The invention discloses a portable field blood storage device, which belongs to the technical field of medical equipment. The refrigeration device is used for storing blood transfusion bags, and liquid nitrogen is used as a refrigerant. It will increase the air pressure inside the liquid nitrogen warehouse, and the vaporized liquid nitrogen will be recompressed into liquid by the compressor and flow back into the liquid nitrogen warehouse. This cycle achieves the purpose of cooling the inside of the blood warehouse. The thawing device uses warm water to freeze, and the thawing temperature is not high. At 37 degrees Celsius, the frozen blood bag is placed inside the thawing chamber. The warm water flows out of the water outlet through the frozen blood bag, and the blood bag is thawed by heat transfer. The low-temperature water enters the infrared heating device from the water inlet, and passes through the pump. The cycle is designed so that the cold water heats up as quickly as possible and thaws faster.
