Description

Technical Field

[0001] This invention relates to the field of smart medical and wearable devices, specifically to an emergency alarm device and alarm method. Background Technology

[0002] With the accelerating aging of society and the rising incidence of sudden illnesses such as cardiovascular diseases, personal emergency alarm devices are playing an increasingly important role in protecting users' lives. These devices are typically designed as wearables, enabling users to send out distress signals promptly when facing health emergencies.

[0003] Existing emergency alarm devices generally employ physiological parameter monitoring mechanisms based on preset fixed thresholds. This mechanism relies on setting universal warning values ​​for one or more physiological indicators (such as heart rate and blood pressure), triggering an alarm when the monitored data exceeds this fixed threshold. However, significant individual differences exist in human physiological characteristics, and the physiological baseline of the same user changes dynamically at different times and under different conditions. Fixed threshold settings cannot accurately reflect the true health status thresholds of different users or the same user at different times, easily leading to false alarms (alarms sounding when the user is not actually in danger) or missed alarms (no alarm sounding when the user is actually in danger), severely affecting the accuracy and reliability of the alarm.

[0004] Meanwhile, existing devices have a rather simplistic response mechanism after triggering an alarm, typically resorting to the highest-level response, such as directly contacting emergency contacts or medical facilities. This one-size-fits-all approach fails to effectively differentiate the severity of the user's actual situation, easily leading to a waste of emergency rescue resources. Frequent false alarms can also reduce user compliance, ultimately diminishing the device's practical value.

[0005] Furthermore, for users who need to carry emergency medications (such as nitroglycerin) with them, existing portable alarm devices generally lack effective measures to protect the storage environment of these medications. Medications exposed to changes in external temperature are susceptible to high or low temperatures, which can reduce their efficacy or even render them ineffective when users truly need emergency medication.

[0006] Therefore, there is an urgent need for an emergency alarm device and method that can overcome the above-mentioned defects, achieve more accurate judgment of emergencies, more intelligent graded response, and effectively ensure the availability of emergency medicines. Summary of the Invention

[0007] To address the shortcomings of existing technologies, this invention provides an emergency alarm device and method, which solves the problems of high false alarm and false alarm rates due to reliance on fixed thresholds, a single response mechanism that cannot match the actual level of emergency, and a lack of effective environmental protection for the storage of emergency medicines.

[0008] To achieve the above objectives, the first aspect of the present invention provides an emergency alarm device, comprising: a wristband, with a housing fixedly connected to both ends of the wristband, a medicine compartment in the middle of the housing, a warning component installed on the top of the housing, a medicine storage component installed in the middle of the housing, a temperature control component in the middle of the housing, a data storage device in the middle of the housing, and a processor electrically connected to the middle of the data storage device. The processor is equipped with an intelligent protection system, which is used to identify the user's biometric characteristics through the warning component and the sensor component, determine the level of danger, and locate and contact emergency contacts. The medicine storage assembly includes a medicine storage box, which is slidably connected to the middle of the medicine compartment. A spring is fixedly connected inside the housing, and an installation block is fixedly connected to the outside of the spring. A track is provided on the top of the installation block, and a locking rod is fixedly connected inside the housing. The locking rod is slidably connected to the middle of the track.

[0009] In one embodiment, the intelligent guardian system includes: A biometric identification module, connected to the sensor assembly, is used to collect and analyze the user's stress response data, microtremor data, and respiratory rate data in real time to form the current biometric characteristics. The baseline data management module is used to store and update users' daily physiological data to form personal baseline data; The hazard assessment module connects the biometric identification module and the baseline data management module, and is used to compare the current biometric features with the personal baseline data and output the hazard level according to a preset assessment algorithm. The response execution module is connected to the hazard determination module. It is used to receive the hazard level, generate corresponding control commands, drive the warning component to perform early warning actions, and drive the communication module to perform location and contact emergency contacts.

[0010] To make the process of determining the level of danger more specific and quantifiable, the danger determination module specifically includes: The difference calculation unit is used to calculate in real time the difference between the stress response data, microtremor data and respiratory rate data contained in the current biometrics and the personal baseline data; The level determination unit is used to compare the difference with multiple preset crisis thresholds. When the difference exceeds the corresponding crisis threshold, the corresponding crisis level is output.

