Problems solved by technology

However, these intelligent electrocardiograph calibration systems cannot be used for existing electrocardiograph calibration instruments. When the electrocardiograph is to be intelligently calibrated, the existing electrocardiograph calibration equipment must be replaced, which increases the cost of verification and causes existing Electrocardiogram machine calibrating instrument shelved waste

Abstract

The invention discloses a digital electrocardiograph calibration method and system. The digital electrocardiograph calibration method is used for intelligently calibrating a digital electrocardiograph. The digital electrocardiograph calibration method includes receiving electrocardiographic data outputted by the electrocardiograph to be calibrated by an access module, transmitting the received electrocardiographic data to an identifying module, identifying a calibration term which the received electrocardiographic data belongs to by the identifying module, judging whether the received electrocardiographic data is qualified or not by means of calibration standard by the identifying module according to the identifying results. By the digital electrocardiograph calibration method and system, intelligent calibration of the digital electrocardiograph can be realized, calibration efficiency is improved, manual error is reduced and calibration accuracy is improved. Meanwhile, the digital electrocardiograph calibration method and system is applicable to existing calibrators.

Description

technical field [0001] The invention relates to the field of measurement verification of instruments and meters, in particular to a digital electrocardiograph verification method and system suitable for existing verification instruments. Background technique [0002] An electrocardiograph is an instrument used to record the physiological electrical signals generated by the heart's activity. Due to the advantages of mature diagnostic technology, reliability, easy operation, moderate price, and no damage to patients, the electrocardiograph has become a medical electronic instrument commonly used in clinical diagnosis and scientific research. In order to ensure the accuracy and reliability of clinical diagnosis and prevent misdiagnosis caused by abnormal performance of electrocardiographs, the state includes electrocardiographs in the scope of compulsory verification measuring instruments. At present, the existing electrocardiograph calibration instrument needs to print out th...
