Why should blood transported in international cold chain be stored in cold storage and how?

Blood storage transport, rather than cryopreserved transport, maintains the activity of cells in the blood at low temperatures. Why does blood need to be refrigerated? How do you refrigerate the blood to preserve it? What kind of blood cooler should you choose?

First, why should blood be stored in cold storage?

Cold storage is to keep the cells active, and those of us who work in medicine and vaccines know that; The active temperature of the cells in the vaccine is 2-8℃, and the activity of the cells in the blood also needs to be maintained at the active temperature. In the normal temperature environment, usually the blood is placed at > 10℃ for a long time, which will lead to the destruction of a large number of red blood cells, that is, the red blood cells will die. When the patient is injected with the improperly preserved blood, hemolysis symptoms will occur.

Low temperature refrigeration to preserve the vitality of blood, low temperature preservation can extend the shelf life of blood, blood in the cold storage has a low temperature storage period, is generally a month of validity, so as to ensure that it can be safely imported into the patient's body, easier to survive in the patient's body, to ensure the life and health of the patient.

Two, how to keep blood cold storage?

Basically, the modern refrigeration equipment used by blood stations, hospitals, disease control and medical enterprises are very advanced. Blood refrigeration will not be contaminated too much, but many improper operations in the actual operation process will cause more or less bacterial contamination. Contaminated blood transfused into users can cause sepsis, which can be fatal.

Blood refrigeration should not only be strictly aseptic working environment and techniques, but also ensure that the closed isolation space, such as the vacuum test tube used in the hospital for blood drawing, is a kind of closed environment. According to different requirements, the blood products are stored in a low temperature environment of 4℃±2℃.
