Description

Technical Field

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

[0002] As a treatment measure widely adopted in the field of rehabilitation medicine, the application history of low-frequency electrical stimulation can be traced back to 1700, when Dureney began physiological experiments on stimulating frog muscles with electric current. With the development of technology, low-frequency electrical stimulation has gradually been applied to the treatment of various diseases, including pain management, neurological diseases, and muscle problems.

[0003] In the field of vision correction, low-frequency electrical current stimulation has been used to develop an innovative myopia treatment device. This device combines intelligent hardware and software to emit low-frequency pulsed current to the eye perimeter. These low-frequency pulsed currents can penetrate the epidermal layer of the eye perimeter, stimulate the ciliary muscle neurons of the eye, relax the muscles, and thus improve eye fatigue and enhance the adjustment ability of the ciliary muscle.

[0004] Verified through clinical trials, the low-frequency electrical pulse eye physiotherapy instrument can not only promote blood circulation in the eye perimeter, relax the eye muscles, relieve optic nerve fatigue and dry eye syndrome, but also improve eye perimeter problems such as eye bags and dark circles. For people with pseudomyopia, through periodic physiotherapy, they can even recover to a healthy level.

[0005] Chinese Patent Application Publication No.: CN118356589A discloses a myopia red light therapy instrument, which includes a housing, a light guide tube, a red light light source, a light-transmitting lens, and a light-blocking structure. The light guide tube is arranged inside the housing, the red light light source is installed on the housing, the light-transmitting lens is arranged on the housing, a through hole is arranged inside the light guide tube, the red light emitted by the red light light source can pass through the through hole and irradiate on the light-transmitting lens, the light-blocking structure blocks the through hole, a light-transmitting hole is arranged on the light-blocking structure, and the size of the aperture of the light-transmitting hole can be adjusted, and the red light emitted from the red light light source can pass through the light-transmitting hole. This myopia red light therapy instrument can adjust the light intensity of the red light irradiated on different eyes according to the myopia condition of the patient, thereby improving the treatment effect.

[0006] It can be seen that the myopia red light therapy instrument has the following problems: Although the myopia red light therapy instrument can adjust the light intensity of the red light according to the myopia condition of the patient to improve the muscle response, the instrument lacks monitoring of the patient's reaction during the treatment process and cannot adjust the treatment strategy in a timely manner, 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 that the reaction of the patient during the treatment process lacks monitoring, and the treatment strategy cannot be adjusted in time, resulting in poor muscle response to pseudomyopia.

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

[0009] A main unit, which is used to generate pulsed current;

[0010] An electrotherapy component, which is connected to the main unit, and includes ear clips for stimulating the patient's ear with pulsed current and patch electrodes for stimulating the patient's eye with pulsed current;

[0011] A data input module, which is connected to the main unit and is used to input the patient's myopia degree;

[0012] A data acquisition module, which is connected to the electrotherapy component, and includes a resistance measurement component for collecting the skin resistance value feedback by the electrotherapy component and a signal acquisition component for collecting the electromyographic signal generated by the patient's muscle activity;

[0013] A data analysis module, which is respectively connected to the data input module and the data acquisition module, and is used to determine the treatment strategy according to the myopia degree, determine the maximum intensity of the pulsed current according to the skin resistance value, establish an electromyogram to determine the average absolute value of the amplitude of the electromyogram according to the electromyographic signal, and construct a power spectral density diagram and an instantaneous amplitude curve according to the electromyogram;

[0014] A data judgment module, which is connected to the data analysis module, and is used to determine whether the muscle activity range of the patient is qualified based on the average absolute value, determine the optimal pulsed current frequency based on the power spectral density diagram, and determine the qualification of the muscle activity intensity based on the instantaneous amplitude curve;

[0015] A current control module, which responds to the determination result of the data judgment module, and is used to adjust the pulse width of the pulsed current under the condition that the muscle activity range of the patient is determined to be unqualified, and adjust the maximum intensity under the condition that the muscle activity intensity is determined to be unqualified.

