Description

Technical Field

[0001] The present invention belongs to the technical field of automatic external defibrillators, and in particular relates to an automatic energy replenishing external defibrillator device and a use method thereof. Background Art

[0002] An automatic external defibrillator, also known as an AED device, is a life support device. For patients with cardiac arrest, the existing automatic external defibrillator includes a battery part, a defibrillation therapy function main control part, a high-voltage charging part, and a high-voltage discharge part. The battery part is composed of disposable batteries, most of which are battery packs made of disposable lithium batteries, which serve as a detachable and replaceable component of the external defibrillator. The defibrillation therapy function control part uses one output of the battery pack to output 5V, 3.3V or 2.8V low voltage through a voltage conversion module or chip to supply the logic circuit and analog circuit of the main control part for emergency process timing control and physiological signal detection of the rescued person, as well as charge and discharge timing control and process monitoring during defibrillation therapy. Under the timing control of the main control part, the high-voltage charging part directly uses the output current of the battery to charge the high-voltage energy storage capacitor of the high-voltage charge and discharge part of the external defibrillator after the high-voltage charging control circuit boosts the voltage.

[0003] The current automatic external defibrillators have been using disposable lithium batteries as the power supply components of the equipment. Due to the high purchase and replacement prices, as well as the need for personnel to conduct regular inspections and maintenance of expired accessories, the purchasers of automatic external defibrillators have incurred high maintenance costs and expenses. At the same time, after the batteries and electrodes of many devices have passed their expiration dates, they are in an unreliable working state or are basically idle or even scrapped, resulting in a waste of resources; the high maintenance and replacement costs also hinder the market penetration of AED products and increase the difficulty of entering the home market.

[0004] The Chinese patent publication number is CN116847905A, and the name is a patent application for an automatic external defibrillator and a power supply suitable for non-clinical use. The AED includes: an electrical connector for accommodating a battery pack; at least one capacitor for storing energy; an electrotherapy delivery circuit for delivering energy from the outside as electrotherapy; at least one discharge circuit for internally discharging the energy stored in (one or more) capacitors; a non-clinical power adapter, which is accommodated by the electrical connector; and at least one processor. The (one or more) processor can determine whether the non-clinical power adapter is electrically connected to the electrical connector, determine whether the automatic external defibrillator recognizes the non-clinical power adapter, and / or in the case where the automatic external defibrillator recognizes the non-clinical power adapter, enable the automatic external defibrillator to be supplied with power from the non-clinical power adapter. This patent application cannot solve the problem that the automatic external defibrillator cannot use an external non-disposable power supply for a long time. Summary of the invention

[0026] The present invention is described in detail below with reference to the accompanying drawings.

[0027] like Figure 1 and Figure 3 As shown, an automatic energy replenishing external defibrillator device of the present invention includes: an AED device 1 and an electric energy transmission device Y; the bottom of the AED device 1 has a contact contact C20; the AED device 1 has a boost charging unit C2, an energy storage element E1, a high-voltage charge and discharge control circuit F1, a dormant self-check charge and discharge control circuit F2 and an emergency process main control unit F3; the boost charging unit C2 includes a boost charging circuit C21, the boost charging circuit C21 is connected to a charging control circuit C23, and the charging control circuit C23 is connected to the contact contact C20; the charging control circuit C23 is connected to a low-power warning device C22; the electric energy transmission device Y has a wireless charging receiver X11, and the wireless charging receiver X11 is connected to the energy storage element E1.

[0031] The present invention can eliminate or use a small amount of disposable lithium batteries when meeting various emergency performances and usage scenarios of the external defibrillator. This eliminates the relatively expensive battery replacement and maintenance costs and avoids the problem of waste batteries harming the social environment. By adding a charging device and using the internal energy storage element E1 as the battery of the AED device 1, regular wireless charging of the AED device 1 is achieved.

[0032] There are two embodiments of the internal power supply of the AED device 1 of the present invention: Embodiment 1 which does not use disposable lithium batteries, and Embodiment 2 which uses a small amount of disposable lithium batteries; in addition, there are two embodiments of the cable-free charging method of the AED device 1 of the present invention: Embodiment 3 which uses contact metal contacts, and Embodiment 4 which uses wireless transmission and reception for charging.

[0033] Example 1 like Figure 1 As shown, the high-voltage charge and discharge control circuit F1, the dormant self-check charge and discharge control circuit F2 and the emergency process main control circuit F3; these three parts are used to realize the automatic recognition of the defibrillation physiological signals of the rescued patient, high-voltage charging and discharging treatment, guidance and control of the emergency process, and self-check and maintenance of the whole circuit.

