1. Project background
After more than 40 years of construction, a third-class hospital in a city has developed into a large-scale comprehensive hospital with complete disciplines, strong teachers, superb medical technology, advanced diagnosis and treatment equipment, and strong scientific research capabilities, integrating medical treatment, teaching, scientific research, and preventive health care. .
The hospital covers an area of 78 acres, has 1302 beds, 23 clinical departments, 2 national key disciplines, 12 provincial and municipal key departments, 17 provincial and municipal research institutions and technical centers, and provincial and municipal innovation teams 2 One, 4 peripheral branches;
The obstetrics department of a tertiary hospital in a certain city is one of the key departments of the hospital, and the safety of infants in hospital has always been concerned by parents and hospitals.
Second, the significance of the construction of the baby anti-theft system
In recent years, incidents of domestic newborn babies being lost and stolen in hospitals have frequently occurred. Traditional baby monitoring management is usually performed by manual care management methods that use visually recognizable characters, barcodes, and cards to identify. This management method is often prone to misidentification. This led to the occurrence of exchanges and thefts, which brought huge losses and impacts to the hospital and family members.
Here we propose a new kind ofRFID The technical application design of neonatal electronic anti-theft system, because RFID has the characteristics of long-distance non-contact fast and accurate reading, it is very suitable for reading and monitoring neonatal characteristic information.
2.1. Supervise and manage newborn babies in the hospital in the hospital;
2.2. Active early warning, solve the problem of lagging accidents, expose the hidden dangers of accidents in advance, and avoid accidents;
2.3. Reduce the workload of the hospital nurse doctor’s management and improve work efficiency;
2.4. Improve the informatization level of the hospital, promote the institutionalization, standardization and real-time development of the hospital’s infant management work, and ensure the safety and stability of the delivery room.
3. Introduction to Baby Anti-theft System
Anti-dropping as a wrist strap andelectronic labelAfter connecting and using, the system function is activated. When the wristband and tag are completely detached from the baby’s body, the human body sensing system of the electronic tag will work and an alarm will be issued to ensure that the baby is within the protection range of the system.
Anti-theft RFID card reading network is deployed throughout the monitoring area. When the tag and wristband worn by the baby are removed, the system generates an alarm. Install readers at the regional boundary. When a baby wearing a tag is illegally carried out without being authenticated and checked out by the system, and passes through the regional boundary, the system generates an alarm.
When a parent is discharged from the hospital, the system will require the operating doctor or nurse to strictly check the baby’s information, and use the wristband worn by the baby and the baby’s mother’s ID number to ensure that there is no wrong hold; first, the baby’s wristband There is a unique serial number. If the serial number on the wristband is inconsistent with the serial number of the wristband worn by the baby at the time of discharge, the discharge cannot be processed. Second, the system also requires the baby’s mother’s ID number to be entered when leaving the hospital. If the number is incorrect, it will not be possible to go through the discharge procedures.
When the baby is admitted to the hospital and wears the baby tag, the system performs real-time protection; when the baby is discharged from the hospital, the medical staff performs relevant operations and accurately checks and enters the relevant information. The system releases the protection, and the parents can hold the baby and leave the hospital smoothly; when the baby needs to be temporarily discharged When leaving the monitoring area, the medical staff will perform a temporary check-out operation; when the baby returns to the monitoring area, the medical staff will perform the check-in operation again.
System flow
3.1. Infant admission registration
When a baby is born or admitted to the hospital, he must wear the guard tag provided by the baby anti-theft system on the baby’s ankle or wrist before admission, and record the mother and baby’s relevant information in the system, such as the baby’s bed, gender, name, mother’s name, and phone number , ID number, bed information, etc.
3.2. Real-time monitoring of baby status
The red dot baby anti-theft system monitors the baby’s status in real time, and displays it in graphical or tabular query mode. Specifically, it includes the baby’s current location, status, alarm information, etc.
3.3, APP software baby status implementation reminder
The red dot baby anti-theft system provides mobile phone APP software support. Each guardian can log in through the mobile phone number and baby wristband number provided when the baby is admitted to the hospital. When the baby’s status changes, the mobile phone terminal will always prompt, and the APP software also provides Authoritative nursery expertise and expert Q&A.
