Description

Technical Field

[0001] The present invention relates to the technical field of medical equipment, and in particular to an automatic external defibrillator and a power supply method thereof. Background Art

[0002] A defibrillator is an emergency medical device that is not frequently used. It is mainly used for defibrillation treatment of dangerous diseases such as ventricular fibrillation and atrial fibrillation. Defibrillators are divided into AED (automatic defibrillator) and MED (manual defibrillator). AED is mainly used in subways, airports, schools, homes, etc., and the users are generally non-professionals. In the process of emergency rescue, if the user can operate the defibrillator quickly and effectively, the patient's life can be saved to the greatest extent. Therefore, it is recommended that users undergo training and practice a certain number of times before using the defibrillator to rescue patients.

[0003] At present, since AEDs are usually used less frequently, the power supply system is generally a disposable battery (i.e., a non-rechargeable battery, such as a disposable lithium battery). Since disposable batteries are non-rechargeable, their capacity decreases after use and they need to be returned to the factory for replacement, thus increasing after-sales costs and efficiency. In addition, the defibrillators currently used for user training will continue to be used after the training, and users often have power anxiety when practicing with the defibrillator, worrying that the battery power in the defibrillator will be consumed to a low level during practice, which will lead to insufficient power when the patient is actually needed to be rescued, and the defibrillator cannot work properly. It can be seen that how to better meet the power demand of automatic external defibrillators and alleviate users' power anxiety has become one of the problems that urgently need to be improved or solved.

Therefore, the various sequences in the specification and the drawings are only for the purpose of clearly describing a certain embodiment and are not meant to be a required sequence, unless otherwise specified that a certain sequence must be followed.

[0050] The serial numbers of the components in this document, such as "first", "second", etc., are only used to distinguish the objects described and do not have any order or technical meaning. The "connection" and "coupling" mentioned in this application, unless otherwise specified, include direct and indirect connections (couplings).

[0051] Please refer to Figures 1 to 5 In the illustrated embodiment, an automatic external defibrillator is provided, which includes a housing 10 , a power module 20 , a first power supply module 30 a , a second power supply module 30 b and a processor 80 .

[0052] The housing 10 includes a casing 11 and a cover 12. The cover 12 covers the casing 11 and can be flipped relative to the casing 11 to open or close the space between the casing 11 and the cover 12. The cover 12 has an inner surface 121 facing the casing 11. In some embodiments, the inner surface 121 can form a receiving space by being recessed or the like.

[0053] The power module 20 is at least used to output defibrillation shocks. In some embodiments, the power module 20 includes an electrode sheet assembly 21, a defibrillation capacitor 22, and a defibrillation assembly 23. The electrode sheet assembly 21 includes an electrode sheet 211, a cable 212, and an electrode sheet plug 213 connected in sequence. An electrode sheet socket 112 for plugging with the electrode sheet plug 213 is provided on the outer surface 111 of the housing 11. The electrode sheet socket 112 is electrically connected to the defibrillation assembly 23 inside the housing 11. When the automatic external defibrillator is used to defibrillate an object to be defibrillated, the electrode sheet 211 is attached to the object to be defibrillated, and the electrode sheet plug 213 is electrically connected to the electrode sheet socket 112, so that the electrode sheet 211 is electrically connected to the defibrillation assembly 23, thereby transmitting the defibrillation current generated by the defibrillation assembly 23 to the object to be defibrillated.

[0054] The electrode sheet assembly 21 is detachably mounted in the receiving space. When the automatic external defibrillator is not used for defibrillation, the electrode sheet assembly 21 is mounted in the receiving space. When the automatic external defibrillator is used to defibrillate the object to be defibrillated, the electrode sheet assembly 21 can be taken out of the receiving space, and then the electrode sheet 211 is attached to the object to be defibrillated, and the electrode sheet plug 213 is electrically connected to the electrode sheet socket 112, so that the electrode sheet 211 is electrically connected to the defibrillation assembly 23, thereby transmitting the defibrillation current generated by the defibrillation assembly 23 to the object to be defibrillated.

[0055] In some embodiments, the electrode sheet assembly 21 includes a pair of electrode sheets 211 and two cables 212. One end of the cable 212 is connected to the electrode sheet 211, and the other end of the cable 212 is connected to the electrode sheet plug 213. The pair of electrode sheets 211 are electrically connected to the electrode sheet plug 213 through the two cables 212.

[0056] In some embodiments, the electrode sheet assembly 21 further includes an electrode sheet packaging bag 214 that encapsulates at least the electrode sheet 211. Specifically, the electrode sheet packaging bag 214 seals the electrode sheet 211 to prevent the electrode sheet 211 from being damp, dusty or damaged. Of course, in other embodiments, the electrode sheet packaging bag 214 can also seal the electrode sheet 211 and the cable 212.