[0034] Optionally, the energy storage element E1 is an internal supercapacitor battery of the external defibrillator, which is used to power the high-voltage charge and discharge control circuit F1, the dormant self-test charge and discharge control circuit F2, and the emergency process main control circuit F3. The contact point C20 is a metal spring contact inside the AED device 1, and the contact point C20 is connected to the contact pin W22 of the embedded groove at the bottom of the AED device 1, and the voltage converted by the wireless charging receiving plate W20 at the bottom of the AED device 1 is introduced into the AED device 1.

[0035] The boost charging circuit C21, the low-power alarm circuit C22 and the intelligent charging control circuit C23 constitute an external defibrillator (AED device 1) with an automatic energy replenishment function. Specifically, the AED device 1 has a cabinet outside; the cabinet of the AED device 1 has a power adapter A1 and a charging base A2.

[0036] like Figure 2 As shown; the energy storage element E1 is an internal power supply composed of a supercapacitor or a rechargeable battery, which is used to power the high-voltage charge and discharge control circuit F1, the dormant self-test charge and discharge control circuit F2 and the emergency process main control circuit F3, so as to realize the emergency function of the AED device 1.

[0037] according to Figure 2 As shown, the high-voltage charge and discharge control circuit F1 includes a fuse and an anti-reverse circuit F101, a switch flyback charging circuit F102, a high-voltage energy storage unit F103, a defibrillation discharge realization unit F104 and an internal discharge load F105 connected in sequence. In this embodiment, the resistance of the internal discharge load F105 is 50Ω.

[0038] The dormant self-checking charge and discharge control circuit F2 comprises a second fuse and an anti-reverse circuit F201, a normally-open voltage stabilizing circuit F202, a dormant self-checking charge and discharge control unit F203 and a charge and discharge detection unit F204 which are connected in sequence.

[0039] The first aid process main control circuit F3 comprises a third fuse and an anti-reverse circuit F301 and a turn-off voltage stabilizing circuit F302 and a first aid process main control unit F303 connected in sequence; the first aid process main control circuit F3 is used to connect to the output target 100 to be defibrillated.

[0040] The dormant self-checking charge and discharge control unit F203 is respectively connected to the turn-off voltage stabilizing circuit F302 and the emergency process main control unit F303; and the dormant self-checking charge and discharge control unit F203 is respectively connected to the switch flyback charging circuit F102, the high-voltage energy storage unit F103 and the defibrillation discharge realization unit F104. The charge and discharge detection unit F204 is respectively connected to the high-voltage energy storage unit F103 and the defibrillation discharge realization unit F104.

[0041] The energy storage element E1 is connected to the first fuse and anti-reverse circuit F101, the second fuse and anti-reverse circuit F201 and the first fuse and anti-reverse circuit F101 respectively. The energy storage element E1 of the automatic external defibrillator has three functions: It is used to directly charge and discharge the high-voltage charge and discharge control circuit F1 at high voltage, so as to provide power to the circuit.

[0042] It is used to provide a normally-on power supply for the ultra-low power basic function self-check and charge-discharge control circuit of the dormant self-check charge-discharge control circuit F2.

[0043] Used to provide a shutoff power supply to the emergency process main control circuit F3.

[0044] Example 2 based on Figure 1 An automated external defibrillator, such as Figure 3 As shown, in this embodiment, the power supply part inside the AED device 1 is designed to provide two power sources: a battery pack B and an energy storage element E1.

[0045] Optionally, the battery pack B is a disposable battery pack. Further, the battery pack B is a disposable lithium battery pack.

[0046] like Figure 3 As shown, the energy storage element E1 and the battery pack B are included.

[0047] Optionally, the energy storage element E1 is a rechargeable battery or a capacitor bank. Specifically, the energy storage element E1 is a capacitor bank having two capacitors connected in series, and further, the capacity of each capacitor is 500 farads.

[0048] The energy storage element E1 has a boost charging unit C2 inside.

[0049] Optionally, the boost charging unit C2 is connected to a power transmission device Y.

[0050] Furthermore, the power transmission device Y is a wireless receiver or a wired magnetic device.

[0051] The output end of the energy storage element E1 is electrically connected to the high voltage charge and discharge control circuit F1, the dormant self-check charge and discharge control circuit F2 and the emergency process main control circuit F3.

