Problems solved by technology

The polymer nanofiltration membrane is used for the filtration of drugs, and there are mainly the following deficiencies at present: the drug filtration path is long and complicated, which will increase the adsorption of drugs on the filter membrane; the swelling phenomenon of the polymer filter membrane in the liquid medicine , it is easy to cause changes in the filtration channel, resulting in a change in filtration performance; long filtration path, resulting in a large pressure loss and affecting the filtration flow rate
[0009] Therefore, there is no pure inorganic material membrane technology that can reach 0.2 micron in the precision filter mentioned in the above patent or product.

Abstract

The invention discloses an infusion set filtration membrane and a preparation method, an infusion set filtration membrane structure and a preparation process, a filter and an infusion set. The infusion set filtration membrane comprises a membrane body. The membrane body is made of aluminum oxide and provided with a plurality of through filtration holes. A filtration hole pattern formed by the multiple filtration holes is defined by an imprinting mold through an imprinting transfer method. After anodization, the diameter of each obtained filtration hole is 0.1-1 micrometer, the depth of each filtration hole is 2-100 micrometers, and the distance between the filtration holes is 0.5-10 times the diameter of each filter hole. The infusion set filtration membrane has more accurate particle diameter filtration capacity. Meanwhile, the distance between the holes can be freely regulated, so that the infusion set filtration membrane has good mechanical strength, and it is ensured that the infusion set filtration membrane remains undamaged under the normal filtration pressure. Meanwhile, the infusion set filtration membrane also has the characteristics of short filtration path, high structural strength, good sealing performance, small filtration differential pressure, less swelling, less drug adsorption, etc., and can better meet the nano ultrafiltration requirements of infusion of different types of drugs.

Description

technical field [0001] The invention relates to an infusion set filter membrane and a preparation method, an infusion set filter membrane structure and a preparation process, a filter, and an infusion set, and belongs to the technical field of traditional Chinese medicine liquid filtration and infusion sets in the medical industry. Background technique [0002] Intravenous infusion is one of the most common methods of drug delivery. The active ingredients in the drug solution enter the human blood circulation system to treat the diseased area, which has become a common drug treatment method. However, due to the limitations of the current drug production technology, there are often microparticles of different diameters in the drug solution. The infusion process enters the blood system together with the active drug components, and has different degrees of impact on human health. In severe cases, it may cause Threat to human life. In addition, the process of drug transportatio...
