Description

Technical Field

[0001] The present invention relates to the technical field of myopia treatment, and in particular to an intelligent myopia treatment device. Background Art

[0002] Low-frequency electrical stimulation (LFES) is a widely used treatment in rehabilitation medicine, with a history dating back to 1700, when Dureney began physiological experiments using electric current to stimulate frog muscles. With the advancement of technology, LFES has been gradually applied to treat a variety of conditions, including pain management, neurological disorders, and muscle problems.

[0003] In the field of vision correction, low-frequency current stimulation is being used to develop an innovative myopia treatment device. This device, through a combination of intelligent hardware and software, delivers low-frequency pulses of current to the eye area. These pulses penetrate the epidermis around the eye, stimulating the ciliary muscle neurons and relaxing them. This, in turn, alleviates eye fatigue and improves the ciliary muscle's ability to adjust.

[0004] Clinical trials have proven that low-frequency electric pulse eye therapy devices can not only promote blood circulation around the eyes, relax eye muscles, relieve optic nerve fatigue and dry eyes, but also improve eye problems such as bags under the eyes and dark circles. For people with pseudomyopia, they can even recover to a healthy level after periodic therapy.

[0005] Chinese patent application publication number: CN118356589A discloses a myopia red light therapeutic device, comprising a housing, a light guide tube, a red light source, a light-transmitting lens, and a light-blocking structure. The light guide tube is disposed within the housing, the red light source is mounted on the housing, the light-transmitting lens is disposed on the housing, a through hole is disposed within the light guide tube, the red light emitted by the red light source can pass through the through hole and illuminate the light-transmitting lens, the light-blocking structure is blocked within the through hole, a light-transmitting hole is provided on the light-blocking structure, and the aperture of the light-transmitting hole can be adjusted, and the red light emitted from the red light source can pass through the light-transmitting hole. The myopia red light therapeutic device can adjust the intensity of the red light irradiated onto different eyes according to the patient's myopia condition, thereby improving the therapeutic effect.

[0006] It can be seen that the myopia red light therapy device has the following problems: although the myopia red light therapy device can adjust the red light intensity according to the patient's myopia condition to improve muscle response, the therapy device lacks monitoring of the patient's response during the treatment process and cannot adjust the treatment strategy in time, resulting in poor muscle response. Summary of the Invention

[0007] To this end, the present invention provides an intelligent myopia treatment device to overcome the problem in the prior art of lack of monitoring of the patient's response during treatment, inability to adjust the treatment strategy in a timely manner, and resulting in poor muscle response of pseudomyopia.

[0008] To achieve the above objectives, the present invention provides an intelligent myopia treatment device, comprising:

[0009] A host computer for generating a pulse current;

[0010] an electrotherapy component connected to the host, comprising an ear clip for stimulating the patient's ears with a pulsed current and a patch electrode for stimulating the patient's eyes with a pulsed current;

[0011] a data input module connected to the host computer and used to input the patient's myopia degree;

[0012] a data acquisition module connected to the electrotherapy assembly, comprising a resistance measurement component for acquiring skin resistance feedback from the electrotherapy assembly, and a signal acquisition component for acquiring electromyographic signals generated by the patient's muscle activity;

[0013] a data analysis module, connected to the data input module and the data acquisition module, respectively, for determining a treatment strategy based on the degree of myopia, determining the maximum intensity of the pulse current based on the skin resistance, establishing an electromyogram based on the electromyographic signal to determine the average absolute value of the amplitude of the electromyogram, and constructing a power spectrum density diagram and an instantaneous amplitude curve based on the electromyogram;

[0014] a data judgment module connected to the data analysis module, configured to determine whether the patient's muscle activity range is qualified based on the average absolute value, determine the optimal pulse current frequency based on the power spectrum density graph, and determine the eligibility of the muscle activity intensity based on the instantaneous amplitude curve;

[0015] The current control module is responsive to the determination result of the data judgment module to adjust the pulse width of the pulse current if it is determined that the patient's muscle activity range is unqualified, and to adjust the maximum intensity if it is determined that the muscle activity intensity is unqualified.

[0016] Furthermore, the data analysis module determines, based on the comparison result that the myopia degree is less than a preset degree, that the treatment strategy is to stimulate the ear area and the eye area in a sequential order.

[0017] Furthermore, the data analysis module determines that the treatment strategy is to stimulate the ear area and the eye area simultaneously based on the comparison result that the myopia degree is greater than or equal to the preset degree.

