Smart medical applications in the Internet of Things
0 Preface The Internet of Things (IOT) is a huge network formed by combining various information sensing devices, such as radio frequency identification (RFID) devices, infrared sensors, global positioning systems, and laser scanners, with the Internet. 12], the purpose is to have all the items connected to the network, so that the system can automatically identify, locate, track, monitor and trigger the corresponding events in real time. Internet of Things technology has the characteristics of wireless transmission, timely sensing, convenient storage and intelligent processing. The key aspects of the Internet of Things include “sensing, transmission and processing†[3]. In terms of network and communication technology, the Internet of Things emphasizes the uniqueness of object addressing, the consistency of communication protocols, and the global nature of the region. The medical field is one of the main application areas of the Internet of Things technology. The Internet of Things technology can realize the exchange and seamless connection of various medical data, real-time dynamic monitoring and continuous tracking management of medical and health care services, and help medical personnel. Accurate medical health decisions, etc., are called smart medical care. 1 Intelligent medical application scope and network framework model 1.1 Intelligent medical application range As an interdisciplinary subject of life sciences and information technology, smart medical care provides users with medical and health interactive services and is an indispensable part of future life. In the field of intelligent medical care, Internet of Things technology can be mainly applied to the supervision and management of medical materials, digitalization of medical information and telemedicine [4]. 1) Supervision of medical materials: to realize the production and logistics tracking of medical equipment and medicines, RFID tags can be used for information and anti-counterfeiting of equipment and pharmaceutical materials. For example, a reader installed in a pharmaceutical production line can automatically identify the information of each drug, transfer it to a database, perform localization and monitoring throughout the circulation, and record relevant information to ensure the quality of the drug. At the same time, it can monitor whether medical waste is legally disposed, realize the whole process of medical waste disposal, and avoid medical safety accidents. 2) Medical information management: Using the Internet of Things technology to realize cloud-based electronic medical records, efficiently and reliably manage electronic health records such as identification and medical history. Protect patients by real-time monitoring of medical equipment and wards. RFID technology will also be applied to blood management to enable non-contact identification and reduce blood contamination. At the same time, the regulation of the baby anti-theft system can be realized [5]. 3) Telemedicine: The health information is transmitted to remote hospitals or doctors through the Internet of Things technology for virtual consultations to achieve ubiquitous and mobile health care. Establishing a remote health service system and providing a comprehensive medical, prevention, and health care platform will help improve and improve the public health service system. 1.2 Intelligent Medical Network Framework Model Smart medical care requires a new generation of life science technology and information technology as a support to achieve comprehensive, thorough, accurate and convenient services. The Internet of Things architecture consists of the sensing layer, the network transport layer and the application layer [6]. The specific architecture diagram is shown in Figure 1. The sensing layer implements intelligent sensing identification, information collection and processing, and connecting physical entities to the network layer and the application layer; the network transport layer mainly implements information transmission, routing, and control; and the application layer includes application infrastructure/middleware and each Internet of Things applications [7]. Figure 1 Intelligent medical application architecture The application layer can be divided into first aid, slow disease, pre-hospital and personal medical services according to different medical business scenarios. First-aid service means that after the patient is sent to the ambulance, the medical staff uses the on-board monitoring equipment to monitor the vital signs of the patient, and sends the collected ECG data and video images to the hospital in real time through the wireless network. The medical experts integrate the vehicle-mounted medical sensors. Collect data and access patient electronic files, timely understand patient status, remotely guide ambulance operations, and save first aid time; chronic disease business refers to the use of personal/family sensors to monitor vital signs when patients are at home or outdoors, and can also monitor vital signs regularly. Through the LAN or WLAN to the medical institution or database, update the information in real time, and the medical staff can track the condition and guide the health care according to the physical information; the pre-patient pre-service refers to monitoring the signs through the hospital-type sensor equipment in the hospital waiting or inpatient environment. Information to provide a reference for doctors to diagnose. Perceptual layer refers to the use of RFID tags, readers, cameras and various medical monitoring sensors to collect physiological data. The purpose is to transform all the people and objects in the network into information physical system (CPS) nodes for easy identification [8]. The sensing layer network supports Ethernet, RS232 and other wired methods and WiFi, ZigBee, RFID, Bluetooth and other wireless methods. The network transmission layer includes a telecommunication network and an internet, and can be divided into an access layer, an aggregation transmission layer, and a core layer, and supports wired access modes such as FTTx, xDSL, and xPON, and wireless access modes such as 2G, GPRS, 3G, LTE, and WLAN. The gateway completes the conversion of the data format and the communication protocol between the sensing layer and the network layer, and realizes interconnection and interconnection of different networks.
