Description

Technical Field

[0001] This invention relates to the field of physiotherapy devices, and more particularly to a health garment with laser physiotherapy function. Background Technology

[0002] Low-intensity weak laser therapy (LLLT) relies on non-thermal effects to achieve mitochondrial ATP proliferation in cells. Clinical trials have verified that it has a clear adjunctive therapeutic effect on aseptic inflammation of soft tissues, myofascial pain, and slow gastrointestinal motility. The mainstream therapeutic wavelengths are concentrated in 635nm, 650nm, and 808nm. Among them, the 808nm near-infrared laser can penetrate human skin to a depth of 12-15mm, which is suitable for the therapeutic needs of deep myofascial acupoints.

[0003] Existing wearable laser therapy products on the market have inherent technical shortcomings: The first type is external LED flexible light sheet therapy clothing. LED light sources have high heating power, resulting in a significant temperature rise on the surface when worn close to the skin. Prolonged continuous wear can easily cause low-temperature burns to the skin. Furthermore, LEDs are surface light sources and cannot achieve precise point-based irradiation of acupoints. This type of product has the following quantitative defects: Fiber optic mechanical adaptation defects: Elastic clothing undergoes large daily stretching deformation, and the breakage elongation of straight-line polymer optical fibers is limited. When the fabric is stretched, the optical fiber directly bears the axial tensile force, and the laser output power attenuation exceeds the effective threshold for medical use. Solution control and safety defects: The existing wearable phototherapy devices have fixed physiotherapy parameters at the factory, without cloud update channels, and do not distinguish between user self-use and doctor prescription use permissions. Users can easily cause subcutaneous capillary damage by privately increasing the laser power; at the same time, there is no real-time temperature and power monitoring module, and abnormal laser current under low voltage can easily cause the light source to burn out.

[0004] Furthermore, existing technologies have not solved the problem of lateral light leakage at the fiber optic output end. The laser scattered by the fiber sidewall can easily shine directly into the human eye, which does not meet the first-level safety protection standard for laser products. Moreover, the main control module of mainstream equipment is not detachable, clothing cannot be washed, and the hygiene of daily use is extremely poor.

[0005] Based on the above deficiencies, existing wearable laser therapy products can only be considered as consumer-grade health care products and cannot meet the requirements for compliant use as Class II medical devices. Summary of the Invention

[0006] Purpose of the invention: The invention provides a health garment with laser therapy function, which solves the problems mentioned in the background art.

[0007] Technical Solution: To solve the above-mentioned technical problems, according to one aspect of the present invention, more specifically, a health garment with programmable laser therapy function, comprising an elastic garment body, a stretchable optical fiber network embedded in the garment's interlayer, an embedded weak laser emission module, a local signal control unit, and a cloud-based external controller, the overall garment meets the requirements of basic fabric waterproofing and IP67 waterproofing of the photoelectric module, and is suitable for daily machine washing. The specific components are as follows: (1) Elastic clothing body The garments are available in four sizes (S / M / L / XL) to fit the human torso, designed for optimal body contouring. The fabric is a double-combed weft-knitted elastic fabric (80% nylon + 20% spandex) to accommodate dynamic deformations caused by breathing, bending, and raising the arms. Four pre-defined global reference structural points are established: the back center of the neckline, the lowest point of the left and right shoulder seams, the navel reference point on the front chest, and the sacral reference point on the lower back. All acupoints are located using these four reference points to establish a two-dimensional coordinate system, eliminating pattern cutting errors. A 0.4mm thick non-woven fabric layer is added to the inside of the garment to isolate the optical fiber from the skin, preventing the fiber optic protrusions from rubbing against the skin.

[0008] (2) Stretchable fiber optic network The main optical path uses a PMMA core / transparent silicone cladding stretchable polymer optical fiber with a core diameter of 0.5mm and a cladding outer diameter of 0.7mm. The material has an inherent elongation at break of 320%, meeting the extreme stretching requirements of clothing. The stitching pattern uses two standardized processes: the longitudinal stitching on the torso uses a sinusoidal waveform with a fixed amplitude of 10mm and a peak spacing of 15mm; the side waist circular stitching uses a single spiral shape with a pitch of 20mm. Both types of stitching are fixed to the fabric interlayer using a high-frequency hot-pressing process, replacing traditional needle and thread sewing and avoiding light leakage caused by needle holes damaging the fiber cladding.

