Putting the instrument bag into a sterilization machine, selecting a sterilization program, starting sterilization of the instrument bag, and transmitting the number of the sterilization machine, the sterilization program, the number of the pots and the starting operation time to a sterilization tracing system through an interface of the sterilization machine. The sterilization tracing system automatically generates sterilization pot number information according to the sterilization starting information received by the interface; and (5) opening the sterilization pot for several times by a sterilization worker in the supply room, brushing a label of the sterilization worker, and clicking for storage. When the operation of the sterilization machine is finished, the sterilization result information such as sterilization duration, sterilization temperature/pressure and the like is transmitted to the sterilization tracing system through the interface, and the sterilization tracing system automatically inserts the information such as the sterilization duration and the like transmitted by the machine interface into the sterilization pot number information automatically generated when the operation is started according to the sterilization finishing information received by the interface.

(7) And (3) sterilization monitoring: after sterilization, the sterilization tracing system identifies the RFID label of the sterile instrument package in the sterilization monitoring area through the RFID reader-writer, reads related sterilization information, takes out the instrument package after sterilization to the monitoring area by monitoring personnel, performs chemical monitoring and biological monitoring, brushes a monitoring result and a monitoring person label on a system sterilization monitoring interface after monitoring is completed, and clicks for storage.

When the system is used, an interface is used for scanning the hospital number of a patient, the label of an operator and the label of an instrument package so as to facilitate tracing.

However, the existing RFID disinfection tracing management system has the following defects:

1. in the cleaning, disinfecting and sterilizing link of the instrument package, the cleaning, disinfecting and sterilizing time read by the system is derived from the time of cleaning, disinfecting and sterilizing a machine and a high-temperature pressure steam sterilizer from the beginning to the end of operation, but not the time of the sterilized instrument package staying in the machine, so that the real instrument package is in the machine in the cleaning, disinfecting and sterilizing time recorded on the disinfection tracing system, and the authenticity of the tracing data recorded by the system cannot be guaranteed.

2. In the cleaning, disinfecting and sterilizing links, the information of the instrument packages which correspond to the number of pans needs to be added by scanning through an inventory machine or manually inputting the bar code labels on the instrument packages, and the automation degree needs to be improved.

3. Paste a packet outer label in packing/nuclear packet stage, if the apparatus package is changed the sterilization before the pot is gone into in the sterilization and is set for, then need print again, paste a packet outer label sterilization information, not only increase the manual work volume, also lead to the waste of consumptive material.
