[0001] The present application relates to the technical field of infrared thermal radiation physiotherapy lamp, in particular to an intelligent infrared thermal radiation physiotherapy lamp based on single-shot multi-frequency demodulation-space frequency domain imaging. BACKGROUND

[0002] As a non-invasive physical treatment device, infrared thermal radiation physiotherapy lamp has rapidly penetrated in the fields of medical treatment, rehabilitation and consumer health in recent years. At present, it is commonly used in the treatment of blood vessel injury, burn treatment, diabetic foot treatment and traditional Chinese medicine rehabilitation in hospital clinical use. The main spectral wavelength is near infrared (700-1400nm) which focuses on superficial tissue repair (such as wound healing), and far infrared (>1400nm) which realizes deep thermal penetration (>70mm) and can effectively relieve muscle inflammation and joint pain.

[0003] The commonly used infrared thermal radiation physiotherapy lamp (for example, YSHT-IIA type produced by Shanghai Yuejin) on the current market is simple to use and low in cost. However, its infrared thermal radiation generation method is single, the spectrum is single and cannot be selected, its diagnosis and treatment method is fixed and cannot distinguish different types of skin damage. In addition, during the clinical diagnosis and treatment process, the state of the damaged skin cannot be monitored in real time, resulting in poor treatment effect and low efficiency of the skin damage. Therefore, we propose an intelligent infrared thermal radiation physiotherapy lamp based on single-shot multi-frequency demodulation-space frequency domain imaging. SUMMARY

[0033] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0034] Please see Figure 1 - Figure 5 This invention provides an intelligent infrared thermal radiation therapy lamp based on single-snapshot multi-frequency demodulation-spatial frequency domain imaging, comprising: a lampshade 1 and a fixing plate 8. An irradiation lamp 2 is installed inside the lampshade 1. A connecting plate 3 is fixedly installed on the upper end of the lampshade 1. A movable plate 4 is detachably installed on the upper part of the connecting plate 3 via a magnetic block. A limiting plate 6 is detachably connected to the outside of the movable plate 4 via a connecting column 5. Multiple positioning columns 7 are fixedly installed longitudinally on the upper end of the limiting plate 6, and the left side of the positioning columns 7 is detachably connected to the fixing plate 8. The left side of the limiting plate 6 is detachably connected to the fixing plate 8 via a mounting column 9. A base 11 is fixedly installed on the lower end of the fixing plate 8. The invention also includes a therapy system 12 installed on the upper left side of the base 11.

[0035] The lampshade 1 enables the installation and protection of the irradiation lamp 2; the movable plate 4, via magnetic blocks, allows for quick disassembly and installation of the connecting plate 3. Combined with the connecting column 5 and the limiting plate 6, the irradiation angle can be flexibly adjusted, thereby improving the accuracy of irradiation; the positioning column 7 is longitudinally fixed to the upper end of the limiting plate 6, and through its detachable connection with the fixed plate 8, it further enhances the adjustability and impact resistance of the structure; the fixed plate 8 provides a stable support foundation, ensuring the stability of the entire device during treatment, while its detachable connection design facilitates maintenance and cleaning; the mounting column 9 serves as a key connecting component between the limiting plate 6 and the fixed plate 8, ensuring... To ensure reliable alignment of all components during dynamic adjustment, the base 11, located at the lower end of the fixing plate 8, is designed with anti-slip material to effectively prevent the equipment from shifting during operation. It also integrates the installation interface of the physiotherapy system 12. The physiotherapy system 12 has a built-in intelligent control module that, based on single-snapshot multi-frequency demodulation-spatial frequency domain imaging technology, collects feedback data from the treatment area in real time and dynamically optimizes wavelength, light intensity, and irradiation time parameters through an algorithm model to achieve an adaptive treatment process. For example, it can automatically increase light intensity or adjust wavelength when the model output is "no change," or maintain the current settings when the condition is "improving," ensuring the continuity and efficiency of the treatment process.

[0036] The physiotherapy system 12 includes:

[0037] Optical imaging module: used to acquire visible light images of the skin, based on single snapshot multi-frequency demodulation-spatial frequency domain imaging technology, to acquire the skin's optical and physiological parameters in real time.

[0038] Data processing module: The parameters acquired by the optical imaging module are processed based on the multimodal skin damage assessment model to analyze the treatment effect of skin damage.

[0039] Infrared control module: Based on the skin damage assessment results generated by the data processing module, the output parameters of the near-infrared light source, such as wavelength selection range of 760-2000nm, light intensity, irradiation angle, and irradiation time, are dynamically adjusted, and safety is ensured through a temperature control device of 40-50℃ and an emergency braking system.

[0040] Feedback optimization module: continuously monitors skin temperature and treatment response, and dynamically optimizes the combination of output parameters based on the data obtained from the data processing module.

