Medical waste management system solution with RFID technology

RFID radio frequency identification technology is an emerging high-tech technology that has caused changes in the field of automatic identification after barcodes. It uses the penetrability of radio electromagnetic waves, the characteristics of long-distance transmission and high-speed data exchange to achieve identification through specific protocols. Technology for automatic identification of item information. In the identification of target objects, RFID technology has essential advantages over the currently widely used barcode technology: it can read and write wirelessly over long distances, it can read and write penetrably, and it can read and write at high speeds. , Stores more data, can be used in harsh environments, etc. Therefore, RFID technology has completely subverted the traditional management model in many automatic identification fields.

The characteristic information of the object to be identified collected through the radio frequency identification system is usually processed by intermediate software, or the collected identification information is directly processed through computer information processing technology (such as database technology, etc.) and computer network technology (Intranet & Internet) Technology) to realize information integration, sharing, long-distance transmission, etc. to directly serve business application systems.

With the goal of full-process supervision of medical waste and RFID technology as the core, we will build a new medical waste management platform based on RFID technology to supervise the entire process of collection, transfer, and destruction of medical waste and eliminate possible loopholes, which will effectively Prevent the spread of various viruses and other sources of pathogenic bacteria during the collection, transfer, and destruction of medical waste, and achieve intelligent management of the entire process of medical waste from collection and transportation to sorting, utilization, processing, and disposal. At the same time, reduce Strengthen the statistical work of waste flow management, improve the scientificity and preparedness of statistical data, further standardize and informatize medical waste management, and improve the level of supervision of medical waste.

The RFID medical waste supervision platform can fundamentally change the way of paper-based bills. In all circulation, statistical records of medical waste processing location, handover person, processing time and other data are automatically completed by the system, and the records are automatically uploaded. It avoids the interference of human factors on system data, making the data more comprehensive, accurate and reliable.

Tag binding

When the medical waste barrel is empty, it is bound to the RFID electronic tag. RFID can be bound to the barrel one by one by pasting, injection molding or rubber coating. After binding, the RFID electronic tag data can be read and the corresponding waste bin information can be located. The RFID tag completes data initialization and synchronizes the data to the system background.

4.3.2 Waste collection

For institutions with large waste volumes, it is recommended to install fixed data collection equipment and integrate it with a weighing system. The waste barrel with the electronic tag installed will be weighed together with the medical waste. When the RFID data collector reads the electronic tag information of the barrel, it obtains the weight of the medical waste from the weighing system and writes the weight information to the electronic tag. middle. The system background updates new waste information in real time.

For more dispersed institutions with a small number, mobile data collection equipment can be used. The human body can be a few meters away from the waste barrel to collect data, reducing intermediate links and reducing the risk of infection for staff.

4.3.3 In-transit monitoring

Installing a GPS/Beidou real-time positioning system on the transport vehicle, and using camera monitoring technology, can collect real-time precise location information of the vehicle, synchronize the time, and transmit the data back to the system backend in real time. Functions such as yaw reminder and real-time alarm can be set according to needs. Supporting trajectory query has a significant effect on improving transportation safety and ensuring the scheduled and scheduled transportation of medical waste.

4.3.4 Transfer stations and cleaning centers

In order to improve the storage safety of medical waste, each transfer station and each storage node can adopt the supervision method as shown below if it is necessary to conduct real-time supervision of waste. An RFID data collection system is deployed above the waste storage point to monitor the storage, entry and exit of waste barrels in the entire storage area in real time. Early warnings can be issued for any non-compliant operations. Maximize the security of supervision, real-time data storage and transparency.

For each cleaning center or areas where waste barrels circulate quickly, the following node control methods can be adopted.

Installing a fixed data collection device at the entrance of the cleaning center can control the waste barrels entering the cleaning center in real time. When the waste is cleaned and leaves the cleaning center, the system collects the information of the waste barrel again, which is marked in the background of the system. The bucket "has been cleaned". Therefore, in the next circulation link, when the system collects the bucket information, it can query in the system background whether the bucket has been cleaned, and those that do not meet the requirements will not flow into the next link to ensure the safety of the bucket.

4.3.5 Incineration center

In the incineration center, barrels containing medical waste are placed on the conveyor belt. When they arrive at the weighing position, the waste barrel tags are read by RFID. At the same time, they are weighed again and the data is sent back to the background management system. The management system will obtain The weight information is compared with the weight information stored in the electronic label of the trash can. If there is no error, the subsequent incineration operation will be carried out. Otherwise, an alarm will be issued to prompt the staff to handle it.

4.4 System benefits

The medical waste supervision platform based on RFID technology is composed of advanced RFID technology, combined with real-time positioning system, monitoring system, weight collection equipment, display system, sound and light prompt system, server, information transmission system, etc., and is in line with the existing national medical waste Management of relevant laws and regulations, under the current background of strict prevention and control of COVID-19, will significantly improve the level of supervision of medical waste and contribute to joint prevention and control:

1. Real-time, accurate and transparent tracking of the entire medical waste disposal process

Regulatory departments, health departments, and individual Hospitals and clinics can log in anytime and anywhere to check the amount of medical waste generated and processed by their unit at any time, and provide a basis for future collection and classification. The incineration center can easily understand the quantity and weight of medical waste collected and transported every day, and can efficiently make corresponding work arrangements such as transportation and incineration. All data is real-time, accurate and transparent.

2. Reduce the risk of infection and improve management efficiency

Utilizing the technical characteristics of UHF RFID, data can be collected remotely, contact-free, and automatically, reducing direct contact between personnel, reducing the risk of infection, and improving overall management efficiency.

3. Provides a public data verification platform

From collection, transportation, transfer, disposal and incineration, all links are handed over with electronic data records. Relevant regulatory agencies can trace the continuity of the data. The query system provides a fair data platform, and medical waste with objections can be traced. Fair arbitration. At the same time, regulatory authorities can track and handle abnormal situations in real time based on automatic system prompts.
