Problems solved by technology

The problems of this detection instrument are as follows: (1) One of the basis for detecting vertigo is only vertical amplitude or horizontal amplitude nystagmus, and there is no intuitive nystagmus map or accurate nystagmus data as the basis for diagnosis; (2) when the grating Improper position will cause deviation to the axis of movement of nystagmus; (3) When the low light emission is uneven or the angle is not appropriate, it may

Example Embodiment

[0021] The structure and working principle of the eye mask type vertigo detector of the present invention will be further described below in conjunction with the accompanying drawings.

[0022] refer to figure 1 , an eye mask type vertigo detector, comprising an eye mask 1 with an elastic fastening belt and a vertigo detection device installed on the eye mask. Among them, the vertigo detection device adopts a module design method, and according to the distance from the eyes from near to far (from the inside to the outside according to the eye mask), the infrared light source module board 5, the control board 4, the camera module board 3, the screen module board 2, The four parts are structurally connected through plug-in keys, and functionally connected through various transmission lines and circuits. The camera module and the infrared light source module form a nystagmus video image acquisition device, and the camera module and the infrared light source module are placed at ...

Abstract

The invention provides a blinder type dizziness detector which comprises a blinder with an elastic fastening strap and a dizziness detection device arranged on the blinder. The dizziness detection device comprises four parts which are an infrared source module plate, a control main board, a camera module plate and a screen module plate sequentially arranged from inside to outside. The four parts are connected integrally through pluggable keys and fixed on the blinder. In detection, the head of a patient is placed on the right position, infrared light generated by an infrared source illuminates the surfaces of eyeballs, a camera module obtains a nystagmus video image and sends obtained video image signals to the control main board to be processed, and key video frame pupil center marks and a nystagmus curve graph are drawn out and displayed on a screen to be provided for doctors or professional staff as reference for disease diagnosis. The blinder type dizziness detector is small in size, low in weight, compact in structure, high in integration level, and low in cost, achieves modularization of a collecting device, and has good portability.

Description

technical field [0001] The invention belongs to the technical field of medical devices, and relates to a vertigo detection device, in particular to an eye mask type vertigo detector, which is mainly used for detection and analysis of nystagmus and vertigo symptoms. Background technique [0002] Vertigo has long been recognized as a syndrome that is difficult to define, impossible to measure, challenging to diagnose, and problematic to treat. The subjective feeling during its attack can be summarized into four types. (1) vertigo: a spinning sensation of self and the external environment; (2) syncope: a feeling before or about to faint; (3) imbalance: a feeling of being unable to maintain balance; (4) dizziness or Nonspecific dizziness: A vague, indescribable feeling of lightheadedness or lightheadedness. These four types have influenced clinical practice until now, but they have been continuously questioned by clinical practice and research in recent years. A National Inst...
