[0036] The invention provides a bandage type electrocardiogram detection device.

[0037] In one embodiment of the present invention, Figure 1 and Figure 2As shown, the bandage-type ECG detection device includes a housing and a circuit board arranged in the housing, the housing includes a plurality of conductive detection patches 21 and a switch unit 81, and the circuit board includes a power module 10, an ECG detection module 20, an amplification and shaping circuit 30, a controller 40 and a signal output circuit 50;

[0038] The output end of the power module 10 is connected to the power end of the amplifying and shaping circuit 30 and the power end of the controller 40 respectively, the output end of the electrocardiogram detection module 20 is connected to the input end of the amplifying and shaping circuit 30, the output end of the amplifying and shaping circuit 30 is connected to the AD input end of the controller 40, and the output end of the controller 40 is electrically connected to the signal output circuit 50;

[0039] The power module 10 is used to supply power to the amplifying and shaping circuit 30 and the controller 40;

[0040] The ECG detection module 20 is used to connect with the plurality of conductive detection patches 21 to detect the user's ECG signal and output it to the amplification and shaping circuit 30;

[0041] The amplifying and shaping circuit 30 is used to shape and amplify the detected ECG signal and output it to the controller 40;

[0042] The controller 40 is used to perform analog-to-digital conversion on the ECG signal, and compare the converted first digital electrical signal with a preset digital electrical signal. When there is an error between the first digital electrical signal and the preset digital electrical signal, the first digital electrical signal is multiplied by a preset multiple, and a second digital electrical signal is output to a terminal display device via the signal output circuit 50.

[0043] In this embodiment, the power output by the power module 10 is direct current, which can directly power the amplifying and shaping circuit 30 and the controller 40, so that when the electrocardiograph detection module 20 detects the electrocardiograph signal of the human body, the amplifying and shaping circuit 30 and the controller 40 can work normally and realize amplification, conversion, comparison and other processing of the electrocardiograph signal.

[0044] In this embodiment, the band-aid type means that the ECG detection device has a band-aid-like appearance, is relatively small in size, and has multiple conductive detection patches 21 that can be attached to the skin to detect the ECG signals of the human body. The ECG detection module 20 is the detection end of the band-aid type ECG detection device, which is connected to multiple conductive detection patches 21 to detect the ECG signals of the human body and output them to the amplification and shaping circuit 30 for amplification processing. It can be understood that multiple conductive detection patches 21 are arranged on the shell of the band-aid type ECG detection device and can contact the human skin; that is, multiple conductive detection patches 21 can be attached to the skin of the human heart like a band-aid, so as to detect the ECG signals of the human body. This solution improves the sensitivity and accuracy of detecting the ECG signals of the human body.

[0045] In this embodiment, the amplifying and shaping circuit 30 amplifies and shapes the human ECG signal detected by the ECG detection circuit. Furthermore, the amplifying circuit can obtain an ECG signal with a similar waveform but a larger amplitude through a triode circuit or a field effect tube circuit from a weak ECG signal; shaping is to transform a distorted waveform or a different waveform into an undistorted waveform. It can be understood that the amplifying and shaping circuit 30 amplifies and shapes the input ECG signal to output an ECG signal with a larger amplitude and without distortion to the controller 40 for conversion processing.

[0046] In this embodiment, when the controller 40 receives an ECG signal with a large amplitude and no distortion, it performs analog-to-digital conversion on the ECG signal to convert the analog signal of the ECG signal into a first digital electrical signal. Since there is a preset digital electrical signal inside the controller 40, the controller 40 compares the first digital electrical signal with the preset digital electrical signal. Further, when the first digital electrical signal is less than the preset digital electrical signal, the controller 40 amplifies the first digital electrical signal by a preset multiple, and after amplifying the first digital electrical signal, the second digital electrical signal value terminal display device is output through the signal output circuit 50. It can be understood that after the amplification and shaping circuit 30 amplifies and shapes the ECG signal detected by the ECG detection module 20, there will still be some weak ECG signals output to the controller 40. Therefore, the first digital electrical signal after conversion is compared with the preset digital electrical signal inside the controller 40, and the accuracy of the ECG signal detection by the band-aid type ECG detection device is improved.

[0047] It should be noted that the preset multiple can be 0.5 times, 0.7 times, 1 times, 2 times, etc., and the terminal display device can be a mobile phone, a tablet computer, a wearable device, etc., which is not limited here. In addition, the number of conductive detection patches 21 can be 2, 4, etc., which is set according to the actual application scenario, which is not limited here.

