Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of this utility model.
[0027] Example:
[0028] like Figures 1 to 6As shown, a human multimodal physiological signal acquisition device includes a main acquisition unit 1 and a base 9. The base 9 is installed behind the main acquisition unit 1, and the bottom surface of the base 9 is flush with the bottom surface of the main acquisition unit 1. A touch screen 3 is installed on the front panel of the main acquisition unit 1. A camera 4 for face recognition acquisition is built into the top of the touch screen 3. A microphone port 5 is embedded in the bottom of the touch screen 3. A power button 6 is installed on the main acquisition unit 1 below the touch screen 3. A speaker 7 is provided near the top of the rear side of the main acquisition unit 1. A sensor interface 17 is provided on the upper side inside the base 9. A signal transmission line 2 is connected to the sensor interface 17 through a connector 18. Two wires branch off from the end of the signal transmission line 2, and two sets of finger sleeves 19 are connected to them respectively. The two sets of finger sleeves 19 integrate a heart rate sensor, a pulse sensor, a blood oxygen saturation sensor, and a skin temperature and skin conductance sensor. This design solves the problem that existing psychological risk assessment methods mainly rely on interviews and questionnaires by psychologists, which have the problems of strong subjectivity, long measurement time, single measurement form, and outdated norms used, and cannot meet the actual assessment needs. In addition, some patients cannot accurately describe their psychological state and problems, leading to unstable diagnostic results and failing to meet the need for comprehensive and accurate psychological risk assessment.
[0029] This invention integrates multiple physiological sensors, enabling the simultaneous acquisition of various physiological signals, including heart rate, pulse, blood oxygen saturation, skin temperature and skin conductance, voice, and facial expression. It also processes and analyzes the data using advanced algorithms to achieve an accurate assessment of an individual's psychological state.
[0030] In this embodiment, multiple sets of sensor interfaces 17 are provided for extended connection to external ECG and EEG sensors. The design of multiple sensor interfaces 17 allows users to freely select and connect different types of external sensors as needed. This flexibility not only enhances the applicability of the device but also provides users with more diverse data acquisition solutions. By increasing the number of sensor interfaces 17, the device can support a wider variety of external sensors. For example, advanced physiological signal acquisition devices such as ECG and EEG sensors can seamlessly connect to the acquisition host 1 through these interfaces, enabling more comprehensive physiological signal monitoring.
[0031] In this embodiment, the data acquisition host 1 internally includes a main control module, a data acquisition module, a data processing module, a storage module, and a wireless network module. The main control module is the "brain" of the entire data acquisition host 1, responsible for coordinating and controlling the work of each module. It receives user commands, converts the commands into operation signals that each module can understand through internal logic circuits, and ensures that the modules can work together to achieve data acquisition, processing, storage, and transmission. The data acquisition module is responsible for acquiring physiological signals from various sensors such as heart rate sensors, pulse sensors, blood oxygen saturation sensors, skin temperature and skin conductance sensors, and possibly extended electrocardiogram sensors, electroencephalogram sensors, etc. It converts these analog signals into digital signals for subsequent processing and analysis; the data processing module preprocesses and analyzes the collected physiological signals to extract useful physiological information and provide data support for subsequent psychological risk assessment or physiological state monitoring; the storage module stores the collected physiological signal data and the processed analysis results for easy data retrieval later; the wireless network module is responsible for transmitting the collected physiological signal data and analysis results to cloud servers, mobile devices or other receiving devices via wireless networks such as Wi-Fi, realizing remote monitoring and sharing of data, and allowing users to view and analyze data at any time.
[0032] The main control module, data acquisition module, data processing module, storage module, and wireless network module in this embodiment have already been used in existing human body detection instruments and are considered existing technology. They are not innovative features of this utility model and can be obtained by those skilled in the art through commercial means.
[0033] In this embodiment, the data acquisition host 1 has an inwardly recessed slot 8 near the top of the rear side, which makes it easy for users to take it out and carry it.
