Description

Technical Field

[0001] The present invention relates to the technical field of intense pulsed light therapy, and specifically to a light output adjustment method and an intense pulsed light therapy instrument. Background Art

[0002] Intense pulsed light (IPL) is a broad-spectrum light formed by focusing and filtering a light source with very high intensity. Its essence is an incoherent light. When applying IPL therapy, the principle of selective photothermolysis is used, which can effectively treat a variety of skin diseases and has a very important position in the field of skin beauty. It is mainly used to improve skin pigmentation, treat vascular dilation, improve wrinkles and skin relaxation, reduce pore size and improve oily skin, etc.

[0003] Currently, the most widely used IPL products on the market consist of a main unit and a handle. Before treatment, the therapist sets the treatment parameters according to experience or referring to the manufacturer's treatment parameter guide card, and then conducts the treatment; during treatment, the therapist holds the handle and conducts the treatment on the patient's skin. Due to the uneven treatment experience and level of therapists in each hospital or institution, and the differences in the judgment of diseases and skin colors, etc., the treatment parameters set by them vary greatly in terms of treatment effects; in addition, when the therapist holds the handle for treatment, since the IPL handle is heavier than the handles of other products and the treatment will last for a certain period of time, after the entire treatment course, the therapist's arm is quite tired.

[0004] The treatment techniques are divided into the stamping type and the sliding type. Among them, during the sliding type treatment, it is necessary to set the light output frequency, and then hold the handle and slide it on the skin to automatically emit light for treatment according to the set frequency. It highly tests the matching of the sliding speed of the therapist holding the handle with the light output frequency. Otherwise, when the sliding speed is too fast, some skin areas will be missed during treatment, and when the sliding speed is too slow, the same skin area will be treated repeatedly. Summary of the Invention

[0005] Based on this, in view of the problem of uneven treatment existing in the existing fixed-frequency sliding treatment of IPL handles, it is necessary to provide a light output adjustment method and an intense pulsed light therapy instrument.

[0006] To achieve the above object, the present invention adopts the following technical solutions:

[0007] A light output adjustment method includes the following steps:

[0008] Obtain the treatment filter category corresponding to the skin disease and the preset light energy;

[0009] Real-time collect the two-dimensional displacement increments DELTA_X i 、DELTA_Y i of the instrument sliding on the skin surface, and perform displacement accumulation on them to obtain the cumulative displacement S total ;

[0010] The cumulative displacement S total When the trigger condition is reached, the cumulative displacement is reset and the output is triggered as the real-time light emission frequency; wherein, the trigger condition is the product of the preset spot width size and the height coefficient, and the height coefficient characterizes the relationship between the output displacement of the instrument data acquisition point and the actual instrument displacement amount;

[0011] Collect the light energy at the real-time light emission frequency, fit it with the preset light energy, calculate the calibration coefficient, and adjust the light energy according to the calibration coefficient, so that the instrument uses the treatment filter category corresponding to the skin disease and works according to the adjusted light energy and the real-time light emission frequency.

[0012] Further, the specific steps for obtaining the treatment filter category corresponding to the skin disease and the preset light energy are as follows:

[0013] Collect skin photos taken under white light, polarized light and UV light;

[0014] Perform image processing on the skin photos taken to obtain the parameter values of the skin detection indicators, compare them with the normal values to determine the skin disease, and obtain the treatment filter category corresponding to the skin disease and the preset light energy.

[0015] Further, the skin detection indicators include at least one of skin color, skin texture, sensitivity, skin pigment, pores, porphyrin, telangiectasia, hair follicles, and spots.

[0016] The present invention also relates to an intense pulsed light therapeutic apparatus, including a main body and a skin detection module, a weight reduction bracket and a treatment handle communicatively connected to the main body, and the treatment handle is suspended on the weight reduction bracket; the treatment handle is internally provided with a frequency conversion kit for obtaining the sliding parameters of the treatment handle; the main body is also communicatively connected to an energy calibration module for measuring the actual light output.

[0017] The main body is used to obtain the treatment filter category corresponding to the skin disease and the preset light energy; it is also used to obtain the displacement increment of the treatment handle sliding on the skin surface for displacement accumulation, and is also used to reset the cumulative displacement and trigger the output as the real-time light emission frequency when the cumulative displacement reaches the trigger condition; wherein, the trigger condition is the product of the preset spot width size and the height coefficient, and the height coefficient characterizes the relationship between the calibrated displacement value output by the frequency conversion kit and the actual handle displacement amount; it is also used to obtain the actual light energy at the real-time light emission frequency, fit it with the preset light energy, calculate the calibration coefficient, and adjust the light energy according to the calibration coefficient, so that the treatment handle uses the treatment filter category corresponding to the skin disease and works according to the adjusted light energy and the real-time light emission frequency.

[0018] Further, the weight reduction bracket includes a bracket main body, a weight reduction motor and a weight reduction rope; the weight reduction rope is wound around the output shaft reel of the weight reduction motor, and the weight reduction motor is installed on the bracket main body and communicatively connected to the main body.