[0011] Specifically, the difference can be calculated using a weighted summation method. Let the collected stress response data be... Microtremor data are Respiratory rate data are The corresponding individual baseline data is First, calculate the normalized deviation of each individual data point: ; Then the total difference It can be calculated using the following formula: ; in, These are the preset weighting coefficients, and The level determination unit will calculate the... Value and preset low-risk threshold and high-risk threshold Comparison ( This allows for the output of the crisis level.

[0012] To achieve tiered response, the response execution module specifically includes: The early warning instruction generation unit is used when the received crisis level is low (e.g., ), generate control commands to drive the warning component to perform vibration or sound prompts; The emergency command generation unit is used to respond to a high-level emergency situation (e.g., The system generates control commands to drive the communication module to perform operations such as locating and contacting emergency contacts. These operations include obtaining the user's current geographical location and sending a request for help containing that geographical location to the emergency contact.

[0013] Preferably, the warning component includes a warning light, which is fixedly connected to the middle of the housing. A circuit board is provided on the top of the housing, and the warning light is fixedly connected to the top of the circuit board. A display screen is provided on the top of the housing, and a battery is fixedly connected to the bottom of the display screen.

[0014] Preferably, the sensor assembly includes a body temperature sensor, which is fixedly connected to the outside of the wristband. A battery is fixedly connected inside the housing. A data storage device is fixedly connected to the top of the battery. A heart rate sensor is fixedly connected to the bottom of the housing. A heart rate storage device is fixedly connected to the top of the heart rate sensor and is fixedly connected inside the housing.

[0015] Preferably, a blood pressure sensor is fixedly connected to the middle of the housing, and a collision sensor and a GPS sensor are fixedly connected to the bottom of the display screen.

[0016] Preferably, the temperature control component includes a Peltier module, which is fixedly connected inside the housing, and a cooling fan is fixedly connected to the top of the Peltier module.

[0017] Preferably, the wristband has a buckle on its outside and multiple holes in the middle of the wristband, and the buckle engages with the holes.

[0018] A second aspect of the present invention provides an emergency alarm method, comprising the following steps: S1: Baseline Data Management: Stores and dynamically updates users' daily physiological data to form personal baseline data; S2: Biometrics Acquisition: The sensor components are used to collect and analyze the user's stress response data, microtremor data, and respiratory rate data in real time to form the current biometrics. S3: Criticality Level Determination: Compare the current biometric characteristics with the individual baseline data, and output the criticality level according to the preset determination algorithm; S4: Tiered Response Execution: When the crisis level is low, a control command is generated to drive the warning component to perform an early warning action; when the crisis level is high, a control command is generated to drive the communication module to perform the operation of locating and contacting emergency contacts.

[0019] This invention provides an emergency alarm device and alarm method. It has the following beneficial effects: 1. This invention establishes an intelligent protection system that utilizes its internal biometric identification module and baseline data management module to compare and analyze real-time collected biometric data with the user's unique personal baseline data. This individualized judgment method, compared to traditional techniques using universally fixed thresholds, significantly reduces false alarms or missed alarms caused by individual physiological differences, thereby improving the accuracy and intelligence of crisis assessment.

[0020] 2. This invention outputs a specific crisis level through a crisis assessment module, and the response execution module takes differentiated measures based on this level. For low-level crises, only the warning component is activated for local alerts, avoiding unnecessary mobilization of emergency resources; for high-level crises, the communication module is directly activated to perform location and contact emergency contacts. This tiered response mechanism makes emergency handling more targeted and efficient, ensuring that the most appropriate rescue actions are taken in critical moments.

[0021] 3. This invention, by incorporating a temperature-regulating component consisting of a Peltier module and a cooling fan within the casing, enables active temperature control of emergency medications within the medicine compartment. This structure solves the technical problem of emergency medications in portable devices deteriorating and becoming ineffective due to changes in external ambient temperature, ensuring that the medications maintain their proper efficacy when needed, thereby effectively improving the user's self-rescue ability and success rate in emergency situations.

[0024] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0025] Please see the appendix Figure 1 -Appendix Figure 6This invention provides an emergency alarm device, including a wristband 1, with a housing 8 fixedly connected to both ends of the wristband 1. A medicine compartment 18 is opened in the middle of the housing 8, a warning component is installed on the top of the housing 8, a medicine storage component is installed in the middle of the housing 8, a constant temperature component is provided in the middle of the housing 8, and a data storage device 13 is provided in the middle of the housing 8. A processor is electrically connected to the middle of the data storage device 13. An intelligent protection system is installed inside the processor, which is used to identify the user's biometrics through the warning component and sensor component, determine the level of danger, and locate and contact emergency contacts. The medicine storage assembly includes a medicine storage box 6, which is slidably connected to the middle of the medicine compartment 18. A spring 24 is fixedly connected inside the housing 8, and a mounting block 14 is fixedly connected to the outside of the spring 24. A track 19 is provided on the top of the mounting block 14. A locking rod 20 is fixedly connected inside the housing 8 and is slidably connected to the middle of the track 19. A buckle 2 is provided on the outside of the wristband 1, and multiple insertion holes 9 are provided in the middle of the wristband 1. The buckle 2 engages with the insertion holes 9.

