Description

Technical Field

[0001] This invention relates to the technical field of OLED red light, and more particularly to a hair-enhancing cap irradiated by OLED red light. Background Technology

[0002] Hair loss disorders such as androgenetic alopecia and alopecia areata are becoming increasingly common, significantly impacting personal image and mental health. Low-energy phototherapy (LLLT), as a non-invasive physical therapy, is widely used due to its safety and painlessness. Its mechanism of action is generally believed to be that photons of specific wavelengths (typically in the 630-670nm red light range) are absorbed by the mitochondria of hair follicle cells, promoting cytochrome C oxidase activity, thereby increasing the production of adenosine triphosphate (ATP), and activating hair follicles in the resting phase into the growth phase.

[0003] Currently, phototherapy hair regrowth devices on the market mainly fall into two categories: one is professional large-scale medical phototherapy instruments, which are expensive and require use in institutions, making them extremely inconvenient; the other is home-use hair regrowth caps, which mostly use light-emitting diodes (LEDs) as the light source. However, existing home-use products have many inherent defects: 1. Rigid light source, poor comfort and fit: LEDs are point light sources, usually soldered on rigid circuit boards, which makes the equipment heavy and hard. It cannot perfectly fit the complex curvature of the human head, causing a feeling of pressure and easily creating blind spots in the irradiation, affecting the treatment effect.

[0004] 2. Fixed treatment parameters and lack of specificity: Most products use preset fixed light intensity and time, which cannot be adjusted according to the different types, severity and physiological conditions of hair loss of users. The effect varies from person to person, and there is a risk of over-irradiation or insufficient dosage.

[0005] 3. Limited functionality and lack of feedback and interaction: Existing devices are merely "lighting" tools and cannot monitor the treatment process. Users have no way of knowing whether their scalp condition has improved or whether the treatment is effective, and it is also difficult for them to adhere to regular use, resulting in poor treatment compliance.

[0006] 4. Low level of intelligence: It cannot intelligently link with users' daily life scenarios (such as mobile and work) and does not have the ability to self-optimize by accumulating data.

[0007] Therefore, there is an urgent need in this field for a new type of phototherapy hair growth device that can overcome the above-mentioned defects and achieve comfortable fit, precise perception, intelligent control and personalized treatment. Summary of the Invention

[0008] The purpose of this invention is to provide a hair growth cap that uses OLED red light irradiation to solve the problems of poor comfort, fixed treatment parameters, lack of intelligent feedback and personalized treatment in the prior art.

[0009] To achieve the above objectives, the present invention adopts the following technical solution: An OLED red light-illuminating hair-enhancing cap includes a cap body and a plurality of flexible OLED light sources disposed inside the cap body, and further includes: The scalp condition sensing module is used to acquire physiological parameters that characterize scalp health. The intelligent control module is communicatively connected to the scalp state sensing module and the OLED flexible light source; The intelligent control module is configured as follows: Based on the physiological parameters obtained by the scalp condition sensing module, a personalized phototherapy plan is generated. According to the phototherapy scheme, at least one luminescence parameter of the OLED flexible light source is dynamically controlled to achieve differentiated irradiation of the scalp.

[0010] In a preferred embodiment of the present invention, the scalp state sensing module includes an optical imaging unit (5a), which is configured to acquire image data of the scalp region; the intelligent control module is further configured to: The image data is processed to identify target areas on the scalp, and the target areas include at least one of the following: a first type of area with hair follicle density lower than a first threshold, and a second type of area with epidermal redness and swelling higher than a second threshold; The OLED flexible light source is controlled to apply a different irradiation strategy to the first type of region and / or the second type of region than to other regions.

[0011] As a preferred embodiment of the present invention, the OLED flexible light source is divided into multiple independently controllable lighting zones, and the differentiated illumination includes: controlling the luminous intensity, illumination duration or working mode of the OLED flexible light source in at least one lighting zone to make it different from the other lighting zones.

[0012] As a preferred embodiment of the present invention, the scalp state sensing module includes a non-invasive blood oxygen detection unit (5b), which is configured to detect the blood oxygen saturation of the subcutaneous tissue of the scalp; the intelligent control module is further configured to adjust the wavelength or pulse frequency of the OLED flexible light source according to the blood oxygen saturation.