[0016] Further, the data analysis module determines the treatment strategy to stimulate the ear area and the stimulated eye area in sequence according to the comparison result that the myopia degree is less than the preset degree.

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

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

[0019] Further, the data analysis module uses several points in the electromyogram spectrum whose absolute amplitude values are greater than the preset absolute value as sampling points, counts the number of sampling points, 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] Further, the data judgment module determines that the muscle activity range of the patient is unqualified based on the comparison result that the average absolute value is less than the preset average value.

[0021] Further, under the condition that the data judgment module determines that the muscle activity range of the patient is unqualified, the current control module calculates the first difference percentage between the average absolute value and the preset average value, and determines to increase the pulse width with the first pulse width adjustment coefficient based on the comparison result that the first difference percentage is greater than the first preset percentage, and determines to increase the pulse width with the second pulse width adjustment coefficient based on the comparison result that the first difference percentage is less than or equal to the first preset percentage.

[0022] Further, under the condition that the data judgment module determines that the muscle activity range of the patient is unqualified, the pulse current frequency corresponding to the maximum power spectral density value in the power spectral density map is determined as the optimal current frequency.

[0023] Further, 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 coordinate 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] Further, under the condition that the current control module determines 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 maximum intensity of the pulsed current with 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 pulsed current with 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 an ear clip clamped on the ear and a patch electrode attached to the eye, regulates the eye blood circulation and nerve function, thereby relieving eye fatigue and treating pseudomyopia; determines the treatment strategy 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 requires simultaneous enhanced stimulation of the ear acupoints and the eye acupoints to achieve a better muscle response, and a low degree of myopia indicates a lower degree of ciliary muscle tension, and the ear acupoints can be stimulated first, and then the eye acupoints can be stimulated, so as to achieve a better muscle response under milder conditions; determines the size of the pulse current according to the patient's skin resistance, and when the same intensity of current is used for stimulation, the muscle reaction of the muscle with a larger skin resistance is weak, and the muscle reaction of the muscle with a smaller skin resistance is strong, and a better muscle reaction can be achieved without a higher intensity of current, thereby providing targeted treatment strategies according to the differences of patients and improving muscle reaction.

[0026] Furthermore, the present invention obtains the electromyogram spectrum in real time during the treatment process, 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 determined based on the average absolute value, and it can be determined whether the stimulation of the treatment device is effective. 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 according to 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 of 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, including:

[0040] A main unit 1 for generating pulsed current;

[0041] An electrotherapy component connected to the main unit 1, including an ear clip 3 for stimulating the patient's ear with pulsed current and a patch electrode 2 for stimulating the patient's eye with pulsed current;

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

[0043] A data acquisition module connected to the electrotherapy component, including a resistance measurement component for collecting the skin resistance value feedback by the electrotherapy component and a signal acquisition component for collecting the electromyographic signal 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 according to the myopia degree, determining the intensity of the pulsed current according to the skin resistance value, establishing an electromyogram to determine the average absolute value of the amplitude of the electromyogram according to the electromyographic signal, and constructing a power spectral density map and an instantaneous amplitude curve according to the electromyogram;

[0045] A data judgment module connected to the data analysis module for determining whether the muscle activity range of the patient is qualified based on the average absolute value, determining the optimal pulsed current frequency based on the power spectral density map, and determining the qualification 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, for adjusting the pulse width of the pulsed current under the condition that the muscle activity range of the patient is determined to be unqualified, and adjusting the intensity of the pulsed current under the condition that the muscle activity intensity is determined to be unqualified.

[0047] Specifically, the pulsed current refers to a current with a constant direction and a continuously changing intensity within a certain range. The frequency range of the pulsed current generated by the intelligent myopia treatment device in the embodiment of the present invention is 0 - 30 Hz, the current intensity range is 0 - 50 mA, and the pulse width range is 1 - 200 ms. In actual application, the pulsed current generated by the treatment device has a fixed frequency and pulse width, the current intensity changes continuously, the frequency is determined according to the power spectral density map, 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 response in the historical treatment process.

