Monitoring Medical Waste with RFID Technology
Medical garbage is badly handled and harmful
Medical waste belongs to hazardous waste, which contains a large number of harmful pathogens, toxic and harmful chemical pollutants, radioactive pollutants and other harmful substances, so it has great danger. China has already listed it as the number one hazardous waste. In view of medical waste, the Ministry of Health has clearly stipulated that medical waste in hospitals must be stored in closed storage, fixed-point storage, and transported by personnel. Medical waste must be incinerated to ensure sterilization and avoid environmental pollution, and no form of recycling and reuse is allowed. Medical waste disposal and medical, urban construction, environmental protection, scientific research and other departments need to strengthen cooperation and supervision in all aspects.
The high-speed and high-efficiency information network platform and EDI based on the combination of RFID technology with GPS technology and GPRS technology to realize the visualization of medical waste transportation management and real-time positioning will provide basic information support for the environmental protection department to realize the whole process supervision of medical waste disposal. Guarantee.
Medical waste RFID tracking and processing system realizes the whole supervision of medical waste, improves the information management ability of medical waste, and maximizes the protection of people's life, health and safety. The design objectives of the system are:
Effectively eliminate the illegal loss of medical waste;
The process of collecting, transporting and destroying medical waste is controlled electronically by using RFID tags.
The various data of medical waste are collected and analyzed, and various accurate data are obtained.
The data collected in real time are analyzed and the dangerous time alarm mechanism is implemented.
Every medical department produces a large number of medical hazardous wastes every day. From the medical unit, the wastes are packed and transported to the transit station for weighing, and then to the medical waste incineration center by the transit station vehicles, which can be completed within 24 hours. In the whole process, the supervisory department monitors the complete disposal of medical wastes to ensure that the medical hazardous wastes discarded by medical units are disposed of without omission or that there is no possibility of reuse. At present, waste products are packed in boxes by medical units, weighed in batches (multiple boxes) after vehicles are transported to transfer stations, and then served by vehicles to the incineration Center for weighing and post-processing. Packing without sealing, weighing without subdividing into boxes, using traditional paper documents, no computer application system support management, delayed supervision.
The basic requirements of the system are as follows:
Set up medical waste RFID tracking and processing system, incineration center subsystem and supervision subsystem;
Install electronic labels on medical waste boxes. When using the waste boxes, information such as weight, unit, time and medical enterprises affiliated to the boxes are written into the electronic labels attached to the boxes.
Portable equipment and portable electronic scales are used to write the weight and the information of the medical unit to the tag attached to the box when the medical unit takes the waste. Fixed or portable reader is installed in the incineration center. The function of reading and writing the electronic tag automatically and remotely, and the alarm is given to the medical waste box whose weight does not match.
The main work of the medical waste RFID monitoring system is as follows: firstly, before the medical waste is transported out, the medical industry units first declare online, and write the relevant information such as the declared data into the RFID tag, paste it on the medical waste packaging; secondly, after the waste arrives at the centralized treatment plant, the RFID reader reads and writes the RFID tag attached to the garbage packaging. Data information, and the information of medical waste will be transmitted to the relevant regulatory authorities; finally, the waste disposal department will prescribe the right medicine, according to the corresponding disposal methods of waste categories.
The operation process of medical waste RFID monitoring system is as follows:
1) Generation of Medical Waste Electronic Joint List
2) Delivery Task Sheet Generation
3) Departure
4) Collection of medical waste (video start monitoring the collection process)
5) Medical garbage turnover bin weighing (weighing weight is uploaded to the system in real time, and RFID tag information is distributed at the same time)
6) Garbage Loading Truck (receiving truck unlocking records unlocking information and real-time uploading system)
7) Transportation (GPS positioning system timing transmission vehicle location)
8) Transfer Center (arrival time of uploading and receiving vehicles and allocation time of garbage collected)
9) Transportation (GPS positioning system timing transmission vehicle location)
10) Incineration Center (Upload Vehicle Arrival Time)
11) Receiving garbage for incineration (start video surveillance operation)
12) Enter the incineration line
13) Enter the weight comparison link of medical waste turnover bin (information upload and incineration center monitoring room, processing end, information upload system)
14) Process closure
Automatic data acquisition: realizes the weighing of medical garbage turnover bins and automatic identification and distribution of labels, and real-time data upload to the monitoring center.
Convenience: The system is fully electronic data centralized management, which makes a large number of data search work completed by the server, saves a lot of manpower, improves efficiency, and speeds up the response to events.
Data security: The system uses RFID tags designed for different occasions, which have fast identification response time and low average failure rate, ensuring the security, timeliness and stability of identification process; in addition, it uses high performance and fault-tolerant system servers to ensure the high stability, security and stability of servers. The transmission speed of the network can realize the real-time transmission of the system and ensure the timeliness of the information.
Improve the management level: centralized management, distributed control; standardize the supervision and management of medical waste collection and transportation links, supervision of all necessary links, so that emergencies can reach the top management at the first time, so that events can be handled in a timely manner.
Expansibility of the system: Considering the future development trend and information technology in the whole hazardous waste management
