2.Key Technologies of Smart IoT
2.1 Sensor Technology
Sensor technology is a critical component in achieving smart healthcare. By leveraging sensor technology, it is possible to collect patient vital signs data and treatment process data, monitor medical procedures, enhance treatment outcomes, and implement end-to-end management of pharmaceuticals from procurement to delivery to the patient.
2.2 Radio Frequency Identification (RFID) Technology
RFID technology is another form of sensor technology that enables rapid read/write operations and long-term tracking and management. It involves embedding chips in materials and medications and linking the chip signals to product information. Hospitals can then use computers and automatic identification systems to monitor materials and medications throughout the entire process.

3.Technical Architecture
The smart healthcare technical architecture is divided into three layers: the application layer, the network layer, and the terminal and sensing extension layer.
The application layer is divided into seven system modules based on healthcare business scenarios:
- Business management system, including hospital billing and medication management systems;
- Electronic medical record system, including patient information and imaging information;
- Clinical application system, including computerized physician order entry (CPOE) systems, etc.;
- Chronic Disease Management System;
- Regional Medical Information Exchange System;
- Clinical Decision Support System;
- Public Health System.
The Network Layer includes wired and wireless networks. Wired networks support Ethernet, serial communication, and fieldbus protocols, while wireless networks support WiFi, mobile networks, RFID, and Bluetooth. The gateway performs data storage and protocol conversion between the network layer and the perception extension layer, and transmits data through the access network. It also has the capability to control and manage business terminals.
Terminals and the perception extension layer refer to various sensor terminals that provide hardware support for medical and health monitoring services. Depending on the application, these sensor terminals can form corresponding sensor networks, such as electrocardiogram monitoring sensors, respiratory sensors, blood pressure sensors, blood glucose sensors, GPS, and cameras.
4.Examples of Technology Applications
4.1RFID Technology for Infusion Error Prevention
Infusion therapy is a critical component of current medical practices, involving high workloads and complex, routine procedures. Any errors can pose serious risks to patient safety. Therefore, it is essential to leverage IoT technology during medication preparation and distribution to mitigate safety hazards caused by non-standardized operations and address issues such as medical errors.
The intravenous infusion error prevention system includes radio frequency transmitters, radio frequency receivers, patient wristbands, and a control center device. Radio frequency transmitters are attached to patients’ medications, and radio frequency receivers establish wireless connections with the transmitters via unique radio frequency signals.
Each patient is assigned a patient wristband upon admission, which is automatically numbered and records the patient’s information by the control center device, generating a unique RF signal. Throughout the patient’s subsequent treatment, each medication or treatment measure, as well as all patient examination and sample specimens, use the same primary identification number.
When the medication preparation center or department adds medications for the patient, each medication is embedded with an RF transmitter.
When medical staff retrieve medications for patient treatment, within the RF signal reception range, the RF receiver on the patient wristband receives the signal emitted by the RF transmitter on the medication, automatically verifies and identifies the corresponding patient information, determines whether the medication is correct, and prevents incorrect treatment.
If the RF receiver detects that the RF signal matches correctly, it immediately emits an audio prompt to indicate correctness. If the RF receiver detects that the RF signal does not match—i.e., the medication is not intended for that patient—it immediately emits an alarm to indicate an error and notifies the control center device. Healthcare personnel can then take appropriate corrective measures.
RF signal verification technology fundamentally addresses errors in the medication dispensing, storage, and treatment processes, thereby reducing medical accidents, alleviating the pressure on medical staff, and mitigating doctor-patient conflicts. Through highly integrated information management measures and advanced IoT technology, the entire medical process becomes transparent and well-organized, with each step uploaded to the control center and recorded as evidence. By connecting data through the control center and forming a big data repository, comparisons and summaries of patient information and treatment processes can be used to derive relevant insights, which can then be applied to assist future treatments.
4.2Nurse workstations based on IoT technology
Each nurse station has many beds and few nurses. Without centralized monitoring and management of all nurse stations, there are many shortcomings in terms of processing efficiency, safety, and resource optimization.
By leveraging IoT technology, new medical services and management functions can be achieved, including automatic patient and staff identification, personnel定位, electronic patient guidance, automatic collection and monitoring of vital signs, electronic ward rounds, and access control. These functions are comprised of the following five subsystems: Patient Identity Matching System, Patient Safety Management System, Real-Time Patient Location Monitoring System, Patient Vital Signs Data Collection and Monitoring System, and IoT Ward Management System. The Patient Identity Matching System registers patient identity information through the admission registration system upon admission and issues a unique electronic tag wristband. For active IoT tags, the information transmitted by the electronic wristband tag worn by the patient can be detected at any time by the wireless IoT detection network, allowing medical staff to identify patient identity information at different locations through workstation computers.
The Patient Safety Management System leverages the online detection and long-range reading/identification capabilities of IoT electronic tags to trigger an alarm at the monitoring console when a patient’s wristband is removed or detached abnormally. When a patient leaves the care area without authorization, IoT detectors at the area’s entry/exit points verify the patient’s authorized identity and alert the workstation console, preventing unauthorized departure from the monitored area.
Under the coverage of the IoT detection network, the real-time patient location monitoring system enables patients wearing IoT wristbands to be under real-time medical supervision, allowing hospitals to provide better medical care based on patient activity. Based on the location of the nearest IoT detection point and the returned IoT wristband information, patient information in the vicinity can be obtained at any time, and medical staff can provide medical services as needed.
The patient vital signs data collection and monitoring system utilizes the data storage and transmission capabilities of IoT, combined with miniature patient temperature measurement probes and mobile vital signs monitoring devices. Under the coverage of the IoT receiver network, it enables online collection and monitoring management of patient vital signs data, allowing patients to receive monitoring care even in unattended scenarios. It provides healthcare personnel with real-time updates on patients’ vital signs and activity status, enabling timely response to emergency care needs.
The IoT ward management system utilizes wireless network coverage and configures mobile IoT nurse workstations, nursing staff can operate online information management devices anytime and anywhere during their daily mobile work, performing tasks such as patient identity verification, data retrieval, location tracking, and medical work record documentation. This eliminates traditional paper-based registration and verification methods, enabling mobile on-site medical care operations management and improving work quality and efficiency.
