RFID (radiofrequency identification) technology is radio frequency identification, also called electronic tag, radio frequency identification, is a non-contact automatic identification technology, it automatically recognizes the target object and reads and writes related data through radio frequency signals, so there is no need for identification systems and identification Establish mechanical or optical contact between targets. RFID technology is one of the core technologies of the perception layer of the Internet of Things. As an emerging automatic identification technology, it has been widely used in many fields such as logistics, transportation, and medical treatment.
In recent years, hospital informatization construction has developed rapidly, but most of the informatization construction in operating rooms is still station-type work or stand-alone operation in the operating room. How to use the Internet of Things technology and mobile smart terminals to improve the informatization construction of the operating room is still to be developed Or the primary research and development stage. According to the operating room management specifications, our hospital combines manual work procedures and content, on the basis of HIS and surgical anesthesia management system, adopts RFID technology, and establishes an intelligent operating room management system through mobile smart terminals to improve the standardization and digitalization of operating rooms , Intelligent management level.
Design Principles of Intelligent Operating Room Management System
System architecture design
The server side of this system uses .NET as the system development platform, the database uses Microsift SQL Server 2008, and the mobile smart terminal uses Android development technology. Through the Wifi wireless network, it exchanges data with the server side. The server side is unified with third-party vendor systems, including HIS And surgical anesthesia management system. After powering on, the nurse directly scans the RFID badge card worn in the surgical gown through the surgical gown, and then logs in and enters the functional interface of the mobile smart terminal.
Main functions of the system
The system consists of five functional modules, including surgical patient safety check, blood safety management, high-value consumables management, surgical specimen delivery management, and operating room equipment management. Each functional module is designed based on surgical procedures and work content, combined with RFID technology and mobile smart terminals. On the basis of meeting regulatory requirements, it subverts the traditional work model, innovates user experience, realizes intelligent management, and significantly improves work efficiency and work quality.
Application Practice of Intelligent Operating Room Management System
Surgical patient safety check
Through the RFID tag management of the operating room, surgical patients wear RFID wristbands, and medical staff (including surgeons, anesthesiologists, and surgical nurses) uniformly wear RFID badges. Before surgery, surgical nurses use mobile smart terminals to scan patient wristbands. The system Automatically display the patient’s surgery-related information, and then scan the RFID tags of the operating room one by one, the RFID badges of the surgeon, anesthesiologist, and surgical nurse, connect to the surgical scheduling system, and intelligently check it. If the verification is wrong, it will be reminded by sound, vibration, and eye-catching on-screen display.
If the medical staff forget to wear the badge, the system also supports entering the account number and password to identify the medical staff.
Blood safety management
Manage the use of RFID tags for blood bags and wear RFID wristbands to patients. Before giving blood to the patient, the surgical nurse uses a mobile smart terminal to scan the patient’s wristband and RFID tag on the blood bag, and the system automatically performs matching and identification. If it does not match, it will be reminded by sound, vibration, and eye-catching screen display. At the same time, if the blood bag exceeds the expiration date, a corresponding warning will be issued.
High-value consumables management
Using RFID tags, the whole life cycle of high-value consumables in the hospital (that is, from the purchase and storage of RFID tags to the final use on patients) is refined management, and the whole life cycle can be traced.
When purchasing high-value consumables, the medical engineering department uses RFID tags for storage management. The surgical nurse scans the patient’s RFID wristbands and RFID tags of high-value consumables through smart mobile terminals to automatically record the use of high-value consumables. Through the docking with the high-value consumables management system, the medical engineering department can understand the use of high-value consumables in real time. By connecting with the HIS charging system, automatic billing can improve work efficiency and avoid the risk of missed expenses, so as to achieve full control of high-value consumables. Traceable management of life cycle. In addition, it also supports the management of the expiry date of high-value consumables. Overdue consumables are automatically reminded when they are used to avoid medical accidents.
Surgical specimen submission management
Using RFID tags, the surgical specimens are collected from the patient and sent to the pathology department for the whole process of tracking and tracing management. The procedure of the surgical specimen submission process is divided into four steps: specimen registration, specimen packaging, specimen verification, and specimen reception. In each step, a corresponding person uses a mobile smart terminal to check and confirm the information and status of the surgical specimen in real time. The multi-tag identification capability of RFID tags can perform batch identification of multiple surgical specimens and intelligent batch transfer. In addition, it also supports the addition of multimedia records such as images and audio to the management of surgical specimens, and the pathology report of the specimens can be obtained online. At the same time, the system can automatically generate a pathology application form, and automatically capture most of the content on the application form, standardize the filling of the application form, save manual writing time, and improve work efficiency.
Operating room equipment management
Using RFID tags, each equipment in the operating room is uniquely identified. Through the information system, the information and status of each equipment can be accurately managed. Through the mobile intelligent terminal, various management of equipment can be carried out in real time, including inventory, maintenance, scrapping, transfer, etc., which greatly reduces the difficulty of equipment management, and provides real first-hand data to provide data support for hospital accounting. In addition, device management also supports multimedia recording of images, audio, etc., to avoid ambiguity and significantly improve work efficiency.
Application effect of intelligent operating room management system
At present, the country is striving to build the most basic patient safety guarantee system, and the key point of the extremely risky surgical operation room safety guarantee, with the help of the Internet of Things technology, the operation room information construction can provide favorable conditions for medical care norms and safety guarantee. The intelligent operating room management system, through the targeted design of the error-prone and low-efficiency stages in the operation, uses the Internet of Things technology and mobile smart terminals to carry out standardized management to avoid medical accidents and improve work efficiency.
Surgical patient safety verification function, using RFID tags, wristbands, badges to identify objects at the same time, and the ability to recognize multiple targets at the same time, with the help of mobile smart terminals and Wifi wireless network, the safety verification of surgical patients can be quickly and intelligently realized.
Through the blood safety management, the probability of mistakes is greatly reduced, the patient’s blood safety is ensured, and it can be traced; through the management of high-value consumables, the management efficiency is improved, the omissions are avoided, and the medical accidents are reduced. The incidence rate of the surgical specimens has improved the quality of medical safety; through the management of surgical specimen submissions, the mobile management of surgical specimen submissions has been realized, which is convenient, fast, safe and accurate; through the management of the operating room equipment, it can assist the operating room personnel in the management The equipment is managed in a standardized manner to reduce the work pressure of the staff and improve work efficiency.
The main problems and countermeasures faced by the intelligent operating room management system
The application of the intelligent operating room management system has improved work efficiency, but there are still some problems found in the use. For example, some high-value consumables may be sent directly to the operating room by the distributor, skipping the process of sticking RFID tags, resulting in the subsequent failure of real-time management.
In response to such problems, on the one hand, the process of using consumables is standardized, and on the other hand, the online material supply management platform is considered. After the supplier logs on to the platform, they can directly print barcodes or paste RFID labels for easy management.
