Description

Technical Field

[0001] This invention belongs to the field of biological health diagnosis and treatment equipment technology, specifically relating to an integrated diagnosis and treatment device for measuring human composite parameters and photoelectric therapy. Background Technology

[0002] Bioimpedance is a physical quantity reflecting the electrical properties of biological tissues or the entire organism. Human tissues exhibit different impedance characteristics in different states; therefore, measuring bioimpedance at relevant areas of the human body can serve as a parameter for human health. Impedance measurement and analysis techniques have wide applications in medicine, such as impedance imaging, early breast cancer screening, and body composition analysis. Body temperature is one of the key physiological parameters of human health; high-precision monitoring of skin temperature can serve as an important basis for disease diagnosis. Electrostimulation therapy injects low-frequency current signals into specific areas, effectively stimulating corresponding human tissues to improve abnormal conditions. Infrared light therapy, as an adjunct to electrostimulation, can accelerate blood circulation simultaneously with electrostimulation, resulting in better therapeutic effects.

[0003] Currently, numerous electrotherapy devices are used as adjunctive therapies to improve abnormal conditions in human tissues. For example, patent CN106215316B discloses a mid-frequency therapeutic signal generator, which limits the magnitude of the therapeutic pulse current through a potential adjustment circuit. Patent CN110975139B discloses an eight-channel output mid-frequency electrotherapy device, but the electrostimulation therapy is at fixed levels and lacks monitoring of the therapeutic current. Furthermore, this device is too large and heavy, limiting its application scenarios, and the eight-channel function is merely a simple repetition within a single device. Patent CN103751907B designs a touchscreen-controlled mid-to-low frequency electrotherapy device. This device introduces a therapeutic current monitoring circuit, but it only provides simple monitoring and protection functions without closed-loop control. The touchscreen merely replaces the control functions of traditional mechanical buttons, failing to fully utilize its modern human-computer interaction advantages. Patent CN110833656B discloses a constant current output intermediate frequency therapeutic instrument system. This device uses a maximum output therapeutic current as a protection mechanism and a very large electrode detachment resistance as a means of detecting treatment circuit breaks. Patent CN104623802B discloses an electrotherapy waveform generation device. This device determines whether the electrode has detached by identifying the magnitude of the therapeutic voltage and calculates the current flowing through the human body by analyzing the therapeutic waveform current. However, both of these solutions can only determine extreme cases, relying solely on a detachment detection value set by the instrument itself. They do not consider the actual human body impedance during use, and the therapeutic current is merely a simple monitoring and alarm function to remind the user to adjust the treatment process, without achieving adaptive control of the treatment.

[0004] As market and user demands continue to evolve, the limitations of existing electrotherapy equipment are becoming increasingly apparent. First, most existing devices offer only simple, repetitive functions, with fixed current intensities and no effective method for assessing poor contact during treatment. Second, they all provide unidirectional, forward-direction treatment, failing to achieve a closed-loop treatment process. Relying solely on the patient's subjective experience to judge treatment effectiveness inevitably leads to suboptimal results. Third, the separation of measurement and treatment functions often necessitates the use of multiple devices in a single treatment session, making it difficult to meet modern diagnostic and treatment needs. Fourth, human-computer interaction is either mechanically controlled or merely uses touchscreens instead of traditional mechanical buttons, failing to fully utilize human-computer interaction capabilities.

[0040] Example 1

[0041] Please see Figure 1 , Figure 1 This is a structural block diagram of an integrated diagnostic and therapeutic device for human composite parameter measurement and photoelectric therapy provided in an embodiment of the present invention. It includes: a signal acquisition module, a signal processing module, a feature extraction module, a parameter generation module, a photoelectric synchronous therapy module, a treatment status monitoring module, an adaptive control module, a treatment evaluation module, and a treatment model memory optimization module; wherein,

[0050] The treatment model memory optimization module is used to store all the data of this treatment after the treatment is completed, and to optimize and iterate similar treatment parameters after remembering similar treatment processes multiple times, so as to provide better treatment results in the next treatment.

[0051] In this embodiment, the various modules used to implement the device's functions can be integrated inside the main body of the diagnostic and treatment device. For example, please refer to... Figure 2 , Figure 2 This is a schematic diagram of the internal structure of an integrated diagnostic and treatment device for human composite parameter measurement and photoelectric therapy provided in an embodiment of the present invention. It includes an upper plate 1 and a bottom plate 2. The upper plate 1 is a control plate, and the bottom plate 2 is a detection and treatment plate. The upper plate 1 and the bottom plate 2 are connected by a board-to-board connector 5 for signal and power transmission. At the same time, the upper plate 1 and the bottom plate 2 are fixedly connected by a connecting post 4.

