Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present invention.

[0035] It should be noted that the terms "first", "second", etc. in the specification and claims of the present invention and the above-mentioned drawings are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence. It should be understood that the data used in this way can be interchanged where appropriate, so that the embodiments of the present invention described herein can be implemented in an order other than those illustrated or described herein.

[0036] Figure 1 This is a structural diagram of an accuracy analysis device provided by an embodiment of the present invention. This embodiment can be applied to the situation where when there is more than one device to be analyzed, each device to be analyzed is automatically switched and analyzed, and the analysis accuracy of the analyzer is determined based on the analysis result and the actual result. In this embodiment, the analyzer can analyze a cardiac defibrillator, that is, a cardiac defibrillator analyzer.

[0037] like Figure 1 As shown, the precision analysis device includes: an analyzer 10, a high voltage voltage dividing unit 20, a data acquisition unit 30 and a master control unit 40; wherein,

[0038] The first interface int1 of the analyzer 10 is externally connected to at least one device A to be analyzed, and the first interface int1 of the analyzer 10 is also connected to the input end of the high-voltage voltage divider unit 20; the output end of the high-voltage voltage divider unit 20 is connected to the data acquisition unit 30; the main control unit 40 is respectively connected to each device A to be analyzed, the analyzer 10, the high-voltage voltage divider unit 20, and the data acquisition unit 30.

[0039] Exemplarily, the first interface of the analyzer can be in direct contact with the electrode plate of the device to be analyzed, or can be directly connected to the output end of the device to be analyzed. Also, the first interface of the analyzer is internally connected to the input end of the high-voltage voltage divider unit. For example, the input end of the high-voltage voltage divider unit is connected to the first interface in parallel via a line, wherein one end of the input end of the high-voltage voltage divider unit is grounded. Also, the output end of the high-voltage voltage divider unit is connected to the data acquisition unit via an internal line. Also, the master control unit can respectively realize communication connection or line connection with each device to be analyzed, the analyzer, the high-voltage voltage divider unit, and the data acquisition unit.

[0040] When the number of devices A to be analyzed is at least two, and the device A to be analyzed is a defibrillator, the analyzer 10 is used to obtain the analysis result of the target defibrillator and send the analysis result to the main control unit 40, and the target defibrillator is any one of all the defibrillators; the high-voltage voltage divider unit 20 is used to convert the high-voltage voltage sent by the target defibrillator to the analyzer 10 into a low-voltage voltage; the data acquisition unit 30 is used to collect the low-voltage voltage and send the collection result to the main control unit 40; the main control unit 40 is used to determine the actual result of the target defibrillator based on the collection result, and determine the accuracy analysis result of the analyzer 10 based on the target defibrillator based on the actual result and the analysis result.

[0041] Exemplarily, the main control unit can determine the type of the current device to be analyzed, such as whether it is a defibrillator, and can determine which waveform the device to be analyzed is a defibrillator by means of a communication connection. Among them, the type of the device to be analyzed includes a defibrillator, and when the device to be analyzed is a defibrillator, the device to be analyzed can be divided into single-phase wave defibrillators, biphasic wave defibrillators, and multi-pulse bidirectional wave defibrillators according to its waveform characteristics. After the main control unit determines the target defibrillator, a defibrillation instruction can be initiated to the target defibrillator through a communication connection, so that the target defibrillator starts the defibrillation operation according to the defibrillation instruction. When the analyzer receives the defibrillation operation of the target defibrillator, it will perform energy analysis on the defibrillation operation, obtain the analysis result and send the analysis result to the main control unit. At the same time, since the high-voltage voltage divider unit is connected in parallel to the analyzer, when the target defibrillator performs a defibrillation operation on the analyzer, the high-voltage voltage divider unit will also receive the high-voltage voltage acting on the defibrillation operation of the analyzer, and convert the high-voltage voltage to obtain and send the converted low-voltage voltage to the data acquisition unit. At this time, the main control unit can receive the low voltage collected by the data acquisition unit, calculate the actual result of the target defibrillator according to the low voltage, and determine the accuracy analysis result of the analyzer based on the target defibrillator according to the actual result and the analysis result.

[0042] The main control unit 40 is used to switch the target defibrillator to complete the accuracy analysis of the analyzer 10 .

