Description

Photothermal effect type myopia physiotherapy instrument

Technical Field

The utility model relates to the field of disease treatment, in particular to a photothermal effect type myopia physiotherapy instrument.

Background

According to the research report of the world health organization, the number of myopia patients in China exceeds 6 hundred million, and the myopia rate of teenagers is high. Myopia prevention and control for children and teenagers are the work contents which are highly valued by the nation in recent years.

From the perspective of preschool education and school age education management, the method advocates increasing outdoor activity time of children and teenagers, improving classroom lighting conditions, paying attention to eye use hygiene habits, balancing diet and ensuring rest time, and students in middle and primary schools take out the students for eye exercises in fixed time intervals every day, so that the generation and development speed of myopia of the students is relieved through the methods. Although there are some effects, the effects are not ideal.

The product Lin Lang Manmu for preventing and controlling myopia of students on the market comprises daily articles such as ergonomic tables and chairs, eye-protecting lamps, sitting posture instruments, reading and writing boards, writing correctors and bad sitting posture reminding instruments, and also comprises eye drops with eye health care and myopia prevention and control functions, external plasters, health care products, reading and writing glasses, electrotherapy instruments, electric pulse instruments, moxibustion therapy instruments, binocular imaging instruments, crystal manipulation tools, thermotherapy instruments, ultrasonic therapy instruments, ion introduction instruments, acupuncture point massagers, linear training instruments, acupuncture point massages, acupuncture point beans and other hundreds of related products. In recent years, the ophthalmology field also advocates that children and teenagers use tools such as an adjusting function trainer, low-concentration atropine, corneal plastic glasses, myopic out-of-focus frame glasses and the like to help students to prevent and control myopia. The products and the methods for preventing and controlling myopia with various names and categories do not have the products and the methods which can completely block the development of myopia, and the essential problems are two: firstly, the deep mechanism of myopia development is not clear, and hidden factors are buried for all flowers struggle for the intervention means; second, the education of taking a trial forces teenagers and children to pay a lot of careless current situation of short-distance eye use duration, and although the national call gives students in middle and primary schools a burden and brings out a lot of detailed implementation rules, the effect is little.

In addition to orthokeratology and low concentrations of atropine, the efficacy predictability of other traditional myopia prevention and control methods and products is not ideal; most myopia prevention and control products can obtain certain efficacy only by taking out a great amount of time for using the products by a user, and if the using time is short, the satisfactory efficacy cannot be obtained, so that the myopia prevention and control products occupy the learning time of children in the school age; the atropine with low concentration still has certain side effects, such as photophobia and near vision difficulty; the orthokeratology mirror is expensive, is relatively complicated to take off and care, and is easy to cause keratoconjunctival infection and even perforation if being improperly used.

In recent years, scholars at home and abroad find that the occurrence and development of myopia are clearly associated with insufficient choroidal blood supply at the equatorial region and the posterior polar region of the fundus. In clinical practice for rehabilitation of other diseases of human body, among physiotherapy methods for improving blood supply, infrared technology is most widely used, and efficacy and safety thereof are widely accepted by academia and patients. The heat effect of the infrared rays can promote the bidirectional regulation of vascular nerves, reduce lipid peroxide and improve the nerve conduction efficiency; the infrared ray can also enhance the metabolic capability of tissues and promote the excretion of metabolic products of the organism; the infrared ray can activate mitochondria in cells, promote the metabolism change of histamine, kinins, 5-hydroxytryptamine, prostate, and the like, provide energy for the metabolism and the repair of body cells, and improve the internal and external environments of tissues.

The examples of using red visible light and infrared rays for physiotherapy in ophthalmology are few, and the reason is very concerned with the safety of light radiation. One of the theoretical bases of infrared physiotherapy is the thermal effect principle of light, and the thermal effect of light has certain danger when acting on eyeballs. In known spectrums, human eyes can cause crystal turbidity when being exposed to an infrared environment with the wavelength of 900-1000 nm for a long time; corneal injury can be caused by long-term exposure to a short-wave light environment of about 280 nm; retinitis can be caused by long-term exposure to short-wave light around 310 nm; prolonged exposure to short-wave light around 500nm can also lead to retinal and choroidal damage.

In the prior art, red visible light and infrared rays are mainly used for treating amblyopia in clinical ophthalmology, and a red light scintillation therapeutic apparatus, a helium-neon laser therapeutic apparatus and a semiconductor laser therapeutic apparatus with the wavelength of about 640nm are used for treating amblyopia in clinical ophthalmology. In recent years, doctors find that myopia develops very slowly during the period of treatment of amblyopia by using semiconductor laser therapeutic instruments with the wavelength of about 640nm for most patients with myopia and amblyopia.

The thermal effect of light is less useful in ophthalmology, and one reason for this is that far infrared rays cannot penetrate the cornea and enter the fundus.

Therefore, the spectrum which can penetrate through the refraction interstitium of the eyes and has proper penetration depth, the spectrum wavelength, the irradiation safety power and the irradiation safety duration range which have safety are found, and the light effect is the striving direction for the myopia prevention and control of children and teenagers.
