A device for tissue freezing

Abstract

The invention provides a device for tissue freezing technology, belonging to the technical field of fertility preservation, comprising a metal cooler, a freezing carrier and an incubator, the metal cooler is arranged inside the incubator, and the incubator Liquid nitrogen is placed inside, the upper end of the metal cooling device is higher than the liquid level of the liquid nitrogen, the cryogenic carrier is arranged on the top of the metal cooling device, and the metal cooling device includes a handle, a groove and a support body, The handle is installed symmetrically on both sides of the top of the support body, and the curved sides of the handle are all set outwards, and the number of the grooves is multiple, and the grooves are all set on the support body , and the arc surfaces of the grooves are all set below the plane of the top of the support body. The invention is simple and convenient to operate, can avoid cross-infection, effectively solves the loading problem in the tissue freezing process, and is also suitable for freezing ovarian tissue and testicular tissue.

Description

technical field [0001] The invention belongs to the technical field of fertility preservation, in particular to a device for tissue freezing technology. Background technique [0002] Tissue freezing, generally used in medicine and biology, is the cryopreservation of human or animal body tissues. The low temperature environment can stagnate cell metabolism and effectively maintain the integrity of cells. Frozen tissue after thawing and rewarming can be used for research, clinical implantation, etc. The effect of tissue thawing and rewarming depends on the type of tissue, the method of freezing and the control of temperature. [0003] Now with the continuous development of the economy, the environment is being destroyed, and the greatest damage to human beings is the increase of various diseases. Taking human fertility as an example, about 10-15% of the population of childbearing age in my country suffers from it every year. The trouble of infertility, the incidence of ovaria...

Problems solved by technology

[0005] At present, there are two main types of tissue freezing technology: one is a special carrier for commercialized reagents, but this technical solution is expensive, and there are only products suitable for freezing ovarian tissue, but not for testicular tissue. At the same time, operating factors such as liquid nitrogen fumigation have a greater impact on cooling; the other is to prepare a cryoprotectant containing DMSO and use a sperm freezing tube to freeze ovarian and testicular tissue. You can choose to use a programmed cooling device and liquid nitrogen fumigation method, the programmed cooling time of this technical scheme is very long, about two hours. At the same time, although liquid nitrogen fumigation and evaporation cooling is faster, operational factors have a greater impact on it. In addition, the loaded carrier usually uses semen cryopreservation tube replacement
