Method and device for preserving tissues, cells, organs and body fluid of animal body or plant body

Abstract

The invention relates to a method and device for preserving tissues, cells, organs and body fluid of an animal body or a plant body. The method comprises the steps of putting disinfected tissues, cells and organs of the animal body or the plant body into a disinfected preservation device; then, putting the preservation device into a freezing dryer, and carrying out freeze drying on the preservation device; then, vacuumizing the preservation device; carrying out hot melt sealing on a discharge hole of the preservation device while the preservation device is maintained to be in a vacuum state, and removing a melt at the upper end of the discharge hole and a sealing plug in a wire-drawing way to enable the melt to become a sealed whole; then, storing the melt for a long time. The tissues, cells and organs of the animal body or the plant body are treated in a sealing way after being treated by freeze drying, so that the tissues, cells and organs of the animal body or the plant body are isolated from the air of the outside so as to be conveniently stored at the room temperature, the preservation conditions and preservation cost of the tissues, cells and organs of the animal body or the plant body are greatly reduced, and convenience is provided for promotion and application of the technology.

Description

technical field [0001] The invention relates to the field of preservation of animal and plant tissues, organs and body fluids, in particular to a method and device for preserving animal / plant tissues, cells, organs and body fluids. Background technique [0002] The preservation of organic matter in the fields of biology, medicine and food has always been a concern, especially in the fields of clinical medicine and biology, where animal / plant tissues, cells, organs and body fluids often need to be preserved for a long time and maintain biological activity In the process, in order to inhibit the biochemical reaction of bacteria and biological enzymes and prolong the storage time, cryopreservation technology is usually used, but organisms, tissues and organs are easily damaged and lose biological activity during the cooling and rewarming process, which requires very high technology , and the preservation and rewarming process after cooling is also a major technical challenge, e...
