1. Application requirements
The modernization and intelligent construction of temperature and humidity for medical storage and transportation (including cold chain) is the need to realize resource sharing and promote the coordinated development of the national economy. After the completion of the information system, information islands are eliminated, data redundancy is reduced, and the reliability and scientificity of information are improved. The fast and convenient information transmission provides a guarantee for the correct decision-making of higher-level departments, and at the same time improves the level of modern pharmaceutical management and the efficiency of pharmaceutical supervision. At the same time, it also laid the foundation for the construction of medical information management.
1. The monitoring status of domestic medical environment temperature and humidity
At present, most pharmaceutical companies in the domestic medical storage and transportation business mainly conduct independent temperature record management through isolated temperature detection recorders placed in cold storage or refrigerated trucks. This is a blind spot in the management of pharmaceutical companies. Because the management department or the user cannot detect the process status of the warehouse and transportation vehicles in real time. Information including temperature and humidity changes, cooling conditions, driving routes, time of unloading point, temperature and humidity cannot be collected in time. It is also unable to effectively monitor and respond to temporary changes and adjustments.
2. Application of temperature and humidity monitoring system for medical storage environment
A pharmaceutical group’s medical storage and transportation environment temperature and humidity monitoring system adopts RFID electronic temperature and humidity sensor tags to monitor and manage the temperature and humidity of the room temperature, shade, and cold storage of medical storage. Network with customers’ existing business systems and supply chain distribution systems to realize dynamic sharing of data, and provide a unified network platform and application service platform for all parties to provide dynamic information query management.
3. Principles of construction of temperature and humidity monitoring system for medical storage environment
Stability and reliability: The necessary preventive measures for the entire system, through the use of backup, disaster tolerance, fault tolerance and other solutions, provide good stability, ensure the uninterrupted operation and service of the system, and ensure the stability and reliability of the system.
Security and confidentiality: High security of the system and information must be guaranteed. Take necessary precautions to ensure the software and hardware safety of the host and network system; ensure the safety of system applications; ensure the safety of system data.
Ease of use: Use the most commonly used information tools to reduce the workload of training as much as possible.
Advancement: The system adopts internationally advanced, mature and practical technology, which not only guarantees the functions realized by the system, but also ensures that the technology of the system can still meet the needs of application development in the next five years.
Practicability: Design the system in combination with specific applications and actual conditions to meet various functional requirements to the utmost extent.
Real-time: The constructed system is a real-time and reliable platform, which guarantees the real-time of data transmission.
4. The application of temperature and humidity monitoring system for medical storage environment has achieved results
The medical storage environment temperature and humidity monitoring system can help pharmaceutical companies establish a unified environmental temperature and humidity monitoring application platform, which can realize remote monitoring of the temperature and humidity of the medical storage, dynamically grasp the temperature and humidity changes in the medical storage environment, and increase the company’s own medical management The monitoring efforts have strengthened the management of medical storage and circulation, and improved the scientific management mechanism of medical monitoring.
The following are various types of wireless real-time monitoring systems for temperature and humidity created by Mingfei IoT for the medical cold chain:
Mingfei’s three intelligent components
