[0043] Please see Figures 1 to 4 , Figure 1 This is a schematic diagram of the structure of a vehicle 200 provided in an embodiment of this application. The present application provides a vehicle 200, which includes a defibrillator system 100 according to any embodiment of this application. In the embodiments of this application, the vehicle 200 can be a pure electric vehicle 200, a hybrid electric vehicle 200, a plug-in hybrid electric vehicle 200, a range-extended electric vehicle 200, a gasoline-powered vehicle, etc. The vehicle 200 can also be a sedan, truck, bus, lorry, trailer, etc. The embodiments of this application do not specifically limit the type of vehicle 200.
[0044] This utility model provides a defibrillation system 100 for use in a vehicle 200. The defibrillation system 100 includes a control module 3 and a first defibrillation module 1. The first defibrillation module 1 is disposed outside the passenger compartment 201 of the vehicle 200. The control module 3 is electrically connected to the first defibrillation module 1 and can control the operation of the first defibrillation module 1.
[0045] In some embodiments, the defibrillation system 100 includes a second defibrillation module 2, which is disposed in the passenger compartment 201 of the vehicle 200. The control module 3 is electrically connected to the second defibrillation module 2 and is capable of controlling the operation of the second defibrillation module 2.
[0046] In some embodiments, the defibrillation system 100 includes a monitoring module 4 connected to a control module 3. The monitoring module 4 is used to monitor the time-domain information of the heartbeat and breathing of people around the vehicle 200 or inside the passenger compartment 201.
[0047] In the defibrillation system 100 of this application embodiment, the defibrillation system 100 is used in a vehicle 200. The defibrillation system 100 includes: a control module 3, a first defibrillation module 1, a second defibrillation module 2, and a monitoring module 4. The first defibrillation module 1 is located outside the passenger compartment 201 of the vehicle 200. The control module 3 is electrically connected to the first defibrillation module 1 and can control the operation of the first defibrillation module 1. The second defibrillation module 2 is located inside the passenger compartment 201 of the vehicle 200. The control module 3 is electrically connected to the second defibrillation module 2 and can control the operation of the second defibrillation module 2. The monitoring module 4 is connected to the control module 3 and is used to monitor the time-domain information of the heartbeat and respiration of people around the vehicle 200 or inside the passenger compartment 201. Thus, the first defibrillation module 1, located outside the passenger compartment 201, can perform defibrillation emergency treatment on people outside the passenger compartment 201, effectively responding to emergency needs outside the vehicle 200. The second defibrillation module 2 can perform defibrillation emergency treatment on people inside the passenger compartment 201. Meanwhile, monitoring module 4 can detect the heartbeat and breathing signals of people in the vicinity, accurately identify abnormal heart rates, and, together with the first defibrillator module 1 and the second defibrillator module 2, can achieve rapid response and rescue.
[0048] Specifically, the incidence of cardiovascular disease is increasing year by year, and cardiac arrest has become one of the leading causes of sudden death. Automated external defibrillators (AEDs) can be used as emergency equipment to restore a normal heart rhythm through electrical defibrillation during cardiac arrest. In the emergency process, the timely use of AEDs has a decisive impact on the survival rate of cardiac arrest patients. When a patient experiences malignant arrhythmias such as ventricular fibrillation, timely defibrillation is the fastest and most effective treatment. The survival rate of a resuscitated patient is closely related to the time of defibrillation; with each delay in defibrillation, the patient's survival rate decreases by 7%-10% per minute. If defibrillation is completed within 3 minutes of the incident, the patient's survival rate can reach 70%-80%; if completed within 5 minutes, the survival rate drops to 50%; if completed within 7 minutes, the survival rate drops to 30%; if completed within 9-11 minutes, the survival rate is only 10%; and if completed within 12 minutes, the survival rate is only 2%-5%. In other words, the time required for emergency treatment is crucial to the success of the rescue.
[0049] It should be noted that existing automated external defibrillators (AEDs) are mainly deployed in fixed public places such as airports, subway stations, and shopping malls. These public places can provide power to the AEDs to ensure their normal operation. However, the defibrillation system 100 of this application is directly installed on the vehicle 200, which can move with the user and allows for flexible emergency care. With the aging of society and increased awareness of health and safety, as well as increased travel frequency, the demand for vehicle-mounted defibrillation systems 100 is particularly urgent, especially in remote areas or special environments.
