Background
Sudden Cardiac Death (SCD) is a death that occurs outside of the hospital, in the emergency room, or on admission within one hour after symptoms occur due to a variety of causes, which may be ventricular tachycardia, ventricular fibrillation, non-contractility, or non-arrhythmias. The survivors of SCD are less than 5%, so primary prevention (prevention for patients who have not developed cardiac arrest) is particularly important for the vast majority of patients at high risk for SCD.
The incidence of SCD and heart failure after myocardial infarction (myocardial infarction) is very high. Related guidelines suggest that implantable cardioverter-defibrillators (ICDs) or implantable cardiac resynchronization therapy cardioverter-defibrillators (CRT-D) are considered 40 days after myocardial infarction or 90 days after revascularization.
Portable Automatic External Defibrillators (AEDs) allow life-threatening arrhythmic patients to be treated in a timely manner, but are relatively cumbersome to use and do not allow for long-term monitoring of the heart.

The invention aims to provide a wearable defibrillation system to solve the problems that the conventional AED cannot monitor the electrocardio activity of a patient for a long time and is troublesome to use.
The following description refers to the accompanying drawings.
Referring to fig. 1 and 2, an embodiment of the present invention provides a wearable defibrillation system, which includes an upper attachment assembly 1, a lower attachment assembly 2, and a control unit; the upper attachment assembly 1 is connected to the lower attachment assembly 2, preferably by a cable 3; the upper attaching assembly 1 comprises a first attaching unit 11 and a second attaching unit 12 which are in communication connection, wherein the first attaching unit 11 and the second attaching unit 12 are used for being arranged in different target areas so as to acquire different electrocardiosignals; the lower attachment assembly 2 comprises a high voltage module (not shown) which controls the transmission of defibrillation pulses to the first attachment unit 11 based on the electrocardiographic signals acquired by the first attachment unit 11 and the second attachment unit 12, the first attachment unit 11 being further adapted to deliver the defibrillation pulses.
The inventor finds that the collection of electrocardiosignals and the positions of the attaching units have a larger relationship, and in some application scenes, a human body can be divided into five heart sound auscultation areas with different positions, and the five auscultation areas are respectively positioned: the right sternum edge is 2 nd intercostal (2 RSB), the left sternum edge is 2 nd intercostal (2 LSB), the left sternum edge is 3 rd intercostal (3 LSB), the left sternum edge is 4 th intercostal (4 LSB), and the intersection between the 5 th intercostal and the midline of the collarbone (5 LMCL). In the present embodiment, the target area may be set to any one of the above five auscultation areas.
Preferably, the upper attachment assembly 1 is used primarily for acquiring electrocardiographic signals and delivering defibrillation pulses for which the attachment unit is typically positioned near the right side of the sternum, such as to cover the 2RSB auscultation area, in order to ensure that the defibrillation current flows as much as possible through the heart. Based on this, in an alternative embodiment, the first attachment unit 11 is arranged at or near the auscultation area of the 2RSB, which is used for both acquisition of the electrocardiographic signals and for delivering defibrillation pulses. In one embodiment, the first attachment unit 11 is capable of covering a 2RSB auscultation area. Further, the second attachment unit 12 may be disposed at or near the other four auscultation areas, whereby the two attachment units (i.e. the first attachment unit 11 and the second attachment unit 12) of the upper attachment assembly 1 may cover different heart sound auscultation areas, so that different electrocardiographic monitoring vectors may be composed. Still further, the second attachment unit 12 preferably completely covers the four auscultation areas of 2LSB,3LSB,4LSB and 5 LMCL.
The control unit may comprise several microcontrollers, such as a low power consumption Microcontroller (MCU) or the like, which may be provided in the upper attachment assembly 1, in the lower attachment assembly 2, or in both the upper and lower attachment assemblies 1, 2. In an alternative embodiment, the control unit comprises a first microcontroller 111 arranged in the first attachment unit 11 for controlling and logically processing the entire upper attachment assembly 1. Optionally, the first attaching unit 11 and the second attaching unit 12 respectively include an electrocardiograph monitoring module 112, which mainly includes an electrocardiograph front end 1121, a filtering module 1122, and other modules, and are used for electrocardiograph measurement and recording.