[0048] Specifically, the frequency of the pulsed current refers to the number of times the pulsed current repeats per unit time, and the pulse width refers to the time length from the start of the pulsed current reaching the maximum value (or a certain specific value) to the end (or returning to the specific value).

[0049] Specifically, both the resistance measurement component and the signal acquisition component are arranged on the patch electrode 2 to collect the electromyographic signal and skin resistance value of the eye. The tolerance of the ear skin is higher than that of the eye skin. Therefore, the degree of stimulation that the eye skin can accept can probably be accepted by the ear skin. At the same time, the relief of vision mainly relieves the tension of the ciliary muscle. Therefore, it is only necessary to collect the skin resistance value and electromyographic signal of the eye to determine and adjust the parameters of the pulsed current.

[0050] Specifically, the data analysis module determines the treatment strategy according to the comparison result that the myopia degree is less than the preset degree, that is, the pulsed current first stimulates the ear area and then stimulates the eye area.

[0051] Specifically, the data analysis module determines the treatment strategy according to the comparison result that the myopia degree is greater than or equal to the preset degree, that is, the pulsed current stimulates the ear area and the eye area simultaneously.

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

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

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

[0055] Specifically, the larger the skin resistance value, the greater the current intensity that can be tolerated.

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

[0057] Specifically, the value of the preset absolute value is determined according to the absolute wave amplitude of the electromyographic signal spectrum with qualified muscle responses in the historical treatment process, and the value range is set to [10 μV, 30 μV], and 15 μV is preferably selected in the embodiment of the present invention.

[0058] Specifically, the larger the absolute value, the greater the amplitude of the muscle movement stimulated and the better the muscle response.

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

[0060] The data judgment module determines that the muscle activity range of the patient 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 taken as the average of several average absolute values in the historical treatment process.

[0062] Specifically, when the absolute value is within a certain range, the larger the average absolute value, the larger the range of muscle activity.

[0063] Specifically, under the condition that the data judgment module determines that the muscle activity range of the patient is unqualified, the data judgment module calculates a first difference percentage between the average absolute value and the preset average value, determines to increase the pulse width with a first pulse width adjustment coefficient based on the comparison result that the first difference percentage is greater than a first preset percentage, and determines to increase the pulse width with a second pulse width adjustment coefficient based on the 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 preferably 20% in the embodiments of the present invention; the value range of the first pulse width adjustment coefficient is set to [1.15, 1.24], and preferably 1.2 in the embodiments of the present invention; the value range of the second pulse width adjustment coefficient is set to [1.04, 1.13], and preferably 1.08 in the embodiments of the present invention.

[0065] Specifically, the adjustment method of the pulse width adjustment coefficient is: 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 100 ms and it is adjusted with the first pulse width adjustment coefficient, the pulse width after adjustment is 100 ms × 1.2 = 120 ms.

[0066] Specifically, under the condition that the data judgment module determines that the muscle activity range of the patient is unqualified, the data judgment module determines the optimal current frequency as the pulse current frequency corresponding to the maximum power spectral density value in the power spectral density map.

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

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

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

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

[0071] Use the obtained power spectral densities to plot a power spectral density graph with frequency as the horizontal axis and power spectral 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 greater 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 axes, and determines that the muscle activity intensity is unqualified based on the comparison result that the area is greater than the standard area;

[0074] Determine that the muscle activity intensity is 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 axes, and the standard instantaneous amplitude curve is the instantaneous amplitude curve of qualified muscle response.

[0076] Specifically, the instantaneous amplitude reflects the instantaneous contraction intensity of the muscle. Under the condition of the same stimulation, the greater the instantaneous contraction intensity of the ciliary muscle, the higher the degree of tension of the ciliary muscle and the more serious the visual fatigue.

[0077] Specifically, under the condition that the muscle activity intensity is determined to be 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 pulsed current with a 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 pulsed current with a 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 preferably 8% in the embodiments of the present invention; the value range of the first intensity adjustment coefficient is set to [1.05, 1.08], and preferably 1.06 in the embodiments of the present invention; the value range of the second intensity adjustment coefficient is set to [1.02, 1.04], and preferably 1.03 in the embodiments of the present invention.

