Medical IoT also includes a complex and growing infrastructure of connected devices, applications, systems, and services—in this case, embedded in the healthcare industry.
1. Intelligent medical monitoring
Intelligent medical monitoring refers to the real-time monitoring of the health status of the monitored person by collecting various physiological indicators such as body temperature, blood pressure, and pulse through sensing equipment.
1. Mobile vital signs monitoring
Implant mobile and miniaturized electronic diagnostic instruments, such as electronic blood pressure meters, electronic blood glucose meters, etc. into the body of the monitored person or wear it on the monitored person, continuously record various physiological indicators, and communicate through the embedded device. The module wirelessly transmits information to medical staff or family members in a timely manner. Mobile vital signs monitoring is not limited by time and place, which not only facilitates the ward, but also makes up for the shortage of medical resources and alleviates the problem of unbalanced distribution of medical resources.
2. Real-time positioning of medical equipment and personnel
In the process of medical service, the real-time positioning of medical staff, patients and medical equipment can greatly improve the work process, improve the service quality and management level of the hospital, and facilitate the hospital to treat special patients (such as mental patients, mentally handicapped patients, etc.) The monitoring and management of emergency situations can be carried out in a timely manner.
3. Behavior recognition and fall detection
The behavior recognition system is used to measure the distance of the user walking or running, so as to calculate the energy consumed by the exercise, to provide suggestions for the user’s daily diet, and to maintain energy balance and physical health. The fall detection system is to detect accidental falls for some special groups, especially hypertensive patients, and quickly alarm.
The telemedicine monitoring system supports home community telemedicine monitoring systems, hospital clinical wireless medical monitoring systems, bedside critical care monitoring and mobile patient monitoring. The telemedicine monitoring system consists of monitoring terminal equipment and wireless dedicated sensor nodes to form a micro-monitoring network. Medical sensor nodes are used to measure human physiological indicators such as body temperature, blood pressure, blood sugar, ECG, and EEG. The sensor node sends the collected data to the monitoring terminal equipment through wireless communication, and then the communication device on the monitoring terminal transmits the data to the server terminal equipment. In the telemedicine monitoring center, professional medical staff observe the data and provide Necessary counseling services and medical guidance to enable telemedicine.
3. Intelligent medical service
Mobile nursing can assist and guide nurses to complete medical orders, improve nursing quality, save medical staff time, improve the ability to execute orders, control medical costs, and make hospital nursing more accurate, efficient and convenient. The RFID tag worn by the patient can record the patient’s name, age, gender, drug allergy and other information. During the nursing process, the nurse reads the RFID information worn by the patient through the portable terminal, and queries the patient’s related information from the medical information system server through the wireless network. Information and doctor’s orders, such as patient’s physiological indicators, nursing status, medication status, number of temperature measurements, etc. The nurse can record the specific execution information of the doctor’s order through the portable terminal, including the patient’s vital signs, medication status, treatment status, etc., and transmit the information to the medical information system to update the patient’s nursing information.
1. Smart medication reminder
The intelligent medication reminder reminds and detects whether the patient takes medication on time by recording information such as the taking time and usage of the medication. A team from Asia University has developed an RFID-based smart medicine cabinet to remind patients to take their medicines on time and accurately. After the user retrieves the medicine from the hospital, each medicine box or package is equipped with an exclusive RFID tag, which records the usage, dosage and time of the medicine. When the medicine is put into the smart medicine cabinet, the medicine cabinet will record this information. When the medicine needs to be taken, the medicine cabinet will issue a voice notification, and the name and dosage of the medicine will also be displayed on the screen. The user wears an RFID identification tag on the wrist. If the medicine cabinet finds that the user’s information does not match the information of the medicine taken, it will immediately warn the user that the wrong medicine has been taken. If the user does not take the medicine for more than 30 minutes after the reminder, the system will automatically send a message to notify the medical staff or family members.
2. Electronic medical records
Electronic medical records are used to record texts, symbols, charts, graphics, data, images and other information generated in the medical process, and can realize the storage, management, transmission and reproduction of information. It can also record personal health information, such as immunizations, health checkups, health status, etc.
