Embodiment 1

[0046] A light source device for an instrument for alleviating diabetic retinopathy, comprising: a light emitting device 1, a light guide plate 2 located on the same plane as the light emitting device 1 and having a light field area and a non-light field area, a light guide point array 3 arranged in the light field area, and The light-absorbing layer 4 is arranged in the non-light field area; the front of the light guide plate 2 is also provided with a light diffusion plate 5 , and the back of the light guide plate 2 is also provided with a light-shielding absorption plate 7 .

[0047] In this embodiment, the light diffusion plate 5 is a translucent, white frosted PC sheet with a thickness of about 0.2 mm. The light-shielding absorbing plate 7 is made of matte matte black PET material, which produces good light-absorbing and light-shielding effects.

[0048] The specific setting method of the light guide point array 3 in this embodiment is:

[0049] With the light-emitting de...

Embodiment 2

[0053] The difference between this embodiment and Embodiment 1 is that in this embodiment, in order to improve the therapeutic effect, a light-shielding absorption band 8 is also provided on the side of the light guide plate 2, as figure 1 shown. The light-shielding absorption band can effectively reduce the reflection interference of the side wall of the light guide plate to the light, effectively improve the luminous uniformity of the light guide plate, improve the quality of the light guide plate, and further improve the therapeutic effect.

Embodiment 3

[0055] The difference between this embodiment and embodiment 2 is that this embodiment adds a reflection cup 6, and the specific settings are as follows:

[0056] In order to maximize the introduction of light into the light guide plate and improve the light guide efficiency, a reflective cup 6 is provided on one side of the light emitting device 1, the light emitting device 1 is fixed at the middle position of the reflective cup 6, and the light emitting device 1 Located between the reflective cup 6 and the light guide plate 2, such as figure 1 and figure 2 shown.

Abstract

The invention discloses a light source device of an instrument for relieving diabetes fundus lesions. The problem that the irradiation shape of an existing light source lighting area is not suitable for the instrument for relieving the diabetes fundus lesions is solved. The light source device comprises light emitting equipment, a light guide plate, light guide point arrays and a light absorption layer, wherein the light guide plate and the light emitting equipment are located on the same plane, the light guide plate is provided with a light field area and a non light field area, the light guide point arrays are arranged in the light field area, and the light absorption layer is arranged in the non light field area. According to the light source device of the instrument for relieving the diabetes fundus lesions, the shapes of lighting areas are effectively and automatically determined by arranging the light absorption layer to be in different shapes, the purpose of uniform light source is achieved through the effect of the light guide plate, and thus the light source device is extremely suitable for the instrument for relieving the diabetes fundus lesions; meanwhile, the light guide point arrays are optimally designed, so that not only can the light uniformity be effectively and greatly increased, but also the situation that dark spots and bright spots exist in the light field area can further be effectively avoided, and the effect of relieving the diabetes fundus lesions is further improved.

Description

technical field [0001] The invention relates to a medical device, in particular to a light source device of an instrument for alleviating diabetic retinopathy. Background technique [0002] Hazards of diabetic eye disease: Diabetic eye disease is the most common complication of diabetes, including diabetic macular edema, retinopathy, etc., and is the most common cause of preventable blindness in adults. According to the epidemiological survey data of the Diabetes Society of the Chinese Medical Association and the Society of Ophthalmology, in my country, the prevalence of diabetes among adults over the age of 20 is 9.7%, which is the country with the largest number of diabetic patients in the world. Among them, the prevalence rate is 24.7%~37.5%. [0003] Pathogenesis of diabetic eye disease: The current medical community lacks a comprehensive understanding of the pathogenesis of diabetic eye disease, but a large number of clinical trials have shown that a series of chain rea...
