Description

Technical Field

[0001] The present invention relates to the field of medical devices, and in particular to first aid equipment. Background Art

[0002] An Automated External Defibrillator (AED) is a first aid device, a portable medical first aid device used to rescue patients with sudden cardiac death. As a high-risk product, medical equipment has always had high-quality requirements for hardware design. If a hardware failure occurs during treatment, it can directly threaten the patient's life, health and safety. The hardware system architecture plays a vital role as a key link in the quality of the product hardware. The existing hardware system architecture of medical products is usually composed of a power supply circuit, a main control function circuit and a treatment function circuit. The power supply circuit provides power to the main control function circuit and the treatment function circuit. Since medical products use many ICs and have different power-on sequence requirements, failure to control the power-on sequence or improper use of the power-on sequence can easily cause power backflow problems. Summary of the Invention

[0003] An embodiment of the present invention provides a first aid device, comprising:

[0004] A power supply module, an application module, a first control module and a second control module, wherein the power supply module is used to supply power to the application module and the second control module, the first control module is used to manage the power-on timing of the power supply module, and the second control module is used to manage the product functions of the application module.

[0005] In the first aid device provided by the present invention, a first control module controls the power-on sequence of a power module, which supplies power to the application module and the second control module, thereby preventing power backflow within the power module. The second control module then manages the product functions of the application module, ensuring the normal functioning of the application module and the proper use of its various functions.

[0016] The following will be combined with the drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the described embodiments are part of the embodiments of this application, not all of them. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts should fall within the scope of protection of this application.

[0017] See also Figure 1 , Figure 1 FIG2 is a schematic diagram of the structure of a first aid device according to an embodiment of the present invention. In this embodiment, the first aid device 10 includes a power module 100, an application module 200, a first control module 300, and a second control module 350. The power module 100 is used to supply power to the application module 200 and the second control module 350. The first control module 300 is used to manage the power-on sequence of the power module 100. The second control module 350 is used to manage the product functions of the application module 200.

[0018] The first aid device 10 is an automated external defibrillator (AED). An AED, also known as an automatic external defibrillator, automatic defibrillator, automatic defibrillator, cardiac defibrillator, or fool-proof defibrillator, is a portable medical device that can diagnose specific arrhythmias and deliver defibrillation shocks. It is a medical device that can be used by non-professionals to rescue patients with sudden cardiac death.

[0019] The first control module 300 and the second control module 350 may be processors, which may be microprocessors (also known as microcontroller units (MCUs)) or central processing units (CPUs).

[0020] The second control module 350 is electrically connected to the application module 200 through the pins of the main control chip. The application module 200 is a module that implements the various auxiliary functions of the first aid device 10. The first control module 300 and the second control module 350 can both be a microcontroller unit (MCU) or a central processing unit (CPU). The first control module 300 is used to control the power-on timing of the internal power supply of the power module 100, thereby avoiding the problem of power backflow in the power module 100. The product functions of the application module 200 are then managed through the second control module 350, thereby ensuring the normal product functions of the application module 200 and ensuring the normal use of each product function of the application module 200.

[0021] The product function refers to a function implemented to realize the function of the first aid device 10. For example, sampling data and processing data can be considered as a process of realizing the product function.

[0022] In some embodiments, the power module 100, the application module 200, the first control module 300, and the second control module 350 can be independent modules in terms of location, but functionally interact with each other. In other embodiments, the first control module 300 can be integrated into the power module 100, and the second control module 350 can be integrated into the application module 200, thereby helping to save space occupied by the power module 100, the application module 200, the first control module 300, and the second control module 350, and helping to achieve a compact design of the first aid device 10.

[0023] In the first aid device 10 provided in this embodiment of the present invention, the first control module 300 controls the power-on sequence of the power supply within the power module 100. The power module 100 is used to power the application module 200 and the second control module 350, thereby preventing power backflow between the power module 100 and the application module 200. The second control module 350 then manages the product functions of the application module 200, ensuring that the application module 200 functions properly and that its various functions are functioning normally.

