[0040] The present application will be described in detail below with reference to the accompanying drawings and in conjunction with embodiments. It should be noted that the embodiments in the present application and the features in the embodiments can be combined with each other without conflict.

[0041] In one embodiment, as shown in Figure 1 A flexible wearable multi-physiological parameter monitoring device is provided, including a garment body 1, the garment body 1 including a flexible conductive fiber layer, a sensor hub layer and an elastic protective layer connected in turn, wherein the sensor hub layer is arranged to fit the human body in cooperation with the flexible conductive fiber layer; the sensor hub layer includes a sensor module, a control module and a power module, the sensor module is connected with the control module through a conductive channel arranged in the flexible conductive fiber layer, and the power module is connected with the sensor module and the control module respectively; the sensor module is arranged to fit the human body in cooperation with the flexible conductive fiber layer, for collecting bioelectric signals of the human body and transmitting to the control module, the control module is used for analyzing and processing the bioelectric signals to obtain physiological parameters; the sensors in the sensor module are made of flexible electronic materials, and the sensor module includes a body temperature acquisition module, a blood pressure and blood oxygen acquisition module 3 and an electrocardio acquisition module, wherein the blood pressure and blood oxygen acquisition module 3 is an integrated structure, and uses a photoplethysmography method to simultaneously acquire blood pressure signals and blood oxygen signals.

[0042] The flexible wearable multi-physiological parameter monitoring device provided by the embodiment integrates multiple physiological parameter acquisition modules in the sensor module, realizes comprehensive dynamic monitoring of human health indicators such as body temperature, heart rate, electrocardiogram, blood oxygen saturation and blood pressure, has high integration, and each parameter monitoring independent modular design is convenient to replace or upgrade, has strong flexibility, wherein the blood pressure and blood oxygen acquisition module 3 uses the photoplethysmography method to non-invasively and continuously monitor blood pressure and blood oxygen, further improves the accuracy of physiological parameter reading; the control module processes the bioelectric signal, can effectively filter noise and extract useful physiological information, and improves the accuracy of monitoring result acquisition; the sensor in the sensor module is made of flexible electronic material, which improves the wearing comfort under the premise of ensuring the signal acquisition quality; the garment body 1 is divided into three layers, the flexible conductive fiber layer is attached to the human body to improve the wearing comfort, and the elastic protective layer can make the garment suitable for different outdoor environments, and has strong applicability. The above device has high integration, realizes comprehensive dynamic monitoring of human health indicators, effectively improves the accuracy of physiological parameter reading and monitoring result acquisition, and further improves the wearing comfort, and is suitable for different outdoor environments.

[0043] The elastic protective layer has the characteristics of windproof and rainproof, while maintaining the air permeability. The windproof characteristic can effectively block the cold wind from penetrating the clothes, reduce the loss of human body heat, and keep the user's body temperature stable. The rainproof characteristic can prevent rainwater from penetrating into the inside of the garment, keep the user dry and comfortable, and ensure the safe operation of the sensor and other electronic components is not affected by moisture. The air permeability allows sweat and moisture to evaporate quickly from the skin surface and be discharged through the fabric, helping the body to stay dry. Based on the above characteristics, the device provided by the present application can be used in various weather conditions. Whether it is sunny, rainy or windy weather, it can provide reliable health monitoring and comfortable wearing experience for the user. Even in adverse weather conditions, the protective layer can ensure close contact between the sensor and the skin, reduce external interference, and thus maintain the accuracy of physiological parameter monitoring.

[0044] The sensors in the sensor module are made of flexible electronic materials, including flexible polymer substrates and conductive fibers, which have strong toughness and scalability, can be bent, folded and twisted, while ensuring the wearing comfort and reliable adhesion of the sensor.

[0045] The flexible wearable multi-physiological parameter monitoring device provided by the present application has the specific style as shown in Figure 2 The following embodiments are specifically described and analyzed.