[0050] In this embodiment, to address a patient requiring emergency care outside the vehicle, the first defibrillator module 1 of this embodiment can be used to perform defibrillation on the patient via a control system, thereby saving the patient's life in a timely manner. In this embodiment, the defibrillator system 100 can be used when an accident occurs in the vehicle 200 and a patient requiring defibrillation is present around the vehicle 200. Alternatively, it can be used for patients in other vehicles 200 requiring defibrillation, or for patients in vehicles who have exited the passenger compartment 201 and require defibrillation. Thus, in various scenarios, the defibrillator system 100 of this embodiment can perform defibrillation on individuals outside the passenger compartment 201 of the vehicle 200 via the first defibrillator module 1. This avoids the problem that in-vehicle automated external defibrillators cannot provide emergency care to individuals outside the passenger compartment 201, effectively addressing passenger movement or emergency needs outside the vehicle 200, and improving emergency care efficiency.
[0051] Of course, the first defibrillation module 1 in the embodiments of this application can move freely relative to the passenger cabin 201, so it can also perform defibrillation on patients in the passenger cabin 201 of the vehicle 200.
[0052] In some embodiments, the vehicle 200 further includes a cover (not shown in the figure) disposed on the vehicle 200 and defining a cavity region (not shown in the figure) with the body of the vehicle 200, wherein a first defibrillator module 1 is connected to the cover and located within the cavity region, and the first defibrillator module 1 is exposed from the cavity region when the cover is opened relative to the vehicle 200.
[0053] It is understood that the cover is a rotating or removable cover installed on the vehicle 200. The cover can be a trunk cover, or a cover for the charging port or fuel filler; the specific type is not limited here. The first defibrillator module 1 is connected to the cover and located within the cavity area, making it less likely to be damaged during normal driving of the vehicle 200.
[0054] In some embodiments, the vehicle 200 further includes a charging port (not shown in the figures), and the cover includes a charging cover 202, which is rotatably disposed on the vehicle 200 to cover or expose the charging port. A first defibrillator module 1 is disposed on the charging cover 202 and located on the side of the charging cover 202 near the charging port.
[0055] Thus, the first defibrillator module 1 is positioned at the charging cover 202, near the charging port. When not in use, the charging cover 202 can be fastened to the charging port, resulting in a streamlined overall appearance for the vehicle 200 without any unnecessary structures. When needed, the charging cover 202 can be opened, and a portion of the first defibrillator module 1 can be removed to perform defibrillation on the patient.
[0056] In this embodiment, the location of the first defibrillator module 1 is not limited to meet different needs. Furthermore, the specific form of the control module 3 is not limited to meet different needs. For example, the control module 3 can be an in-vehicle intelligent system.
[0057] In addition, the charging cover 202 uses high-strength materials (such as ABS plastic or aluminum alloy) and has waterproof, dustproof and impact-resistant capabilities to ensure the safe storage of electrodes in complex environments.
[0058] In some embodiments, the vehicle 200 further includes a battery module 203, and the control module 3 further controls the battery module 203 to supply power to the first defibrillator module 1.
[0059] In this embodiment, the specific type of battery module 203 is not limited to meet different needs. For example, battery module 203 can be the battery pack of vehicle 200 to ensure the power supply voltage for the first defibrillator module 1 and the second defibrillator module 2. Of course, battery module 203 can also be a separate battery to power the first defibrillator module 1 and the second defibrillator module 2.
[0060] In some embodiments, the vehicle 200 may further include a switch assembly, which can be connected to the control module 3. The user can control the activation of the first defibrillation module 1 and the second defibrillation module 2 via the switch assembly. In this embodiment, the switch assembly can be a virtual button on the central control screen of the vehicle 200, or a physical button located at any position on the vehicle 200; no specific limitation is made here.
[0061] In some embodiments, the first defibrillation module 1 includes a first electrode plate 11 and a second electrode plate 12, and the control module 3 also controls the battery module 203 to supply power to the first electrode plate 11 and the second electrode plate 12.
[0062] In some embodiments, the first defibrillation module 1 further includes a first electrical connection structure 13 and a second electrical connection structure 14. The first electrical connection structure 13 connects the control module 3 and the first electrode 11, and the second electrical connection structure 14 connects the control module 3 and the second electrode 12. The first electrical connection structure 13 and the second electrical connection structure 14 are deformable, so that the first electrode 11 and the second electrode 12 can move away from the control module 3.
[0063] In some embodiments, the first electrode plate 11 and the second electrode plate 12 are detachably connected to the charging cover 202.