[0009] Standardized fiber optic output structure: Each fiber optic output is bonded to a microlens using UV-cured optical adhesive (93.5% transmittance). The microlenses are available in plano-convex (suitable for superficial acupoints: Tian Tu, Tan Zhong) and spherical (suitable for deep acupoints: Shen Shu, Da Chang Shu), with a uniform diameter of 0.8-2mm. After beam expansion, the diameter of the emitted light spot from human skin is stabilized at 8-15mm, increasing the acupoint alignment error tolerance from ±3mm to ±9mm. A black silicone light-shielding gasket is attached to the outer ring of the output to block lateral scattering and light leakage, meeting the GB7247.1 Class 1 laser eye safety standard. All fiber optic inputs are uniformly converged to the lower right side seam of the garment and centrally connected to the optoelectronic module via an SMA905 standard fiber optic coupling interface.

[0010] This solution eliminates all detachable and sliding fine-tuning mechanical structures for optical fibers. It achieves body shape adaptation by relying on pre-production acupoint calibration and large-size microlens beam expansion for tolerance: the standard beam tolerance range is extended from ±9mm to ±12mm. Most body shape deviations are offset by the deformation of human skin and the elasticity of clothing circumference, eliminating the need for additional mechanical adjustment structures. For niche body shapes exceeding the ±12mm limit deviation, differentiated optical fiber positions are pre-fabricated only during the garment manufacturing stage, without requiring manual disassembly or sliding adjustment by the user.

[0011] (3) Embedded weak laser emission module The module is embedded and fixed inside the lower right hem of the garment, using a fully encapsulated waterproof shell of nylon and silicone. The entire unit has an IP67 protection rating and can be directly washed without disassembly, eliminating common problems of detachable structures such as loosening, detachment, and wire wear. The internal hardware includes: one single-channel semiconductor laser diode with selectable wavelengths of 635nm (superficial anti-inflammatory), 650nm (microcirculation improvement), and 808nm (deep analgesia), and a continuously adjustable rated output power of 20-100mW; and one set of 16-channel MEMS micro-light switches, with low single-channel insertion loss and short switching response delay, enabling a single laser to drive 16 independent acupoint optical paths in a time-division multiplexing manner. Safety monitoring submodule: Built-in NTC thermistor monitors laser junction temperature in real time, with a temperature control threshold of 55℃. If the temperature exceeds the threshold, the laser drive power supply is immediately cut off and a local vibration alarm is triggered. Built-in voltage sampling chip: When the battery voltage is lower than the safety threshold, the optical path is forcibly shut down to prevent low-voltage current surges from burning out the light source. Embedded physical emergency power-off button on the outside of the housing: There are no exposed detachable parts, and all power can be cut off with one click.

[0012] (4) Local signal receiving and control unit Integrated with the laser emission module, the main control uses the nRF52840 ultra-low-power MCU. Peripherals include: Bluetooth 5.2 short-range communication chip (direct connection to the APP within 10m), Wi-Fi 6 low-power submodule (long-distance data upload to the cloud), 256M non-volatile Flash memory (can locally store 500 sets of physiotherapy prescriptions and 1000 treatment logs), and a 200mAh ultra-thin soft-pack lithium polymer battery, providing 7 days of standby time and 4 hours of continuous physiotherapy. It supports USB-C magnetic fast charging. Locally fixed three-level permission storage partitions: public custom area (user-modifiable), doctor-locked area (parameters cannot be tampered with), and factory-protected area (low-level optical path parameters are prohibited from reading and writing).

[0013] (5) External cloud interaction controller The system consists of two independent apps: a user app and a doctor app. Data exchange relies on an HTTPS encrypted cloud database. The user app has a built-in knowledge base of 208 common physical ailments mapped to TCM acupoints, suitable for mild conditions such as myofascial pain, gastrointestinal disorders, and allergic coughs. It supports users setting the irradiation duration, pulse frequency (1-50Hz), laser power, and optical path timing. The doctor app has five permissions: device binding, remote prescription push, parameter access locking, treatment adherence log viewing, and abnormal data alerts. Once locked, users cannot modify the two core security parameters: laser power and single irradiation duration. The system is synchronized with the national standard GB / T 12346-2021 for TCM acupoint positioning, ensuring the legality of acupoint coordinates.

[0014] Furthermore, it also includes the entire laser programmable control process, with the following specific steps: Step 1: Prescription Generation. There are two paths: user-initiated and doctor-remote. In user-initiated mode, the APP automatically matches national standard acupoints and physiotherapy parameters based on symptoms, supporting local fine-tuning. In doctor-prescription mode, the doctor enters the patient's height, body type, and symptoms, and the system combines cloud-based human acupoint big data to generate a personalized time-series irradiation plan, which is then written to a locked storage partition.