[0052] The circuit connecting the energy storage element E1 and the high-voltage charge and discharge control circuit F1 is provided with a second switch K2. One end of the second switch K2 is connected to the high-voltage charge and discharge control circuit F1, and the other end is connected to the energy storage element E1.

[0053] The battery pack B is connected to a first switch K1 , and the other end of the first switch K1 is respectively connected to the high-voltage charge and discharge control circuit F1 and the emergency process main control circuit F3 .

[0054] Specifically, the first switch K1 and the second switch K2 are both electrically controlled switches. The dormant self-test charge and discharge control circuit F2 has a dormant self-test charge and discharge control unit F203, and the dormant self-test charge and discharge control unit F203 is connected to the control ends of the first switch K1 and the second switch K2, respectively. Further, the first switch K1 and the second switch K2 are mutually exclusive switches.

[0055] Optionally, a diode D1 is provided on the circuit between the emergency process main control circuit F3 and the energy storage element E1, one end of the diode D1 is connected to the energy storage element E1, and the other end is connected to the emergency process main control circuit F3. The diode D1 can prevent the current of the battery pack B from flowing into the energy storage element E1.

[0056] In this embodiment, a battery pack B is used to provide emergency charging and discharging power to the AED device 1, and the power required for daily equipment self-test and communication is provided by an energy storage element E1. The energy of the energy storage element E1 is regularly charged and replenished by the external rechargeable component Y through the boost charging unit C2. The energy storage element E1 can ensure fast charging.

[0057] An automatic external defibrillator of this embodiment, when in use: In the non-emergency state, the power used for standby and self-test of the equipment is completely provided by the energy storage element E1, and the output of the battery pack B is turned off by the first switch K1. At this time, the output of the energy storage element E1 provides power to the high-voltage charge and discharge control circuit F1, the sleep self-test charge and discharge control circuit F2 and the emergency process main control circuit F3.

[0058] In the emergency state, if the energy storage element E1 cannot supply power, the first switch K1 is turned on, and the battery pack B supplies power to the high-voltage charge and discharge control circuit F1 and the emergency process main control circuit F3.

[0059] In the standby state of the device, the dormant self-test charge and discharge control unit F203 of the dormant self-test charge and discharge control circuit F2 only has a calendar function and an alarm clock function. The alarm clock function is to wake up the dormant self-test charge and discharge control unit F203 at the set time to perform three self-tests: weekly self-test, monthly self-test, and quarterly self-test.

[0060] The weekly self-test checks whether the basic functional circuits such as battery voltage, power supply circuit, and ECG processing circuit are normal, and performs 2 joules of low-voltage charge and discharge. The 2 joules of charge and discharge test specifically includes charging the high-voltage energy storage unit F103 with 200V, and then the defibrillation discharge realization unit F104 performs internal discharge through the internal 50Ω internal discharge load F105; the 2J internal discharge can verify whether most of the functions of the high-voltage charge and discharge circuit are normal.

[0061] The monthly self-test is based on the weekly self-test and adds a functional test of the emergency process main control circuit F3, including whether the power supply of this part and the functions of the human-computer interaction related components are normal. During the functional test of the emergency process main control circuit F3, since the first switch K1 is disconnected, the power supply can only be provided by the energy storage element E1 through the diode D1.

[0062] The quarterly self-test is a full-function self-test of the equipment. Each functional part of the internal circuit of the AED device 1 must be designed to be able to be self-tested to see if it is functioning normally, including the detection of battery voltage, power supply, communication and 200J charge and discharge functions outside of the cycle.

[0063] If the AED device 1 is not designed with a quarterly self-test, the monthly self-test includes a 200J charge-discharge self-test to check whether the functions of various components of the charge-discharge circuit remain intact when charged to more than 2000 volts.

[0064] The 200J high-voltage charge and discharge can be designed to be provided by the electric energy stored in the energy storage element E1, but the charge and discharge inspection must be set up once a year using battery pack B to prevent the virtual voltage generated by the leakage of the disposable lithium battery from delaying the real emergency treatment.

[0065] When performing the 200J conventional high-voltage charge and discharge self-test step, the high-voltage charging power source of the high-voltage charge and discharge control circuit F1 selects the battery pack B controlled by the first switch K1 or selects the energy storage element E1 controlled by the second switch K2.

