Description

Technical Field

[0001] This invention relates to the field of microneedle therapy technology, and more particularly to an introductory roller needle skin therapy device. Background Technology

[0002] With the development of skin care technology, minimally invasive or non-invasive physical delivery techniques have received much attention in recent years. Among them, transdermal drug delivery technology based on microneedle rollers has been widely used due to its significant effects. The core principle of this technology is to use densely packed micron-sized needles to open extremely small channels on the skin surface, temporarily disrupting the barrier function of the stratum corneum, thereby significantly improving the transdermal absorption rate of active ingredients (such as hyaluronic acid, vitamins, growth factors, etc.). Traditional microneedle rollers have been clinically proven to effectively improve wrinkles, scars, pigmentation, and skin laxity. At the same time, the mechanical stimulation of the roller or needles can also induce the skin's wound repair mechanism, stimulating the regeneration of collagen and elastin in the dermis, thereby achieving the goal of tightening the skin and increasing skin thickness.

[0003] Chinese Patent Application Publication No. CN114748782A discloses a microneedle roller-type skin therapy device, comprising: a shell, a neck support, a microneedle roller, a liquid filling device, a penetration enhancement module, and a control component. One end of the neck support is positioned at an opening at one end of the shell. The microneedle roller is rotatably mounted on the neck support and located outside the shell. The liquid filling device is used to hold and atomize the solution. The penetration enhancement module is used to promote the skin's absorption of the atomized solution. The control component is used to drive the liquid filling device to atomize the solution and control the operation of the penetration enhancement module. In use, the aforementioned microneedle roller-type skin therapy device with an integrated penetration enhancement module allows for easy and uniform spraying of the atomized nutrient solution by the built-in liquid filling device and control component, making it convenient and aesthetically pleasing to use. Simultaneously, the penetration enhancement module promotes the skin's absorption of the nutrient solution or therapy solution.

[0004] However, the existing technology has the following problems: the existing technology cannot make adaptive adjustments according to the actual skin condition during the roller needle operation, resulting in poor treatment accuracy. Summary of the Invention

[0005] Therefore, the present invention provides an introductory roller needle skin therapy device to overcome the problem of poor treatment accuracy caused by the inability to make adaptive adjustments according to the actual skin condition in the prior art.

[0006] To achieve the above objectives, the present invention provides an introductory roller needle skin therapy device, comprising:

[0007] The physiotherapy device body includes a grip shell, a bracket disposed on the top of the grip shell, and a microneedle roller detachably mounted to the bracket;

[0008] The information acquisition module is located at the front end of the physiotherapy device body and includes an illumination unit for emitting composite detection light containing multiple wavelengths to the target skin area and receiving signals from the skin, and an image acquisition unit for acquiring images of the skin surface in real time.

[0009] An information processing module, connected to the information acquisition module, is used to process and analyze the received signals to extract skin surface and subcutaneous feature information, determine the skin sensitivity index based on the feature information to automatically identify and classify skin regions, and obtain the skin redness and swelling area change curve and pore shrinkage rate over time based on the skin surface image to determine the evaluation value of the physiotherapy effect. The feature information includes the skin surface health condition, skin thickness, and subcutaneous tissue elasticity.

[0010] The control module, which is connected to the physiotherapy device body and the information processing module respectively, is used to determine and execute the physiotherapy strategy according to the skin area category, and to determine the qualification of the physiotherapy process according to the physiotherapy effect evaluation value. Under the condition of non-qualification, the first preset sensitivity index is reduced, or the reason for non-qualification is determined according to the change rate of pores as redness and swelling dissipate.

[0011] Furthermore, the skin sensitivity index is determined by the thickness of the skin and the elasticity of the subcutaneous tissue.

[0012] Furthermore, the process of classifying skin regions includes:

[0013] The skin sensitivity index was compared with the first preset sensitivity index and the second preset sensitivity index, respectively.

[0014] Based on the comparison results where the skin sensitivity index is less than the first preset sensitivity index, the skin area category is determined as a normal area;

[0015] The skin region is classified as a sensitive area based on the comparison results where the skin sensitivity index is greater than or equal to the first preset sensitivity index and less than the second preset sensitivity index.

[0016] Based on the comparison results where the skin sensitivity index is greater than or equal to the second preset sensitivity index, the skin area category is determined as a risk area.

