Description

Technical Field

[0001] This invention relates to the field of skin care and repair technology, specifically to a physiotherapy device. Background Technology

[0002] Physiotherapy equipment is widely used in many fields such as facial care and anti-aging. Among them, radio frequency, laser, phototherapy, and microcurrent equipment are widely used in clinical practice and beauty salons.

[0003] However, existing physiotherapy equipment generally suffers from a lack of diverse control methods. Most devices typically rely on fixed parameters, such as frequency and energy intensity. While this single control method is simple, it cannot adapt to different skin types and individual differences. To address this issue, some devices use feedback adjustments based on detected skin parameters to modify output parameters. However, most devices still rely on adjusting a single parameter for output, resulting in limited therapeutic functionality and a higher risk of side effects such as skin irritation and pain when the output intensity is too high, negatively impacting the user's treatment experience. Summary of the Invention

[0004] In view of this, the present invention provides a physiotherapy device to solve the problem that the existing physiotherapy devices have single control parameters and poor comprehensive skin physiotherapy effect.

[0005] In a first aspect, the present invention provides a physiotherapy device, the physiotherapy device comprising: The probe device includes an output module for transmitting a combined signal to a target area, the combined signal being used to adjust the TRP channel target point in the target area; The control module is connected to the probe device. The control module includes a frequency modulation unit and a pulse modulation unit. The frequency modulation unit is used to generate a target frequency signal, and the pulse modulation unit is used to convert the target frequency signal into a combined signal of target pulse parameters. The main control module, connected to the control module, is used to retrieve at least one set of target combination parameters from the parameter matrix and the preset target point correspondence table, and control the control module to generate the combination signal corresponding to the target combination parameters; the parameter matrix and the preset target point correspondence table include combination parameters that correspond one-to-one with the TRP channel target points, and the target combination parameters include frequency parameters and pulse parameters.

[0006] This invention provides a method for actively regulating the electrical signal stimulation of specific TRP channels within different layers of skin tissue through controllable physical technology, specifically through combinations of frequency and pulse width. By setting multiple combinations of frequencies and pulse widths, selective regulation of different TRP thermosensitive ion channels can be achieved without relying on real-time detection feedback, i.e., without parameter feedback. This results in multi-level skin treatment effects such as epidermal barrier repair, dermal immune balance, and nerve ending analgesia. This breakthrough overcomes the conventional "detection-regulation" feedback logic of existing technologies and establishes a novel "combined output-channel regulation-effect targeting" technology, which has broad application prospects.

[0007] In one alternative implementation, the physiotherapy device further includes: The control interface, connected to the main control module, is used to respond to user input of TRP channel target points and corresponding combination parameters, and to generate a one-to-one corresponding control mode based on the TRP channel target points and combination parameters, and store it in the main control module; the control mode is for user selection.

[0008] In this embodiment, by setting a control interface, different "frequency + pulse width combination modes" can be set. Through the preset control mode, not only is the personalization and pertinence of clinical operation improved, but the operation process can also be effectively simplified, and the operation efficiency and convenience can be improved.

[0009] In one optional implementation, the control interface is also used to respond to the target control mode selected by the user and send a response command to the main control module; the main control module retrieves the target combination parameters corresponding to the target control mode based on the response command.

[0010] This implementation can automatically adjust parameters according to the patient's real-time needs, ensuring a more personalized, flexible, and efficient treatment process.

[0011] In an optional implementation, the probe device is also connected to the main control module, and the probe device further includes: The control handle includes several control buttons, each corresponding to a different control mode.

[0012] In this embodiment, each control button corresponds to a specific adjustment mode, making the operation more intuitive and convenient, reducing the complexity of operation, greatly improving the efficiency and flexibility of the operation process, and enhancing the patient's comfort and satisfaction.

[0013] In one alternative implementation, the combination parameters are selected from a pre-established parameter lookup table; The parameter reference table includes multiple preset combination parameters, each containing a corresponding frequency parameter range and pulse parameter range. Each preset combination parameter is used to adjust the TRP channel target points in different layers of the target region.

[0014] In this embodiment, by pre-setting a treatment program, a programmed, multi-stage synergistic intervention on the barrier, immunity, and pain can be effectively achieved.

