Customer Background
Founded in 1999, Wuhan Yaxin Hospital is a leading tertiary cardiovascular hospital in China, ranking first in Hubei Province and top three in China for eight consecutive years. At present, there are 750 beds, including 107 beds in the intensive care unit. The first president was Professor Zhu Xiaodong, an academician of the Chinese Academy of Engineering and a famous expert in cardiac surgery; The second president was Professor Zhu Guoying, a famous cardiac intervention expert. The newly built Zhuankou International Hospital of Wuhan Yaxin, with an investment of 1 billion yuan, is a large-scale comprehensive modern tertiary hospital integrating medical treatment, teaching, scientific research, prevention, health care, first aid and rehabilitation, with a construction area of 240000 m2 and 1400 designed beds.
As the cornerstone and driving force of hospital business, information technology, based on the emerging information of "big cloud and material movement", has attracted much attention in the process of building new hospitals. In the construction of Zhuankou International Hospital, Wuhan Yaxin Hospital adopts the construction idea of integration of Internet of Things and WIFI network construction, adopts Huawei's "U" Internet of Things solution, and uniformly carries the applications of mobile ward rounds, infant anti-theft, personnel positioning, asset management, infusion monitoring and other businesses, which greatly improves medical efficiency and reduces medical errors. Through the unified Internet of Things platform, Wuhan Yaxin Hospital can easily cope with the smooth upgrade of subsequent Internet of Things needs.
Medical IoT architecture
Generally, the medical IoT is divided into five layers:
The first layer is the perception layer, which consists of Internet of Things tags, including identity information and data collected by sensors;
The second layer is the Internet of Things gateway, which is responsible for converting non IP radio frequencies such as RFID, ZigBee, NB IoT, Bluetooth, LoRa, etc. to the IP network;
The third layer is the network layer, which consists of the Internet of Things AP, POE switch, network security equipment and wireless controller, and is responsible for data transmission;
The fourth layer is the Internet of Things middleware, which is responsible for docking the data collected by various sensors and business systems with business systems;
The fifth layer is the business system, which uses business data and location information to carry various Internet of Things applications.
Wuhan Yaxin Fully Connected Medical IoT Application
Medical IoT applications can be divided into two categories according to data type. One is related to location information, such as infant anti-theft, asset management, behavior analysis, etc; The other is pure data type, such as vital sign monitoring, temperature and humidity management, etc. According to the scenarios, it can be divided into pre hospital first aid, personnel asset management, medical safety management and recovery monitoring outside the hospital.
In the process of pre hospital first aid for patients, the treatment time is very precious for saving the patient's life. With the help of IoT sensors, patients' real-time vital sign information such as ECG, pulse, temperature and other examination results can be transmitted back to the hospital in real time through 4G network. On the way to the hospital, doctors can complete the consultation in advance, and directly arrange treatment when patients come to the hospital to gain more treatment time.
The medical equipment inside the hospital, such as PACS carts, ventilators and other equipment, will move between different departments. When using the equipment, it often occurs that the equipment cannot be found or even lost. With the help of IoT tags and IoT positioning technology, you can determine the location, status and other information of the device in real time, and quickly find the device. At the same time, combined with the report system, it can summarize the use of equipment, profitability and other information. Once the infusion needle is missed in the hospital, it will cause serious medical accidents. The infrared sensor and gravity sensor system of the infusion pump can monitor the infusion speed, and automatically close the infusion when the needle is missed or the liquid is finished, so as to prevent the occurrence of medical accidents. Through sensors such as heart rate and body temperature, vital signs can be measured without disturbing patients' rest, and automatically recorded into the medical system, which not only improves service efficiency, but also improves medical experience.