[0064] Specifically, when needed, the first electrode pad 11 and the second electrode pad 12 can be removed from the charging cover 202 and placed on the patient's predetermined position. Then, a defibrillation command is sent to the control module 3. At this time, the control module 3 can supply power from the battery module 203 via the first electrode pad 11 and the second electrode pad 12 in a specific mode, thereby achieving defibrillation. In this embodiment, the first electrode pad 11 and the second electrode pad 12 can be detached from the charging cover 202, and the first electrical connection structure 13 and the second electrical connection structure 14 are deformable, increasing the flexibility of the first electrode pad 11 and the second electrode pad 12, allowing them to extend to positions around the vehicle 200.
[0065] In some embodiments, the first electrical connection structure 13 and the second electrical connection structure 14 are both flexible structures, and both the first electrical connection structure 13 and the second electrical connection structure 14 are formed with telescopic sections. The first electrode sheet 11 and the second electrode sheet 12 extend away from the control module 3 by stretching the telescopic sections.
[0066] Thus, both the first electrical connection structure 13 and the second electrical connection structure 14 are flexible structures and both have telescopic sections. Users can detach the first electrode plate 11 and the second electrode plate 12 and pull the first electrode plate 11 and the second electrode plate 12 to extend the telescopic section away from the vehicle 200, further improving flexibility.
[0067] Specifically, in this application embodiment, the specific form of the telescopic segment is not limited to meet different needs. For example, the telescopic segment can be a coil segment formed by rotating and winding a telephone line, or it can be an elastic, stretchable line segment. Of course, in other embodiments, both the first electrical connection structure 13 and the second electrical connection structure 14 are formed with redundant segments, which can ensure that the first electrode plate 11 and the second electrode plate 12 are further away from the vehicle 200.
[0068] In some embodiments, the first defibrillator module 1 further includes an ejection mechanism 15, which is connected between the charging cover 202 and the first electrode plate 11, and between the charging cover 202 and the second electrode plate 12.
[0069] Thus, the external electrode pads adopt a pop-out design, allowing emergency personnel to quickly access the electrodes and improving rescue efficiency.
[0070] In some embodiments, the pop-out mechanism 15 is a spring or a pneumatic device.
[0071] Specifically, in this embodiment, the pop-out mechanism 15 can pop out the first electrode plate 11 and the second electrode plate 12 from the charging cover 202 to facilitate user disassembly and use.
[0072] In some embodiments, the defibrillation system 100 further includes a monitoring module 4 connected to the control module 3, the monitoring module 4 being used to monitor the time-domain information of the heartbeat and breathing of people around the vehicle 200.
[0073] In this way, abnormal patients can be identified by observing the time intervals between the heartbeats and breathing of those around them, ensuring that patients can receive emergency treatment immediately.
[0074] In some embodiments, the monitoring module 4 and the radar module of the vehicle 200 have the same structure.
[0075] In this way, the radar module of vehicle 200 can monitor the status of people in the surrounding area, so that abnormal patients can be detected as soon as possible and emergency treatment can be provided in time.
[0076] In some embodiments, the defibrillation system 100 further includes a second defibrillation module 2 disposed in the passenger compartment 201 of the vehicle 200, and the control module 3 is electrically connected to the second defibrillation module 2 and is capable of controlling the operation of the second defibrillation module 2.
[0077] In some embodiments, the second defibrillation module 2 further includes a third electrode and a fourth electrode (neither shown in the figures), and the control module 3 is electrically connected to the third electrode and the fourth electrode and is capable of controlling the operation of the third electrode and the fourth electrode.
[0078] In some embodiments, the third electrode plate is disposed on the seat in the passenger compartment 201, and the fourth electrode plate is disposed on the seat belt corresponding to the seat.
[0079] In some embodiments, the second defibrillation module 2 further includes an in-vehicle camera (not shown in the figure), which is connected to the control module 3. The control module 3 determines whether the occupants in the seat are wearing seat belts based on the image information captured by the in-vehicle camera, and controls the third and fourth electrode plates to stop operating when the occupants are not wearing seat belts.
[0080] In some embodiments, the second defibrillation module 2 further includes a piezoelectric sensor integrated on the third and fourth electrode plates and connected to the control module 3. The piezoelectric sensor is used to locate the heart position of the occupant on the third and fourth electrode plates.
[0081] Specifically, the second defibrillator module 2 is an in-vehicle monitoring module capable of monitoring the user's health over extended periods. It utilizes a piezoelectric sensor to monitor heart rate in real time and determines the heart's location through signal amplitude, ensuring high-precision monitoring. The fourth electrode pad is integrated into the seatbelt, maintaining close contact with other electrode modules when the occupant fastens their seatbelt, enhancing monitoring reliability.
[0082] For example, both the third and fourth electrode pads utilize integrated piezoelectric sensors to monitor heart rate in real time and lock the heart's position based on signal amplitude. The third electrode pad is positioned on the seat back of the vehicle's 200 seat, confirming the precise location of the heart through real-time piezoelectric signal analysis. The fourth electrode pad is integrated into the seatbelt, ensuring close contact with both the third and fourth electrode pads when the occupant sits down and fastens the seatbelt. The seatbelt monitoring module analyzes whether the user has fastened the seatbelt using an onboard camera and outputs the information to the onboard intelligent control system to switch the discharge circuit.
[0083] In some embodiments, the second defibrillation module 2 further includes a fifth electrode pad, a sixth electrode pad, and a seventh electrode pad (none of which are shown in the figures), all of which are movably disposed within the crew compartment 201.
[0084] In some embodiments, the control module 3 also controls the battery module 203 of the vehicle 200 to supply power to the fifth electrode plate, the sixth electrode plate and the seventh electrode plate.
[0085] In some embodiments, the defibrillation system 100 further includes an analog-to-digital converter 5 (ADC), which is connected to the control module 3 and is used to convert analog signals into digital signals and transmit them to the control module 3.
[0086] In some embodiments, the control module 3 supplies power to the first defibrillator module 1 and the second defibrillator module 2 through the battery module 203 of the vehicle 200, and can control the high-voltage charging circuit of the voltage output to quickly charge the capacitor to a preset voltage.
[0087] In some embodiments, the defibrillation system 100 further includes a guide groove and a locking structure (not shown in the figures), the guide groove being used to guide the electrode pads of the first defibrillation module 1 and the second defibrillation module 2, and the locking structure being used to lock the electrode pads of the first defibrillation module 1 and the second defibrillation module 2.
[0088] Specifically, the fifth, sixth, and seventh electrode pads are designed as movable electrode modules, connected to the control module 3 via a wired connection. When needed, the fifth, sixth, and seventh electrode pads can be placed on the left and right shoulders and the heart area. This flexibility ensures a rapid response in emergency situations.
[0089] Furthermore, control module 3 is connected to the cardiac acquisition device and high-voltage discharge circuit. It receives defibrillation signals, generates defibrillation commands, and sends them to the cardiac defibrillator. The defibrillation module connects to the ECG signal acquisition circuit via the analog-to-digital converter 5 interface of the vehicle's intelligent system, utilizing the I2C bus to complete timing control and data read / write operations with the transthoracic impedance detection. The electrical defibrillation section first accumulates electrical energy by using the timer function of control module 3 to output PWM for high-voltage charging of the capacitor. The high-voltage detection circuit monitors the voltage across the capacitor in real time and adjusts the PWM duty cycle to charge the capacitor to the preset voltage.
[0090] Example 1: Design and function of the first defibrillation module.
[0091] The first defibrillator module 1 is integrated into the external charging cover 202 of the vehicle 200. The charging cover 202 can be rotatably used to cover or expose the charging port. This allows the first electrode pad 11 and the second electrode pad 12 to be quickly ejected and accessed via a spring or other pneumatic ejection mechanism 15, improving emergency response efficiency. Furthermore, the first electrical connection structure 13 and the second electrical connection structure 14 are flexible and redundant structures, supporting the electrode pads to be extended to different positions in emergency situations, adapting to various emergency scenarios.
[0092] Example 2: Design and function of the second defibrillation module.
[0093] The second defibrillator module 2 is installed in the passenger compartment 201 of the vehicle 200. The third electrode pad is installed on the seat back, and the fourth electrode pad is integrated into the seat belt, fitting against the occupant's chest for efficient defibrillation. An integrated piezoelectric sensor is used to monitor the occupant's heart rate and heart position in real time. The control module 3 determines whether to perform defibrillation based on the detection results.
[0094] Example 3: Functions of the monitoring module.
[0095] Monitoring module 4 and vehicle 200 radar module can share the same hardware structure. They can detect the heartbeat and breathing signals of people in the surrounding area through millimeter-wave radar technology, accurately identify abnormal heart rate, and automatically trigger emergency response.
[0096] Example 4: Power supply and system integration.
[0097] The control module 3 is powered by the vehicle's battery module 203 and supports rapid energy storage via a high-voltage charging circuit, ensuring a rapid response from the first defibrillator module 1 and the second defibrillator module 2 in emergencies. Furthermore, the defibrillation energy is set to 120J, 150J, and 200J for adults, and 50J, 70J, and 85J for children. The control module 3 automatically adjusts the discharge voltage and timing to achieve biphasic defibrillation.
[0098] In some embodiments, the guide groove and electrode plug have a foolproof structure, ensuring unidirectional insertion through an asymmetrical shape to prevent misalignment by the user. The materials of the guide groove and plug include, but are not limited to, high-strength polycarbonate or nylon PA6, and are not specifically limited herein. High-strength polycarbonate or nylon PA6 plastics possess wear resistance and good insulation properties, ensuring safety and reliability.
[0099] In some embodiments, the electrode pads may have a built-in chip that stores electrode pad status information, including usage count, resistance value, and charging status. The built-in chip transmits data via Bluetooth Low Energy 4.2 or NFC, enabling the control module 3 to monitor the health status of the electrode pads in real time and provide alarms for any abnormalities.
[0100] The defibrillation system 100 and vehicle 200 of this application include in-vehicle and out-of-vehicle defibrillation electrode modules and real-time monitoring technology. The in-vehicle module (i.e., the second defibrillation module 2) uses a piezoelectric sensor to monitor heart rate and lock the heart position, while the out-of-vehicle module (i.e., the first defibrillation module 1) has a pop-out design for easy access by emergency personnel. Furthermore, combined with millimeter-wave radar monitoring, the system can accurately detect abnormal heart rates in nearby pedestrians, providing effective support for emergency rescue and improving the safety and emergency response capabilities of the vehicle 200.
[0101] Through the above improvements, the defibrillation system 100 of the present application embodiment also has the following advantages:
[0102] External defibrillation function: Through a pop-up design and flexible connection structure, the first defibrillation module 1 can be quickly deployed to provide efficient defibrillation for people outside the vehicle.
[0103] Real-time in-vehicle monitoring: The second defibrillator module 2 uses a piezoelectric sensor and an onboard camera to accurately detect the occupant's heart rate and seatbelt status, ensuring the accuracy and safety of defibrillation.
[0104] Highly efficient emergency response: Combined with monitoring module 4 (millimeter-wave radar), the system can accurately identify abnormal fall behavior of people outside the vehicle by detecting the movement trajectory, sudden speed changes, attitude height decrease and stationary state of the target outside the vehicle, combined with micro-motion signal detection, and automatically trigger the emergency rescue mechanism to improve rescue efficiency.
[0105] Safe and reliable: The electrode storage compartment is waterproof, dustproof and shockproof, ensuring the safe storage and use of electrodes in complex environments.
[0106] The vehicle-mounted defibrillator system 100 of this invention greatly enhances the flexibility and versatility of emergency medical equipment, especially its ease of use in parking emergency scenarios. The new vehicle-mounted defibrillator system 100 ensures rapid and safe access and use both inside and outside the vehicle, improving the efficiency and effectiveness of emergency response.
[0107] The cardiac activity monitoring module is used to monitor for abnormalities in the occupant's physical condition and, based on these abnormal indicators, analyzes whether the occupant requires defibrillation. If defibrillation is needed, a defibrillation signal is sent.
[0108] The first defibrillator module 1 is installed on the outside of the trunk via a charging cover 202. The electrode storage compartment adopts a pop-out structure; when the charging cover 202 is opened, the electrode pads automatically pop out for immediate access by emergency personnel. The charging cover 202 is made of high-strength ABS plastic or aluminum alloy material, and is waterproof, dustproof, and impact-resistant to protect the electrode pads in various complex environments.
[0109] Furthermore, the first electrode pad 11 and the second electrode pad 12 are automatically deployed via a built-in spring or pneumatic mechanism. The first electrical connection structure 13 and the second electrical connection structure 14 of the first electrode pad 11 and the second electrode pad 12 can be extended to a reasonable length via an automatic telescopic mechanism, ensuring rapid deployment in emergency situations. The first electrode pad 11 and the second electrode pad 12 are made of flexible materials to ensure a close fit to the patient's chest, and the first electrical connection structure 13 and the second electrical connection structure 14 are designed to be extendable to adapt to different emergency scenarios outside the vehicle. The external millimeter-wave radar monitoring module accurately detects the human body's RR interval (the time interval between two heartbeats) based on radar technology, acquiring time-domain information on heartbeat and respiration to determine whether there are abnormal heart rates among nearby pedestrians.