[0015] In one optional implementation, the preset combination parameters include: The first preset combination parameters are used to adjust the TRPV1 target point in the epidermal layer of the target area. The second preset combination parameters are used to adjust the TRPV3 and TRPV4 target points in the epidermal layer of the target area. The third preset combination parameter is used to adjust the TRPA1 target point in the dermis of the target area; The fourth preset combination parameter is used to adjust the TRPV3 and TRPV4 target points in the dermis of the target area; The fifth preset combination parameter is used to adjust the TRPA1 target point in the subcutaneous layer of the target area; The sixth preset combination parameter is used to adjust the TRPM8 target point in the subcutaneous layer of the target area.

[0016] In one optional implementation, the frequency parameter in the first preset combination parameters is selected from a range of 6.5 kHz to 8 kHz, and the pulse parameter is selected from a range of 60 μs to 120 μs. The frequency parameter in the second preset combination parameters has a selection range of 5kHz to 6.5kHz, and the pulse parameter has a selection range of 120μs to 180μs. The frequency parameter in the third preset combination parameters has a selection range of 3.5kHz to 4.5kHz, and the pulse parameter has a selection range of 180μs to 260μs. The frequency parameter in the fourth preset combination parameter has a selection range of 4.5kHz to 5.5kHz, and the pulse parameter has a selection range of 150μs to 240μs. The frequency parameter in the fifth preset combination parameter has a selection range of 2.8kHz to 4kHz, and the pulse parameter has a selection range of 220μs to 320μs. The frequency parameter in the sixth preset combination parameter has a selection range of 2kHz to 2.8kHz, and the pulse parameter has a selection range of 260μs to 360μs.

[0017] In this embodiment, procedural intervention in multi-level organizations can be achieved through the sequential or synergistic effects of different combination modes.

[0018] In one optional implementation, the control module further includes a signal synthesis unit, which, when there are two or more sets of target combination parameters, performs data processing on two or more sets of frequency parameters and pulse parameters in the target combination parameters using direct digital synthesis technology to obtain synthesized frequency parameters and synthesized pulse parameters; the control module generates a combined signal based on the synthesized frequency parameters and synthesized pulse parameters.

[0019] In this embodiment, the control module can generate synthetic frequency parameters and synthetic pulse parameters, thereby producing a precise combined signal, which can effectively improve control efficiency and comprehensive treatment effect.

[0020] In an optional implementation, the probe device is also connected to the main control module, and the probe device further includes: The skin conductivity sensor, electrically connected to the main control module, is used to detect the conductivity parameters of the target area and send the conductivity parameters to the main control module; The main control module is also used to determine whether there is sensitivity in the target area based on the conductivity parameters, and to display the judgment result on the control interface.

[0021] In this embodiment, the skin conductivity sensor detects changes in conductivity in the target area in real time, ensuring immediate feedback on skin condition and providing efficient information support for medical personnel, which can effectively improve diagnostic efficiency.

[0022] In an optional implementation, the probe device is also connected to the main control module, and the probe device further includes: The spectral sensor, electrically connected to the main control module, is used to detect the spectral parameters of the target area and send the spectral parameters to the main control module. The main control module is also used to determine whether there is inflammation in the target area and to display the results on the control interface.

[0023] In this embodiment, the presence of inflammation or other abnormalities in the skin is inferred by a spectral sensor, and the results are displayed on the control interface. This can effectively help users make more accurate judgments and improve diagnostic efficiency. Attached Figure Description

Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0029] Furthermore, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0030] This embodiment provides a physiotherapy device. Figure 1 This is a schematic diagram of the structure of a physiotherapy device according to an embodiment of the present invention, including a probe device, a control module, and a main control module, as detailed below.

[0031] The probe device includes an output module for transmitting a combined signal to a target area, which is used to adjust the TRP channel target point in the target area.

[0032] In this embodiment, the combined signal emitted by the output module includes both frequency signals and pulse signals. Furthermore, the combined signal can be a single combined signal, i.e., it includes only one set of frequency signals and one set of pulse signals; or it can be a composite combined signal, i.e., it includes two or more sets of composite frequency signals and two or more sets of composite pulse signals.

[0033] The combined signal is emitted to a target area, which can be a local skin region. The emitted combined signal is primarily used to modulate TRP (transient receptor potential) channel targets at different layers of the skin.

