Description

Technical Field

[0001] The invention belongs to the technical field of spraying medicine, and in particular to a spraying control method and system for treating chloasma. Background Art

[0002] Melasma, also known as liver spots, is a common pigmentation skin disease, which is mainly manifested by symmetrical brown patches on the facial skin, usually on the cheeks, forehead and chin. This symptom not only affects the patient's appearance, but may also lead to a decrease in self-confidence and increased psychological pressure, especially in women. The causes of chloasma are complex and may be closely related to multiple factors such as ultraviolet radiation, changes in hormone levels, genetic factors, drug side effects and environmental factors.

[0003] At present, traditional methods for treating melasma mainly include topical medication, laser therapy and physical therapy. Although topical medications such as whitening agents containing hydroquinone, amoxicillin, vitamin C and other ingredients can reduce pigmentation to a certain extent, their effects often vary from individual to individual. At the same time, some drugs may be accompanied by irritation and side effects during use, making it difficult for patients to persist in using them. Although laser treatment has a more significant therapeutic effect, it is expensive, requires professional equipment and operation, and may have risks of postoperative recovery period and skin sensitivity. In terms of the application of spray preparations, traditional treatment sprays often adopt a "one-size-fits-all" approach, that is, a fixed concentration of spray preparations is used regardless of the patient's specific situation. This method lacks personalized treatment and cannot effectively respond to changes in the patient's skin condition, resulting in limitations in the treatment effect. In addition, the spraying efficiency of traditional spray equipment has not been effectively monitored, and problems such as drug waste and poor uniformity may occur, which is not conducive to improving the treatment effect.

[0037] See also Figure 2 The embodiment of the present invention provides a spray control method for treating chloasma, which may include the following steps:

[0038] S201, performing real-time spectral analysis on a skin area affected by chloasma to obtain spectral reflectance data of the skin area;

[0039] In this step, detailed spectral reflectance data is collected for the skin area affected by melasma through real-time spectral analysis technology. The core of this process is to use a spectral instrument to analyze the spectrum reflected by the skin and obtain the intensity and wavelength data of the reflected light for subsequent analysis of the characteristic bands of melasma. This method relies on the reflection characteristics of different wavelengths of light on different components of the skin to achieve accurate identification and evaluation of skin spots.

[0040] Specifically, a spectrometer that covers the visible and near-infrared spectral ranges (e.g., 400nm to 800nm) can be selected. The device should have high resolution and fast response capabilities to ensure that high-quality data is obtained in a short time. Ensure that the skin area is clean before analysis to avoid interference from external dirt and cosmetics to improve the accuracy of the spectral reflectance data. Physiological saline can be used to gently clean the area to be tested. Aim the spectrometer at the skin area to be tested, and ensure that the detector of the spectrometer is at an appropriate distance from the skin surface (e.g., 1-2 cm) to avoid interference from light reflection. Start the spectrometer for multiple sampling to ensure that sufficient spectral data is obtained (it is recommended to obtain at least 100 measurements, with an interval of 1 second between each measurement) to reduce the impact of random noise. De-noise the collected spectral reflectance data, including smoothing the data using methods such as polynomial fitting and moving average to remove errors introduced by environmental interference or equipment noise.

[0041] Spectral analysis can be used to conduct in-depth analysis of skin areas in the spectral dimension, identify the characteristic bands of chloasma, and provide a scientific basis for subsequent treatment; the spectral reflectance data acquired in real time can reflect the immediate state of the skin, so that the treatment plan can be dynamically adjusted based on specific data to enhance the effect of personalized treatment; through real-time monitoring and feedback, it can help doctors or treatment equipment to understand the progress of treatment in a timely manner, thereby adjusting the spraying strategy and improving the success rate of chloasma treatment; a quantitative indicator system is provided to accumulate data for future research and clinical applications, and promote the advancement of chloasma treatment technology.

[0042] S202, performing discrete Fourier transform processing on the spectral reflectance data, extracting the characteristic band of chloasma, and calculating the chloasma intensity index;

[0043] In this step, the spectral reflectance data obtained in the previous step is processed by discrete Fourier transform (DFT). Discrete Fourier transform is a mathematical tool that converts time domain signals into frequency domain signals, which can effectively extract the frequency components in the signal. Through DFT processing, characteristic bands related to melasma in spectral data can be identified, and these bands usually show significant reflectance changes in certain specific spectral ranges. This change is mainly related to the distribution and concentration of pigments in the skin, reflecting the presence and intensity of melasma. After extracting the characteristic bands, the melasma intensity index (MCI) is calculated based on the data of these bands. This index provides a quantitative basis for subsequent treatment decisions. The melasma intensity index comprehensively considers the reflectance information of each characteristic band and can accurately reflect the severity of melasma.