[0043] Exemplarily, assuming that the target defibrillator in the above example is a single-phase wave defibrillator, after obtaining the accuracy analysis result of the analyzer based on the single-phase wave defibrillator according to the above example, the next target defibrillator can be switched, for example, switched to a biphasic wave defibrillator or a multi-pulse bidirectional wave defibrillator, and the accuracy analysis results of the analyzer based on other target defibrillators are continued according to the steps of the above example, until the accuracy analysis results of the analyzer based on all target defibrillators are obtained. Among them, the operation of the master control unit switching the target defibrillator, in one implementation, different defibrillators can be connected together using a universal adapter electrode sheet, and the electrode sheet is directly connected to the first interface of the analyzer. The master control unit switches different defibrillators to start running through a communication method to realize the function of switching different defibrillators. In another implementation, by directly setting an opening and closing circuit on the defibrillator and the electrode sheet, when it is necessary to switch different defibrillators, the function of switching different defibrillators is realized by opening and closing the circuit and controlling the operation start of each defibrillator. It is worth noting that in actual use, the switching of defibrillators can also be realized by other methods, which are not limited too much here.

[0044] The precision analysis device provided by the embodiment of the present invention, on the one hand, can realize the analyzer to obtain the analysis result of the device to be analyzed by connecting the analyzer of the precision analysis device to the external analysis device; and, by connecting the analyzer of the precision analysis device in parallel with the high-voltage voltage divider unit, the high-voltage voltage divider unit is internally connected with the data acquisition unit, so that not only can the data acquisition unit directly collect the voltage of the operation initiated by the device to be analyzed to the analyzer, but also can convert the high voltage voltage into a low voltage that can be read by the data acquisition unit based on the high-voltage voltage divider unit; finally, the main control unit obtains the analysis result of the analyzer on the device to be analyzed and the voltage collected by the data acquisition unit respectively, and can realize the calculation according to the voltage collected by the data acquisition unit to obtain the actual result, and determine the precision analysis result of the analyzer based on the target defibrillator according to the actual result and the analysis result, that is, the precision analysis of the analyzer is realized. On the other hand, since the main control unit can switch different devices to be analyzed and realize the precision analysis of the analyzer based on different devices to be analyzed, the automation process of the precision analysis of the analyzer can be improved. Compared with the current process of precision analysis of the analyzer, the precision analysis device provided by the embodiment of the present invention has a higher level of automation, lower labor costs, and higher efficiency and accuracy in precision analysis.

[0045] Further, Figure 2 A structural diagram of another precision analysis device provided by an embodiment of the present invention, such as Figure 2 As shown, the second interface int2 of the analyzer 10 is externally connected to a variable load accessory 50; the data acquisition unit 30 includes an internal resistance acquisition device 301; wherein,

[0046] The variable load accessory 301 corresponds to at least one load value, and the variable load accessory is connected to the high voltage voltage dividing unit. Optionally, in actual situations, the second interface in this article can be the same interface as the first interface.

[0047] Exemplarily, the load value output by the variable load accessory is 25 ohms, or 50 ohms, or 75 ohms, or 100 ohms, or 125 ohms, or 150 ohms, or 175 ohms, or 200 ohms.

[0048] The internal resistance acquisition device 301 is respectively connected to the variable load accessory 50, the third interface int3 of the analyzer 10, and the main control unit 40, for collecting the actual internal resistance value of the analyzer 10, and sending the actual internal resistance value to the main control unit 40. The actual internal resistance value is determined according to the load value output by the variable load accessory 50 and the standard internal resistance value of the analyzer 10. In actual use, the third interface may be the first interface in this case, or it may be different from the first interface. For example, when the analyzer is a cardiac defibrillator, the third interface is the first interface; when the analyzer is a transcutaneous pacemaker, the third interface is the first interface and a dedicated transcutaneous pacemaker interface. The third interface described in this case is only an illustrative example and should not be used as a limitation.

[0049] Specifically, the internal resistance acquisition device 301 needs to actually measure the internal resistance of the analyzer before formally performing precision analysis on the analyzer. For example, when the analyzer is not connected to a variable load accessory, the standard internal resistance value of the analyzer is 50 ohms. However, at this time, the internal resistance acquisition device 301 is required to determine the actual internal resistance value of the analyzer. And, when the analyzer is connected to a variable load accessory, correspondingly, it is also necessary to determine the actual internal resistance value of the analyzer when the analyzer is connected to a variable load accessory with different load values.

[0050] For example, when the analyzer is not connected to the variable load accessory, its internal resistance is 50 ohms. After the variable load accessory is connected, its internal resistance changes between 25 ohms and 200 ohms. The variable load accessory is connected in parallel with the high voltage divider unit.

