Application of RFID in Medical Disinfection

In the medical industry in recent years, 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 information (HIS) technology , to provide greater convenience for patients and hospitals. The RFID supply room equipment package traceability management system is the guarantee of effective management for the hospital disinfection supply room. The RFID radio frequency identification technology supply room equipment 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 combined with network technology. Through the use of this system, the management of the disinfection supply room is scientific and the responsibilities are clarified.

Including key technologies of industrialization and key technologies of application, among which the key technologies of RFID automatic identification industrialization mainly include: RFID tag chip design and manufacturing: such as low-cost, low-power RFID chip design and manufacturing technology, suitable for tag chips to achieve New storage technology, anti-collision algorithm and circuit implementation technology, chip security technology, and integration technology of tag chip and sensor, etc. Antenna design and manufacturing: such as RFID electronic tag antenna matching technology, RFID electronic tag antenna structure optimization technology for different application objects, multi-tag antenna optimization distribution technology, on-chip antenna technology, RFID Reader smart beam scanning antenna array technology, and RFID Electronic tag antenna design simulation software, etc.

System implementation goals:

From a management perspective:

The system realizes the strengthening of personnel management, fully mobilizes the enthusiasm of the personnel, enhances the staff's sense of responsibility, clarifies the scope of responsibility, and reduces the risk of medical accidents; this system manages, inquires, and counts the equipment packages in the disinfection supply room. , analysis, facilitates the configuration of equipment kits between hospital departments, the inspection of supervision departments, and the leadership of decision-making. The hospital safety management mechanism has been improved. There are well-documented problems, and the goal of information management of the entire process is finally achieved.

From an economic point of view:

This system achieves the cost control of equipment kits in the sterile supply room by reusing RFID electronic tags. Through the use of this system, paperless office is provided and office costs are reduced. Through the use of this system, the configuration of the instrument package is more reasonable, and repeated purchases, losses, etc. are avoided, and the goal of cost saving is finally achieved.

From the perspective of function expansion:

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

System Features：

In terms of coupling method (inductive-electromagnetic), communication process (FDX, HDX, SEQ), data transmission method from RF card to reader (load modulation, backscatter, higher harmonics) and frequency range, different There are fundamental differences in the non-contact transmission method, but all readers are similar in functional principle and the design and construction determined by them. All readers can be simplified into two basic modules of high-frequency interface and control unit.

The high-frequency interface contains a transmitter and a receiver, and its functions include:

(1) Generate high-frequency transmit power to activate the radio frequency card and provide energy; modulate the transmit signal for transmitting data to the radio frequency card; receive and demodulate the high frequency signal from the radio frequency card.

(2) The recorded information of the instrument pack is more accurate and comprehensive: each instrument pack is encapsulated with an electronic label, and the label Stores data such as the type, quantity, and sterilization date of the instrument. These data can be read throughout the process. Data such as issuance, recycling, 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 recycling, cleaning, packaging, sterilization, and distribution of instrument kits by reading electronic labels, which can be excluded in the event of infection accidents. The responsible link and the responsible person are finally determined after the non-responsible link;

(4) Avoid the hidden danger of infection recorded on the traditional instrument wrapping paper: The record on the instrument wrapping paper as a traditional recording method actually constitutes one of the sources of surgical infection. After adopting the RFID management and traceability system, the recording paper is no longer used, thereby avoiding risk of infection;

(5) Cost saving: The system records the relevant data of sterilization and disinfection, which saves a certain amount of time, and saves considerable cost because the disinfection test paper is no longer used. After the harsh environment of atmospheric pressure, the label can still work normally.
