Description

Technical Field

[0001] The present invention belongs to the technical field of biomedical medical devices, and particularly relates to a photoelectric collaborative intervention corneal reshaping lens for improving myopia, which is a corneal reshaping lens for an in-built electronic device. Background Art

[0002] Currently, myopia has become one of the major challenges to global public health, and its prevalence among children and adolescents is rapidly rising. Research shows that the global prevalence of myopia among children and adolescents is about 30.5%, and it has increased significantly over the past 30 years, rising from about one-fourth to one-third today: during the period from 1990 to 2000, the global prevalence of myopia among children and adolescents was 24.3%; from 2001 to 2010, it reached 25.3%; from 2011 to 2019, it further increased to 29.7%; and during the period from 2020 to 2023, the myopia rate has risen sharply, with the myopia rate among adolescents as high as 54%. The corneal reshaping lens is an effective non-surgical vision correction method, especially suitable for myopic patients. Compared with laser surgery, the use of the corneal reshaping lens has lower risks, and once the wearing is stopped, the cornea will gradually return to its original state, with reversibility, and to a certain extent, it can slow down the development process of myopia in children and adolescents. However, the corneal reshaping lens also has some drawbacks. For example, it must be worn at night for a long time, which not only greatly increases the risk of infection for the wearer but also brings many discomforts. Therefore, it is of great significance to develop a photoelectric collaborative intervention corneal reshaping lens that can improve myopia in a short time. Summary of the Invention

[0003] The purpose of the present invention is to provide a photoelectric collaborative intervention corneal reshaping lens for improving myopia. The reshaping lens realizes the electromagnetic coupling between the receiving coil and the transmitting coil through the photoelectric collaborative intervention part composed of an outer ring metal coil and an inner ring metal coil, and further realizes the intervention of the light field and the electric field.

[0004] To achieve the above purpose, the present invention adopts the following technical solutions:

[0007] The internal receiving end is a wireless coil receiving layer, which includes an outer ring metal coil and an inner ring metal coil.

Among them, the first semi-ring metal coil forms a first matching circuit, and a third patch capacitor and a RED-LED are provided at one end of the first semi-ring metal coil.

A fourth patch capacitor and a patch rectifier are provided at the corresponding end of the second semi-ring metal coil and the RED-LED. The two ends of the fourth patch capacitor are respectively connected to the second semi-ring metal coil.

[0021] The technical solution of the present invention will be described in detail below with reference to the drawings and embodiments.

[0022] Example 1

[0023] As Figure 1 shown, an optoelectronic collaborative intervention orthokeratology lens for improving myopia provided in this embodiment includes an external transmitter, an internal receiver, and an orthokeratology lens, and the external transmitter and the internal receiver are interconnected by electromagnetic coupling.

[0024] The external transmitter includes a first metal coil layer, and a first patch capacitor and a second patch capacitor are provided on the first metal coil layer. The first patch capacitor is in series with the first metal coil, and the second patch capacitor is in parallel with the first metal coil, that is, one end of the first patch capacitor is connected to the metal coil, and the other end is connected to one end of the second patch capacitor. The other end of the second patch capacitor is connected to the wireless receiving coil layer. The external transmitter is integrated in the frame glasses, and the integrated structure is shown in Figure 3 .

[0025] The internal receiving end is a wireless coil receiving layer, which includes an outer ring metal coil and an inner ring metal coil. The outer ring metal coil is composed of a first semi-circular ring metal coil and a second semi-circular ring metal coil that do not touch each other. Among them, the first semi-circular ring metal coil constitutes a first matching circuit, and a third patch capacitor and a RED-LED are provided at one end of the first semi-circular ring metal coil. The third patch capacitor is in parallel with the first semi-circular ring metal coil, and the RED-LED is in parallel with the third patch capacitor, that is, the third patch capacitor is connected to the semi-circular ring metal coil; both ends of the RED-LED are respectively connected to the first semi-circular ring metal coil. The second semi-circular ring metal coil and the inner ring together constitute a second matching circuit; a fourth patch capacitor and a patch rectifier are provided at the corresponding end of the second semi-circular ring metal coil and the RED-LED. The fourth patch capacitor is in parallel with the second semi-circular ring metal coil, and the patch rectifier is in series with the second semi-circular ring metal coil, that is, both ends of the fourth patch capacitor are respectively connected to the second semi-circular ring metal coil, one end of the patch rectifier is connected to the second metal coil, and the other end is connected to one end of the fourth patch capacitor.

