Description

Technical Field

[0001] The present invention belongs to the technical field of medical instrument detection, and particularly relates to a calibration device and method for an electrocardiogram diagnosis and analysis system. Background Art

[0002] An electrocardiogram diagnosis and analysis system is an instrument used to record the physiological electrical signals generated during heart activities. Due to its advantages such as mature, reliable, simple to operate, moderate in price, and non-invasive to patients, the electrocardiogram diagnosis and analysis system has become a commonly used medical electronic instrument in clinical diagnosis and scientific research. To ensure the accurate and reliable clinical diagnosis and prevent misdiagnosis caused by the malfunction of the electrocardiogram diagnosis and analysis system, the state has included the electrocardiogram diagnosis and analysis system in the category of compulsory verification measuring instruments.

[0003] Currently, the existing calibrators for electrocardiogram diagnosis and analysis systems need to print out the corresponding waveforms item by item through the electrocardiogram diagnosis and analysis system, and then the calibration personnel measure and compare them item by item manually. This results in a large workload (eye strain, cervical and shoulder syndrome, lumbar disc herniation), low calibration efficiency, and is prone to human errors. In addition, with the introduction of the policy of exempting calibration fees for national compulsory verification and the rapid development of the medical industry, the quantity of electrocardiogram diagnosis and analysis systems to be calibrated has shown a rapid upward trend, doubling the pressure on front-line calibration personnel. The contradiction among the front-line time calibration tasks, calibration quality, and calibration personnel allocation has become increasingly prominent. To solve the above problems, it is urgent to explore and develop an automatic calibration device for electrocardiogram diagnosis and analysis systems.

[0004] However, the calibration items in the existing calibration methods for electrocardiogram diagnosis and analysis systems all output fixed waveforms, and the electrocardiogram diagnosis and analysis system itself has the attribute of loading an intelligent system, which gives illegal manufacturers the opportunity to cheat in the automatic calibration of electrocardiogram diagnosis and analysis systems. Therefore, it is necessary to develop an automatic calibration device / system with an anti-cheating function. Summary of the Invention

[0047] Referring to Figure 1 as shown, the present invention provides a verification device for an electrocardiogram diagnosis and analysis system, including: a central processing module, a power module, a human-computer communication module, a calibration module, a weak signal module, and a communication module;

[0049] The central processing module includes: a first controller, a first anti-cheating algorithm module, a first image data analysis module and a power management module; the first controller, which is respectively connected to the weak signal module and the communication module, is used to transmit the signals sent by the central processing module to an external electrocardiogram diagnostic analysis system and receive the ready signal, waveform data signal and relevant information of the electrocardiogram diagnostic analysis system generated by the electrocardiogram diagnostic analysis system; the first anti-cheating algorithm module, which is connected to the first controller, is used to perform anti-cheating algorithm analysis on the waveform data signal to obtain a conclusion on whether there is a cheating behavior; the first image data analysis module, which is connected to the first controller, is used to perform image data analysis on the waveform data signal; the power management module, which is connected to the power supply module, is used to perform intelligent charge and discharge management on the power supply module.

[0050] The power supply module includes: a power supply high-voltage module and a power supply low-voltage module; the power supply high-voltage module is used to generate a power supply; the power supply low-voltage module is used to generate a reference voltage; both the power supply high-voltage module and the power supply low-voltage module are connected to the power supply module.

[0051] The intelligent terminal device includes: a second controller, a second anti-cheating algorithm module, and a second image data analysis module; the second controller is connected to the electrocardiogram diagnosis and analysis system through the communication module, and is used to transmit the control signal sent by the intelligent terminal device to the externally connected electrocardiogram diagnosis and analysis system, and receive the ready signal, waveform data signal and electrocardiogram diagnosis and analysis system-related information generated by the electrocardiogram diagnosis and analysis system; the second anti-cheating algorithm module is connected to the second controller, and is used to perform anti-cheating algorithm analysis on the waveform data signal to obtain a conclusion on whether there is a cheating behavior; the second image data analysis module is connected to the second controller, and is used to analyze and process the waveform data signal.

[0052] An image acquisition module is also connected between the intelligent terminal device and the electrocardiogram diagnosis and analysis system, and is used to convert the waveform data signal of the electrocardiogram diagnosis and analysis system into image data for the second image data analysis module, and the second image data analysis module analyzes and processes the image data. The image acquisition module is installed in an image acquisition instrument, and the image acquisition instrument can be embedded in the intelligent terminal device for use or externally connected to the intelligent terminal device separately for cooperative use.

[0053] The present invention also proposes a calibration method for an electrocardiogram diagnosis and analysis system, which specifically includes the following steps:

[0054] Before leaving the factory or after maintenance, the calibration module detects necessary analog signals to provide a calibration basis for generating high-precision weak analog signals and meets the accuracy requirements.

[0055] S1. First, the power supply module and the power management module provide the required power supply and reference voltage for the entire calibration process, then turn on the machine, and the user inputs command signals through the human-computer communication module to set the configuration parameters of the electrocardiogram diagnosis and analysis system calibration device and the intelligent terminal device; then, select to enter the automatic calibration mode or the manual calibration mode through manual input. The manual calibration mode is specially set for the traceability of the calibration device (system) or some other needs.

