Overview

Today, with the continuous improvement of the medical system, the degree of hospital information has been greatly improved. Nowadays, large hospitals have used the Hospital Information System (HIS). After the application of the HIS system, it is convenient for the public to seek medical treatment and improve. Medical service level.

However, some problems in the current HIS system cannot be fundamentally solved. For example, when encountering an emergency and facing a patient who must be rescued in time, doctors and nurses must first search for the patient’s case, view the patient’s medical history and drug allergy history, etc. Important information is only necessary for timely rescue of the situation, but these will delay the best time to rescue patients.

When the hospital adopts the RFID system, these problems will be solved. Every patient in the hospital will wear a wristband that uses RFID technology. The patient’s relevant information is stored here, including basic personal information and important information such as drug allergy history. More detailed information can be mapped to the database through the electronic code on the RFID tag.

The hospital’s current HIS system has already entered basic information for each registered patient, but this information is not always followed by the patient. Only the medical staff can find the accurate information of the patient before going to the computer terminal in the office area. Now, through a simple RFID smart wristband, medical staff can grasp the accurate information of each patient anytime, anywhere.

It can be seen from the above figure that the hospital’s final complete case is stored on the server, and the relevant cases of the responsible patient can also be stored on the RFID handheld of the doctor in each ward, and the relevant information on the patient’s wristband can be accurately read through the handheld Information, and corresponding information can also be written, such as: whether the patient is allergic to a certain drug, whether he has been given an injection today, whether he has taken a drug today, etc. Monitoring information greatly improves the efficiency of hospital management of patients, RFID technology can Completely replace the patient information card in front of the existing bed.

In daily medical activities, we do apply patient identification at all times, including the use of a bedside identification card that records the patient’s condition, allowing the patient to wear in-patient uniforms, and so on. Hospital staff often use words like “Patient on bed 10, taking medicine” to guide patients to various treatments. Unfortunately, these methods often cause erroneous recognition results and even cause medical accidents. In fact, we have not really used the 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, various treatment activities; reliable use The logo product ensures that the patient logo will not be exchanged or lost.

By using a specially designed patient identification wristband (smart-Wrist), the identification band marked with important patient information is attached to the patient’s wrist for 24-hour personal identification, which can effectively ensure the rapid and accurate identification of the patient at any time. At the same time, the specially designed patient identification tape can be prevented from 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 doctors most in need in an emergency.

Advantages of using RFID

• Help doctors or nurses to confirm the identity of patients with communication difficulties.
• Monitor and track people who enter into high-risk areas without permission to hang out.
• When medical emergencies, infectious disease epidemics, terrorist threats, and other conditions 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 people.

Application of RFID in maternal and child identification

In addition to the application functions mentioned above, RFID wristbands can also be used in many aspects of hospitals, such as maternal and child identification.

Who is the patient who cannot accurately express his condition? Yes, it is a newborn. Newly born babies have similar characteristics and lack of understanding and expression skills. If they are not effectively marked, they will often cause false recognition. Therefore, the identification of newborns is still important. The mother and the baby are a pair. There is a management loophole in the identification of the baby alone, and it is impossible to prevent malicious artificial replacement.

At present, there are problems in the hospital that the mother holds the wrong baby and the baby is stolen. How to effectively avoid this problem is to add RFID technology to the existing management software, including wristbands, handheld readers, access control systems, etc.

As shown in the figure above, when the nurse is carrying the baby away, the identification information of the baby’s wristband must match the mother’s identification information before leaving. If the information does not match, the access control system will issue an alarm, which can effectively prevent the baby from being mishandled.

To prevent the baby from being held wrong:

Through the handheld RFID reader carried by the nurse, the information in the RFID mother-infant identification band worn by the mother and the baby is read separately to confirm that the identities of the two sides match, so as to prevent the babies of the same age from being born from being wrong.

Baby anti-theft

It is necessary to arrange fixed RFID readers at the entrance of each intensive care unit. Every time a nurse and a baby need to pass, by reading the RFID identification card on the nurse and the RFID mother and child identification tape on the baby, the identity is confirmed after monitoring The door of the ward can be opened. At the same time, the nurse’s identity information, baby’s identity information and access time are recorded in the database. With the surveillance video, the security guard can monitor the situation in key areas at any time.

In addition to greatly reducing the possibility of infants holding the wrong, the hospital can also bring some benefits through RFID wristbands. For example, the RFID wristband is engraved with the name and date of birth and sold to the mother.