[0024] Please continue reading Figure 2 , Figure 2 is a schematic diagram of the structure of a second first aid device provided in an embodiment of the present invention. The structure of the second first aid device 10 is substantially the same as that of the first first aid device 10, except that, in this embodiment, the application module 200 includes an audio module 210 and a treatment module 220, and the first control module 300 is used to control the power module 100 to power on the application module 200 and to control the treatment module 220 to power on earlier than the audio module 210.

[0025] The audio module 210 is used to send voice prompts to the rescuer. The audio module 210 can be E702T, a control module dedicated to network audio transmission, with a 10 / 100M Ethernet interface 211, which can perform one-way MP3 audio streaming and two-way voice transmission over the network.

[0026] The first control module 300 controls the power module 100 to power up the application module 200. Specifically, it controls the power-up of the treatment module 220 first, and then controls the power-up of the audio module 210. The power module 100 first powers up the application module 200, placing the entire first aid device 10 in a pre-powered state. When defibrillation therapy is required, the power-up of the treatment module 220 is then controlled, thereby preventing power backflow from the treatment module 220. Furthermore, when the first aid device 10 needs to issue a voice prompt to the rescuer, the first control module 300 controls the power-up of the audio module 210, while the second control module 350 controls the audio module 210 to emit the voice prompt, thereby preventing power backflow from the audio module 210 to the treatment module 220. By controlling the power-up sequence of the treatment module 220 and the audio module 210 through the first control module 300 and managing the interaction between the treatment module 220 and the audio module 210 through the second control module 350, the entire first aid device 10 can operate smoothly.

[0027] The treatment module 220 is used to implement the treatment function of the first aid device 10. The structural composition of the treatment module 220 is described in detail below.

[0028] Specifically, the treatment module 220 is connected to the second control module 350. When the second control module 350 determines that treatment is needed, it receives treatment instructions from the second control module 350 and performs automated external defibrillation (AED). AED involves attaching the electrodes of the treatment module 220 to the patient's chest. When the patient's heart rhythm is irregular, the heart is beating but unable to effectively pump blood throughout the body. The electrodes of the treatment module 220 provide an electric shock to correct the situation. For example, in ventricular fibrillation, the heart's electrical activity is chaotic, and the ventricles are unable to effectively pump blood. In ventricular tachycardia, the heart beats too fast and is unable to effectively pump blood. Typically, tachycardia eventually develops into ventricular fibrillation. If left uncorrected, these two types of arrhythmias can rapidly lead to brain damage and death. After the shock, the AED determines whether the patient's heart rhythm has returned to normal or whether another shock is needed. AED can be either semi-automatic or fully-automatic. Semi-automatic external defibrillator therapy will remind the operator to avoid contact with the patient and will not deliver the shock until the operator presses the shock button; fully automatic external defibrillator therapy can automatically deliver the shock to the heart after reminding the operator to leave the patient through sound or display.

[0029] Furthermore, the treatment module 220 includes an automated external defibrillator (AED) treatment unit. Upon receiving a defibrillation rhythm detection result in an ECG signal, the second control module 350 transmits a defibrillation instruction to the AED treatment unit, which then initiates AED analysis, charging, and cardioversion. In other words, upon receiving the defibrillation instruction from the second control module 350, the AED treatment unit does not immediately deliver a shock. Instead, it uses its own defibrillation electrodes to collect the AED ECG waveform, filter it, analyze it, and autonomously perform defibrillation charging and discharging functions. In other words, the defibrillation instruction from the second control module 350 activates the AED treatment unit.