[0044] Specifically, a calculation formula for the chloasma intensity index may be:

[0045]

[0046] Wherein, the MCI is the chloasma intensity index, which reflects the chloasma intensity in a specific skin area and is an important basis for clinical treatment decision-making. The higher the value, the more obvious the chloasma and the more urgent the need for treatment. The R (lambda_i) is the skin reflectance at the wavelength lambda_i of the characteristic band of chloasma, which is a specific value obtained by spectral analysis. The magnitude of the reflectance is related to the pigment concentration in the skin and directly reflects the severity of chloasma. The Weight_i is the corresponding weight coefficient, indicating the contribution of each band to the final result when calculating the chloasma intensity index. The reflection characteristics of different bands may be different, so it is necessary to adjust them through the weight coefficient to highlight those bands that are closely related to the intensity of chloasma. The n is the total number of wavelengths.

[0047] The formula obtains a comprehensive value to characterize the intensity of melasma by weighted summation of the reflectance of characteristic bands. The core of designing this formula is to adjust the reflectance of different wavelengths through weight coefficients in order to highlight the band that has the greatest impact on the intensity of melasma.

[0048] By performing DFT processing on spectral reflectance data and extracting characteristic bands, the presence and intensity of melasma can be quantified into a numerical index, providing a scientific basis for subsequent evaluation of treatment effects; DFT technology effectively transforms the original spectral data, allowing those potential characteristic bands that are difficult to directly observe to appear, thereby improving the accuracy of chloasma judgment and avoiding interference from subjective factors; the calculated chloasma intensity index can reflect changes in the patient's skin condition in real time, so that the treatment plan can be dynamically adjusted according to the patient's actual situation, thereby improving the treatment effect; this step can establish a correlation model between chloasma and spectral characteristics, provide a new research direction, and help to deeply understand the formation mechanism of chloasma and its relationship with other skin diseases.

[0049] S203, dynamically adjusting the concentration of the spray preparation for treating chloasma according to the chloasma intensity index;

[0050] In this step, the concentration of the spray preparation used to treat melasma is dynamically adjusted based on the calculated melasma intensity index (MCI). The core of this process is based on real-time feedback from the patient's current skin condition. The severity of melasma is determined by the MCI value, thereby achieving a personalized spray plan. Specifically, when the MCI value is higher than a predetermined threshold, it means that the severity of melasma is high and the concentration of the spray preparation needs to be increased to enhance the treatment effect; otherwise, the spray concentration can be appropriately reduced to avoid excessive use of the drug or unnecessary irritation to the skin. This dynamic adjustment mechanism ensures the flexibility and targeting of the treatment, so that each patient's treatment plan can be optimized according to their immediate condition.

[0051] Specifically, a method for adjusting the concentration of the spray preparation may be:

[0052] C_adjusted=C_base+k·(MCI-MCI_threshold)

[0053] Among them, the C_adjusted is the adjusted concentration of the spray preparation, which reflects the drug concentration required under the current skin condition to ensure the accuracy of the treatment. The C_base is the current concentration of the spray preparation, which serves as the reference value for adjustment and provides a starting point for dynamic adjustment to ensure that each treatment has a reasonable initial concentration. The MCI_threshold is the critical MCI value, which sets a baseline to determine whether the current chloasma intensity exceeds the normal range. The setting of this value should be reasonably selected based on clinical observations and data analysis results in order to effectively distinguish different degrees of chloasma. The k is the concentration adjustment coefficient, and k is a positive number that controls the sensitivity of the MCI change to the spray concentration adjustment. By adjusting the value of k, the system's sensitivity to changes in chloasma intensity can be adjusted, thereby achieving personalized treatment.

[0054] By reflecting the intensity of chloasma on the patient's skin in real time, the treatment plan can be customized according to individual differences to enhance the effectiveness of the treatment; dynamic adjustment of the concentration of the spray preparation can ensure that the drug exerts the best therapeutic effect at the appropriate concentration, enhance the therapeutic effect on chloasma, and reduce the risk of recurrence; appropriate regulation of the spray concentration can effectively reduce irritation to normal skin and prevent skin discomfort or other side effects caused by excessive concentration; a closed-loop control system with real-time feedback has been established, which can continuously optimize the spraying strategy during the treatment process to ensure efficient and safe treatment.

[0055] S204, injecting the spray preparation after adjusting the concentration into the spray equipment in real time, and calculating the current spraying efficiency index of the spray equipment;

[0056] In this step, the spray preparation with adjusted concentration will be injected into the spray equipment in real time for the treatment of melasma. At the same time, the current spray efficiency index (SEI) of the spray equipment is calculated, which is used to evaluate the performance of the spray equipment during the spraying process.

[0057] The current spray efficiency index can reflect the spray effect of the spray by analyzing multiple parameters of the spray equipment (such as spray pressure, spray angle and spray particle size, etc.). By calculating the SEI, medical personnel can understand the distribution of the spray preparation during actual use and ensure that the drug can be evenly and effectively covered in the affected skin area.

