1. System overview
At present, most obstetrics and gynecology departments in hospitals generally use marking rings for mothers and babies until they are discharged from the hospital to identify mothers and babies. This marking ring is a purely physical medium and can be easily exchanged. The existing management system of the hospital will not allow the family members who visit the baby to enter and limit the number of people, and control the casual entry and exit of the idle personnel. Even so, due to the eagerness of family members to visit mothers and babies, it is difficult to manage them in practice. How to solve the baby’s theft and prevent errors is a technical problem urgently needed to be solved by the obstetrics and gynecology hospital.
Therefore, according to the actual situation and management needs of the hospital, the hospital mother and child RFID wristband management system designed with advanced Internet of Things technology is based on the principle of openness, which supports both centralized management and humanized services, which is in line with the current and Solutions for future development. It will play an important role in the management of maternal and child identification, infant anti-theft management, and access authority management in the obstetrics and gynecology department of large general hospitals or women and children’s hospitals.
2. System structure
The system construction involves four parts: wristband label binding and information entry, real-time monitoring platform, system security management, and HIS management system interface.
Maternal and infant binding configuration management system: provide electronic wristbands for newborn babies and new mothers, bind the unique codes of the electronic tags of both parties, and provide comprehensive query functions for alarm events, nursing records, etc.; real-time monitoring platform: real-time platform Collect the wristband signals of each signal detector, and analyze the alarm events according to the preset monitoring logic, and immediately alarm when abnormalities occur; system security management: provide basic data, permissions, alarm event configuration management and other functions of the internal system; HIS management System interface: The basic information of mother and baby will be obtained from the HIS system first, and some nursing orders can also be synchronized to this system.
2.1 Software platform
The identification of newborns must not only fulfill the function of patient identification, but at the same time the mother and the baby must be matched, the baby also needs to be matched with the nursing staff. There are management loopholes in the identification of the baby alone, and malicious human exchange cannot be prevented. 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. During the temporary transfer of baby care rights between hospital staff and mothers, both parties should conduct inspections at the same time to ensure the correct mother-child pairing, and at the same time ensure that only matched medical staff have the right to carry the baby out of the safe area.
2.2 Hardware equipment
The hardware of the hospital maternal and infant RFID wristband management system is mainly composed of the following parts:
Anti-theft tag: This tag can be identified from a distance. Infants and mothers use wristband tags, and nursing staff can wear card tags;
Exit detector: a label signal collector installed at the main entrance;
Signal detector: a tag signal collector installed in the ward;
Control host (PC) and monitoring client: installed in nursing workstations, security monitoring centers, and mothers’ wards.
The four major system components can form a strict security network system. With the movement of the anti-theft tags, the system provides real-time alarms in areas where the anti-theft tags (irreplaceable) are not allowed to move or pass or stay. The cause of the alarm and related information.
Three, system function
1) Wristband management
It provides functions for issuing, binding and maintaining baby wristbands, mother or family wristbands, and nursing staff tags, and establishes exclusive archives of electronic tags for newborns and mothers. And you can view historical wristband records, these tags are unique and non-repeatable, so as to avoid the phenomenon of mistakes. For easy identification by the naked eye, the basic information of the baby can be pasted on the wristband: parent’s name, date of birth, gender, nurse’s name, etc.
2) Real-time monitoring
Mother-infant interaction: When a mother wears a button label, the mother can actively request to check the baby’s status by pressing a special label button. The monitor screen of the baby will automatically appear on the screen of the ward, showing the baby’s current location and nursing status information.
Anti-theft alarm: signal detectors are installed in the ward area, entrances and exits of the ward, and important external passages to know the location of the baby in real time. If the baby leaves the ward or ward without permission, the alarm will be activated immediately, and according to the alarm level , Can appear at the nursing workstation and security monitoring center at the same time, and send out an alarm sound to the mother’s wristband.
Anti-lock error: When the baby appears in the same area with other unbound mothers or caregivers, the system will analyze according to the preset anti-lock error logic and issue an early warning. It can be compared and confirmed through the mobile terminal.
Tag tamper-proof: The tag worn by the baby has a tamper-resistant function. If the tag is deliberately removed, the tag will immediately notify the monitoring center and sound the alarm.
Video linkage: The system monitoring platform can be linked with the hospital’s video network. When an alarm occurs, the camera in the alarm area is immediately switched to view the video image of the alarm area.
3) Baby care management
Check-in and check-out: When the baby needs to leave the ward due to bathing, emergency care, etc., it needs to sign out through the handheld terminal or on the PC console. Authorization is allowed to leave, otherwise the alarm will prompt and the time will be automatically given when returning to the ward Check-in.
Baby care records: The system matches the hand-held mobile nursing workstations for the nursing staff. During the nursing process, the nursing staff can scan the mother and baby wristbands through the mobile workstation to perform nursing operations. The system will record all bedside nursing services, through or through identification nursing Personnel tags, automatically record the inspection records of nursing staff.
4) Comprehensive query
Comprehensive query can provide detailed information of mother and baby based on wristband, mother’s name, bed number, baby’s date of birth, and provide historical record query functions such as alarm events, personalized services, and nursing records.
5) Monitoring of infant care environment
Temperature and humidity monitoring in baby-friendly areas: By installing temperature and humidity sensors, the temperature and humidity data of the ward and baby-friendly areas are collected, and displayed on the monitoring platform in real time, so as to provide a more comfortable nursing environment and bath water temperature monitoring: At present, the water temperature of the baby bathing pool and swimming pool are determined by the nursing staff’s own feelings. Different nursing staff have different experience values. To ensure that the water temperature is within a reasonable range, the system provides a water temperature tester, which is displayed on the monitoring platform after collection, for nursing care The personnel provide the basis for nursing. When the water temperature is too high or too low, the system will automatically generate an alarm.
6) Personalized service
For mothers and family members, baby wristbands have a certain commemorative value. At the same time, the baby’s photos, hand shapes and other baby characteristics can be printed on the wristband through technical means. By building this system, it can provide babies with more More personalized service.
Four, application significance
1) Improve the level of hospital informatization and intelligent management, and lay a solid foundation for the hospital to build a higher and more comprehensive informatization;
2) Prevent patients and babies from being misidentified and receiving wrong treatment;
3) Provide patients with wireless help-seeking functions to improve the level of humanized medical services;
4) Help doctors or nurses to confirm the identity of infants with similar characteristics and communication difficulties, and prevent miscarriage;
5) Monitor and track people who enter high-risk areas without permission to prevent unnecessary accidents;
6) Prevent the occurrence of malicious exchange and baby theft through measures such as tag anti-disassembly, ID number uniqueness and mother-to-child matching measures;
7) Provide hospitals with more personalized services related to newborn babies to meet the needs of family members while increasing hospital admissions