[0052] Furthermore, the temperature measurement unit includes several temperature probes, and the impedance measurement unit includes several impedance probes. Both the temperature probes and impedance probes are disposed on the base plate inside the main body of the diagnostic and therapeutic device, and are evenly distributed in different positions. Figure 2 The number 3 in the figure represents a temperature probe or an impedance probe.

[0053] Alternatively, as one implementation method, such as Figure 3 As shown, Figure 3 This is a schematic diagram of the base plate of an integrated diagnostic and treatment device for measuring composite human body parameters and photoelectric therapy provided in an embodiment of the present invention. This embodiment designs eight probes 3, including a temperature probe 3-1 and an impedance probe 3-2, to detect the distributed temperature value (temperature data) and impedance value (impedance data) of the human body.

[0054] In addition, the base plate 2 is also equipped with a temperature channel selection unit (not shown in the figure), an impedance channel selection unit (not shown in the figure), a mode selection module (not shown in the figure), and infrared LEDs 6; among which,

[0055] The temperature channel selection unit is connected to the temperature measurement unit, and the impedance channel selection unit is connected to the impedance measurement unit.

[0056] The mode selection module is used for device mode switching; when the device is in detection mode, the impedance probe is used to measure impedance data, and when the device is in treatment mode, the impedance probe is used as a treatment probe.

[0057] It should be noted that the base plate 2 is also provided with a positioning hole 7, which can correspond to the position of the human navel and is used to assist in measurement and treatment positioning.

[0058] Furthermore, the signal processing module, feature extraction module, parameter generation module, photoelectric synchronous treatment module, treatment status monitoring module, adaptive control module, treatment evaluation module, and treatment model memory optimization module are all integrated on the upper board inside the main body of the diagnostic and treatment equipment, and the modules are electrically connected to each other for data interaction.

[0059] In addition, the upper board 1 is also equipped with a power module, a Bluetooth module, a microcontroller, and a human-machine interface module; among which,

[0060] The power module supplies power to the entire device;

[0061] The Bluetooth module connects to the human-machine interface module to transmit the device's detection and treatment data to the human-machine interface for display.

[0062] The microcontroller connects to the signal processing module, feature extraction module, parameter generation module, photoelectric synchronous treatment module, treatment status monitoring module, adaptive control module, treatment evaluation module, and treatment model memory optimization module to control the operation of each module.

[0063] Furthermore, the phototherapy module includes a phototherapy unit and an electrotherapy unit; among which,

[0064] The phototherapy unit includes a constant current drive circuit and the aforementioned infrared LED beads. The constant current drive circuit is controlled by the PWM duty cycle, thereby controlling the orientation, time, and intensity of the phototherapy. At the same time, the phototherapy intensity can be monitored by the temperature measurement unit.

[0065] The electrotherapy unit includes a digital-to-analog converter circuit, an output amplifier circuit, and a voltage-controlled constant current source circuit. The microcontroller controls the digital-to-analog converter circuit to generate various waveforms, frequencies, and modulation signals of varying strengths. These signals are then amplified by the output amplifier circuit and fed into the voltage-controlled constant current source circuit to output a constant and adjustable current.

[0066] In this embodiment, the PWM duty cycle is positively correlated with the treatment intensity. The duty cycle is adjustable from 0 to 100 and corresponds to the phototherapy intensity. The phototherapy intensity is fed back in real time through the temperature measurement unit. The diagnostic and treatment equipment realizes the combined photoelectric integrated treatment function through the synchronous treatment module.

[0067] Furthermore, the main controller controls the digital-to-analog converter circuit through the SPI interface, and controls the DA module (i.e., the aforementioned digital-to-analog converter circuit) and the programmable amplifier (i.e., the aforementioned output amplifier circuit) to output therapeutic signals of various frequencies, waveforms and intensities. The output time, waveform, intensity and frequency of the therapeutic signals can be set. The treatment time is determined by the microcontroller's internal timer. When the timer expires, an interrupt is triggered, and the microcontroller responds to end the treatment. The treatment intensity is amplified in two stages by the DA module and the amplifier circuit. Specifically, the DA module is 12-bit, and its maximum discrete value is 4095, corresponding to the maximum voltage amplitude that the DA module can output. Changing the discrete value changes the output voltage. The programmable amplifier is controlled by the microcontroller via the SPI interface to control the amplification gain. The diagnostic and treatment equipment can output treatment waveforms such as continuous waves, discontinuous waves, and sparse and dense waves. The output waveforms are triangular waves, square waves, sine waves, etc., with 8 output treatment channels. The amplified treatment signal enters the constant current holding circuit (i.e., the voltage-controlled constant current source circuit mentioned above), and is boosted to 36V by the boost circuit, so that the output treatment current will not change due to sudden changes in the contact impedance of the treatment probe.

