How To Choose A Medical Cold Chain Box For Blood Preservation? Blood needs to be transported refrigerated, not frozen, to keep the cells in the blood alive in a low temperature environment. Why does blood need to be refrigerated? How to refrigerate blood for preservation? What kind of blood cooler should I choose? We look at these three aspects.   1. Why should blood be refrigerated? Basically, the modern refrigeration equipment used in blood banks, hospitals or disease control, medical enterprises, etc., are all very advanced, and blood refrigeration will not be polluted much, but many improper operation behaviors in the actual operation process will still occur. cause more or less bacterial contamination. The transfusion of contaminated blood into the user's body can lead to sepsis, a fatal effect.   Blood refrigeration not only requires a strict aseptic working environment and techniques, but also requires a closed and airtight isolation space during refrigeration. Store blood products in a low temperature environment of 4°C ± 2°C according to different requirements.     2. Why should blood be refrigerated? Refrigeration is to maintain the activity of cells. We have seen in many articles about vaccine refrigeration that the activity temperature of cells in vaccines is 2-8°C. The same cell activity in blood also needs to be maintained at the activity temperature. In normal temperature environment, usually blood If it is placed in an environment of >10°C for a long time, it will cause a large number of red blood cells to be destroyed, that is, the red blood cells will die. When the patient is transfused with this improperly stored blood, the symptoms of hemolysis will occur.   Cryopreservation preserves the viability of blood. Cryopreservation can prolong the shelf life of blood. Blood has a low-temperature storage period in the cold storage, which is generally a one-month shelf life. To ensure the life and health of patients.     3. What kind of blood cold chain box should I choose? A blood refrigerator that meets the medical standards and meets the blood transportation requirements of "WS/T 400-2012", the price is not low, so it is very important to choose a blood refrigerator that meets the standards. 1. The cooling methods of the blood refrigerator include active cooling and passive cooling. Active cooling uses a power compressor to actively cool, and the cooling stability of the blood refrigerator and the defense alarm system should be considered. The passively refrigerated blood refrigerator uses a polymer refrigerant ice box to release cooling capacity for cooling. The air tightness of the blood refrigerator, the refrigeration timeliness and the uniformity of the refrigerant ice box release cooling should be considered. At present, there are many refrigerant products on the market. It has passed SGS certification, but the cooling situation is really uneven, and the repeated high and low temperature is more serious. 2. For the use of materials for the blood refrigerator, priority should be given to non-toxic and environmentally friendly materials with qualification certification. The outer shell of the box should be designed to avoid air as much as possible. The harder the surface of the box, the better and firmer.   The heat preservation time of the blood refrigerator has a relatively large relationship with the content of the blood refrigerator. The larger the capacity, the more refrigerant can be placed, and the refrigeration time will be longer. It varies from person to person. box. The usual plastic products passively refrigerated blood refrigerators can maintain a refrigerated environment of 2-8 ℃ at a normal room temperature of 25 ℃, which is very high for 36 hours. If you need to do passive refrigeration and refrigeration for a longer time, you can consider choosing VIP Cold chain box. The material of the insulation layer of the blood refrigerator determines the cooling time. There are many different prices on the market, some of which are low and high. Usually, the insulation layer of the refrigerator with the same capacity and low price is filled with a foam material with a lower thermal resistance coefficient. , This material is very light and easy to foam, but it can only be used for ordinary refrigeration and cannot be used as a better choice for battery life. The thickness of the insulation layer should be selected as much as possible with a thickness of ≥35mm, which can not only withstand high temperature but also low temperature storage.

Today, let's talk about ice packs first! The ice pack is a novel freezing medium. When it is thawed and thawed, there is no water pollution. The ice pack is an upgraded replacement product of ice cubes, this performance is undoubtedly an innovation. With more applicability, it is easy to use, hygienic, and versatile. The following Square Plastic Ice Box Supplier will give you a detailed introduction to the usage of ice packs.   1. The cooling ice pack is a high-tech product, which can be reused and used both hot and cold. 2. It is used for medical cooling and fever, anti-inflammatory and analgesic, cold compress to stop bleeding, physical therapy skin care, cold and hot compress physical therapy bag. 3. Long-distance refrigerated transportation of refrigerated transportation of various biological freezing reagents, medicines, plasma, vaccines, aquatic products, poultry, ornamental fish and fresh-keeping food for trade. 4. Used for sportsmen athletes other than bruises, sprains, falls, etc. during training and competition. 5. Cold compress: physical cooling, fever reduction, anti-inflammatory and analgesic, eliminate fatigue and itching, quickly eliminate the discomfort or pain caused by fever, headache, toothache, sprain, lower back pain, mumps, heat stroke, etc .; also suitable for students to study, exam Cool down to prevent heatstroke and refresh your mind. 6. Warm compress: warm hands, stomach and waist in winter. 7. Refrigerated preservation: used as Lunch Ice Packs, breast milk preservation, beer beverage cold preservation, food, lunch and other items, refrigerated transportation of various biological freezing reagents, long-distance refrigerated transportation of drugs, plasma, vaccines 8. Cakes and moon cake ice packs: There are many ice cream cakes and snowy moon cakes on the market. You can put this ice pack together with cakes and moon cakes so that the cakes and moon cakes will not deteriorate due to the increase in temperature. 9. By heating in a microwave oven and quick freezing in a refrigerator, it can achieve a pure physical health effect that can be applied to the human body both hot and cold. In winter, warm compress warm hands, stomach, waist, and assist in the treatment of arthritis, rheumatoid arthritis, and weak stomach. In summer, cold compresses reduce swelling and wake up the brain, high fever, physical cooling, pain relief, etc., with ice packs and other thermal insulation It can be used for food box lunch preservation, breast milk preservation, iced drinks and so on. 10. Can be stored for a long time, repeated use, comfortable and convenient, is a must-have for modern families, new mothers, hospitals, nursing homes, sports fields and travelers.
