As we all know, compared with general domestic garbage, the biggest harm of medical waste is the secondary transmission of viruses and bacteria. The harm of virus bacteria is dozens or even hundreds of times that of urban domestic garbage. A piece of medical waste involves many links from generation to centralized disposal, and it has to go through many links such as department classification, packaging, temporary storage, in-hospital transfer, centralized storage, out-of-hospital transfer, and terminal disposal. If there is a problem in any link from the source to the disposal process, it may affect public health and the surrounding environment.

On the morning of November 12, a medical waste collector from a hospital in Wuhan stood in front of the intelligent medical waste transfer vehicle, wearing a mask to "brush his face" after turning on the machine, and with the help of the car’s electric power, he walked to a dirt room in the surgical building. . With a beep, the medical waste car sensed the location and automatically checked in. After the nurse in charge of the dirty room also "brushed his face" to identify, Old Xu began to work.

He opened the medical waste bucket in the filth room, took out a bag of infectious waste, and put it on the high-precision electronic scale that came with the medical waste transfer vehicle. The machine automatically recognized the weight and printed it out after a few seconds. On the label paper, the type, weight, bar code, department and collection time of the bag of medical waste are written. Old Xu put the label on, put the bag of medical waste into the transfer car, and set off for the next stop in the dirt room.

The daily amount of medical waste, how many kilograms, what type, which department it comes from, and how long it stays in the temporary storage area can all be monitored in real time. With the help of the intelligent system, the hospital's medical waste has basically achieved "Nissan Nissan". The traditional medical waste management model only focuses on results and lacks the management of the process. Once the loss of medical waste occurs, it is difficult to find out in time, and there is no way to trace the source of the lost medical waste, which brings a great deal to the management of medical waste. Troubles.

The medical waste traceability management system based on UHF RFID technology is a new generation of medical waste traceability mode that manages the whole process of the source of medical waste. The system is equipped with smart scales and ultra-high frequency handhelds, with a high degree of automation and easy operation for packing and handover operations. UHF RFID readers are used to automatically scan the warehouse in and out, which greatly reduces the amount of labor. The whole system realizes the whole process traceability from front-end collection of medical waste, mid-end transfer, and end-of-end storage. All data can be viewed in real time through the medical waste management system or APP, thus effectively standardizing the medical waste management process and standardizing the electronic station Account. At the same time, when the system discovers abnormal data of medical waste, it can send a dangerous warning at the first time, so as to avoid the loss of medical waste.

The use of RFID cable tie tags is equivalent to attaching an "identity card" to medical waste. According to the characteristics of RFID uniqueness, remote reading and batch reading, it can trace the circulation of medical waste, monitor the transfer route, and enter and exit the warehouse. The automatic monitoring and inventory monitoring also reduce the contact of the transfer personnel to medical waste and reduce the possibility of cross-infection.

What functions can the RFID technology medical waste traceability management system achieve?

1. Really eliminate the interference of human factors on the process

In the traditional supervision system, the medical waste transfer certificate is a paper form, which needs to be filled out manually. And this process is seriously uncontrollable. In the process of work, human intentional or unintentional negligence, omissions and other errors have made it difficult to manage and control medical waste information. Once a medical waste pollution incident occurs, it is very difficult to quickly trace the source due to the confusion of process data and find the most urgent virus control point. And management points.

2. Improve supervision capabilities and ensure safety supervision

The treatment of medical waste during the new crown pneumonia epidemic is a top priority, and every waste should be monitored. Therefore, in the source area, in addition to the standardized collection of medical waste, each barrel should be weighed and the weighing data uploaded to the system cloud platform. During disposal, the quantity of waste in each barrel is weighed and compared to maximize the safety of waste management. The use of RFID technology can realize electronic weighing, automatic data storage, and automatic upload without additional workload and no occupation time.

3. Supervision of transportation in transit

The government specifically requires the transportation and disposal of new crown pneumonia wastes, which must be determined by the route and time. Therefore, through information technology, the control of transportation routes and time can be achieved, and the full supervision of medical waste can be truly achieved.

4. Improve node management and control capabilities and eliminate human negligence

New crown pneumonia waste must be stored at designated locations and cleaned at designated locations. By setting up Honglu RFID reading and writing equipment in these areas, automatic data collection and real-time supervision can be realized for whether the waste has arrived in the area, whether it is reasonable to leave the area, and whether it stays for enough time, etc.

The RFID medical waste monitoring platform can fundamentally change the way of paper-based receipts. In all circulation, the processing location, transferee, processing time and other data statistics and records of medical waste are automatically completed by the system, automatically recorded and uploaded, and at the same time It avoids the interference of human factors on the system data, making the data more comprehensive, accurate and reliable.

The medical waste traceability management system aims at the whole-process supervision of medical waste, with RFID technology as the core, builds a new type of medical waste management platform based on RFID technology, supervises the whole process of the collection, transfer, and destruction of medical waste, and eliminates possible occurrences The loopholes can effectively prevent the spread of various viruses and other pathogenic sources of pollution during the collection, transfer, and destruction of medical waste, and realize the tracking intelligence of the whole process of medical waste from collection and transportation to sorting, utilization, treatment and disposal. Management, at the same time, reduce the intensity of waste flow management statistics, improve the scientificity and preparation of statistical data, further standardize and informatize medical waste management, and improve the level of medical waste supervision.
