The use of a disposable infusion set for intravenous infusion is an important means of clinical medical treatment. However, as early as the 1930s, clinical use found that the disposable infusion set would cause many hazards during the infusion process, that is, infusion reactions, and this This hazard is largely caused by insoluble particles. Disposable infusion sets can only filter those particles with a diameter greater than 5 microns. For those particles with smaller diameters, disposable infusion sets are powerless. Therefore, a precision infusion set that can filter such finer particles has emerged. According to regulations issued by the State Food and Drug Administration, an infusion set that can filter particles smaller than 5 microns in diameter can be called a precision infusion set.
The precision infusion device has a wide range of applications, whether it is children, elderly patients, cancer patients, critically ill patients, cardiovascular patients, patients who need infusion for a long time, and so on.
The operation method of the precision infusion set is the same as that of the ordinary infusion set. Medical staff can check the expiration date of the precision infusion set, whether there is any air leakage in the package, and other abnormalities before use. The material requirements of the precision infusion set are very high, and the polyethersulfone membrane (PESM) nuclear porous double-layer membrane filtration membrane is used. The pore size of the precision infusion set is uniform, the hydrophobic membrane is not easy to fall off, and the absorption of drugs is very low.