[0018] Furthermore, under the determined treatment strategy, the data analysis module determines that the maximum intensity of the pulse current is the first intensity based on the comparison result that the skin resistance is greater than the preset resistance value, and determines that the maximum intensity of the pulse current is the second intensity based on the comparison result that the skin resistance is less than or equal to the preset resistance value.

[0019] Furthermore, the data analysis module takes several points in the electromyogram whose absolute amplitude values ​​are greater than a preset absolute value as sampling points, counts the number of sampling points and calculates the sum of the absolute amplitude values ​​of each sampling point, and determines the ratio of the sum of the absolute amplitude values ​​to the number as the average absolute value.

[0020] Furthermore, the data judgment module determines that the patient's muscle activity range is unqualified based on the comparison result that the average absolute value is less than a preset average value.

[0021] Furthermore, the current control module calculates a first difference percentage between the average absolute value and the preset average value under the condition that it is determined that the patient's muscle activity range is unqualified, and determines to increase the pulse width by a first pulse width adjustment coefficient based on a comparison result that the first difference percentage is greater than a first preset percentage, and determines to increase the pulse width by a second pulse width adjustment coefficient based on a comparison result that the first difference percentage is less than or equal to the first preset percentage.

[0022] Furthermore, the data judgment module determines the pulse current frequency corresponding to the maximum power spectrum density value in the power spectrum density graph as the optimal current frequency under the condition that the patient's muscle activity range is determined to be unqualified.

[0023] Furthermore, the data analysis module connects several peaks in the electromyogram spectrum to establish an instantaneous amplitude curve, calculates the area enclosed by the instantaneous amplitude curve and the horizontal and vertical axes, and determines that the muscle activity intensity is unqualified based on the comparison result that the area is greater than the standard area.

[0024] Furthermore, the current control module calculates a second difference percentage between the area and the standard area under the condition that the muscle activity intensity is determined to be unqualified, and determines to increase the maximum intensity of the pulse current by the first intensity adjustment coefficient based on the comparison result that the second difference percentage is greater than the second preset percentage, and determines to increase the maximum intensity of the pulse current by the second intensity adjustment coefficient based on the comparison result that the second difference percentage is less than or equal to the second preset percentage.

[0025] Compared with the prior art, the beneficial effect of the present invention lies in that the present invention stimulates the patient's specific acupoints through ear clips clamped on the ears and patch electrodes attached to the eyes, regulates eye blood circulation and nerve function, thereby relieving eye fatigue and treating pseudomyopia; the treatment strategy is determined according to the patient's myopia degree. Under the condition of a certain treatment time, a high degree of myopia indicates a higher degree of ciliary muscle tension, and the ear acupoints and eye acupoints need to be stimulated simultaneously to achieve a better muscle response. A low degree of myopia indicates a lower degree of ciliary muscle tension. The ear acupoints can be stimulated first, and then the eye acupoints can be stimulated, which can achieve a better muscle response under milder conditions; the size of the pulse current is determined according to the patient's skin resistance. When the same intensity of current is used for stimulation, the muscle reaction with a larger skin resistance is weak, and the muscle reaction with a smaller skin resistance is strong. A better muscle response can be achieved without a higher intensity of current, thereby providing targeted treatment strategies according to the differences of the patients and improving the muscle response.

[0026] Furthermore, the present invention obtains the electromyogram spectrum during the treatment process in real time, and calculates the average absolute value based on the electromyogram spectrum. The amplitude of the electromyogram spectrum represents the amplitude of muscle movement when stimulated. Only when the amplitude is large can it be said that the muscle has been effectively stimulated and has given an effective response. Better muscle response can be achieved when the effective range of eye muscle activity is large enough. Therefore, the eligibility of the patient's muscle activity range can be judged according to the average absolute value, and whether the stimulation of the treatment device is effective can be determined. In the case of unqualified muscle activity range, the pulse width of the pulse current can be increased, thereby further improving the muscle response.

[0027] Furthermore, the present invention determines a power spectrum density diagram based on the electromyographic signal diagram. The power spectrum density represents the energy distribution of the signal within a specific frequency range. The larger the power spectrum density, the greater the intensity of the muscle activity, and the better the stimulation effect of the therapeutic device. The frequency corresponding to the maximum power spectrum density value is determined as the frequency of the pulse current, which further improves the muscle response based on the differences among patients.

[0028] Furthermore, the present invention determines the instantaneous peak curve based on the electromyographic signal graph, and compares the area enclosed by the instantaneous amplitude curve and the coordinate axis with the standard area to determine whether the effect of a single treatment is qualified. A large instantaneous amplitude indicates a large contraction intensity of the muscle and a high degree of tension in the ciliary muscle. Continuous tension and inability to relax the ciliary muscle will cause blurring when looking at distant objects, thereby aggravating the degree of myopia. Therefore, the muscle reaction can be determined according to the change in the instantaneous amplitude, thereby adjusting the parameters of the treatment process, and further improving the muscle reaction.

