RFID technology helps hospitals build a safety barrier for medical waste

As we all know, compared with general domestic waste, the greatest 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 waste. There are many links involved in a piece of medical waste from production to centralized disposal. 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, Lao Xu, a medical waste collector from a hospital in Wuhan, stood in front of the intelligent medical waste transfer vehicle, wearing a mask and "swiping his face". . With a beep, the medical waste car sensed the location and automatically clocked in. The nurse in charge of the filthy room also "swiped his face" to identify, and Lao Xu started to work.

He opened the medical waste bin in the waste 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. Label paper, on which the type, weight, barcode, department and collection time of the bag of medical waste are clearly written. Lao Xu put the label on it, put the bag of medical waste into the transfer vehicle, and set off to the next stop, the waste room.

The amount of medical waste per day, how many kilograms, what type, which departments it comes from, and how long it has been staying in the temporary storage can all be monitored in real time. With the help of the intelligent system, the hospital's medical waste has basically been "daily produced and cleared". The traditional medical waste management model only focuses on the 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 great challenges to the management of medical waste. troubled.

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 generation. The system is equipped with smart scales and ultra-high-frequency handheld devices, and the operations of packaging and handover are highly automated and easy to operate. Inbound and outbound are automatically scanned by UHF RFID Readers, which greatly reduces the amount of labor. The whole system realizes the traceability of the whole process from the front-end collection of medical waste, terminal transfer, and terminal 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 ledger of medical waste . At the same time, when the system finds abnormal medical waste data, it can send a danger warning at the first time, so as to avoid the loss of medical waste.

The use of RFID cable tie labels is equivalent to affixing an "ID Card" to medical waste. According to the characteristics of RFID uniqueness, long-distance reading and batch reading, medical waste can be traced, transferred, route monitored, and Stored. Automatic monitoring and inventory monitoring, while also reducing the contact of transfer personnel with medical waste, reducing 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 handover certificate of medical waste 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 caused difficulties in the management and control of medical waste information. Once a medical waste pollution incident occurs, due to the confusion of process data, it is also very difficult to quickly trace the source and find the most urgent virus control point. and management points.

2. Improve supervision ability and ensure safety supervision

The treatment of medical waste during the COVID-19 epidemic is a top priority, and every waste should be supervised. Therefore, in the source area, in addition to the standardized collection of medical waste, each barrel should also be weighed, and the weighing data should be uploaded to the cloud platform of the system. During disposal, the quantity of each barrel of waste is weighed and compared to maximize the safety of waste management. Utilizing RFID technology, electronic weighing, automatic data storage, and automatic upload can be realized without additional workload or occupation of operating time.

3. In-transit supervision

The government has put forward special requirements for the transportation and disposal of COVID-19 waste, which must be determined by a certain route and at a certain time. Therefore, through information technology, the control of the transportation route and time can be realized, and the whole process of medical waste can be truly supervised.

4. Improve node management and control capabilities to prevent human negligence errors

COVID-19 waste must be stored 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 on whether the waste has arrived in the area, whether it is reasonable to leave the area, and whether it has stayed for enough time.

The RFID medical waste supervision platform can fundamentally change the way of paper forms. In all circulation, the statistical records of medical waste processing location, handover person, processing time and other data 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 to supervise the whole process of medical waste, takes RFID technology as the core, builds a new medical waste management platform based on RFID technology, and supervises the collection, transfer and destruction of medical waste throughout the process to prevent possible accidents. The loopholes will effectively prevent the contamination of various viruses and other pathogenic bacteria sources during the collection, transfer, and destruction of medical waste, and realize the intelligent tracking 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 readiness of statistical data, further standardize and informatize medical waste management, and improve the supervision level of medical waste