[0068] In this embodiment, the temperature measurement function is mainly realized by a high-precision thermistor, an analog filter and digital-to-analog converter, and a temperature channel selection unit. The Huygens bridge temperature measurement structure, composed of thermistors as temperature probes, is evenly distributed in eight areas on the lower plate. The device can realize the temperature distribution measurement of the human body surface in eight areas. The microcontroller integrated on the upper plate processes the collected temperature data to realize high-precision temperature measurement.

[0069] Furthermore, the impedance measurement function is mainly realized by the impedance probe and the impedance channel selection unit. The device can detect the distributed impedance value of the human body through the impedance measurement probes in eight directions. The main controller can control the impedance measurement of eight areas. The microcontroller integrated on the upper board realizes the accurate measurement of human body impedance parameters by performing data correction processing on the original impedance value. The electrotherapy function and the impedance measurement function of the device are switched through the mode conversion module. The default state of the mode conversion module is electrotherapy.

[0070] This embodiment employs a high-precision NTC thermistor temperature sensor for temperature measurement, achieving high-precision and real-time body surface temperature measurement through hardware circuitry and software algorithms. The temperature sensor and three high-precision resistors form a Huygens bridge temperature measurement structure. When the body surface temperature changes, the resistance of the temperature sensor changes accordingly, causing a change in the differential voltage output of the bridge. The output differential voltage is processed by an analog filter and then sent to a 24-bit high-precision analog-to-digital converter for acquisition. The microcontroller communicates with the analog-to-digital converter via a parallel interface, greatly improving the data transmission rate and ensuring the consistency and synchronization of eight-channel sampling, meeting the requirements of real-time and high-precision acquisition scenarios. Simultaneously, the clock of the analog-to-digital converter is obtained from a separate, highly reliable, low-drift external passive crystal oscillator circuit. The microcontroller simultaneously reads the temperature sensor values ​​from eight locations via the parallel interface. After reading the temperature data from the eight corresponding sensors, the data is processed by a temperature data algorithm to achieve high-precision body surface temperature measurement from all eight locations. The measured temperature data is updated in real-time to a touchscreen or mobile app, and simultaneously used as a temperature control signal for phototherapy in diagnostic and therapeutic devices to adjust the intensity of phototherapy in real time.

[0071] In this embodiment, the NTC thermistors are arranged as follows: Figure 3 As shown, high-precision NTC sensors are distributed in eight directions. The process of the microcontroller acquiring body surface temperature is as follows: each temperature measurement area has four temperature measurement circuits to ensure the real-time acquisition of temperature in each area. The four temperature sensors are synchronously sampled and output to the microcontroller in parallel. In terms of software design, the analog-to-digital converter is configured for synchronous sampling and parallel output. In terms of hardware, a synchronous sampling circuit is designed, which connects four eight-channel analog switches in series. The analog switches use address encoding to select specific input / output port pairs. The input ports of the analog switches are connected to the output terminals of the temperature sensing circuits, and the output ports are connected to the sampling input ports of the analog-to-digital converter. The address encoding control terminals of the four analog switches are connected in series, thereby realizing the synchronous control of the four thermistors in each area in hardware, achieving synchronous sampling in each area.

[0072] In this embodiment, the signal processing module processes and calibrates the temperature and impedance data as follows:

[0073] First, the microcontroller internally uses a moving average filtering algorithm to reduce acquisition errors in the collected temperature data. Specifically, the first 20 collected temperature data points are stored in an array. Subsequent data samples are averaged with the previous 20 data points each time they are collected, resulting in a valid sample value, which is then stored in the array. Finally, the earliest sampled temperature data is filtered according to a first-in, first-out (FIFO) principle, thus improving the accuracy of temperature sampling. In the hardware circuit, an analog filtering circuit is used after the temperature-measuring bridge structure to perform hardware filtering on the output voltage, further enhancing sampling accuracy.