[0039] An embodiment of the present invention provides an intelligent myopia treatment device, comprising:

[0040] Host 1, which is used to generate pulse current;

[0041] An electrotherapy component connected to the host 1, comprising an ear clip 3 for stimulating the patient's ears with a pulse current and a patch electrode 2 for stimulating the patient's eyes with a pulse current;

[0042] A data input module, connected to the host 1, for inputting the patient's myopia degree;

[0043] a data acquisition module connected to the electrotherapy assembly, comprising a resistance measurement component for acquiring skin resistance feedback from the electrotherapy assembly, and a signal acquisition component for acquiring electromyographic signals generated by the patient's muscle activity;

[0044] a data analysis module, connected to the data input module and the data acquisition module, respectively, for determining a treatment strategy based on the degree of myopia, determining the intensity of the pulse current based on the skin resistance, establishing an electromyogram based on the electromyographic signal to determine the average absolute value of the amplitude of the electromyogram, and constructing a power spectrum density diagram and an instantaneous amplitude curve based on the electromyogram;

[0045] a data judgment module connected to the data analysis module, configured to determine whether the patient's muscle activity range is qualified based on the average absolute value, determine the optimal pulse current frequency based on the power spectrum density graph, and determine the eligibility of the muscle activity intensity based on the instantaneous amplitude curve;

[0046] A current control module, in response to the judgment result of the data judgment module, is used to adjust the pulse width of the pulse current when it is determined that the patient's muscle activity range is unqualified, and to adjust the intensity of the pulse current when it is determined that the muscle activity intensity is unqualified.

[0047] Specifically, pulse current refers to a current whose direction remains unchanged but whose intensity changes continuously within a certain range. The frequency range of the pulse current generated by the intelligent myopia treatment device in the embodiment of the present invention is 0-30Hz, the current intensity range is 0-50mA, and the pulse width range is 1-200ms. In actual applications, the pulse current generated by the treatment device has a fixed frequency and pulse width, and the current intensity changes continuously. The frequency is determined according to the power spectrum density diagram, the maximum intensity is determined according to the skin resistance, and the pulse width is the median value corresponding to the pulse width used for qualified muscle responses in historical treatment processes.

[0048] Specifically, the frequency of the pulse current refers to the number of times the pulse current repeats per unit time, and the pulse width refers to the length of time it takes for the pulse current to reach its maximum value (or a specific value) and end (or return to the specific value).

[0049] Specifically, the resistance measurement component and the signal acquisition component are both arranged on the patch electrode 2 to collect the electromyographic signals and skin resistance of the eyes. The tolerance of the ear skin is higher than that of the eye skin, so the degree of stimulation that the eye skin can accept is most likely acceptable to the ear skin. At the same time, the relief of vision is mainly to relieve the tension of the ciliary muscle. Therefore, it is only necessary to collect the skin resistance and electromyographic signals of the eyes to determine and adjust the parameters of the pulse current.

[0050] Specifically, the data analysis module determines, based on the comparison result that the myopia degree is less than the preset degree, that the treatment strategy is to stimulate the ear area first and then the eye area with the pulse current.

[0051] Specifically, the data analysis module determines that the treatment strategy is to stimulate the ear area and the eye area simultaneously with pulse current based on the comparison result that the myopia degree is greater than or equal to the preset degree.

[0052] Specifically, the degree of pseudomyopia is generally below 300 degrees, and the value range of the preset degree is set to [80 degrees, 200 degrees]. In the embodiment of the present invention, 150 degrees is preferred.

[0053] Specifically, under a determined treatment strategy, the data analysis module determines that the maximum intensity of the pulse current is the first intensity based on a comparison result that the skin resistance is greater than a preset resistance value, and determines that the maximum intensity of the pulse current is the second intensity based on a comparison result that the skin resistance is less than or equal to the preset resistance value.

[0054] Specifically, the value range of the preset resistance is set to [1kΩ, 10kΩ], and 5kΩ is preferred in the embodiment of the present invention; the value range of the first intensity is set to [16mA, 25mA], and 20mA is preferred in the embodiment of the present invention; the value range of the second intensity is set to [10mA, 15mA], and 13mA is preferred in the embodiment of the present invention.

[0055] Specifically, the greater the skin resistance, the greater the current intensity it can withstand.

