Claims 4 / 4 Page 5 CN 122296910 A A Portable Physiological Parameter Assessment System Technical Field

[0001] This application relates to the field of health management technology, and particularly to a portable physiological parameter assessment system. Background Art

[0002] Currently, families and communities have become the core scenarios for daily health management. These scenarios not only require physiological parameter monitoring devices to be easy to operate and suitable for non-professional users, but also place a core demand on high portability. They need to meet the needs of families for on-the-go monitoring, and also be suitable for mobile use scenarios such as community health screening and door-to-door health services. However, the current market...Various physiological parameter monitoring devices currently available cannot meet the comprehensive usage requirements of home and community scenarios, have many technical defects, and are unable to support the comprehensive detection needs of multiple body function systems in such scenarios. They also cannot provide users with intuitive overall health indices, making it difficult to achieve a comprehensive assessment of overall health status.

[0003] In daily health monitoring in homes and communities, most of the existing mainstream consumer-grade monitoring devices are isolated products with single functions, such as scales, smart bracelets, electronic blood pressure monitors, and portable blood glucose meters. These devices can only collect and detect single physiological parameters and cannot achieve comprehensive coverage detection of multiple body function systems such as the human circulatory, metabolic, and muscle systems. While such devices are portable and easy to operate, making them suitable for home and community use, the monitoring data from different devices are stored separately in the devices themselves or in their own independent applications. This lack of an effective unified data management and integration mechanism has resulted in serious data fragmentation. Furthermore, each device can only output isolated parameter values, without a unified overall health index output. Even if users manually collect various types of data, it is difficult to extract intuitive overall health assessment results from multi-dimensional parameters, making it impossible to form a comprehensive understanding of their own health status.

[0004] On the other hand, professional-grade medical testing equipment, such as electrocardiographs, body composition analyzers, and professional blood pressure monitors, can achieve high-precision physiological parameter detection. Some devices can cover parameter collection for multiple body function systems, and the collected data has higher reference value, providing professional support for health management in families and communities. However, such devices are generally expensive and have complex operating procedures, requiring high levels of professional knowledge and skills from operators. More importantly, most professional-grade devices are not portable, and suffer from problems such as large size, need for professional auxiliary equipment, and high power supply requirements. They cannot be used in non-professional scenarios such as homes and communities, making it difficult to adapt to the needs of scenarios such as community door-to-door health testing and home-based professional monitoring. Moreover, the test results of such devices are mostly a list of professional data, without outputting an overall health index for the general public. Ordinary users cannot directly understand the overall health meaning behind the data, which creates a significant gap between consumer-grade daily monitoring and professional-grade accurate testing in home and community scenarios. It is impossible to achieve effective connection between the testing of multiple bodily function systems, nor can it provide ordinary users with an easy-to-understand overall health assessment.

[0005] It can be seen that the existing health monitoring devices are difficult to balance the needs of high portability and comprehensive testing, thus making it difficult to adapt to application scenarios such as homes and communities. This has become a key problem restricting the deep implementation of physiological parameter monitoring technology in daily health management in homes and communities.

The detection indicators corresponding to the respiratory system include at least one of the following: vital capacity, peak expiratory / inspiratory flow rate, resting ventilation, respiratory rate, etc.

[0045] The physiological parameter detection device corresponding to the nervous system may include at least one of the following: an electroencephalogram (EEG) signal detection device and a deep sleep detection device. The detection indicators corresponding to the nervous system include at least one of the following: EEG signal rhythm, depth of sleep, etc.Sleep quality (duration / percentage / cycle, etc.), balance of autonomic nervous function, rest and repair state of the central nervous system, etc.

[0046] The physiological parameter detection device corresponding to the musculoskeletal system may include: grip strength detection device and / or body composition scale, etc. The detection indicators corresponding to the musculoskeletal system include at least one of the following: hand muscle strength, total muscle mass / muscle rate, muscle fat ratio, etc.

[0047] The physiological parameter detection device corresponding to the metabolic system may be a body composition scale, and the detection indicators corresponding to the metabolic system include at least one of the following: body fat percentage, muscle mass, body water percentage, bone mass, basal metabolic rate (derived), etc.

[0048] Each physiological parameter detection device is an independent physical detection device, that is, each physiological parameter detection device has an independent power supply unit, signal acquisition unit and data storage unit. It can independently complete the acquisition and local storage of physiological parameters without relying on other devices. It can be used independently of the system it belongs to, or it can establish a communication connection with the central data processing device in its system and cooperate with other components of the system to realize the function of the system.

[0049] The central data processing device C is housed in the portable case A. The central data processing device C is used to collect the detection data from each physiological parameter detection device B and output the user's physical health assessment data.

[0050] The data output device D is housed in the portable case A. The data output device D is electrically connected to the central data processing device. The data output device D includes a local presentation module and / or an external communication module. The local presentation module is used to present the user's physical health assessment data. The external communication module is used to transmit the user's physical health assessment data to an external presentation terminal.

[0051] Multiple physiological parameter detection devices B corresponding to multiple different body function systems are integrated with the central data processing device C and the data output device D in the portable case A, making the portable case A a single integrated portable device.

[0052] The portable physiological parameter assessment system provided in this specification, through the integrated design of the portable case, centrally houses multiple physiological parameter detection devices corresponding to at least three body function systems. This avoids the inconvenience of carrying multiple independent consumer-grade devices and solves the defects of professional-grade devices, such as large size and poor portability. It can flexibly adapt to mobile scenarios such as home monitoring, community health screening, and door-to-door health services, enabling comprehensive detection of multiple body function systems to be carried out in a portable manner in grassroots scenarios, breaking the technical bottleneck that "comprehensive detection and high portability cannot be achieved simultaneously."

[0053] By integrating multi-dimensional detection devices with the portable case and cooperating with the central data processing device to uniformly acquire all detection data, the isolated physiological data that was originally scattered across different devices and independent applications is collected and managed, completely solving the "data silo" problem of traditional consumer-grade devices. This provides complete and coherent data source support for the comprehensive assessment of multiple body function systems, avoiding assessment bias caused by partial data.

[0054] The portable device integrates three core functions: detection, data processing, and result presentation. Users do not need to switch between multiple independent devices or manually collect and organize data. The entire process of "detection-processing-viewing results" can be completed through the integrated system. It not only meets the self-monitoring needs of home users, but also significantly reduces the operational complexity of community health service personnel, improves the efficiency of grassroots health screening and door-to-door services, and promotes the deep implementation of health monitoring technology in home and community scenarios.

[0055] The system retains the advantages of easy operation and high portability of consumer-grade devices, and can achieve professional-level health assessment depth through comprehensive detection of multiple body function systems and professional data processing of central data processing devices. It effectively fills the technical gap between existing consumer-grade and professional-grade monitoring devices, allowing ordinary users to enjoy integrated health monitoring services of "convenient operation + comprehensive detection + professional assessment" in home and community scenarios.

[0056] It should be noted that in the prior art, physiological parameter detection devices, central data processing devices, and data output devices corresponding to multiple different bodily function systems are usually not integrated into a portable case. This is partly because the electromagnetic interference of cross-modal sensors cannot be solved, and partly because the integrated case will inevitably experience an exponential increase in volume and weight, making it difficult to achieve the portability required for home and community scenarios. Specifically: 1. Electromagnetic interference level: The higher the integration, the more exponentially the interference worsens. In the prior art, the electromagnetic interference problem of single-function devices is easy to solve, but when the cross-modal detection device, high-speed data processing device, and high-frequency display output device are concentrated in a closed space of less than 10L, the electromagnetic interference will evolve from a "single interference source" to "multi-source coupled intermodulation interference", and its interference intensity will increase exponentially rather than linearly superimposed. Specifically, 1. Intrinsic intermodulation interference of cross-modal detection devices. The operating frequency range of detection devices for different bodily functions is extremely wide (from DC to hundreds of kHz). When they are integrated in the same small space, signals from different frequency bands will modulate each other to generate new interference frequencies, which happen to fall within the detection frequency band of weak bioelectric signals. For example, after the 50kHz carrier wave of the body composition scale and the 660nm infrared light modulation signal of the pulse oximeter intermodulate, an interference signal will be generated that overlaps with the ECG QRS complex (0.05Hz-100Hz). This intermodulation interference cannot be eliminated by conventional filtering methods and will directly lead to complete distortion of the ECG detection waveform.

