Preface
Nowadays, the application of RFID in the medical industry is not limited to hospitals, but goes further to the outdoors, with wireless broadband transmission technology, so that mobile medical care is as orderly as in a hospital. In the future, in any corner of Taiwan, if there is a serious and widespread disaster like the August 8 Flood, the rescue team will be able to save more precious lives during the golden rescue period.
A few years ago, when RFID technology just emerged and it hasn’t been widely used in general enterprises, the application of RFID in the medical industry is quite extensive. In emergency rooms and operating rooms, RFID is used for patient identity management; through RFID-assisted “three readings and five pairs” in such links as medical consultation, surgery, and medication, it can make up for possible negligence in manpower operations. It is indeed for improving patient safety. Great help has been produced. In recent years, active RFID, which can send out signals, has also entered hospital wards and is used to track dementia but still capable elderly patients to avoid danger.
RFID goes out of the hospital and is implemented in mobile medical
Nowadays, the application of RFID in the medical industry extends from inside the hospital to outside the hospital. The Department of Health of the Executive Yuan promoted a disaster prevention and emergency medical response system in 2000, and established a national disaster medical rescue team in the south and north of Taiwan, and established detachments in various regions. The affiliated hospital of the National Cheng Kung University School of Medicine in the Southern District (hereinafter referred to as Chengda Hospital) is one of the detachments of Taiwan’s national disaster medical rescue team and is also responsible for the tasks of the Southern District Executive Center. When an emergency disaster occurs in the local area, the emergency medical response centers set up in each district accept the command of the local health bureau, station in the disaster area, conduct emergency medical rescue nearby, evaluate the needs of the scene, and determine the dispatch of personnel and resources.
When it comes to emergency rescue operations, the general public is mostly concerned about search team rescues. However, in the early stages of major disasters, if emergency medical response is appropriate, the number of people that can be rescued far exceeds that of search and rescue operations. In order to increase the efficiency of disaster rescue, in addition to continuing to enrich professional disaster medical training, National Cheng Kung University Hospital has recently introduced a mobile medical system, hoping to use the identification and recording function of RFID to truly grasp the status of all the injured and patients, so that the number of people rescued will be extremely large. change.
Xinji Information and Juhao Technology are the main partners of the National Cheng Kung University Hospital’s emergency rescue system. The two companies provide peripheral equipment such as handheld PDAs and barcode printers for the system. In addition, in order to make mobile medical services smoother, Chengda Hospital has developed a completely independent emergency relief system for medical records in the disaster area.
Emergency room in the disaster area to keep rescue operations in an orderly manner
When the disaster occurred, the emergency rescue team received the message as soon as possible, and the ambulance and the medical personnel on board were dispatched immediately. After arriving in the disaster area, when the first-line first responders came into contact with the patient, they put on an RFID wristband and recorded the patient’s injury level, type of injury, condition, and other information. After preliminary treatment, transfer Introduce to the second-line professional medical staff. Medical staff scan the patient’s wristband with a handheld PDA, obtain the data index in the wristband, and perform medical actions such as diagnosis and prescription according to the injury status.
The doctor can directly write down the medical advice after diagnosis in the handheld PDA, enter the name of the medicine to be taken, and proceed to prescribe the medicine. Lai Jinyi, Regional Business Director of Xinji Information Marketing and Business Division, pointed out that the data between the patient’s wristband and the emergency relief system can be quickly transmitted through WiFi wireless network or 3G mobile network to construct a mobile medical network. The order of emergency procedures is equivalent to transplanting the hospital emergency room directly to the disaster area.
The bracelet used in the emergency rescue system is equipped with barcode and RFID tags at the same time. Lai Jinyi said that if you are in an indoor courtyard, just relying on a barcode for identification is roughly enough, but the disaster areas are mostly located in outdoor environments, and if it is a natural disaster, the scene is usually heavy rain, muddy, and messy.
Traditional bar code bracelets are very likely to be unreadable due to dirt or damage. Therefore, the emergency rescue system is additionally equipped with RFID tags to allow the two identification modes to be paralleled to increase the reliability of the system. The induction coil wrapped in the RFID tag in the plastic can ensure that the bracelet can still be read by the handheld PDA under various harsh conditions when the bracelet is damaged by force majeure. It can be effective in emergency situations where every second counts. Reduce the time for doctors to repeatedly inquire about the patient’s condition.
When a large-scale disaster occurs, it often causes hundreds or thousands of injuries and patients. At this time, the work of the emergency rescue team to identify patients is particularly important. It is recorded that the second-line doctors on the team can take over the treatment immediately and do not need to spend extra time to understand the condition.” Lai Jinyi believes that after a huge natural disaster, the golden rescue period is very limited, and the speed of medical behavior will be straightforward. Affect the efficiency of rescue.
RFID blessing, medical industry applications are more abundant
At this stage, the application of Chengda Hospital’s emergency rescue system is only a small-scale demonstration. However, the mobilization of medical procedures has already made preparations for the future of cloud medical care. In the future, when the electronic medical record system is officially launched, the medical records of various hospitals can be exchanged with each other through the system. The emergency rescue system constructed in the disaster area can also be used and secured by the broadband network to match the existing National Cheng Kung University Hospital. HIS systems are connected in series. The medical staff in the disaster area can learn from the cloud at the same time of treatment that the patient’s physiological data and medical history at different periods will help the appropriateness of the current diagnosis and treatment.
In all respects, RFID is very suitable for use in the medical industry. RFID tags are reusable and can be read without barriers. In addition, RFID tags have high storage capacity; compared with 2D barcodes that can only hold 3,000 bytes of data, RFID tags can store up to millions of bytes of data In addition, electronic messages are not easy to be cracked and have sufficient security. It can provide adequate protection when storing highly confidential personal medical records. The closer integration of RFID and medical procedures, and the business opportunities presented after the integration, will be just around the corner.