[0057] In some embodiments, Figure 3 As shown, the defibrillator assembly 23 includes a therapeutic charging module 231, a therapeutic discharge module 232 and a therapeutic parameter module 233. The therapeutic charging module 231 is used to charge to achieve the defibrillation treatment function. For example, the therapeutic charging module 231 charges the defibrillator capacitor 22 based on the voltage provided by the first power supply module 30a and / or the second power supply module 30b.

[0058] The therapeutic discharge module 232 is connected to the electrode pad socket 112 for defibrillation discharge. In some embodiments, the therapeutic discharge module 232 includes a discharge switch connected between the defibrillation capacitor 22 and the electrode pad socket 112. When the discharge switch is turned on, the defibrillation capacitor 22 outputs a discharge voltage to the electrode pad socket 112 through the discharge switch to implement defibrillation discharge.

[0059] The treatment parameter module 233 is used to process the parameter data of the acquired treatment parameters, wherein the treatment parameters refer to physiological parameters directly related to defibrillation, such as ECG signals (ECG parameters) and pacing signals (pacing parameters). In some embodiments, the treatment parameter module 233 stores the algorithm required for defibrillation analysis and / or has the analysis circuit required for defibrillation analysis, and performs algorithm analysis based on the obtained ECG signals to obtain analysis results, such as impedance analysis.

[0060] In addition to being used for defibrillation shock, in other embodiments, the power module 20 may also include other components / devices that require the use of electrical energy. For example, the power module 20 also includes devices that require electrical energy for daily use in automatic external defibrillator equipment, including but not limited to a display screen 24, a sensor assembly 25, a parameter calculation circuit 26, and a communication module 27.

[0061] The display screen 24 can be installed on the outer surface of the cover 12. The display screen 24 is used to display physiological information such as monitoring parameters and an operation interface. The display screen 24 can be a conventional screen with operation buttons set around the display screen 24 for operation. The display screen 24 can also be a touch screen, and operations can be performed directly through the display screen 24.

[0062] The sensor assembly 25 is used to collect monitoring parameter signals of the object to be defibrillated. The sensor assembly 25 may include various types of sensors, and each type of sensor transmits the collected monitoring parameter signals to the automatic external defibrillator.

[0063] The parameter calculation circuit 26 is used to calculate the parameter data of the monitoring parameter according to the monitoring parameter signal. In some embodiments, the parameter calculation circuit 26 includes at least one of an electrocardiogram parameter calculation circuit, a blood oxygen parameter calculation circuit, a blood pressure parameter calculation circuit, a body temperature parameter calculation circuit, and a respiratory parameter calculation circuit, and different parameter calculation circuits 26 are used to process corresponding monitoring parameter signals.

[0064] The communication module 27 is used to communicate with external devices of the automatic external defibrillator to realize data transmission.

[0065] The first power supply module 30a is a rechargeable power supply module. In some embodiments, the first power supply module 30a includes a plurality of first cylindrical cells arranged in parallel, for example, the first cylindrical cells are lithium electronic cells, nickel-metal hydride cells, etc. The series-parallel connection between the plurality of first cylindrical cells can be set according to the voltage required by the power module 20. For example, the first power supply module 30a uses 3 series and 1 parallel, 3 series and 2 parallel, or 4 series and 1 parallel first cylindrical cells, and the packaging specifications thereof are 18650, 21700, or 17500, etc. The plurality of first cylindrical cells are connected end to end, and the connection between the first cylindrical cells is achieved by spot welding of nickel sheets.

[0066] The second power supply module 30b is a non-rechargeable power supply module. In some embodiments, the second power supply module 30b includes a plurality of second cylindrical cells arranged in parallel. For example, the second cylindrical cells are lithium metal cells, alkaline cells, etc. The series-parallel connection between the plurality of second cylindrical cells can be set according to the voltage required by the power module 20. For example, the second power supply module 30b uses 4 series and 1 parallel, 3 series and 1 parallel, or 3 series and 2 parallel second cylindrical cells, and the packaging specifications are 17500, 18650 or 21700. The plurality of second cylindrical cells are connected end to end, and the connection between the second cylindrical cells is achieved by spot welding of nickel sheets.

[0067] In this embodiment, the first power supply module 30a and / or the second power supply module 30b first supplies power to the processor 80 before supplying power to the power-consuming module 20. That is, the basic functions of the first power supply module 30a and the second power supply module 30b include supplying power to the processor 80 so that the processor 80 can supply power to other functions of the automatic external defibrillator (e.g., defibrillation discharge), etc.