[0034] TRP channels are an important family of ion channels, with many different types, each responding to specific external stimuli, including temperature, physical stimuli, and chemical stimuli. TRP channels play crucial roles in barrier function, immune homeostasis, temperature perception, and pain transmission. For example, TRPV1 channels are highly sensitive to temperature changes and play a key role in pain perception and burning responses. TRPV1 is an important target for inhibiting pain and sensitivity. TRPA1 plays a key role in pain, inflammation, and chemoreception, and is an important target for inhibiting inflammation. TRPV3 is a heat-sensitive ion channel that plays an important role in improving skin barrier function and promoting skin repair and regeneration. TRPV4 channels are highly sensitive to changes in temperature, mechanical pressure, and body fluid pressure; TRPV4 plays an important role in inhibiting vasodilation and barrier regulation. TRPM8 primarily senses low temperatures and cold sensations; TRPM8 is a potential target for treating cold-related pain and providing analgesia.

[0035] The control module is connected to the probe device. The control module includes a frequency modulation unit and a pulse modulation unit. The frequency modulation unit is used to generate the target frequency signal, and the pulse modulation unit is used to convert the target frequency signal into a combined signal of target pulse parameters.

[0036] Specifically, the frequency modulation unit can use an oscillator, which can generate signals of different frequencies. The pulse modulation unit can use a pulse modulation circuit, which can convert the continuous wave signal output by the oscillator into specific pulse parameters, such as pulse width and duty cycle, thereby generating a combined signal of frequency and pulse width.

[0037] For example, a combined signal with a frequency parameter of 7.2 kHz, a pulse width of 90 μs, a duty cycle of 30%, and a pulse train duration of 3 min can be generated to suppress the TRPV1 target.

[0038] Furthermore, the control module in this embodiment also employs DDS (Direct Digital Synthesizer) technology, supporting multi-frequency and multi-pulse-width combined outputs, and can simultaneously generate composite waveforms to achieve multi-mode collaborative operation. That is, when there are multiple sets of target combined parameters, the control module can also output combined signals synthesized from multiple sets of parameters, achieving multi-channel parallel control. For example, to generate a combined signal with a frequency parameter of 7.2kHz, a pulse width of 90μs, a duty cycle of 30%, and a pulse train length of 3min to suppress the TRPV1 target, a combined signal with a frequency parameter of 5.3kHz, a pulse width of 160μs, a duty cycle of 45%, and a pulse train length of 5min should also be generated to adjust the TRPV3 / 4 target. At this point, the frequency parameter 7.2kHz and the frequency parameter 5.3kHz can be synthesized using the signal synthesis unit and DDS technology; at the same time, pulse width 90μs, duty cycle 30% and pulse train 3min and pulse width 160μs, duty cycle 45% and pulse train 5min can be synthesized; thus generating the synthesized frequency parameter and synthesized pulse parameter, and then generating a combined signal based on the synthesized frequency parameter and synthesized pulse parameter.

[0039] The main control module, connected to the control module, is used to retrieve at least one set of target combination parameters from the parameter matrix and the preset target point correspondence table, and control the control module to generate the combination signal corresponding to the target combination parameters. The parameter matrix and the preset target point correspondence table includes combination parameters that correspond one-to-one with the TRP channel target points. The target combination parameters include frequency parameters and pulse parameters. The main control module is also connected to the power supply module, which provides a safe and stable current output, supporting sine waves, pulse waves, and load waveforms.

[0040] Each set of target combination parameters can adjust the same or different TRP channel target points at different levels in the target region. In this embodiment, the main control module can retrieve the corresponding combination parameters, i.e., the target combination parameters, from the pre-established parameter matrix and preset target point correspondence table in response to the user-selected control mode. The parameter matrix and preset target point correspondence table are set with combination parameters corresponding one-to-one with different TRP channel target points, such as TRPV1 corresponding to high frequency short pulse width, TRPA1 corresponding to low frequency long pulse width, etc.

[0041] Users can select two or more control modes at the same time. The main control module will then retrieve two or more sets of combined parameters according to the selected control mode, and send the retrieved combined parameters to the control module to generate the corresponding combined signal.

[0042] This embodiment provides a method for actively modulating the electrical signal stimulation of specific TRP channels within different layers of skin tissue using controllable physical techniques, specifically through combinations of frequency and pulse width. By setting multiple combinations of frequencies and pulse widths, selective modulation of different TRP thermosensitive ion channels can be achieved without relying on real-time detection feedback, i.e., without parameter feedback. This results in multi-level skin treatment effects such as epidermal barrier repair, dermal immune balance, and nerve ending analgesia. This method breaks through the conventional feedback logic of "detection-regulation" and establishes a novel technology of "combined output—target channel modulation—effect targeting," which has broad application prospects.