[0051] Furthermore, the high-voltage voltage divider unit 20 is a high-voltage voltage divider, and the voltage divider ratio of the high-voltage voltage divider is 1000:1.

[0052] Furthermore, the data acquisition unit 30 further includes a low voltage acquisition device 302, wherein the low voltage acquisition device 302 is an oscilloscope board or an oscilloscope. Alternatively, it can also be a digital multimeter. The internal resistance acquisition device 301 is a digital multimeter.

[0053] The precision analysis device provided by the embodiment of the present invention can change the internal resistance of the analyzer by connecting the analyzer to an external variable load accessory, so as to change the internal resistance of the analyzer when the analyzer analyzes the defibrillation operation of different defibrillators, and obtain more precision analysis comparison data. Among them, since changing the internal resistance of the analyzer can provide a basis for simulating the change of the internal resistance of the human body, therefore, when the analyzer is precision analyzed, by changing the internal resistance of the analyzer, it plays a role in simulating the change of the internal resistance of the human body to a certain extent, receiving the defibrillation operation issued by different defibrillators to the analyzer and analyzing it, and finally obtaining the precision analysis result. Not only does it broaden the calibration of the analysis accuracy of the internal resistance of the analyzer under different circumstances, but it also achieves the simulation of the change of the internal resistance of the human body and completes the calibration of the analysis accuracy of the analyzer.

[0054] In this embodiment, the analyzer 10 can also analyze a transcutaneous pacemaker, that is, a transcutaneous pacemaker analyzer. Specifically,

[0055] When the device A to be analyzed is a transcutaneous pacemaker, the main control unit 40 controls the high voltage divider unit 20 and the data acquisition unit 30 to be turned off. The main control unit 40 is also used to send waveform setting parameters to the transcutaneous pacemaker so that the transcutaneous pacemaker performs pulse operation on the analyzer 10. The analyzer 10 is also used to obtain the pulse analysis result of the transcutaneous pacemaker and send the pulse analysis result to the main control unit 40. The main control unit 40 is also used to determine the accuracy analysis result of the analyzer based on the transcutaneous pacemaker according to the pulse analysis result and the actual pulse result corresponding to the waveform setting parameters.

[0056] Exemplarily, the main control unit can also switch the current device to be analyzed to a transcutaneous pacemaker through a communication method. For example, the transcutaneous pacemaker can be externally connected to the first interface of the analyzer through a line. When it is necessary to switch from a cardiac defibrillator to a transcutaneous pacemaker, all cardiac defibrillators can be directly controlled to be turned off, and only the operation of the transcutaneous pacemaker can be controlled to start. And, when the main control unit determines that the device to be analyzed is a transcutaneous pacemaker, the main control unit will control the high-voltage voltage divider unit and the data acquisition unit to be turned off. At this time, the analyzer-high-voltage voltage divider unit-data acquisition unit path is disconnected, that is, in actual circumstances, the line here is blocked and the collected data cannot be transmitted. After the main control unit controls the high-voltage voltage divider unit and the data acquisition unit to be turned off, a pulse instruction will be sent to the transcutaneous pacemaker so that the transcutaneous pacemaker initiates a pulse operation to the analyzer according to the pulse instruction. Among them, the pulse instruction can be used to indicate the waveform setting parameters of the pulse operation initiated by the transcutaneous pacemaker. The waveform setting parameters are, for example, parameters such as pulse width, frequency, and peak-to-peak voltage. After the analyzer receives the pulse operation initiated by the transcutaneous pacemaker, it can analyze the received information of the pulse operation to obtain the pulse analysis result. And, after the main control unit sends the pulse instruction to the transcutaneous pacemaker, it will calculate the actual pulse result according to the waveform setting parameters. After that, the analyzer will send the pulse analysis result to the main control unit. The main control unit determines the accuracy analysis result of the analyzer based on the transcutaneous pacemaker according to the actual pulse result and the pulse analysis result.

[0057] Optionally, in order to ensure the accuracy of the analyzer's analysis based on a transcutaneous pacemaker, the metering characteristic range of the analyzer can be: internal resistance of 50 ohms-1500 ohms, rate range of 0.1 Hz-13 Hz, pulse width of 2 milliseconds-100 milliseconds, pulse current of 4 mA-200 mA, and pulse energy of 4 mJ-200 mJ.

[0058] Optionally, in order to facilitate the accuracy analysis of the analyzer, the transcutaneous pacemaker can be a waveform generator. That is, in actual situations, the waveform generator can be used instead of the transcutaneous pacemaker.

