.
At present, infusion sets with terminal filtering functions are widely used clinically in the process of drip infusion for disease treatment. However, the insoluble particles of 15 μm or more can be filtered, and the particles of 15 μm or less cannot be filtered. In recent years, filters capable of filtering insoluble particles of more than 5 microns appear in the market, but because the problem of product structure easily generates gathered bubbles in the using process, although the top of the filter is provided with an exhaust hole, most of the bubbles cannot be removed, and the bubbles have the risk of entering a transfusion pipeline at any time, the risk of air entering blood circulation is greatly improved, and potential safety hazards are caused. Moreover, the material of the existing medical infusion tube filter is a transparent plastic shell, so that the cost is high, the manufacturing process is complex, mass production cannot be realized, manual assembly is realized during assembly, and the production efficiency and the yield are low.