[0026] Specifically, the buckle 2 and multiple sockets 9 are used to make flexible adjustment of the wearing. The medicine storage box 6 in the middle of the shell 8, with the cooperation of spring 24, mounting block 14, locking rod 20 and track 19, makes it easy to put and take out medicines and store them stably. The constant temperature component ensures that the medicines are kept at a constant temperature. At the same time, the intelligent protection system in the data storage device 13, combined with the warning component and sensor component, identifies the user's biometrics and judges the level of danger. In case of abnormality, the warning component will issue an early warning and locate and contact the emergency contact person. It integrates convenient wearing, reliable medicine management, upgraded safety protection and efficient function integration.

[0027] Please see the appendix Figure 8 and attached Figure 9 The emergency alarm device provided in this embodiment of the invention has an overall system architecture that mainly includes a physical hardware layer and a functional logic layer. The physical hardware layer includes a wristband 1 fixed to the user's wrist and a housing 8, as well as sensor components, warning components, a communication module, and a data storage unit 13 integrated inside or on the surface of the housing 8 or wristband 1. The functional logic layer is mainly implemented by an intelligent protection system running inside the data storage unit 13, which is the core of the emergency alarm method of this invention. The core workflow of the intelligent protection system can be summarized as the following consecutive steps: The first step is baseline establishment. The system, through its baseline data management module, collects and stores the user's daily physiological data over an initial period. This data is then processed by algorithms to form personal baseline data representing the user's individual health status. This baseline data is not static but is dynamically updated based on subsequently collected data.

[0028] The second step is real-time monitoring. The system connects to the sensor components through its biometric identification module to continuously collect the user's physiological signals in real time. Through signal processing and feature extraction technology, it analyzes the user's stress response data, microtremor data, and respiratory rate data. These data together constitute the user's current biometric characteristics.

[0029] The third step is crisis assessment. The system, through its crisis assessment module, quantitatively compares the current biometric data obtained in the second step with the personal baseline data established in the first step. This comparison is achieved by calculating the degree of difference between the two. For example, let the current biometric vector be... The individual baseline data vector is ,in These represent the current values ​​of stress response data, microtremor data, and respiratory rate data, respectively. This represents the corresponding baseline value. Difference It can be calculated using the following formula: ; in, These are preset weighting coefficients used to adjust the importance of different biometric characteristics. Subsequently, the hazard assessment module calculates the degree of difference. It compares the situation with one or more preset crisis thresholds to output a clear crisis level.

[0030] The fourth step is a tiered response. The system receives the severity level output by the hazard assessment module through its response execution module. If the severity level is determined to be low, a control command is generated to drive the warning component to perform an early warning action; if the severity level is determined to be high, another control command is generated to drive the communication module to perform the operation of locating and contacting emergency contacts, thereby completing a complete and intelligent emergency alarm process.

[0031] The baseline data management module is configured to generate and maintain the user's personal baseline data. Upon initial device activation or reset, this module enters an initial baseline establishment cycle, for example, lasting 72 hours. During this period, the module continuously collects various physiological data from the user via sensor components and performs statistical processing on the collected data set, such as calculating its mean or median, to generate the initial personal baseline data. To adapt to long-term changes in the user's physiological state, the module also implements a dynamic update mechanism. Specifically, it incorporates newly collected daily physiological data into the existing baseline using an exponential moving average (EMA) algorithm, with the update formula as follows: ; in, These are the updated baseline data values. These are old baseline data values. These are the corresponding physiological data values ​​that have been collected so far. It is a smoothing factor (e.g., 0.05) used to control the rate of updates.