[0015] Step 2: Local Synchronization Verification. After receiving the prescription from the cloud, the MCU automatically verifies the number of fiber optic channels installed in the garment, eliminates invalid optical paths, avoids unnecessary power consumption caused by empty channels being connected, and prompts the user to check the fiber optic interface via a pop-up window on the user's mobile phone if the verification fails.

[0016] Step 3: Time-sharing execution. The MCU drives the MEMS optical switch to turn on channel by channel according to the preset timing sequence, with a 200ms extinction buffer between adjacent channels to avoid instantaneous current fluctuations during optical path switching; during the execution process, temperature and battery voltage data are collected every 2 seconds, and the system immediately stops and uploads the abnormal log to the cloud if any abnormality occurs.

[0017] Step 4: Data Closed-Loop Traceability. After treatment, the actual irradiation duration, power, optical path number, and reason for shutdown are recorded locally and asynchronously uploaded to the cloud health record within 5 minutes. Doctors export compliance reports monthly and dynamically iterate prescription parameters.

[0018] Furthermore, it also includes the national standard method for mass production calibration of acupoints, as detailed below: S1: Body type sample collection: For a single body type, 8 healthy volunteers aged 18-45 who meet the national standard body type, have no scoliosis or anterior pelvic tilt, were selected. The body surface coordinates of 16 trunk physiotherapy acupoints were marked by a certified TCM doctor according to GB / T 12346-2021. S2: Coordinate offset calculation: Taking the four sets of reference structural points of the clothing as the origin, calculate the horizontal and vertical offset pixel values ​​of each volunteer's acupoint relative to the reference point, remove abnormal samples other than ±2 times the standard deviation, and take the mean as the mass production standard offset. S3: Cutting Piece Point Fixing: Import the average offset into the garment CAD cutting system, fix the points at the preset fiber optic output end of the cutting piece interlayer, and fix them uniformly by heat pressing. S4: Factory Adaptation for Niche and Unusual Body Types: When a user's body shape deviation exceeds the national standard's ±12mm tolerance range, the user uploads body shape data and a grid calibration photo. The factory directly fine-tunes the heat-pressing coordinates of the fiber optic output during the garment cutting stage, completing the point adaptation in one go at the factory. After the garment is delivered, there are no manually adjustable or pluggable structures, completely simplifying the garment's mechanical structure.

[0019] Beneficial effects: This invention uses high-elastic fabric and sinusoidal and spiral stretchable optical fibers, which have high breaking elongation. It is combined with multiple patterns and acupoint calibration technology, and relies on microlens beam expansion to improve the alignment error tolerance. It is suitable for most body types, and irregular body types can be finely adjusted at the factory. There is no exposed adjustment structure. A single laser source paired with a MEMS optical switch enables multi-path acupoint irradiation at different times, supports switching between multiple wavelengths, powers, and laser modes, meets the needs of deep and superficial acupoint physiotherapy, and has an extinction interval for optical path switching, ensuring stable operation; Dual-channel wireless communication, coupled with a dual-terminal app for both doctors and patients, supports remote prescription delivery, parameter control, data uploading, and health record recording. It combines the capabilities of independent use with standardized medical management, meeting the requirements for consumer healthcare and Class II medical device use. Attached Figure Description

[0020] Figure 1 This is a schematic diagram of the garment structure of the present invention; Figure 2 This is a schematic diagram of the system framework of the present invention. Detailed Implementation

[0021] To make the technical solution of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0022] Example 1: Standard M size (165 / 88A) Neck and shoulder therapy underwear (consumer-grade for personal use) This embodiment is a consumer-grade home / daily wearable laser therapy garment for ordinary office workers and students. It is mainly used for auxiliary therapy of neck and shoulder strain caused by prolonged sitting. It adopts the standard M size 165 / 88A pattern and strictly follows the complete technical architecture of this invention without any structural customization or modification.