[0057] 2. The central processing unit and data output device are themselves strong sources of interference. Existing technologies generally ignore that the high-speed processor (clock frequency above 1GHz) of the central data processing unit and the LCD / OLED display backlight driving circuit of the data output device are themselves extremely strong sources of electromagnetic radiation. When the distance between them and the ECG and EMG modules that collect microvolt-level signals is less than 5cm, theirThe intensity of radiation interference can exceed 100 times that of the bioelectric signal itself. In a portable case with a capacity of less than 10L, it is impossible to leave enough safe distance to isolate these interference sources.

[0058] 3. The irreconcilable contradiction between shielding scheme and portability. To solve the above interference, the only means in the existing technology is to add metal shielding cover, shielding wire and wave absorbing material. However, for each additional layer of shielding, the weight of the case will increase by 15%-20% and the volume will increase by 10%-15%. If it is necessary to shield the three strong interference sources of component scale, processor and display screen at the same time, the weight of the shielding structure itself will exceed 1kg, which will directly cause the device to lose portability. This forms a vicious cycle of "adding shielding → becoming heavier → losing portability; not adding shielding → insufficient accuracy → unusable".

[0059] II. Case volume level: The existing stacked integration scheme has extremely low integration and serious space waste, which will inevitably lead to the case volume being too large and unable to meet the portability requirements. There is a clear industry consensus on the portability of portable health devices in home and community settings. However, the existing "planar stacking" integration method has extremely low space utilization and cannot meet this requirement. The core problems are reflected in three aspects: 1. The stepping area of ​​the body composition scale has an incompressible hard constraint, which directly occupies most of the bottom space of the box. Body composition detection needs to meet the needs of human feet standing. Its effective stepping area has a fixed physical limitation. When adopting the planar stacking solution, the body composition scale alone will occupy most of the bottom space of the box, resulting in no extra space for other detection devices, central hubs and data output devices, and can only increase the volume of the box.

[0060] 2. The independent structure of multiple modules causes serious space redundancy and low integration. In the prior art, each physiological parameter detection device has an independent shell, battery compartment and interface. When these independent devices are simply stacked into the box, the gaps between the devices, the thickness of the shell of each device and the redundant structure of the independent battery will generate a lot of ineffective space, resulting in extremely low box space utilization and a significant increase in overall volume.

[0061] 3. The unreasonable integration method further aggravates the volume expansion. The centralized power supply design and scattered stacking layout of the prior art cannot achieve compact adaptation of each module. It can only accommodate all components by expanding the box volume, which ultimately results in the box volume far exceeding the portability requirements and failing to meet the mobile use scenarios in the home and community.

[0062] In summary, in the prior art, the unsolvable nature of electromagnetic interference and the rigid constraints of volume are intertwined in a vicious cycle, causing any attempt to integrate multiple system detection devices, central data processing devices, and data output devices into a single portable housing to either sacrifice detection accuracy or portability, ultimately failing to simultaneously meet the comprehensive needs of home and community scenarios for "comprehensive detection + high accuracy + high portability."

[0063] The portable physiological parameter assessment system provided in this specification has a receiving slot in the portable case to accommodate multimodal physiological parameter detection devices corresponding to different body function systems. The shape of the receiving slot matches the shape of the corresponding physiological parameter detection device, which can solve the problems of low integration, large space waste, and excessive volume in the prior art. Specifically, 1. It solves the problem of space redundancy caused by independent shells of multiple modules: In the prior art, each detection device is an independent structure (with an independent shell and battery compartment), and simple stacking easily generates a lot of ineffective space; the receiving slot can accurately position and store each detection device without the need to reserve gaps between devices, reduce the space waste caused by independent shells, improve the space utilization of the case, and avoid the expansion of the case volume due to space redundancy.

[0064] 2. It solves the problem of excessive space occupied by planar stacking: In the existing planar stacking scheme, the body composition scale occupies most of the bottom space, and there is no place for other detection devices; the receiving slot can realize the layered / partitioned storage of multiple detection devices (instead of planar stacking), making full use of the internal space of the case, without significantly increasing the case volume to accommodate multiple detection devices, and helping the case meet the portability requirements.

[0065] In some embodiments, the physiological parameter detection device integrated into the portable housing A includes a body composition scale, and at least one of an electroencephalogram (EEG) signal detection device, a heart rate detection device, a grip strength detection device, and a lung function detection device.

[0066] The EEG signal detection device is a sensor detection device that collects EEG bioelectric signals by contacting the human head, and then processes and transmits them to realize EEG signal detection and analysis. The EEG signal detection device may include a support carrier, an EEG sensing component, a signal processing module, a power supply module, etc.

[0067] The heart rate detection device uses a non-invasive photoelectric detection method to realize real-time acquisition, data processing, and wireless transmission of human heart rate, and can be adapted to detection of multiple parts such as the wrist and fingers. The heart rate detection device includes a PPG photoelectric sensing component, a signal processing module, a power supply module, etc.

[0068] The grip strength detection device collects the mechanical signals of human hand gripping through pressure sensing and converts them into precise grip strength values. The grip strength detection device may include a grip structure, a pressure sensing component, a data display module, a power supply module, etc.

[0069] The pulmonary function testing device adopts a non-invasive indirect detection method. It collects related physical signals such as airflow velocity, respiratory pressure, and chest rise and fall amplitude during human respiration through sensing components. After signal analysis and conversion by a built-in algorithm, core pulmonary function indicators such as vital capacity, resting ventilation, respiratory rate, and peak expiratory / inspiratory flow rate are indirectly derived. The pulmonary function testing device includes a support carrier, indirect sensing components (including miniature airflow sensors, thin-film pressure sensors, flexible displacement sensors, etc.), a signal processing and algorithm module, and a power supply module.

[0070] In addition to the above-mentioned detection devices, it may also include physiological parameter detection devices corresponding to the aforementioned bodily functional systems.

[0071] Each physiological parameter detection device is an independent physical detection device, that is, each physiological parameter detection device has an independent power supply unit, signal acquisition unit and data storage unit. It can independently complete the acquisition and local storage of physiological parameters without relying on other devices. It can be used independently without the system it belongs to, or it can establish a communication connection with the central data processing device in its system and work with other components of the system to realize the system's functions. This setting can solve the problem of "multiple detection device integration and electromagnetic compatibility cannot be achieved at the same time" from three dimensions: interference source isolation, interference generation mechanism blocking, shielding cost and portability decoupling. Specifically, it is explained as follows: 1. Eliminate the fatal interference of strong interference sources to weak bioelectric signals from the root.

[0072] In the prior art, the central high-speed processor (1GHz+ clock) and LCD / OLED backlight driving circuit are extremely strong electromagnetic radiation sources. When the distance between them and the ECG, EEG and EMG modules that collect microvolt-level signals is small, the intensity of radiation interference exceeds 100 times that of the bioelectric signal itself and cannot be eliminated by conventional filtering. This setup allows the detection device to operate independently of the enclosure. During detection, it can maintain an arbitrary safe distance from strong interference sources such as the central data processing device and data output device (e.g., display screen), completely isolating strong radiation interference from a physical space. There is no need to reserve an expensive and space-consuming shielding isolation area inside the enclosure, ensuring the original accuracy of bioelectrical signal detection.

[0073] 2. Completely block intrinsic intermodulation interference of cross-modal detection devices.

[0074] In existing integrated solutions, the operating frequency bands of detection devices for different bodily functions vary greatly (DC to hundreds of kHz). When operating simultaneously, they generate multi-source coupled intermodulation interference, generating noise that falls exactly in the bioelectrical detection frequency band (0.05Hz~100Hz) (e.g., the 50kHz carrier wave of the body composition scale and the infrared modulation signal of the pulse oximeter intermodulate, which will completely mask the ECG QRS complex). This setup supports a single-device independent detection mode, allowing only a single detection device to operate at the same time. This mechanism eliminates the mutual modulation of signals in different frequency bands, thereby solving the problem of intermodulation interference that cannot be eliminated by conventional filtering methods.

[0075] 3. Breaking the vicious cycle of "increased weight from shielding → loss of portability".

[0076] To solve the problem of multi-module interference within the enclosure, existing technologies require the addition of multiple layers of metal shielding covers and absorbing materials. Each additional layer of shielding increases the weight of the enclosure by 15%-20% and the volume by 10%-15%, ultimately leading to a loss of portability. This design only requires lightweight single-module shielding for each independent testing device, eliminating the need for a complex multi-module partitioned shielding structure. During testing, the device is detached from the enclosure, eliminating the need for high-strength shielding between the central data processing device and the testing module. The overall amount of shielding material used is reduced by more than 70%, significantly reducing the system weight and volume while ensuring electromagnetic compatibility, thus meeting the portability requirements of home and community scenarios.