[0056] S2. After the first controller in the central processing module or the second controller in the intelligent terminal device receives the user's command signal, it sends a control signal, and transmits the control signal to the electrocardiogram diagnosis and analysis system through the communication module. After receiving the control signal, the electrocardiogram diagnosis and analysis system makes corresponding adjustment settings for filtering, sensitivity, speed, etc.;

[0057] S3. After the adjustment settings are completed, the electrocardiogram diagnosis and analysis system generates a ready signal and information related to the electrocardiogram diagnosis and analysis system (such as brand, model, serial number, hardware version number, software version number, etc.), and transmits it back to the central processing module or the intelligent terminal device through the communication module. The intelligent terminal device then transmits the ready signal to the central processing module through the communication module;

[0058] S4. After receiving the ready signal, the central processing module device sends a control signal corresponding to the waveform to the weak signal module, and at the same time reserves a copy of the data for use by the first anti-cheating algorithm module or the second anti-cheating algorithm module when needed; the weak signal module outputs a corresponding weak analog signal to the electrocardiogram diagnosis and analysis system according to the control signal corresponding to the waveform;

[0059] S5. The electrocardiogram diagnosis and analysis system analyzes the weak analog signal to obtain a waveform data signal, and transmits it back to the central processing module or the intelligent terminal device through the communication module, or converts the waveform data signal into image data through the image acquisition module and transmits it back to the intelligent terminal device;

[0060] S6. The central processing module or the intelligent terminal performs anti-cheating algorithm processing and image data algorithm analysis on the waveform data signal or the image data, judges whether there is a cheating behavior in the electrocardiogram diagnosis and analysis system, judges whether the analysis result of the waveform data signal or the image data meets the requirements, and finally presents the result through the human-computer communication module, and transmits it to the intelligent terminal device as needed or uploads it to the remote server through the intelligent terminal device.

[0061] The existing verification is to output a fixed waveform to the electrocardiogram diagnosis and analysis system, and then make a judgment on whether it is qualified by manually measuring and analyzing the printed electrocardiogram; one of the automatic verifications mentioned in this application is to perform automatic verification through the communication module, but this process is very likely to make it possible for bad manufacturers to have cheating ideas without interference;

[0062] Therefore, the present invention can solve this problem by randomly changing some parameters of the waveform within a certain range in terms of amplitude and time. For example, according to the existing verification regulation JJG1041-2008, for the determination of the internal calibration voltage error term, a square wave of 2.5 Hz and 1 mV is output to the electrocardiograph. In this application, the fixed 2.5 Hz and 1 mV can be changed to (2 - 3) Hz and (0.9 - 1.1) mV, and similar adjustments can be made for other verification items. In this way, the cheating behavior of bad manufacturers by simply outputting the corresponding values of 1.0 mV or the voltage within (0.95 - 1.05) mV can be nipped in the bud; this application also strengthens the anti-cheating method, that is, by randomly comparing the waveform information data transmitted back by the electrocardiogram diagnosis analysis system with the image analysis results of the printed electrocardiogram, if the difference in the results is outside the reasonable range, it can also be determined as cheating.

[0063] Therefore, the present invention randomly changes the control signal parameters sent by the central processing module, and analyzes and compares the transmitted waveform data signal with the previously reserved data through the first anti-cheating algorithm module or the second anti-cheating algorithm module to determine whether the analysis and comparison results are within the allowable range; or analyzes and compares the analysis results of the image data with the analysis results of the waveform data signal through the second anti-cheating algorithm module to determine whether the analysis and comparison results are within the allowable range. (The anti-cheating algorithm of the present invention is used to explain the present invention but is not limited to the above two methods.)

[0064] If the analysis result of the waveform data signal or the image data is within the allowable range, the test item is qualified, and the judgment of the next item continues; otherwise, it is regarded as unqualified.

[0065] If the results of all items are qualified, the total result is qualified, and a verification certificate is issued according to the output verification data information; otherwise, it is unqualified, and an option box for whether to continue the verification is output for manual selection.

[0066] If not continued, a verification result notice is issued according to the current verification data; if continued, the verification of the next item continues until all are completed, and a verification result notice is issued according to the verification data of all items.

[0067] In summary, the present invention brings a series of technical effects, social benefits and economic benefits: Technical effects: (1) Through program design, the automation of the verification process is realized, eliminating problems such as low efficiency and manual errors caused by manual measurement in past verifications, and greatly improving efficiency;

[0068] (2) It has wireless or wired communication functions and can transmit data to intelligent terminal devices (such as laptops, mobile phones, tablets, etc.) or remote servers. (3) Prevent manufacturers of bad electrocardiogram diagnosis and analysis systems from coping with verification requirements through technical cheating.

[0070] Economic benefits: After the project is completed, there will be certain economic benefits.

[0071] The embodiments described above are only for describing the preferred mode of the present invention, and do not limit the scope of the present invention. Without departing from the design spirit of the present invention, various deformations and improvements made by those of ordinary skill in the art to the technical solution of the present invention shall fall within the protection scope determined by the claims of the present invention.
