Help the construction of smart hospitals
The three parties of patients, medical staff and hospital management are the service targets of the construction of the “smart hospital” in the first hospital affiliated to the University of Science and Technology of China. Based on the construction of ward management information, the hospital focuses on the entire process of inpatient diagnosis and treatment, starting from different needs such as medical care, patients, equipment, etc., relying on Ocamar’s Internet of Things, cloud computing and other new-generation new technologies to achieve ward medical treatment and management Intelligence.
Currently, the domestic medical IoT applications are dominated by private RFID protocols, but the same protocols are not interoperable. This is also the main problem in the construction of hospital Internet of Things. A hospital using IoT products from different manufacturers at the same time needs to independently build a network, and IoT APs, gateways, RFID readers and other equipment also need to be installed in large numbers. Multi-service deployment has resulted in multiple IoT networks, multiple power supply systems, and multiple management platforms breaking apart. The problem of repeated construction is serious, and management costs and management difficulties will rise linearly.
At the beginning of the construction of the Internet of Things, the First Affiliated Hospital of the University of Science and Technology of China had comprehensively considered the security, stability, scalability and maintainability of the platform. In response to this problem, Ocamar dispelled the doubts of the hospital through a self-developed wireless Internet of Things platform for unlimited medical professionals.
The IoT platform independently developed by Ocamar mainly relies on the IoT basic network platform, the IoT data engine, the IoT data integration platform and the IoT integrated operation and maintenance platform.
Its basic network platform is equipped with a set of 400-6000MHz ultra-wideband antenna system, adapting to various IoT protocols, integrating 5 kinds of wireless networks such as 5G, IoT sensor network, IoT positioning network, Zigbee, WiFi and medical telemetry network. Various IoT information of different standards and different frequency points are covered. The integrated platform can adapt to different types of interfaces and is compatible with most mainstream third-party manufacturer systems in China.
In view of the incommunicable data in the hospital, the Ocamar wireless IoT data platform provides unified data base dictionary management, IoT data distribution modules such as infusion monitoring, body temperature monitoring, and environmental monitoring to implement data cleaning, data standardization, and structuring for IoT services , Interconnect with hospital business systems such as hospital HIS, LIS, and accept external data queries or push data to the outside in real time as needed.
In addition, Ocamar also uses the wireless IoT operation and maintenance platform to monitor the implementation status of multiple IoT application systems and hardware devices in real time from the three dimensions of service objects, service departments, and system equipment, and to operate the sensor tags of the medical IoT. Centralized monitoring of the situation to provide a visual operation and maintenance solution for the hospital.
Five smart medical services
Infusion monitoring, vital signs monitoring monitoring screen
In terms of application scenarios, the First Affiliated Hospital of the Chinese University of Science and Technology has established five smart medical services: smart security services based on safe medical care; smart logistics services based on wireless cold chain and environmental monitoring; and vital signs monitoring system and wireless temperature monitoring Mainly smart nursing services; smart patient services consisting of patient positioning, patient loss prevention, wireless infusion monitoring, in-hospital navigation, and perioperative management in the chest pain center, and smart management services consisting of baby theft, asset positioning management, and medical waste management .
The wireless infusion monitoring system can accurately monitor the infusion speed, margin and end alarm in real time without interfering with the infusion process, and automatically calibrate the zero deviation problem, solve the problem of bottle shake and drip interruption, and help nurses to achieve medical advice Delivery, dosing to the implementation of closed-loop infusion management of the entire process; wireless vital signs monitoring mattresses laid under the bed or sensors worn on the patient, which can supervise the patient’s pressure ulcers, body movements, and off-bed data. Limit or abnormal state alarm, dynamic and continuous collection of vital signs data such as heart rate, breathing rate, body temperature, etc.
The chest pain center uses the Internet of Things technology to achieve an integrated pre-hospital, intra-hospital and post-hospital acute chest pain treatment system, which minimizes emergency response time and provides full course management from diagnosis and rapid treatment to follow-up.
In view of the extremely high low temperature requirements of special medicines, blood and test specimens in the hospital, the hospital uses the Ocamar wireless cold chain management system to place the sensor in the medicine\specimen storage room or refrigerator to monitor the temperature and humidity data in the storage room, which is widely used in hospitals Key monitoring sites such as drug depot, laboratory, biochemical laboratory, blood bank, and contaminated area.
In the field of medical protection, the Internet of Things technology has also been well applied.
In the practice safety of medical personnel, pre-alarms are carried out by wearing badge-type positioning tags for medical personnel. When an emergency occurs, the medical personnel will call the police through the label button with one key, and the police will arrive at the scene as soon as possible; The hospital uses advanced RFID wireless radio frequency technology, relying on a network of Infinite® medical dedicated wireless Internet of Things platform, the signal seamlessly covers the ward, and the sound and light alarm device is arranged at the entrance and exit, which can actively warn, solve the problem of accident lag, and effectively eliminate babies Problems such as theft and miscarriage.
The needs of patients and medical staff for smart hospitals are self-evident, and hospital managers also have demands for smart transformation of hospitals.
The First Affiliated Hospital of the University of Science and Technology of China has adopted an environmental monitoring management system and installed wireless environmental monitors in relevant departments to monitor temperature, humidity, light, noise, PM2.5, PM1.0, PM10, TVoC, CO₂ and other data in real time. The Infinite Medical Professional Internet of Things platform transmits data to wireless environment monitoring software and performs real-time analysis to alarm environmental abnormal events, and at the same time improve air conditioners or ventilation equipment.
Facing a large amount of medical waste, the hospital is based on an unlimited wireless medical dedicated wireless Internet of Things platform. By binding positioning tags for each batch of medical waste, the location information of various types of medical waste is collected in real time, and the information and background data are collected. The collection engine and management software system are interconnected to display and record the basic information and location information of medical waste, so as to track the transportation of medical waste in the hospital, so as to query and supervise various medical waste treatment cycles.
In view of the nearly 1,000 monitors, ventilators, mobile carts and other medical equipment in the hospital that need to be frequently moved and borrowed, the hospital has carried out asset positioning management to facilitate managers to find, inventory and count the time and frequency of equipment use And use trajectory, etc.
5G adds wings to smart hospital construction
In January 2019, the First Affiliated Hospital of China University of Science and Technology and China Telecom Anhui Company jointly built the first “Smart Hospital 5G Joint Laboratory” in China. The two sides combined each other’s advantageous resources to give full play to their resource agglomeration and complementary advantages. They plan to jointly explore the application of 5G technology in convenient medical treatment procedures and optimized management models. Through technological innovation in the medical field, the two parties will further improve the medical experience of the public and improve the rate of medical treatment. Optimize the management model to bring medical services closer to the people.
It is worth mentioning that in the past 5 months, China Telecom first connected the 5G network to Ocamar’s OneNet Unlimited® Medical Specialized Wireless Internet of Things platform in the first aid center of the First Affiliated Hospital of the Chinese University of Science and Technology. Because there is no need to build a new type of digital room subsystem separately, with the support of the passive nature of Ocamar’s unlimited IoT platform, the problem of high construction and operation costs of 5G networks can be avoided, saving a lot of initial construction and later operating costs. In addition, thanks to the seamless coverage properties of Ocamar’s Infinite® Medical Dedicated Wireless Internet of Things platform indoors, all blind spots and dead corners of 5G signals in the hospital are also eliminated.