[0077] 4. Eliminate conducted coupling interference from the common power supply circuit.

[0078] In existing centralized power supply schemes, all detection devices share the same power supply circuit. The operating currents of different devices will couple with each other through the internal resistance of the power supply, generating conducted interference (e.g., the large current pulse of the body composition scale will generate spike noise on the power line, crosstalking to the EEG detection circuit). This setting adopts an independent power supply unit for the detection devices, completely cutting off the power conduction interference path between the detection devices, reducing the power noise level by more than an order of magnitude, and significantly improving the signal-to-noise ratio of weak signals.

[0079] 5. Avoid wireless communication self-interference during the detection process.

[0080] Existing integrated physiological parameter assessment systems generally adopt a real-time wireless transmission mode for detection data. The wireless radio frequency signal itself will significantly interfere with the detection of microvolt-level bioelectric signals, and when multiple devices transmit in parallel at the same time, it will further aggravate channel congestion and signal crosstalk, seriously reducing the accuracy and reliability of high-precision detection results. This setup, by configuring independent data storage units for each physiological parameter detection device, supports local caching of detection data and batch synchronization mechanisms during non-detection periods: when performing high-precision bioelectrical detection such as EEG and ECG, the device's wireless communication module can be completely shut down, completely eliminating electromagnetic interference from radio frequency signals to the detection process and ensuring an absolutely pure electromagnetic environment during the detection period; after all detection tasks are completed, the complete detection data stored locally is uniformly synchronized to the central data processing device.

[0081] At the same time, this local storage mechanism also has data transmission fault protection capabilities: when the central data processing device experiences communication interruption, signal loss, or transmission abnormalities, all detection data will be completely stored locally on the detection device, and will be automatically retransmitted after communication is restored, effectively avoiding the loss of detection data due to transmission failure and ensuring the integrity and continuity of data acquisition.

[0082] In some embodiments, a first power supply contact is provided on the inner side of each receiving slot, and a second power supply contact is provided on the outer wall surface of each physiological parameter detection device. The inner wall surface of the receiving slot at the first power supply contact and the outer wall surface of the (physiological parameter detection) device at the second power supply contact are adapted to each other, so that when the physiological parameter detection device is placed in the receiving slot, the positions of the first power supply contact and the second power supply contact match and naturally achieve electrical connection. The first power supply contact is electrically connected to the pre-embedded circuit in the portable case A.

[0083] The pre-embedded circuit is hidden inside the shell of the portable case. When the user uses the portable case for normal testing, the pre-embedded circuit cannot be seen. This ensures the neatness of the case appearance and provides good protection for the circuit, avoiding wear and interference caused by exposed circuits.

[0084] The pre-embedded circuit can be flexibly set according to actual structural requirements. It can be on a printed circuit board (PCB).The circuit can also be a flexible wire. Both forms can achieve a stable electrical connection between the first power supply contact and other electrical components in the box, adapting to different internal layouts and production process requirements of the box.

[0085] The corresponding surface shapes of the first power supply contact and the second power supply contact are matched to form a charging guide groove, which has the following multiple technical effects: 1. Automatic alignment and error prevention: No need for manual precise alignment of the contact position. The user only needs to roughly place the detection device into the receiving groove, and the inclined surface of the guide groove can guide the two contacts to automatically and accurately align and make tight contact, realizing blind plug-in automatic electrical connection, which greatly improves the operation convenience of non-professional users, and avoids the problem of poor contact caused by reverse placement or incorrect placement.

[0086] 2. Ultra-thin, compact and space-saving: This shape-matching surface contact connection method does not require additional complex connection structures such as plugs, sockets, and buckles. The connection thickness can be controlled within 1mm, effectively saving the matching space between the receiving groove and the physiological parameter detection device, further optimizing the internal space utilization of the box, and helping the portable box to achieve miniaturization and lightweight design.

[0087] 3. Reliable contact and long service life: The limiting effect of the guide groove ensures that the contact pressure and contact area of ​​the contact point are consistent each time it is placed, avoiding problems such as excessive contact resistance and heat generation caused by point contact, and improving power supply stability; at the same time, it reduces the lateral friction and wear of the contact point during insertion and removal, significantly extending the service life of the power supply contact.

[0088] 4. Improved protection performance: The shape-adaptive fitting design greatly reduces the gap between the receiving groove and the detection device, effectively blocking dust and moisture from entering the contact area, reducing the risk of contact oxidation and short circuit, and improving the reliability of the equipment in complex usage environments such as homes and communities.

[0089] The above-mentioned first power supply contact and second power supply contact can be magnetic contacts. Using magnetic contacts in combination with a shape-adaptive contact surface can further achieve a thinner connection structure and higher space utilization, eliminating the need for the insertion depth, snap-fit ​​structure and clearance space required by traditional plug-in connectors, making the overall thickness of the contact area thinner, the fit between the housing and the detection device more compact, and further reducing the overall volume and weight. Meanwhile, the magnetic attraction force can assist in the automatic adsorption and alignment of the contacts, further improving the contact reliability based on the guide groove structure, avoiding poor contact due to loosening or displacement, and ensuring stable charging and data transmission.

[0090] In some embodiments, the portable housing A integrates an energy storage battery, which is electrically connected to each of the first power supply contacts inside each receiving slot. This setting has the following technical effects: 1. Significantly reduces the volume and weight of the detection device: Each physiological parameter detection device does not need to have a built-in large-capacity independent battery, which can reduce its volume and weight by 40%-60%, further freeing up the internal storage space of the housing, and fundamentally solving the problem of space redundancy and weight superposition caused by multiple independent batteries. Specification 10 / 21 pages 15 CN122296910 A

[0091] 2. Achieve integrated power supply for on-demand charging: The detection device can be automatically charged when placed in the receiving slot and can be used immediately when taken out. Users do not need to charge or manage the power of each detection device separately, which completely eliminates the pain point of charging multiple devices and greatly improves the convenience of use.

[0092] 3. Further enhance the integrated design: All power supply links are hidden inside the box, with no exposed charging interfaces and cables, which not only ensures the integrity of the appearance, but also avoids the risk of dust and water ingress caused by exposed interfaces.

[0093] Further, in some embodiments, the multiple physiological parameter detection devices integrated in the portable box A include a body composition scale; the battery that powers the body composition scale is used as an energy storage battery and is electrically connected to each of the first power supply contacts inside each receiving slot. This reusable power supply setup has the following technical effects: 1. Reduces the number of batteries from the source, significantly reducing weight and volume: There is no need to set up an additional independent energy storage battery. The large-capacity power supply battery required by the body composition scale itself is reused, directly reducing the volume and weight of a set of batteries and the matching battery compartment, further freeing up the internal space of the box, and helping the system achieve extreme miniaturization and lightweighting.

[0094] 2. Significantly improves battery capacity utilization: The body composition scale is an intermittent working device with short single working time and long standby time, and its battery capacity is idle for a long time. Reusing it as the system's energy storage battery can make full use of the idle battery capacity to power other detection devices, avoiding the waste of battery capacity and extending the total battery life of the entire system.

[0095] 3. Simplifies the circuit structure, reduces costs and failure rate: There is no need to design two independent battery management, charging protection and power supply circuits, which greatly simplifies the electrical wiring and circuit complexity inside the box, reduces production costs, reduces circuit failure points, and improves the overall operational reliability of the system.

[0096] 4. Naturally Matched Power Supply Capacity: The body composition scale requires a large current pulse output during operation. Its matching battery itself has a large current discharge capacity, which can fully meet the charging needs of other low-power physiological parameter detection devices without additional battery specification adjustment, and has excellent adaptability.

[0097] In some embodiments, a second charging interface is provided on the outside of the portable case. The second charging interface is electrically connected to the energy storage battery for charging the energy storage battery.

[0098] In some embodiments, the physiological parameter detection device includes an electroencephalogram (EEG) signal detection device. The EEG signal detection device includes: a first fixing part and a second fixing part for setting detection electrodes. The first fixing part corresponds to the circumference of the head, and the second fixing part corresponds to the midline position of the head.

[0099] The second fixing part is rotatably fixed on the first fixing part. When the EEG signal detection device is housed in the receiving slot, the second fixing part rotates to overlap with the first fixing part.

[0100] Further, in some embodiments, the circumferential length of the first fixing part is adjustable to adapt to differentHead circumference; at least one fixed position on the second fixing part is detachable and adjustable to accommodate different skull heights.

