High Speed ​​Video Nystagmometer System

Abstract

The invention discloses a high-speed video nystagmus instrument system. The system comprises a nystagmus recording instrument, a PC terminal and a wireless transmission module used for establishing the communication connection between the nystagmus recording instrument and the PC terminal; the nystagmus recording instrument comprises an eyeshade, a video collecting assembly arranged in the eyeshade and a core control module arranged in the eyeshade; a video decoding module, a pupil tracking module and a diagnostic module are embedded in the PC terminal. According to the nystagmus instrument system, nystagmus video information is obtained through the nystagmus recording instrument, the nystagmus video information is transmitted to the PC terminal through the 5G frequency range wireless transmission module to perform operations of video decoding, analyzing and the like, nystagmus information recording and recognizing functions in BPPV diagnosis are completed, and a foundation is laid forthe diagnosis of diseases. By the using of a 5GHz WiFi module, high-speed transmission of videos is ensured, the anti-interference capability of the nystagmus recording instrument is improved, the obtaining of high-definition and high-frame-rate nystagmus videos is achieved, and the accuracy of the system is improved.

Description

technical field [0001] The invention relates to the field of nystagmometers, in particular to a high-speed video nystagmometer system. Background technique [0002] Benign positional paroxysmal vertigo (BPPV) is a transient vertigo induced by head movement to a specific position. It is a self-limiting peripheral vestibular disorder. BPPV can occur on either side Any of the semicircular canals can also occur in both sides and more than two semicircular canals at the same time. The commonly used diagnostic method for BPPV is the Hallpike displacement nystagmus test. The key to diagnosis is to determine the laterality and positioning according to the typical characteristic nystagmus induced by the displacement test.

Problems solved by technology

[0003] Common nystagmus observation and recording methods are mainly divided into three types: naked eye observation, electronystagmography, and video nystagmus. Among them, the naked eye observation method is to directly observe nystagmus, which has strong subjectivity, large errors, and weak nystagmus. Difficult to observe and other problems; electronystagmography uses electronic equipment to record the potential changes between the cornea and retina to record nystagmus, the back of the eyeball and retina are negatively charged, while the front of the eyeball and cornea are positively charged, so eye movement occurs If the potential changes, stick electrodes around the eyeballs, and the potential changes caused by eye movements will be recorded. Electronystagmography is an objective record of nystagmus, which is more accurate than naked eye observation. The cornea is affixed with biological electrodes, which will easily make the patient's eyeball feel uncomfortable, and will be affected by the physiological potential of the electrode placement position, resulting in detection errors; the video nystagmus method uses infrared technology to record nystagmus, because it does not need to contact the patient's eyeball, it will not It causes discomfort to the patient and eliminates the disadvantage that the electrode is susceptible to interference. It has been widely used in actual clinical practice in recent years.

[0004] Most of the existing video nystagmus recorders use wired transmission, and their spatial rotation is poor. Since displacement experiments are required to induce nystagmus, special techniques are also required to reset during treatment, and the use of cables is not conducive to diagnosis. and treatment; the existing wireless nystagmus recorder has a low acquisition resolution or frame rate, resulting in insufficient accuracy of the system and lack of recording of weak nystagmus
