Analysis of Hospital Waste Monitoring and Management System Based on RFID Technology

The issue of medical waste disposal has received public attention. The development of information technology has made it possible to establish a unified platform for the real-time supervision of medical waste. The new revolution in service and supervision methods has come from radio frequency identification (RFID) and satellite positioning technology. development of.

First, system background

After experiencing SARS in 2003 and the H1N1 outbreak in 2009, the issue of medical waste disposal has received public attention. In order to manage medical waste well, the Ministry of Health promulgated the Regulations on Medical Waste Management on June 16, 2003. 》Incorporating medical waste management into the legal system. Afterwards, the experts discussed the issue of medical waste management from multiple perspectives of IS014000 environmental management system, ethics, sociology, etc. Medical waste management is not only a difficult problem in hospital management, but also an important public health issue.

The development of information technology has made it possible to establish a unified platform for the real-time supervision of medical waste. The new revolution in service and supervision methods has come from the development of radio frequency identification technology and satellite positioning technology. With the popularization of information systems and the improvement of informatization, the information processing capabilities of hospitals and specialized waste disposal companies have greatly increased, and information management technologies such as electronic tag management of electronic waste management, electronic billing, electronic surveillance, and online monitoring have been promoted. Achieving a new leap from traditional manual processing to modern intelligent management already has a good technical foundation. High-speed, high-efficiency information network platform and EDI (Electronic Data Interchange) medical waste RFID monitoring system based on GPS technology combined with GPRS technology to realize visualized medical waste transportation management and real-time positioning will realize medical waste for environmental protection departments. The full supervision of the processing process provides basic information support and guarantees.

Fourth, system composition

The medical waste RFID monitoring system consists of eight subsystems, which are the data application platform, the visualization center of the monitoring center, the real-time tracking system for GPS collection and transportation vehicle routes, the RFID electronic lock system for the collection and transportation vehicles, and the video monitoring system. RFID check medical waste incineration system, the main operational processes medical waste electronic manifest system, collection, transportation and vehicle management system <br> <br> RFID RFID monitoring system for medical waste:

Electronic waste generated by medical wastes → Production of dispatched vehicles → Out of vehicle → Collection of medical waste (video start monitoring and collection process) → Medical waste turnover barrel weighing (weighing weight is uploaded to the system in real time, and RFID tag information is distributed) → Waste Loading (receiving and unlocking of the truck and recording the unlocking information and uploading the system in real time) → Transportation (positioning of the GPS positioning system for regular transmission of the vehicle) → Transit center (transit center's arrival and departure vehicle arrival time, collected waste allocation time) → Transportation (GPS The positioning system regularly transmits the location of the vehicle) → Incineration center (upload vehicle arrival time) → Receiving waste to be burned (starting video surveillance operation) → Entering the incineration assembly line → Entering the medical waste turnover barrel weight comparison link (information uploading incineration center monitoring room, After the process is finished, the information upload system) → the process ends.

(1) Electronic waste single system for medical waste

The electronic life cycle management of “from cradle to grave” monitors the transfer of medical waste throughout the process to ensure that medical waste is properly transported to designated locations.

Including the application of a single, scheduling arrangements, the release of the single, the transport unit to accept, accept the unit to accept.

Provide automated services to facilitate users at all levels: Automatically remind the EPA that medical waste has not arrived within a certain period of time. Overdue medical waste has not been sent for incineration, and it automatically reminds the EPA of waste transportation discrepancies and is automatically identified by the RFID vehicle management system.

Online confirmation of waste transportation, users at all levels can manage the related business on-line.

(2) Receiving Vehicle RFID Management System

It manages the life cycle of the collection and transportation vehicles and the life cycle of the mission.