[0101] By rotating the second fixing part to overlap with the first fixing part, the portable head-mounted device can be stored, making its use and storage more convenient and simple; through the storage method of "rotating the second fixing part to overlap with the first fixing part", the lightweight brain function status assessment device can be flat after storage, which can not only greatly improve the utilization rate of storage space, but also effectively compress the storage volume, making it more suitable for daily home storage scenarios (such as drawers, small storage boxes), further enhancing the convenience of the device in daily home use.

[0102] Figure 2 is a three-dimensional structural schematic diagram of the EEG signal detection device provided in this specification, Figure 3 is a top view schematic diagram of the EEG signal detection device provided in this specification, and Figure 4 is a schematic diagram of the EEG signal detection device provided in this specification in a stored state. Wherein, 10 represents the EEG signal detection device, 11 represents the detection electrode, 12 represents the reference electrode, 13 represents the ground electrode, M represents the first fixing part, and N represents the second fixing part.

[0103] The above-mentioned rotatable and stackable EEG signal detection device solves the pain points of existing head-mounted EEG detection devices, such as large storage volume, low integration, easy damage to carry, and cumbersome operation for non-professional users, while taking into account detection accuracy and wearability. Specifically: 1. Extremely compress the storage volume, greatly improving system integration and portability. When stored, the second fixing part can be rotated to completely overlap with the first fixing part, transforming the original T-shaped / cross-shaped three-dimensional structure into a flat and regular planar structure, reducing the storage volume of the device by more than 40%; it can perfectly fit the customized small storage slot in the portable box, without reserving extra clearance space, significantly improving the utilization rate of the internal space of the box, and helping the entire physiological parameter assessment system to achieve miniaturization and lightweight design, meeting the needs of portable scenarios such as community door-to-door service and outdoor mobile testing.

[0104] 2. Simplify the operation process and reduce the threshold for non-professional users. The integrated rotating connection design does not require disassembling any parts. Users only need to rotate with one hand to complete the unfolding and storage of the device, completely avoiding the problems of easy loss of parts and complicated assembly steps of traditional split EEG devices; and after unfolding, the second fixing part naturally corresponds to the midline of the head, realizing the rapid and accurate positioning of the electrodes, without the need for users to manually adjust the electrode arrangement, greatly shortening the test preparation time, and adapting to home self-testing and community batch screening scenarios.

[0105] 3. Improve structural reliability and equipment protection. The second fixing part is permanently rotatably connected to the first fixing part, with no easily lost independent parts, and its structural stability is far superior to that of a detachable design; after being stacked and stored, the originally protruding center electrode is...Completely enclosed for protection, avoiding the risk of electrode bending or damage during transport, while preventing dust and moisture from contaminating the electrode contact surface and extending the device's lifespan.

[0106] 4. Balancing wearability and signal stability. The rotatable second fixing part can be finely adjusted to fit different users' head circumference and head shape, ensuring uniform and stable contact pressure between the midline electrode and the scalp, reducing signal drift and interference caused by improper wearing; combined with adsorption conductive electrodes, it can further improve the accuracy and consistency of EEG signal acquisition.

[0107] 5. Deeply compatible with the integrated system design. The neat shape formed after stacking can precisely fit the inner wall of the receiving slot, ensuring that when the device is placed in the receiving slot, the magnetic power supply contact and data transmission contact automatically and accurately align, realizing blind insertion automatic charging and data synchronization without manual adjustment, perfectly matching the system's integrated design concept of "storage-charging-data transmission". The electrodes set on the EEG signal detection device can be symmetrically distributed in the frontal and central areas of the head, and distributed along the midline in the parietal and occipital lobes. The central data processing device can be configured to perform the operation shown in Figure 5. The operation shown in Figure 5 includes the following steps S110 to S130.

[0108] S110: Acquire multi-channel EEG signals from the prefrontal, central, parietal, and occipital lobes of the brain detected by the EEG signal detection device.

[0109] S120: Determine a four-parameter feature set from the multi-channel EEG signals. The four-parameter feature set includes the following four feature parameters: peak α frequency, 1 / f spectral slope, α wave relative power, and θ wave relative power.

[0110] S130: Calculate a quantitative index value of brain functional state based on a preset mapping relationship according to the four-parameter feature set. Use the quantitative index value of brain functional state as functional system evaluation data of the nervous system. The mapping relationship is determined by training through a sample dataset, and the mapping relationship ensures that when the input four-parameter feature set is the same, a unique quantitative index value of brain functional state is output.

[0111] The quantitative index value of brain function can be reflected as brain age assessment value, brain activation state value, etc.

[0112] The "mapping relationship that outputs a unique quantitative index value of brain functional state when the input four-parameter feature set is the same" mentioned in this application refers to the fact that under ideal technical conditions of no data processing error, the detection equipment being in a standard working environment and rated working state, and no external uncontrollable interference factors, the mapping relationship itself has the uniqueness of the output result. This is the core technical characteristic and design goal of the mapping relationship, and also the key feature of the technical solution protected by this application.

[0113] The four feature parameter set can consist only of the peak α frequency, 1 / f spectral slope, α wave relative power and θ wave relative power. (See page 12 / 21 of the specification, CN 122296910 A)The system consists of four characteristic parameters, and may also include other characteristic parameters on the basis of these four characteristic parameters. These characteristic parameters can be calculated based on the electroencephalogram (EEG) signals detected by the detection electrodes of four brain regions: the prefrontal cortex, central cortex, parietal cortex, and occipital cortex.

[0114] The above four characteristic parameters are approached from three core technical dimensions: rhythm characteristics, power distribution, and network coordination, forming a scientific evaluation system with no redundancy and strong complementarity. This avoids the one-sidedness and limitations of single parameter evaluation, and the evaluation results of each technical dimension accurately correspond to the five core evaluation dimensions of brain functional status defined by the applicant. Specifically, the peak alpha frequency focuses on arousal level and energy state, and is the core rhythmic characteristic indicator reflecting the brain's alertness and basic vitality. The relative power of alpha waves quantifies relaxation state and stress regulation ability, and reflects the balance of rest-activation resource allocation in the brain through power ratio. It is the core power distribution indicator for assessing stress regulation and rest quality. The relative power of theta waves assesses cognitive load and attention concentration ability, memory processing and cognitive reserve ability. It reflects the load intensity and memory processing activity of the brain during task processing through power ratio. It is the core power distribution indicator suitable for all age groups. The slope of the 1 / f spectrum describes the stability of neural rhythm and network coordination, accurately reflects the complexity of the whole brain neuronal network coordination and the basic health status of brain development and aging. It is the core network coordination indicator for monitoring long-term brain health.

[0115] The combination of these four characteristic parameters can completely cover the brain's full-chain function from "basic health → dynamic state → task processing". It can assess real-time state (such as whether you are focused or tired at the moment) and monitor long-term health trends (such as cognitive decline risk and developmental maturity), achieving "three-dimensional assessment" rather than "single-point judgment". It solves the core pain points of existing technologies and achieves a balance between professionalism and practicality.

[0116] The combination of the above four feature parameters follows the principle of necessity and sufficiency and can meet the needs of portable home use.

[0117] By using the combination of four feature parameters to evaluate the brain functional state, it has the following advantages: 1. High computational efficiency: No need for complex nonlinear feature extraction (such as multi-scale entropy, higher-order statistics), it can be calculated only by FFT, linear regression, and power integral, with low requirements for device computing power (consumer-grade microprocessors can support it), and real-time evaluation can be achieved; 2. Low data volume requirement: Only 4-8 channels of data are required, without the need for 16-64 channels of professional-grade equipment to cover the whole brain, reducing the size, weight and cost of the device, and meeting the portability needs of daily monitoring for families and individuals; 3. Avoiding redundant interference: No parameters that are weakly related to brain function (such as absolute power of delta waves, instantaneous amplitude of a single brain region) are introduced, reducing the interference of irrelevant factors on the evaluation results and solving the pain points of "redundant feature parameters and unstable accuracy" in existing technologies.

[0118] The evaluation results using four characteristic parameters can be directly applied to different usage scenarios, satisfying the daily needs of ordinary people.State management can also provide effective reference for health monitoring. Specifically: 1. Daily scenarios: Use α / θ relative power to determine whether it is suitable for work, study, and rest, and use peak α frequency to assess energy status to achieve personalized time management (such as splitting tasks when the θ wave is too high and meditating when the α wave is too low); 2. Health monitoring scenarios: Use the long-term trend of 1 / f spectrum slope to monitor the risk of cognitive decline (such as the slope of the elderly being continuously steep) and the developmental maturity of children (the slope of adolescents gradually flattens); Use the abnormal combination of peak α frequency and θ wave relative power to warn of attention deficit disorder, mild cognitive impairment and other problems; 3. Cross-population adaptation: Applicable to different groups such as children and adolescents (developmental monitoring), adults (work efficiency management), and the elderly (brain health maintenance), without the need to adjust parameter combinations for specific groups, and has strong universality.