3.4. Infant out of bounds alarm
For infants who have not gone through the procedures for discharge or temporary leave, the system will issue an alarm signal when they approach the border of the guarded area.
3.5. Label destruction alarm
If the baby’s electronic tag is violently damaged or removed, the system will automatically call the police to prevent criminals from damaging the wristband tag to get the baby out of the guarded area and carry the baby away.
3.6. Baby changing bed function
The system provides a bed changing function to cope with the possibility that the baby may change bed during the hospitalization period.
3.7 Temporary entry and exit of infants
In order to solve the problem that babies need to leave the guarded area temporarily due to inspection, treatment, bathing, etc. during the hospitalization period, the system provides temporary access functions.
3.8. Unique baby wristband serial number
The red dot baby anti-theft system has a unique baby wristband serial number, which can uniquely identify the baby after being bound to the system to prevent the occurrence of holding errors. At the same time, it can also identify the baby at a glance.
3.9. System query tracking function
The system provides a variety of query and retrieval methods to satisfy the hospital’s tracking and query of babies, mothers, and the operating process of the system.
Fourth, baby anti-theft system deployment
The Red Dot Baby Anti-theft System is an independent system placed in the obstetric ward. In the obstetric ward, RFID technology is used to build a safe protection area. No matter how the baby leaves the safe area, the system will immediately call the police. The deployment will not affect any of the original systems of the top three hospitals in a certain city. At the same time, the alarm device of the baby anti-theft system can also be connected to the security system of a tertiary hospital in a certain city to maximize the protection of the common interests of infants, their families and the hospital.
The specific deployment is as follows:
Five, the system requirements and configuration parameters of baby anti-theft
5.1. System technical requirements:
5.1.1. Baby anti-theft labels and wristbands
From the moment the baby anti-theft tag is activated, the electronic tag continuously automatically emits radio frequency signals, which are received by the receiver and transmitted to the system server via the network. If the tag cannot be detected within a period of time (the length of time can be flexibly set in the system management software), the system will generate an alarm. The tag should have a reliable anti-vandal mechanism. When the tag and the anti-vandal wristband are worn on the baby After that, the mechanism was fully activated immediately. Unauthorized attempts to remove the tag will trigger an alarm. The wristband used with the label can be adjusted to suit different babies.
★Due to the limitation of the working environment such as the delivery room, the label must be completely worn on the baby’s hand or foot each time before the admission procedure can be processed to prevent the label from being caused by the negligence of the staff after the admission is not processed in time. If it is not activated or is not properly worn after activation, the baby will leave the protection state to ensure the safety of the system.
★Baby anti-theft labels should be specially designed for newborn babies, and the weight should not be greater than 12 grams. In order to protect babies from electronic radiation hazards, the transmitting power of the tag is less than 100μw (10-4w).
★The label must have the baby’s skin sensing function to ensure that the anti-theft label is always safely worn on the baby. Whether it is accidentally or deliberately removed, if the label cannot sense the baby’s skin within a period of time (the length of time can be flexibly set in the system management software), the system should promptly check the tightness of the label and when the label falls off Alarm, the system software automatically records events and alarms.
★When the wristband used in conjunction with the label is cut, the alarm time should be less than 0.5 seconds.
★The label adopts waterproof design, no allergic reaction, and can be easily cleaned. It does not need to be removed during the normal hospitalization period, and it does not affect the daily cleaning and nursing care of newborns such as bathing and swimming.
★The tag must send out the heartbeat signal in real time, and the system will alarm immediately when the heartbeat signal of the tag is not detected.
★The label battery must be guaranteed to be used for more than one year. When the label power is too low, the system can take the initiative to give an alarm and prompt to replace the battery. There is no need to check one by one on a regular basis.
★All hardware devices designed by this system must have an automatic diagnosis function. When the system hardware device fails, the system automatically prompts to ensure the safety of the system itself.
★The baby wristband must have a unique serial number to identify the baby when it is discharged from the hospital to prevent the baby from holding the wrong baby.
★The system has the function support of APP software to provide patients with more effective reference.