[0032] The biometric identification module is directly connected to the sensor components, and its function is to convert raw sensor signals into structured current biometrics in real time. Specifically, this module performs the following analyses: For stress response data, it quantifies the data by analyzing heart rate variability (HRV) indicators acquired by the heart rate sensor, such as calculating the standard deviation of continuous heartbeat intervals (SDNN); for microtremor data, it performs a Fast Fourier Transform (FFT) on the signals acquired by the accelerometer and extracts the signal energy within a specific physiological frequency range (e.g., 8-12 Hz) as the quantified value; for respiratory rate data, it calculates the user's real-time respiratory rate by analyzing the baseline drift or changes in thoracic impedance of the photoplethysmography (PPG) signal. These three analytical results together constitute the current biometrics.

[0033] The hazard assessment module is the core of the system's decision-making process. It receives individual baseline data from the baseline data management module and current biometric data from the biometric identification module, and outputs the hazard level. The internal difference calculation unit of this module first performs a quantitative comparison of the input data. It first calculates the normalized deviation of each biometric feature, and then obtains the total difference through weighted summation. The calculation formula is: ; in, Total variance; These are the quantified values ​​of current stress response data, microtremor data, and respiratory rate data. This corresponds to the individual's baseline data value. These are preset weighting coefficients that satisfy... 1.

[0034] Subsequently, the grading unit will calculate the degree of difference. Compared with the preset low-risk threshold and high-risk threshold (in Compare them.

[0035] like If so, output the normal level; if If so, output a low-level crisis level; if If so, a high-level crisis level will be output.

[0036] The response execution module performs the final operation based on the received crisis level. The warning instruction generation unit within this module is configured to generate control instructions to drive warning components to perform local warning actions when a low-level crisis level is received, such as driving a vibration motor to vibrate at a specific frequency or driving a warning light to flash in a specific color. The emergency instruction generation unit within the module is configured to generate and execute a complete set of operations for locating and contacting emergency contacts when a high-level crisis level is received. The control instructions for this operation trigger the communication module, which first activates the GPS sensor to obtain the user's current geographical coordinates, then embeds this coordinate information into a preset-formatted distress message text, and finally sends this information via the cellular network to the contact terminals of one or more emergency contacts pre-stored in data storage 13.

[0037] Please see the appendix Figure 1 -Appendix Figure 4 The warning assembly includes a warning light 5, which is fixedly connected to the middle of the housing 8. A circuit board 10 is located on the top of the housing 8, and the warning light 5 is fixedly connected to the top of the circuit board 10. A display screen 3 is located on the top of the housing 8, and a battery 16 is fixedly connected to the bottom of the display screen 3.

A battery 11 is fixedly connected to the inside of the housing 8, and a data storage device 13 is fixedly connected to the top of the battery 11. A heart rate sensor 7 is fixedly connected to the bottom of the housing 8, and a heart rate storage device 23 is fixedly connected to the top of the heart rate sensor 7. The heart rate storage device 23 is fixedly connected to the inside of the housing 8. A blood pressure sensor 12 is fixedly connected to the middle of the housing 8, and a collision sensor 17 and a GPS sensor 15 are fixedly connected to the bottom of the display screen 3.

[0038] Specifically, batteries 11 and 16 provide power to components inside the housing 8, including the blood pressure sensor 12, data storage device 13, heart rate sensor 7 and heart rate storage device 23, and the top display screen 3, collision sensor 17, and GPS sensor. The sensor components collect physiological data such as body temperature, heart rate, and blood pressure in real time, as well as status and environmental data such as collision and GPS positioning. After classification and storage, the data is analyzed and judged by the circuit board 10. The display screen 3 displays relevant information in real time. When the data is abnormal, the warning lights 5 in the middle of the housing 8 and the top of the circuit board 10 are triggered to flash and provide an early warning. This enables comprehensive health monitoring and safety risk warning, and the information is intuitive, the equipment operates reliably, and it is suitable for various scenarios.

[0039] Please see the appendix Figure 7 The temperature control component includes a Peltier module 21, which is fixedly connected inside the housing 8, and a cooling fan 22 is fixedly connected to the top of the Peltier module 21.

[0040] Specifically, the Peltier module 21 is fixed inside the housing 8. It uses the thermoelectric effect to transfer heat through current to cool or heat the medicine in the medicine compartment to regulate the temperature. The cooling fan 22 on top dissipates excess heat in time to avoid affecting the temperature control effect and ensure that the Peltier module 21 operates stably to maintain a constant temperature in the medicine compartment. This component can accurately regulate the temperature to meet the storage needs of different medicines and prevent medicines from failing due to unsuitable temperature. The cooling fan 22 ensures the efficient and stable operation of the component and provides a reliable storage environment for medicines that require strict temperature control.