[0017] Furthermore, treatment strategies are determined based on skin region categories, among which...

[0018] If the skin area is classified as a normal area, the treatment strategy is determined to be to perform a standard roller needle therapy procedure, which uses a first speed and a first force to perform the roller needle operation;

[0019] If the skin area is classified as a sensitive area, the treatment strategy is determined to be a gentle roller needle therapy program, which includes roller needle operation using a second speed and a second force;

[0020] If the skin area is classified as a risk zone, the treatment strategy is to generate an instruction to prohibit the use of the roller needle, and further determine the treatment strategy based on whether there is any damage to the skin.

[0021] Furthermore, the physiotherapy strategy is determined based on whether there is skin damage, among which,

[0022] If damage is present, the physical therapy strategy is to activate a dormant mode in the damaged area.

[0023] If no damage is found, the physiotherapy strategy is to initiate the non-invasive optical care mode.

[0024] Furthermore, the evaluation value of the physiotherapy effect is determined by the integral value of the curve of skin redness and swelling area changing over time and the pore shrinkage rate.

[0025] Furthermore, the control module determines the qualification of the physiotherapy process based on the physiotherapy effect evaluation value, wherein,

[0026] If the physiotherapy effect evaluation value is less than the first preset evaluation value, the physiotherapy process is deemed unqualified, and the first preset sensitivity index is reduced according to the difference between the first preset evaluation value and the physiotherapy effect evaluation value.

[0027] If the physiotherapy effect evaluation value is greater than or equal to the first preset evaluation value and less than the second preset evaluation value, the physiotherapy process is deemed unqualified, and the reason for the unqualification is determined based on the change rate of pores as redness and swelling dissipate.

[0028] If the physiotherapy effect evaluation value is greater than or equal to the second preset evaluation value, the physiotherapy process is deemed qualified.

[0029] Furthermore, the decrease in the first preset sensitivity index is positively correlated with the difference in physiotherapy effect, wherein the difference in physiotherapy effect is the difference between the first preset evaluation value and the physiotherapy effect evaluation value.

[0030] Furthermore, based on the condition that the pore change rate is greater than or equal to the preset change rate, the reason for non-compliance is determined to be that the physical therapy effect is not up to standard, and the first action force and the second action force are increased according to the difference between the pore change rate and the preset change rate.

[0031] Furthermore, several adjustment methods are provided for the first force and the second force, and each adjustment method has a different adjustment range for the force.

[0032] Compared with existing technologies, the advantages of this invention lie in its ability to acquire surface and subcutaneous feature information through an information acquisition module. Based on key parameters such as skin thickness and subcutaneous tissue elasticity, it intelligently divides the area into normal, sensitive, and risk zones, and automatically matches differentiated physiotherapy strategies to different areas. This effectively overcomes the operational limitations of traditional needle roller devices, allowing for comprehensive physiotherapy in normal areas, gentle treatment in sensitive areas, and intelligent avoidance or switching to non-invasive optical modes in risk zones. This significantly improves the overall safety and targeted nature of the treatment process.

[0033] Furthermore, this invention introduces a physiotherapy effect evaluation value as a pass / fail criterion and designs a parameter dynamic optimization logic based on the evaluation value. When the physiotherapy effect is not up to standard, the system can not only automatically lower the preset sensitivity index to optimize the area division, but also intelligently diagnose the root cause of the problem based on the change rate of pores as redness and swelling dissipate, thereby precisely adjusting key parameters such as the force of the roller needle to adapt to individual differences in users and dynamic changes in the skin, achieving an intelligent physiotherapy experience that becomes more and more precise with use.

[0034] Furthermore, through cross-validation and comprehensive analysis of multimodal data, the present invention enables the device to more reliably identify risk areas and more accurately assess the true physiological effects of physiotherapy, effectively improving the reliability of safe and effective physiotherapy under complex skin conditions.

[0039] To make the objectives and advantages of the present invention clearer, the present invention will be further described below with reference to embodiments; it should be understood that the specific embodiments described herein are merely for explaining the present invention and are not intended to limit the present invention.

[0040] Preferred embodiments of the present invention will now be described with reference to the accompanying drawings. Those skilled in the art should understand that these embodiments are merely illustrative of the technical principles of the present invention and are not intended to limit the scope of protection of the present invention.

