Medical waste management based on RFID technology

The disposal process of medical waste needs to be controlled and managed from the source. Its collection, storage, transportation, and processing must be supervised throughout the process, especially for the disposal of highly contagious medical waste such as COVID-19. During the whole process of control, the supervision of medical waste cannot be missing, but the less The more people involved, the more the risk of infection can be minimized.

With RFID technology as the core, build a new medical waste management platform based on RFID technology, supervise the whole process of medical waste collection, transfer, and destruction, eliminate possible loopholes, further standardize and informatize medical waste management, and improve medical waste management. Regulatory level of medical waste.

RFID Medical Waste Management Process

01. RFID tag binding

As the carrier of data, the RFID electronic tag realizes the conversion of physical flow to data flow through binding with waste barrels, and provides basic data for this system. When the medical waste barrels are vacant, the RFID tags can be bound to the barrels one by one by sticking, injection molding, or encapsulation. After binding, the RFID electronic tag data can be read, and the corresponding waste bin information can be located. The RFID tag completes the initialization of the data and synchronizes the data to the system background.

02. Data collection

For institutions with a large amount of waste, it is recommended to install a fixed RFID reader and combine it with a weighing system. The waste bin with the RFID tag installed will be weighed together with the medical waste. When the RFID data collector reads the electronic label information of the waste bin, it will obtain the weight of the medical waste from the weighing system and write the weight information into In the electronic label, the system background updates the new waste information in real time.

For scattered institutions with a small number, RFID handheld terminals can be used to collect data at a distance of several meters from the waste barrel, reducing intermediate links and reducing the risk of staff being infected.

03. Transportation management

Location-based services mainly use the binding of GPS devices to transportation vehicles to complete the supervision and control of the travel routes and time of transportation vehicles. Supporting trajectory query has a significant effect on improving transportation safety and ensuring the scheduled and timed transportation of medical waste.

04. Transshipment and Incineration

In the transfer center and incineration center, the barrels containing medical waste are placed on the conveyor belt. When they reach the weighing position, the label of the waste barrel is read by the RFID reader, and at the same time, it will be weighed again and the data will be sent back to the background management system. , the management system will compare the obtained weight information with the weight information stored in the electronic label of the trash can. If there is no error, the subsequent transfer and incineration operations will be carried out. Otherwise, an alarm will be issued and the staff will be prompted to deal with it.

RFID Medical Waste Management Advantages

1. Realize the traceable management of the collection, transportation and centralized disposal of medical waste barrels;

2. Reduce the contact between personnel and medical waste and improve the efficiency of medical waste disposal;

3. It can operate in batches, intelligently identify and automatically enter and leave the warehouse, and synchronize with the background data in real time;

4. Prevent medical waste from being used by criminals, causing pollution to the society and endangering people's health;

5. Statistical reports have various forms and complete information, which can be exported and printed for easy management and query;

6. The RFID handheld terminal has a long identification distance and a long battery life, which improves the efficiency of medical waste collection;

7. The RFID reader can be connected with multiple antennas, which can be identified in batches from all directions and multiple angles without missing reading.