[0043] In some alternative implementations, the physiotherapy device further includes: The control interface, connected to the main control module, is used to respond to user-input combination parameters, generate corresponding control modes based on the combination parameters, and store them in the main control module; the control modes are available for user selection.

[0044] In this embodiment, the control interface allows users to pre-input different combinations of parameters for adjusting different TRP channels, and generates corresponding regulation modes based on these parameters. In actual use, users simply need to select the appropriate regulation mode based on the patient's clinical presentation, such as barrier repair, immune modulation, or analgesia.

[0045] In this embodiment, by setting a control interface, different "frequency + pulse width combination modes" can be set. Through the preset control mode, not only is the personalization and pertinence of clinical operation improved, but the operation process can also be effectively simplified, and the operation efficiency and convenience can be improved.

[0046] In some optional implementations, the control interface is also used to respond to the target control mode selected by the user and send a response command to the main control module; the main control module retrieves the target combination parameters corresponding to the target control mode based on the response command.

[0047] This control interface not only responds to the user's selected target adjustment mode but also translates the user's selection into response commands, which are then transmitted to the main control module. The main control module retrieves the corresponding target combination parameters based on these commands, thereby achieving precise control. This design allows for automatic parameter adjustment according to the patient's real-time needs, ensuring a more personalized, flexible, and efficient treatment process.

[0048] In some optional implementations, the probe device is also connected to the main control module, and the probe device further includes: The control handle includes several control buttons, each corresponding to a different control mode.

[0049] In actual operation, users can select the corresponding control mode based on the patient's clinical presentation by pressing the corresponding mode button. The control handle triggers a response signal sent to the main control module. The main control module responds to the control mode, retrieves the corresponding target combination parameters, controls the control module to generate a combination signal, and sends it to the output module in the probe transposition for output, thereby achieving adjustment of the TRP channel corresponding to the target area.

[0050] In this embodiment, each control button corresponds to a specific adjustment mode, making the operation more intuitive and convenient, reducing the complexity of operation, greatly improving the efficiency and flexibility of the operation process, and enhancing the patient's comfort and satisfaction.

[0051] In some optional implementations, the combined parameters include frequency parameters and pulse parameters; the combined parameters are selected from a pre-established parameter lookup table. The parameter reference table includes multiple preset combination parameters, each containing a corresponding frequency parameter range and pulse parameter range. Each preset combination parameter is used to adjust the TRP channel target points in different layers of the target region.

[0052] In this embodiment, different combinations of frequency and pulse width are used to achieve stratified selective regulation of TRP thermosensitive ion channels in skin tissue, such as TRPV1, TRPV3, TRPV4, TRPA1, and TRPM8. Frequency and pulse width are used as dual-parameter combinations, with each combination corresponding to a specific TRP channel and biological effect. Through preset treatment programs, programmed, multi-stage synergistic interventions targeting the skin barrier, immunity, and pain can be effectively achieved.

[0053] In some optional implementations, the preset combination parameters include: The first preset combination parameters are used to adjust the TRPV1 target point in the epidermal layer of the target area. The second preset combination parameters are used to adjust the TRPV3 and TRPV4 target points in the epidermal layer of the target area. The third preset combination parameter is used to adjust the TRPA1 target point in the dermis of the target area; The fourth preset combination parameter is used to adjust the TRPV3 and TRPV4 target points in the dermis of the target area; The fifth preset combination parameter is used to adjust the TRPA1 target point in the subcutaneous layer of the target area; The sixth preset combination parameter is used to adjust the TRPM8 target point in the subcutaneous layer of the target area.

[0054] In some optional implementations, the frequency parameter in the first preset combination parameters is selected from 6.5 kHz to 8 kHz, and the pulse parameter is selected from 60 μs to 120 μs. The frequency parameter in the second preset combination parameters has a selection range of 5kHz to 6.5kHz, and the pulse parameter has a selection range of 120μs to 180μs. The frequency parameter in the third preset combination parameters has a selection range of 3.5kHz to 4.5kHz, and the pulse parameter has a selection range of 180μs to 260μs. The frequency parameter in the fourth preset combination parameter has a selection range of 4.5kHz to 5.5kHz, and the pulse parameter has a selection range of 150μs to 240μs. The frequency parameter in the fifth preset combination parameter has a selection range of 2.8kHz to 4kHz, and the pulse parameter has a selection range of 220μs to 320μs. The frequency parameter in the sixth preset combination parameter has a selection range of 2kHz to 2.8kHz, and the pulse parameter has a selection range of 260μs to 360μs.

