Folding ruler for viewing space function

Technical Field

The utility model belongs to the field of medical equipment, concretely relates to folding chi for looking space function.

Background

Unilateral visual space neglect (USN), abbreviated as paralateral neglect, is a visual space attention disorder of patients with brain injuries (including stroke, craniocerebral trauma, brain tumor, etc.). With the increasing incidence of brain injury, the unilateral neglect becomes a serious clinical problem, and an effective rehabilitation measure is urgently needed. In short, the patient's vision receives all the information in the visual field, but the brain does not recognize the information, thus causing a pathological phenomenon in which part of the visual space is neglected by cognition.

Patients with paralateral neglect are often accompanied by impaired visual field. Statistically, about 50% of clinically neglected patients may be accompanied by unilateral homeotic hemianopsia. Normally, the visual field in the normal horizontal plane of both eyes is in the region of about 60 degrees or less on the left and right, and the visual field in the vertical plane is in the region between 50 degrees above the horizon and 70 degrees below the horizon. Partial or complete loss of vision in the half-lateral field of vision in one or both eyes is called hemianopsia. In short, the absence of half of the patient's visual field in one or both eyes. In addition, other abnormalities in the visual spatial perception, such as shifts in the subjective visual perpendiculars, can occur in patients with various brain diseases or brain trauma. In short, it is the object that the patient sees that does not correspond to its actual position. These may be accompanied by the occurrence of paralateral neglect.

The occurrence of lateral neglect, hemianopsia and visual space perception disorder can block the process of the whole function recovery of the patient, prolong the period of rehabilitation training and seriously affect the daily life activities of the patient. However, various visuospatial dysfunctions have different pathogenesis, so that the visual spatial function of the patient is correctly evaluated, the etiology is known, and a targeted effective training measure is taken, which has important significance for promoting the overall rehabilitation of the patient.

Ophthalmology is usually used for examining the visual field range of a patient by using a perimeter, but a brain injury patient usually shows various dysfunctions, the examination cannot be completed well in a matching mode, and the detection accuracy is influenced. And the perimeter cannot check other view space functions and also cannot be used as a training device. At present, no multifunctional visual field and visual space examination and training equipment suitable for patients with visual space disorder exists clinically.