Referring to fig. 3, alternatively, the first attaching unit 11 and the second attaching unit 12 respectively include attaching electrodes, for convenience of description, the attaching electrodes included in the first attaching unit 11 are referred to as a first attaching electrode 113, the attaching electrodes included in the second attaching unit 12 are referred to as a second attaching electrode 121, and the first attaching electrode 113 and the second attaching electrode 121 have good electrical conductivity and adhesiveness, for example, can be adhered to the skin of a human body. Optionally, the first attaching unit 11 includes at least one first attaching electrode 113, and the second attaching unit 12 includes at least four second attaching electrodes 121, and positions of the first attaching electrode 113 and the second attaching electrode 121 may be adapted to each auscultation area. In the example shown in fig. 3, the outer shape of the second attaching unit 12 is preferably a triangle or a triangle-like shape, but is not limited to the shape shown in fig. 3. In other embodiments, the second attachment unit 12 may have a circular shape, a directional shape, or an irregular shape. The electrocardiograph front end 1121 is respectively connected with the first attached electrode 113 and the second attached electrode 121, and the high-voltage module is connected with the first attached electrode 113, so that electrocardiograph monitoring or defibrillation pulse distribution is realized. Alternatively, the first attaching unit 11 and/or the second attaching unit 12 may be an integral unit, or may be divided into a plurality of sections insulated from each other, wherein a partial area may be a sound pickup area of heart sounds.
Further, the first attaching unit 11 and/or the second attaching unit 12 further comprise an impedance measuring module 114, and the impedance measuring module 114 is configured to detect an impedance between the first attaching electrode 113 and the lower attaching assembly 2, and/or an impedance between the second attaching electrode 121 and the lower attaching assembly 2. In some embodiments, the lower attachment assembly 2 comprises a plurality of attachment segments, whereby different combinations between the first attachment electrode 113, the second attachment electrode 121 and the plurality of attachment segments of the lower attachment assembly 2 will form a plurality of loops, the impedance measurement module 114 is primarily a low-voltage impedance measurement that can measure the impedance of the different plurality of loops to check whether the first attachment electrode 113, the second attachment electrode 121 and the attachment segments are reliably in contact with the skin. It will be appreciated that all possible combinations of loops are measurable. Still further, the first attaching unit 11 and/or the second attaching unit 12 further include a switch array module 115, where the switch array module 115 is configured to switch and route each line (such as a different signal line, a power supply line, or a defibrillation line).
In the first attaching unit 11, the electrocardiograph signal measured by the electrocardiograph front end 1121 is processed by the filtering module 1122 and then transmitted to the first microcontroller 111. The electrocardiographic signal obtained by the electrocardiographic monitoring module 112 of the second attaching unit 12 needs to be transmitted to the first attaching unit 11, and then transmitted to the first microcontroller 111. Thus, the first microcontroller 111 in the first attachment unit 11 can acquire different electrocardiographic signals of the two attachment units, and confirm the electrocardiographic event thereof. Specifically, when the cardiac rhythm abnormal event is detected in the electrocardiograph signal, the first microcontroller 111 controls the high-voltage module of the lower attachment assembly 2 to generate a high-energy defibrillation pulse, the high-energy defibrillation pulse is transmitted to the first attachment unit 11 through the cable 3, and the defibrillation pulse is sent to the human body and flows through the heart to the lower attachment assembly 2 to form a loop, so that the defibrillation effect is achieved.
So configured, the upper attachment assembly 1 includes the first attachment unit 11 and the second attachment unit 12 that are separated, can completely cover the heart sound auscultation area and compose different electrocardiographic monitoring vectors, and the lower attachment assembly 2 can be extended and attached to a position that does not affect daily life by using the cable 3, so that the whole wearable defibrillation system can be attached to the skin, a device with a large attachment volume in an area close to the heart is avoided, and the device has the functions of realizing long-term monitoring and automatic defibrillation, and is very convenient to use. In addition, the whole wearable defibrillation system can be used for not only delivering defibrillation pulses, but also being used for electrocardiographic monitoring and heart failure monitoring, and effectively avoiding the situation of no sensing and error discharge.
