Description

Technical Field

[0001] This invention relates to the field of phototherapy technology, specifically to a phototherapy device with adjustable therapeutic intensity. Background Technology

[0002] The phototherapy device integrates beneficial red light (wavelengths between 630-650 nanometers) from natural light to replace natural light, irradiating the retina with safe power and effective duration. This stimulates the retina to produce and release more dopamine, inhibiting axial elongation and thus controlling myopia progression. Through the device's beam, the choroid in the posterior pole of the eye thickens, scleral fiber elasticity is restored, and the retina secretes dopamine, effectively controlling axial length and thus preventing the occurrence and progression of myopia.

[0003] When red light acts on our choroid, the oxygen permeability and oxygen absorption capacity of the choroidal blood vessels increase, and the blood flow in the blood vessels also increases. After a series of increases, the thickness of the choroid changes. The increase in blood flow to the choroid and the change in thickness effectively improve the hypoxia symptoms of the retina and sclera.

[0004] Current phototherapy devices generally do not allow for adjustable treatment intensity, making it difficult to meet the needs of myopia patients with different degrees of myopia. Their use has certain limitations. More importantly, when the intensity is high and the usage time is long, it may lead to fundus lesions, macular degeneration, and other potential side effects, such as cataracts caused by long-term exposure to the lens.

[0040] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0041] Please see Figure 1-12 The present invention provides the following technical solution:

[0042] This embodiment provides a phototherapy device with adjustable therapeutic intensity, including: a bottom support assembly 1, a red light generating assembly 2, a lens assembly 3, and a control unit 4.

[0043] The bottom support component 1 is used to form the mounting base for the adjustable treatment intensity phototherapy device;

[0044] Among them, the red light generating component 2 is used to generate red light;

[0045] Among them, the lens tube assembly 3 is used to propagate the red light generated by the red light generating assembly 2;

[0046] The control unit 4 is used to control the operation of the red light generating component 2.

[0047] An adjustable phototherapy device employing the above-mentioned technical solution comprises a bottom support assembly 1, a red light generating assembly 2, a lens tube assembly 3, and a control unit 4. The red light generating assembly 2 generates red light with a wavelength between 630-650 nanometers. This red light with a wavelength between 630-650 nanometers is directed at the retina, irradiating it with safe power and effective time. This stimulates the retina to produce and release more dopamine, thickening the choroid at the posterior pole of the eye, restoring the elasticity of scleral fibers, and inhibiting axial elongation, thereby controlling myopia progression. More importantly, it can reduce the risk of fundus lesions, macular degeneration, and other potential side effects, such as cataracts caused by long-term irradiation of the lens.

[0048] Specifically, in this embodiment, the bottom support assembly 1 includes a base 101, a hollow support column 102, and a support rod 103. The base 101 is horizontally arranged, the hollow support column 102 is vertically and fixedly installed on the upper part of the base 101, and the support rod 103 is installed inside the upper end of the hollow support column 102 by adjusting bolts 104.

[0049] The bottom support component 1 using the above technical solution mainly consists of a base 101, a hollow support column 102, and a support rod 103. In use, the position of the support rod 103 inside the upper end of the hollow support column 102 can be adjusted by adjusting the bolt 104, thereby achieving the purpose of adjusting the height of the red light generating component 2. This allows the height of the adjustable light therapy device to be adjusted, making it suitable for myopic patients of different heights and practical.

[0050] Specifically, in this embodiment, the red light generating component 2 includes a housing 201, a filter 207, a rear cover plate 205, two sets of guide rails 208, a hollow sliding plate 209, a hollow mounting base 210, an electric push rod 211, and a red laser emitter 206. Two through holes 202 are formed on the front wall of the housing 201. The filter 207 is fixedly installed on the inner side of the front wall of the housing 201. The rear cover plate 205 is fixedly installed on the rear of the housing 201. Both sets of guide rails 208 are fixedly installed on the inner side wall of the housing 201 and are symmetrically arranged. Both sets of guide rails 208 are perpendicular to the filter 207. The hollow sliding plate 209 is slidably installed on the two sets of guide rails. Between 208, and the hollow sliding plate 209 is set parallel to the filter 207, the hollow mounting base 210 is fixedly installed on one end of the two sets of guide rails 208 facing the rear cover plate 205, the electric push rod 211 is fixedly installed on one side of the hollow mounting base 210 facing the hollow sliding plate 209, and the telescopic end of the electric push rod 211 is fixedly connected to one side of the hollow sliding plate 209 facing the hollow mounting base 210. There are two red laser emitters 206, and the two red laser emitters 206 are respectively set corresponding to the two through holes 202, and both red laser emitters 206 are installed on the side of the hollow sliding plate 209 facing the filter 207 through the lamp holder 203.

[0051] It is worth noting that the red laser emitter 206 can be a 650nm red laser emitter.

