The protection device easy dismounting that this embodiment provided can adjust each backplate and 2 sizes of apron according to actual demand moreover to the different production demands of adaptation. At the same time, if the biological liquid is transported, the protection device can be loaded on different frame vehicles for transportation. If the biological liquid needs to be frozen and re-melted, the protection device can be loaded on a partition plate of freeze thawing equipment, and the protection device has a fixed and regular shape and can play a good role in solidification in the freeze thawing process because the protection device is different from a disposable liquid bag.

In addition, when a disposable liquid bag filled with biological liquid is placed in the containing cavity, one end of the catheter 4 can extend into the liquid bag to communicate the biological liquid with the external environment, and a channel is reserved for temperature monitoring. Specifically, a through hole 16 is formed in the annular structure 1, and the conduit 4 is located in the through hole 16 and extends into the accommodating cavity. The temperature probe can extend from the outside into the disposable liquid bag containing the biological liquid in the containing cavity through the catheter 4, so as to monitor the temperature of the biological liquid in the process of heat exchange and cold exchange. In order to provide the protection device with good heat conductivity, in the embodiment, the material of the cover plate 2 is preferably stainless steel, and the material of the ring-shaped structure 1 is preferably plastic.

Optionally, the first fixing structure 31 is a magnetic structure, when the first cover plate 21 is mounted, the first fixing structure 31 can be rotated to a position parallel to the plane of the first cover plate 21, and after the first cover plate 21 is mounted, the first fixing structure 31 can be rotated to a position perpendicular to the plane of the first cover plate 21, so that the first fixing structure 31 can be adsorbed on the ring structure 1. Alternatively, the first fixing structure 31 is provided with a magnet, and the ring structure 1 is provided with a magnet or a magnetic substance capable of adsorbing the magnet at a position corresponding to the magnet. Alternatively, the second fixing structure 32 is similar to the first fixing structure 31 in function and assembly manner, and is not described again here.