5.1.2, IoT card reader
The IoT card reader is installed in a protected baby-friendly area and can receive signals from anti-theft tags within a circular range of about 10-12 meters in radius. Multiple IoT card readers form a receiving network. The IoT card reader has a unique network address code. It communicates with the existing baby anti-theft system server through the network and accepts system monitoring. No matter what causes the IoT card reader cannot work normally, it should be detected by the system immediately Arrives and generates an alarm.
5.1.3, IoT alarm
The Internet of Things alarm is installed at the exit of the obstetric ward, and forms a network with the Internet of Things card reader to form a security boundary. The detection area of the IoT alarm can completely cover all exit pathways, forming a complete exit barrier for obstetric wards, ensuring that babies will not be taken away illegally. Once the baby anti-theft tag enters the detection area of the IoT alarm, the tag that receives the alarm signal will immediately send alarm information to the system server through the IoT alarm.
The Internet of Things alarm should also have an interconnection interface with the camera and the access control system to provide support for the future expansion of the system.
The exit alarm response time of a single tag should be less than 0.2 seconds. This response time should not be affected by the number of tags in the exit area. Even if the number of tags is significantly increased to 20 or more, the response time must still be less than 0.5 seconds.
5.1.4, nurse workstation and management software
The nurse workstation monitors and coordinates the operation of the entire system. It processes all the data of the system. The system software records all system activities, including alarm information, in the SQL Server database. Various reports about system activity information can be consulted and printed out, and users can also customize the report content.
5.2, software part
5.2.1. The label must be able to automatically log in to the system
Every time the tag is worn on the baby, it must be able to automatically log in to the system to receive protection immediately after activation, ensuring safety and reliability, and reducing the burden of nursing work.
5.2.2. Baby anti-theft tags must have baby skin sensing function
The label should have a baby skin sensing function to ensure that the anti-theft label is always safely worn on the baby. If the label falls off accidentally or is removed deliberately, if the label cannot sense the baby’s skin within a period of time (the length of time can be flexibly set in the system management software), the system should promptly check the tightness of the label and Alarm when the label falls off, the system software automatically records events and alarms.
5.2.3, low voltage reminder and battery warranty
The label battery must be guaranteed to be used for more than one year. When the label power is too low, the system can take the initiative to give an alarm and prompt to replace the battery. There is no need to check one by one on a regular basis.
5.2.4. Floor plan management
The management software must be able to display the floor plan, and the location of all system equipment can be marked on the map. When an exit alarm is generated, the specific alarm location can be immediately displayed on the map.
5.2.5. The system must provide a temporary label check-out function
The anti-theft label temporary check-out function temporarily disables the system protection of the anti-theft label without removing the anti-theft label. The duration can be flexibly set as needed, and the label does not generate any alarm during this time. The system provides a countdown function for each temporarily checked out label. This function is used by the nurse to carry the baby away from the baby-friendly area to perform special nursing work when necessary.

6. Investment income of baby anti-theft system
Two models of infant anti-theft system construction are given to customers, as follows:
6.1. Self-built hospital
The infant anti-theft system is based on the ward. The ward refers to the area between two or N staircases as the ward. The software and hardware investment of the infant anti-theft system in each ward is 300,000 yuan. The baby label needs to be replaced every year 980 yuan/piece*50=49,000 yuan/year, and the system maintenance cost is 300,000*10%=30,000 yuan/year.
If 400 babies are born every month, the cost of the wristband to enter the hospital is 90 yuan, and the retail price of the patient is 150 yuan, then 400 * (150 yuan-90 yuan) = 24,000 yuan / month * 12 months = 288,000 yuan / year.
The annual net income is 288,000 yuan / year-49,000 yuan / year-30,000 yuan / year = 209,000 yuan / year.
6.2. Investment and construction
If you invest in construction, according to the above calculation, it will take 2 years to recover the cost. After the cost is recovered, the baby anti-theft system belongs to a third-class hospital in a certain city. The hospital in a certain city accounts for 80% of the income of all infant wristbands and the investor accounts for 20%.
After the one-year free service period, the annual system upgrade and maintenance costs are 10% of the contract amount.
