Abstract
The process of preparing solution for improving oxygen supply of organism tissue belongs to the field of biomedicine technology. The mother liquid is emulsified perfluoro carbon compound in the granularity of 0.1-0.3 microns. The mother liquid is prepared with the materials including perfluoro triethylamine, perfluoro tripropylamine, perfluoro tributylamine, perfluoro decalin, perfluoro adamantane, phospholipid, distilled water, etc, and through compounding, mixing, emulsifying, filtering and packing. The mother liquid is added with dextran, sodium salt, potassium salt, liver growth factor and other supplementary material based on different uses to prepare different types of oxygen supply solution for oral taking, venoclysis, gastrointestinal perfusing or external use. The oxygen supply solution may be used in treating various diseases caused by anoxia.
Description
technical field [0001] The invention belongs to the technical field of biomedicine, and in particular relates to a method for preparing an emulsion for improving oxygen supply to body tissues. Background technique [0002] The prior art and product similar to the present invention are the temporary blood substitute Fluosol for injection produced by the Japanese Green Cross Company nearly 20 years ago. . Fluosol It is composed of 14% w / v perfluorodecalin and 6% w / v perfluorotripropylamine, emulsified by synthetic poloxamer, Pluronic F-68. The main disadvantage of its technical products is that the preparation process is complex, requiring ten processes such as mixing, stirring, and static reaction. One production cycle takes 5 working days, and the output is small, so the price is expensive. The product needs to be thawed and mixed before use, and the ingredients of the mixed product are unstable, with a stability period of only 8 hours, can only be used for intravenou...
