Please refer to Figures 1 and 2. An embodiment of the present invention provides a wearable defibrillation system, which includes an upper patch component 1 and a lower patch component 2; the upper patch component 1 and the lower patch component 2 Connected by cable 3; the upper patch component 1 is used to collect ECG signals and deliver defibrillation pulses; the lower patch component 2 includes an ECG monitoring module 21, a high voltage module 22 and a control module 23. The electrical monitoring module 21 is used to obtain the ECG signal collected by the upper patch assembly 1; the control module 23 controls the high voltage module 22 to apply the ECG signal to the upper patch based on the ECG signal acquired by the ECG monitoring module 21. Chip assembly 1 delivers defibrillation pulses.

The attachment position of the upper patch component 1 should ensure that good ECG signals can be collected. The entire wearable defibrillation system includes two main functions, one is the ECG detection function, and the other is the defibrillation function. The ECG detection function is mainly realized through the upper patch component 1, the ECG monitoring module 21 and the control module 23. Specifically, the upper patch component 1 is used to collect ECG signals and transmit them to the ECG monitoring module 21. The ECG monitoring module 21 can monitor whether the ECG signals contain abnormal heart rhythm events. The defibrillation function is mainly realized through the upper patch assembly 1, the control module 23 and the high-voltage module 22. Specifically, when an abnormal heart rhythm event is detected in the ECG signal, the control module 23 controls the high-voltage module 22 to generate a high-energy defibrillation pulse. The high-energy defibrillation pulse is transmitted to the upper patch assembly 1 through the cable, and the defibrillation pulse is sent to the human body. The defibrillation pulse and the defibrillation pulse flow through the heart and form a circuit to the lower patch component 2 to achieve the defibrillation effect.

In this configuration, due to the separately arranged upper patch component 1 and lower patch component 2, the upper patch component 1 can be attached to the area close to the heart, and the lower patch component 2 can be extended and attached with the cable 3 without affecting the heart. In the position of daily life, the entire wearable defibrillation system can fit the skin, avoiding the attachment of larger devices near the heart, and realizing long-term monitoring and automatic defibrillation functions. In addition, the entire wearable defibrillation system can be used for both ECG sensing and defibrillation pulse delivery, effectively avoiding unintentional false discharges.

The first patch segment 11 and the second patch segment 12 are insulated from each other; the first patch segment 11 is To collect ECG signals, the second patch segment 12 is used to deliver defibrillation pulses; wherein, the first patch segment 11 and the second patch segment 12 are configured to selectively conduct one of the first patch segment 11 and the other patch segment 12 to turn off. First post clips 11 and 1 The two patch segments 12 can be coupled and connected to the lower patch assembly 2 through cables respectively. It can be understood that both the first patch segment 11 and the second patch segment 12 have good conductivity and adhesion, and can be adhered to human skin, for example. The first patch segment 11 and the second patch segment 12 are set up separately and have different functions. The first patch segment 11 is used to collect ECG signals, while the second patch segment 12 is used to deliver defibrillation pulses. They do not lead at the same time. During the ECG detection process, the second patch segment 12 is closed, and when the defibrillation pulse is sent, the first patch segment 11 is closed.

Further, the upper patch component 1 further includes a third patch segment 13, which is insulated from the first patch segment 11 and the second patch segment 12; the third patch segment 13 is insulated from each other. 13 is used to collect ECG signals; wherein, the first patch segment 11 serves as the main collection end, and the third patch segment 13 serves as an auxiliary collection end; the ECG monitoring module 21 is used to monitor the electrocardiogram according to the first patch segment. 11 and the ECG signal collected by the third patch segment 13 to confirm the ECG event. The third patch segment 13 is mainly a set of redundant patches, which can prevent the first patch segment 11 from falling off or being loosely attached, resulting in failure to collect ECG signals. In particular, when the ECG monitoring module 21 detects certain ECG events, it can simultaneously collect the signals of the first patch segment 11 and the third patch segment 13 and confirm the ECG event based on the two signals. This can effectively avoid measurement deviations caused by interference in a certain patch segment.

Furthermore, when the second patch segment 12 is configured to be turned on, the first patch segment 11 and the third patch segment 13 are turned off; the first patch segment 11 and the third patch segment 13 are closed. When configured to conduct, the second sticker segment 12 is closed.

In the example shown in FIG. 2 , the first sticker segment 11 , the second sticker segment 12 and the third sticker segment 13 are arranged vertically. The second sticker segment 12 is longer and is located in the middle, while the first sticker segment 12 is longer and located in the middle. Fragment 11 is at the bottom, and the third post, fragment 13, is at the top. Of course, in other embodiments, the first sticker segment 11 may also be arranged above and the third sticker segment 13 may be arranged below, and the present invention is not limited to this.

When detecting ECG and delivering defibrillation pulses, the upper patch component 1 and the lower patch component 2 need to form a loop. The arrangement of at least two loop patch segments 25 is essentially redundant to each other. In order to avoid that some patch segments fall off or are not tightly adhered, the impedance measurement module 24 can be used to regularly measure the impedance of each loop path to detect whether the fit degree of each patch segment meets the requirements.

Since the upper patch component 1 includes the first patch segment 11 , the second patch segment 12 and the third patch segment 13 , and the lower patch component 2 includes three loop patch segments 25 , the impedance measurement module 24 can measure different values in the upper and lower patch components. The combined paths are individually measured for impedance. In particular, the impedances between the first patch segment 11 and the three loop patch segments 25 are detected, and according to a certain algorithm, the loop patch segment 25 that fits better among the three loop patch segments 25 is selected as the main path. Perform an ECG test. Table 1 below shows the path screening situation during ECG detection:
