The General Hospital of Guangzhou Military Region was founded in 1933. After 70 years of development, it has become a modern large-scale comprehensive hospital integrating medical treatment, teaching, scientific research, prevention, health care, and rehabilitation. First-class hospitals, 9 teaching hospitals of higher medical schools, Guangdong Province, Guangzhou City, the first batch of public doctors, medical insurance designated hospitals.
The hospital is located on the bank of the beautiful Liuhua Lake. The hospital has 60 specialties, with an annual outpatient capacity of 1.25 million, a receiving capacity of 50,000, and more than 23,000 large and medium operations. There are 9 national drug clinical trial institutions, 1 national key specialized disease center, and 2 post-doctoral research workstations; established trauma and orthopedics, respiratory medicine, clinical anesthesia center, cardiovascular disease center, laser plastic surgery center, neurosurgery, and Urinary Tract Disease Diagnosis and Treatment Center and Clinical Nursing Training Center; 8 military medical specialty (disease) centers, military clinical pharmacology base, health information technology base, family planning and eugenics center; established Guangzhou Military Region critical illness, tumor molecular biology and urology 3 medical research institutes in surgery and 12 military medical research institutes and specialized centers in cardiovascular medicine, nephrology, urology, gastroenterology, general surgery, neurosurgery, dermatology, traditional Chinese medicine, geriatrics and nursing training centers; It has 3 specialty specialties of Guangdong Province, including Urology, Pharmacy, and Traditional Chinese Medicine. The hospital always adheres to the patient-centered principle, pursues the purpose of “serving the military and civilians, contributing to society”, and wholeheartedly provides first-class services to the majority of patients.
Technical solutions
The medical Internet of Things based on the Internet of Things AP is a brand-new solution for the medical industry. It integrates the convenience, mobility, high-speed and security brought by wireless technology (WLAN) to the medical application level, expands the original human-machine dialogue to the dialogue between people and things, things and things, and connects doctors and nurses. In the work process and management, work efficiency and public image have been greatly improved; this project will first implement basic medical information solutions such as mobile nursing and material management, and the future demand for mobile medical care will be extended from exploration to satisfaction The actual demand application stage of various medical business departments.
As a pioneer in medical informatization, the General Hospital of Guangzhou Military Region took the lead in introducing advanced medical IoT solutions. The plan uses two NETGEAR WNAC9505 intelligent wireless controllers and more than 540 IoT APs—WNDAP380R to establish a hospital-wide medical IoT infrastructure. With the continuous growth of the Internet of Things, NETGEAR’s WNAC9505 can also be expanded simultaneously to meet the management needs of thousands of APs in the future. The dual-system hot backup of the two WNAC9505 ensures that the Internet of Things business of the hospital can run in real time without interruption. The network structure diagram is as follows:
The WNAC9505 wireless controller based on the industry-leading intelligent distributed WLAN switching architecture has powerful and flexible wireless user access and Fit AP management capabilities. The whole machine provides up to 1024 Fit APs and 32K wireless user management capabilities. Support 802.11a/b/g/n wireless protocols, and provide seamless roaming, user secure access, WIDS, automatic policy control based on user roles, wireless channel dynamic control, automatic radio frequency power adjustment, automatic load sharing of wireless users, radio frequency RF and application security/control methods, fast roaming, super QoS, IPv4&IPv6 and other functions are integrated.
The NETGEAR WNAC9505 intelligent wireless controller and NETGEAR FIT AP can be easily deployed in any existing Layer 2 or Layer 3 network; the wireless controller and AP are interconnected through the CAPWAP protocol to achieve “zero configuration” of wireless AP And centralized management.
The Internet of Things AP WNDAP380R can transmit 2.4G and 5G wireless signals at the same time. On the one hand, it enhances the coverage effect, and on the other hand, it also effectively avoids interference from other electronic equipment in the hospital (such as X-ray machines, wireless walkie-talkies, etc.). To stabilize the wireless signal.
WNDAP380R has a built-in RFID reader, which can provide passive/active tags, barcodes, vital signs detection, material management and many other applications.
The 1000M physical connection port of WNDAP380R provides high-throughput data forwarding capability, which is suitable for high-speed transmission of large-scale data such as X-ray films in hospitals. NETGEAR’s Gigabit 802.3af POE switch can provide high-speed data forwarding while supplying power to APs, truly realizing a congestion-free wireless network.
Based on the NETGEAR medical Internet of Things architecture, the General Hospital of Guangzhou Military Region will gradually implement mobile outpatient infusion systems, mobile nursing information systems, ICU equipment management systems, central supply room quality traceability systems, medical waste management systems, vital signs collection and monitoring systems, and mobile in the future. The warehouse material management system finally realizes the mobile positioning and monitoring of people and things throughout the hospital, and establishes a medical and health information system that is unified and efficient, resource integration, interconnection, information sharing, transparency and openness, convenient use, and real-time supervision.
Application advantages of medical IoT
The traditional RFID sensor network solves the problems of information collection and object state perception, but the final data display of medical IoT applications still has to be attributed to the applications on the LAN or WAN. The Internet of Things AP can provide the application of WI-FI wireless network and RFID sensor network at the same time, so it can not only monitor and record the location and status information of medical objects in real time, so as to ensure that the data completely reflects the latest information of the patient, while supporting The information is transmitted through the integrated WLAN function, and the data transmission part of the IoT solution is improved. These solutions help eliminate medical errors, save healthcare professionals’ time, and reduce data entry costs. At the same time, it provides the industry’s latest 802.11n standard wireless access, meeting the maximum access speed of 300M and a higher coverage area. The most fundamental of these advantages is to improve the quality of patients’ medical care and effectively improve the level of medical service and brand effect.
The IoT AP systems currently used in hospitals:
● Mobile nursing system
● Mobile outpatient infusion system
● RFID asset management