[0068] In some embodiments, the processor 80 includes a first power supply end, and the output end of the first power supply module 30a and the output end of the second power supply module 30b can both be connected to the first power supply end. This connection method will enable the one of the first power supply module 30a and the second power supply module 30b that outputs a higher voltage to the first power supply end to power the processor 80. For example, when the output voltage of the first power supply module 30a is higher, the first power supply module 30a powers the processor 80, and the first power supply module 30a outputs electrical energy to the outside so that the output voltage gradually decreases. When the voltage is lower than the voltage output by the second power supply module 30b, the second power supply module 30b powers the processor 80. Figure 1 is a schematic diagram of the connection between the first power supply module 30a and the second power supply module 30b and the processor 80, wherein the anode of the third diode 60c is connected to the output end of the first power supply module 30a, the anode of the fourth diode 60d is connected to the output end of the second power supply module 30b, the cathode of the third diode 60c is connected to the cathode of the fourth diode 60d and then connected to the input end of the voltage regulator circuit LDO, and the output end of the voltage regulator circuit LDO is connected to the first power supply end. In this figure, the third diode 60c is used to prevent the current from flowing back into the first power supply module 30a, and the fourth diode 60d is used to prevent the current from flowing back into the second power supply module 30b. The function of the voltage regulator circuit LDO is to adjust the voltage of the first power supply module 30a or the second power supply module 30b to the voltage required by the processor 80.

[0069] In this embodiment, the first power supply module 30a and / or the second power supply module 30b may supply power to the processor 80, thereby ensuring the normal operation of the processor 80 to the greatest extent.

[0070] In some embodiments, by setting the battery cell configuration inside the power supply module, when both power supply modules are fully charged (100% power), the voltage output by the first power supply module 30a to the first power supply end is higher than the voltage output by the second power supply module 30b to the first power supply end, so that the first power supply module 30a becomes the main power supply for the processor 80.

[0071] After receiving power, the processor 80 acquires the first power supply state of the first power supply module 30a and the second power supply state of the second power supply module 30b.

[0072] In some embodiments, the processor 80 obtains the first electric energy that the first power supply module 30a can output externally as the first power supply state of the first power supply module 30a, and obtains the second electric energy that the second power supply module 30b can output externally as the second power supply state of the second power supply module 30b. The first electric energy can be characterized by parameters such as the voltage that the first power supply module 30a can continuously output externally, the current that it continuously outputs, and the remaining power, which indicates the power supply capacity of the first power supply module 30a. Similarly, the second electric energy can be characterized by parameters such as the voltage that the second power supply module 30b can continuously output externally, the current that it continuously outputs, and the remaining power, which indicates the power supply capacity of the second power supply module 30b. In the following, the first electric energy is characterized by the remaining power of the first power supply module 30a, and the second electric energy is characterized by the remaining power of the second power supply module 30b.

[0073] Regarding the remaining power of the first power supply module 30a, in some embodiments, a power meter 40 is further provided in the automatic external defibrillator. The power meter 40 is used to detect the remaining power of the first power supply module 30a, and the processor 80 communicates with the power meter 40 to obtain the remaining power of the first power supply module 30a detected by the power meter 40, and uses the remaining power of the first power supply module 30a as the first electric energy of the first power supply module 30a. In some embodiments, after not communicating with the processor 80 within a preset first time length, the processor 80 enters sleep mode to stop detecting the remaining power of the first power supply module 30a. For example, after the user controls the automatic external defibrillator to shut down, the processor 80 will stop communicating with the power meter 40, and the power meter 40 will enter sleep mode after not communicating with the processor 80 within 10s, thereby reducing power consumption. After the electricity meter 40 enters sleep mode, the processor 80 sends a wake-up instruction to the electricity meter 40 every second preset time period, and the wake-up instruction is used to control the electricity meter 40 to resume detection of the remaining power of the first power supply module 30a. The electricity meter 40 can continue to enter sleep mode after being awakened to detect the remaining power of the first power supply module 30a. It can be understood that the second time period is greater than the first time period, for example, the first time period is several seconds, and the second time period is several hours.

[0074] For the remaining power of the second power supply module 30b, in some embodiments, the remaining power of the second power supply module 30b can be calculated by subtracting the power consumption of the second power supply module 30b from the total power of the second power supply module 30b, and then the remaining power of the second power supply module 30b is used as the second electric energy of the second power supply module 30b. When the second power supply module 30b outputs current to the outside, the processor 80 collects the current output by the second power supply module 30b, integrates the current output by the second power supply module 30b to obtain the power consumption of the second power supply module 30b, or, when the current output by the second power supply module 30b is small, the processor 80 records the output duration of the second power supply module 30b outputting current to the outside, and calculates the power consumption of the second power supply module 30b according to the preset power consumption value and output duration.

