Description

Technical Field

[0001] This invention relates to the field of cardiac arrest detection technology, and in particular to an automatic detection and emergency response method for cardiac arrest based on superficial temporal artery pulse waves. Background Technology

[0002] While existing smartwatches have fall detection capabilities, they typically require user confirmation or rely on a mobile phone, and cannot send a distress signal if the user loses consciousness. Summary of the Invention

[0003] According to an embodiment of the present invention, an automatic detection and emergency response method for cardiac arrest based on superficial temporal artery pulse waves is provided. The following steps are performed using a bone conduction hearing aid with integrated superficial temporal artery pulse monitoring function: The pulse wave signal of the user's superficial temporal artery is collected in real time at a preset sampling frequency. The collected pulse wave signals are analyzed in real time to determine whether the conditions for cardiac arrest are met. When the conditions for cardiac arrest are met, a high-intensity emergency alert will be issued to the user for 1 second. If the user is aware of the error, they can actively cancel the false alarm. If the user is unaware and does not actively cancel within S1 seconds, the location command will be activated to obtain the user's current precise location and timestamp. At the same time, send a distress message to your emergency contact.

[0004] Furthermore, the pulse wave signal of the user's superficial temporal artery is collected in real time at a preset sampling frequency. Specifically, the pulse wave signal of the user's superficial temporal artery is collected in real time through the pulse sensor module at the front end of the left and right ear hooks of the bone conduction hearing aid, with a sampling frequency of not less than 100Hz.

[0005] Furthermore, the criteria for determining cardiac arrest include any of the following: The pulse wave signal completely disappeared and lasted for more than S2 seconds; Heart rate remains below 20 beats / min for more than 3 seconds; The pulse wave amplitude decays to less than 10% of the normal amplitude and lasts for more than 54 seconds.

[0006] Furthermore, a high-intensity emergency alert tone is emitted to the user for S1 seconds. Specifically, the microprocessor on the bone conduction hearing aid immediately emits a high-intensity emergency alert tone through the left and right bone conduction transducer units for S1 seconds, while the vibration intensity is adjusted to the maximum.

[0007] Furthermore, the specific actions to actively cancel false alarms include touch and voice commands.

[0008] Furthermore, activating the positioning command to obtain the user's current precise location and timestamp specifically involves: automatically activating the GPS / BeiDou positioning module through the microprocessor on the bone conduction hearing aid to obtain the user's current precise location and timestamp.

[0009] Furthermore, sending a distress message to an emergency contact involves: activating the communication channel via the microprocessor on the bone conduction hearing aid to send the distress message; connecting to a mobile app via Bluetooth; and the app automatically dialing the preset emergency contact number, playing a pre-recorded voice message, and sending a text message containing location information.

[0010] Furthermore, the system includes the following steps: after triggering an emergency warning, the system continues to monitor the pulse wave signal and updates the status every 30 seconds. If the pulse wave signal recovers, it automatically sends a notification to cancel the alarm; if the pulse wave signal continues to disappear, it sends a location update every 5 minutes.

[0011] An automatic detection and emergency response method for cardiac arrest based on superficial temporal artery pulse waves according to an embodiment of the present invention has the following beneficial effects: Fully automatic response, no user operation required: When a user experiences cardiac arrest and loses consciousness, the device automatically completes detection, location and distress call without any user intervention, shortening the distress call time from "unable to call for help" to "automatic second-level response".

[0012] Accurate judgment and reduced false alarms: The system adopts a multi-condition comprehensive judgment (signal disappearance, extremely low heart rate, amplitude decay) and combines it with a short-term cancelable window, which ensures both sensitivity and avoids false triggering.

[0013] Dual-channel communication guarantee: It supports both Bluetooth connection to mobile phones and built-in cellular network to ensure that distress messages can be sent under any circumstances, making it especially suitable for elderly people living alone and outdoor enthusiasts.

[0014] Continuous location updates: After a distress call is made, the location is continuously updated to facilitate dynamic tracking by search and rescue personnel and improve the success rate of rescue.

[0015] It should be understood that both the foregoing general description and the following detailed description are exemplary and intended to provide further illustration of the claimed technology. Attached Figure Description

[0020] The preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings, further illustrating the present invention.

[0021] First, combine Figures 1-4 This invention describes an automatic detection and emergency response method for cardiac arrest based on superficial temporal artery pulse waves according to an embodiment of the present invention. This method is used for automatic detection and emergency response of cardiac arrest and has a wide range of applications.

