Cryopreserving color box set clamping base special for IVF laboratory

Abstract

The invention discloses a cryopreserving color box set clamping base special for an IVF laboratory. The clamping base comprises a transparent bottom box and a transparent top cover, wherein, a middle sleeve is arranged in the transparent bottom box, the outer wall of the middle sleeve is sleeved with a freezing storage bin and a clamping base disc, and a plurality of fan-shaped grid bins arranged around the middle sleeve in an array mode are arranged in the freezing storage bin; fan-shaped areas which are the same as the fan-shaped grid bins in number and correspond to the fan-shaped grid bins in position are arranged in the clamping base disc, installation bayonets which are sequentially arranged at intervals from inside to outside and are enlarged in area are arranged in each fan-shaped area, and positioning protruding points are arranged on the inner wall of the periphery of each installation bayonet. According to the clamping base, cryopreserving tubes are stored in the fan-shaped grid bins in order at intervals through the clamping base discs, so that the loading number of the cryopreserving tubes is increased, the storing and taking efficiency is improved, meanwhile, relatively independent surrounding space gaps are kept between the cryopreserving tubes located below the liquid nitrogen level and are filled with liquid nitrogen, and the temperature of the inner space of the cryopreserving tubes is uniform without temperature difference level during cryopreservation period, so that the cryopreservation quality is improved.

Description

technical field [0001] The invention relates to the technical field of embryo storage devices, in particular to a special cryopreservation color box suit holder for IVF laboratories. Background technique [0002] Human in vitro fertilization and embryo transfer technology widely uses the method of slow freezing and rapid thawing for cryopreservation of human eggs and embryos, but this method is time-consuming, requires expensive programmed freezers, and has a poor freezing effect on eggs. The vitrification method developed in recent years has an ultra-fast freezing rate due to the use of a higher concentration of cryoprotectant, making freezing simpler, faster and more efficient. [0003] At present, domestic freezer resources are very scarce, and IVF freezer resources are even more precious. The freezing method adopted by the existing IVF laboratory is to put the vitrified cryopreservation tubes loaded with biological samples into the "frozen colorful box" with the transpa...

AI Technical Summary

Problems solved by technology

Each fan-shaped compartment can store 19 cryopreservation tubes (3.0mmX3.0mm specification), with a total capacity of 190 tubes. The cryopreservation tubes are not in sequence, numbered, arranged in disorder, and they are loose or close to each other. Together, it may be skewed, resulting in time-consuming storage for medical workers, and the number of cryovials loaded in a single color grid is small