[0046] In one embodiment, the body temperature acquisition module includes multiple flexible temperature sensors 2, which are distributed on the inner surface of the clothing body 1; the flexible temperature sensor 2 includes a first connection structure 201 and a thermal conductive electrode 202, the first connection structure 201 is fixedly connected to the center of the installation side of the thermal conductive electrode 202, the sensing side of the thermal conductive electrode 202 is in contact with the human body, and the installation side of the thermal conductive electrode 202 is detachably connected to the clothing body 1 through the first connection structure 201.

[0047] Among them, the principle of using the body temperature acquisition module to realize body temperature monitoring is as follows: Figure 3 As shown, considering that the skin temperature of different parts of the human body is different, with the head being higher and the feet being lower, the different skin temperatures are determined by the heat flow from the internal temperature of the human body to the skin surface temperature, and the thermal balance between the skin surface temperature and the ambient temperature. Statistics show that the average skin temperature of the human body is 33.8°C. Maintaining a comfortable skin temperature is an important condition for ensuring thermal comfort of the human body. Since temperature measurement is a contact type, there will be a certain temperature difference between the sensor or functional module used for temperature measurement and the skin. Therefore, it is possible to transfer heat by contacting the human skin through the thermal conductive electrode 202. The temperature chip is based on the characteristic relationship between the temperature and the bandgap voltage of the CMOS semiconductor PN junction. After small signal amplification, analog-to-digital conversion, and digital calibration compensation, the digital bus outputs the temperature value.

[0048] Specifically, the structure of the flexible temperature sensor 2 provided in this application is as follows: Figure 4 As shown, considering the comfort of wearing and the convenience of disassembly, the first connecting structure 201 can adopt a button structure. The flexible multi-point temperature sensor specifically adopts a digital sensor solution with an accuracy of ±0.1°C within the temperature range of 0°C-50°C; the flexible temperature sensor 2 belongs to a multi-point contact temperature measurement, and the contact thermal conductive electrode 202 is a stainless steel electrode or a gold-plated copper electrode; Figure 1 As shown, a distributed layout is adopted, and the temperature sensing modules are arranged at six locations on the inner surface of the clothing body 1: the left lower arm, the outside of the left upper arm, the back, the left armpit, the left chest, and the left lower abdomen. They are fixed with buttons to ensure the collection of core body temperature and key upper limb surface temperature.

[0049] In this embodiment, the flexible temperature sensor 2 can provide high-precision temperature measurement, ensuring the accuracy and reliability of the data; the heat-conducting electrode 202 is in direct contact with the human skin, capturing the real body surface temperature through an efficient heat conduction mechanism, reducing the influence of environmental factors on the measurement results; the distributed layout of the flexible temperature sensor 2 can simultaneously monitor the core body temperature and the surface temperature changes of important limb parts, providing more comprehensive body temperature information for the user; the use of flexible temperature sensor 2 and heat-conducting electrode 202 (such as stainless steel or gold-plated copper) not only improves the wearing comfort, but also adapts to the body curve, ensuring good adhesion and reducing the problem of sensor displacement caused by movement; the first connecting structure 201 is in the form of a button, making the sensor module easy to install and detach, facilitating the cleaning of the garment or the replacement of the sensor component, and improving the convenience and flexibility of use.

[0050] In one embodiment, the blood pressure and blood oxygen collection module 3 includes an integrated flexible sensor 301, a flexible packaging protective shell 302, and a second connecting structure 303; the integrated flexible sensor 301 is arranged in the flexible packaging protective shell 302, and the flexible packaging protective shell 302 is detachably connected to the garment body 1 through the second connecting structure 303; the integrated flexible sensor 301 is provided with a shared light emitter 3011, a shared light detector 3012, a light detector 3013, and a light emitter 3014, which constitute a multi-point PPG measurement network, wherein the shared light emitter 3011, the shared light detector 3012, the light detector 3013, and the light emitter 3014 work cooperatively to collect blood pressure signals, and the shared light emitter 3011 and the shared light detector 3012 work cooperatively to collect blood oxygen signals.