[0030] In addition, the first aid device 10 also includes an electrocardiogram monitoring module 250, and the treatment module 220 also includes a cardiopulmonary resuscitation (CPR) treatment unit. It determines whether cardiopulmonary resuscitation is required based on the detection results of the electrocardiogram detection module. Then, when the second control module 350 receives the information that cardiopulmonary resuscitation is required, it sends an instruction to start the cardiopulmonary resuscitation treatment unit. The cardiopulmonary resuscitation treatment unit performs CPR compression auxiliary guidance, such as guiding the compression frequency and compression depth. It should be noted that in actual products, the cardiopulmonary resuscitation treatment unit can be integrated into the second control module 350 to perform CPR compression auxiliary guidance. At this time, the cardiopulmonary resuscitation treatment unit logically still belongs to the treatment module 220, and therefore still falls within the scope of protection of the present invention.

[0031] Furthermore, the first aid device 10 also includes a display module 260. The second control module 350 is also used to receive a detection result containing a defibrillation rhythm in the ECG signal and when CPR compression is in progress, the audio module 210 sends a message to remind the rescuer to stop CPR compression and sends a defibrillation instruction to the automatic external defibrillation treatment unit. Among them, the audio module 210 and the treatment module 220 are modules with communication functions. That is to say, if a patient is undergoing CPR compression and the ECG detection module detects that defibrillation is required, it is necessary to stop CPR compression and perform defibrillation. A prompt can be issued through the display module 260 or the audio module 210 to remind the rescuer to stop CPR compression and send a defibrillation instruction to the automatic external defibrillation treatment unit, which will analyze and determine whether electric shock defibrillation is required.

[0032] Please continue reading Figure 3 , Figure 3 is a schematic diagram of the structure of the third first aid device provided in an embodiment of the present invention. The structure of the third first aid device 10 is substantially the same as that of the second first aid device 10, except that, in this embodiment, the power supply module 100 includes a first power supply 401 and a second power supply 402. The first power supply 401 is used to power the audio module 210, and the second power supply 402 is used to power the treatment module 220. The first control module 300 is further used to control the power-on timing of the second power supply 402 to be earlier than the power-on timing of the first power supply 401.

[0033] The first power supply 401 does not refer to just one power supply, but may be a collection of multiple power supplies. Similarly, the second power supply 402 does not refer to just one power supply, but may be a collection of multiple power supplies.

[0034] Please continue reading Figure 4 , Figure 4 2 is a schematic diagram of the structure of the fourth first aid device provided by an embodiment of the present invention. The structure of the fourth first aid device 10 is substantially the same as that of the second first aid device 10, except that, in this embodiment, the audio module 210 includes an interface 211, a digital interface unit 212, a digital core unit 213, a digital-to-analog conversion unit 214, and an operational amplifier unit 215. The interface 211 is configured to receive an audio signal. The digital interface unit 212 controls the interface 211 so that the audio signal is transmitted to the digital core unit 213 via the interface 211. The digital core unit 213 processes the audio signal. The digital-to-analog conversion unit 214 converts the processed audio signal into an analog sound signal. The operational amplifier unit 215 amplifies the analog sound signal and outputs it.

[0035] The interface 211 includes an input / output interface 212 for receiving and transmitting digital signals. The audio signal is a digital signal. The audio signal is first received by the interface 211. Then, under the control of the digital interface unit 212, the interface 211 transmits the audio signal to the digital core unit 213 via the interface 211. The digital core unit 213 then processes the audio signal. The digital-to-analog conversion unit 214 then converts the processed audio signal into an analog sound signal. Finally, the operational amplifier unit 215 amplifies the analog sound signal and outputs it through the speaker, thereby generating sound to provide first aid guidance to the rescuer.

[0036] Furthermore, the first aid equipment 10 also includes an audio storage module 216, a power amplifier module 217, a button module 218 and a switch module 219. The second control module 350 is electrically connected to the audio module 210, the audio storage module 216, the power amplifier module 217, the button module 218 and the switch module 219 through the pins of the main control chip. Two pins of the main control chip are electrically connected to a filter circuit, and the filter circuit has an electrolytic capacitor and two capacitors electrically connected. The switch module 219 is provided with a mercury vibration switch, which is electrically connected to the collector of the transistor. The audio module 210 is provided with a capacitor and a resistor, and the capacitor and the resistor are electrically connected accordingly. The audio storage module 216 is electrically connected to the audio module 210. The power amplifier module 217 is provided with a chip MIX2018A, and one side pin of the chip MIX2018A is electrically connected to the capacitor and the resistor, and the other side pin of the chip MIX2018A is electrically connected to the speaker. The button module 218 is electrically connected to the S1 button and the S2 button.

