With the high level of development of modern medicine, human life expectancy continues to increase, but diseases are never absent, while accidents are frequent, leading to a rising demand for blood in society. The main component of blood is protein, which will denature and necrosis at room temperature, especially the various cells inside the blood are active. Its storage is welcome to vary depending on the composition, but basically it needs to be stored in a cold chain environment. Humpback whale hospital blood storage temperature and humidity monitoring solutions are designed to monitor the temperature of refrigerators and freezers in blood banks, hematology departments and laboratory departments of hospitals, CDCs and community hospitals to ensure the storage safety of blood and test samples. It is extremely important to strengthen the integrity of the blood cold chain and ensure the quality of blood. While ensuring the quality of blood, it is also related to the efficacy of clinical transfusion, reducing the occurrence of transfusion reactions and ensuring safe clinical transfusion.

Challenge

At present, most of the domestic hospital hematology department and laboratory is tending to use calibration thermometer to monitor the temperature of blood refrigerator and sampling refrigerator, individual refrigerator can not form a network between, there is a certain management vacuum, and according to the requirements of the protocol, need manual operation, in the morning and afternoon to do temperature records, time-consuming and laborious, and there is a certain possibility of deviation, the lack of traceability, such as emergencies Can not be found in time, more can not be the first time on-site solution, easy to cause blood loss of temperature, the formation of unnecessary losses, and manual opening and closing the refrigerator door record data and refrigerator storage blood requirements of the relative constant temperature to produce a certain contradiction and conflict, difficult to overcome. In addition, due to refrigerator failure or other reasons accidental power failure, resulting in loss of temperature, resulting in blood quality accidents is also difficult to avoid.

Solution

The LoRa solution automatically measures and controls the temperature in the refrigerator through the temperature probe, and through LoRa technology, it realizes the transmission of 24-hour uninterrupted detection, alarm, record and data storage and query of the temperature of the refrigerator; according to the set temperature threshold, the on-site alarm sounds, remote alarm, SMS and WeChat directed alarm, etc. The gateway in the LoRa solution covers a wide range of areas, and the gateway has a display screen, so that the real-time temperature of the temperature probe under the jurisdiction of the hospital's blood department, laboratory department or CDC management can also query the history and status of the responsible area through the network or mobile phone. Display screen, for the jurisdiction of the temperature probe real-time temperature at a glance, the hospital blood department, laboratory department or the CDC management personnel can also be responsible for the region through the network or cell phone query temperature history and the actual situation; finally achieve centralized control of the refrigerator, to achieve real-time online supervision of the refrigerator temperature, the blood refrigerator and sampling refrigerator problems generated by reducing the impact to a minimum, the risk of elimination in the The main equipment used in this solution includes The main equipment used in this program includes LoRa gateway with screen, built-in temperature and humidity probe, external temperature and humidity probe, ultra-low temperature probe, etc.