[0059] The precision analysis device provided by the embodiment of the present invention can not only realize precision analysis and calibration of the analyzer with defibrillator analysis function, but also can realize precision analysis and calibration of the analyzer with transcutaneous pacemaker analysis function based on the transcutaneous pacemaker or the waveform generator that can simulate the pulse operation of the transcutaneous pacemaker, thereby solving the problem that the calibration of the analyzer with transcutaneous pacemaker analysis function is not regulated in the current calibration specification, and realizes precision analysis and calibration of the analyzer with both defibrillator analysis function and transcutaneous pacemaker analysis function. At the same time, the embodiment of the present invention can also realize the switching function between the target defibrillator and the transcutaneous pacemaker or the waveform generator by using the master control unit, thereby improving the automation level in the process of precision analysis of the analyzer and reducing labor consumption.

[0060] Specifically, the accuracy analysis and calibration of the analyzer will be described in detail below.

[0061] Assume that the analyzer's defibrillator analysis function needs to be calibrated for accuracy analysis:

[0062] Before the formal calibration, the main control unit will control the internal resistance acquisition device to turn on, and control the variable load accessories to adjust in sequence according to all the corresponding load values, so that the internal resistance of the analyzer changes according to the current load value corresponding to the variable load accessories. And, during this period, every time the main control unit controls the variable load accessories to adjust the load value once, the main control unit will also control the internal resistance collector to start collecting the actual internal resistance value of the analyzer. For example, if the current load value corresponding to the variable load accessory is 75 ohms, the final actual internal resistance value may be 75.2 ohms. Therefore, in the subsequent accuracy analysis, the internal resistance values ​​involved should all be 75.2 ohms. In addition, the main control unit will also first control the internal resistance acquisition device to measure the standard internal resistance value of the analyzer itself, that is, the actual "standard" internal resistance value of the analyzer when no variable load accessories are connected.

[0063] Among them, when measuring the actual internal resistance value of the analyzer, if the external device to be analyzed is different, the interface connecting the internal resistance collector and the analyzer will change according to the actual situation, which will not be elaborated here.

[0064] When the calibration officially starts, if the main control unit switches to the target defibrillator, the main control unit will control the high-voltage voltage divider unit and the data acquisition unit to turn on, and control the variable load accessories to turn off. Assume that the target defibrillator is a multi-pulse bidirectional wave defibrillator. At this time, the main control unit initiates a first defibrillation instruction to the multi-pulse bidirectional wave defibrillator. Among them, the first defibrillation instruction includes the output energy value corresponding to the defibrillator. The output energy value is generally 6, including the minimum set energy value and the maximum set energy value corresponding to the defibrillator. That is, according to the energy range of the multi-pulse bidirectional wave defibrillator, it can be determined that the minimum set energy value is 2 joules and the maximum set energy value is 200 joules. Therefore, 2 joules, 200 joules and other four energy values ​​between 2-200 joules can be selected as the target output energy value. The main control unit sequentially initiates the first defibrillation instruction of the selected 6 target output energy values ​​to the multi-pulse bidirectional wave defibrillator, and controls the data acquisition unit to collect the corresponding voltage through the high-voltage voltage divider unit. The analyzer analyzes the received defibrillation operation and obtains the analysis result. And, the main control unit receives the collection results collected by the data collection unit, and can calculate the actual results based on the following formula.

[0065]

[0066] Among them, E is the actual result, R is the actual internal resistance value of the analyzer, T is the sampling time interval of the data acquisition unit, r is the voltage division ratio of the high-voltage voltage division unit, and U(n) is the acquisition result (voltage) collected by the data acquisition unit at time n.

[0067] The actual result is calculated according to the above formula, and the analysis result of the analyzer is obtained. The actual result can be subtracted from the analysis result to obtain the final accuracy analysis result of the analyzer based on the multi-pulse bidirectional defibrillator.

[0068] It is worth noting that, due to the analysis process of the multi-pulse bidirectional defibrillator, the multi-pulse bidirectional defibrillator will be controlled to perform defibrillation operations with 6 target output energy values ​​in sequence. Therefore, there are a total of 6 accuracy analysis results based on the multi-pulse bidirectional defibrillator that are finally obtained.

