Features of medical blood refrigerator
In order to effectively preserve whole blood, improve the treatment effect of hemorrhagic patients. The whole blood used for blood transfusion therapy must be stored in a medical blood refrigerator at 4°C in order to preserve the vitality of the whole blood to the maximum extent.
So why is a medical blood refrigerator the most suitable device for storing whole blood? This is because of several major characteristics of the medical blood refrigerator.
1. The best storage temperature for whole blood is 4℃. The main components of whole blood are red blood cells and plasma, and various whole blood preservation solutions are mainly designed for red blood cells. When the red blood cells are in the body, they continue to increase nutrients and metabolize waste products. The temperature of 36-37°C makes it full of vitality, and its metabolism is vigorous, transporting necessary nutrients and fresh oxygen to the body. Once out of the body, everything changed. Nutrients. It's not as rich as it is in the body, and it doesn't need to send all kinds of nutrients to it. All that is needed is to save the strength and wait for it to enter the body again to play a role. Therefore, at this time, the metabolic activity of red blood cells should be reduced, various consumptions should be slowed down, and life span should be prolonged, and 4°C is the best temperature. If it exceeds this temperature, the consumption of red blood cells will increase, accelerating aging and producing hemolysis prematurely. The rate of aging is proportional to the temperature. The validity period set for various whole blood and red blood cell preservation solutions refers to the time that they can be stored at a temperature of 4℃. Once the temperature changes, the preservation time will naturally change, that is, the validity period is shortened. This is why some contain An important reason for hemolysis of red blood cells before the expiry date. Therefore, once whole blood is collected, it should be stored at 4°C immediately. The design temperature range of the medical blood refrigerator is 4±1℃. Since the actual temperature of the refrigerator must fluctuate periodically, 4±1℃ is the best storage temperature range.
2. Since the refrigerator is a volume with a certain space and the blood consumption in large hospitals is very large, a large number of whole blood bags are often placed in the refrigerator. Then it must be ensured that the temperature of any space in the refrigerator must be within 4±1°C to ensure the best preservation of the blood bag. Conventional household refrigerators or non-professional medical refrigerators often do not have this characteristic. Therefore, it is very easy to have local blood bag preservation problems, and doctors can't distinguish it, and it is very easy to cause medical accidents in the end. Professional medical blood refrigerators attach great importance to this point, and have designed various circulating air to ensure that the temperature of any space in the refrigerator is within 4±1°C.
3. The medical blood refrigerator also has many characteristics in appearance and structure. Generally, the inner box is made of anti-corrosion stainless steel, and the outer box is made of soft and beautiful anti-corrosion sprayed steel plate. With this appearance design, the inner box material has antibacterial and anti-corrosion properties, and the outer box appearance is more suitable for use in such places as hospitals and blood stations.
Fourth, in order to be suitable for doctors and nurses to operate and use, medical blood refrigerators are often equipped with special blood bag baskets for easy use. And can ensure that the refrigerator space utilization rate is maximized.
5. Because the blood bags stored in medical blood refrigerators are very important, professional medical blood refrigerators have various alarm prompt functions. It has five failure alarm functions: high and low temperature alarm, power failure alarm, door open alarm, sensor failure alarm, backup battery failure alarm, and three alarm methods: sound buzzer, light flashing, and remote alarm. Various problems can be timely It effectively reminds the doctor to prevent the problematic blood from being used on the patient.
The professional medical blood refrigerator also has many features that other refrigerators do not have. In order to ensure that there is no problem with the stored blood, a unique design is carried out on the refrigeration system and the computer control system. Therefore, a professional medical blood refrigerator is the most suitable equipment for blood preservation.
