Embodiment 1

[0056] A precision infusion filter membrane, which includes a membrane body, the membrane body is made of porous alumina material, the surface of the membrane body has 1 million to 1 billion filter holes per square centimeter, and the filter holes The pore diameter is 100 nanometers to 500 nanometers, and the depth of the filter holes (the thickness of the precision infusion filter membrane) is 2 microns to 100 microns.

[0057] According to the filtration needs, the pore size of the precision infusion filter membrane can be set to 200 nanometers. For fine particles with a diameter greater than 200 nanometers, they will be blocked by the membrane body, and particles with a diameter smaller than 200 nanometers can pass through the membrane body. In addition, for some drugs, it is necessary to modify the surface of the precision infusion filter membrane with positive charges to reduce the charge adsorption of active ingredients of the drug on the filter membrane surface.

Abstract

The invention discloses a precision infusion filter membrane and a preparation method, a precision infusion filter membrane structure and a preparation process, a precision infusion filter and an infusion device. The precision infusion filter membrane comprises a membrane body, and the membrane body is made of a porous alumina material. The surface of the membrane body is provided 1 million to 1 billion filter holes per square centimeter, the diameter of the filter holes is 100 nm to 500 nm, and the depth of the filter holes is 2 to 100 micrometers. The filter membrane has the advantages of good biocompatibility, short filtration path, low filtration pressure difference, low filter membrane swelling and small adsorption of drugs, and the filter membrane surface modification is more convenient. The nano ultrafiltration infusion filtering requirements of different types of special drugs and groups like infants can be met. At the same time, the filtering particle diameter can be improvedto below 200 nm.

Description

technical field [0001] The invention relates to a precision transfusion filter membrane and a preparation method, a precision transfusion filter membrane structure and a preparation process, a precision transfusion 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] At present, intravenous infusion is one of the most common methods of drug delivery. The active ingredients in the drug solution are transported into 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 Threa...
