In the field of health care, the main application technologies are three aspects: material management visualization technology, medical information digitization technology, and medical process digitization technology. (1) Monitoring and management of medical devices and drugs With the visualization technology of material management, it is possible to realize the production, distribution, anti-counterfeiting and traceability of medical devices and drugs, avoid public medical safety problems, and realize comprehensive real-time monitoring of medical devices and drugs from scientific research, production, and flow to use. Traditional RFID technology is widely used in asset management and device tracking applications. It is hoped that legislation will strengthen the application of this technology in drug tracking and device tracking. According to the World Health Organization, the proportion of counterfeit drugs in the world has exceeded 10%, and sales have exceeded 32 billion yuan. According to relevant data from the Chinese Pharmaceutical Association, at least 200,000 people die each year from misuse and misuse of drugs, and 11% to 26% of unqualified patients. And about 10% of cases of medication errors. Therefore, RFID technology plays an important role in tracking and monitoring drugs and equipment, and rectifying the market for medical products. According to the "Global Health and Medical Applications Market" report, the revenue of RFID in the Health care and medical applications market will grow to $2,318.8 million in 2011, with a compound annual growth rate of 29.9%. Among them, the compound annual growth rate of the drug tracking market will be close to 32.8%, and the compound annual growth rate of the medical device tracking market will reach 28.9%. Specifically, the application of IoT technology in the field of material management has the following aspects: 1. Medical equipment and medicine anti-counterfeiting. The identity of the tag attached to the product is unique, difficult to copy, can play the role of query information and anti-counterfeiting, and will be a very important investigation and punishment measure for counterfeit and shoddy products. For example, by transmitting drug information to a public database, the patient or hospital can check the contents of the tag and the records in the database to easily identify counterfeit drugs. 2. Full-time real-time monitoring. RFID tags can be monitored in all aspects from the scientific research, production, circulation to use. Especially when leaving the factory, when the product is automatically packaged by itself, the reader installed in the production line can automatically identify the information of each drug and transfer it to the database. During the process of circulation, the intermediate information can be recorded at any time to implement full-line monitoring. Transportation and environmental conditions monitoring can be achieved through monitoring of drug delivery and storage environmental conditions. Ensure the quality of the drug. When problems arise, it is also possible to carry out full traceability based on the drug name, variety, origin, batch and production, processing, transportation, storage, sales and other information. 3. Medical waste information management. Through the cooperation of different hospitals and transportation companies, RFID technology can be used to establish a traceable medical waste tracking system to track the whole process of medical waste transportation to the treatment plant and avoid illegal disposal of medical waste. At present, Japan has carried out research in this area and achieved good results. (2) Digital hospital The Internet of Things has broad application prospects in medical information management. At present, the hospital's demand for medical information management mainly focuses on the following aspects: identification, sample identification, and medical record identification. Among them, the identification mainly includes the identification of the patient, the identification of the doctor, the identification of the sample includes drug identification, medical device identification, identification of the test article, etc., and the identification of the medical record includes the identification of the condition and the identification of the vital signs. The specific application is divided into the following aspects: 1. Patient information management. The patient's family history, past medical history, various examinations, treatment records, drug allergies and other electronic health records can help doctors to develop treatment plans; doctors and nurses can do real-time monitoring information on patient vital signs, treatment chemotherapy, etc. Eliminate the use of wrong drugs, misplaced needles, etc., automatically remind nurses to carry out drugs, inspections and other work. 2. Medical emergency management. In the special case of more casualties, inability to obtain family contact, critical illness, etc., with the reliable and efficient information storage and testing methods of RFID technology, the patient identification can be quickly confirmed, and the name, age, blood type, emergency contact number, Detailed information on past medical history, family members, etc., completed the admission procedure, and won valuable treatment for emergency patients. The technology is currently used in the Wellfordhall Treatment Center in the United States. Xi'an JCF Herb Technology Development Co., Ltd , https://www.jcfherb.com
