Problems solved by technology

In the industrialized production process of freezing and cold storage for medical research, when the temperature of the freezing equipment is lowered, ice crystals are first produced between the cells of medical research, and as the temperature gradually decreases, ice crystals are produced in the cells, which leads to Unbalanced pressure inside and outside the cell, which destroys the protoplasm and cell membrane, leading to cell lysis and death

Abstract

The invention provides a low-temperature quick micro-freezing fresh-keeping technology of medical researches. The low-temperature quick micro-freezing fresh-keeping technology adopts a high-tech biological technology, the ice crystal condition of organism cells under a low-temperature condition is studied, a low temperature and ultra-low temperature technology and a newly-invented micro-freezing fluid from natural components is applied to the medical researches frozen for fresh keeping, an innovative freezing curve is applied, and the medical researches are directly frozen in the micro-freezing fluid for fresh keeping. According to kinds and sizes of materials, freezing fresh keeping of the medical researches is completed in 6-15 minutes or 15-30 minutes, which is presented in the respectsthat cell membranes of the medical researches after the freezing fresh keeping are not frosted to be cracked and are under an organism micro-freezing condition; and then refrigerating is performed soas to maintain the medical researches after the freezing fresh keeping fresh in quality. The low-temperature quick micro-freezing technology is an innovative micro-freezing fresh-keeping technology in the world, the cells of the medical researches are kept not cracked, and the transformation of polysaccharides substances in the medical researches is improved; and when freezing fresh-keeping is performed on the fresh medical researches in the shortest time according to the freezing curve, after the fresh medical researches are stored under the refrigerating condition for 10 years or more, thefresh quality of the fresh medical researches is still maintained.

Description

1. Technical field [0001] The invention relates to the technical field of low-temperature fresh-keeping for medical research, and proposes a low-temperature rapid micro-freeze fresh-keeping technology for medical research. 2. Background technology [0002] We have found that in nature, the somatic cells of hibernating animals have a natural antifreeze mechanism, such as frogs, loach, crucian carp, and other animals and aquatic animals that live in subtropical and frigid regions. The polysaccharide antifreeze substances of somatic cells have a sharp increase in the number of double bonds of fatty acid molecules in their subcellular membranes. The antifreeze is studied from the perspective of cell dynamics, so that the somatic cells are not frozen due to the drop in external temperature. Crystal frost heaves and ruptures; organisms preserve their living bodies by keeping their body cells in a slightly frozen state, and recover and revive when the temperature rises. The evolut...