[0051] Further, the blood pressure and blood oxygen collection module 3 further includes an interconnection interface 304 and an elastic band 305; the interconnection interface 304 is connected with the integrated flexible sensor 301 and used for connecting external devices; the elastic band 305 is arranged on the side of the garment body 1 away from the integrated flexible sensor 301 and connected with the garment body 1, and used for pressing the flexible packaging protective shell 302 against the human body through elasticity.

[0052] Among them, the principle of realizing blood oxygen monitoring by the blood pressure and blood oxygen collection module 3 of the application is specifically as follows Figure 5As shown, using photoplethysmography (PPG), a certain wavelength of light is incident on the skin from the LED light source (IR & Red LED), after absorption, reflection and scattering of subcutaneous tissue, part of the light can be transmitted from the skin surface and received by the photodetector (PD) inside the chip, in this process, due to the pulsatile change of blood flow volume in subcutaneous tissue with cardiac rhythm, the light intensity received on the photodiode also changes with the pulsatile change, and then the light intensity change signal is converted into an electrical signal, that is, the PPG waveform (PPG signal) of the subcutaneous tissue blood volume change with pulse can be obtained, and the blood oxygen saturation is measured by the light sensor placed at the wrist radial artery using the reflection method, which can be continuously and dynamically monitored.

[0053] As shown in the figure, Figure 6 As shown in the figure, photoplethysmography is a non-invasive detection technology based on photoelectric sensor, which is used to measure the blood flow change on the skin surface, and its basic principle is that when the light of a certain wavelength is irradiated on the skin, the absorption of light by hemoglobin will cause the change of transmitted or reflected light intensity, which is closely related to the change of blood flow volume in blood vessels, so as to indirectly reflect the pulsatile state of blood vessels, and pulse wave transmission time (PTT) refers to the time for the pressure wave emitted by the heart to propagate from the aortic root to other parts of the body. Specifically, PTT measures the time difference between the pulse wave emitted by the heart reaching two different measurement points, so two photoelectric sensors are designed to be located at different positions of the wrist radial artery, and the photodetector reflects the blood volume change caused by the arterial blood pressure fluctuation by detecting the light absorption change on the skin surface, when the two monitoring sites of the wrist radial artery monitor the pressure wave emitted by the heart in turn, the PTT can be obtained by measuring the time difference between the specific feature points in the pulse wave signal, therefore, photoplethysmography can not only realize blood oxygen monitoring, but also can realize the measurement of blood pressure fluctuation and blood flow change.

[0054] Specifically, the blood pressure and oxygen acquisition module 3 provided by the present application has the specific structure as shown in the figure, Figure 7As shown, based on photoplethysmography, two LED light sources, i.e. a common light emitter 3011 and a light emitter 3014, and two photodetectors, i.e. a common light detector 3012 and a light detector 3013, are designed to form a multi-point PPG measurement network, which can comprehensively capture pulse wave signals at different parts such as wrists. The blood oxygen monitoring adopts a single-channel photodetector, which has the characteristics of high-precision measurement, low power consumption, strong anti-interference, and easy integration and multi-channel support, and can provide continuous and non-invasive blood oxygen monitoring without puncture or introduction of external equipment, and is suitable for long-term and daily blood oxygen monitoring. The blood pressure monitoring adopts a double-channel photodetector, which can capture and analyze blood flow signals in blood vessels to realize continuous and non-invasive blood pressure monitoring, which helps to discover blood pressure abnormalities in time and provides important reference data for the prevention and treatment of diseases such as hypertension. The integrated flexible sensor 301 is flexibly packaged by the flexible packaging shell 302, arranged at the wrist radial artery 2-3 cm, and detachable as a whole. The sleeve of the clothing body 1 is fixed by the second connection structure 303, i.e. the button, and then the sensor is attached to the skin surface by the elastic band 305. The interconnection interface 304 can be connected with external equipment for data transmission.

