System introduction

In recent years, in the medical industry, with the construction of hospital informatization and intelligent management and the continuous improvement of patients’ satisfaction with medical services, the continuous combination and improvement of hospital radio frequency identification (RFID) and hospital informatization (his) technology provide greater convenience for patients and hospitals. RFID supply room instrument package traceability management system is the guarantee to provide effective management for hospital disinfection supply room. RFID RFID technology supply room instrument package traceability management system is developed according to the current situation of hospital disinfection supply room management and its importance in the medical process. The system uses radio frequency identification (RFID), bar code technology and network technology. Through the use of this system, the management of disinfection supply room is scientific and the responsibility is clear.

It includes two aspects: industrialization key technologies and application key technologies. The key technologies of RFID automatic identification industrialization mainly include: RFID tag chip design and manufacturing: for example, low-cost and low-power RFID chip design and manufacturing technology, new storage technology suitable for tag chip implementation, anti-collision algorithm and circuit implementation technology, chip security technology, And the integration technology of label chip and sensor. Antenna design and manufacturing: for example, RFID tag antenna matching technology, RFID tag antenna structure optimization technology for different application objects, multi tag antenna optimization distribution technology, on-chip antenna technology, RFID reader / writer smart beam scanning antenna array technology, RFID tag antenna design simulation software, etc.

System implementation objectives

From the perspective of management:

The system can strengthen personnel management, fully mobilize personnel’s work enthusiasm, enhance staff’s sense of responsibility, clarify the scope of responsibility, and reduce the risk of medical accidents; Through the management, query, statistics and analysis of instrument kits in the disinfection supply room, the system facilitates the allocation of instrument kits between hospital departments, the verification of supervision departments and the decision-making of leaders. The hospital safety management mechanism has been improved. The problems are well documented, and finally achieve the goal of information management of the whole process.


The system can control the cost of instrument package in disinfection supply room by reusing RFID electronic tags. Through the use of this system, paperless office is provided and the office cost is reduced. Through the use of this system, the configuration of instrument package is more reasonable, avoiding repeated purchase and loss, and finally achieving the goal of cost saving.

In terms of function expansion:

The system provides the interface with his and other large-scale systems to realize the system data sharing of the whole hospital. Ensure software expansibility and reserve interfaces with other monitoring systems.

Software environment:

Application of radio frequency identification technology in instrument kit of disinfection supply room in hospital

System characteristics

In terms of coupling mode (inductance electromagnetic), communication flow (FDX, HDX, SEQ), data transmission method from RF card to reader (load modulation, backscatter, high-order harmonic) and frequency range, different non-contact transmission methods are fundamentally different, but all readers are very similar in functional principle and design structure, All readers can be simplified into two basic modules: high frequency interface and control unit.

The high frequency interface includes transmitter and receiver, and its functions include:

(1) Generating high-frequency transmission power to start the RF card and provide energy; Modulating the transmission signal for transmitting data to the RF card; Receive and demodulate the high-frequency signal from the RF card.

(2) The recorded information of the instrument package is more accurate and comprehensive: each instrument package is encapsulated with an electronic label, which contains data such as instrument type, quantity and disinfection date. These data can be read in the whole process, and data such as distribution, recovery and cleaning can be supplemented at any time;

(3) Improve management efficiency and facilitate traceability: relevant managers can easily understand the information of each link in the whole process of instrument package recovery, cleaning, packaging, sterilization and distribution by reading the electronic label. In case of infection accident, the irresponsible link can be eliminated and the responsible link and person can be finally determined;

(4) The hidden danger of infection recorded on the traditional instrument package paper is avoided: as a traditional recording means, the recording on the instrument package paper actually constitutes one of the sources of surgical infection. The recording paper is no longer used after the RFID Management and traceability system is adopted, so as to avoid the hidden danger of infection;

(5) Cost saving: by systematically recording the relevant data of sterilization and disinfection, a certain time is saved, and considerable cost is saved because the disinfection test paper is no longer used. High temperature resistant electronic label is adopted: after the harsh environment of 143 ℃ high temperature and 3 atmospheres, the label can still work normally.