[0074] The temperature data calibration process is as follows: The calibration range is the human body surface temperature between 35℃ and 43℃. Within this range, the relationship between temperature and resistance is approximately linear, without any nonlinear factors. A voltage-temperature correspondence table is constructed. Specifically, based on the inherent resistance-temperature relationship of the thermistors, when the body surface temperature changes, the resistance of the temperature sensor will change accordingly, causing a change in the differential voltage output of the temperature measuring bridge. This yields the corresponding temperature-voltage relationship. The microcontroller can then obtain the corresponding temperature value for the acquired voltage by looking up the table. Each thermistor is calibrated individually. The four thermistors in each region undergo a consistent calibration using an arithmetic average filtering algorithm to ensure the accuracy of the temperature in the corresponding region. The average of the temperatures collected by the four temperature sensors in each region is taken every ten measurements as the effective temperature for that region. Temperature measurement in eight regions enables the monitoring of human body temperature distribution.

[0075] The integrated diagnostic and therapeutic device for human composite parameter measurement and phototherapy provided in this embodiment can simultaneously perform impedance measurement functions in eight directions. The impedance measurement section consists of impedance probes, impedance measurement output analog switches and input analog switches, and output and input impedance measurement probes. The measurement signal from the impedance measurement module is output to the output analog switch, then introduced into the human body through the impedance probes. The measurement signal returns to the input analog switch through the input impedance measurement probes, where it is sampled by the measurement module. The measurement module calculates the difference between the output and input signals and obtains the impedance value through data calibration. The input analog switches are all eight-channel and have address encoding functions. The address encoding function allows selection of the corresponding channel, which is controlled by a microcontroller. The input and output impedance probes are arranged as follows. Figure 3 Each region has three impedance probes. The output impedance probe is connected to the input analog switch by a single probe, and the input impedance probes are connected in series to the output analog switch by two probes. By controlling the address codes of the input and output analog switches of the three impedance probes in each region to be consistent, the address signals of the input and output analog switches can be connected in series to achieve synchronous control, thereby enabling synchronous measurement of the three impedance probes in each region.

[0076] In this embodiment, impedance data calibration employs a piecewise fitting method to reduce the impact of random errors and nonlinearities in measurement on the accuracy of the acquired data, thereby achieving high-precision measurement. The adaptive control module performs data fitting processing on the raw impedance values ​​returned by the impedance measurement module to optimize random errors in the measurement process. Different fitting matching algorithms are set according to the measured impedance range and measurement impedance accuracy, and a piecewise fitting method is adopted to ensure that each segment of impedance measurement achieves optimal accuracy.

[0077] Specifically, the adaptive control module determines the range of sampled impedance values ​​and categorizes them into the first classification interval. Then, it refines the range multiple times, classifying them into different impedance intervals. Different fitting algorithms are used for impedance and temperature calibration in each interval to obtain calibrated impedance data. For example, a linear fitting algorithm is used in the measurement range of 1kΩ to 10kΩ, while a polynomial fitting algorithm is used in the 10kΩ-20kΩ measurement range, thus achieving high-precision measurement over a wide impedance measurement range.

[0078] In addition, in this embodiment, the power module is powered by a lithium battery and is equipped with a power protection circuit to ensure the electrical safety of the device;

[0079] The power module also includes a boost circuit, a buck circuit, and a power voltage detection circuit; the boost circuit powers the photoelectric synchronous therapy module, and the buck circuit powers the other modules.

[0080] The power supply voltage detection circuit is used to detect the power supply voltage in real time and display the battery level and charging progress on the human-machine interface.

[0081] Preferably, this embodiment uses a 7.2V lithium battery for power supply.

[0082] Please see Figure 4 , Figure 4 This is a schematic diagram illustrating the workflow of an integrated diagnostic and treatment device for human composite parameter measurement and phototherapy provided in this embodiment of the invention. The specific working processes of each functional module of the integrated diagnostic and treatment device for human composite parameter measurement and phototherapy provided in this embodiment are as follows:

[0083] S1: Collect temperature and impedance data of the treatment area.

[0084] S2: Perform data processing on the temperature and impedance data to obtain high-precision temperature and impedance data. For details on the data processing process, please refer to the description above.

[0085] S3: Feature Extraction: After data calibration, extract the features of temperature and impedance data to determine whether the measurement signal is correct, that is, whether the measured temperature and impedance data are within the human body standard range. If it is incorrect, measure again; if it is correct, proceed to S4.