[0119] The exclusive quantitative mapping relationship of this application forms a one-to-one closed-loop technical solution with the four-parameter feature set and the 4-8 channel lightweight hardware structure, which is irreplaceable. The core is reflected in the following two aspects: 1. Without this mapping relationship, it is impossible to achieve a balance between lightweight hardware and professional-grade precision.

[0120] If the exclusive quantization mapping relationship of this application is not adopted, there are only two alternative solutions in the prior art, neither of which can be adapted to the core invention purpose of this application.

[0121] The two alternative solutions are: (1) Using a professional-grade full-band multi-parameter complex model: This type of model requires input of more than 10 EEG feature parameters and more than 16 channels of whole brain EEG data, which requires extremely high computing power. The calculation time for a single frame of data is ≥ 4.8 seconds, which cannot be realized on the consumer-grade low computing power microprocessor of this application in real time, and does not meet the lightweight design goal of portable devices at all; (2) Using a conventional simplified linear regression model: Although this type of model can be adapted to low computing power hardware, under the condition of 4-8 channels and four parameters of the small amount of data input in this application, it cannot fit the nonlinear relationship between the four parameters and the brain functional state. The relative error of the evaluation in the home unshielded environment is ≥ 22%, which cannot meet the core requirement of accurate evaluation at all.

[0122] Only the proprietary quantization mapping relationship of this application can achieve an evaluation relative error of ≤5% comparable to that of a professional-grade 64-channel device, while meeting the real-time response requirement of ≤1 second, under the premise of only inputting a four-parameter feature set and adapting to consumer-grade low-computing-power hardware. This is an irreplaceable core technology in the lightweight solution of this application.

[0123] 2. Without this mapping relationship, it is impossible to realize the full-dimensional evaluation value of the four-parameter combination.

[0124] The four-parameter feature set of this application corresponds to the five core evaluation dimensions of brain functional state, and there is a non-linear complementary relationship between the parameters, rather than a simple linear superposition relationship. Conventional general algorithm models cannot make targeted fittings for the dimensional complementary characteristics of the four parameters, either resulting in dimensional redundancy or dimensional missingness, and cannot fully cover the five dimensions.Evaluation dimensions; and the exclusive quantitative mapping relationship of this application is specially trained and optimized based on the complementary characteristics of the four parameters and the correspondence of the five evaluation dimensions. It can accurately fit the nonlinear correlation between the four parameters and the brain functional state, and achieve the core invention purpose of "completing full-dimensional accurate evaluation with the fewest parameters". It forms an inseparable technical whole with the four parameter feature set.

[0125] The detection electrode in the above-mentioned EEG signal detection device can be an adsorption conductive electrode. Figure 6 shows a cross-sectional structural schematic diagram of the adsorption conductive electrode in this embodiment. As shown in Figure 6, the adsorption conductive electrode includes an integrally formed elastic conductive body 25. The elastic conductive body 25 has a skin contact surface 21 and a device contact surface 27 that are arranged opposite to each other.

[0126] In some embodiments, the elastic conductive body 25 can be made of a flexible conductive polymer material, such as conductive silicone, conductive rubber or flexible conductive polyurethane, so that it has good deformation ability and biocompatibility. The elastic conductive body 25 is generally in the form of a sheet or arc shape (which can be adapted to the signal acquisition site, such as an arc-shaped contact structure for the wrist, chest and other parts). In some embodiments, the elastic conductive body 25 can be integrally formed from an elastic matrix and conductive fillers doped in the elastic matrix through injection molding or compression molding. The elastic matrix can be selected from liquid silicone (LSR), thermoplastic polyurethane (TPU) or other polymer materials with good flexibility and resilience (e.g., conductive fabric). Liquid silicone is suitable for skin contact scenarios, with good biocompatibility and high softness. Thermoplastic polyurethane is suitable for collection parts that need to be repeatedly bent, with strong toughness. Conductive fabric is suitable for large-area signal collection, with good breathability. It can be flexibly selected according to actual use needs.

[0127] The conductive filler can be selected from carbon nanotubes, graphene, carbon black or other microparticles or fibrous materials with good conductivity. By uniformly dispersing the conductive filler in the liquid or molten elastic matrix, and then injecting it into the mold for curing, a single, seamless elastic conductive body 25 is formed.

[0128] The device bonding surface 27 is integrally formed with a microstructure adsorption and fixing layer 28. The microstructure adsorption and fixing layer 28 can be formed by directly transferring the microstructure pattern on the surface of the mold cavity during injection molding, or it can be formed on the device bonding surface 27 after molding through processes such as laser etching, micro-imprinting, or chemical etching. In one embodiment, the microstructure adsorption and fixing layer 8 can be a micro-suction cup array, a micro-nano concave-convex structure, or a flexible bonding microstructure. In one embodiment, the microstructure adsorption and fixing layer 28 contains a large number of micron-sized protrusions, pits, or suction cup-like structures.

[0129] The microstructure in the microstructure adsorption and fixing layer 28 can generate adsorption adhesion through physical interactions such as van der Waals forces with the adsorbed surface. The microstructure adsorption and fixing layer 28, through physical adsorption, makes the device bonding surface 27 face-to-face.The contact form is detachably fixed to the surface of the bioelectric signal acquisition device, forming a conductive contact area of ​​the bonding interface. Since it is a physical adsorption, the device surface will not be damaged during disassembly, and it can be reused. Instruction manual 14 / 21 pages 19 CN 122296910 A

[0130] The elastic conductive body 25 has an integrally formed through-type continuous conductive structure 26. The through-type continuous conductive structure 26 can be composed of a continuous network formed by the overlapping of conductive fillers doped in the elastic matrix during the molding process, or it can be formed by embedding conductive fibers, conductive films or metal mesh inside the elastic conductive body 25 in an integrated manner. One end of the through-type continuous conductive structure 26 extends directly to the outer surface of the skin contact surface 21, forming a signal acquisition end exposed to the skin contact surface 21, used to contact the skin of the test object to pick up bioelectric signals. The other end of the through-type continuous conductive structure 26 extends directly to the bonding interface of the microstructure adsorption and fixing layer 28 of the device bonding surface 27, forming a signal output end that is directly connected to the bioelectric signal acquisition device. Since the entire conductive path from the skin contact surface 21 to the device bonding surface 27 is an integrally formed, continuous, and uninterrupted structure, there are no physical interfaces or welding points between different material layers in traditional multi-component electrodes, thus constructing a continuous bioelectric signal transmission path from the skin contact surface 21 to the device bonding surface 27.

[0131] In use, the adsorption conductive electrode of this embodiment presses the microstructure adsorption fixing layer 28 of the device bonding surface 27 against the surface of the bioelectric signal acquisition device (e.g., the metal panel of a fitness equipment handle, the glass surface of a body composition scale, the plastic shell of an ECG patch, etc.). Physical adsorption force is generated between the microstructure and the adsorbed surface, so that the module is firmly attached to the device surface, and a tight planar conductive contact is formed at the same time. At this time, the signal acquisition end of the through-type continuous conductive structure 26 is in contact with the skin of the test object, and the signal output end and the device signal input end are electrically connected through the conductive contact area of ​​the bonding interface. The bioelectric signal is directly transmitted from the skin to the bioelectric signal acquisition device through the through-type continuous conductive structure 26 without the need for additional wires, solder points, or conductive adhesive.

[0132] In the above embodiments, the microstructure adsorption and fixing layer 28 of the conductive module enables the conductive module to be detachably fixed to the original surface of the bioelectric signal acquisition device in a surface contact manner through purely physical adsorption. No installation structure, mechanical interface, or adhesive coating is required on the device, and the device surface is not damaged after disassembly, achieving true plug-and-play and non-destructive assembly / disassembly. The continuous conductive structure 26 extends directly from the outer surface of the skin contact surface 1 to the bonding interface of the device bonding surface 27, eliminating the macroscopic physical interfaces such as fabric / sponge, sponge / wire, and wire / solder joint in traditional multi-component electrodes. This avoids problems such as poor interface contact, resistance drift, and signal loss, ensuring high-fidelity transmission of bioelectric signals from the skin to the acquisition device.The module does not rely on any modifications to the device and can be adapted to various native surfaces such as metal, plastic, glass, and composite materials. The same module can be freely transferred and used between different types of fitness equipment, body composition scales, ECG patches, EEG caps, and other devices, significantly reducing the overall cost for equipment manufacturers and end users. The conductive module can be easily disassembled for cleaning or replacement, effectively addressing the risk of cross-infection in shared environments such as gyms and rehabilitation centers.

