what circumstances prohibit the use of precision filter infusion

intravenous infusion through disposable infusion device is an indispensable and important method and means in clinical treatment, as early as the 1930 s, clinical use found that disposable infusion devices would have a variety of hazards in the infusion process, namely infusion reactions, and the results of the study proved that a large part of the clinical hazards caused by infusion were caused by insoluble particles.

the filtration membrane of the disposable infusion device can only filter particles with a diameter greater than 5 microns, and particles with a diameter equal to or less than microns, the disposable infusion device cannot be filtered, so the demand for an infusion device capable of filtering particles with a diameter of 5 microns and less arises at the historic moment.

According to the regulations issued by the State Food and Drug Administration, infusion devices that can filter particles with a diameter of 5 microns and smaller are called precision filtration infusion devices.

precision infusion set and the common infusion set used before lies in the filter diameter of the particles in the liquid, which is smaller in precision, which can reduce the side reaction of infusion and reduce the possibility of infusion reaction. For what kind of liquid must be used is not clearly defined. Generally, the liquid that is irritating and prone to infusion reaction is recommended to use precision infusion set. For example, azithromycin, some proprietary Chinese medicine preparations (Salvia miltiorrhiza, Chuanqiangqin, Shenda attached, etc.). But now many hospitals have eliminated ordinary infusion devices, and all drugs use precision infusion devices. In fact, the specific requirements are different from place to place, and even the requirements of different departments in a hospital are different.