[0075] The automatic external defibrillator device can display the remaining power of the first power supply module 30a and the remaining power of the second power supply module 30b through the display screen 24, so that the user can intuitively view the first power and the second power. Exemplarily, the remaining power of the first power supply module 30a and the remaining power of the second power supply module 30b can be displayed in different colors on the display screen 24. In addition, the remaining power can be displayed graphically. For example, the display screen 24 displays the remaining power of the first power supply module 30a and the remaining power of the second power supply module 30b in a power format, and a full grid means that it is in a fully charged state.

[0076] After acquiring the first electric energy and the second electric energy, the processor 80 determines whether the first power supply module 30a and / or the second power supply module 30b are used to supply power to the power-consuming module 20 according to the first electric energy and the second electric energy. That is, when the processor 80 determines whether the first power supply module 30a is used to supply power to the power-consuming module 20, it not only depends on the first power supply state of the first power supply module 30a itself, but also needs to refer to the second power supply state of the second power supply module 30b. Similarly, when the processor 80 determines whether the second power supply module 30b is used to supply power to the power-consuming module 20, it not only depends on the second power supply state of the second power supply module 30b itself, but also needs to refer to the first power supply state of the first power supply module 30a. Specifically:

[0077] When the first electric energy is higher than the preset first minimum threshold and lower than the electric energy required by the power module 20, and the second electric energy is higher than the preset second minimum threshold and lower than the electric energy required by the power module 20, the processor 80 determines that the first power supply module 30a and the second power supply module 30b supply power to the power module 20, wherein the electric energy required by the power module 20 is not lower than the electric energy required by the power module 20 for one defibrillation shock, and the first minimum threshold and the second minimum threshold are both lower than the electric energy required by the power module 20. For example, the first minimum threshold may be half of the electric energy required by the power module 20, and the second minimum threshold is also half of the electric energy required by the power module 20. In the above embodiment, the first power supply module 30a and the second power supply module 30b cannot assume the responsibility of providing electric energy alone, so the first power supply module 30a and the second power supply module 30b share the responsibility of providing electric energy, thereby extending the use time of the automatic external defibrillator, and enabling the automatic external defibrillator to perform defibrillation shocks in extreme crisis conditions to save lives. It can be seen that the first power supply module 30a does not necessarily stop supplying power to the power module 20 when the first electric energy does not meet the electric energy required by the power module 20. When the second power supply module 30b cannot independently supply power to the power module 20, the first power supply module 30a still needs to assume the responsibility of supplying power.

[0078] When the second electric energy is not less than the electric energy required by the power module 20, and the first electric energy is less than the electric energy required by the power module 20, the processor 80 determines that the second power supply module 30b supplies power to the power module 20, that is, the second power supply module 30b provides power at this time. When the second electric energy is not less than the electric energy required by the power module 20, and the first electric energy is not less than the electric energy required by the power module 20, the processor 80 determines that the second power supply does not supply power to the power module 20. It can be seen that in some embodiments, even if the second electric energy exceeds the electric energy required by the power module 20, the second power supply module 30b may not be used to supply power to the power module 20, but it must be jointly determined based on the first electric energy of the first power supply module 30a.

[0079] It can be seen from this that in the above embodiment, the first power supply module is the "main power supply" of the power-consuming module. When the first power supply state meets the requirements of the power-consuming module, the first power supply module is determined to supply power to the power-consuming module. Only when the first power supply module does not meet the requirements of the power-consuming module, the "power supply responsibility" is considered to be handed over to the second power supply module. The advantage of using the first power supply module as the "main power supply" of the power-consuming module is that the first power supply module is easy to charge and has low cost. At the same time, using the second power supply module as a backup for power supply can provide insurance for the operation of the automatic external defibrillator and avoid insufficient power of the defibrillator due to the user forgetting to charge.

[0080] In some embodiments, the automatic external defibrillator device also includes a first power switch 50a and a second power switch 50b, the first power switch 50a is arranged between the first power supply module 30a and the power module 20, and the second power switch 50b is arranged between the second power supply module 30b and the power module 20, and the processor 80 is used to control the first power switch 50a to be closed so that the first power supply module 30a supplies power to the power module 20, and also control the second power switch 50b to be closed so that the second power supply module 30b supplies power to the power module 20.

[0081] In addition, the determination of which power supply module supplies power to the power module 20 is not immutable. For example, after determining that the second power supply module 30b supplies power to the power module 20, if the user charges the first power supply module 30a in a timely manner, the power supply from the second power supply module 30b can be changed to the first power supply module 30a. In some embodiments, when the first power supply module 30a supplies power to the power module 20, if it is determined that only the second power supply module 30b supplies power to the power module 20, the second power supply module 30b is first controlled to supply power to the power module 20, and then the first power supply module 30a is controlled to stop supplying power to the power module 20. Similarly, when the second power supply module 30b is controlled to supply power to the power module 20, if it is determined that only the first power supply module 30a supplies power to the power module 20, the first power supply module 30a is first controlled to supply power to the power module 20, and then the second power supply module 30b is controlled to stop supplying power to the power module 20. That is to say, when changing from one power supply module to another power supply module, the other power supply module is used to supply power first, so that the power consumption of the power consumption module 20 can be seamlessly connected. Figure 1 For example, if the first power supply module 30a currently supplies power to the power module 20, the first power supply switch 50a is closed and the second power supply switch 50b is opened. If the power supply by the first power supply module 30a is changed to the second power supply module 30b, the second power supply switch 50b is first controlled to be closed, and then the first power supply switch 50a is controlled to be opened.

