The two-way wireless cold chain management system for medical care of the Internet of Things has been successfully applied to hospitals and medical institutions in major cities. The typical application case is Wuxi Traditional Chinese Medicine Hospital. Wuxi Traditional Chinese Medicine Hospital is a three-level A Chinese medicine hospital integrating medicine, teaching, research, prevention, and health care. The two-way wireless cold chain management system of the Internet of Things medical treatment uses active RFID temperature and humidity TAG to instantly grasp temperature and humidity data, and solve the current artificial hands. The inaccuracy of the temperature record and the inability to grasp the current and storage temperature data.
The system is fully considered from the perspective of the Internet of Things, and fully reflects the high technical level of the Internet of Things from the perspectives of the perception layer, data layer, and application layer; the software provides intuitive and user-friendly human-computer interaction across the street, complete help information, and administrators can help themselves quickly Training function. At the same time, the maintenance and management of system parameters are also realized through the human-computer interaction interface.
Perception layer: using high-precision (±0.4℃) two-way cold chain tags for the Internet of Things, wireless radio frequencyRFIDTechnology, place the label in each medicine storage room or medicine refrigerator, collect and monitor the medicine storage environment in the refrigerator in real time, and send the data to the data collection node in real time and actively.
Data layer: Using IoT data collection nodes and powerful local area network architecture, upload real-time data to the server, save and process the server database, and have a complete data backup and recovery mechanism, system operation failure self-checking mechanism, and data transmission without cause Loss or damage by accident; in any case, the predictable output is maintained.
Application layer: It has a powerful real-time display function of Internet of Things data and real-time data feedback function. It can quickly provide users with reference information through various information transmission and related output devices, such as LED/LCD display screens, mobile phone text messages, speakers and other devices; When the environmental temperature of the medicine is too high or too low, the management staff will receive the relevant refrigerator abnormal SMS alarm, and there will also be sound and light alarms on the spot; the system is traceable, and can trace the relevant historical records and historical graphs to detect abnormal temperatures. The humidity monitoring points will be automatically extracted to form graphic reports; the system can trace the drug monitoring before the drug is stored in the warehouse, move the cold chain, and solve the problem of vacancies in drug source monitoring.
The IoT medical two-way wireless cold chain management system has many innovations from a technical level, and it is mainly used in provincial and municipal hospitals, nursing homes, blood bank centers and various medical institutions. This system uses IoT RFID technology and uses IoT technology. The networked two-way cold chain tag actively sends the monitoring data to the IoT data collection node, and sends it to the data server through the IoT data collection node, and displays the monitoring data in the form of a graph to visualize and standardize the supervision of drugs, so that patients can be assured of buying drugs , Medication for peace of mind.
The main application demonstration cases of the two-way wireless cold chain management system for medical care of the Internet of Things: Wuxi Traditional Chinese Medicine Hospital, Wuxi Second People’s Hospital, Wuxi Maternity and Child Health Hospital and other hospitals. This demonstration project won the “2011 China Smart Medical Demonstration Project Award” issued by the Ministry of Industry and Information Technology of China, and has been affirmed and supported by many medical institutions. Main implementation locations: drug monitoring locations such as hospital drug warehouses, laboratory departments, biochemical rooms, blood banks, contaminated areas, etc., to ensure the continuity of drug supervision.
Highlights of this application case:
1. Continuity of temperature and humidity monitoring: real-time data collection, rejecting dead ends of temperature and humidity monitoring;
2. Data report visualization: adopt the form of data report curve graph, which is intuitively reflected;
3. Abnormal temperature and degree traceability: Abnormal temperature and humidity can be traced back to form graphic reports;
4. Real-time alarm for abnormal temperature and humidity: remind the people present through the on-site sound and light alarm;
5. SMS notification: SMS notification of abnormal conditions to management personnel to prevent abnormal temperature and humidity at night;
6. Doorman status detection: It can detect the status of the refrigerator doorman, and alarm the refrigerator if the refrigerator is not turned off within the time limit;
7. Statistics of door opening times: Count the number of times the refrigerator door is opened and closed every day.