[0086] S4: Phototherapy parameter generation: Based on the actual measured temperature and impedance values ​​of the treatment area and the information stored in the treatment model optimization memory module, reasonable treatment parameters are automatically generated. The treatment parameters include suggested treatment location, time and intensity, etc.

[0087] Optionally, the device compares the relative values ​​of temperature and impedance collected from eight locations using the holographic theory of the umbilicus in traditional Chinese medicine. The location with the lowest relative values ​​of both temperature and impedance is selected as the recommended treatment location. At the same time, the lower the relative values ​​of impedance and temperature, the longer the treatment time and the higher the intensity.

[0088] S5: Photoelectric Synchronous Therapy: Based on the above treatment parameters, a safe and controllable treatment signal is output through the synchronous therapy module.

[0089] S6: Treatment Status Monitoring: The intensity of light therapy is acquired in real time via a temperature measurement unit; the output electrotherapy signal is transmitted to the human body through a treatment probe and then collected by a sampling probe. The treatment current enters a sampling circuit to collect the treatment current in real time. The treatment and sampling probes are multiplexed with the impedance measurement probe, and are converted via a mode conversion module. Simultaneously, impedance and temperature values ​​are used to determine if there is poor contact during treatment. A contact threshold is automatically generated based on individual impedance and temperature values. When the monitoring during treatment exceeds the contact threshold, the user is alerted to pay attention to the treatment contact situation.

[0090] S7: Active Disturbance Rejection and Adaptive Control: Before the treatment time is reached, when external disturbances cause changes in the sampling temperature and treatment current value, the treatment parameters are adjusted in real time based on the real-time sampling temperature and current value of the treatment area and the treatment parameters determined by the parameter determination module. The optimal treatment current range is determined in combination with the user's actual experience to maintain the best treatment effect and realize the closed-loop detection and treatment function. If the treatment time is reached, S8 is executed.

[0091] It should be noted that the device shares the same lower board probe for both electrotherapy and impedance measurement functions. The switching of the working mode is accomplished through a dual-channel analog switch. The device is in the treatment function by default. The analog switch control pin is controlled by a microcontroller. When the microcontroller controls the pin to be high, it is in treatment mode; when it is low, it is in impedance measurement mode.

[0092] This diagnostic and treatment equipment has temperature and impedance measurement functions, as well as photoelectric therapy functions. It can be performed independently and synchronously in eight directions, and the efficacy can be evaluated after treatment, thus realizing a closed-loop integrated system of detection, treatment and evaluation.

[0093] S8: Treatment Evaluation: After each treatment, the device re-detects the temperature and impedance value of the treated area. If the temperature or impedance value of the treated area does not show an increasing trend, a negative treatment effect evaluation is given; if both the temperature and impedance value of the treated area show an increasing trend, a positive treatment effect evaluation is given. A positive treatment effect evaluation indicates that the desired treatment state has been achieved, and S9 is executed.

[0094] S9: Treatment Model Memory Optimization: After the treatment is completed, all data of this treatment is stored, and after remembering similar treatment processes multiple times, the algorithm is used to optimize and iterate the parameters of similar treatments in order to provide better treatment results in the next treatment.

[0095] In addition, the device can display temperature and impedance detection and phototherapy data in real time on the human-computer interaction interface. Through feature extraction processing algorithms, it can efficiently locate abnormal areas and display the measured temperature and impedance values ​​in eight directions using different color tones. For example, warm colors are given to directions with low temperature and impedance values, and cool colors are given to directions with high temperature and impedance values. In treatment mode, treatment process information is displayed in real time.

[0096] It should be noted that the analog-to-digital conversion circuit, output amplifier circuit, voltage-controlled constant current source circuit, constant current drive circuit, boost circuit, buck circuit, power supply voltage detection circuit, etc. involved in this invention are all implemented using existing circuits, and will not be described in detail in this embodiment.

[0097] The integrated diagnostic and treatment device for human composite parameter measurement and photoelectric therapy provided by this invention can perform high-precision synchronous measurement of human body distributed temperature and impedance data, and generate suggested treatment parameters by comparing the relative magnitudes of the collected distributed temperature and impedance values. During the treatment process, temperature and treatment current are detected to monitor the treatment status in real time and automatically adjust the treatment intensity to achieve adaptive control, thus realizing the safety and efficiency of the treatment process and overcoming the treatment safety and poor contact problems faced by traditional therapeutic instruments. At the same time, the reverse treatment concept and cascade control concept are introduced.