[0082] In the process of seamless power supply of the power module 20, there is a scenario in which the first power switch 50a and the second power switch 50b are closed at the same time. In some embodiments, the automatic external defibrillator device also includes a first anti-backfeed circuit and a second anti-backfeed circuit, the first anti-backfeed circuit is arranged between the second power supply module 30b and the power module 20, and the second anti-backfeed circuit is arranged between the first power supply module 30a and the power module 20. When the first power switch 50a and the second power switch 50b are both closed, the first anti-backfeed circuit is used to prevent the backfeed current generated by the second power supply module 30b to the first power supply module 30a, and the second anti-backfeed circuit is used to prevent the backfeed current generated by the first power supply module 30a to the second power supply module 30b, so as to improve the safety of power supply.

[0083] In some embodiments, the first anti-backflow circuit includes a first diode 60a. When the first power switch 50a is closed, the positive electrode of the first diode 60a is used to communicate with the first power supply module 30a, and the negative electrode of the first diode 60a is connected to the power module 20. The first diode 60a only allows current to flow from the first power supply module 30a to the power module 20, and does not allow current to flow back into the first power supply module 30a. The second anti-backflow circuit includes a second diode 60b. When the second power switch 50b is closed, the positive electrode of the second diode 60b is used to communicate with the second power supply module 30b, and the negative electrode of the second diode 60b is used to communicate with the power module 20. The second diode 60b only allows current to flow from the second power supply module 30b to the power module 20, and does not allow current to flow back into the second power supply module 30b.

[0084] The following takes the case where the first power supply module 30a and the second power supply module 30b are both fully charged and the first power switch 50a is initially closed as an example to illustrate the power supply process in some embodiments:

[0085] First, the remaining power of the first power supply module 30a gradually decreases when supplying power to the power module 20. When the remaining power of the first power supply module 30a decreases to a certain value, the processor 80 controls the second power supply switch 50b to close first, and then controls the first power supply switch 50a to open, that is, the second power supply module 30b supplies power. Subsequently, based on whether the user charges the first power supply module 30a, different situations can be divided.

[0086] If the user fails to charge the first power supply module 30a in time, the first power supply module 30a is in a low power state. As the second power supply module 30b supplies power, the remaining power of the second power supply module 30b continues to decrease. When the remaining power of the second power supply module 30b also decreases to a certain value, the processor 80 can control the first power supply switch 50a to close again. At this time, the first power supply module 30a and the second power supply module 30b jointly supply power to the power module 20.

[0087] If the user charges the first power supply module 30a in time, when the remaining power of the first power supply module 30a recovers to a certain value, the processor 80 can first control the first power supply switch 50a to close, and then control the second power supply switch 50b to open, that is, change to the first power supply module 30a for power supply.

[0088] In some embodiments, the processor 80 may also directly determine which power supply module provides power based on the relationship between the first power and the second power. For example, when the first power is higher than the second power, it is determined that the first power supply module 30a provides power to the power module 20.

[0089] In some embodiments, when the first electric energy is lower than a preset first electric energy threshold, the processor 80 may output a first prompt message for charging the first power supply module 30a, and when the first electric energy is lower than a preset second electric energy threshold, the processor 80 may output a second prompt message for charging the first power supply module 30a, wherein the second electric energy threshold is lower than the first electric energy threshold, and the second electric energy threshold is greater than or equal to the electric energy required by the power module 20, for example, the second electric energy threshold is greater than the electric energy required for one defibrillation shock by the power module 20, and the first electric energy threshold is greater than the electric energy required for several defibrillation shocks by the power module 20. In addition, the prompt degree of the second prompt message is stronger than the prompt degree of the first prompt message, for example, an indicator light and a buzzer are provided on the automatic external defibrillator, when the first electric energy is lower than the first electric energy threshold, the processor 80 controls the indicator light to flash to prompt charging the first power supply module 30a, and when the first electric energy is lower than the second electric energy threshold, the processor 80 controls the indicator light to flash and the buzzer to sound to prompt charging the first power supply module 30a. It can be seen that the charging prompt for the first power supply module 30a can be divided into stages and intensities. When the first power of the first power supply module 30a is sufficient for the power module 20 to perform defibrillation shocks several times, an alarm of general intensity can be issued. When the first power supply module 30a is about to be unable to support the power module 20 to perform defibrillation shocks, a high-intensity alarm is issued.