[0133] In some embodiments, as shown in FIG7, an antibacterial coating 22, an anti-slip texture 23, and / or a hydrophobic layer 24 are provided on the skin contact surface 21. One or more of the following combined treatments are implemented on the skin contact surface 21 that comes into contact with the skin. In one embodiment, an antibacterial coating 22 can be applied to the skin contact surface 21, using silver ion-based, zinc oxide-based, or organic antibacterial materials to inhibit bacterial growth. In another embodiment, an anti-slip texture 23, such as raised dots, mesh patterns, or stripes, can be formed on the skin contact surface 21 to increase friction with the skin and prevent slippage. In yet another embodiment, a hydrophobic layer 24 can be applied to reduce the adhesion of sweat and body fluids, facilitating cleaning and maintaining signal stability. The above treatment can be achieved by coating, blending or molding into a single piece, improving the hygiene and signal acquisition reliability of the adsorption conductive electrode in multi-person shared scenarios.

[0134] Please refer to Figures 8 and 9, which respectively show the structural schematic diagram of the adsorption conductive electrode in the embodiments of this specification and the application scenario diagram of the adsorption conductive electrode. In some embodiments, as shown in Figure 8, the skin contact surface 21 is provided with a conductive microneedle structure array 29, which is electrically connected to the through continuous conductive structure 26 for passing through hair to contact the scalp. As shown in Figure 9, the microneedle structure provided on the skin contact surface 21 of the adsorption conductive electrode can pass through the hair and contact the scalp, effectively avoiding the interference of hair on signal transmission, reducing contact impedance, and thus improving the reliability and accuracy of EEG signal acquisition, solving the problem of weak and unstable signal caused by hair obstruction during EEG detection by traditional adsorption conductive electrodes.

[0135] Specifically, the conductive microneedle structure array 29 is composed of multiple microneedles arranged at a predetermined interval. The shape of the microneedles can be selected from at least one of a square pyramid, a cone, a triangular pyramid, or a frustum. In one embodiment, the tip of the microneedle is rounded to avoid scratching the scalp. In one embodiment, the height of the microneedles ranges from 200 μm to 800 μm, preferably from 300 μm to 500 μm, to ensure sufficient contact area and low contact resistance.

[0136] The conductive microneedle structure array 29 can be integrally formed with the elastic conductive body 25. During manufacturing, an injection molding process can be used, and a microneedle cavity is set in the mold at the position corresponding to the skin contact surface 1, and a conductive composite material (such as liquid silicone doped with...) is then inserted into the cavity.Carbon nanotubes are injected into a mold to integrally form an elastic conductive body 25 and a conductive microneedle structure array 29 on its surface. At this time, the material of the conductive microneedle structure array 29 is the same as that of the elastic conductive body 25, and the conductive filler inside the microneedles and the through-type continuous conductive structure 26 in the elastic conductive body 25 naturally form a continuous conductive network, realizing a low-impedance electrical connection from the tip of the microneedle to the signal output end. Optionally, after injection molding, a microneedle array can also be formed on the skin contact surface 21 by laser etching or chemical etching process, and then a conductive layer (such as silver, gold or titanium nitride) can be deposited on the surface of the microneedles by sputtering, vapor deposition or chemical plating to further reduce the contact impedance.

[0137] In addition, the conductive microneedle structure array 29 can coexist with the antibacterial coating 22, anti-slip texture 23 and hydrophobic layer 24 on the aforementioned skin contact surface 21. For example, after forming the microneedle array, an antibacterial coating 22 and a hydrophobic layer 24 can be applied only in the flat areas between the microneedles using selective spraying or vapor deposition processes, while keeping the microneedle tips exposed to ensure low-impedance contact; or an ultrathin (<1μm) conductive hydrophobic coating can be applied to the entire skin contact surface 21 (including the microneedle surface) to balance hair-penetrating contact with sweat and dirt resistance.

[0138] In some embodiments of this specification, the elastic modulus of the elastic conductive body 25 varies in a gradient along the direction from the skin contact surface 21 to the device bonding surface 27. The elastic modulus of the skin contact surface 21 region is lower than that of the device bonding surface 27 region, so that the skin contact surface 21 conforms to the microstructure of the skin, while the device bonding surface 27 maintains stable surface contact with the surface of the bioelectric signal acquisition device.

[0139] In one embodiment, the elastic modulus of the skin contact surface 21 is set to a Shore A hardness of 10-25 (approximately 0.5-2 MPa). This low-modulus area can fully conform to the micro-texture of the skin, increase the effective contact area, reduce contact resistance, and improve wearing comfort, avoiding local discomfort or indentations caused by prolonged pressure. In one embodiment, the elastic modulus of the device contact surface 27 is set to a Shore A hardness of 40-70 (approximately 5-20 MPa). This high-modulus area can provide rigid support for the microstructure adsorption and fixing layer 28, ensuring that the micro-suction cup or micro-protrusion maintains shape stability during adsorption, thereby achieving greater adsorption adhesion and resisting shear force during use, preventing the module from accidentally falling off.

[0140] In some embodiments, the physiological parameter detection device includes a body composition scale, as shown in Figures 10, 11, and 12. The body composition scale may include: a scale body 31, a display module 32, and a connecting mechanism 33.

[0141] The scale body 31 is provided with a weighing module and a body composition detection module. The scale body 31 serves as the main measuring component, integrating common weighing modules (such as strain gauge sensors) to acquire weight signals, as well as a body composition detection module (e.g., based on bioelectricity).The circuit based on the principle of impedance analysis (BIA) is used to measure the impedance of the human body through electrodes and calculate composition data such as body fat percentage and muscle mass.

[0142] The scale body 31 has a detection surface, on which detection electrodes are set, which can be the above-mentioned adsorption conductive electrodes. When the user's feet are placed on the detection electrodes, the detection electrodes contact the skin of the soles of the feet and release a weak and safe current to the human body. The body composition is analyzed by detecting the conduction resistance of the current in the body.

[0143] The display module 32 includes a display screen and a wireless communication unit. Specifically, the display module 32 is a module that integrates information presentation and communication functions. The display screen (such as an LCD or OLED screen) of the display module 32 is used to visualize data. The display module specification 16 / 21 pages 21 CN 122296910 A 32 also integrates at least one wireless communication unit (e.g., a Bluetooth module or a WiFi module) for establishing a wireless data link.

[0144] The connection mechanism 33 has a first state and a second state. In the first state, the connecting mechanism 33 keeps the display module 32 mechanically connected to the scale body 31 and allows the display module 32 to rotate relative to the scale body 31 and hover within the rotation range. In the second state, the connecting mechanism 33 allows the display module 32 to be mechanically separated from the scale body 31. The connecting mechanism 33 is used to rotatably connect the display module 32 to the scale body 31. The preset angle range can refer to the angle between the display module 32 and the scale body 31. For example, the preset angle range can be an interval from close to 0° to a certain maximum angle. For another example, the preset angle range can be 0° to 180°. For yet another example, the preset angle range can be 0° to 170°. The connecting mechanism 33 integrates a damping or locking mechanism (such as a friction damper, ratchet mechanism, etc.) so that the display module 32 can be stably held at at least a few specific angles within the preset angle range without continuous hand-holding, making it convenient for the user to view.

[0145] When the display module 32 is mechanically separated from the scale body 31, the display module 32 establishes a communication connection with the scale body 31 through a wireless communication unit. In one embodiment, when the display module 32 is mechanically separated from the scale body 31, its built-in wireless communication unit is activated, and a wireless communication connection (e.g., Bluetooth pairing connection) is automatically established with the corresponding communication unit inside the scale body 31. Through this wireless communication link, the scale body 31 can send real-time detected or stored body composition data to the separated display module 32 for user viewing.

[0146] The above-mentioned body composition scale adopts an integrated design with integrated functions, in-situ storage, and flattened form. By using a foldable embedded display module in conjunction with the scale body's adapter groove, the overall thickness in the folded state is reduced by more than 30%. There is no need to reserve a separate storage slot for the display module and other components in the portable case; all components can be stored in their original positions using the scale body's own space.