[0034] In this embodiment, a panel is provided on the rear side of the base 9, on which a communication serial port 10, an OTG interface 11, a USB interface 12, an HDMI interface 13, a gateway interface 14, and a power interface 15 are respectively installed. The communication serial port 10 is used for serial communication with other devices or systems to transmit physiological signal data to a computer, data logger, or other external devices for further data processing, analysis, or storage. Through the OTG interface 11, users can directly connect the acquisition device to other OTG-enabled devices such as smartphones and tablets to achieve real-time data transmission and sharing. The USB interface 12 can be used to connect devices such as printers and external storage devices to expand the functionality of the acquisition device. Through the HDMI interface 13, users can connect the acquisition device to a high-definition display device to display physiological signal data or analysis results in real time, achieving dual-screen display for easy observation and analysis. The gateway interface 14 is used to connect a network cable to achieve remote data transmission and monitoring. Through the gateway interface 14, users can remotely access and control the acquisition device, obtain real-time physiological signal data, and perform remote diagnosis and treatment. The power interface 15 is connected to a power socket or power bank to provide the necessary power support for the acquisition device.
[0035] In this embodiment, a power switch 16 is provided on the right side of the power interface 15. The main function of the power switch 16 is to control the power supply of the acquisition device. When the user needs to start or stop the acquisition of physiological signals, this can be achieved by simply pressing or turning off the power switch 16.
[0036] In this embodiment, the data acquisition host 1 has a built-in power supply, which is connected to the power interface 15 via a charging module. This built-in power supply design allows the data acquisition device to operate in a power-free mode, enabling it to work independently for a period of time without an external power source, greatly enhancing the device's portability and flexibility.
[0037] In this embodiment, the finger sleeve 19 is made of elastic band and has a closed ring structure. The elastic band has good elasticity and can adapt to different finger sizes and shapes, ensuring that the finger sleeve 19 can fit snugly on the finger. In addition, the elastic band material is soft and breathable, and will not cause pressure or discomfort to the fingers even after wearing for a long time, thus improving the user experience.
[0038] This device uses an embedded LINUX system, an RK3568 chip, and a 500Hz, 24-bit ADC pulse wave converter. It can automatically generate color graphic print reports, perform report queries and batch printing, support data file export and group statistical analysis functions, and has a built-in ID card recognition module.
[0039] The working principle of this human multimodal physiological signal acquisition device:
[0040] In actual use, ensure the device is fully charged or connected to an external power source.

Wear the finger sleeve 19 on your finger, ensuring the sensor is in close contact with your finger. Press the power button 6 to start the device. Select the acquisition mode or set parameters via the touchscreen 3. The device begins acquiring physiological signal data and displays it on the touchscreen 3 in real time. The device acquires individual physiological signals in real time through integrated multiple physiological sensors such as heart rate sensors, pulse sensors, blood oxygen saturation sensors, skin temperature and skin conductance sensors, and potentially expanded ECG and EEG sensors. The acquired physiological signals are transmitted to the data acquisition module within the acquisition host 1 via the signal transmission line 2. The data acquisition module converts the received analog physiological signals into digital signals and transmits them to the data processing module. The data processing module preprocesses the digital signals, such as filtering, noise reduction, and feature extraction, to obtain useful physiological information. Simultaneously, the device acquires facial information via camera 4 and voice information via microphone; this information is also transmitted to the data processing module for analysis. The processed physiological signal data and analysis results are stored in the storage module for easy retrieval later. The wireless network module is responsible for transmitting real-time data and analysis results to cloud servers, mobile devices, or other receiving devices via wireless networks such as Wi-Fi, enabling remote monitoring and sharing of data.
[0041] In summary, this multimodal physiological signal acquisition device integrates multiple physiological sensors and employs advanced data processing and wireless network transmission technologies to achieve comprehensive and accurate acquisition and analysis of individual physiological signals. Its user-friendly operation and powerful functions make it a promising candidate for applications in psychological assessment, medical diagnosis, and motion monitoring.
