With the advancement of technology, this problem finally has a complete solution. Shenzhen Yuanwei Electronics Co., Ltd. uses the world’s leading active RFID technology to design a complete system solution. Use the monitor, locator and tag in the active RFID product to form a strict real-time monitoring system inside the hospital. Ensure the safety and correct identification of newborn babies.
solution
v There are many disadvantages in the existing traditional baby management methods in hospitals:
v 1) In the baby logo, use cloth tapes of various colors that can be untied repeatedly, or tape with baby’s name written on the baby’s forehead, or baby wristband with baby’s name written on it, and the mother and baby logos are different and irrelevant, etc. These signs are often not easy to be waterproof, easy to fall off, and can also be manually unlocked; accidents such as theft of babies, malicious exchanges, and medical care mistakes cannot be detected and prevented in time.
v 2) The inability to accurately identify, check the baby’s identity, and the relationship between the baby and the parent’s identity at any time, present opportunities for malicious and unintentional exchange of babies, and cannot be accurately handed over when the baby is discharged from the hospital.
Shenzhen Yuanwei Electronics Co., Ltd. uses the world’s leading active RFID technology to solve your problems. In the main location of the hospital, a series of monitors and locators are installed. These monitors are connected to the computer system through the network. Pregnant women who entered the delivery room to prepare to give birth were put on an electronic wristband. At the time of delivery, babies who have just been delivered also wear an electronic wristband on their ankles or wrists. The electronic code in the child’s wristband immediately establishes a one-to-one correspondence with the electronic code of the mother’s wristband. The child is correctly identified and monitored at birth. The child’s movement anywhere in the hospital at any time will be received by the locator and monitor and sent to the computer system. Alarm devices at special locations such as doorways or passages will monitor any abnormal conditions.

Under normal circumstances, the movement of the child in the monitoring area must be monitored, such as moving with the mother or with the medical staff, if the child moves alone (carried away by unauthorized personnel) or the mother approaches or walks out without going through the discharge procedures Monitor the area and the system can alarm. To ensure the safety of the child, but also to ensure that the child will not be mistakenly held. The wristband is equipped with a human body sensor, which will send out an alarm signal when the electronic wristband leaves the body. For the system to recognize whether the removal of the wristband is an authorized behavior.

In order to meet the needs and development of the market, Shenzhen Yuanwei Electronics Co., Ltd. also introduced a child’s body temperature that can be monitored according to customer needs. Produce a baby wrist tag with monitoring function. With real-time monitoring of his body temperature, the child’s health is also protected accordingly.