[0066] During the annual 200J high-voltage charging self-test of the lithium battery, the dormant self-test charging and discharging control unit F203 turns on the electronic switch of the first switch K1, and the current of the battery pack B supplies power to the switch flyback charging circuit F102 for high-voltage charging. During the 200J charging and discharging self-tests in other months, the energy storage element E1 is used to provide power.

[0067] The energy replenishment design of the internal energy storage element E1 in the above-mentioned embodiment 1 and embodiment 2 has the same functional design scheme and implementation method; however, there are two different specific implementation schemes for charging, namely embodiment 3 and embodiment 4.

[0068] based on Figure 1The automatic external defibrillator shown in the figure, according to embodiment 2, the power supply part inside the AED device 1 is designed as a power supply: an energy storage element E1 that uses an external wireless or contact wired charging component for dynamic energy replenishment, and the specific implementation process is as follows Figure 3 shown.

[0069] The fully charged power of the energy storage element E1 can at least supply the AED device 1 with more than 30 discharges, or complete a first aid work of 6 200 joule discharges and 1 hour of continuous monitoring.

[0070] Designing to store more electricity will support more discharge times and monitoring time. In this case, more energy storage components need to be combined. Energy storage component E1 can completely replace disposable lithium batteries.

[0071] In this embodiment, the energy storage element E1 is charged once a month after performing a monthly self-test of 200 joules. This is because the leakage current inside the energy storage element is relatively large, so the self-discharge is larger than that of a disposable lithium battery. Therefore, timely energy replenishment after the monthly self-test can keep the device in a fully charged state.

[0072] In the actual use scenario of the AED device 1, each AED device 1 is deployed in a rack or cabinet of the AED device 1. Usually, the cabinet / rack of the AED device 1 uses external AC power to power the internal anti-theft alarm and the external WIFI / 4G communication module of the AED device 1. Therefore, a charging base is designed in the rack / cabinet to realize charging for the two embodiments of the present invention.

[0073] Since the AED device 1 needs to be easily taken out of the cabinet / rack, it is impossible to charge the AED device 1 by plugging in a wire.

[0074] Therefore, the charging here is implemented by wireless charging or magnetic spring pin contact charging, ensuring that when the AED device 1 is to be used, the charging structure will not prevent the AED device 1 from being removed from the cabinet or rack.

[0075] Example 3 like Figure 5 , which is a detailed schematic diagram of charging implementation using the magnetic spring pin contact method of this embodiment.

[0076] The automatic energy replenishing external defibrillator device of this embodiment includes: an AED device 1 and an electric energy transmission device Y.

[0077] The power transmission device Y is a charging adapter A1 and a charging base A2.

[0078] The boost charging unit C2 includes a boost charging circuit C21, the boost charging circuit C21 is connected to a charging control circuit C23, the charging control circuit C23 is connected to a contact point C20, and the charging control circuit C23 is connected to a low-power warning device C22.

[0079] The charging base A2 has a limiting groove X12 inside that matches the outer shell at the contact point C20 of the AED device 1. A wireless charging receiver X11 is arranged in the limiting groove X12, and the wireless charging receiver X11 is connected to the energy storage element E1.

[0080] Optionally, the wireless charging receiver X11 is a charging spring pin.

[0081] Optionally, the charging control circuit C23 adopts a single chip microcomputer.

[0082] Optionally, the contact point C20 is a magnetic contact point.

[0083] Optionally, the energy storage element E1 is a capacitor group including 8 to 12 capacitors connected in series, and further, the capacity of each capacitor is 500 farads or higher.

[0084] Optionally, the energy storage element E1 is connected to the charging base A2 via a power adapter A1. The power adapter A1 is a standard USB charger that supports PD charging and meets medical safety standards, and can output 12V5A or 5V12A DC voltage and current to the charging base A2. Optionally, the wireless charging receiver X11 is connected to the V+ and GND output of the power adapter A1.

[0085] Optionally, the outer shell of the charging base A2 is a cabinet or a rack.

[0086] Optionally, the low-power warning device C22 has an LED light and a sound device. Optionally, the low-power warning device C22 has a communication device.

[0087] When the AED device 1 is placed in a cabinet or rack Figure 6 When the AED device 1 is placed on the charging base A2 as shown, the contact point C20 at the bottom of the AED device 1 will contact X11 on the charging base A2, thereby introducing the charging current into the AED device 1. The metal contact of the contact point C20 is embedded in the shell during the injection molding of the shell structure of the AED device 1, ensuring the sealing of the shell of the AED device 1, thereby ensuring the IP55 protection requirements of the AED device 1. The limit groove X12 for positioning the AED device 1 on the charging base A2 can ensure that after the AED device 1 is placed on the charging base A2, the metal contact C20 at the bottom of the AED device 1 can accurately contact the wireless charging receiver X11.