[0079] Specifically, the adjustment method of the intensity adjustment coefficient is 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 20 mA and it is adjusted using the first intensity adjustment coefficient, the maximum intensity after adjustment is 20 mA × 1.06 = 21.2 mA.

[0080] Specifically, the intensity of the pulsed current is constantly changing within a certain range, so only the maximum intensity needs to be adjusted.

[0081] Example

[0082] 1. A total of 100 myopic patients with moderate to high myopia and myopic adolescents who visited the ophthalmology department of Shenyang Fenglai Hall Traditional Chinese Medicine Hospital from January 2023 to August 2023 were selected as research samples. Among them, there were 50 cases (100 eyes) of high myopia and 50 cases (100 eyes) of myopic adolescents, that is, 50 cases (100 eyes) of high myopia and 50 cases (100 eyes) of myopia. The treatment time was from August 2023 to November 2023. All patients were divided into two groups using a random number table, with 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. There were 25 cases (50 eyes) of high myopia and 25 cases (50 eyes) of myopia in both the observation group and the control group. There were 30 males (60 eyes) and 20 females (40 eyes) in the control group, with an average age of (11.59 ± 5.03) years. There was no significant difference in the general data of the two groups of patients (P > 0.05), and they were comparable.

[0083] 2. The control group was treated with frame glasses. Frame glasses were dispensed according to the results of medical optometry, and regular wearing of glasses was required for 3 months after dispensing; the observation group was treated with a myopia treatment device. Pulsed current was used to act on acupoints and reach the eye tissues through the meridians to relax the eye muscles, thereby relieving visual fatigue. It was administered 2 times a day, 20 minutes each time, and 10 times was one course of treatment. There was a 2-day interval between two courses of treatment. After 3 courses of treatment, it was adjusted to once a week, and the total course of treatment was 3 months.

[0084] 3. For single treatment: (1) Taking the data of a single patient as an example: Input the myopia degree of 125 degrees into the myopia treatment device. The myopia treatment device determines that the treatment strategy for this patient is to first stimulate the ear area with pulsed current and then stimulate the eye area. Then, through the resistance measurement component, the skin resistance value of the patient is determined to be 3 kΩ, which is less than the preset value of 5 kΩ. Then, the maximum intensity of the pulsed current is determined to be 13 mA. While the pulsed current stimulates the patient's acupoints, the muscle activity electrical signals of the patient's ciliary muscle are recorded and an electromyogram is plotted. According to the amplitude of the electromyogram, the average absolute value is calculated to be 20 μV, which is greater than the preset absolute value of 15 μV. It is determined that the muscle activity range is qualified, and continuous treatment is carried out in the current state until the treatment ends.

[0085] (2) Taking the data of a single patient as an example: Input the myopia degree of 200 degrees into the myopia treatment device. The myopia treatment device determines that the treatment strategy for this patient is to stimulate the ear area and the eye area simultaneously with pulsed current. Then, through the resistance measurement component, the skin resistance value of the patient is determined to be 7 kΩ, which is greater than the preset value of 5 kΩ. Then, the maximum intensity of the pulsed current is determined to be 20 mA. While the pulsed current stimulates the patient's acupoints, the muscle activity electrical signals of the patient's ciliary muscle are recorded and an electromyogram is plotted. According to the amplitude of the electromyogram, the average absolute value is calculated to be 12 μV, which is less than the preset absolute value of 15 μV. It is determined that the muscle activity range of the patient is unqualified, and the optimal current frequency is determined according to the pulsed current frequency corresponding to the maximum power spectral density value. Under the condition that the first difference percentage is determined to be 20%, which is equal to the first preset percentage, it is determined to adjust the pulse width with the second pulse width adjustment coefficient of 1.08. The patient is continuously treated with the optimal current frequency and the adjusted pulse width as the parameters of the pulsed current. Then, an electromyogram is plotted again according to the muscle activity electrical signals, and the average absolute value is calculated to be 15 μV, which is equal to the preset absolute value. It is determined that the muscle activity range is qualified, and the patient is treated with the adjusted pulsed current parameters until the single treatment ends.