[0055] For details, please refer to Tables 1, 2, and 3. Table 1 shows the preset combination parameters for the epidermis, Table 2 shows the preset combination parameters for the dermis, and Table 3 shows the preset combination parameters for the subcutaneous layer.

[0056] Table 1

[0057] Table 1 is for the epidermis, applicable to keratinocytes and superficial nerve endings.

[0058] Key TRP targets: TRPV1 (inhibits sensitivity / burning), TRPV3 / 4 (barrier and metabolic regulation).

[0059] Starting point suggestion: Start at 7.2kHz / 90μs / 30% duty cycle, observe the sensation for 2–3 minutes, and then fine-tune the frequency (±0.5kHz) or pulse width (±20μs).

[0060] Table 2

[0061] Table 2 is for the dermis and applies to immune / vascular endothelial / fibroblast cells.

[0062] Main TRP channel targets: TRPV3 / 4 (immune and vascular response), supplemented by TRPA1 (inflammation-related, should be inhibited).

[0063] Recommended starting frequency: 4.8kHz / 200μs / 45% duty cycle. If the target is anti-inflammatory, reduce to 4.2kHz and increase the pulse width to 220–240μs.

[0064] Table 3

[0065] Table 3 lists the analgesics and anti-inflammatory effects applicable to subcutaneous / deep nerve endings.

[0066] Key TRP channel targets: TRPA1 (inhibition), TRPM8 (mild activation to achieve "cold relief" and analgesia).

[0067] Recommended starting pulse width: 3.2kHz / 280μs / 35%, adjust pulse width (±40μs) according to pain complaints and tolerance.

[0068] The following are examples of several control modes, each of which includes two sets of combined parameters.

[0069] Regulation Mode A (Sensitive Barrier Priority): a1: 7.2kHz / 90μs / 30%×3min (TRPV1 suppression); a2: 5.3kHz / 160μs / 45%×5min (TRPV3 / 4 adjustment); Regulation Mode B (Effective Immunotherapy and Analgesia): b1: 4.8kHz / 200μs / 45%×4min (TRPV3 / 4); b2: 2.8kHz / 280μs / 35%×6min (TRPA1 suppression / TRPM8 excitation).

[0070] Regulation Mode C (Deep Analgesia Priority): c1: 3.0kHz / 300μs / 35%×8min (TRPA1 / TRPM8); c2: 6.8kHz / 100μs / 30%×2min (superficial calming finish, reducing the sensation of reignition).

[0071] Note: The total duration of the same treatment is recommended to be 10–15 minutes; the interval between switching between adjacent modes is 10–20 seconds.

[0072] Waveform: Prioritize a bi-symmetrical square wave (to reduce net charge accumulation); if necessary, superimpose a light amplitude modulation (AM) / frequency modulation (FM) to improve comfort and compliance.

[0073] Multi-channel: The superficial channel uses high frequency and short pulse width, while the deep channel uses low frequency and long pulse width. It can be output synchronously (coordinated level) or sequentially (staged).

[0074] Electrode size: Use small electrodes for superficial / small target points (to increase local field strength), and large electrodes for deep / large areas (for uniform distribution).

[0075] Somatosensory monitoring: If sharp stinging occurs, slightly increase the frequency / reduce the pulse width / lower the duty cycle; if the effect is too weak, slightly decrease the frequency / increase the pulse width.

[0076] The control mode prioritizes at least the above three combinations, corresponding to the three paths TRPV1 / TRPV3-4 / TRPA1-TRPM8; it supports both sequential and synchronous multi-channel execution modes. Through the sequential or synergistic effects of different combination modes, procedural interventions at multiple organizational levels can be achieved.

[0077] In some optional implementations, the control module further includes a signal synthesis unit, which, when there are two or more sets of target combination parameters, performs data processing on two or more sets of frequency parameters and pulse parameters in the target combination parameters to obtain synthesized frequency parameters and synthesized pulse parameters; the control module generates a combined signal based on the synthesized frequency parameters and synthesized pulse parameters.