[0041] It should be noted that the data in this embodiment are all derived from a comprehensive analysis and evaluation of historical test data and corresponding historical test results from the three months prior to this test. Those skilled in the art will understand that the determination of the above-mentioned parameters for any single item in this invention can be achieved by selecting the value with the highest percentage based on the data distribution as the preset standard parameter, using weighted summation to obtain the value as the preset standard parameter, substituting each historical data point into a specific formula and using the value obtained from that formula as the preset standard parameter, or other selection methods, as long as the invention can clearly define different specific situations in the single-item judgment process through the obtained values.

[0042] Please see Figures 1 to 4 The following are schematic diagrams of the module connections of the introductory roller needle skin physiotherapy device according to an embodiment of the present invention; flowcharts of determining the physiotherapy strategy based on the skin area category according to an embodiment of the present invention; flowcharts of further determining the physiotherapy strategy based on whether there is skin damage according to an embodiment of the present invention; and flowcharts of determining the qualification of the physiotherapy process based on the physiotherapy effect evaluation value according to an embodiment of the present invention.

[0043] The present invention provides an immersion-type roller needle skin therapy device, comprising:

[0044] The physiotherapy device body includes a grip shell, a bracket disposed on the top of the grip shell, and a microneedle roller detachably mounted to the bracket;

[0045] The information acquisition module is located at the front end of the physiotherapy device body and includes an illumination unit for emitting composite detection light containing multiple wavelengths to the target skin area and receiving signals from the skin, and an image acquisition unit for acquiring images of the skin surface in real time.

[0046] An information processing module, connected to the information acquisition module, is used to process and analyze the received signals to extract skin surface and subcutaneous feature information, determine the skin sensitivity index based on the feature information to automatically identify and classify skin regions, and obtain the skin redness and swelling area change curve and pore shrinkage rate over time based on the skin surface image to determine the evaluation value of the physiotherapy effect. The feature information includes the skin surface health condition, skin thickness, and subcutaneous tissue elasticity.

[0047] The control module, which is connected to the physiotherapy device body and the information processing module respectively, is used to determine and execute the physiotherapy strategy according to the skin area category, and to determine the qualification of the physiotherapy process according to the physiotherapy effect evaluation value. Under the condition of non-qualification, the first preset sensitivity index is reduced, or the reason for non-qualification is determined according to the change rate of pores as redness and swelling dissipate.

[0048] Specifically, the gripping housing is equipped with a miniature drive motor that provides rotational power to the microneedle roller.

[0049] Specifically, the physiotherapy device body uses 192 roller needles, and the lighting unit includes an infrared LED and a photodetector. The infrared LED is used to emit composite detection light containing multiple wavelengths, and the photodetector is used to receive the reflected spectrum signal from the skin.

[0050] Specifically, the thickness of the skin is calculated by emitting light from infrared LEDs at wavelengths of 1200 nm to 1600 nm. The difference in the penetration and absorption of light of different wavelengths in the water-rich dermal tissue is utilized, and the spectral data is analyzed by an algorithm model to calculate the thickness of the dermal layer of the skin. The algorithm model can be, for example, iterative inversion based on Monte Carlo simulation or a machine learning regression model trained with clinical data.

[0051] Specifically, the elasticity of subcutaneous tissue is assessed by analyzing the deformation amplitude and the time rate of the skin rebounding to its original state in the image sequence. The elasticity index of subcutaneous tissue is used to evaluate the elasticity of subcutaneous tissue. The larger the elasticity index, the greater the elasticity of subcutaneous tissue. The elasticity index is calculated as: residual depth after skin rebound and stabilization after the negative pressure is removed / maximum deformation depth × rebound time / rebound time threshold. In this embodiment of the invention, the rebound time threshold is 0.5s.

[0052] Specifically, the image acquisition unit includes an imaging module consisting of an image sensor and an optical macro lens, used to acquire serialized digital images of the skin surface in real time under standardized uniform illumination conditions. The information processing module performs image registration and color space analysis on the serialized images, automatically segments and quantifies the area of ​​skin redness and swelling by identifying specific color feature regions, and then plots the curve of the redness and swelling area changing over time.

