'From blood vessel to blood vessel' blood cold chain monitoring system guarantees blood safety
In the spring of 2020, the new crown epidemic swept across the country, and my country's blood products played an important role in the prevention and control of the epidemic, and performed brilliantly. As a 'blood famine' country, due to backward technology, there are still many uncontrollable factors in the traceability of food, medicine and blood safety in my country in recent years.

The production of blood products in my country began in the 1960s and has a history of nearly 70 years. According to major events in my country’s blood products industry, my country’s blood products industry has gone through the stage of independent exploration from the early technological blockade to the extensive development and gradual regulation after reform and opening up. As the regulatory measures continue to be strict, the industry has entered stock competition and strict The stage of supervision. The society is paying more and more attention to the safety of blood transfusion, which also means higher requirements for blood cold chain management, which is closely related to blood quality. Therefore, blood management calls for safer, more effective and smarter technical means. Avoid 'waste' of blood!

The blood cold chain monitoring system is a set of systems for the storage and transportation of blood and various blood products. Its main purpose is to ensure the quality of blood from the donor’s blood vessel to the blood vessel of the transfusion, and reduce the blood rejection rate. The blood cold chain monitoring system monitors the whole process of 'from blood vessel to blood vessel' from blood collection to infusion, scientifically and effectively manages the key links of blood, and improves blood utilization.

For the blood cold chain monitoring system, the core is temperature control. Blood and blood products are different from general medicines and are special medicines to save the lives of patients. When blood is in an external environment, in order to preserve biological activity, its various components require different storage temperatures. Transport of whole blood and red blood cell components (excluding frozen red blood cells) should be maintained at 2-10°C; transport of frozen blood and cryoprecipitate should be maintained in a frozen state; transport of platelets should be maintained at 20-24°C as far as possible; Frozen red blood cells should be maintained at -5°C or below.

In actual work, it mainly monitors the temperature of blood storage equipment and transportation tools (equipment includes all the equipment needed for safe storage and transportation during the whole process from the beginning of collection to the end of blood transfusion), and the temperature monitoring of traditional blood storage equipment Personnel observation is required, manual recording is laborious and cumbersome, the recorder is relatively random, lacks effective supervision, and poses a safety hazard to the quality of blood. Real-time monitoring of the temperature of all blood storage refrigerators is implemented through the network. The temperature data and alarms of all blood storage refrigerators are regularly sent to the on-duty monitoring room through a dedicated network. The temperature over-limit alarms can be processed in time, which effectively guarantees the safety of blood in the cold storage process; strengthened Cold chain control during blood transportation is one of the important factors to ensure blood quality. Through personnel and transportation process management (including blood packaging and temperature control during transportation), it is necessary to formulate corresponding procedures for the measures taken by blood products outside the regulations to control the transportation conditions. Regular control, supervision and inspection of blood quality are carried out to ensure the quality of blood transportation.

The cold chain of blood storage and transportation is a link with poor stability. It is very important to strengthen cold chain management to ensure blood quality. The establishment of a blood cold chain monitoring system through information technology is of great significance to the supervision of blood transportation.