[0078] The control module in this embodiment also employs DDS (Direct Digital Synthesizer) technology, supporting multi-frequency and multi-pulse-width combined outputs, and can simultaneously generate composite waveforms. That is, when there are multiple sets of target combined parameters, the control module can also output a combined signal synthesized from multiple sets of parameters. For example, to generate a combined signal with a frequency parameter of 7.2kHz, a pulse width of 90μs, a duty cycle of 30%, and a pulse train length of 3min to suppress the TRPV1 target, a combined signal with a frequency parameter of 5.3kHz, a pulse width of 160μs, a duty cycle of 45%, and a pulse train length of 5min should also be generated to adjust the TRPV3 / 4 target. At this point, the frequency parameter 7.2kHz and the frequency parameter 5.3kHz can be synthesized using the signal synthesis unit and DDS technology; at the same time, pulse width 90μs, duty cycle 30% and pulse train 3min and pulse width 160μs, duty cycle 45% and pulse train 5min can be synthesized; thus generating the synthesized frequency parameter and synthesized pulse parameter, and then generating a combined signal based on the synthesized frequency parameter and synthesized pulse parameter.

[0079] In this embodiment, the control module can generate synthetic frequency parameters and synthetic pulse parameters, thereby producing a precise combined signal, which can effectively improve control efficiency and comprehensive treatment effect.

[0080] Currently, there is a lack of direct research on the systematic mapping of TRPV3 / 4 or TRPA1 at the skin level using "2–8kHz + specified pulse width combinations". Based on existing research, the inventors have found that: (1) kHz-level electrical stimulation can affect TRP channel-related pathways. For example, Fang et al. observed in a mouse nerve injury model that kHz high-frequency stimulation can significantly downregulate TRPV1 and relieve pain, and TRPV1 agonists can partially reverse this effect.

[0081] (2) There is a great deal of physiological evidence that HFAC / kHz stimulation can significantly alter neural activity in terms of nerve conduction blockade and sensory threshold regulation, thus providing a physical and electrophysiological basis for the mechanism of “frequency + pulse width combination affecting TRP channel” in this invention.

[0082] (3) Engineering / modeling studies on pulse width and activation depth (TENS related) also support the general conclusion that "the longer the pulse width, the easier it is to act on deep tissues," which provides support for the idea of ​​designing low-frequency long pulse widths to act on subcutaneous TRP.

[0083] (4) There is sufficient physiological evidence for the expression of TRP channels (TRPV1 / TRPV3 / TRPV4 / TRPA1 / TRPM8) in the skin, which can be used as reasonable biological targets for this invention. Furthermore, there are interactions / synergistic effects between the channels, suggesting that the multi-target combination strategy is mechanistically feasible.

[0084] In some optional implementations, the probe device is also connected to the main control module, and the probe device further includes: The skin conductivity sensor, electrically connected to the main control module, is used to detect the conductivity parameters of the target area and send the conductivity parameters to the main control module; The main control module is also used to determine whether there is sensitivity in the target area based on the conductivity parameters, and to display the judgment result on the control interface.

[0085] Skin conductivity sensors can be used to monitor the skin's conductivity, which can be used to determine whether the skin is sensitive or irritated. When the skin is sensitive, changes in sweat gland activity or blood circulation may cause alterations in conductivity, thus affecting the skin's overall conductivity. By monitoring these changes, skin sensitivity can be inferred. Furthermore, the results are sent to a control interface for display, assisting the user in making a judgment.

[0086] In this embodiment, the skin conductivity sensor detects changes in conductivity in the target area in real time, ensuring immediate feedback on skin condition and providing efficient information support for medical personnel, which can effectively improve diagnostic efficiency.

[0087] In some optional implementations, the probe device is also connected to the main control module, and the probe device further includes: The spectral sensor, electrically connected to the main control module, is used to detect the spectral parameters of the target area and send the spectral parameters to the main control module. The main control module is also used to determine whether there is inflammation in the target area and to display the results on the control interface.

[0088] Near-infrared spectroscopy technology allows spectral sensors to analyze the light absorption characteristics of the skin. Inflamed areas may exhibit different absorption characteristics under specific wavelengths of light. Spectral sensors can be used to detect changes in blood flow deep within the skin and other inflammation-related physiological changes. Furthermore, the spectral sensor data is transmitted to the main control module, which can then infer the presence of skin inflammation. The judgment result is then sent to the control interface for display, assisting the user in making a judgment.

[0089] In this embodiment, the presence of inflammation or other abnormal conditions on the skin is inferred by a spectral sensor, and the results are displayed on the control interface, which can effectively help users make more accurate judgments and improve diagnostic efficiency.

[0090] Although embodiments of the invention have been described in conjunction with the accompanying drawings, those skilled in the art can make various modifications and variations without departing from the spirit and scope of the invention, and such modifications and variations all fall within the scope defined by the appended claims.