[0090] In some embodiments, when the first power supply module 30a supplies power, if the first electric energy is lower than the third electric energy threshold, it is determined whether the second electric energy is not lower than the fourth electric energy threshold. If the second electric energy is not lower than the fourth electric energy threshold, it is determined that the power supply by the first power supply module 30a is changed to the power supply by the second power supply module 30b. Otherwise, the automatic external defibrillator is controlled to shut down, wherein the third electric energy threshold is greater than or equal to the electric energy required by the power module 20, and the fourth electric energy threshold is greater than the third electric energy threshold.

[0091] It can be seen that in the process of the first power supply module 30a supplying power to the power module 20, the whole process may be: the first power supply module 30a supplies power to the power module 20, so that the first electric energy gradually decreases, and when the first electric energy is lower than the first electric energy threshold, the first prompt information for charging the first power supply module 30a is output; if the user fails to charge in time and the first electric energy continues to decrease, so that the first electric energy is lower than the second electric energy threshold, the second prompt information for charging the first power supply module 30a is output; if the user still fails to charge in time and the first electric energy continues to decrease, so that the first electric energy is lower than the third electric energy threshold, the processor 80 determines whether the second electric energy is not lower than the fourth electric energy threshold; if the second electric energy is not lower than the fourth electric energy threshold, the control is changed from power supply by the first power supply module 30a to power supply by the second power supply module 30b.

[0092] In some embodiments, when the second electric energy is lower than a preset fifth electric energy threshold, the processor 80 outputs a prompt message for replacing the second power supply module 30b, wherein the fifth electric energy threshold is greater than or equal to the electric energy required by the power module 20. For example, an indicator light and a buzzer are provided on the automatic external defibrillator. When the second electric energy is lower than the fifth electric energy threshold, the processor 80 controls the indicator light to flash and the buzzer to sound, so as to prompt the user to replace the second power supply module 30b.

[0093] In some embodiments, the housing 10 is provided with a power interface 113, for example, the power interface 113 is a TYPEC interface. The power interface 113 is connected to the processor 80, for example, Figure 1 As shown, the power interface 113 is connected to the processor 80 through the fifth diode 60e, wherein the anode of the fifth diode 60e is connected to the power interface 113, and the cathode of the fifth diode 60e is used to connect to the processor 80. When the power interface 113 is connected to an external power source, the external power source can power the processor 80. That is, in addition to being powered by an internal power supply module, the automatic external defibrillator can also be powered by an external power source.

[0094] In some embodiments, the power interface 113 can also be reused as a charging interface of the first power supply module 30a. The automatic external defibrillator device also includes a charging circuit arranged between the power interface 113 and the first power supply module 30a. The processor 80 is also used to determine whether to send a charging signal to the charging circuit according to the remaining power of the first power supply module 30a when detecting that the power interface 113 is connected to the external power supply. The charging signal is used to control the charging circuit to use the external power supply to charge the first power supply module 30a, wherein the processor 80 can use the existing in-situ detection method or detection circuit to detect the connection between the power interface 113 and the external power supply, which will not be repeated here. Exemplarily, when the processor 80 detects that the power interface 113 is connected to an external power source, the processor 80 compares the remaining power of the first power supply module 30a with the charging threshold. If the remaining power of the first power supply module 30a is lower than the charging threshold, a charging signal is sent to the charging circuit, otherwise, no charging signal is sent to the charging circuit, wherein the charging threshold is less than or equal to the power of the first power supply module 30a in a fully charged state, and the charging threshold is greater than or equal to the remaining power of the first power supply module 30a when the first power can meet the needs of the power module 20. The advantage of reusing the power interface 113 as the charging interface of the first power supply module 30a is that the number of interfaces on the housing 10 can be reduced, and in some scenarios, the user does not need to specifically charge the first power supply module 30a.

[0095] In some embodiments, the charging circuit includes a charging chip 71 and a charging switch 72, the charging chip 71 and the charging switch 72 are sequentially located between the power interface 113 and the first power supply module 30a, and the charging chip 71 is connected to the processor 80. When the charging chip 71 detects that the power interface 113 is connected to the external power supply, it controls the charging switch 72 to close. For example, the charging switch 72 is a MOS tube. When the charging chip 71 detects that the power interface 113 is connected to the external power supply, the MOS tube is controlled to be turned on. After the charging switch 72 is closed, if the charging chip 71 receives a charging signal, the first power supply module 30a is charged using an external power supply. In some embodiments, the processor 80 is also used to send a disconnection control instruction to the charging chip 71 after detecting that the power interface 113 is disconnected from the external power supply, so that the charging chip 71 responds to the disconnection control instruction to control the charging switch 72 to disconnect, so as to reduce the power consumption of the charging chip 71.

