Wuxi People’s Hospital has established the “Medical Internet of Things” academician workstation based on the opportunity of the rapid development of Wuxi Internet of Things to explore the application and development of medical Internet of Things, and continue to optimize medical safety, quality, and services. At present, the hospital mainly implements 8 IoT application projects, namely: medical waste traceability management system, intravenous infusion monitoring system, vital signs dynamic monitoring system, intelligent bed monitoring system, infant anti-theft system, analgesic pump management system, equipment positioning management System and cold chain management system.
1. Medical waste traceability management system
The medical waste management system is a complex system engineering involving coordination among multiple departments, disciplines, fields, and industries. It relies on clear administrative management and organization, sufficient legislation and necessary economic conditions.Moreover, medical waste management is a continuous process. Every link in the whole process from the generation of medical waste to the final disposal should have corresponding follow-ups.
The tracking management system requires periodic monitoring and evaluation, and requires the participation of personnel who have received strict and standardized training.
The hospital tracks the entire life cycle of medical waste through the medical waste traceability management system. Real-time positioning and monitoring of medical waste bins through information management technologies such as electronic labeling management, electronic ordering, electronic monitoring and online monitoring, realizes a new leap from traditional manual processing to modern intelligent management. Through the use of mobile terminals, the system collects all information in real time, including worker login, waste generation department, date, handover time, handover, waste classification, collection quantity, barcode printing, personnel signature, summary report and other functions), the system automatically reminds Differences in waste transportation, online confirmation of waste transportation, etc.
The application of this model has supervised all necessary links, effectively controlling and supervising the collection, transportation, storage, and disposal of medical wastes, ensuring safety, improving management levels, and standardizing waste collection and transportation.
2. Intelligent infusion monitoring system
Intravenous infusion is the most commonly used and most effective important treatment method in clinical medical work. Now hospitals generally use traditional gravity-driven infusion systems. Nurses and patients need to constantly monitor the fluid and replace it when the fluid level is close to the bottom of the bottle. Otherwise, it will Cause a possible medical accident. Such non-stop surveillance tasks increase the burden on nurses and patients, especially at night, making it more likely to have unexpected accidents when drowsy.
The infusion monitor and intelligent infusion monitoring system developed by the hospital allow nurses to monitor the whole process of infusion in real time, including changes in infusion volume, infusion speed, and time required for infusion, and send out an alarm signal when the infusion ends or infusion failures to remind The nurse intervened in time to change the service mode of medical staff from the passive call service of the original patient or accompanying staff to the active service. The implementation of this system realizes the automation and intelligent management of infusion monitoring, which is of positive significance for improving the hospital’s medical efficiency and quality, reducing the intensity of care, reducing the occurrence of medical accidents, and improving social benefits.
3. Dynamic monitoring system for vital signs
With the increasing number of critically ill patients, infectious patients and fever patients in hospitals, nursing staff need to frequently measure body temperature, pulse and other vital signs. Traditional methods for measuring body temperature and other vital signs and data recording methods have many shortcomings and limitations, such as long time, low efficiency, and time-consuming and laborious measurement work.
Wearable medical devices can collect human physiological data (such as blood sugar, blood pressure, heart rate, blood oxygen content, body temperature, respiratory rate, etc.) through sensors, and wirelessly transmit the data to the central processing unit (such as small handheld wireless devices, etc., A warning signal can be issued when an abnormality occurs), and the central processing unit sends the data to the medical center so that the doctor can conduct a comprehensive, professional, and timely analysis and treatment. It is an interactive, flexible, and scalable real-time medical health monitoring system.
The vital signs dynamic monitoring system used in the hospital uses the current advanced sensing technology to monitor the patient’s vital signs in real time: body temperature, pulse, etc. At present, dynamic monitoring of body temperature and multi-parameter vital signs have been realized.
4. Intelligent bed monitoring
A wireless sensor is embedded in the mattress to dynamically monitor the heart rate, breathing rate and sleep dynamics, and the pressure sensor is used to determine whether the patient is in bed or not. If the patient leaves the bed for more than 15 minutes, an alarm will be issued. The system can monitor patient activity in real time to avoid accidents.
5. Baby anti-theft system
Newborn babies are born in the hospital every day. Because the newborn babies have similar appearance and characteristics, and lack the ability to understand and express, if they are not marked effectively, they will often cause problems such as miscarriage and theft of the baby, which will bring catastrophic problems to the hospital and the baby’s family. as a result of.
In order to effectively avoid the above problems, the hospital has implemented a baby anti-theft system. The system relies on the world’s leading RFID radio frequency identification technology, wearing a smart electronic tag that can emit RFID radio frequency signals on the baby and is harmless to the human body. Based on this, the system monitors and tracks the baby’s location in real time, and can also promptly alert the baby’s attempted theft. The infant anti-theft system replaces outdated human defense methods with technical preventive measures, fully improves the hospital’s management level and management level, prevents infants from being stolen from the hospital, effectively protects the safety of infants, and protects the rights and interests of all parties.
6. Analgesic pump management system
Traditional analgesic pumps cannot provide individualized treatments for various pains. At the same time, problems such as “invisible, out-of-control, bedside alarms causing panic” affect medical safety and patient satisfaction.
In order to solve the shortcomings of traditional analgesic pumps, the hospital implemented an analgesic pump management system. The system collects the information of the running wireless analgesia pumps in the form of radio transmission to the monitoring station (central information processing equipment) for analysis and processing, and helps medical staff to centrally and real-time monitor the wireless analgesia pumps in use. Improve the quality and safety of patients requiring precision infusion therapy. The timeliness and traceability of the wireless analgesia management system to the operation and alarm information of the wireless analgesia pump conforms to the basic principles of quality control, which is conducive to the optimization of the patient-controlled analgesia workflow, and realizes the standardized management of patient-controlled analgesia information. Improve the quality control of patient-controlled analgesia in the anesthesiology department.
7. Equipment positioning management system
The management of medical equipment is an important part of hospital management. Through the Internet of Things technology, RFID tags are installed on each emergency equipment to record the basic information of the equipment and the corresponding records of each maintenance, repair, and inspection. Real-time monitoring of usage status and intelligent management of medical equipment.
The hospital has implemented equipment positioning systems in key departments such as ICUs and operating rooms. Each equipment is equipped with a radio frequency chip, which can store a large amount of equipment information, including corresponding records of each maintenance, repair, and inspection. This can prevent damage to the original equipment file files due to uncertain reasons, as well as the loss of equipment information data caused by loss, and it is easy to understand and maintain the condition of each machine during each inspection and maintenance, and Perform corresponding information storage operations, so as to avoid omissions in equipment inspection and maintenance. At the same time, avoid the problem of unclear human responsibility or equipment responsibility if there is a medical liability accident related to medical equipment.
8. Cold chain management system
In order to monitor the storage environment of medicines, blood, etc., the traditional solution is to manually collect the temperature and humidity of the storage cabinet at regular intervals, and manually record and save historical data. The disadvantage of this approach is that it cannot continuously monitor the temperature and humidity of the storage cabinet. In addition, the manual method is not reliable enough and the cost is high.
The cold chain management system implemented by the hospital collects temperature and humidity data information in real time by placing smart wireless sensor tags in the storage cabinets for medicines, vaccines, and blood preparations that need to be monitored. Wait for the whole process to be monitored and tracked to ensure safety. On the one hand, the historical monitoring data of each medicine storage cabinet is saved for inquiries, and on the other hand, the data is analyzed in real time. If the temperature and humidity data exceeds the allowable range of the medicine storage cabinet, the server will immediately trigger the alarm information and notify the relevant information by SMS manager.