[0053] Specifically, the health status of the skin surface determines whether there is any damage, including inflammatory acne, open wounds, active skin lesions, and unhealed sunburn. The information processing module determines the presence of damage by comparing the acquired skin surface images with an existing skin image database.

[0054] Specifically, the skin sensitivity index is determined by the skin thickness and the elasticity of the subcutaneous tissue. The skin sensitivity index = first weighting coefficient × skin thickness threshold / skin thickness + second weighting coefficient × skin elasticity index / elasticity index threshold. In this embodiment of the invention, the first weighting coefficient is 0.6, the skin thickness threshold is 1mm, the second weighting coefficient is 0.4, and the elasticity index threshold is 0.9. However, the above values ​​are not limited to these values, and those skilled in the art can adjust the above values ​​according to actual needs.

[0055] Specifically, the process of classifying skin regions includes:

[0056] The skin sensitivity index was compared with the first preset sensitivity index and the second preset sensitivity index, respectively.

[0057] Based on the comparison results where the skin sensitivity index is less than the first preset sensitivity index, the skin area category is determined as a normal area;

[0058] The skin region is classified as a sensitive area based on the comparison results where the skin sensitivity index is greater than or equal to the first preset sensitivity index and less than the second preset sensitivity index.

[0059] Based on the comparison results where the skin sensitivity index is greater than or equal to the second preset sensitivity index, the skin area category is determined as a risk area.

[0060] In this embodiment of the invention, the first preset sensitivity index is 0.75 and the second preset sensitivity index is 0.85. However, the above values ​​are not limited to these values, and those skilled in the art can adjust the above values ​​according to actual needs.

[0061] Specifically, the physiotherapy strategy is determined based on the skin area category. If the skin area category is a normal area, the physiotherapy strategy is determined to be to perform a standard roller needle physiotherapy program, in which the roller needle operation is performed using a first speed and a first force.

[0062] If the skin area is classified as a sensitive area, the treatment strategy is determined to be a gentle roller needle therapy program, which includes roller needle operation using a second speed and a second force;

[0063] If the skin area is classified as a risk zone, the treatment strategy is to generate an instruction to prohibit the use of the roller needle, and further determine the treatment strategy based on whether there is any damage to the skin.

[0064] In this embodiment of the invention, the first velocity ranges from 200 to 250 r / min, the first force ranges from 0.8 to 1.2 N, the second velocity ranges from 100 to 150 r / min, and the second force ranges from 0.3 to 0.6 N.

[0065] Specifically, the control module monitors and controls the rotation speed of the microneedle roller in real time through a Hall sensor integrated inside the drive motor, ensuring that it remains stable within the target speed range determined by the physiotherapy strategy; and monitors the vertical force acting on the skin surface in real time through a miniature pressure sensor integrated into the roller support.

[0066] Specifically, the imported needle roller skin therapy device of the present invention can be connected to a smartphone APP via Bluetooth or Wi-Fi to provide feedback on the therapy strategy to the user.

[0067] Specifically, the physiotherapy strategy is further determined based on whether there is skin damage. If there is damage, the physiotherapy strategy is to activate the dormant mode in the damaged area.

[0068] If no damage is found, the physiotherapy strategy is to initiate the non-invasive optical care mode.

[0069] Specifically, the sleep mode involves the control module immediately cutting off the power to the microneedle roller's motor when the device moves to the damaged area, causing it to automatically stop rotating. Simultaneously, it warns the user through tactile vibration or audio-visual cues, guiding the user to manually skip or avoid the area, thus preventing secondary damage to the injured site. The non-invasive optical care mode involves activating low-energy LED phototherapy of specific wavelengths around the damaged area. For example, red light at 630nm±10nm is used for anti-inflammation and promoting repair, or yellow light at 590nm±10nm is used to soothe sensitivity and reduce nerve excitability, improving skin condition through non-invasive physical therapy. In this embodiment, the red and yellow light are implemented using an LED light source module integrated at the front end of the device.

[0070] Specifically, the evaluation value of the physiotherapy effect is determined by the integral value of the curve of the change of skin redness and swelling area over time and the pore shrinkage rate. The evaluation value of the physiotherapy effect is calculated as follows: third weighting coefficient × integral threshold / integral value + fourth weighting coefficient × pore shrinkage rate / pore shrinkage rate threshold. In this embodiment of the invention, the third weighting coefficient is 0.4, the integral threshold is 150%·min, the fourth weighting coefficient is 0.6, and the pore shrinkage rate threshold is 10%. However, the above values ​​are not limited to these values, and those skilled in the art can adjust the above values ​​according to actual needs.