[0037] The first control module 300 is further used to control the power-on timing of the operational amplifier unit 215 to be earlier than the power-on timing of the digital interface unit 212, the power-on timing of the digital interface unit 212 to be earlier than the power-on timing of the digital core unit 213, and the power-on timing of the digital core unit 213 to be earlier than the power-on timing of the digital-to-analog conversion unit 214.

[0038] For the audio module 210, the first control module 300 controls the op amp unit 215 to power on first, followed by the digital interface unit 212, then the digital core unit 213, and finally the digital-to-analog converter unit 214. This timing sequence is consistent with the normal operation of the audio module 210. When the various components within the audio module 210 are powered on using this timing sequence, it can be ensured that power backflow will not occur between the power supplies corresponding to the various components. Furthermore, the second control module 350 is used to control the interactive functions between the op amp unit 215, the digital interface unit 212, the digital core unit 213, and the digital-to-analog converter unit 214. This can ensure that the various components within the audio module 210 can complement each other normally, thereby allowing the audio module 210 to play its due role.

[0039] Please continue reading Figure 5 and Figure 6 , Figure 5 It is a structural diagram of the fifth first aid equipment provided by an embodiment of the present invention. Figure 6 yes Figure 5 Schematic diagram of the power-on timing of the audio module. The structure of the fifth first aid device 10 is substantially the same as that of the fourth first aid device 10, except that, in this embodiment, the power module 100 further includes a third power supply 410, a fourth power supply 420, a fifth power supply 430, and a sixth power supply 440. The third power supply 410 is used to power the operational amplifier unit 215, the fourth power supply 420 is used to power the digital interface unit 212, the fifth power supply 430 is used to power the digital core unit 213, and the sixth power supply 440 is used to power the digital-to-analog conversion unit 214. The first control module 300 is further used to control the power-on timing of the third power supply 410 to be earlier than the power-on timing of the fourth power supply 420, the power-on timing of the fourth power supply 420 to be earlier than the power-on timing of the fifth power supply 430, and the power-on timing of the fifth power supply 430 to be earlier than the power-on timing of the sixth power supply 440.

[0040] The third power supply 410 is not just one power supply, but may be a collection of multiple power supplies. Similarly, the fourth power supply 420, the fifth power supply 430, and the sixth power supply 440 are not just one power supply, but may be a collection of multiple power supplies.

[0041] See Figure 6 , where SPKVDD represents the operational amplifier unit 211, whose voltage value is 5V, IOVDD represents the digital interface unit 212, whose voltage value is 3.3V, DVDD represents the digital core unit 213, whose voltage value is 1.8V, AVDD and HPVDD represent the digital-to-analog conversion unit 214, whose voltage value is 3.3V. Figure 5It can be clearly seen in FIG. 2 that the power-on sequence is the operational amplifier unit 211 , the digital interface unit 212 , the digital core unit 213 and the digital-to-analog conversion unit 214 .

[0042] The power-on timing sequence of the operational amplifier unit 215 , the digital interface unit 212 , the digital core unit 213 , and the digital-to-analog conversion unit 214 has been described above and will not be repeated here.

[0043] The voltage value of the third power supply 410 after power-on is a first voltage, the voltage value of the fourth power supply 420 after power-on is a second voltage, the voltage value of the fifth power supply 430 after power-on is a third voltage, and the voltage value of the sixth power supply 440 after power-on is a fourth voltage. The first voltage is greater than the second voltage, the second voltage is equal to the fourth voltage, and the second voltage is greater than the third voltage.

