Description
Technical Field
The utility model relates to the field of medical technical equipment, in particular to a head frame auxiliary device special for vestibule function examination.
Background
Vestibular function is one of the 3 major factors in maintaining the balance of the body. The organ responsible for vestibular function, called vestibular apparatus, is located in the inner ear and comprises 3 semicircular canals (outer, upper and rear semicircular canals), an oval sac and a balloon. There is a sacculus spot, or otolith, in each of the oval sac and the sacculus. These are all vestibular peripheral receptors. The elliptical sac and the balloon are statically balanced (e.g., sitting or standing). When the human body balance is disturbed, such as walking to one side, vestibular function examination is needed to determine whether the vestibule is diseased or not, and the pathological degree and nature of the vestibule. The degree and the position of the vestibular system lesion can be boosted by observing the spontaneous signs caused by the vestibular system lesion or by observing the vestibular reaction induced by certain physiological or non-physiological stimulation.
At present, the examination of the vestibular function comprises a double-temperature experiment, a head-swinging experiment, a vestibular evoked myogenic potential, a vestibular-ocular movement reflex and the like, but the evaluation of the function state of the vestibular is still incomplete, the examination of the vestibular-ocular movement reflex is more complex, the understanding of the vestibular visual conduction pathway is more fuzzy, and through the reading of related documents, a subjective visual vertical line (SVV) and a subjective visual horizontal line (SVH) can be used for the evaluation of the function of the otolith apparatus.
The subjective visual vertical line or subjective visual horizontal line test is to detect the degree of deviation of subjective visual perception of a person from the gravity vertical line or gravity horizontal line with dark light perpendicular to the ground or dark light horizontal to the ground in a dark environment without any visual reference. Research shows that the SVV deviation of normal people is within +/-2 degrees, and after the neural pathways of one otolith apparatus and the otolith apparatus are damaged, the information of the two otolith apparatuses entering the center is asymmetric, so that misjudgment on a gravity vertical line is generated on the level of cerebral cortex, and larger deviation is caused.
SVV/SVH can help to assess the damage of the vestibular otolith apparatus, can reflect the static compensation state of the otolith apparatus function, combines the examination with the existing vestibule assessment technology, can more comprehensively reflect the vestibule function and the vestibule compensation state, and guides the vestibule rehabilitation. However, there are currently no fixed standard instruments, software devices for accomplishing this examination.
At present, a test software installed on a computer is used during examination, but a patient is required to be completely in a dark environment, and a cylinder is required to be arranged between the head of the patient and a display screen, so that the sight of the patient is completely concentrated on a circular display screen, and the subjective judgment is avoided by external reference; however, at present, there is no special headgear aid, and medical personnel are replaced with a cylinder covering black cloth; which not only affects the measurement effect but also is very inconvenient to operate.
