Radio frequency identification (RFID), also known as radio frequency identification, is a communication technology that identifies specific targets and reads and writes relevant data over radio signals without the need to identify the mechanical or optical contact between the system and a particular target . When the object to be identified into the magnetic field emitted by the reader when the electromagnetic induction, according to the energy emitted by the magnetic field and stored in the chip information (passive tag), or take the initiative to issue a signal of a certain frequency decoding by the reader To RFID software system (active tag). RFID technology has been widely used in hospital care in patients with basic information management, treatment management, drug release and use, medical advice information management, patient hospital management, patient tracking, and HIS system in the hospital data synchronization.
With the progress and innovation of nursing concept, the demand for home care and nursing care is increasing day by day. RFID technology has not only been used in hospitals, but also extended care services such as home and retirement, Elderly people are not hospitalized, timely tracking and care.
The United States applied radio frequency identification technology earlier in home-based care and successfully used RFID technology and robotics in combination with video technology. The initial robot was equipped with a video camera on the top and relied on the indoor mobility of the robot and the camera's viewability of the camera. The obtained images were processed by an A / D converter, Zig-Bee technology and sent over the Internet to their cell phones for monitoring Living conditions of the elderly. In addition to monitoring the robot now has the function of picking up the elderly, supporting the elderly to walk on their own, to help excretion, care dementia patients.
Asanga Wickramasinghe et al., A University of Adelaide, Australia, developed a wearable sensor that uses radio frequency identification (RFID) tagging technology to attach to the surface of the garment at the sternum. Its outstanding features are battery-less and light weight. These unobtrusive properties make this sensor particularly suitable for monitoring the actions of the elderly and analyzing the movement of the elderly after they get out of bed, and monitoring the elderly at home or in pension institutions as a key care strategy for preventing falls.
The Wi-Fi real-time location system at Josef Eck Pen's Geriatric Nursing Center in Neububede, Germany, simply needs to be wiped with Ekahau's Wi-Fi waterproof bracelet, beacon with bi-color LED and call button, except through personal Alarm triggering of the emergency switch, the B4Wi-Fi pager equipped with a staff member can be used to send an alarm to find out the location of the accident and the object to be monitored, and the application of the device and system to effectively help the aging institution to track and manage the patient so as to reduce the care The labor intensity of staff and improve the working efficiency of pension institutions.

Application of RFID Technology in Home Nursing Care

Japan RFID technology and the Internet docking, home care for the elderly to carry out remote monitoring, such as the elderly in the toilet, the smart toilet to check the elderly urine, blood pressure, body weight and fat, the measured data sent directly to the community health service center Elderly health records. Once the data is abnormal, Telemedicine will be started immediately. Or some elderly home equipped with a wireless fall detector waist, as long as a fall, the machine will issue a "Someone fall" voice prompts, and connect to the network service center, then the service center will quickly send to the elderly In view of the situation.
In the aspect of home-based care, the RFID tags are embedded in the articles used by the elderly in their daily life or the daily wear of the elderly, and real-time monitoring of some health indicators of the body is carried out. According to the feedback information of these electronic tags, the analysis and judgment are carried out. When a serious health problem occurs, a warning is issued by the radio frequency identification (RFID) platform in conjunction with the Internet information platform to warn the mobile phones sent to hospitals and other institutions and their children at the same time that precious time will be spent on caring for the elderly and saving the elderly.
