The main application technology in the medical and health field lies in three aspects: material management visualization technology, medical information digital technology, and medical process digital technology.
(1) Monitoring and management of medical devices and drugs
With the aid of the visualization technology of material management, the production, distribution, anti-counterfeiting, and traceability of medical devices and drugs can be realized, avoiding public medical safety issues, and realizing all-round real-time monitoring of medical devices and drugs from scientific research, production, flow to use. Traditional RFID technology is widely used in asset management and equipment tracking applications. People hope to strengthen the application of this technology in drug tracking and equipment tracking through legislation. According to reports from the World Health Organization, the proportion of counterfeit medicines worldwide has exceeded 10%, with sales exceeding 32 billion yuan. According to relevant data from the Chinese Pharmaceutical Association, we have at least 200,000 deaths each year from the wrong or improper use of drugs, and 11% to 26% of the number of unqualified drug users. And about 10% of cases of medication errors. Therefore, RFID technology plays an important role in tracking and monitoring drugs and equipment, and rectifying and regulating the medical supplies market. According to the report of “Global Healthcare and Medical Application Market”, the revenue of RFID in the healthcare and medical application market in 2011 will grow to US$2.3188 billion, with a compound annual growth rate of 29.9%. Among them, the compound annual growth rate of the pharmaceutical tracking market will be close to 32.8%, and the compound annual growth rate of the medical equipment tracking market will reach 28.9%.
Specifically, the application direction of the Internet of Things technology in the field of material management has the following aspects:
1. Anti-counterfeiting of medical equipment and medicines. The identity of the label attached to the product is unique and difficult to copy. It can play a role in querying information and anti-counterfeiting. It will be a very important measure to investigate and deal with counterfeit and shoddy products. For example, by transmitting drug information to a public database, patients or hospitals can check the contents of the label with the records in the database to easily identify counterfeit drugs.
2. Real-time monitoring throughout the process. RFID tags can be monitored in all directions during the entire process of medicines from scientific research, production, circulation to use. Especially when the product leaves the factory, when the product is automatically packaged by itself, the reader installed on the production line can automatically identify the information of each drug and transmit it to the database. During the circulation process, the intermediate information can be recorded at any time to implement full-line monitoring. Through the monitoring of the environmental conditions of drug transportation and storage, the monitoring of transportation and environmental conditions can be achieved. Ensure the quality of medicines. When there is a problem, it can also implement the full traceability based on the drug name, variety, place of production, batch and production, processing, transportation, storage, sales and other information.
3. Medical spam information management. Through the cooperation of different hospitals and transportation companies, a traceable medical waste tracking system can be established with the help of RFID technology to realize the whole process of tracking the medical waste to the treatment plant and avoid the illegal treatment of medical waste. Currently, Japan has launched research in this area and achieved good results.
(2) Digital hospital
The Internet of Things has broad application prospects in medical information management and other aspects. At present, the needs of hospitals for medical information management are mainly concentrated in the following aspects: identification, sample identification, and medical record identification. Among them, identity recognition mainly includes patient’s identity recognition, doctor’s identity recognition, sample recognition includes drug recognition, medical device recognition, chemical test product recognition, etc., and medical record recognition includes patient status recognition, physical sign recognition, etc.
Specific applications are divided into the following aspects:
1. Patient information management. The patient’s family medical history, past medical history, various examinations, treatment records, drug allergy, and other electronic health files can help doctors formulate treatment plans; doctors and nurses can monitor patient vital signs, treatment and chemotherapy, and other real-time information. Put an end to the use of wrong medicines, wrong injections, etc., and automatically remind nurses to perform medicine distribution and inspections.
2. Medical emergency management. In special situations such as the number of wounded, the inaccessibility of family members, and critically ill patients, the reliable and efficient information storage and inspection methods of RFID technology can be used to quickly realize the identification of patients, determine their names, ages, blood types, emergency contact numbers, etc. Past medical history, family members and other relevant detailed information, and completion of the admission registration procedures, bought precious time for the treatment of emergency patients. At present, the technology has been applied in the Wellfordhall Treatment Center in the United States.
3. Storage of medicines. Apply RFID technology to the storage, use, and inspection process of drugs, simplify manual and paper record processing, prevent shortages and facilitate drug recalls, avoid confusion between similar drug names, dosages and dosage forms, and strengthen drug management. Ensure timely and prepared medicine supply.
4. Blood information management. The application of RFID technology to blood management can effectively avoid the disadvantages of small barcode capacity, realize non-contact identification, reduce blood pollution, realize multi-target identification, and improve data collection efficiency.
5. Mistake prevention of pharmaceutical preparations. By adding an error prevention mechanism in the process of taking medicines and dispensing medicines, it is realized in the links of prescription issuance, dispensing, nursing drug delivery, patient medication, drug effect tracking, drug inventory management, drug supplier purchase, shelf life and preservation environmental conditions. Information management of pharmaceutical preparations, confirming the types of preparations used by patients, recording the flow of patient use, and keeping batch numbers, etc., to avoid medication errors and ensure patient medication safety.
6. Traceability of medical devices and drugs. By accurately recording the identity of items and patients, including basic information about product use, specific product information involved in adverse events, areas where the same quality problem product may occur, patients involved in the problem product, and the location of the unused problem product, etc., Trace back to defective products and related patients, control all unused medical devices and drugs, and provide strong support for accident handling. In 2007, my country first tested and established a traceability system for implantable medical devices and patients directly. The system uses GSI standards to identify medical devices and is widely used in hospitals in Shanghai.
7. Information sharing and interconnection. Through the sharing and interconnection of medical information and records, a developed comprehensive medical network is integrated and formed. On the one hand, authorized doctors can check the patient’s medical records, medical history, treatment measures and insurance details. Patients can also choose or change doctors and hospitals on their own; on the other hand, it supports township and community hospitals to achieve seamless connection with central hospitals in terms of information, and can obtain expert advice, arrange referrals, and receive training in real time.
8. Newborn anti-theft system. Combine the maternal and child identification management, infant anti-theft management, and access authority in the obstetrics and gynecology department of a large general hospital or the maternal and child hospital to prevent outsiders from entering and exiting at will, and adopt a reliable protection for babies to prevent miscarriage.
9. Alarm system. Through real-time monitoring and tracking of hospital medical equipment and patients, it helps patients send emergency distress signals, prevents patients from leaving without permission, prevents valuable devices from being damaged or stolen, and protects temperature-sensitive drugs and laboratory samples.
(3) Telemedicine monitoring
Telemedicine monitoring mainly uses the Internet of Things technology to build a patient-centric remote consultation and continuous monitoring service system based on critically ill patients. The original intention of telemedicine monitoring technology is to reduce the number of patients entering hospitals and clinics. According to a 2005 report by the US Centers for Disease Control (CDC), approximately 50% of Americans suffer from at least one chronic disease, and their treatment costs account for more than 3/4 of the US 2 trillion medical expenditure. In addition to the high cost of high-tech treatment and surgery, doctors’ routine check-ups, laboratory tests, and other monitoring services cost approximately billions of dollars. With the advancement of telemedicine technology, high-precision sensors have been able to achieve effective communication within the patient’s body-area network, and the focus of telemedicine monitoring has gradually shifted from improving lifestyles to providing timely life-saving information. , AC medical solutions a. Current related technologies mainly include: ultra-low power DSP specially designed for biomedical signal analysis, low sampling rate/high resolution ADC, low power consumption/ultra-wideband radio frequency, MEMS energy harvester.