[0044] And continue to read Figure 6 ,from Figure 6 It can be clearly seen that the maximum power-on voltage value corresponding to the operational amplifier unit 211 is 5V, followed by the power-on voltage values ​​corresponding to the digital interface unit 212 and the digital core unit 213, and the power-on voltage values ​​corresponding to the digital interface unit 212 and the digital core unit 213 remain equal to 3.3V, and finally the power-on voltage value corresponding to the digital-to-analog conversion unit 214 is the minimum, which is 1.8V.

[0045] Similarly, for the audio module 210, the voltage value when the second control module 350 controls the operation of the operational amplifier unit 215 is a first voltage, the voltage value when the digital interface unit 212 is controlled to operate is a second voltage, the voltage value when the digital core unit 213 is controlled to operate is a third voltage, and the voltage value when the digital-to-analog conversion unit 214 is controlled to operate is a fourth voltage, and the first voltage is greater than the second voltage, the second voltage is equal to the fourth voltage, and the second voltage is greater than the third voltage. This voltage value relationship is also consistent with the voltage for normal operation of the audio module 210. When the various components in the audio module 210 use this voltage value to operate normally, it can ensure that the various components operate normally. The power-on timing of the operational amplifier unit 215, the digital interface unit 212, the digital core unit 213, and the digital-to-analog conversion unit 214 is controlled by the first control module 300, and the voltage values ​​of the operational amplifier unit 215, the digital interface unit 212, the digital core unit 213, and the digital-to-analog conversion unit 214 are controlled by the second control module 350, thereby ensuring that the operational amplifier unit 215, the digital interface unit 212, the digital core unit 213, and the digital-to-analog conversion unit 214 maintain normal, stable, and orderly operation.

[0046] Please continue reading Figure 7 , Figure 7is a schematic diagram of the structure of the sixth first aid device provided by an embodiment of the present invention. The structure of the sixth first aid device 10 is substantially the same as that of the fifth first aid device 10, except that, in this embodiment, the operational amplifier unit 215 includes an operational amplifier 215a, and the third power supply 410 is integrated within the operational amplifier unit 215 to power the operational amplifier 215a; the digital interface unit 212 includes an interface controller 212a, and the fourth power supply 420 is integrated within the digital interface unit 212 to power the interface controller 212a; the digital core unit 213 includes a core processor 213a, and the fifth power supply 430 is integrated within the digital core unit 213 to power the core processor 213a; the digital-to-analog conversion unit 214 includes a digital-to-analog converter 214a, and the sixth power supply 440 is integrated within the digital-to-analog conversion unit 214 to power the digital-to-analog converter 214a.

[0047] Op amp 215a, short for operational amplifier, is a circuit unit with a very high amplification factor. In practical circuits, it is often combined with a feedback network to form a functional module. It is an amplifier with a special coupling circuit and feedback. Its output signal can be the result of mathematical operations such as addition, subtraction, differentiation, and integration of the input signal. The operational amplifier was originally designed to convert voltage into digital form for addition, subtraction, multiplication, and division operations. It also became the basic building block of analog computers.

[0048] The interface controller 212a may manage shared network access and provide most of the required reliability and security.

[0049] The core processor 213a is also called the core processor. All calculations, command reception / storage, and data processing in the audio module 210 are performed by the core processor.

[0050] Digital-to-analog converter 214a, also known as a D / A converter, or DAC for short, is a device that converts digital quantities into analog values. A D / A converter essentially consists of four components: a weighted resistor network, an operational amplifier, a reference power supply, and an analog switch. Analog-to-digital converters generally use a digital-to-analog converter 214a. An analog-to-digital converter, also known as an A / D converter, or ADC for short, converts continuous analog signals into discrete digital signals.

[0051] In one embodiment, the third power supply 410 is integrated in the operational amplifier unit 215, the fourth power supply 420 is integrated in the digital interface unit 212, the fifth power supply 430 is integrated in the digital core unit 213, and the sixth power supply 440 is integrated in the digital-to-analog conversion unit 214, thereby improving the integration of the audio module 210.

