Description

Red light treatment device for increasing fundus irradiation area

Technical Field

The utility model relates to an eye treatment equipment technical field, concretely relates to increase ruddiness treatment device of eye ground irradiation area.

Background

Photobiomodulation utilizes the photochemical transformation potential of low intensity red and near infrared light to cause photochemical reactions in target tissues, including increasing cytochrome C oxidase activity, altering gene expression to modulate the mitochondrial respiratory chain, increasing the biological activity of nitric oxide, and the like.

In recent years, the low-energy LED laser therapeutic apparatus on the market provides a method for increasing the blood flow and metabolic rate of the ocular fundus, and aims to improve the effect of ocular tissue injury repair, including but not limited to the remodeling of scleral fibroblasts and the repair of visual function cells, by increasing the blood flow and metabolic rate of ocular fundus tissues, so as to achieve the effect of preventing, slowing, preventing and even reversing eye diseases.

However, some products appearing on the market for treating myopia and amblyopia by using low-energy laser, such as the light path shown in fig. 3, are common light-feeding instrument light path designs on the market, and light incident to the pupil is myopia parallel light, and forms micron-level light spots on the retina after the light is focused by the pupil 2. There are two disadvantages to this: 1) on the micron-scale light spots, the energy is too concentrated, and the risk of damaging the retina is caused; 2) the irradiation area is not large enough, and more retinas can not receive light, thereby achieving better treatment effect.

For this reason, we propose a red light treatment device that increases the fundus irradiation area.

Detailed Description

In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, but not all, embodiments of the present invention. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative efforts belong to the protection scope of the present invention.

Referring to the attached drawings 1-2, a red light treatment device for increasing the irradiation area of the fundus oculi comprises an instrument shell 5, a laser LED light source 1 arranged on one side of the inner wall of the instrument shell 5, an optical scattering component 3 which is in the same straight line with the laser LED light source 1 is also arranged in the instrument shell 5, the optical scattering component 3 can be directly fixed on the instrument shell 5 and also can be connected with the instrument shell 5 in a detachable mode, or is arranged on a replaceable component (such as a detachable component or an eyeshade) and can be replaced by a replaceable component without the optical scattering component 3, so that the instrument can simultaneously perform treatment functions such as afterimage or multispectral and the like;

the instrument shell 5 is provided with a light outlet on the extension line of the laser LED light source 1 and the optical scattering component 3, the outer edge of the light outlet is provided with a limiting device 4, the limiting device 4 is a plastic shell or a silica gel sleeve,

the distance between the optical scattering component 3 and the pupil 2 is not more than 8cm, and in the range, the laser LED light source 1 can irradiate more and more fully into the through hole 2, so that the treatment effect is improved;

the laser LED light source 1 is a low-energy red laser light source, the spectral range is 630nm-666nm, and the energy range of the irradiated low-energy red laser is 0.2 mw-10 mw; the damage to the glasses can be reduced;

the optical diffusion member 3 changes the optical path to change the light incident on the pupil into diffused light entering from various angles in the vicinity of the front side of the pupil. The scattered light can have a larger irradiation area on the fundus, so that a larger area is stimulated by red light, and the treatment effect is improved;

the limiting device at the front end of the pupil 2 is used for limiting the distance between the pupil 2 and the optical scattering component 3, so that the energy density and the area irradiated to the fundus can be optimally selected.

As shown in fig. 1-2, a low-energy red laser beam is emitted from a laser LED light source 1 and irradiated onto a light scattering member 3. After the light passes through the light scattering member 3, each part of the light scattering member 3 scatters the light, so as to ensure that the light can enter the pupil 2 at each part of the light scattering member, and thus, a light spot with a large arc surface like ACB shown in fig. 2 is formed in the pupil 2. The larger light spot has lower energy density than the light spot formed by the traditional phototool, and can avoid damage to the retina. Meanwhile, larger retinas can be irradiated by low-energy laser, and the retinas in a larger range can be treated, so that the myopia is delayed and treated.
