Embodiment Construction

[0030]The medicinal liquid filtration membrane of the present invention is a silicon dioxide ceramic film, the pore diameter of the silicon dioxide ceramic film is 1.8 μm to 2.8 μm, and the porosity is 70% to 75%. According to the filtration requirements, the pore size of the silica ceramic film can be controlled at about 2.5 μm, and the porosity can be controlled at about 75%. Particles with a particle size larger than 2.5 μm will be blocked by the silica ceramic film, and those with a particle size of less than 2.5 μm Particles can pass through a silica ceramic membrane.

[0031] The preparation method of the liquid medicine filter membrane can be illustrated by the following specific examples.

[0032] Silica film can be prepared by thermal oxidation method, MOCVD method and latex-gel method; latex-gel method is generally formed by hydrolytic polymerization of orthoethyl silicate (TEOS) Silica latex precursor, its process can include the catalytic effect, solvent effect an...

Abstract

The invention discloses a liquid medicine filtering membrane. The liquid medicine filtering membrane is a silicon dioxide ceramic membrane, wherein the pore diameter of the silicon dioxide ceramic membrane is 1.8-2.8 microns, and the porosity of the silicon dioxide ceramic membrane is 70-75 percent. The liquid medicine filtering membrane is low in price, high and stable in filtering rate, stable in flow rate, safe and reliable. The invention also discloses a preparation method of the liquid medicine filtering membrane, a liquid medicine filter using the liquid medicine filtering membrane, and a precise transfusion device using the liquid medicine filter.

Description

technical field [0001] The present invention relates to the technical field of liquid medicine filtration and infusion sets, in particular to a liquid medicine filter membrane and its preparation method. The invention also relates to a liquid medicine filter using the liquid medicine filter membrane and a precision infusion using the liquid medicine filter device. Background technique [0002] Maintaining the water and electricity balance of the human body through intravenous infusion has become an important means of daily treatment. Due to the current technology and materials, it is difficult to crush the drug into fine particles and fully dissolve it in the process and equipment used in pharmaceuticals. Among them, the insoluble particles larger than 5 microns are seriously harmful to human tissues or organs. These insoluble particles larger than 5 microns will reach the peripheral blood vessels of the human body through the microcirculation after entering the venous bloo...
