Description

Retinopathy inspection device Technical Field The invention relates to the technical field of medical appliances, in particular to a retinopathy checking device. Background In screening diagnosis of diabetic retinopathy, the difficulty in matching of patients due to unstable fixation and photophobia is a key technical bottleneck affecting the image acquisition quality. In terms of fixation, it is difficult for existing examination devices to effectively inhibit micro-movements caused by physiological tremors or limitation of movement of the patient. Such involuntary head misalignment, which leads to image blurring in fundus photography, introduces motion artifacts in Optical Coherence Tomography (OCT), severely interfering with the judgment of retinal microstructure; Meanwhile, in the aspect of photophobia management, strong light stimulus at the moment of shooting can trigger instinctive eye closure reflex of a patient, and shooting failure is directly caused. In addition, the continuous discomfort of glare also makes it difficult to stably watch the target point, so that the eyeball drifts and the accurate capture of a key focus area is affected; Therefore, we propose a retinopathy inspection device, which can effectively realize fixation of patients and reduce the influence of light on the detection result. Disclosure of Invention Aiming at the defects in the prior art, the invention provides a retinopathy checking device which is used for improving the accuracy of checking results of diabetic retinopathy patients. In a first aspect, the invention provides a retinopathy examination device which comprises an examination main body, a fixed rack and a shading component, wherein the examination main body is used for examining retinopathy, the fixed rack is arranged at one end of the examination main body and used for supporting and fixing the head of a patient to be examined, and the shading component is rotatably arranged on the examination main body, is abutted with the fixed rack and is used for shading light. Further, the fixed rack comprises a sliding table, an underframe and a head placing main frame, wherein the underframe is arranged on the sliding table, and the head placing main frame is arranged on the underframe.