[0023] The main fabric of the garment is a double-combed weft-knitted elastic fabric of 80% nylon and 20% spandex, with a measured maximum weft elongation of 29%, which can accommodate the dynamic deformation of the human body such as raising the head, turning the head, raising the arm, and bending over. The garment establishes an acupoint coordinate system based on four reference points: the back center of the neck, the lowest point of the shoulder seam, the navel on the chest, and the sacrum on the lower back, completely eliminating the point position errors caused by pattern cutting. The inner side of the garment is equipped with a 0.4mm integrated non-woven fabric isolation layer, which completely isolates the fiber optic network from the human skin, avoiding discomfort caused by the hard structure of the fiber optics rubbing against the skin, and ensuring the airtightness of the interlayer without any additional sliding or plugging mechanical slots.

[0024] The interlayer is equipped with six stretchable polymer optical fibers. The fibers are all made of PMMA core with a core diameter of 0.5mm and an outer cladding diameter of 0.7mm, with a transparent silicone cladding. The material has an inherent elongation at break of 320%, which can fully withstand the extreme stretch of the fabric. The optical fibers in the neck and shoulder area are all laid with sinusoidal waves. The standardized parameters are an amplitude of 10mm and a peak spacing of 15mm. They are fixed to the fabric interlayer through a high-frequency hot pressing process, which abandons the traditional needle and thread sewing method and eliminates the risk of lateral light leakage caused by pinhole damage to the fiber cladding. Six optical fibers precisely correspond to four groups of superficial acupoints for neck and shoulder therapy: Fengchi (GB20), Jianjing (GB21), Dazhui (GV14), and Tianzong (SI11). The fiber outputs are bonded to 1mm diameter plano-convex microlenses using UV-cured optical adhesive (93.5% light transmittance). These microlenses are suitable for superficial acupoints with a subcutaneous depth of ≤5mm. After beam expansion, the diameter of the emitted light spot from the skin is consistently 10mm. Combined with black silicone lateral light-shielding gaskets attached to the outside, fiber optic scattering and light leakage are completely blocked, meeting the GB 7247.1 Class I laser eye safety standard. The overall acupoint alignment tolerance range is ±9mm. All fiber inputs are uniformly converged at the lower right side seam of the garment and centrally connected to the weak laser emission module via an SMA905 standard fiber optic coupling interface.

[0025] The low-power laser emission module, embedded in the hem of the garment, is fully encapsulated in nylon and silicone, achieving an IP67 protection rating. It supports direct washing with room temperature water, and the optical and electrical circuits function normally after washing. The module incorporates a single-channel 808nm semiconductor laser diode with a rated output power of 60mW, paired with a 16-channel MEMS micro-light switch. In this embodiment, 8 channels are actually used to achieve single-source multi-channel acupoint time-division multiplexing irradiation. The operating mode uses an 8Hz pulsed laser, which is a standard setting within the 1-50Hz pulse range supported by the device. The module incorporates an NTC thermistor as a temperature sensing element, with a laser junction temperature safety threshold set at 55℃. If this threshold is exceeded, the laser drive power is cut off within 0.5 seconds, triggering a local vibration alarm. It also features a voltage sampling chip for low-voltage power-off protection, and a hidden physical emergency power-off button is embedded on the outside of the casing, with no exposed removable parts.

[0026] The local signal control unit uses the nRF52840 ultra-low-power MCU, integrating dual-channel Bluetooth 5.2 near-field communication (direct connection to the user's app within 10 meters) and Wi-Fi 6 low-power long-range communication. It is equipped with 256MB of non-volatile Flash memory, capable of locally storing multiple sets of physiotherapy prescriptions and usage logs. It features a 200mAh ultra-thin soft-pack lithium polymer battery, providing up to 7 days of standby time and up to 4 hours of continuous physiotherapy use in real-world testing. It also supports USB-C magnetic fast charging. This product is designed for consumer-grade self-use, prioritizing the user-defined public area within the three-level access control storage partition. Users can independently modify parameters such as laser power, pulse frequency, and irradiation duration. The factory-installed optical path protection area and doctor parameter lock area remain read-only encrypted.

[0027] User Operation Process: After donning the clothing, open the user-end APP. The APP has a built-in knowledge base of 208 physical ailments and TCM acupoint mappings. Select the preset "Sedentary Neck and Shoulder Strain" program. The system automatically matches the corresponding acupoints and physiotherapy parameters according to the national standard GB / T 12346-2021: pulse frequency 8Hz, single acupoint single irradiation 4 minutes, and a 200ms extinction interval reserved for optical path channel switching. After the device starts up, the local MCU automatically completes optical path verification, automatically identifies and eliminates failed fiber optic channels, and collects laser temperature and battery voltage data every 2 seconds during operation. If any abnormality is detected, the device will immediately shut down for protection.