[0069] Afterwards, in order to simulate the influence of the change of the internal resistance of the human body on the accuracy analysis of the analyzer, the control unit will turn on the variable load accessory and control the change of the load value corresponding to the variable load accessory to change the internal resistance of the analyzer. For example, the control unit sequentially controls the load value corresponding to the variable load accessory to become 25 ohms and 200 ohms, or other load values, and controls the multi-pulse bidirectional wave defibrillator to perform defibrillation operation according to the maximum set energy value of 200 joules. In addition, the control unit can obtain the analysis result and the actual result corresponding to the actual internal resistance value according to the above method, and determine the accuracy analysis result of the analyzer based on the multi-pulse bidirectional wave defibrillator at the current actual internal resistance value according to the difference between the analysis result and the actual result.

[0070] It is worth noting that, since different actual internal resistance values ​​are switched, the final accuracy analysis result corresponds to multiple actual internal resistance values.

[0071] And, after analyzing the analyzer based on the multi-pulse biphasic wave defibrillator, the control unit can switch to the next device to be analyzed. If the next device to be analyzed is also a defibrillator, the above steps can also be followed. The energy range of the monophasic wave defibrillator is 2 joules to 360 joules, and the energy range of the biphasic wave defibrillator is 1 joule to 360 joules.

[0072] If the next device to be analyzed is a transcutaneous pacemaker, or a waveform generator is used instead of a transcutaneous pacemaker, then the control unit can control the high-voltage voltage divider unit, the data acquisition unit, and the variable load accessory to be turned off.

[0073] Before officially starting the calibration, the main control unit needs to control the internal resistance acquisition device to start as before, and control the variable load accessories to adjust in sequence according to all the corresponding load values, so that the internal resistance of the analyzer changes according to the current load value corresponding to the variable load accessories. At this time, the analyzer is in the transcutaneous pacemaker function.

[0074] And, when starting calibration, assuming that a waveform generator is used instead of a transcutaneous pacemaker, first, the control unit receives the preset pulse data of the waveform generator, that is, the waveform setting parameters, and calculates the actual pulse result according to the waveform setting parameters. The calculation formula is as follows:

[0075]

[0076] Where V is the pulse voltage, R is the actual internal resistance of the analyzer, I is the pulse current, E is the pulse energy value in one cycle, and t is the pulse width.

[0077] There are five types of operations for analyzing the accuracy of the analyzer:

[0078] (1) The main control unit initiates a first pulse instruction to the waveform generator so that the waveform generator performs a first pulse operation to the analyzer. The first pulse instruction includes a target frequency value issued by the waveform generator, and the target frequency value is a minimum frequency value, a maximum frequency value, and any other four frequency values ​​between 0.1 Hz and 13 Hz. In addition, the waveform generator switches to different target frequency values, and the corresponding rate range covers 6 pacing times per minute (ppm)-780 ppm.

[0079] After receiving the first pulse operation, the analyzer performs pulse analysis on it and obtains a pulse analysis result. The pulse analysis result is the pulse analysis frequency. And, the main control unit can obtain the actual pulse result according to the waveform setting parameters. The actual pulse result is the actual pulse frequency. At this time, the main control unit can calculate the difference between the pulse analysis frequency and the actual pulse frequency, and obtain the accuracy analysis result of the analyzer based on the transcutaneous pacemaker at the target frequency value.

[0080] It is worth noting that, since there are 6 target frequency values, in the accuracy analysis process of adjusting the frequency of the waveform generator, the final accuracy analysis results correspond to 6 different target frequency values.

[0081] In this embodiment, the frequency of the waveform generator is adjusted to simulate and obtain the accuracy analysis result of the analyzer when the transcutaneous pacemaker uses different frequencies to perform pulse operation on the analyzer, thereby realizing the accuracy analysis of the analyzer when receiving pulses of different frequencies.

In addition, the main control unit can obtain the actual pulse width of the pulse according to the waveform setting parameters. Finally, the accuracy analysis result of the analyzer based on the transcutaneous pacemaker at the target pulse width value can also be obtained.

[0084] It is worth noting that, since there are also 6 target pulse width values, in the process of precision analysis of adjusting the pulse width value of the waveform generator, the final precision analysis results correspond to 6 different target pulse width values.

[0085] In this embodiment, the pulse width of the waveform generator is adjusted to simulate and obtain the accuracy analysis result of the analyzer when the transcutaneous pacemaker uses different pulse widths to perform pulse operation on the analyzer, thereby realizing the accuracy analysis of the analyzer when receiving pulses with different pulse widths.