[0056] Specifically, the data analysis module takes several points in the electromyogram whose absolute amplitude values ​​are greater than a preset absolute value as sampling points, counts the number of sampling points and calculates the sum of the absolute amplitude values ​​of each sampling point, and determines the ratio of the sum of the absolute amplitude values ​​to the number as the average absolute value.

[0057] Specifically, the preset absolute value is determined based on the absolute value of the amplitude of the electromyographic signal spectrum of qualified muscle responses during historical treatment processes, and the value range is set to [10 μV, 30 μV]. 15 μV is preferred in the embodiment of the present invention.

[0058] Specifically, a larger absolute value indicates a larger amplitude of muscle stimulation and a better muscle response.

[0059] Specifically, the data judgment module determines that the patient's muscle activity range is unqualified based on the comparison result that the average absolute value is less than a preset average value;

[0060] The data judgment module determines that the patient's muscle activity range is qualified based on the comparison result that the average absolute value is greater than or equal to the preset average value.

[0061] Specifically, the preset average value is the average of several average absolute values ​​of the historical treatment process.

[0062] Specifically, when the absolute values ​​are within a certain range, a larger average absolute value indicates a larger range of muscle activity.

[0063] Specifically, the current control module calculates a first difference percentage between the average absolute value and the preset average value under the condition that it is determined that the patient's muscle activity range is unqualified, and determines to increase the pulse width by a first pulse width adjustment coefficient based on a comparison result that the first difference percentage is greater than a first preset percentage; and determines to increase the pulse width by a second pulse width adjustment coefficient based on a comparison result that the first difference percentage is less than or equal to the first preset percentage.

[0064] Specifically, the value range of the first preset percentage is set to [5%, 40%], and 20% is preferred in the embodiment of the present invention; the value range of the first pulse width adjustment coefficient is set to [1.15, 1.24], and 1.2 is preferred in the embodiment of the present invention; the value range of the second pulse width adjustment coefficient is set to [1.04, 1.13], and 1.08 is preferred in the embodiment of the present invention.

[0065] Specifically, the pulse width adjustment coefficient is adjusted as follows: the product of the pulse width before adjustment and the adjustment coefficient is the pulse width after adjustment. For example, if the pulse width before adjustment is 100ms, and the first pulse width adjustment coefficient is used for adjustment, the pulse width after adjustment is 100ms×1.2=120ms.

[0066] Specifically, the data judgment module determines the pulse current frequency corresponding to the maximum power spectrum density value in the power spectrum density graph as the optimal current frequency under the condition that the patient's muscle activity range is determined to be unqualified.

[0067] Specifically, the process of obtaining the power spectrum density map is as follows:

[0068] Preprocessing the electromyographic signal, including but not limited to filtering, denoising and baseline correction;

[0069] Perform Fourier transform on the preprocessed EMG signal to convert the signal from time domain to frequency domain;

[0070] In the frequency domain, the power spectral density can be obtained by calculating the square of the modulus (or amplitude square) of the Fourier transform result and normalizing it appropriately;

[0071] The obtained power spectrum densities are used to draw a power spectrum density diagram with frequency as the horizontal axis and power spectrum density as the vertical axis.

[0072] Specifically, the power spectral density describes the power distribution of the signal at different frequencies, that is, the energy distribution of the signal at each frequency. The larger the power spectral density, the greater the degree of muscle stimulation.

[0073] Specifically, the data analysis module connects several peaks in the electromyogram spectrum to establish an instantaneous amplitude curve, calculates the area enclosed by the instantaneous amplitude curve and the coordinate axis, and determines that the muscle activity intensity is unqualified based on a comparison result that the area is greater than a standard area;

[0074] The muscle activity intensity is determined to be qualified based on the comparison result that the area is less than or equal to the standard area.

[0075] Specifically, the standard area is the area enclosed by the instantaneous standard amplitude curve and the coordinate axis, and the standard instantaneous amplitude curve is an instantaneous amplitude curve that indicates a qualified muscle response.

[0076] Specifically, the instantaneous amplitude reflects the instantaneous contraction strength of the muscle. Under the same stimulation conditions, the greater the instantaneous contraction strength of the ciliary muscle, the higher the tension of the ciliary muscle and the more severe the visual fatigue.

[0077] Specifically, when determining that the muscle activity intensity is unqualified, the current control module calculates the second difference percentage between the area and the standard area, and determines to increase the intensity of the pulse current by the first intensity adjustment coefficient based on the comparison result that the second difference percentage is greater than the second preset percentage, and determines to increase the intensity of the pulse current by the second intensity adjustment coefficient based on the comparison result that the second difference percentage is less than or equal to the second preset percentage.