[0028] Example 2: Doctor remotely prescribes a back and waist therapy garment (medical use in compliance with regulations) This embodiment is applied to home rehabilitation scenarios for chronic lumbar muscle strain (Class II chronic disease). It is a medical-grade laser therapy garment, using size L (170 / 92A). The fabric tension is optimized for large-amplitude limb movements such as bending, twisting, and turning. The fabric is still made of 80% nylon and 20% spandex elastic knitted material. The acupoints for lumbar and back therapy are marked with the lumbosacral bone and navel as the core reference points. The inner one-piece non-woven fabric interlayer realizes the isolation and protection of the optical path structure, meeting the hygiene requirements for daily use of medical devices.

[0029] The stretchable fiber optic network in the ring-shaped area of ​​the waistband of the garment uses a single helical cable with a standard pitch of 20mm. It is also fixed using a high-frequency hot-pressing process, without any detachable or sliding mechanical adjustment structures. The fiber uses standard PMMA core silicone clad stretchable fiber to ensure that the fiber does not bear excessive axial tension during significant waist deformation. The fiber output end is uniformly equipped with a spherical microlens, specifically designed for deep acupoints on the lower back (5-15mm subcutaneously), such as Shenshu, Dachangshu, and Huantiao. After beam expansion, the skin spot diameter is controlled at 8-12mm, and a black silicone light-shielding gasket is used, strictly adhering to laser safety regulations. The entire optical path is fixed according to the national standard acupoint mass production calibration method, and the acupoint coordinates are in accordance with GB / T 12346-2021, ensuring the legal and accurate positioning of therapeutic acupoints.

[0030] The low-powered laser emission module retains its IP67 fully enclosed waterproof structure, allowing for complete water washing and making it suitable for both medical institutions and home use. The module is equipped with an 808nm near-infrared laser diode (penetrating human skin to a depth of 12-15mm, providing analgesia and physiotherapy for deep myofascial inflammation). Its operating mode is set to continuous laser mode, distinct from pulse mode, catering to the long-term rehabilitation needs of chronic diseases. The output power is fixed at 55mW. A multi-channel MEMS optical switch enables single-source time-division irradiation of three acupoints, with a 200ms extinction interval maintained between adjacent optical path channel switching to avoid instantaneous current fluctuations during switching. The safety protection system has been fully upgraded: In addition to the basic 55℃ junction temperature hard cut-off threshold (power off in 0.5s over-temperature + local vibration alarm), an additional 53℃ warning temperature is set. When the laser temperature is higher than the warning value for 3 consecutive seconds, the equipment will automatically shut down and trigger multi-level warnings simultaneously; the low voltage monitoring function is always on. When the battery voltage is lower than the safety threshold, the optical path will be forcibly shut down to prevent low voltage current surges from burning out the laser source. The embedded emergency power-off button can realize one-button power-off of the entire machine.

[0031] The local signal control unit continues the dual-path wireless communication architecture, with Bluetooth 5.2 used for local device debugging and Wi-Fi 6 responsible for real-time data uploads to the cloud. Data transmission relies entirely on HTTPS encryption of the cloud database. This embodiment utilizes a doctor parameter locking area within a three-level permission storage partition, a core design feature for medical control: orthopedic surgeons remotely bind the device ID via a dedicated doctor's app, establishing a personalized health record for both patient and doctor, recording patient information such as height, body type, disease course, and symptoms. The system then combines cloud-based big data on human acupoints to generate personalized treatment prescriptions, which are encrypted and pushed to the local control unit and written to the locked partition. Prescription parameters include: laser wavelength 808nm, continuous laser mode, output power 55mW, timed irradiation of three acupoints (Shenshu / Dachangshu / Huantiao), 10 minutes of single-acupoint irradiation, twice-daily scheduled treatment, and a complete treatment course of 14 days. After parameter locking, the core security parameter controls in the user's app—laser power and single irradiation duration—are directly grayed out and disabled, preventing local tampering; users can only view the device's operating status. The underlying factory-installed optical path protection zone provides full-process encrypted read / write protection, ensuring the security of the device's basic optical path.

[0032] Complete Operation Flow: After receiving the encrypted prescription from the cloud, the local MCU first automatically verifies the validity of all fiber optic paths, eliminates faulty channels, and alerts the user via a pop-up window on their mobile phone. After verification, it drives the MEMS optical switch to operate according to a preset timing sequence. During operation, temperature and voltage data are collected every 2 seconds and uploaded to the cloud in real time. When the device triggers a temperature abnormality shutdown, in addition to the local vibration alarm, alarm information is simultaneously pushed to the cloud backend and the doctor's mobile app, and a text message warning is sent to the doctor's registered mobile phone number, enabling remote real-time monitoring.

