With the continuous improvement of the medical system today, the degree of informatization of hospitals has been greatly improved. Nowadays, large hospitals have already used the Hospital Information System (HIS). After the application of the HIS system, it is convenient for the masses to seek medical treatment and has also improved. The level of medical service.
However, some problems in the current HIS system have not been fundamentally resolved. For example, when encountering an emergency and facing a patient who must be rescued in time, doctors and nurses must first look for the patient’s case, check the patient’s medical history and the history of drug allergy, etc. Important information will be promptly rescued in response to the situation, but these will delay the best time to rescue the patient. RFID solves all your troubles.
When the hospital adopts the RFID system, these problems will be solved. Every hospitalized patient will wear a wristband with RFID technology. The relevant information of the patient is stored here, including basic personal data and important information such as the history of drug allergy. More detailed information can be mapped to the database through the electronic code on the RFID electronic tag.
In the existing HIS system of the hospital, the basic information of each registered patient has been entered, but this information does not follow the patient from time to time. Only the medical staff can check the patient’s accurate information before the computer terminal in the office area. Now, through a simple RFID smart wristband, medical staff can grasp the accurate information of every patient anytime, anywhere.

As can be seen from the above figure, the final complete patient case is stored on the hospital server, and the RFID handset of each ward doctor can also store the relevant case of the patient in charge, and the relevant case on the patient’s wristband can be accurately read through the handset. Information, and can also be written into corresponding information, such as: whether the patient is allergic to a certain drug, whether he has received an injection today, whether he has taken a drug today, etc. Monitoring information, which greatly improves the efficiency of hospital management of patients. RFID technology can Completely replace the patient information card in front of the existing hospital bed.
In our daily medical activities, we do use patient identification all the time, including the use of bedside identification cards that record the patient’s condition, and allowing patients to put on hospital gowns and so on. Hospital staff often use words like “Patient in bed 10, take medicine” to guide patients to receive various treatments. Unfortunately, these methods often lead to wrong recognition results and even cause medical accidents. In fact, we have not really used correct and effective patient identification to reduce medical accidents and improve medical management.
The hospital’s clear identification of patients should follow the following three basic principles: provide accurate patient identification, and the identification is accurate and uniform, covering all relevant departments of the hospital; establish a clear correspondence between patients and medical files, and various treatment activities; reliable use The identification products to ensure that the patient identification will not be exchanged or lost.
By using a specially designed smart-Wrist, the identification belt marked with important patient information is tied to the patient’s wrist for 24-hour personal identification, which can effectively ensure that the patient can be identified quickly and accurately at any time. At the same time, the specially designed patient identification belt can prevent being replaced or removed, ensuring the uniqueness and correctness of the identification object.
We also recommend that hospital staff also wear badges with RFID technology, so that the hospital can not only manage patients, but also find the doctor who needs it most in times of emergency.
Advantages of applying RFID:
◆Help doctors or nurses to confirm the identity of patients with communication difficulties.
◆Monitor and track people who enter high-risk areas without permission.
◆When medical emergencies, epidemics of infectious diseases, terrorist threats and other situations pose a threat to the normal and effective work of the hospital, the RFID system can promote the implementation of restrictive measures to prevent unauthorized medical care, staff and patients from entering and leaving the hospital.
◆The wristband allows the hospital administrator to encrypt part of the data, so that even if the wristband is lost, it will not be cracked by other personnel.
Application of RFID in maternal and infant identification
In addition to the application functions we mentioned above, RFID wristbands can also be used in many aspects of hospitals, such as mother and baby identification.
Who are the patients who cannot accurately express their condition? That’s right, it’s a newborn. Newborn babies have similar characteristics and lack understanding and expression skills. If they are not effectively marked, they will often cause misidentification. Therefore, the identification of newborns is extremely important. The mother and the baby are a pair, and there are management loopholes in the identification of the baby alone, and malicious human exchange cannot be prevented.
At present, the hospital has problems such as the mother holding the wrong baby and the baby being stolen. How to effectively avoid this problem is to add RFID technology to the existing management software, including wristbands, handheld readers, and access control systems.
As shown in the figure above, when the nurse is holding the baby and leaving, the identification information of the baby’s wristband must match the mother’s identification information to leave. If the information does not match, the access control system will issue an alarm, which can effectively prevent the baby from being carried by mistake.
To prevent the baby from being held by mistake:
Through the handheld RFID reader carried by the nurse, the information in the RFID mother-infant identification belt worn by the mother and the baby is read respectively to confirm that the identities of both parties are matched, and to prevent babies who are about the same length at birth from being held by mistake.
Baby anti-theft:
It is necessary to arrange fixed RFID readers at the entrances and exits of each intensive care unit. Every time a nurse and baby need to pass, by reading the RFID identification card on the nurse and the RFID mother-infant identification tape on the baby, the identity is confirmed and monitored. The door of the ward can be opened. At the same time, the nurse’s identity information, the baby’s identity information and the time of entry and exit are recorded in the database. With surveillance video, security guards can monitor the situation in key areas at any time.
In addition to greatly reducing the possibility of the baby holding the wrong baby, the hospital can also bring some benefits through the RFID wristband. For example, sell RFID wristbands with names, dates of birth, portraits, etc. to pregnant women.