[0147] In some embodiments, the connection mechanism 33 further includes a contact conductive structure. When the display module 32 is mechanically connected to the scale body 31, the contact conductive structure charges the display module 32, and / or the display module 32 and the scale body 31 establish a wired communication connection through the contact conductive structure. When the display module 32 and the scale body 31 are mechanically separated, the contact conductive structure automatically disconnects. When the display module 32 and the scale body 31 are mechanically connected through the connection mechanism 33, the contact conductive structure automatically establishes an electrical connection. Current flows from the scale body 31 to the power supply unit (such as a battery) of the display module 32 through the contact conductive structure to replenish its power. Data can be transmitted wiredly between the display module 32 and the scale body 31 through the contact conductive structure. When the user operates the connection mechanism 33 to mechanically separate the display module 32 from the scale body 31, the contact conductive structure automatically and physically disconnects the electrical connection. By setting a contact-type conductive structure, charging and / or data communication functions can be integrated into the physical connection action. Users only need to complete the assembly to automatically obtain a continuous power supply and a reliable data channel, which greatly simplifies user operation and improves convenience. At the same time, the automatic disconnection mechanism ensures safety and allows the weighing scale to seamlessly switch to wireless working mode when separated.

[0148] In some embodiments, the wireless communication unit includes a first wireless communication unit and a second wireless communication unit. When the display module 32 is mechanically separated from the scale body 31, the display module 32 establishes a communication connection with the scale body 31 through the first wireless communication unit and also establishes a communication connection with the central data processing device through the second wireless communication unit.

[0149] In some embodiments, the display screen includes a main display screen located on the front of the display module 32 and an auxiliary display screen located on the back. When the display module 32 is folded over the scale body 31 by the connecting mechanism 33, the auxiliary display screen displays the weight information detected by the weighing module.

[0150] The front of the display module 32 refers to the surface of the display module 32 that is disposed opposite to the scale body 31. When the user rotates and folds the display module 32 via the connecting mechanism 33 to cover the scale body 31 (i.e., in the storage or standby state), the main display screen on the front will be obscured from the surface of the scale body 31. At this time, the auxiliary display screen on the back automatically faces outward and becomes visible. This auxiliary display screen is configured to display the baseline weight information detected by the weighing module. According to the instruction manual (pages 17 / 21, CN 122296910 A), this setting enables rapid measurement in the storage state. The user does not need to unfold or separate the display module 32; simply standing on the scale body 31, the user can directly read the real-time weight data through the outward-facing auxiliary screen in the folded state, simplifying the daily high-frequency simple weighing operation process and providing a burden-free and rapid measurement experience.

[0151] In some embodiments, the upper surface of the scale body 31 is provided with a groove adapted to the display module 32. When the display module 32 is folded over the scale body 31, at least a portion of the display module 32 is embedded in the groove.

[0152] When the user rotates and folds the display module 32 over the scale body 31 via the connecting mechanism 33, the groove can accommodate the display module 32, so that at least a portion of the display module 32 (especially the main body containing the display screen) or all of the display module 32 can be embedded in the groove, rather than simply stacked on the surface of the scale body 31. By embedding the display module 32 at least partially into the scale body 31, the overall thickness in the folded state is effectively reduced, making the product appear flatter when stored. The groove structure can also provide circumferential restraint and protection for the embedded display module 32 (especially its screen and edges), reducing the risk of scratches or damage to the display module 32 during movement, storage, or accidental bumps. In the folded state, the display module 32 is restricted by the groove, making it less likely to slide or shift on the surface of the scale body 31, thus improving the overall structural stability of the device.

[0153] In some embodiments, an electrode handle is also provided on the upper surface of the scale body 31. In addition to the measurement area for standing, an electrode handle and a corresponding connecting wire groove are provided on the upper surface of the scale body 31. The electrode handle is a component for the user to hold, and its surface integrates hand electrodes for bioelectrical impedance measurement. When performing body composition measurement, the user can hold this handle, which, together with the foot electrodes (usually integrated in the standing area of ​​the scale surface), forms a complete current loop to obtain more accurate and stable body composition data. The electrode handle provides a more ergonomic grip, improving the comfort of the measurement process and the reliability of electrode contact.

[0154] In some embodiments, the portable case A includes a cover 100 that can be opened and closed relative to each other and a base 200. The body composition scale 210 is embedded in the base. When the cover 100 is opened relative to the base 200, the detection surface of the body composition scale is exposed for user detection.

[0155] Figure 13 is a schematic diagram of the cover 100 and the base 200 in the closed state, and Figure 14 is a schematic diagram of the cover 100 and the base 200 in the open state. The cover 100 and / or the base 200 have receiving grooves on their inner sides. The receiving grooves on the inner side of the cover 100 are adapted to the shape of other physiological parameter detection devices, and the receiving grooves on the inner side of the base 200 are adapted to the shape of the body composition scale 210.

[0156] The cover 100 and the base 200 can be split open. A connecting component 300 is disposed on the first side of the portable housing and is used to connect the cover 100 and the base 200. For example, as shown in Figure 14, the cover 100 and the base 200 are connected by the connecting component 300, and can rotate and unfold to 180° around the pivot of the connecting component 300. The connecting component 300 may also integrate a resistor.The structure ensures a smoother unfolding process for the cover 100 and the base 200. The connecting component 300 can be a hinged structure.

[0157] The portable case provided in this application adopts this embedded structure, which allows the entire portable case to be placed directly on the ground. The user can complete the test by standing on the body composition scale detection surface of the base without having to remove the body composition scale from the case. This setup offers the following technical advantages: 1. More robust structure and higher integration: The body composition scale and base form an integrated structure with significantly higher connection strength than detachable installations. It can stably withstand the load of a standing person, avoiding the problems of loosening and displacement inherent in independent modules. It also eliminates the need for a separate body composition scale's casing, mounting clips, and storage space, transforming the scale itself into a structural component of the enclosure, greatly improving system integration and further reducing the overall size of the enclosure. 2. More convenient operation and higher testing efficiency: It completely eliminates the steps of taking out, placing, and returning the body composition scale. Users can directly perform body composition testing simply by opening the enclosure, completing the operation in one step. This significantly simplifies the usage process, making it particularly suitable for high-frequency, rapid testing scenarios such as community health screenings and home visits by medical personnel.

[0158] A locking assembly may be provided on the second side of the portable case opposite to and / or adjacent to the first side to restrict the cover 100 and the base 200 from rotating about the pivot of the connecting assembly 300 when closed.

[0159] A handle may also be provided on the side of the portable case opposite to the first side to improve the portability of the portable physiological parameter assessment system and make it adaptable to scenarios such as home health management and community health services.

[0160] In some embodiments, the thickness of the cover 100 may be 45 mm and the thickness of the base 200 may be 24-25 mm, that is, the cover 100 and the base 200 may have a thickness difference.

[0161] The receiving groove may be integrally formed with the rigid shell of the cover 100 and the base 200 by injection molding or stamping; or it may be separately fixed by means of snap-fit, adhesive or other methods at the preset mounting position inside the case.

[0162] To better buffer and protect the various physiological parameter detection devices, flexible buffer layers such as silicone or sponge can be laid inside and at the bottom of the receiving tank. The tank of the body composition scale 210 can adopt a double-layer buffer structure; the opening of the tank can be set in an arc shape, and silicone anti-slip and shock-absorbing protrusions can be set at the bottom of the receiving tank; symmetrical elastic locking protrusions can be set on the tank wall to achieve flexible limiting of the physiological parameter detection devices. The tank of the body composition scale 210 provides suspended positioning protection for the detection electrode area, and is equipped with an ultra-thin silicone pad to prevent compression and wear. All protective structures are integrated with the tank body and do not occupy additional space.

[0163] Body composition scale 210 is disposed inside the base 200. When the base 200 and the cover 100 are opened relative to each other, the detection surface of the body composition scale 210 is exposed for user detection. That is, when the base 200 and the cover 100 are opened, the scale body of the body composition scale 210 can be used directly without being removed from the base 200. If accessories are available, the full function of the body composition scale 210 can be used after removing the accessories.

[0164] As shown in FIG15, 101 can be a receiving groove for a heart rate detection device with a depth of 38mm; 102 can be a receiving groove for a deep sleep module integrating EEG signal detection and heart rate detection functions with a depth of 38mm; 103 can be a receiving groove for an EEG signal detection device with a depth of 28mm.

[0165] In some embodiments, the portable physiological parameter assessment system further includes a shielding part 105 disposed on the cover 100, and at least one side of the shielding part 105 is connected to the side of the cover 100. A magnetic fastener 106 can be provided on the shielding part 105 to fix the shielding part 105 to the cover part 100.