[0033] Example 3: Semi-customized body modification solution for abnormal waist circumference This embodiment addresses the semi-customized modification of garments for individuals with irregular body shapes and abnormal postures that exceed the tolerance range of standard patterns. It strictly adheres to the design principle of this invention: "one-time fine-tuning of points at the factory, no manual adjustment structure after garment production." The basic pattern uses standard size M (165 / 88A), with a standard waist circumference limit of 84cm. The user's measured parameters are: height 170cm, waist circumference 92cm, which exceeds the tolerance range of the standard pattern. At the same time, the user also has a slight anterior pelvic tilt, causing the longitudinal position of acupoints on the torso to shift. If standard fiber optic points are used directly, the acupoints will be misaligned. Therefore, a special modification is carried out by initiating the national standard acupoint mass production calibration process.

[0034] In the initial data collection phase of the renovation: users upload their height, waist circumference, and body shape description information through the user-end APP, and submit photos of the human torso grid calibration; factory technicians combine four benchmark points (with the navel and lumbosacral bone as the core) and refer to the GB / T12346-2021 national standard acupoint coordinates to calculate the horizontal and vertical offset of target acupoints such as Dachangshu relative to the standard points under the body shape of anterior pelvic tilt and large waist circumference, and determine the final renovation parameters after eliminating abnormal data.

[0035] In the garment pattern cutting and fiber optic network customization and modification process: the overall fabric, interlayer structure, and non-woven fabric sealed design completely follow the standard M-size pattern, without adding any sliding grooves, plug-in interfaces, adjustment knobs, or other mechanical adjustment structures, maintaining the integrated sealed characteristics of the interlayer. The basic optical fiber still uses PMMA core silicone clad stretchable polymer fiber, utilizing its 320% high breaking elongation to adapt to the stretching deformation of the fabric after the waist circumference increases; for the original spiral fiber routing on the waist side, the body waveform curvature is simultaneously finely adjusted to ensure that the fiber is subjected to uniform force when the fabric is stretched and twisted, and to prevent the problem of excessive axial tension causing laser power attenuation. The core modification point is the fiber optic output end corresponding to the bilateral Dachangshu points: the calculated offset data is imported into the garment CAD cutting system, and in the high-frequency hot pressing fixing process, the two fiber optic output ends are directly moved vertically downward by 12mm to accurately match the vertical offset of the acupoints caused by the user's anterior pelvic tilt.

[0036] The fiber optic output end maintains the standard configuration: Dachangshu is a deep physiotherapy acupoint, retaining the spherical microlens, and the beam expansion spot is maintained in the standard range of 8~15mm. The outer black silicone light-shielding gasket is assembled normally, still meeting the GB 7247.1 Class I laser light leakage safety requirements; the position of the SMA905 coupling interface of all fiber optic input ends remains unchanged to ensure the stability of the docking with the weak laser emission module at the bottom.

[0037] The optoelectronic and control systems remain unchanged: the embedded weak laser emission module maintains its IP67 waterproof rating, dual power-off protection with temperature control and voltage, NTC temperature measurement (55℃ threshold), MEMS optical switch time-division multiplexing, and other functions; the local signal control unit retains Bluetooth 5.2 + Wi-Fi 6 dual-channel communication, 256M storage, three-level permission partitioning, USB-C magnetic fast charging, and other configurations, and can freely switch between two working modes: user self-use and doctor remote prescription locking. The cloud APP's prescription push, log upload, and remote early warning functions are working normally.

[0038] This customized solution relies on mass production calibration processes to achieve one-time fit at the factory, eliminating the complex manual adjustment structure of traditional physiotherapy clothing. This not only reduces the probability of mechanical failure in the later stages, but also effectively solves the pain point that the national standard pattern cannot fit overweight or abnormal body shape people. The modified clothing retains all the core technical features of this invention, and the functions such as laser physiotherapy, safety protection, cloud control, and washability are not affected, which greatly expands the range of people to whom the product is applicable.

[0039] The embodiments described above are merely illustrative of several implementations of the present invention, and while the descriptions are specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements all fall within the scope of protection of the present invention. Therefore, the scope of protection of this patent should be determined by the appended claims.