[0019] Further, the host is used to convert a preset force value for weight reduction into a current value for driving a weight reduction motor, and then drive the weight reduction motor to perform the operation of winding and unwinding the rope.

[0020] Further, the set light energy is N, where N≥1 and N is a positive integer.

[0021] Further, the fitting formula for fitting the actual light energy with the preset light energy is as follows:

[0022] E actual = a·E set + b;

[0023] Wherein, E actual represents the actual light energy, E set represents the preset light energy, and a and b are calibration coefficients.

[0024] The present invention also relates to a computer terminal, which includes a memory, a processor, and a computer program stored on the memory and executable on the processor. When the processor executes the program, the steps of the light output adjustment method as described above are implemented.

[0025] The present invention also relates to a computer-readable storage medium, on which a computer program is stored. When the program is executed by a processor, the steps of the light output adjustment method as described above are implemented.

[0036] It is easy to understand that according to the technical solution of the present invention, without changing the essence of the present invention, those of ordinary skill in the art can propose various structural ways and implementation ways that can be mutually replaced. Therefore, the following specific embodiments and the accompanying drawings are only exemplary descriptions of the technical solution of the present invention, and should not be regarded as all of the present invention or as a limitation or restriction on the technical solution of the present invention.

[0037] Embodiment 1

[0038] Please refer to Figure 1 , this embodiment introduces a light output adjustment method, which is mainly used for the sliding light output adjustment of an intense pulsed light treatment instrument. The method includes the following steps:

[0039] Step 1: Obtain the treatment filter category corresponding to the skin disease and the preset light energy.

[0040] Specifically, collect skin photos taken under white light, polarized light, and UV light; perform image processing on the skin photos to obtain the parameter values of skin detection indicators, compare them with normal values to determine the skin disease, and obtain the treatment filter category corresponding to the skin disease and the preset light energy.

[0041] Among them, during image processing, preprocessing operations such as noise suppression, color gamut conversion, and multi-modal fusion can be performed first, and then feature extraction can be performed through texture analysis of epidermal layer parameters, extraction of vascular networks of dermal layer parameters, etc., to obtain the parameter values of skin detection indicators. The skin detection indicators include at least one of skin color, skin texture, sensitivity, skin pigmentation, pores, porphyrin, telangiectasia, hair follicles, and spots.

[0042] Compare the parameter values obtained from the processing and analysis with the normal skin values, analyze the corresponding skin diseases, and recommend treatment parameters according to the skin diseases, such as the light energy for treatment, i.e., the preset light energy. In addition, the penetration depth of light with different wavelengths is different. Therefore, for different skin diseases, different wavelength filter plates should be selected, and thus the appropriate treatment filter plate category will also be recommended according to the skin diseases.

[0043] Step 2: Real-time collect the two-dimensional displacement increments DELTA_X i and DELTA_Y i of the instrument sliding on the skin surface, and perform displacement accumulation on them to obtain the cumulative displacement S total ;

[0044] Step 3: When the cumulative displacement S total reaches the trigger condition, reset the cumulative displacement and trigger the output as the real-time light emission frequency; among them, the trigger condition is the product of the preset spot width size and the height coefficient, and the height coefficient characterizes the relationship between the output displacement of the instrument data acquisition point and the actual displacement of the instrument.

[0045] The calculation process of steps 2 and 3 for the real-time light emission frequency is specifically as follows:

[0046] 1. Read the displacement increment:

[0047] DFLTA_X i , DELTA_Y i ←Sensor.read()

[0048] 2. Calculate the displacement accumulation:

[0049]

[0050] Among them, DELTA_S i represents the instantaneous displacement.

[0051] 3. Trigger condition:

[0052] When S total ≥k·H0, trigger the output and reset the cumulative displacement (retain the remainder), that is:

[0053] S total ←S total -k·H0

[0054] It should be noted that when the instrument is working, the treatment handle slides and fits the skin, and the sliding speed of the treatment handle is collected using the optical principle of the variable frequency kit, that is, the optical flow sensor, and the speed and direction of the object movement are calculated by comparing the pixel displacements between adjacent frames. Therefore, DELTA_X i actually represents the displacement in the x direction of the output adjacent frames, and DELTA_Yi It represents the displacement of the adjacent frames of the sensor output in the Y direction; k is used to calibrate the relationship between the displacement value output by the sensor and the actual displacement of the handle.

[0055] Step 4: Collect the light energy at the real-time light output frequency, fit it with the preset light energy, calculate the calibration coefficient, and adjust the light energy according to the calibration coefficient, so that the instrument uses the treatment filter category corresponding to the skin disease and operates according to the adjusted light energy and the real-time light output frequency. Specifically as follows:

[0056] To avoid the influence of the handle energy attenuation on the treatment effect, N light energies can be set, where N≥1 and is a positive integer. By comparing the actual light energy with the preset light energy, the correction coefficient is calculated to correct the light energy.

[0057] Select N set energy points to emit light, and for each set energy E set,i , use the sensor to measure the actual output energy E actual,i .