[0026] During implementation, the transmitting end and the receiving end form an electromagnetic coupling energy transmission system, and a magnetic field is generated through the transmitting coil. After the receiving coil senses the magnetic field, an alternating current is generated to supply power to the load to achieve LED lighting and electric field stimulation. When in use, between the external transmitting end and the internal receiving end, through the matching circuit, the resonant frequencies of the wireless receiving coil and the metal coil are both controlled at 44.5 MHZ, so that the transmitting coil and the receiving coil are mutually coupled, thereby realizing wireless LED lighting and generating an electric field for intervention. The optical side view of the internal receiving end is as shown in Figure 4 (a), and the front view of the internal receiving end during operation is as shown in Figure 4 (b).

[0027] For the above-mentioned optoelectronic collaborative intervention corneal reshaping lens for improving myopia, the preparation parameters of each component are as follows:

[0028] Prepare the external transmitting end. The external transmitting end is a transmitting resonant circuit, and this resonant circuit is a copper coil. The wire diameter of the single-turn copper wire coil is 0.25 mm, the coil diameter is 45 mm, and a 100 pF first series patch capacitor and a 10 nF second parallel patch capacitor are welded.

[0029] Prepare an internal receiver, where the internal receiver is a receiving resonant circuit, a first matching circuit and a second matching circuit of a wireless receiving coil layer. The wire diameter of the first matching circuit is 0.2 mm, and the loop diameter is 12 mm; it is provided with a 680 pF shunt third chip capacitor and a chip RED-LED lamp. The wire diameter of the second matching circuit is 0.2 mm, and the loop diameter is 12 mm. Among them, the outer loop diameter of the inner ring of the electric field intervention is 11 mm, and the inner loop diameter is 1 mm. The second matching circuit is provided with a 680 pF shunt fourth chip capacitor and a chip rectifier. The preparation of the first matching circuit and the second matching circuit can be realized by using the existing process.

[0030] To better illustrate the effect of the optoelectronic collaborative intervention orthokeratology lens for improving myopia in this embodiment, it is verified through Experiment 1 below. Experiment 1 is used to make a guinea pig myopia model and perform optoelectronic intervention treatment on the guinea pig myopia model with the optoelectronic collaborative intervention orthokeratology lens for improving myopia.

[0031] Experiment 1

[0032] Perform optoelectronic intervention treatment on the guinea pig myopia model using the device of Example 1, specifically as follows:

[0033] As Figure 5 shown, in order to induce a lens-induced myopia (LIM) model, guinea pigs were equipped with customized monocular rigid gas-permeable contact lenses with a refractive power set to -10 for a 2-week modeling period. As Figure 6 shown, the refractive powers of the left and right eyes of the LIM guinea pig model can both reach -2D, meeting the requirements of myopia. After the modeling was completed, the LIM guinea pig models were divided into 4 groups, with the number of guinea pigs in each group being n (n = 4), namely control group A, light intervention group B, electric field intervention group C, and optoelectronic intervention group D. Among them, control group A did not receive any treatment, and the myopia of the guinea pigs was alleviated less after seven days; in light intervention group B, light intervention was performed on the left and right eyes of the LIM guinea pigs simultaneously, and the refractive powers of the left and right eyes returned to the normal level after seven days; in electric field intervention group C, electric field intervention was performed on the right eye of the LIM guinea pigs, and the refractive power of the right eye returned to the normal level after seven days, and the myopia of the non-intervened left eye was alleviated less; in optoelectronic intervention group D, optoelectronic intervention was performed on the right eye of the LIM guinea pigs and light intervention was performed on the left eye. After seven days, the refractive power of the right eye returned to the normal level, and the myopia of the left eye with only light intervention was alleviated to a certain extent but was smaller than that of the optoelectronic intervention group.