[0110] In this embodiment, the in-vehicle seatbelt defibrillation method is as follows: After the vehicle 200 is powered on, the control module 3 can activate the defibrillation system 100, and the in-vehicle electrode module automatically pops out (it is normally stored in the seat back). The system first performs a self-check, including checking the battery level, defibrillation electrodes, and whether the defibrillation electrodes are in the correct position. If the self-check fails, the in-vehicle voice prompts which item is abnormal, and the self-check continues. If all items in the self-check are normal, the system begins to collect and analyze electrocardiogram (ECG) signals, using a sample-based algorithm to detect ventricular fibrillation. If the result is normal, the ECG signal collection and analysis continue; if the result is abnormal, an emergency call is made and the location information is sent to the backend management, and the defibrillation energy is simultaneously set (120J, 150J, and 200J for adults) to begin charging the capacitor at high voltage. Simultaneously, the onboard control module 3 outputs PWM to control the high-voltage charging circuit for rapid charging, and collects voltage in real time, adjusting the PWM frequency and duty cycle until charging is complete. After charging, a biphasic defibrillation is performed on the patient. After defibrillation, the patient's electrical activity is collected, analyzed, and assessed. If normal, the emergency treatment is considered successful; if abnormal, the defibrillation energy is increased, and defibrillation is continued. After three defibrillation discharges, if the patient's electrical activity remains abnormal, the emergency treatment has failed and is terminated.
[0111] In this embodiment, the charging voltage is calculated as follows: the defibrillation energy of the system for adults is 120J, 150J, and 200J; for children, it is 50J, 70J, and 85J. The biphasic defibrillation time is 6ms for the forward phase and 4ms for the reverse phase. The defibrillation charging voltage is calculated based on the measured transthoracic impedance and the defibrillation energy and discharge time.
[0112] Capacitor discharge formula:
[0113]
[0114] in, R is the initial voltage value of the capacitor, i.e., the charging voltage of the capacitor; R is the resistance of the discharge circuit, i.e., the impedance of the user; C is the capacitance value of the energy storage capacitor. The voltage across the capacitor at time t is the value of the voltage across the capacitor.
[0115] The formula for calculating the energy of a capacitor is:
[0116] CU²
[0117] Let Q represent the defibrillation energy, T be the defibrillation discharge period, and the capacitor charging voltage correspond to the energy it stores. After defibrillation discharge time T, the energy on the capacitor According to the law of conservation of energy, we have:
[0118] - =Q
[0119] Right now
[0120] c- C ²= C( ²- ²)=Q
[0121] According to the capacitor discharge formula, we have:
[0122] [ ²-( )²]= C ²(1- ) =Q
[0123] Export charging voltage:
[0124]
[0125] It should be noted that when performing biphasic defibrillation on a patient, when the electrical energy on the capacitor accumulates to a set value, the on-board intelligent health system controls the relay through the IO port to switch the human body from the physiological signal acquisition circuit to the circuit composed of the discharge circuit. Then, it controls the bridge circuit through the IO port to conduct in the forward direction, generating the first phase current pulse wave, and conduct in the reverse direction, generating the second phase current pulse wave. At this moment, a biphasic defibrillation is completed on the patient. While the two phase current pulse waves flow through the human body, the microcontroller's IO port controls the switching on and off of certain resistors in the digitally controlled resistor bridge to realize the change of internal resistance, so as to maintain the relative constancy of the defibrillation current flowing through the human body.
[0126] like Figure 4 As shown, Figure 4 This is a human-machine interface display design. The vehicle controller completes the initial switching operations of the registers in the LCD via the SPI bus, and then displays the ECG signal, real-time ECG waveform, time, defibrillation status, and some operation indicator images in real time via the data bus. In addition, the vehicle controller connects to the audio codec via SAI (Serial Audio Interface) to transmit clock signals, stuttering clock signals, and voice data, providing voice prompts for defibrillation operations to the patient, and recording the voice situation during the emergency. The WIFI module, as a wireless transmission module, connects to the microcontroller via a USART serial port to access the Internet, allowing doctors to obtain the patient's ECG data during the emergency wirelessly, providing data support for subsequent treatment.