[0058] The fitting calibration formula is:

[0059] E actual = a·E set + b

[0060] where a and b are calibration coefficients:

[0061]

[0062] In this embodiment, by identifying the sliding parameters during the sliding treatment, the real-time light output frequency of the handle is further controlled to ensure uniform full coverage of the treatment area, which is beneficial to ensuring the curative effect; in addition, the light output energy can be corrected to ensure the accuracy of the light output energy.

[0063] Embodiment 2

[0064] As Figure 2 shown, this embodiment introduces a intense pulsed light therapeutic instrument, which mainly includes a host and a skin detection module, a weight reduction bracket and a treatment handle that are communicatively connected to the main body. The treatment handle is suspended on the weight reduction bracket; the treatment handle is internally provided with a frequency conversion kit for obtaining the sliding parameters of the treatment handle; the main body is also communicatively connected to an energy calibration module for measuring the actual light output amount.

[0065] Target tissues in the skin, such as melanin, hemoglobin, etc., will have strong absorption of irradiation at specific wavelengths or bands, thereby increasing the temperature; IPL mainly uses its principle of selective photothermal action for treatment; the penetration depths of lights with different wavelengths are different. Therefore, for different skin diseases, filters with different wavelengths should be selected.

[0066] The skin detection module can use existing instruments such as skin detectors. The therapist can use the skin detector to detect the skin condition of the treatment area and then recommend the type of filter and treatment parameters to ensure the effectiveness of the treatment. Figure 3 As shown, this is the workflow of the skin detector:

[0067] The skin detector is mainly used to take photos under white light, polarized light and UV light, perform image processing on the skin photos, obtain parameter values ​​of skin detection indicators, output skin detection indicators and symptoms, and recommend treatment filters and treatment parameters. The treatment parameters include light energy. When using an intense pulsed light therapy device, the recommended light energy can be used as the preset light energy.

[0068] The weight-reducing bracket includes a bracket body, a weight-reducing motor and a weight-reducing rope; the weight-reducing rope is wound on the output shaft reel of the weight-reducing motor, and the weight-reducing motor is installed on the bracket body and communicated with the host. The weight-reducing force value is set, and the host automatically converts the force value into a current value for the weight-reducing motor, thereby providing a weight-reducing force for the treatment handle, and also drives the weight-reducing motor to reel in and release the weight-reducing rope.

[0069] like Figure 4 The figure shows the workflow of the frequency conversion kit. If the frequency conversion mode is used, it can be set according to the recommended treatment parameters. The displacement is identified when the treatment handle slides. The host calculates the light output frequency through the sliding displacement and the spot width and controls the treatment handle to work according to the light output frequency.

[0070] The workflow of the energy calibration module is as follows: Figure 5 As shown, according to the requirements, the handle is used to align the light receiving port of the energy calibration module. The energy calibration module measures the actual light energy and analyzes and calculates the energy attenuation coefficient as the calibration coefficient to calibrate the energy of the light so that the error between the actual light energy and the set value is smaller.

[0071] The adjustment method of the host is in accordance with the light output adjustment method introduced in Example 1.

[0072] Working process:

[0073] After the product is turned on, the therapist first uses the skin detector to take pictures of the patient's treatment area and automatically analyze the relevant parameters of the skin. The system determines the disease based on the skin parameters and recommends the corresponding filter model and treatment parameters for the treatment; then the treatment handle is used for treatment. During the treatment, the treatment handle can be hung on the weight-reducing bracket for use. Stamp-type or sliding-type treatment can be used. During sliding treatment, the therapist can choose fixed frequency mode or variable frequency mode. When using the variable frequency mode for treatment, the frequency conversion kit automatically identifies the movement parameters of the handle and feeds the movement parameters back to the host. The host calculates and controls the light frequency.

[0074] In this embodiment, through a skin detector, a therapist can detect the skin condition of the treatment area through the skin detector, and then recommend the type of filter and treatment parameters to ensure the treatment effect. The variable frequency kit can identify the moving speed during sliding treatment, and then control the light emission frequency of the handle to ensure uniform full coverage of the treatment area, which is conducive to ensuring the treatment effect. The product is equipped with a weight reduction bracket. During treatment, the handle is suspended on the weight reduction rope, and the force value of weight reduction is set, allowing the therapist to operate the treatment handle with a smaller holding force to reduce the operation load and improve the therapist's operation experience.

[0075] In addition, after the device has been used for a certain period of time, the light emission energy of the handle will decay, resulting in too large a deviation between the actual light emission energy and the energy set value, affecting the treatment effect. By calibrating the light energy of the handle through the energy calibration module, not only can the accuracy of the light emission energy be ensured, but also the actual life status of the handle can be judged. According to the size of the calibration coefficient, its attenuation situation can be judged, and then the service life situation of the handle can be judged.

For example, it can be designed as an independently running program and installed on a computer terminal, which can be a computer, a smart phone, etc. It can also be designed as an embedded running program and installed on a computer terminal, such as installed on a single-chip microcomputer.