[0041] In this embodiment, preferably, the illumination lamp 2 is selected from either an incandescent lamp or a near-infrared LED. The wavelength range of the illumination lamp 2 covers 760–2000 nm, and the adjustable light intensity range is 0–1000 mW / cm². 2 The irradiation angle can be adjusted from 0 to 90°, and the irradiation time can be set from 1 to 30 minutes to meet the treatment needs of different skin lesions. Among them, the near-infrared LED is preferred for its high energy efficiency and low heat loss characteristics, while the incandescent lamp provides continuous spectrum irradiation. Both are dynamically optimized through the infrared control module of the physiotherapy system 12 and work together with the temperature control device to ensure that the treatment temperature is maintained within a safe range of 40 to 50°C.

[0042] In this embodiment, preferably, a magnetic block is installed on the upper left side of the connecting plate 3, and a slot is opened on the lower left side of the movable plate 4. A magnetic connecting block is installed inside the slot, and the magnetic block and the magnetic connecting block are magnetically connected. The right side of the movable plate 4 extends to the outside of the limiting plate 6, and a limiting frame is installed on the outside of the extension. The magnetic connection facilitates quick disassembly and adjustment of the position of the movable plate 4, improving the flexibility and maintenance efficiency of the equipment. The magnetic block and the magnetic connecting block use strong magnetic materials such as neodymium iron boron magnets to ensure a stable and reliable connection. The limiting frame is used to limit the movement range of the movable plate 4 to prevent displacement or detachment during physiotherapy, thereby ensuring the stability and safety of the overall structure. In addition, the extension of the movable plate 4 works in conjunction with the limiting plate 6 through the limiting frame to support the dynamic adjustment function of the irradiation lamp 2, ensuring precise alignment of the irradiation angle and position.

[0043] In this embodiment, preferably, a fixing post is installed on the left side of each positioning post 7, and a fixing hole adapted to the fixing post is opened on the right side wall of the fixing plate 8, into which the fixing post is inserted. The insertion structure facilitates quick assembly and disassembly, ensuring a stable and reliable connection. The fixing plate 8, together with the limiting plate 6 and the limiting frame, works to limit the movement range of the movable plate 4, preventing displacement or loosening during treatment, thereby ensuring the accuracy and safety of the overall equipment. It also supports the dynamic adjustment of the irradiation lamp 2, optimizing the coverage angle of infrared radiation and improving the physiotherapy effect.

[0044] In this embodiment, preferably, the left side of the limiting plate 6 has a mounting groove, which is inserted into the interior of the fixing plate 8. The mounting groove and the interior of the fixing plate 8 have concentric through holes. The mounting post 9 passes through the through holes, and both ends of the mounting post 9 are detachably connected to fasteners 10 via threads. The fasteners 10 are used to lock the mounting post 9, ensuring a stable connection between the limiting plate 6 and the fixing plate 8, preventing loosening due to vibration or external force during physiotherapy. The detachable threads also facilitate quick maintenance or replacement of components, improving the maintainability of the equipment. The concentric arrangement of the mounting groove and the through holes ensures precise alignment of the mounting post 9, thereby coordinating with the limiting frame and the extension of the movable plate 4 to precisely control the dynamic adjustment range of the irradiation lamp 2, optimize the coverage angle and position alignment of the infrared radiation, avoid deviation, and ensure the safety and reliability of the physiotherapy effect.

[0045] In this embodiment, preferably, the limiting plate 6 has a limiting groove inside for the movable plate 4 to move horizontally, and the front and back of the limiting groove have moving grooves with arc-shaped ends for the connecting column 5 to move horizontally. The arc-shaped design at both ends of the limiting groove can effectively reduce the frictional resistance of the connecting column 5 during movement, ensuring smooth horizontal movement of the movable plate 4 and avoiding jamming or shaking; the precise size of the moving groove matches the diameter of the connecting column 5, further limiting the movement trajectory of the movable plate 4 and preventing it from accidentally deviating during physiotherapy, thereby working with the fixing plate 8 and the limiting frame to achieve stable dynamic adjustment of the irradiation lamp 2, optimizing the coverage angle and position alignment of infrared radiation, and improving the safety and reliability of the physiotherapy effect; the arc-shaped structure also facilitates the buffering of the connecting column 5 at extreme positions, reducing component wear and extending the service life of the equipment.