[0013] As a preferred embodiment of the present invention, the system further includes a user behavior perception module communicatively connected to the intelligent control module; the intelligent control module is further configured to: in response to the user behavior perception module detecting that the user changes from a static state to a moving state, automatically switch the OLED flexible light source from the treatment mode to the safety mode, wherein the brightness in the safety mode is lower than that in the treatment mode.

[0014] As a preferred embodiment of the present invention, the system further includes a haptic feedback module; the intelligent control module is further configured to trigger the haptic feedback module to generate a prompting vibration when switching to the safety mode.

[0015] As a preferred embodiment of the present invention, the system further includes a treatment compliance management module; the intelligent control module is further configured to: Record the duration and coverage of each phototherapy session; When the actual treatment parameters fail to meet the target of the phototherapy plan, a reminder message is sent to the user via the associated mobile terminal.

[0016] As a preferred embodiment of the present invention, the intelligent control module is configured to predict the treatment effect based on historical physiological parameter data and historical phototherapy data through a machine learning model, and optimize the subsequent phototherapy plan accordingly.

[0017] As a preferred embodiment of the present invention, the cap body is provided with a transparent treatment window, and the OLED flexible light source is disposed above or below the window; the optical imaging unit (5a) in the scalp state sensing module images the scalp through the transparent treatment window.

[0018] As a preferred embodiment of the present invention, the OLED flexible light source has a stacked structure, including at least two light-emitting layers that emit different peak wavelengths. The intelligent control module controls the opening and closing of each light-emitting layer or the brightness ratio to achieve phototherapy output of composite wavelengths.

[0019] The beneficial effects of this invention are: 1. Ultimate comfort and perfect fit: The flexible OLED surface light source replaces the rigid LED dot matrix. The light source itself is flexible and fits the head contour perfectly, eliminating pressure points and blind spots. It is lightweight and significantly improves wearing comfort, making it easy for users to use for a long time.

[0020] 2. Precise Sensing and Targeted Treatment: By integrating sensors such as optical imaging and near-infrared spectroscopy, the system can non-invasively and quantitatively assess hair follicle density, micro-inflammatory status (redness and swelling), and subcutaneous microcirculation (blood oxygenation) levels in different scalp areas. Based on this, the intelligent control module can, like "precision guidance," focus on strengthening irradiation in weak areas and adopt a gentler strategy for sensitive areas, achieving a treatment upgrade from "broad-based irradiation" to "precise targeting," greatly improving treatment efficiency and safety.

[0021] 3. Truly Personalized and Adaptive Treatment: The system abandons the "one-size-fits-all" approach, customizing phototherapy plans for each user and dynamically adjusting subsequent plans based on changes in scalp condition before and after each treatment. Furthermore, by introducing machine learning models, the system can continuously learn and optimize treatment plans based on historical data, making them increasingly precise and achieving personalized treatment with "growth potential."

[0022] 4. Intelligent Scene Adaptation and Safety Assurance: Through user behavior perception modules (such as motion sensors), the system can intelligently identify the user's state. When the user begins to move, it automatically switches to a low-brightness safety mode and provides tactile reminders, effectively avoiding accidents that may be caused by strong light interfering with vision. This extends the safety of the treatment scenario from static to dynamic, broadening the product's applicable boundaries.

[0023] 5. Treatment Visualization and Adherence Management: The system makes the previously "invisible" treatment process "visible." Users can intuitively view scalp health images, treatment parameter comparisons, and long-term efficacy trend charts through a mobile app, thereby obtaining strong positive feedback. Simultaneously, the system's adherence management function effectively helps users establish and maintain regular treatment habits through recording and reminders, fundamentally ensuring the final therapeutic effect.

[0024] 6. Technology Integration and System Innovation: This invention organically integrates flexible optoelectronics, multimodal sensing, edge computing, artificial intelligence and wireless communication technologies into a wearable device, forming a complete "perception-decision-execution-feedback" intelligent health closed-loop system, representing the forefront of home medical devices towards intelligent and personalized development.