[0096] Please refer to Figure 6 The automatic external defibrillator shown in the figure is different from the previous embodiment in that whether the first power supply module 30a supplies power to the power-consuming module 20 is not determined by the processor 80, and whether the second power supply module 30b supplies energy-saving power to the power-consuming module 20 is also not determined by the processor 80.

[0097] In this embodiment, the first power supply module 30a is configured to determine whether to supply power to the power-consuming module 20 based on the first power supply state of the first power supply module 30a and the second power supply state of the second power supply module 30b. The second power supply module 30b is configured to determine whether to supply power to the power-consuming module 20 based on the first power supply state of the first power supply module 30a and the second power supply state of the second power supply module 30b. The following is an example in which the first power supply state includes a first voltage output by the first power supply module 30a to the second power supply terminal, and the second power supply state includes a second voltage output by the second power supply module 30b to the second power supply terminal.

[0098] In this embodiment, the power module 20 includes a second power supply terminal, and the output terminal of the first power supply module 30a and the output terminal of the second power supply module 30b are both connected to the second power supply terminal. When the first voltage is higher than the second voltage, the first power supply module 30a supplies power to the power module 20, and when the second voltage is higher than the first voltage, the second power supply module 30b supplies power to the power module 20. In other words, in this embodiment, it is not specifically controlled which power supply module provides power to the output terminal, but it is determined which power supply module provides power based on the voltage or potential of the two power supply modules themselves.

[0099] In some embodiments, the first power supply module 30a can be used as the main power supply and the second power supply module 30b can be used as the backup. By setting the battery cell configuration inside the power supply module, when both power supply modules are fully charged (100% power), the first voltage is higher than the second voltage. In this way, when the first power supply module 30a and the second power supply module 30b are both fully charged, the first power supply module 30a first supplies power to the power module 20.

[0100] Please refer to Figure 7 The embodiment shown is based on the above-mentioned automatic external defibrillator. In this embodiment, a power supply method for the automatic external defibrillator is also provided, comprising the steps of:

[0101] Step 100: Acquire a first power supply state of the first power supply module 30a.

[0102] Step 200: Acquire the second power supply state of the second power supply module 30b.

[0103] The first electric energy that the first power supply module 30a can output externally is obtained as the first power supply state of the first power supply module 30a, and the second electric energy that the second power supply module 30b can output externally is obtained as the second power supply state of the second power supply module 30b. The first electric energy can be characterized by parameters such as the voltage that the first power supply module 30a can continuously output externally, the current that is continuously output, and the remaining power, which indicates the power supply capacity of the first power supply module 30a. Similarly, the second electric energy can be characterized by parameters such as the voltage that the second power supply module 30b can continuously output externally, the current that is continuously output, and the remaining power, which indicates the power supply capacity of the second power supply module 30b.

[0104] Step 300: Control the first power supply module 30a and / or the second power supply module 30b to supply power to the power-consuming module 20 according to the first power supply state and the second power supply state.

[0105] In some embodiments, when the first electric energy is higher than a preset first minimum threshold and lower than the electric energy required by the power module 20, and the second electric energy is higher than a preset second minimum threshold and lower than the electric energy required by the power module 20, the first power supply module 30a and the second power supply module 30b are controlled to supply power to the power module 20, wherein the electric energy required by the power module 20 is not lower than the electric energy required by the power module 20 for one defibrillation shock, and the first minimum threshold and the second minimum threshold are both lower than the electric energy required by the power module 20. For example, the first minimum threshold may be half of the electric energy required by the power module 20, and the second minimum threshold is also half of the electric energy required by the power module 20. In the above embodiments, the first power supply module 30a and the second power supply module 30b are unable to assume the responsibility of providing electric energy alone, so the first power supply module 30a and the second power supply module 30b share the responsibility of providing electric energy, thereby extending the use time of the automatic external defibrillator, and enabling the automatic external defibrillator to perform defibrillation shocks in extreme crisis conditions to save lives. It can be seen that the first power supply module 30a does not necessarily stop supplying power to the power module 20 when the first electric energy does not meet the electric energy required by the power module 20. When the second power supply module 30b cannot independently supply power to the power module 20, the first power supply module 30a still needs to assume the responsibility of supplying power.

[0106] When the second electric energy is not less than the electric energy required by the power module 20, and the first electric energy is less than the electric energy required by the power module 20, the second power supply module 30b is controlled to supply power to the power module 20, that is, the second power supply module 30b provides power at this time. When the second electric energy is not less than the electric energy required by the power module 20, and the first electric energy is not less than the electric energy required by the power module 20, the second power supply is controlled not to supply power to the power module 20. It can be seen that in some embodiments, even if the second electric energy exceeds the electric energy required by the power module 20, the second power supply module 30b may not be used to supply power to the power module 20, but it must be jointly determined based on the first electric energy of the first power supply module 30a.