[0048] The technical solution of the present invention detects the ECG signal of the human body by connecting the ECG detection module 20 in the band-aid type ECG detection device with multiple conductive detection patches 21 on the shell, that is, the band-aid type ECG detection device can be attached to the skin of the human heart through multiple conductive detection patches 21 to detect the ECG signal of the human body. After the ECG signal of the human body is detected, it is output to the amplification and shaping circuit 30 for amplification processing, and the amplified ECG signal is output to the AD input end of the controller 40 for analog-to-digital conversion, that is, the analog signal of the ECG signal is converted into a first digital electrical signal, and the first digital electrical signal is compared with the preset digital electrical signal. When there is an error between the converted first digital electrical signal and the preset digital electrical signal, the first digital electrical signal is multiplied by a preset multiple, and the second digital electrical signal is output to the terminal display device through the signal output circuit 50. That is, when the first digital electrical signal is smaller than the preset digital electrical signal, the first digital electrical signal is amplified by a preset multiple; when the first digital electrical signal is larger than the preset digital electrical signal, the first digital electrical signal is reduced by a preset multiple, thereby dynamically adjusting the electrocardiogram signal detected by the electrocardiogram detection module 20 and improving the detection sensitivity of the electrocardiogram signal. The technical solution of the present invention improves the accuracy of the band-aid type electrocardiogram detection device in detecting electrocardiogram signals.

[0049] In one embodiment, the ECG detection module 20 includes a plurality of detection electrodes, and the plurality of detection electrodes are input terminals of the ECG detection module 20;

[0050] Each of the detection electrodes is connected to each of the conductive detection patches 21 for detecting the electrocardiogram (ECG) signals of the human body.

[0051] In this embodiment, the input end of the ECG detection module 20 is the detection electrode of the band-aid type ECG detection device, and each of the multiple detection electrodes is respectively connected to each conductive detection patch 21 on the housing of the band-aid type ECG detection device, so as to detect the user's ECG signal. It can be understood that the conductive detection patch 21 can be a highly sensitive conductive sensing material, so that the ECG signal of the human body can be sensed even when there is sweat on the human skin.

[0052] In one embodiment, if Figure 3 As shown, the controller 40 includes an AD conversion circuit 41 and a comparison circuit 42, the input end of the AD conversion circuit 41 is the AD input end of the controller 40, the output end of the AD conversion circuit 41 is connected to the input end of the comparison circuit 42, and the output end of the comparison circuit 42 is the output end of the controller 40.

[0053] It can be understood that the AD conversion circuit 41 included in the controller 40 in this solution performs analog-to-digital conversion processing on the ECG signal detected by the ECG detection module 20 to convert the detected ECG signal into a first digital electrical signal. The comparison circuit 42 in this solution compares the converted first digital electrical signal with the preset digital electrical signal to amplify the first digital electrical signal and output the second digital signal to the terminal display device for display.

[0054] In one embodiment, if Figure 4 As shown, the band-aid type ECG detection device further includes a first filter circuit 60 and a second filter circuit 70, wherein the first filter circuit 60 is connected between the ECG detection module 20 and the amplification and shaping circuit 30, and the second filter circuit 70 is connected between the controller 40 and the signal output circuit 50;

[0055] The first filtering circuit 60 is used to filter the ECG signal detected by the ECG detection module 20;

[0056] The second filtering circuit 70 is used to filter the ECG signal output by the controller 40 .

[0057] In this embodiment, the first filter circuit 60 performs filtering processing on the detected ECG signal, that is, filtering out the clutter in the ECG signal; the second filter circuit 70 performs filtering processing on the second digital electrical signal output from the controller 40, that is, filtering out the clutter in the second digital electrical signal. In this way, the accuracy of detecting the ECG signal of the human body is improved.

[0059] The switch module 80 is used to control the power module 10 to input power to the amplifying and shaping circuit 30 and the controller 40 .

[0060] In this embodiment, the switch module 80 is an induction switch. It is understandable that the induction switch can be a temperature induction switch, that is, when the band-aid type ECG detection device is attached to human skin, since the human body has a certain temperature, the band-aid type ECG detection device can be turned on by the temperature induction switch to detect the ECG signal of the human body.

[0061] In one embodiment, the signal output circuit 50 includes a wireless transmission module, and the wireless transmission module is used to transmit the second digital electrical signal to the terminal display device. It can be understood that the connection with the terminal display device is achieved through the wireless transmission module included in the signal output circuit 50, so as to transmit the second digital electrical signal to the terminal display device for display. That is, the electrocardiogram signal detected by the band-aid type electrocardiogram detection device is transmitted to the terminal display device, which is convenient for the user to view.

[0062] It should be noted that the wireless transmission module is a Bluetooth module, an NFC module, a cellular mobile communication module or a WIFI module, which is not limited here.

[0063] In one embodiment, the power module 10 is a rechargeable battery or a disposable battery. It is understandable that the rechargeable battery can be a lithium-ion battery, a nickel-hydrogen battery, etc., which is not limited here.