[0078] Specifically, the value range of the second preset percentage is set to [5%, 10%], and 8% is preferred in the embodiment of the present invention; the value range of the first intensity adjustment coefficient is set to [1.05, 1.08], and 1.06 is preferred in the embodiment of the present invention; the value range of the second intensity adjustment coefficient is set to [1.02, 1.04], and 1.03 is preferred in the embodiment of the present invention.

[0079] Specifically, the intensity adjustment coefficient is adjusted as follows: the product of the maximum intensity before adjustment and the adjustment coefficient is the maximum intensity after adjustment. For example, if the maximum intensity before adjustment is 20mA, the first intensity adjustment coefficient is used for adjustment, and the maximum intensity after adjustment is 20mA×1.06=21.2mA.

[0080] Specifically, the intensity of the pulse current varies within a certain range, so only the maximum intensity needs to be adjusted.

[0082] 1. A total of 100 patients (200 eyes) with moderate to high myopia and myopia in adolescents who visited the Department of Ophthalmology of Shenyang Fenglaitang Traditional Chinese Medicine Hospital from January 2023 to August 2023 were selected as the research samples, of which 50 patients (100 eyes) were high myopia and 50 patients (100 eyes) were myopic adolescents, that is, 50 patients (100 eyes) with high myopia and 50 patients (100 eyes) with myopia. The treatment time was from August 2023 to November 2023. All patients were divided into two groups using a digital random table, 50 cases (100 eyes) in the observation group and 50 cases (100 eyes) in the control group. Among them, there were 33 males (66 eyes) and 17 females (34 eyes) in the observation group, with an average age of (12.05±4.37) years old. The observation group and control group included 25 patients (50 eyes) with high myopia and 25 patients (50 eyes) with myopia, respectively. The control group consisted of 30 males (60 eyes) and 20 females (40 eyes), with a mean age of (11.59±5.03) years. There was no statistically significant difference in general information between the two groups (P>0.05), indicating that the two groups were comparable.

[0083] 2. The control group received frame glasses. They were fitted with frame glasses based on medical optometry results and were instructed to wear them regularly for three months. The observation group received a myopia treatment device, which uses pulsed current applied to acupuncture points and then reaches the eye tissue through the meridians to relax the eye muscles, thereby relieving visual fatigue. Treatment was administered twice daily, lasting 20 minutes each time. Ten sessions constituted a course of treatment, with a two-day interval between courses. After three courses, treatment was adjusted to once a week for a total of three months.

[0084] 3. For single treatment: (1) Take the data of a single patient as an example: a myopia degree of 125 degrees is input into the myopia treatment device, and the myopia treatment device determines that the treatment strategy for the patient is that the pulse current first stimulates the ear area and then stimulates the eye area; then the patient's skin resistance is determined by the resistance measurement component, which is 3kΩ, which is less than the preset degree 5kΩ, and the maximum intensity of the pulse current is determined to be 13mA; while the pulse current stimulates the patient's acupuncture points, the muscle activity electrical signal of the patient's ciliary muscle is recorded and an electromyogram is drawn. The average absolute value calculated based on the amplitude of the electromyogram is 20μV, which is greater than the preset absolute value of 15μV, and the muscle activity range is determined to be qualified, and continuous treatment is performed in the current state until the end of the treatment.

[0085] (2) Take the data of a single patient as an example: a myopia degree of 200 degrees is input into the myopia treatment device, and the myopia treatment device determines that the treatment strategy for the patient is to stimulate the ear area and the eye area with a pulse current at the same time; then the skin resistance of the patient is determined by the resistance measurement component, which is 7kΩ, which is greater than the preset degree of 5kΩ, and the maximum intensity of the pulse current is determined to be 20mA; while the pulse current stimulates the patient's acupoints, the muscle activity electrical signal of the patient's ciliary muscle is recorded and an electromyogram is drawn. The average absolute value calculated based on the amplitude of the electromyogram is 12μV, which is less than the preset absolute value of 15μV, and the patient is determined to have a myopia degree of 200 degrees. The patient's muscle activity range is unqualified, and the pulse current frequency corresponding to the maximum power spectral density value is determined to be the optimal current frequency; under the condition that the first difference percentage is determined to be 20%, which is equal to the first preset percentage, the pulse width is adjusted with a second pulse width adjustment coefficient of 1.08, and the patient is continuously treated with the optimal current frequency and the adjusted pulse width as parameters of the pulse current, and the electromyogram is drawn again based on the muscle activity electrical signal to calculate the average absolute value of 15μV, which is equal to the preset absolute value to determine that the muscle activity range is qualified, and the patient is treated with the adjusted pulse current parameters until the end of the single treatment.