[0088] After the external charging base A2 connects the external electrical energy to the AED device 1 through the contact C20 of the AED device 1, the internal energy storage element E1 is charged through the boost charging circuit C21 under the monitoring of the charging control circuit C23. When the charging control circuit C23 detects that the charging is completed, it will cut off the power input of the contact C20.

[0089] When the charging control circuit C23 detects that the voltage on the AED device 1 is lower than the set threshold, it will reconnect the power input inside the boost charging circuit C21 to start charging, or start controlling charging after each 200J self-check.

[0090] When the charging control circuit C23 detects that the AED device 1 is in standby mode and the voltage on the energy storage element E1 is lower than the set threshold, but the input charging voltage is not detected, causing the AED device 1 to be unable to charge, the low-power warning device C22 is controlled to sound and LED indicator light warnings, or send a message to the administrator to prompt the maintenance personnel to charge in time.

[0091] Example 4 like Figure 7 Shown is a schematic diagram of the structure of a wireless charging base A2 for wireless charging.

[0092] The automatic energy replenishment external defibrillator device of this embodiment includes: an AED device 1 and an electric energy transmission device Y.

[0093] Optionally, the charging base A2 of the AED device 1 uses a standard USB charging adapter A1 that supports the PD charging protocol and output voltage as an input power source, which is easy to implement and use.

[0094] The AED device 1 comprises: a boost charging unit C2, an energy storage element E1, a high-voltage charge and discharge control circuit F1, a dormant self-check charge and discharge control circuit F2 and an emergency process main control circuit F3.

[0095] The bottom of the AED device 1 is connected to a wireless charging receiving device W20, which includes a wireless charging receiving plate W21, which has a fixing hole W23, and a contact pin W22 on the back of the wireless charging receiving plate W21. The contact pin W22 is connected to the contact point C20.

[0096] Optionally, the contact pin W22 is a magnetic spring pin.

[0097] The boost charging unit C2 includes a boost charging circuit C21, the boost charging circuit C21 is connected to a charging control circuit C23, the charging control circuit C23 is connected to a contact point C20, and the charging control circuit C23 is connected to a low-power warning device C22.

[0098] The upper part of the charging base A2 has a limit frame W12 that matches the outer shell of the AED device 1. A wireless charging receiving coil W11 is arranged in the limit frame W12. The wireless charging receiving coil W11 is aligned with the receiving coil W20 at the bottom of the AED device 1. In this way, when the AED device 1 is placed on the wireless charging base A2, the wireless charging receiving coil W11 and the receiving coil W20 are tightly attached to each other, with the largest overlapping area, thereby achieving the maximum wireless charging efficiency.

[0099] Optionally, the charging control circuit C23 adopts a single chip microcomputer.

[0100] Optionally, the contact point C20 is a magnetic contact point.

[0101] Optionally, the energy storage element E1 is a capacitor group including 8 to 12 capacitors connected in series, and further, the capacity of each capacitor is 500 farads.

[0102] Optionally, the power adapter A1 is a standard USB charger that meets medical safety standards and supports PD charging, and can output 12V5A or 5V12A DC voltage and current to the charging base A2.

[0103] Optionally, the converted current output of the wireless charging receiving device W20 is connected to the spring contact pin C20 at the bottom of the embedded AED through the metal contacts on the back of the wireless charging receiving board W21, enters the boost charging current C21, and charges the energy storage element E1 under the control of the charging control circuit C23.

[0104] Optionally, the AED device 1 has a cabinet outside or is installed on a rack; the charging base A2 is installed and fixed inside the cabinet or on the rack of the AED device 1.

[0105] Optionally, the low-power warning device C22 has an LED light and a sound device. Optionally, the low-power warning device C22 has a communication device.

[0106] The basic structure of the charging base A2 located at the bottom of the cabinet is as follows Figure 8 As shown, the charging base A2 includes a wireless charging base W10, a wireless charging transmission line board W11, and a limit frame W12.

[0107] When the AED device 1 is placed on the wireless charging base W10, the wireless charging receiving plate at the bottom of the AED device 1 is directly opposite to the transmitting plate of the charging base, and the distance between them is less than 3 mm, so it has a higher wireless power transmission ratio.

