What is RFID technology? The role of RFID technology in smart medical care
RFID technology is a radio frequency identification technology, and its basic composition includes a transponder and a reader. The transponder is usually made into a tag style, that is, an RFID tag, which can be easily attached to an object or person. The reader is responsible for reading and writing RFID tag information, generally there are handheld RFID readers and fixed readers.
Smart medical care involves big data, the Internet of Things, mobile information and even cutting-edge technologies in biochemistry, as well as related infrastructure. RFID belongs to the category of the Internet of Things. Due to its advantages such as accurate and fast information reading and storage, convenient and quick operation, and automation, RFID technology plays an important role in the construction of smart medical care. Mainly include instruments and items, and drug management, identification, labeling and tracking, inventory management, asset management, and personnel management. Today only talk about the application of RFID technology in hospital staff management.
Why does the hospital need to do personnel management?
A hospital is a complex place with a lot of people, especially a big hospital. Unlike many institutions, where there are only staff members, in addition to busy doctors and nurses, there are also many newly born children, patients with special illnesses and other vulnerable groups, as well as children and relatives of people with illnesses. When there is an accident or misfortune, there will be emotionally unstable victims’ families gathered here. Therefore, the hospital is a place where people are chaotic but not chaotic. Moreover, newborn babies are stolen, and the hospital is chaotic in emergencies. Such phenomena also occur from time to time, so effective personnel management is necessary in the construction of smart medical care.
How does RFID technology manage personnel?
Staff management such as doctors and nurses:
l Set up RFID access control and attendance channels, and medical staff wear corresponding RFID employee cards. The RFID attendance channel automatically recognizes the RFID cards of medical staff and automatically completes the management of attendance records.
l Separate RFID access control is set up for special and important areas to perform permission detection and entry and exit records for entering employees.
l Security personnel patrol location and route management records. Security personnel wear RFID tags that can be located, which can monitor the activities of security patrol personnel. In important places, patrol personnel can be identified and confirmed through RFID reading and writing equipment.
Management of patients with special diseases:
Wear RFID tags for special patients, you can monitor their activity area, and the patient can alarm when entering non-authorized areas
Newborn baby management:
It is not easy to distinguish newborn babies from the appearance, and newborn babies do not have the ability to communicate, which can easily cause confusion. There are even criminals who steal newborn babies. Therefore, it is extremely important to prevent theft in the management of newborn babies.
Employees, mothers and family members, and visitors who first enter the newborn baby area must wear RFID tags with identification information, and set up RFID channels on the channels to record and monitor the information and activities of each person who enters and exits.
Secondly, the newborn baby wears the RDID tag containing the newborn baby information at birth, and the newborn baby’s RFID tag is associated with the mother’s RFID tag. The mother and the newborn baby have the same identification to prevent artificial replacement and activities of the newborn baby. The range is monitored, and an alarm is issued when it exceeds the range.
Third, if the RFID tag worn by the newborn baby adopts anti-tear and anti-vandal technology, if it is forcibly torn off or damaged, an alarm will be issued and the current location will be located.
Fourth, if criminals attempt to steal the newborn baby, the background system can immediately lock the location of the personnel entering and exiting, as well as the location of the newborn baby.
Emergency management of major accidents:
When a major accident occurs, a large number of victims often enter the hospital and require first aid. Confusion is often easy at this time. At this time, RFID tags can be worn to each patient to record the patient’s condition information, treatment information, etc. During follow-up treatment and dressing change, medical staff can use RFID readers to quickly verify and identify information to avoid human errors (such as misidentifying the wounded, mistaking medication time, etc.).
Can be used as RFID tags and chips for personnel management
RFID tags:
The label form can be made according to different needs and packaged in different packages. The common ones are card type (worn by staff and visitors), wristband type (worn by patients), etc. For special patients and newborn babies, it should be made Special label.
RFID chip:
The chip can be divided into RFID reader chip and RFID tag chip, the working frequency is 13.56MHz.
RFID reader chip:
Support the contactless reader mode that complies with ISO/IEC 14443 Type A protocol. And has low voltage, low power consumption, strong driving ability, multi-interface support, etc.
Its characteristics are: support M1 encryption, support communication rate 106kbps, 212kbps, 424kbps, 848kbps, reader operating distance up to 50mm (depending on antenna design), support multiple host interfaces, SPI interface up to 10Mbps, I2C interface supports up to 400Kbps The fast mode, and the highest 3.4Mbps, high-speed mode, serial UART interface, support RS232 frame format, the highest communication rate 1.2Mbps, built-in CRC coprocessor, etc.
Feiju RFID reader chip
A dual-interface RFID tag chip suitable for monitoring and step counting for personnel management:
The dual-interface RFID tag chip suitable for personnel management supports both non-contact and contact interface communication. In addition to the NFCtype2 RF interface, it also has an I2C contact interface. The contact interface can be used to communicate with an external MCU. Using the communication between these two interfaces, fast data exchange between the interfaces can be realized. The communication between these two interfaces can use the internal integrated SRAM as a data buffer, not necessarily limited to EE memory.