[0166] The shielding part 105 has a first structural position and a second structural position. When in the first structural position, the shielding part 105 can cover the receiving groove inside the cover part 100. When in the second structural position, the shielding part 105 avoids the receiving groove inside the cover part 100, thereby exposing the receiving groove.

[0167] FIG16 is a structural schematic diagram of the shielding part 105 in the first structural position. The shielding effect of the shielding part 105 on the receiving groove of the physiological parameter detection device can be understood in conjunction with FIG15 and FIG17. FIG15 is a structural schematic diagram of the shielding part 105 in the second structural position. The dimensions of the shielding part 105 are similar to those of the base part 200 and the cover part 100, as shown in FIG18.

[0168] When the shielding part 105 is in the first structural position, it can make the inner surface of the cover 100 form a complete and unified visual effect. The irregular structure of the shielding groove avoids the exposed receiving groove from damaging the overall appearance of the shell, making the appearance of the device in the closed state more concise and neat, while improving the visual texture, professionalism and user experience of the product. In addition, even if the cover 100 and the base part 200 are separated in this state, the shielding part 105 can effectively block the detection device in the receiving groove inside the cover, preventing the device from falling out of the receiving groove, and playing a protective and anti-detachment role.

[0169] The shielding part 105 is connected to the side of the cover 100 through a hinge shaft, and can rotate around the hinge shaft to switch between the first structural position and the second structural position. As shown in FIG17.

[0170] In some embodiments, the body composition scale 210 has a built-in display screen. The connection method between the display screen and the body composition scale can be referred to the above description. The display screen is set on the side of the body composition scale facing the cover. When the base part 200 and the cover part 100 are closed, please refer to page 19 / 21 of the instruction manual.When 24 CN 122296910 A is in place, a storage space for the adapted display screen is formed between the two, and the display screen can be embedded in the storage space. In the case that the display screen is a foldable display screen, the foldable display screen can be embedded in the storage space when it is in a folded state. Referring to Figures 14 and 15, the recessed part 104 shown in Figure 15 fits into the shape of the display screen in the folded state.

[0171] In some embodiments, the shell, receiving groove, shielding part and other structures of the cover and base can be used to achieve anti-interference of weak bioelectric signals (electroencephalogram, electrocardiogram, electromyogram), central data processing device, wireless communication, external radiation suppression of the display screen, mutual interference isolation when multiple modules coexist, and meet the requirements of medical-grade electromagnetic compatibility without increasing the volume or compromising portability.

[0172] For example, the shell of the portable case (including the shell of the cover and the shell of the base) can be made of conductive composite material (e.g., injection molded using conductive plastic or conductive glass fiber composite material) to form a continuous conductive shell on the surface. When the cover and base are closed, a 360° conductive shielding closed loop is formed, shielding against external electric field interference. This setup achieves electric field shielding and internal radiation suppression without the need for an additional metal shielding cover, preventing interference from central data processing devices, wireless transmission signals, etc., with microvolt-level signals such as EEG and ECG.

[0173] For example, a conductive buffer layer can be provided on the inner wall of the receiving slot, so that each receiving slot forms an independent shielding cavity. Specifically, ultra-thin conductive cloth or conductive sponge can be embedded in the inner wall of the receiving slot and the bottom buffer layer on the inner side of the cover and base, and the ultra-thin conductive cloth or conductive sponge is electrically connected to the conductive shell to form a conductive buffer layer. Each receiving slot forms an independent Faraday cage cavity, so that there is no electromagnetic interference between different physiological parameter detection devices. The tank of the body composition scale 210 adopts a double-layer buffer structure, and a conductive shielding partition is added between the two layers to block the conduction interference of the scale driving signal and electrode excitation signal to other detection devices.

[0174] For example, the body of the body composition scale 210 provides suspended positioning protection for the detection electrode area (i.e., an ultra-thin conductive shielding film is set in the suspended gap to magnetically and electrically isolate the detection electrodes from the main control and power circuit below. When used with an ultra-thin silicone pad, conductive particles are added to the silicone pad, which also has the functions of buffering and grounding shielding. This setting can completely block the crosstalk of the body composition scale BIA excitation signal (tens of kHz) to the low-frequency signals of EEG and ECG.

[0175] For example, the shielding part 105 can adopt a double-sided structure, with at least one side surface provided with a conductive shielding layer. Specifically, when the shielding part 105 is in the first structural position (covering the receiving groove), the side facing the base (outer side) serves as the aesthetic surface, and the side facing the cover (inner side) serves as the conductive shielding layer, which reliably overlaps with the conductive shell of the cover 100, so that when the shielding part 105 is in the first structural position: it forms a complete closed shielding cavity with the conductive shell of the cover 100, which wraps and shields all the internal detection devices.Within the space; blocking external radio frequency interference (2.4G / 5G / WiFi) from mobile phones, base stations, and home appliances; simultaneously suppressing the outward radiation of internal wireless communication to ensure the purity of bioelectric signal acquisition.

[0176] For example, conductive springs are provided in the pivot and damping structure of the connecting component 300 so that the cover 100 and the base 200 maintain conductive connection at any opening angle from 0° to 180°. This setting ensures that the shielding cavity does not break in the open or closed state, and the electromagnetic shielding remains effective.

[0177] For example, conductive rubber pads are added to the locking component and handle installation position so that all gaps in the box are conductively sealed in the closed state, suppressing electromagnetic gap radiation / leakage.

[0178] For example, a conductive shielding layer is provided inside the display screen storage space formed by the closure of the base 200 and the cover 100 to isolate the display screen backlight driver, wireless communication unit, volume composition detection electrode, and other detection devices. This setting can prevent high-frequency interference from the display screen from directly coupling to the detection electrode.

[0179] The above-mentioned electromagnetic shielding setup, by composite conductive shielding material on the existing integrated structure, utilizes the shell, receiving slot, shielding part, and hinge assembly to form a fully enclosed, continuous, and modularly isolated electromagnetic shielding system. Without increasing the volume of the enclosure, without compromising portability, and without altering the original structure, it achieves the following: effectively suppressing the external electromagnetic radiation of the central control, wireless communication, and display screen driver circuits; blocking the interference of external radio frequency signals on weak bioelectrical signals such as EEG, ECG, and EMG; avoiding intermodulation crosstalk between the body composition scale excitation signal and other detection devices; enabling the device to maintain high-precision detection in complex electromagnetic environments such as homes and communities; and eliminating the need for a heavy metal shielding cover, thus overcoming the industry bottleneck that "shielding inevitably increases weight and volume."

[0180] In some embodiments, the central data processing device can acquire the detection data of each physiological parameter detection device that can be housed in the receiving slot via wireless connection.

[0181] In some embodiments, the system further includes: a remote health management platform communicatively connected to the central data processing device, and / or a health management application for a mobile terminal communicatively connected to the remote health management platform and / or the central data processing device to obtain and present the data processing results of the central data processing device.

[0182] In some embodiments, the content presented by the data output device includes radar charts of functional system assessment data for each bodily function system and / or overall physiological health assessment data, which is calculated based on the assessment data of each bodily function system. Figure 19 is a schematic diagram of an interface for presenting assessment results to a user.

[0183] In some embodiments, the central data processing device is configured to perform the operation described in Figure 20. As shown in Figure 20, the operation includes the following steps S210 to S230.

[0184] S210: Acquire the detection data output by the multimodal physiological parameter detection device that establishes a communication connection with the central data processing device; the detection data of each modality of physiological parameter detection device corresponds to at least one body function system.

[0185] S220: Process the detection data output by the multimodal physiological parameter detection device according to the matched target data processing flow to generate functional system evaluation data of at least two body function systems.

[0186] S230: Generate the user's overall physiological health evaluation data based on the at least two functional system evaluation data according to the matched target data processing flow.

[0187] The above-described S210 to S230 address the existing shortcomings in grassroots health monitoring scenarios such as families and communities, where data from multiple independent portable physiological testing devices are stored in a scattered manner, forming data silos. This leads to users being unable to form a comprehensive and systematic understanding of health, and community health services being difficult to carry out accurately. By using a central data processing device to uniformly access the detection data of multimodal independent physiological parameter testing devices, the detection data of multi-source heterogeneous physiological data is collected in a centralized manner, breaking down the data barriers between different devices and platforms. Through a layered processing flow, the multimodal detection data is first converted into specialized assessment data corresponding to different bodily function systems, and then integrated to generate unified overall physiological health assessment data. This realizes the transformation from isolated single indicators to systematic health quantification results, providing users with a comprehensive and intuitive understanding of health, supporting accurate and systematic health management, and providing standardized health assessment basis for grassroots health services, thereby improving the accuracy and efficiency of grassroots health services.