[0058] Specifically, a calculation formula for the current spraying efficiency index may be:

[0059]

[0060] Among them, the SEI is the current spraying efficiency index, which is a quantitative indicator that reflects the effect and efficiency of drug spraying of the spray equipment under specific conditions, which is convenient for subsequent optimization and comparison. The P is the spray pressure, which directly affects the spraying ability of the spray. A higher spray pressure usually leads to a longer spraying distance and increases the coverage area. The theta is the spraying angle, which refers to the angle between the spray equipment and the skin surface. Optimizing the spraying angle can make the drug more evenly distributed on the skin surface, thereby improving the spraying effect. The right angle helps to avoid concentrated spraying of the drug in a specific area. The D is the spray particle size, which affects the ability of the drug to deposit on the skin. A smaller particle size usually means that the drug can penetrate deeper into the skin, but it may cause the drug to float in the air longer, reducing the deposition efficiency. On the contrary, although a larger particle size can be deposited quickly, it may affect the uniform distribution of the drug.

[0061] This formula quantifies the spraying efficiency of the spray equipment through multiple key parameters. The design principle is to combine the influence of pressure, spray angle and particle size through the principles of physics to clarify the contribution of each factor to the spraying effect. Specifically, the spray pressure P and the spray angle theta affect the coverage and uniformity of the spray, while the spray particle size D affects the deposition efficiency of the drug on the skin surface.

[0062] SEI provides medical personnel with a method to quantify the spraying effect, which can intuitively understand whether the spray equipment is working in the best condition. This evaluation ensures that the drug can fully reach the melasma area; by calculating SEI, medical personnel can dynamically adjust the spray equipment parameters (such as spray pressure, spray angle, etc.), further optimize the spray configuration, and maximize the treatment effect; by monitoring the spraying efficiency, problems with the spray equipment can be discovered in time, such as uneven spraying or insufficient pressure, so as to take corresponding measures to prevent treatment failure or drug waste; good spraying efficiency can ensure the comfort of patients during treatment, reduce the discomfort caused by uneven spraying or insufficient concentration, and improve patients' trust in treatment.

[0063] S205, adjusting the spray parameters of the spray device according to the current spray efficiency index, and using the adjusted spray device to spray the spray preparation with adjusted concentration on the skin area.

[0064] Adjust the parameters of the spraying device according to the current Spraying Efficiency Index (SEI) obtained from the previous step. This process aims to optimize the performance of the spraying device, enabling it to maximize drug coverage while ensuring the uniformity and effectiveness of the spraying process. By dynamically adjusting the spraying parameters (such as spraying pressure, spraying angle, and spraying distance), it is possible to better adapt to the characteristics of the skin area to be treated and the spraying requirements, thereby achieving the best treatment effect. After the adjustment is completed, the spraying device will use the spray preparation with the adjusted concentration to perform the spraying treatment for melasma. This process forms a closed-loop feedback system that can continuously update and optimize the treatment plan based on real-time monitoring data.

[0065] Specifically, dynamic analysis can be implemented based on the current SEI value. For example:

[0066] If SEI < SEI_{threshold} (the preset SEI threshold), it indicates insufficient spraying efficiency. The spraying pressure P can be increased, the spraying angle theta can be adjusted (for example, from 45 degrees to 30 degrees), and at the same time, the spray particle size D can be reduced as needed to enhance the atomization effect until SEI reaches the threshold.

[0067] If SEI > SEI_{threshold}, it indicates excessive spraying efficiency. The spraying pressure P can be reduced, the spraying angle theta can be appropriately increased (for example, from 45 degrees to 60 degrees), and at the same time, the spray particle size D can be moderately increased to reduce the spraying intensity until SEI reaches the threshold.

[0068] Start spraying the spray preparation with the adjusted concentration using the adjusted spraying device. During the spraying process, continuously monitor the performance of the spraying device to ensure that the drug is evenly covered on the affected skin area. After spraying, regularly evaluate the skin reaction and record the treatment results to analyze the effectiveness of the spraying control method and make improvements to future treatment plans. By implementing the above steps, an efficient and intelligent spraying control system can be formed, significantly improving the treatment effect of melasma and ensuring the scientific and personalized nature of the treatment.

[0069] It can be seen that real-time spectral analysis is performed on the skin area affected by chloasma to obtain spectral reflectance data of the skin area; discrete Fourier transform processing is performed on the spectral reflectance data to extract the characteristic band of chloasma, and the chloasma intensity index is calculated; according to the chloasma intensity index, the concentration of the spray preparation used to treat chloasma is dynamically adjusted; the spray preparation with adjusted concentration is injected into the spray equipment in real time, and the current spray efficiency index of the spray equipment is calculated; according to the current spray efficiency index, the spray parameters of the spray equipment are adjusted, and the adjusted spray equipment is used to spray the spray preparation with adjusted concentration on the skin area, so that modern spectral analysis technology can be used to monitor the characteristic band of chloasma in real time, dynamically adjust the concentration of the spray preparation, and optimize the spray efficiency in real time to achieve better treatment effects.