[0108] The wireless charging structure at the bottom of the AED device 1 is as follows Fig. 9 As shown in the left part, a screw fixing hole is designed in the center of the wireless charging receiving board for fixing the detachable wireless charging receiving board W21.

[0109] The wireless charging receiving plate W21 is installed in the groove at the bottom of the AED device 1 , and the outer surface of the wireless charging receiving plate W21 and the bottom plane of the AED device 1 are in the same plane.

[0110] like Fig. 9 As shown, the wireless charging receiving board W21 includes two magnetic spring-type contact pins W22. When the wireless receiving board W21 is fixed to the bottom of the AED device 1 with screws, the contact pins W22 and Figure 1 The contact point C20 in the wireless charging receiving device is turned on, and the power of the wireless charging receiving device W20 is output to the inside of the AED device 1.

[0111] The output voltage of the wireless charging receiving device W20 is 5V or 12V, which is consistent with the support of USB-PD charging output. The metal contact of the contact contact C20 is embedded in the shell during the injection molding of the shell structure of the AED device 1, ensuring the sealing of the shell of the AED device 1, thereby meeting the IP55 protection requirements of the AED device 1. At the same time, the bottom of the AED device 1 has a recessed groove with a diameter matching the size of the wireless charging receiving board W20, which can be used to install the wireless charging receiving board W21 to the bottom of the AED device 1 and keep the bottom surface of the AED device 1 and the wireless charging receiving board W21 in a horizontal plane; the center position of the center of the wireless charging receiving board W21 has a central fixing hole W23, which can facilitate the fixing and removal of the wireless charging receiving board W21. This design not only ensures the convenience of AED access, but also ensures that when the AED device 1 is placed on the base, it is more flexible and has a wider error position contact method than the metal contacts used in Example 3. Using metal contacts may easily lead to poor contact due to stains and uneven placement of the contacts, affecting the smart charging effect and triggering false alarms; using wireless charging in Example 4 can avoid or reduce such charging failures.

[0112] External wireless charging power supply via Figure 1After the wireless charging receiving device W20 and the contact contact C20 connect the external electric energy to the AED device 1, under the monitoring of the charging control circuit C23, the internal energy storage element E1 is charged through the supercapacitor dedicated charging circuit C21. When C23 detects that the charging is completed, it will cut off the power input of C20. When C23 detects that the voltage on the energy storage element E1 is lower than a threshold, it will reconnect the power input inside C21 to start charging, or start controlling the charging after each 200J self-test. When it is detected that the AED device 1 on the energy storage element E1 is in standby mode and the voltage is lower than the set threshold, but the input charging voltage is not detected, causing the AED device 1 to be unable to charge, the low-power warning device C22 is controlled to sound and LED indicator warnings, or send a message to the administrator to prompt the maintenance personnel to charge in time.

[0113] Since the AED device 1 is placed in the cabinet or rack of the AED device 1 in most cases, if the charging circuit of the AED device 1 is designed according to the general charging method, the AED device 1 will always be in a charging state. This is not only unnecessary, but also causes energy waste. Because the external charging control circuit C23 of the AED device 1 detects the voltage on the energy storage element E1 once a day, only when the voltage is lower than a threshold will the charging circuit be turned on for internal charging. The threshold is set to the residual voltage on the energy storage element E1 after an internal discharge of 200 joules when the battery is fully charged. Therefore, it is only charged about once a month.

[0114] Optionally, the energy storage element E1 is made of a high-density lithium-ion energy storage element of 500F to 1000F. This type of supercapacitor has a higher operating voltage, and the charging voltage can reach 3.8V or 4.2V. After multiple groups of supercapacitors are connected in series and parallel, the ideal energy storage effect can be achieved, and more than 20 200 joules of charge and discharge treatment can be achieved. Since the pulse discharge current of the supercapacitor is as high as more than 20 amperes, the charging speed of the high-voltage energy storage capacitor F103 will be able to be completed within 3 to 5 seconds. There is also no phenomenon that the high-voltage charging time becomes 15 to 25 seconds after the battery voltage is reduced, which greatly improves the timeliness of defibrillation treatment. Using supercapacitors as the energy storage battery of the AED device 1 + a charging structure compatible with the IP55 dustproof, moisture-proof and corrosion-resistant protection level, the AED device 1 does not have the problem of replacing batteries.

Other modifications or equivalent substitutions made to the technical solution of the present invention by ordinary technicians in the field should be included in the scope of the claims of the present invention as long as they do not depart from the spirit and scope of the technical solution of the present invention.