[0022] like Figures 1-4 As shown, an embodiment of the present invention provides an automatic detection and emergency response method for cardiac arrest based on the superficial temporal artery pulse wave. This method is implemented using a bone conduction hearing aid with integrated superficial temporal artery pulse monitoring function. The bone conduction hearing aid includes a left ear-hook body 100, a right ear-hook body 200, and a main control box 400. The front ends of the left ear-hook body 100 and the right ear-hook body 200 are respectively equipped with an integrated bone conduction transducer unit 301 and a pulse sensor module 302. The main control box 400 contains a microprocessor 500, a Bluetooth module 600, and a GPS / BeiDou positioning module 700. When worn, the pulse sensor module 302 on the left ear-hook body 100 and the right ear-hook body 200 is located above and in front of the tragus, conforming to the skin surface of the superficial temporal artery area. The bone conduction hearing aid also has a built-in cellular network.

[0023] The specific steps are as follows: like Figure 1 As shown, in S1, the pulse wave signal of the user's superficial temporal artery is acquired in real time at a preset sampling frequency. Specifically, the pulse sensor module 302 at the front end of the left ear hook body 100 and the right ear hook body 200 of the bone conduction hearing aid acquires the pulse wave signal of the user's superficial temporal artery in real time, with a sampling frequency of not less than 100Hz.

[0024] like Figure 1 As shown, in S2, the acquired pulse wave signal is analyzed in real time to determine whether the conditions for cardiac arrest are met. The conditions for determining cardiac arrest include any of the following: A: The pulse wave signal completely disappears and lasts for more than S2 seconds, where S2 is 10 seconds; B: Heart rate remains below 20 beats / min for more than S3 seconds, where S3 is 10 seconds; C: The pulse wave amplitude decays to less than 10% of the normal amplitude and lasts for more than S4 seconds, where S4 is 15 seconds.

[0025] like Figure 1 As shown, in S3, when the conditions for cardiac arrest are met, a high-intensity emergency alert tone is emitted to the user for S1 seconds, where S1 is 10 seconds. Specifically, the microprocessor 500 on the bone conduction hearing aid immediately emits a high-intensity emergency alert tone through the left and right bone conduction vibrator units 301 for S1 seconds, while the vibration intensity is adjusted to the maximum.

[0026] like Figure 1 As shown, in S4, if the user is aware, they can actively cancel false alarms by using touch-screen voice commands.

[0027] like Figure 1 As shown, in S5, if the user is unaware and does not actively cancel within S1 seconds, the positioning command is activated to obtain the user's current precise location and timestamp. It should be noted that the GPS / BeiDou positioning module 700 is automatically activated by the microprocessor 500 on the bone conduction hearing aid to obtain the user's current precise location and timestamp.

[0028] like Figure 1 As shown, in S6, a distress message is simultaneously sent to emergency contacts. Specifically, the microprocessor 500 on the bone conduction hearing aid activates the communication channel to send the distress message, connects to the mobile app via Bluetooth module 600, and the app automatically dials the preset emergency contact number, plays a pre-recorded voice message, and sends a text message containing location information.

[0029] Furthermore, the present invention provides an automatic detection and emergency response method for cardiac arrest based on superficial temporal artery pulse waves, which includes the following steps: after triggering an emergency warning, the system continues to monitor the pulse wave signal and updates the status every 30 seconds. If the pulse wave signal recovers, a notification to cancel the alarm is automatically sent; if the pulse wave signal continues to disappear, a location update is sent again every 5 minutes.

[0030] Above, refer to Figures 1-4 An automatic detection and emergency response method for cardiac arrest based on the superficial temporal artery pulse wave according to an embodiment of the present invention is described, which has the following beneficial effects: Fully automatic response, no user operation required: When a user experiences cardiac arrest and loses consciousness, the device automatically completes detection, location and distress call without any user intervention, shortening the distress call time from "unable to call for help" to "automatic second-level response".

[0031] Accurate judgment and reduced false alarms: The system adopts a multi-condition comprehensive judgment (signal disappearance, extremely low heart rate, amplitude decay) and combines it with a short-term cancelable window, which ensures both sensitivity and avoids false triggering.

[0032] Dual-channel communication guarantee: It supports both Bluetooth connection to mobile phones and built-in cellular network to ensure that distress messages can be sent under any circumstances, making it especially suitable for elderly people living alone and outdoor enthusiasts.

[0033] Continuous location updates: After a distress call is made, the location is continuously updated to facilitate dynamic tracking by search and rescue personnel and improve the success rate of rescue.