[0071] Specifically, the integral value of the curve showing the change in skin redness and swelling area over time reflects the skin's dynamic repair capacity. The integral value quantifies the total inflammatory load borne by the skin throughout the entire process from the end of physical therapy to recovery. The smaller the integral value, the faster the skin repairs, the better its tolerance, and the smaller the stress response caused by the physical therapy.

[0072] Specifically, the control module determines the qualification of the physiotherapy process based on the physiotherapy effect evaluation value. If the physiotherapy effect evaluation value is less than the first preset evaluation value, the physiotherapy process is determined to be unqualified, and the first preset sensitivity index is reduced based on the difference between the first preset evaluation value and the physiotherapy effect evaluation value.

[0073] If the physiotherapy effect evaluation value is greater than or equal to the first preset evaluation value and less than the second preset evaluation value, the physiotherapy process is deemed unqualified, and the reason for the unqualification is determined based on the change rate of pores as redness and swelling dissipate.

[0074] If the physiotherapy effect evaluation value is greater than or equal to the second preset evaluation value, the physiotherapy process is deemed qualified.

[0075] In this embodiment of the invention, the first preset evaluation value is 0.8 and the second preset evaluation value is 0.9. However, the above values ​​are not limited to these. Those skilled in the art can adjust the above values ​​according to actual needs.

[0076] Specifically, the reduction of the first preset sensitivity index is positively correlated with the difference in physiotherapy effect. If the difference in physiotherapy effect is less than the preset difference in physiotherapy effect, the first preset sensitivity index is reduced to the corresponding value using a first adjustment coefficient of 0.9.

[0077] If the difference in the physical therapy effect is greater than or equal to the preset difference in the physical therapy effect, then the first preset sensitivity index is reduced to the corresponding value using the second adjustment coefficient of 0.8;

[0078] Wherein, the difference in physiotherapy effect is the difference between the first preset evaluation value and the physiotherapy effect evaluation value. In this embodiment of the invention, the preset difference in physiotherapy effect is 0.05.

[0079] Specifically, based on the condition that the pore change rate is greater than or equal to a preset change rate, the reason for non-compliance is determined to be that the therapeutic effect is not up to standard, and the first and second application forces are increased according to the difference between the pore change rate and the preset change rate. In this embodiment of the invention, the preset change rate is 5%.

[0080] Specifically, the pore change rate is the rate of change in pores after the redness and swelling subside, used to determine whether the pore shrinkage was caused by the redness and swelling. If a significant pore change rate can still be observed after the redness and swelling subside, it proves that the pore shrinkage is a real and lasting effect produced by the skin's own collagen regeneration and structural remodeling after effective activation. Conversely, if the pore change rate is very low after the redness and swelling subside, it indicates that the previous shrinkage was mainly caused by temporary physical compression, and the long-term effect of the treatment is not satisfactory.

[0081] Specifically, several adjustment methods are provided for the first force and the second force, and each adjustment method has a different adjustment range for the force. If the difference in the rate of change is less than a preset difference in the rate of change, the first force and the second force are increased to the corresponding value using a first force adjustment coefficient of 1.2.

[0082] If the difference in rate of change is greater than or equal to the preset difference in rate of change, then the first force and the second force are increased to the corresponding values ​​using the second force adjustment coefficient of 1.5.

[0083] The rate of change difference is the difference between the pore rate of change and the preset rate of change.

[0084] In this embodiment of the invention, the preset rate of change difference is 2%, the initial first force is 0.8 N, and the initial second force is 0.3 N.

[0085] The technical solution of the present invention has been described above with reference to the preferred embodiments shown in the accompanying drawings. However, it will be readily understood by those skilled in the art that the scope of protection of the present invention is obviously not limited to these specific embodiments. Without departing from the principles of the present invention, those skilled in the art can make equivalent changes or substitutions to the relevant technical features, and the technical solutions after these changes or substitutions will all fall within the scope of protection of the present invention.

[0086] The above description is merely a preferred embodiment of the present invention and is not intended to limit the invention. Various modifications and variations can be made to the present invention by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.
