Application of electronic tags in the field of disease control and medical treatment

During the period when SARS was raging in China, many people were quarantined because of suspicion. After some SARS-infected persons walked out of the quarantine area without authorization, what medical staff most want to know is who these people have been in contact with, and where these people have been. Therefore, some countries wear a special electronic radio frequency tag on the medical staff, so that they can monitor their activities in the hospital at any time, and such a technology is radio frequency identification technology (RFID).
Rob, the founder of SAVI in the United States, never thought that the tracking technology he developed would be useful today in the fight against SARS. In fact, he most hopes to solve the problem of his young son running in the supermarket because he often gets lost. , This makes Rob feel a headache. So he thought, if you put an electronic tracking device on the child, so you can clearly know the whereabouts of the child, then Rob immediately established the SAVI company, and developed related products of radio frequency identification technology.
But later, SAVI never put radio frequency identification tags on any children, because they were supported by the US Department of Defense and began to use radio frequency identification technology extensively in military, medical and disease control.
Disease control tracking
The biggest advantage of RFID smart tags lies in the control of disease management conditions, which has great convenience, such as the prevalence of terrifying infectious diseases such as SARS, mad cow disease, and avian flu some time ago. Or it has convenient control in the patient management application in the nursing ward or emergency room whose life is threatened. The hospital can track any new medical records in time, and can also detect a series of current conditions of the patient.
The United States and Europe are using electronic tag technology (RFID) to monitor mad cow disease, thus providing a new technical guarantee for the public’s food safety. By implanting RFID tags on the cow’s ears, the cow’s detailed information, such as its breeding status, age, weight, and disease treatment, can be recorded. These RFID tags are actually a tiny computer chip with an antenna installed, which can be automatically read, and can use wireless transmission to send these data directly to the computer database. RFID disease condition monitoring and management can provide location information of all personnel in contact with suspected cases, so as to facilitate accurate and timely isolation of personnel.
Medical system management
Use RFID for internal management of the hospital, such as: drug administration, blood transfusion, patient identification, management of the emergency room (operation theatre) of the hospital, and regulation of medical staff, various operations The collection of equipment and information around the operation is a good tool for hospital management.
Medical supplies management
RFID can be applied to the management of the supply chain of medical supplies, with the performance of tracking items, and timely and accurate control of the inventory of items, such as the personnel control of the access of medical items, the management of the quantity and storage location of medicines, and the monitoring of the safety period of medical items Wait.
According to a report by the US “World Journal”, the US Food and Drug Administration recommends the use of new technologies to ensure the safety of the US drug supply, including the use of packaging that makes it easy to detect that the drug has been manipulated, and the use of electronic labeling technology to track the drug from the drug factory to the drug factory. The bureau’s process helps prevent criminals from mixing counterfeit drugs in the delivery process.
Smart label system includes
Smart Tag (Tag)
The smart tag is worn by medical staff or specific personnel, and can grasp the complete movement information of the personnel in the hospital by the induction record of the smart tag and the RFID control management system.
Smart label receiving device
The reading device that prompts the smart tag to issue the code and location of the wearer can be installed in every place in the hospital. The reading device receives the signal sent by the smart tag, and the recognition rate can reach more than 50 per second.
Control and management computer system
The application side can use encryption and decryption methods to achieve the effect of confidentiality, and can quickly record the obtained signals in the database, and quickly find the target trend that is sought from the records of the database.
Medical staff wear smart tags.
The smart tag sends the personnel location and personnel information to the reader.
The reader sends information to the sensor system for storage.
The application system can query the action records of each member at any time, and provide timely monitoring information for the hospital.
Application of implantable RFID smart label
Implantable RFID smart tags are as big as rice grains, but each tag has a unique authentication number, which can be scanned to obtain disease information. Due to its small size, it can be implanted in the patient’s skin. This passive patient implantable RFID smart tag can be connected to existing electronic medical records via telephone lines, networks or hospital area networks, which is very convenient in use. The current applicability of implanted smart tags (patients implanted RFID) has been greatly improved.
Medical information management
Place the RFID smart tag on the “medical care card” card, the tag can record the patient’s own complete medical records. Any doctor or other medical staff can instantly read and store critical medical record information. In this way, it can promote individuals to get good care and accurate diagnosis wherever they are.