[0052] The red light generating component 2 using the above technical solution mainly consists of a housing 201, a filter 207, a rear cover plate 205, two sets of guide rails 208, a hollow sliding plate 209, a hollow mounting base 210, an electric push rod 211, and a red laser emitter 206. In use, the filter 207 filters out visible light emitted by the red laser emitter 206 with wavelengths outside the 630-650 nm range, allowing red light with wavelengths between 630-650 nm to be integrated and pass through two through holes 202 into the lens barrel assembly 3 for near-field emission. The device provides red light for treatment to patients. An electric push rod 211 drives a hollow sliding plate 209 to move linearly along two sets of guide rails 208, adjusting the distance between the red laser emitter 206 and the filter 207. This adjusts the intensity of the red light entering the lens barrel assembly 3, catering to patients with varying degrees of myopia. The adjustable intensity of the red light generated by this device allows for customized treatment, providing a better therapeutic effect.

[0053] Specifically, in this embodiment, the red light generating component 2 further includes two concave lenses 204. Both concave lenses 204 are fixedly installed on the side of the filter 207 facing the hollow sliding plate 209. The two concave lenses 204 are respectively set to correspond to two red laser emitters 206, and the two concave lenses 204 are also respectively set to correspond to two through holes 202.

[0054] The two concave lenses 204 configured using the above technical solution are used to disperse the red light entering the lens tube assembly 3, further reducing the intensity of the red light, so that the light-adjustable treatment intensity light-adjusting device can be used to treat myopic patients with a low degree of myopia.

[0055] Specifically, in this embodiment, the lens barrel assembly 3 includes a connecting plate 301 and two barrels 302. The connecting plate 301 is fixedly installed on the outer side of the front wall of the outer shell 201, and the two barrels 302 are fixedly installed on the side of the connecting plate 301 facing away from the outer shell 201. The two barrels 302 are respectively provided with two through holes 202, and the two barrels 302 are respectively connected to the two through holes 202.

[0056] The lens tube assembly 3, which adopts the above technical solution, mainly consists of a connecting plate 301 and two tubes 302. The two tubes 302 serve as the propagation channels for the red light emitted by the two red laser emitters 206. When in use, the nearsighted patient simply aligns their eyes with the end of the two tubes 302 that is away from the connecting plate 301.

[0057] Specifically, in this embodiment, the lens barrel assembly 3 also includes two silicone protective rings 303, which are respectively fitted onto the ends of the two barrels 302 away from the connecting plate 301.

[0058] The two silicone protective rings 303 provided by the above technical solution can prevent the eyes of nearsighted patients from directly hitting the end of the two tubes 302 away from the connecting plate 301 during use, thereby improving the safety performance of the lens tube assembly 3.

[0059] Specifically, in this embodiment, the lens barrel assembly 3 also includes two convex lenses 304, which are respectively installed inside the two barrel bodies 302.

[0060] The two convex lenses 304 configured in the above technical solution are used to focus the red light entering the two cylinders 302 to ensure that the red light entering the two cylinders 302 can be concentrated and illuminate the patient's pupils, thereby ensuring the treatment effect of myopia.

[0061] Specifically, in this embodiment, the control unit 4 includes a touch display 401 and a distance sensor 403. The touch display 401 is fixedly installed on the upper part of the housing 201, and a microcontroller electrically connected to it is built into the touch display 401. The microcontroller is electrically connected to the electric push rod 211 and two red laser emitters 206 respectively. A power switch 402 is also installed on the outer wall of the touch display 401. The distance sensor 403 is fixedly installed on the side of the hollow sliding plate 209 facing the filter 207, and the signal output terminal of the distance sensor 403 is electrically connected to the signal input terminal of the microcontroller through a signal line.

[0062] The control unit 4, which adopts the above technical solution, mainly consists of a touch screen display 401, a microcontroller inside the touch screen display 401, a power switch 402 outside the touch screen display 401, and a distance sensor 403. The touch screen display 401 is used to control the phototherapy device with adjustable treatment intensity, and to display the working status of the phototherapy device and set the working parameters of the phototherapy device with adjustable treatment intensity. The power switch 402 is used to turn the device on and off. The microcontroller is used to receive data uploaded by the distance sensor 403. When the distance data detected by the distance sensor 403 is no longer within the set range, the electric push rod 211 cannot continue to extend to prevent the red laser emitter 206 from colliding with the concave lens 204.

[0063] It is worth noting that the microcontroller can be an STC89C51; the distance sensor 403 can be one of an optical distance sensor, an infrared distance sensor, or an ultrasonic distance sensor.

[0064] Working principle: When using this adjustable intensity phototherapy device, the power switch 402 is turned on, and the working parameters of the device are set via the touch display 401. The device is then operated to enter the working state. During operation, the electric push rod 211 can be controlled via the touch display 401 to adjust the distance between the red laser emitter 206 and the concave lens 204, thereby adjusting the intensity of the red light. After adjustment, the nearsighted patient can align their eyes with the two silicone protective rings 303 attached to the ends of the two cylinders 302 away from the connecting plate 301 for treatment. The working time of the red laser emitter 206 can also be set via the touch display 401. When the working time of the red laser emitter 206 is completed, the microcontroller controls the two red laser emitters 206 to automatically stop working.

[0065] When the distance between the red laser emitter 206 and the concave lens 204 is too close, the distance sensor 403 uploads the detected distance data to the microcontroller. The microcontroller then controls the extension end of the electric push rod 211 to stop extending, thus preventing the red laser emitter 206 from colliding with the concave lens 204.

[0066] All parts not described in this invention are the same as or can be implemented using existing technology. Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
