RFID applications in medical care

1. Medical monitoring

In many Hospitals, there are a large number of emergency patients every day, especially in some large emergency centers. When there is a collective accident, a large number of injured people will flood into the hospital. At this time, every minute and second is extremely precious, and there is no room for it. error. However, the condition of each injured person is very similar and can easily be confused. Traditional manual registration is not only slow and has a high error rate, but it is also impossible to register critically ill patients normally. In order to quickly confirm the identity of all patients, complete admission registration and carry out step-by-step follow-up first aid work, the medical department urgently needs an automatic identification system that can provide the identity and condition information of the injured in real time. Only in this way can hospital staff be efficient and Carry out rescue work accurately and orderly.

The specific application method is to wear a wrist tag for each patient. When the patient receives diagnosis and treatment, the medical staff only need to scan the tag information with a handheld reader to know the first aid matters that need to be carried out, such as whether infusion is needed, the name of the injection drug, Specifications, treatments that have been carried out, whether there are any adverse reactions, etc., all data will be displayed in front of medical staff in less than a second, so that they can check the medical care procedures and drug specifications, quantities, etc. Records of all treatment sessions and medication injections can also be Stored within the patient tag.

2. Newborn identification management application

Newborn babies have similar characteristics and lack of understanding and expression ability. If they are not effectively labeled, they will often be misidentified, resulting in irreparable and huge impact on all parties. Therefore, in addition to the function of patient identification, the identification of newborns must also realize the function of patient identification. At the same time, the mother and the baby are a matched pair. There are management loopholes in identifying the baby alone, and malicious artificial exchanges cannot be eliminated. Therefore, it is best to identify both the newborn baby and its mother, and use the same code to connect the biological mother and child. Infant care is between hospital staff and the mother, and during temporary transfers both parties should conduct checks simultaneously to ensure correct mother-infant pairing.

The mother and baby should be identified in the delivery room immediately after the baby is born, and the mother and baby should be transferred out of the delivery room before other patients are admitted. The delivery room must prepare: two non-transferable RFID (electronic tags, radio frequency identification) identification tapes, one for the mother and one for the newborn. The information on the identification tape should be the same, including the mother's full name and identification number, the baby's gender, date and time of birth, and other information that the hospital believes will clearly match the biological mother and child. A device that can clearly capture baby's footprints and mother's fingerprints. Appropriate forms are used to record relevant information and footprint information. In addition to marking, it can also fully ensure the safety of the marked objects. When someone attempts to steal a newborn out of a hospital ward, RFID (electronic tag, radio frequency identification) identification equipment can detect it in real time and issue an alarm, and notify security personnel of the latest location of the stolen baby.

3. Application for tracking and positioning of important hospital Assets and materials

Some large medical centers generally have huge storage bases of important medical assets and medical items. Hospital logistics personnel need to find suitable items from thousands of items according to orders every day. The outer packaging of medical items is usually similar, but the uses of the inner items are very different. Therefore, the hospital logistics department usually needs to spend huge manpower and material resources to find and check these items. Moreover, medical items must be stored in accordance with strict storage regulations. Misplacement incidents often occur during warehouse adjustments or when items are moved, resulting in extensive damage to items or serious drug accidents after they are distributed to the market.

The use of RFID (electronic tags, radio frequency identification) tags with LED lights will make the search and verification process extremely fast and accurate, and the tag itself can carry information related to the item, which can increase the speed of the entire verification process by about 20 times. In addition, if certain items are misplaced, the system can remind warehouse managers to adjust their storage locations through flashing LED lights.

4. Application of hospital contact tracing control

Combined with the infectious disease epidemic tracking and control system and the medical facility contact history RFID tracking and control system, various epidemic prevention and government units can instantly and accurately grasp the dynamic information of the entire treatment process, thereby preventing the recurrence of nosocomial infection control problems similar to the SARS epidemic. .

Infectious waste generated in home quarantine and medical facilities will be transported by dedicated garbage trucks for full tracking and control at the same time that the health unit issues a home quarantine notice. The relevant units can immediately know the whereabouts of the garbage trucks and report any abnormalities. It can be corrected immediately to prevent it from spreading. Most importantly, transparent dynamic tracking information can eliminate people's doubts.

5. Management application of pharmaceutical supply chain

In the medical field, a large number of errors in prescription, drug delivery and medication occur every year, resulting in many medical accidents, a lot of lost work time and legal litigation. According to statistics, the annual losses in these aspects are as high as 75 billion US dollars. Improved drug tracking methods may help hospitals save money and curb the proliferation of counterfeit and substandard drugs, which currently account for 10% of the global drug market.

Smart tags, or radio frequency identification (RFID), make it possible to identify physical objects at any point during the manufacturing and distribution process. RFID will play a key role in eliminating the often slow and inefficient sales and distribution processes and will help pharmaceutical companies prepare for the future, enabling them to produce a wider range of more complex products in smaller batches. . It can also help pharmaceutical companies meet increasing regulatory requirements by monitoring pharmaceuticals at all points along the supply chain, including precise batch loading.
