1. System overview
This system uses radio frequency identification technology (ie RFID technology) to solve the current lack of visualization, informatization, and traceability management of traditional hospital bed processing procedures. The purpose of applying radio frequency identification technology to the bed treatment process is to establish a complete, flexible and real-time bed treatment traceability system.
The system will equip each hospital bed unit with an RFID tag, which is responsible for collecting and storing the attribute information of each link of the hospital bed processing process, including the bed number, the ward used, the operator number, the disinfection date, the confirmation time, and so on. The system can display the temperature, pressure and time curve of each bed unit in the disinfection process in real time, check the storage location of the existing bed unit at any time, count and analyze the usage of the bed unit, and learn the relevant information of the bed unit, including the process Relevant personnel in all links have clarified their responsibilities.
2. Overview of system operation
Task: Responsible for centralized disinfection of hospital beds after ward use and information management of the ward use process.
Purpose: Provide patients with clean, safe and comfortable bed units, effectively control hospital infections, reduce the labor intensity of clinical nurses, enable nurses to better serve patients, clarify the persons responsible for medical accidents, and provide legal basis for medical accidents.
Equipment: RFID reader, RFID tag, RFID employee card, large double door disinfection sterilizer, large double door disinfection cleaner, etc.
Environment: Located on the fifth floor of the tumor building of the Chinese People’s Liberation Army General Hospital, with a construction area of 350 square meters, it is connected to the ward. The large-scale double-door equipment serves as an isolation barrier and is divided into a polluted area, a clean area, and a work area. There is a dedicated cleaning elevator.
Disinfection method: damp heat disinfection cleaning and pressure steam disinfection
3. Disinfection mode of hospital bed units
Sterilizer: select according to the tolerance of the bed items
105°C for 5 minutes,
Keep at 80℃ for 10 minutes,
Keep at 75°C for 20 minutes.
Washer-disinfector: A0 = 600: Hold at 90°C for 1 minute, and hold at 80°C for 10 minutes.

7. System operation process
1) Registration of new hospital beds
When a new hospital bed unit is added in the hospital bed disinfection supply room, the label shall be bound to the hospital bed unit, and the hospital bed unit shall be registered in the hospital bed unit registration system. The system will automatically record the time of registration and the model of the bed unit. After the hospital bed unit is successfully registered, the RFID information management of the hospital bed unit can be carried out.
2) Distributed in sterile room
According to the confirmed ward application form, the management nurse of the supply room bed unit logs in to the bed unit issuance system with her own badge and enters the working state. The hospital bed unit passes through a dedicated channel. The RFID reader set in the channel will read the information of the hospital bed unit, and the system automatically records the information of the ward application form, the time of going out, the dispatched personnel, and whether the bed unit is within the validity period.
Before leaving get off work, the management nurse of the supply room bed unit can inquire about the number of beds used in each ward, and check the number of stock bed units in the sterile room.

3) Recycling in the ward
Supply room hospital bed unit recovery nurses can log in to the hand-held bed unit recovery system with their cards when they go to work. When hospital bed unit recovery nurses come to the corresponding department, they can first swipe the card of the staff in charge of handover in the ward to confirm their information, and after the information is confirmed, swipe them The label of the recovered hospital bed unit. The system automatically records the information of hospital bed unit recovery personnel and ward personnel, ward name, bed number, time and other information.
The hospital bed unit management nurse in the supply room can query the total number of recovered hospital bed units.
4) Operation room for storing infected area

5) Sterilization test of sterile room
After disinfection of the bed unit is completed, the bed unit disinfection nurse can log in to the hospital bed unit disinfection management system of the handheld with the card and scan the label of the bed unit. The system will verify whether the disinfection in the disinfection pot is qualified according to the disinfection process data of the disinfection pot. The system automatically records the disinfection verification personnel of the hospital bed unit, verification time and other information.
After the information verification is completed. The data is uploaded to the server for historical query.
After disinfection and verification of the hospital bed unit is completed, store it in the sterile room.

10. System technical background
The RFID (Radio Frequency Identification) used in the system is also called electronic label technology, which is a non-contact automatic identification technology. A typical RFID system consists of electronic tags, antennas, readers, application interfaces or middleware software, and transmission networks. , Business application and management system, etc. The electronic tag attached to the object is equivalent to an ID card and records the object information. The reader has the ability to read and write information to the RFID tag. Application interface or middleware software completes the collection of RFID tag data information. The transmission network realizes the transmission of data. According to the functional requirements of the reader terminal, a variety of transmission methods can be used, such as Ethernet, WLAN, CDMA, etc. The business application and management system realizes the orderly management of RFID markers, which is equivalent to the file management of objects.
