Specifically, a first difference module 24 is set in the management node 2, after correction coefficients have a corresponding relationship with the medical instrument and the model of the detection item, the correction module processes to obtain correction coefficients corresponding to all instrument parameters in the instrument parameter set, the first difference module 24 corrects the instrument parameters according to the correction coefficients to obtain corrected instrument parameters, the instrument parameters in the instrument parameter set at this time have uniform numerical standards, a plurality of difference sections are preset in the first difference module 24, an average value in the instrument parameter set at this time is calculated, the average value is calculated to obtain differences with each instrument parameter, the difference sections corresponding to the different differences are different, the calculated differences are compared with the difference sections, and a first judgment result of the difference section corresponding to the instrument parameters can be obtained, if the difference section level is too high in the first judgment result, the instrument parameters of the medical instrument are indicated to have serious deviation, the first judgment result is sent to the detection node 1, workers who detect the medical instrument can be warned at the detection node 1, after receiving the first judgment result, namely, the workers can carry out the detection on the detection node 1, namely, the error can be continuously analyzed when the detection node 1 is not detected, and the error is not influenced, that the error is caused by the error is continuously detected, and the error is avoided.
Further, the risk level and the risk prompt information rule are set in the first difference module 24, and comprehensive analysis of performances of different medical instruments and equipment can be performed through data sharing at the management node.
In a preferred embodiment of the invention, the types of instrument parameters include:
The instrument production parameters are used for recording instrument parameters obtained by the detection node 1 of the first node type in the production process of detecting the medical instrument;
the instrument detection parameters are used for recording instrument parameters of the detection node 1 of the second node type, which are obtained in the laboratory detection process of the detection medical instrument.
Specifically, the medical instruments may include various instruments for detecting patient specimens, medical detection items for holding patient injection and ingestion, and the like, where, for the medical instruments for producing the detection items, the detection node 1 may detect instrument production parameters and instrument detection parameters for obtaining the medical instruments for judging performance conditions of the medical instruments.
Further, the detecting node 1 of the first node type obtains the instrument production parameter in the process of detecting the medical instrument, the detecting node 1 of the second node type obtains the instrument detection parameter in the process of detecting the medical instrument in a laboratory, and furthermore, the quality control product can be obtained in the process of detecting the medical instrument, and the performance parameter obtained by the medical instrument in production work and the actual parameter of the quality control product are compared and analyzed, so that the instrument production parameter and the instrument detection parameter of the medical instrument are obtained.
In a preferred embodiment of the present invention, as shown in fig. 4, the management node 2 further includes a second difference module 25, where the second difference module 25 is respectively connected to the correction module and the first difference module 24, and is configured to correct the instrument production parameter and the instrument detection parameter by using the correction coefficient to obtain the corrected instrument production parameter and the corrected instrument detection parameter, calculate a first difference between the instrument production parameter and the average value and a second difference between the instrument detection parameter and the average value according to an average value of the instrument parameters, determine the first difference and the second difference to obtain a second determination result, and output the second determination result to the detection node 1.

Specifically, in order to ensure that the medical instrument performance quality management system can realize data confidentiality of the detected instrument parameters and the judged result obtained by judgment while carrying out full-flow real-time monitoring on the medical instrument, the detection node 1 sends the encrypted instrument parameters to the management node 2 through the encryption key of the encryption scheme, the management node 2 decrypts the instrument parameters through the decryption key of the encryption scheme and judges to obtain a correction coefficient, and then the correction coefficient is sent to the detection node 1 through encryption.
Further, in consideration of encryption and decryption between the detection node 1 and the management node 2, symmetric encryption is selected as the encryption scheme herein.