[0107] In addition, the determination of which power supply module supplies power to the power module 20 is not immutable. For example, after determining that the second power supply module 30b supplies power to the power module 20, if the user charges the first power supply module 30a in a timely manner, the power supply from the second power supply module 30b can be changed to the first power supply module 30a. In some embodiments, when the first power supply module 30a supplies power to the power module 20, if it is determined that only the second power supply module 30b supplies power to the power module 20, the second power supply module 30b is first controlled to supply power to the power module 20, and then the first power supply module 30a is controlled to stop supplying power to the power module 20. Similarly, when the second power supply module 30b is controlled to supply power to the power module 20, if it is determined that only the first power supply module 30a supplies power to the power module 20, the first power supply module 30a is first controlled to supply power to the power module 20, and then the second power supply module 30b is controlled to stop supplying power to the power module 20. That is to say, when changing from one power supply module to another power supply module, the other power supply module is used to supply power first, so that the power consumption of the power consumption module 20 can be seamlessly connected.

[0108] In some embodiments, when the first electric energy is lower than a preset first electric energy threshold, a first prompt message for charging the first power supply module 30a may be output, and when the first electric energy is lower than a preset second electric energy threshold, a second prompt message for charging the first power supply module 30a may be output, wherein the second electric energy threshold is lower than the first electric energy threshold, and the second electric energy threshold is greater than or equal to the electric energy required by the power module 20, for example, the second electric energy threshold is greater than the electric energy required for one defibrillation shock by the power module 20, and the first electric energy threshold is greater than the electric energy required for several defibrillation shocks by the power module 20. In addition, the prompt degree of the second prompt message is stronger than the prompt degree of the first prompt message, for example, an indicator light and a buzzer are provided on the automatic external defibrillator, when the first electric energy is lower than the first electric energy threshold, the control indicator light flashes to prompt the first power supply module 30a to be charged, and when the first electric energy is lower than the second electric energy threshold, the control indicator light flashes and the buzzer sounds to prompt the first power supply module 30a to be charged. It can be seen that the charging prompt for the first power supply module 30a can be divided into stages and intensities. When the first power of the first power supply module 30a is sufficient for the power module 20 to perform defibrillation shocks several times, an alarm of general intensity can be issued. When the first power supply module 30a is about to be unable to support the power module 20 to perform defibrillation shocks, a high-intensity alarm is issued.

[0109] In some embodiments, when the first power supply module 30a supplies power, if the first electric energy is lower than the third electric energy threshold, it is determined whether the second electric energy is not lower than the fourth electric energy threshold. If the second electric energy is not lower than the fourth electric energy threshold, it is determined that the power supply by the first power supply module 30a is changed to the power supply by the second power supply module 30b. Otherwise, the automatic external defibrillator is controlled to shut down, wherein the third electric energy threshold is greater than or equal to the electric energy required by the power module 20, and the fourth electric energy threshold is greater than the third electric energy threshold.

[0110] It can be seen that in the process of the first power supply module 30a supplying power to the power module 20, the whole process may be: the first power supply module 30a supplies power to the power module 20, so that the first electric energy gradually decreases, and when the first electric energy is lower than the first electric energy threshold, the first prompt information for charging the first power supply module 30a is output; if the user fails to charge in time and the first electric energy continues to decrease, so that the first electric energy is lower than the second electric energy threshold, the second prompt information for charging the first power supply module 30a is output; if the user still fails to charge in time and the first electric energy continues to decrease, so that the first electric energy is lower than the third electric energy threshold, the processor 80 determines whether the second electric energy is not lower than the fourth electric energy threshold; if the second electric energy is not lower than the fourth electric energy threshold, the control is changed from power supply by the first power supply module 30a to power supply by the second power supply module 30b.

[0111] In some embodiments, when the second electric energy is lower than a preset fifth electric energy threshold, a prompt message for replacing the second power supply module 30b is output, wherein the fifth electric energy threshold is greater than or equal to the electric energy required by the power module 20. For example, an indicator light and a buzzer are provided on the automatic external defibrillator. When the second electric energy is lower than the fifth electric energy threshold, the indicator light is controlled to flash and the buzzer sounds to prompt the user to replace the second power supply module 30b.

[0112] The automatic external defibrillator in the above embodiment is provided with a rechargeable first power supply module and a non-rechargeable second power supply module. When it is necessary to power the power-consuming module, the first power supply state of the first power supply module and the second power supply state of the second power supply module are considered at the same time, thereby better meeting the power consumption requirements of the power-consuming module and improving the power consumption reliability of the automatic external defibrillator.