[0052] It is understandable that in other embodiments, the third power supply 410 , the fourth power supply 420 , the fifth power supply 430 and the sixth power supply 440 may not be integrated into the corresponding units, that is, an external power supply module supplies power to each unit.

[0053] Please continue reading Figure 8 , Figure 8 is a schematic diagram of the structure of the seventh first aid device provided in an embodiment of the present invention. The structure of the seventh first aid device 10 is substantially the same as that of the second first aid device 10, except that, in this embodiment, the treatment module 220 includes a charging unit 221, an energy storage unit 222, a discharge unit 223, and electrode pads 224. The second control module 350 is configured to control the charging unit 221 to charge the energy storage unit 222, control the energy storage unit 222 to supply power to the discharge unit 223, and control the discharge unit 223 to apply a defibrillation voltage to the target subject via the electrode pads 224.

[0054] The second control module 350 is electrically connected to the charging unit 221, the energy storage unit 222, the discharge unit 223 and the electrode sheet 224 through the pins of the main control chip. The charging unit 221 is electrically connected to the charging chip, and one side of the charging chip is electrically connected to the battery and the resistor and then grounded.

[0055] The electrode sheet 224 is also called a defibrillation electrode. The discharge unit 223 in the automatic external defibrillator discharges toward the patient's body through the electrode sheet 224, thereby achieving discharge treatment for the patient.

[0056] When the first aid device 10 is in operation and the discharge unit 223 applies a defibrillation voltage to the target object via the electrode sheet 224 , the second control module 350 is further configured to control the charging unit 221 to continuously supply power to the energy storage unit 222 .

[0057] Specifically, when the defibrillation voltage is applied to the patient using the electrode pads 224, the second control module 350 controls the charging unit 221 of the emergency device 10 to continuously supply power to the energy storage unit 222, so that the energy storage unit 222 has sufficient electrical energy to provide to the discharge unit 223, and then the discharge unit 223 discharges the energy toward the patient through the electrode pads 224 to perform discharge therapy on the patient. By continuously supplying power to the energy storage unit 222 from the charging unit 221, and then to the discharge unit 223 from the energy storage unit 222, the discharge therapy process can be continued, which effectively ensures the continuity of the discharge therapy and avoids the defect of treatment interruption caused by insufficient power in the discharge unit 223.

[0058] When the discharge unit 223 stops applying the defibrillation voltage to the target object, the second control module 350 is further configured to control the charging unit 221 to supply power to the energy storage unit 222 at intervals of a preset time.

[0059] Specifically, when the discharge unit 223 stops discharging toward the patient via the electrode pads 224, the second control module 350 continues to control the charging unit 221 to supply power to the energy storage power source at intervals of a preset duration. This process can be considered a pre-charging process. This is equivalent to charging the energy storage unit 222 to pre-store electrical energy before using the discharge unit 223 to perform discharge therapy on the patient via the electrode pads 224. When the discharge unit 223 needs to be used to discharge toward the patient via the electrode pads 224, the discharge unit 223 can be quickly activated, thereby ensuring the timely delivery of discharge therapy to the patient and ensuring the effectiveness and efficiency of the discharge therapy.

[0060] Please continue reading Figure 9 , Figure 9 is a schematic diagram of the structure of the eighth first aid device provided by an embodiment of the present invention. The structure of the eighth first aid device 10 is substantially the same as that of the seventh first aid device 10, except that, in this embodiment, the treatment module 220 further includes a sensing unit 225. When the electrode sheet 224 is attached to the body of the target subject, the second control module 350 is further configured to control the sensing unit 225 to sense the target subject's impedance value and ECG signal.

[0061] The target object may be considered as a patient who needs discharge treatment. The ECG signal refers to an electrocardiogram signal.

[0062] The above description is merely a specific embodiment of the present application, but the scope of protection of the present application is not limited thereto. Any person skilled in the art can easily conceive of various equivalent modifications or substitutions within the technical scope disclosed in the present application, and such modifications or substitutions should be included in the scope of protection of the present application. Therefore, the scope of protection of the present application should be based on the scope of protection of the claims.