[0086] (3) The main control unit sends a third pulse instruction to the waveform generator, so that the waveform generator performs a third pulse operation on the analyzer. The third pulse instruction includes a peak-to-peak voltage of 10 volts and a target pulse width value, which is a minimum pulse width value, a maximum pulse width value, and any other four pulse width values ​​between 2 milliseconds and 100 milliseconds. The energy range of the pulse sent according to the above instruction covers 4 millijoules to 200 millijoules.

[0087] After receiving the third pulse operation, the analyzer performs pulse analysis on it and obtains the pulse analysis result. The pulse analysis result includes the peak-to-peak voltage and the pulse analysis energy calculated according to the peak-to-peak voltage and the above formula. In addition, the main control unit can calculate the actual pulse result including the actual pulse energy according to the above formula based on the waveform setting parameters. Finally, according to the above process, the accuracy analysis result of the analyzer based on the transcutaneous pacemaker when the peak-to-peak voltage is 10 volts and at the target pulse width value can be obtained.

[0088] In this embodiment, the peak-to-peak voltage of the waveform generator is set to a constant value, and the pulse width of the waveform generator is adjusted. The energy accuracy analysis result of the analyzer is simulated and obtained when the transcutaneous pacemaker is at a constant peak-to-peak voltage and uses different pulse widths to perform pulse operation on the analyzer. The energy accuracy analysis of the analyzer is realized when the peak-to-peak voltage is constant and pulses with different pulse widths are received.

[0089] (4) The main control unit sends a fourth pulse instruction to the waveform generator, so that the waveform generator performs a fourth pulse operation on the analyzer. The fourth pulse instruction includes a target peak-to-peak voltage value set by the waveform generator, and the target peak-to-peak voltage value is a minimum peak-to-peak voltage value, a maximum peak-to-peak voltage value, and any other four peak-to-peak voltage values ​​between 0.2 volts and 10 volts. The pulse sent according to the above instruction has a current range of 4 mA to 200 mA.

[0090] After receiving the fourth pulse operation, the analyzer performs pulse analysis on it and obtains the pulse analysis result. The pulse analysis result includes the peak-to-peak voltage and the pulse analysis current calculated according to the peak-to-peak voltage and the above formula. In addition, the main control unit can calculate the actual pulse result including the actual pulse current according to the above formula based on the waveform setting parameters. Finally, according to the above process, the accuracy analysis results of the analyzer based on the transcutaneous pacemaker at different target peak-to-peak voltage values ​​can be obtained.

[0091] In this embodiment, the peak-to-peak voltage value of the waveform generator is adjusted, and the current accuracy analysis result of the analyzer is simulated and obtained when the transcutaneous pacemaker uses different target peak-to-peak voltage values ​​to perform pulse operation on the analyzer, thereby realizing the current accuracy analysis of the analyzer when receiving rated pulses with different target peak-to-peak voltage values.

[0092] (5) The main control unit sends a fifth pulse instruction to the waveform generator so that the waveform generator performs the fifth pulse operation on the analyzer. The fifth pulse instruction includes a target internal resistance value sent by the waveform generator, and the target internal resistance value is the minimum internal resistance value, the maximum internal resistance value, and any other four internal resistance values ​​between 50 ohms and 1500 ohms. Before the main control unit sends the fifth pulse instruction to the waveform generator, the main control unit also needs to set the internal resistance of the analyzer in advance according to the target internal resistance value. For example, if the current target internal resistance value is 50 ohms, the main control unit needs to set the internal resistance value of the analyzer to 50 ohms in advance.

[0093] After receiving the fifth pulse operation, the analyzer performs pulse analysis on it and obtains the pulse analysis result. The pulse analysis result is the pulse analysis current value and the pulse analysis energy value. And, the main control unit can obtain the actual pulse result according to the waveform setting parameters. The actual pulse result is the actual pulse current value and the actual pulse energy value. At this time, the main control unit can calculate the corresponding difference between the pulse analysis result and the actual pulse result, and obtain the accuracy analysis result of the analyzer based on the transcutaneous pacemaker at the target internal resistance value.

[0094] It is worth noting that, since there are 6 target internal resistance values, in the process of adjusting the accuracy analysis of the internal resistance of the waveform generator, the final accuracy analysis results correspond to 6 different target internal resistance values.

[0095] In this embodiment, the internal resistance of the waveform generator is adjusted to simulate and obtain the accuracy analysis result of the analyzer when the transcutaneous pacemaker uses different internal resistances to perform pulse operation on the analyzer, thereby realizing the accuracy analysis of the analyzer when receiving pulses with different internal resistances.