[0046] In this embodiment, preferably, the construction of the multimodal skin damage assessment model includes the following steps:

[0047] Step 1: Collect various skin damage images: Use a convolutional neural network algorithm to classify and train visible light images to obtain a skin damage assessment model;

[0048] Step 2: Use the random forest algorithm to train the optical and physiological parameters of the data to obtain a skin damage assessment model based on SSMD-SFDI;

[0049] Step 3: Fuse the skin damage assessment model based on the convolutional neural network algorithm and the skin damage assessment model based on single snapshot multi-frequency demodulation-spatial frequency domain imaging to obtain a multimodal skin damage assessment model, and update it using transfer learning;

[0050] Step 4: The multimodal skin damage assessment model outputs three levels: no change, improvement, and deterioration. Based on the three levels of assessment results and the actual clinical situation, an infrared thermal radiation therapy lamp usage plan is generated.

[0051] In this embodiment, preferably, the optical parameters include: scattering characteristics, attenuation scattering coefficient, and heat dissipation force. Scattering characteristics are used to quantify the scattering distribution pattern of light in skin tissue, attenuation scattering coefficient is used to measure the degree of light attenuation in deep tissues, and heat dissipation force is used to assess the heat dissipation efficiency of the skin surface. The scattering characteristics, attenuation scattering coefficient, and heat dissipation force parameters are jointly modeled using a random forest algorithm to improve the accuracy of skin damage assessment based on single-snapshot multi-frequency demodulation-spatial frequency domain imaging technology. Physiological parameters include: skin hemoglobin concentration, blood oxygen saturation, melanin content, and epidermal thickness. Skin hemoglobin concentration is used to assess the skin microcirculation status, blood oxygen saturation is used to monitor tissue oxygenation level, melanin content is used to determine the degree of pigmentation, and epidermal thickness is used to assess the integrity of the skin barrier. The physiological parameters are jointly modeled using a random forest algorithm, combined with the optical parameters, to comprehensively quantify the optical characteristics and physiological state of skin tissue, thereby improving the accuracy of skin damage assessment based on single-snapshot multi-frequency demodulation-spatial frequency domain imaging technology and providing data support for personalized adjustments to infrared thermal radiation therapy plans.

[0052] In this embodiment, preferably, during the treatment time in step 4, when the model output result is "no change," a deeper wavelength is selected, the light intensity is stronger, and the irradiation angle remains at 90 degrees; when the model output result is "improvement," the wavelength, light intensity, irradiation angle, and irradiation time remain unchanged, and the treatment is completed as planned. Through the above settings, the infrared thermal radiation parameters can be dynamically adjusted based on the real-time assessment results of the skin condition, thereby optimizing the treatment effect, reducing ineffective irradiation, and improving patient comfort, while also providing a reliable basis for the continuous optimization of personalized physiotherapy plans.

[0053] Working principle and usage process of this invention: When using this device,

[0054] The user sets the treatment area and basic parameters (such as initial wavelength, light intensity, and irradiation time) through the operation interface of the physiotherapy system 12. After startup, the irradiation lamp 2 emits near-infrared radiation, while the optical imaging module acquires visible light images of the treatment area in real time through single-snapshot multi-frequency demodulation-spatial frequency domain imaging technology, and simultaneously analyzes optical parameters such as scattering characteristics, attenuation scattering coefficient, and heat dissipation, as well as physiological parameters such as hemoglobin concentration and blood oxygen saturation. The data processing module inputs the above parameters into a multimodal skin damage assessment model for real-time analysis and outputs a three-level assessment result of "no change," "improvement," or "deterioration." The infrared control module dynamically adjusts the irradiation parameters according to the assessment results: if the model outputs "no change," it automatically increases the light intensity to 120%–150% of the original set value or switches to a deep penetration wavelength of 760–900 nm; if the output is "improvement," it maintains the current parameters until the preset treatment time ends; if the output is "deterioration," it immediately reduces the light intensity to a safe threshold (≤300 mW / cm²). 2 The system shortens the irradiation time and simultaneously activates a temperature control device for forced cooling to ensure that the skin temperature is strictly controlled within the range of 40-50℃. The feedback optimization module continuously compares the changes in physiological data before and after parameter adjustments and iteratively optimizes the multimodal model output strategy. After treatment, the system automatically generates a treatment report, and the user can disassemble the movable plate 4 and the limiting plate 6 for equipment cleaning and maintenance.

[0055] Experimental Case: Burn Treatment

[0056] The patient's burned skin was placed under the imaging module to acquire images of the skin area. SSMD / SFDI technology was used to obtain epidermal thickness (0.8 mm), hemoglobin concentration (12 g / dL), and blood oxygen saturation (85%).

[0057] The data processing module determined the injury to be a burn and generated a treatment plan: wavelength 850nm, light intensity 200W / m². 2 Irradiation angle 30°, duration 20 minutes;

[0058] During treatment, the temperature control device maintains the skin surface temperature at 42°C, and the feedback module automatically shortens the irradiation time to 15 minutes after detecting that the blood oxygen saturation has increased to 90%.

Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the invention.