[0055] In this embodiment, the non-invasive continuous monitoring method enables the user to realize continuous blood oxygen and blood pressure monitoring without puncture or other invasive operations, improves the convenience and comfort of use, and is particularly suitable for daily health management and long-term tracking observation. The multi-point PPG measurement network can comprehensively capture pulse wave signals at parts such as wrists, overcome the limitations of single measurement point, and provide more comprehensive physiological information. The integrated flexible sensor 301 is flexibly packaged, which not only adapts to the natural bending of parts such as wrists, but also provides good protection performance and increases the durability of the device. The sensor is fixed on the clothing sleeve by the second connection structure 303 and closely adheres to the skin surface with the help of the elastic band 305, which not only ensures the stability of the sensor but also does not affect the user's freedom of movement, improves the wearing experience, and improves the accuracy of data acquisition.

[0056] In one embodiment, the electrocardio acquisition module includes a plurality of flexible dry electrodes 4 arranged at the wrist of the clothing body 1.

[0057] Wherein, the principle of the ECG acquisition module for ECG monitoring is as follows: there is a special muscle fiber and nerve bundle on the right atrium of the human heart, called the sinoatrial node. The sinoatrial node can automatically and rhythmically generate a series of very coordinated electrical stimulation pulses, which are transmitted in order to the various parts of the heart through the corresponding conduction organization, respectively exciting the atrial and ventricular myocardial cells to produce rhythmic diastole and systole, sending blood to the tissues of the whole body. The sinoatrial node generates an impulse once, and the heart beats once. In medicine, it is called sinus rhythm. The movement of myocardial cells forms a regularly changing potential difference at different parts of the human body, which is called an ECG signal. The ECG signal is collected by the device and depicted in the form of a graph, which is called an ECG (ECG), as shown in Figure 8 The P wave is the first obvious positive wave in the ECG, the Q wave is the first negative wave of the QRS complex, the R wave is the most prominent positive wave in the QRS complex, and the S wave is the last negative wave in the QRS complex. Through the amplitude, shape, time, and other information of the ECG waveform, the working state of the heart can be effectively evaluated. The T wave represents the repolarization process of the ventricle, reflecting the process of the ventricular muscle cells recovering from the excited state to the resting state, i.e., the repolarization of the ventricle. It is usually located after the QRS complex, indicating that the electrical activity of the ventricle gradually recovers to the resting state.

[0058] Specifically, as shown in Figure 9 The ECG acquisition module specifically adopts flexible dry electrodes 4, such as silver fiber foam composite electrodes, silver fiber three-dimensional electrodes, and film electrodes, etc. The silver fiber foam composite electrode has a certain thickness and softness, can be stably attached to the skin, and has stable bioelectric signal acquisition, strong anti-interference ability, and is easy to integrate into medical devices. The ECG monitoring is a single-lead mode, which can arrange multiple flexible dry electrodes 4 at the left and right wrists to achieve effective integration with clothing.

[0059] In this embodiment, the flexible dry electrode 4 has good conductivity and shielding performance, which can effectively reduce the influence of external electromagnetic interference and other environmental noise on the signal, thereby improving the purity and reliability of the signal. The design of the flexible dry electrode 4 can adapt to the body shape and skin curvature of different users, providing a comfortable wearing experience. Compared with traditional wet electrodes, it does not need to use conductive gel, and considering its softness and stability, the user can continuously wear it for a long time, which is suitable for daily health monitoring and long-term physiological data collection. The flexible dry electrode 4 such as the silver fiber foam composite electrode is easy to integrate into clothing or other medical devices, simplifying the manufacturing process and helping to achieve a more compact and lightweight design, improving the practicality of the device, and reducing production costs. By reasonably arranging multiple flexible dry electrodes 4, a single-lead mode can obtain sufficient information to monitor the basic state of heart activity.

[0060] In one embodiment, the power module includes at least one low-temperature lithium battery.

