Huawei WLAN helps Shanghai Red House Hospital open mobile medical service

Shanghai Red House Hospital is one of the oldest obstetrics and gynaecology hospitals in China. It was founded in 1884. Because of the red roof when it was built, it was affectionately called the “Red House Hospital”. In 2000, the hospital changed its name to the Obstetrics and Gynecology Hospital affiliated to Fudan University. In recent years, it has become the standard setting unit of the Ministry of Health of the Ministry of Health and Obstetrics and Gynecology, and the endoscopic diagnosis and treatment technology training base of the Ministry of Health. It is a nationally renowned medical , teaching and scientific research institute. Third-grade first-class specialist hospital. At present, the Red House Hospital consists of two districts, Huangpu and Yangpu. It covers an area of ​​65 mu and has 820 beds. The annual outpatient volume is more than 1.3 million and the annual inpatients are 46,000.

Mobile healthcare calls for a ubiquitous high-performance network

In order to improve the medical level of hospitals and the medical efficiency of medical staff, Red House Hospital started the medical record system information transformation project, planning and existing HIS (hospital information system), electronic medical record, PACS (image archiving and communication system), LIS (laboratory information) The management system) and other systems complete the docking, thereby realizing the mobile ward round, mobile nursing and mobile medical treatment through the PAD terminal or the cart, so that the medical staff can quickly access the patient's medical record, body temperature list, inspection and inspection, image report and the like in the ward. Requires wireless network coverage to be ubiquitous to ensure that terminals and carts are properly connected to the network.

As a well-known obstetrics and gynaecology hospital in the country, the Red House Hospital has more than 3,500 outpatient visits per day. The outpatient and inspecting services are quite large, while the B-class (ordinary/color/three-dimensional) business generates a large number of medical images for downloading or uploading. The demand requires that the data service capability of the network exceeds 2M, and the image data can be quickly uploaded or downloaded.

Industry-specific requirements for secure and reliable wireless networks

During the hospital visit or treatment, patients are expected to protect their sensitive information such as personal information and illnesses, and require wireless networks to provide data transmission security and network access control.

Medical devices and wireless AP devices generate wireless signals when they work, and may interfere with each other. AP devices can adapt to complex electromagnetic environments and can be automatically tuned according to the electromagnetic environment to ensure that medical devices and wireless networks work properly and avoid medical treatment. Medical malpractice caused by equipment failure or network unavailability. This requires wireless network devices to adapt to complex electromagnetic environments, with redundant mechanisms for critical nodes and links to ensure reliable network availability.

Efficient planning and deployment for fast access anytime, anywhere

The two buildings of Shanghai Red House Hospital have a total construction area of ​​84,600 square meters. The building structure is complex, the flow of people is large and the liquidity is strong. The traditional industrial survey and network regulations cannot be effectively carried out. Based on the rich implementation experience of WLAN networks, Huawei is the first to introduce innovative network-free deployment solutions, eliminating the need for environmental engineering and network planning. With the unique intelligent RF tuning algorithm, AC and AP negotiate to automatically complete channel allocation and power. Optimized, radio frequency blindness and other wireless network rules and network optimization actions, to achieve a seamless network coverage of the inpatient area of ​​the Red House Hospital.

In terms of AP selection, this project selected the high-performance indoor-mounted AP6010DN, which was awarded the German IF Industrial Design Award. The product is designed with a diamond cut surface, which is simple and generous in appearance and perfectly integrated into the surrounding environment. The AP adopts PoE power supply and corridor ceiling installation, and covers 4-6 wards at the same time. The powerful signal through-wall capability ensures the signal coverage quality in the ward; supports dual-frequency dual-space streaming, which provides high-bandwidth access for multiple terminals. Field tests show that when a single AP is concurrently connected to 20 terminals, the average bandwidth of a single user exceeds 4 Mbps, and dozens of medical images can be downloaded or uploaded in a few seconds.

Integrate security policies to ensure peace of mind and peace of mind

Network and data security are the most basic requirements for transport access networks, and the most important indicator for measuring a network solution. Huawei's WLAN solution adopts a converged security policy to deal with various wireless network attacks such as illegal counterfeit APs, secret brute force cracking, and wireless packet interception. It also provides strict control of terminal access and wireless based on security authentication standards such as 802.11i and 802.11w. Messages (data frames and control frames) are encrypted to secure wireless networks and service data.

As one of the drafters of the "Hospital Wireless LAN Construction Regulations (Trial)", Huawei has participated in the standard formulation and has a deep understanding of the medical industry 's convenience for electromagnetic compatibility, electromagnetic safety, RF performance and environmental reliability. The AP6010DN selected for this project has passed. The certification of the authoritative testing organization, Tyre Laboratories, is fully compliant with the requirements of the medical industry and construction regulations to ensure that APs and medical electronic equipment are not interfered with each other. At the same time, the project adopts the VRRP AC 1+1 hot standby solution to prevent AC single point of failure and ensure uninterrupted WLAN network services, supporting the mobile medical service of the hospital.

Mobile medical services improve the medical service level of the Red House Hospital

At present, the medical record system of the Red House Hospital has been completed, and the mobile medical business has been launched immediately. It has laid a foundation for digital diagnosis and treatment and paperless medical records. Medical personnel can quickly access the patient's medical records by carrying a tablet or mobile cart. Medical orders and various inspections, tests, and nursing information have alleviated the work pressure of medical staff, improved the efficiency of diagnosis and ward round, and patient satisfaction is constantly improving.