Optionally, the first attachment unit 11 and/or the second attachment unit 12 includes a sensor 116, and the sensor 116 is configured to collect physiological characteristic signals; the control unit adjusts the delivery parameters of the defibrillation pulse based on the physiological characteristic signals acquired by the sensor 116. Preferably, the first attaching unit 11 and the second attaching unit 12 each include a sensor 116. The sensors 116 include, but are not limited to, multi-axis accelerometers, multi-set heart sound sensors, acoustic sensors, body temperature sensors, and lung ventilation sensors, among others. Wherein the multi-axis accelerometer is used to record physical characteristics of the patient or posture of the patient; the heart sound sensors are used for recording heart sounds; the sound sensor is used for recording external environment sounds; the body temperature sensor is used for recording the body temperature; the lung ventilation sensor is used to record lung ventilation. Wherein at least a portion of the physiological characteristic signal acquired by sensor 116 may be used as an auxiliary defibrillation marker, and may be used in the optimization of a defibrillation algorithm by the control unit to effectively reduce false discharges. Furthermore, the control unit adjusts the delivery parameters of the defibrillation pulse according to the optimized defibrillation algorithm. The parameters of the pulse are parameters such as timing, length, frequency, voltage, etc. of the pulse, and those skilled in the art will understand the parameters from the prior art.
Further, the control unit includes a heart failure monitoring module, where the heart failure monitoring module is configured to confirm a heart failure event according to the physiological characteristic signal acquired by the sensor 116. Furthermore, after confirming the heart failure event, the control unit can output diagnosis information or alarm information and the like to assist the doctor in diagnosis.
In some embodiments, the first attachment unit 11 is connected to the second attachment unit 12 by wireless communication. The electrocardiographic signals collected by the electrocardiographic monitoring module 112 of the second attaching unit 12 are transmitted to the first microcontroller 111 through wireless communication. The wireless communication is, for example, but not limited to, bluetooth or Zigbee, etc., so that the first attachment unit 11 and the second attachment unit 12 can be independent from each other, and are convenient to wear and use for a long period of time. It will be appreciated that when the first attaching unit 11 is connected to the second attaching unit 12 through wireless communication, the second attaching unit 12 includes a battery, a corresponding processing system (e.g., a second microcontroller) and a corresponding wireless communication module in addition to the electrocardiographic monitoring module 112.
In other embodiments, the first attaching unit 11 is connected to the second attaching unit 12 through a wire, and the electrocardiographic signals collected by the electrocardiographic monitoring module 112 of the second attaching unit 12 are transmitted to the first microcontroller 111 through the wire. Further, the lead wire may be used to transmit not only the electrocardiographic signal but also the power supply and the control signal, so that the second attaching unit 12 may omit the battery and the processing system, and only include the necessary electrocardiographic monitoring module 112, and the battery and the processing system may be disposed in the first attaching unit 11 or the lower attaching assembly 2. Of course in some embodiments the second attachment unit 12 may also be provided with a separate battery and processing system. Alternatively, the first attachment unit 11 may also be provided with a separate battery and processing system. Further, when the first attaching unit 11 and the second attaching unit 12 are connected by a wire, the first microcontroller 111 is configured to form different electrocardiographic monitoring vectors based on different electrocardiographic signals acquired by the first attaching unit 11 and the second attaching unit 12 for better monitoring of electrocardiographic signals.