[0061] In this embodiment, the application of the device in a low-temperature environment will cause the battery performance to decrease and the endurance to be short. The power module provided by the application specifically adopts a low-temperature lithium battery, has a wide working temperature range (-40℃ to 60℃), is light and portable, has good discharge characteristics, provides stable current output in a low-temperature environment, and has less temperature influence on discharge performance. Compared with a conventional lithium battery, the low-temperature lithium battery has higher energy density, lower self-discharge rate, and excellent low-temperature discharge performance, and can provide stable and long-lasting power support for electronic devices in extremely cold environments. With the endurance guarantee of the low-temperature lithium battery in a low-temperature environment, the device can be applied in a low-temperature environment and has a more extensive application range.

[0062] In one embodiment, the flexible wearable multi-physiological parameter monitoring device further includes a mobile terminal, and the control module further includes a communication module; the control module is in communication connection with the mobile terminal through the communication module, is configured to transmit the physiological parameters to the mobile terminal through the communication module, and is configured to display the physiological parameters through the mobile terminal.

[0063] In this embodiment, the user can view the physiological parameters such as heart rate, blood oxygen saturation, and blood pressure of the user in real time through the mobile terminal. The immediate data access capability enables the user to understand the health condition of the user at any time. When an abnormal physiological parameter is monitored, the device can issue an alarm or warning information through the mobile terminal to remind the user to take corresponding measures. For the prevention of acute health events such as sudden blood pressure fluctuations of a hypertensive patient, the device has a very fast response speed. The communication module can be a Bluetooth communication module.

[0064] In one embodiment, the control module includes a data processing unit and a data calculation unit connected in series; the data processing unit is configured to receive the bioelectric signals transmitted by the sensor module and perform a preprocessing operation on the bioelectric signals, and the preprocessing operation includes at least one of filtering, amplification, and analog-to-digital conversion; and the data calculation unit is configured to analyze and calculate the bioelectric signals based on a preset machine learning algorithm to obtain the physiological parameters.

[0065] Specifically, the data processing unit pre-processes the received bioelectric signals, including filtering, amplification, and analog-to-digital conversion operations, which can effectively remove noise interference, enhance useful signals, and convert analog signals to digital signals for subsequent processing. Through filtering, unnecessary frequency components such as power frequency interference or motion artifacts can be eliminated, thereby improving signal purity. By appropriately amplifying signal strength, weak but important bioelectric signals can be accurately identified in subsequent processing. Analog-to-digital conversion can convert continuous analog signals into discrete digital signals for further analysis by the computer system. The data calculation unit uses pre-set machine learning algorithms to analyze and calculate the pre-processed bioelectric signals to extract meaningful physiological parameters. Machine learning algorithms include heart rate calculation, blood oxygen calculation, and blood pressure trend prediction algorithms, which not only improve the accuracy of measurement results but also discover complex patterns or trends that traditional methods cannot capture.

[0066] In this embodiment, the machine learning algorithm can establish a personalized health model based on the user's long-term data, providing more accurate health assessment and prediction. Through the trained model, abnormal situations can be automatically identified, providing instant feedback or warning information to the user, which helps to detect potential health problems early. The efficient preprocessing and calculation process enables the system to respond quickly and give results, allowing the user to view their health status instantly through a mobile terminal, enhancing the user experience. Considering the needs and environmental conditions of different users, the flexible data processing and calculation architecture can adapt to various application scenarios, such as daily health management and professional medical use.

[0067] In one embodiment, the sensor module includes a data storage module, the input end of the data storage module is connected with the body temperature acquisition module, the blood pressure and blood oxygen acquisition module 3, and the electrocardio acquisition module respectively, and the output end of the data storage module is connected with the control module.

[0068] In this embodiment, the data storage module can cache data obtained from various physiological parameter acquisition modules locally, ensuring data integrity and preventing data loss due to temporary communication failure or external interference. By integrating the data storage module in the sensor module, data can be stored first and then transmitted to the control module or mobile terminal in batches as needed, reducing the demand for real-time transmission bandwidth, reducing communication delay, and improving the overall response speed of the system. At the same time, it also allows users to continue monitoring and collecting physiological parameters without network connection or mobile terminal, and automatically synchronizes to the control module or mobile terminal when the device restores network connection, ensuring data continuity and integrity.
