Grating red light amblyopia treatment instrument

Abstract

The invention provides a grating red light amblyopia treatment instrument, which comprises a housing, wherein the housing is internally provided with a grating mechanism and a picture mechanism, and the housing is provided with a screen thereon; the grating mechanism comprises a grating belt, a driving roller, a rotation driving mechanism, a driven roller, a grating detection structure and a control circuit; the picture mechanism comprises a first light-transmitting plate, a second light-transmitting plate, an opening-closing structure, a clamping structure, a lifting structure, a roller, an inserting motor and a plurality of pictures; the opening-closing structure is arranged at the entrance so as to open or close a gap between the second light-transmitting plate and the side wall of theentrance; the clamping structure is arranged on the second light-transmitting plate and located outside the housing so as to clamp the pictures on the second light-transmitting plate; and the liftingstructure is fixed in the housing and arranged close to the entrance. The grating red light amblyopia treatment instrument has the beneficial effects that the occurrence of a phenomenon that a part ofrequired grating pieces and a part of adjacent grating pieces are on a working station is avoided, automatic involvement of the pictures is realized at the same time, and the housing is ensured to bein a closed state for a long time.

Description

technical field [0001] The invention relates to an amblyopia treatment instrument, in particular to a grating red light amblyopia treatment instrument. Background technique [0002] In the prior art, the grating red light amblyopia therapeutic apparatus includes a casing, on which a lens barrel assembly is arranged, and a red light source is arranged inside the casing, and the red light source and the lens barrel assembly realize red light emission from the lens barrel, and the macular area Mainly the cone cells, and the cone cells are most sensitive to red, so the pulsed red light only stimulates the cone cells to excite them, and the fovea has an absolute advantage, so as to achieve the purpose of central fixation and improve vision in the amblyopic eye; There is a grating mechanism in the casing, and a grating light source is set in the casing. The picture can be placed in the casing, and the picture is located between the grating light sources after being put in. The lig...

Problems solved by technology

[0003] 1) Since the grating sheet is replaced to the working station only by controlling the rotation time of the motor, each grating sheet is closely connected to the adjacent grating sheet, and there is a tightness of the convolution of each section of the grating sheet on the convolution cylinder Due to inconsistency and other reasons, after the motor rotates, not only one grating sheet is on the working station, but some grating sheets and some adjacent grating sheets are on the working station, and a picture that does not need to be displayed appears;

[0004] 2) The Chinese patent discloses a comprehensive amblyopia therapeutic apparatus with a three-level visual function whose notification number is CN 101156815 B. Although this therapeutic apparatus realizes how to place pictures in the casing to realize arbitrary replacement of displayed images, The treatment device needs to open the casing, which is easy to enter dust and other impurities. The casing is equipped with optical components, and the entry of impurities will greatly reduce the imaging effect and affect the treatment effect.
