Description
Technical Field

Background
The umbilical cord and placenta are important organs for mass exchange between the fetus and the mother, and are the inter-mother and sub-mother tissue-binding organs grown by the combination of embryonic blastoderm and mother endometrium during human pregnancy. After the fetus is produced, the umbilical cord and the placenta are delivered out, which are usually discarded, and in recent decades, research shows that the umbilical cord and the placenta contain various stem cells and can be used for transplanting intervention of eight-system diseases, so that the umbilical cord and the placenta are very important human biological resources.
After the umbilical cord and the placenta are collected, the umbilical cord placenta is required to be transferred from a hospital to a liquid nitrogen tank or an ultralow temperature refrigerator of a preservation warehouse for preservation; during transfer, a pre-cooling protective agent is firstly added into a freezing box (a sterile collection box), then the freezing box (together with a storage object in the freezing box) is sequentially refrigerated at 4 ℃ for 0.5 hour, at-20 ℃ for 2 hours, at-80 ℃ for 1 day, and finally at-196 ℃ for later use; under the influence of the required preservation temperature and preservation cost (the cost of using one refrigerator to regulate the preservation environment temperature for the umbilical cord and placenta from a single parent is high), the delivered umbilical cord and placenta usually need to be frequently transferred in a plurality of refrigerators with different temperatures within 24 hours, and also need to be loaded into a transfer vehicle to be transported to a preservation warehouse; in the transferring process, the freezing box is easy to leak liquid due to violent shaking and dumping, and the transferred vibration can cause adverse effects and even damage to umbilical cords and placenta to be preserved; in the initial preservation, the frequent opening and closing of the refrigerator (taking out and putting in the objects to be preserved) can cause the unstable temperature of the space where the freezing box is positioned; when the freezing box is transferred in each refrigerator, the refrigerating effect is more affected by severe change of the ambient temperature.