Optionally, the first attaching unit 11 further includes a wireless communication module 117, where the wireless communication module 117 is mainly configured to transmit the collected electrocardiographic signal and related diagnostic information to an external program control system, and the external program control system may also transmit corresponding configuration information to the wearable defibrillation system. In addition, in the scheme that the first attaching unit 11 and the second attaching unit 12 are connected through wireless communication, the wireless communication module 117 may also be used to realize wireless communication of the first attaching unit 11 and the second attaching unit 12. Optionally, the first attaching unit 11 and/or the second attaching unit 12 further include a storage module 118, where the storage module 118 is mainly used for storing configuration, corresponding electrocardiographic information, diagnostic information, and the like. Optionally, the first attachment unit 11 further comprises a cable socket for detachable connection with the cable 3. It can be understood that when the first attaching unit 11 is separated from the cable 3, the upper attaching assembly 1 can be used alone without the lower attaching assembly 2, and the defibrillation function cannot be realized because the upper attaching assembly 1 only has the functions of electrocardiographic monitoring and heart failure monitoring due to the lack of the high-voltage module. When the first attaching unit 11 is spliced with the cable 3, the upper attaching assembly 1 and the lower attaching assembly 2 work cooperatively, and then the defibrillation function can be realized.
Optionally, referring to fig. 4 and 5, the lower attachment assembly 2 includes at least two attachment sections 25, and all the attachment sections 25 are insulated from each other; the impedance measuring module 114 is configured to detect impedances of at least two of the attaching sections 25 and the upper attaching assembly 1, respectively; the control module selects one of the attachment sections 25 as a main loop end and the remaining attachment sections 25 as auxiliary loop ends based on the impedance detected by the impedance measurement module 114. In the electrocardiographic detection and defibrillation pulse delivery, the upper patch 1 and the lower patch 2 are required to form a loop. The arrangement of at least two attachment sections 25 is substantially redundant with each other. In order to avoid that some attached segments fall off or are not tightly attached, impedance measurement can be periodically performed on each loop path by the impedance measurement module 114, so as to detect whether the attaching degree of each attached segment meets the requirement. Further, in the case of delivering a defibrillation pulse, all of the attachment segments 25 will be simultaneously turned on to maximize the flow path of the defibrillation pulse.
Further, the lower attachment assembly 2 includes a flexible substrate 26 and at least two mutually independent substrates 27, all the substrates 27 are connected to the same surface (referred to as a front surface as shown in fig. 4) of the flexible substrate 26, and the attachment section 25 is disposed on the other surface (referred to as a back surface as shown in fig. 5) of the flexible substrate 26, and is used for being attached to a predetermined portion of a human body; the lower attachment assembly 2 further includes a battery module positioned within one of the substrates 27 and a high voltage module positioned within the other of the substrates 27.

Preferably, all the substrates 27 are arranged along a certain extending direction of the flexible substrate 26 with a gap 28 therebetween to allow the flexible substrate 26 to bend along the extending direction (refer to bending of the flexible substrate 26 in the extending direction, the substrates 27 along with forming a barrel-shaped bend). In the example shown in fig. 4, the lower attachment assembly 2 comprises three of said matrices 27, which are arranged substantially in a left to right direction. It will be appreciated that due to the gaps 28 between the three substrates 27, the flexible substrate 26 is able to flex in a left to right direction to form a barrel-like curved configuration so as to more conformably conform to a predetermined portion of the human body. It should be noted that the above three substrates 27 are only exemplary and not limiting the number of substrates 27. Those skilled in the art may select a greater or lesser number of substrates 27 depending on the actual application.
Preferably, the battery module includes a plurality of cylindrical batteries, the plurality of batteries are arranged along the extending direction (the axial direction of the cylindrical batteries is perpendicular to the extending direction), the base 27 where the battery module is located in the middle of the three base 27, and the base 27 where the battery module is located can be bent along the extending direction. The battery can be a rechargeable battery, for example, the battery can be cylindrical, the outer contour of the middle matrix 27 can be set to be wavy according to the outer contour shape of the battery and is wrapped by adopting a flexible material, so that the matrix 27 where the battery module is located can be bent along the extending direction, the attaching compliance of the lower attaching assembly 2 is further improved, and the lower attaching assembly is more convenient to attach to a human body. The two substrates 27 on both sides can be configured to be rigid and inflexible due to the circuit board provided inside them. It will be appreciated that the positions of the three substrates 27 are not limited to the arrangement shown in the above exemplary embodiment, and those skilled in the art can adjust the arrangement positions of the substrates 27 according to the actual situation.
