Description

Technical Field

[0001] This invention belongs to the field of medical testing equipment technology, specifically relating to an intelligent multidimensional head-shaking nystagmus test instrument, used for various examinations of nystagmus and eye movement diseases in otology, neurology, ophthalmology, and other related fields. Background Technology

[0002] Vertigo is a common clinical condition, mainly caused by diseases of the inner ear vestibule and related vestibular system. Vestibular function testing is the first step in the diagnosis, treatment and rehabilitation of vertigo and balance disorders. The head-shaking test (HST) is a commonly used method for testing vestibular function in clinical practice. The presence and characteristics of nystagmus induced after head shaking are used to assess the mid-frequency function of the horizontal semicircular canals of the inner ear.

[0003] The head-shaking nystagmus test has two forms: active and passive, neither of which affects the results. In the active form, the subject sits upright in a chair and actively shakes or nods their head along the plane of the semicircular canals. In the passive form, the examiner holds the subject's head with both hands to assist in head movement. The head-shaking nystagmus test has always been a bedside examination item for vestibular function, where the examiner visually observes the nystagmus evoked after head shaking. Currently, the HSN test can be performed in a vestibular function laboratory, where the subject wears a high-frame-rate video nystagmus camera blindfold to record the nystagmus evoked after active or passive head shaking.

[0004] However, the current head-shaking nystagmus test still has the following problems:

[0005] 1. The effective head-shaking stimulation position for the head-shaking nystagmus test is a 30° forward tilt of the head, keeping the horizontal semicircular canals in the horizontal plane. However, neither visual observation nor video nystagmography recordings can guarantee the effective head-shaking stimulation plane.

[0006] 2. Effective head-shaking stimulation relies entirely on the subjective feelings of the subject and examiner, lacking accurate indication of head-shaking speed or rhythm.

[0007] 3. The detection frequency for the horizontal semicircular canals is limited to 1-2 Hz, and other frequencies have not been covered, making missed diagnoses inevitable.

[0008] 4. The test targets only the horizontal semicircular canals. The inner ear has three semicircular canals (horizontal, anterior vertical, and posterior vertical). Currently, the head-shaking nystagmus test cannot examine the anterior and posterior vertical semicircular canals, which inevitably leads to missed diagnoses and delays in diagnosis and rehabilitation.

[0009] 5. Visual inspection is subject to subjective errors and misjudgment of nystagmus suppression. Video nystagmus recording needs to be completed in a special laboratory and lacks quantitative analysis, which cannot meet the needs of the majority of patients.

[0010] To address this, we propose an intelligent multidimensional head-shaking nystagmus testing instrument.

[0011] To address the problems raised in the background art, those skilled in the art have proposed an intelligent multidimensional head-shaking nystagmus testing instrument.

[0012] The information disclosed above in this background section is only for enhancing the understanding of the background section of this invention, and therefore may include prior art that is not known to those skilled in the art. Summary of the Invention

[0013] The purpose of this invention is to provide an intelligent multidimensional head-shaking nystagmus testing instrument to solve the problems mentioned in the background art.

[0014] To achieve the above objectives, the present invention provides the following technical solution:

[0015] A smart multidimensional head-shaking nystagmus testing device includes:

[0016] An eye-wearing frame, characterized in that: a buffer band is installed on the eye-wearing frame, a high-frame-rate camera eye mask is fixedly installed on the front side of the eye-wearing frame, and the high-frame-rate camera eye mask is installed in conjunction with the buffer band and the eye-wearing frame; a detection and recording component is installed on the eye-wearing frame, and the detection and recording component is electrically connected to an external computer.

[0017] Preferably, the eye support includes an elastic metal ring, and both ends of the elastic metal ring are integrally formed with mounting grooves.

[0018] Preferably, the buffer band includes an orbital protection rubber sheet, the front side of which is fixedly installed with an elastic metal ring, and elastic bands are fixedly installed on the rear sides of both ends of the orbital protection rubber sheet, with Velcro fasteners sewn to the ends of the two elastic bands.

[0019] Preferably, the high frame rate camera goggles include an eye shield, the rear side of which is fixedly installed with an eye socket protective rubber sheet, the upper side of which is fixedly installed with an elastic metal ring, and the front side of which is equipped with a snap-on cover at both eyes. The function of opening and closing the cover, or closing it individually or separately to provide a dark field of view, can adapt to different detection needs.

[0020] Preferably, the fastening cover includes a shielding cover, a plurality of insert rods are fixedly installed on the outer edge of the rear side wall of the shielding cover, a magnet is fixedly installed on the rear side of the insert rod, a plug sleeve is sleeved on the outer side wall of the insert rod, the plug sleeve is fixedly installed on the inner side wall of the eye shielding shell, and an iron block attracted to the magnet is fixedly installed inside the plug sleeve.

[0021] Preferably, the detection and recording component includes a mounting bracket, a metronome, a light source, a gyroscope, a smart data processor, a memory, and an output port. The mounting bracket is fixedly installed on the lower side of the elastic metal ring. A high-frequency adjustable high-frame-rate camera is mounted on the mounting bracket on the rear side of the cover. The metronome is fixedly installed in the mounting slot. The gyroscope is fixedly installed in the middle of the eye cover. The light source is fixedly installed on the high-frequency adjustable high-frame-rate camera. The metronome, light source, gyroscope, smart data processor, memory, and output port are all electrically connected to a computer.

[0022] Preferably, the high-frequency adjustable high-frame-rate camera includes a high-frame-rate camera body, with a rubber sticker fixedly installed on the opposite side of the high-frame-rate camera body and the mounting bracket. A mounting pin is inserted into the high-frame-rate camera body, and the mounting pin is fixedly installed with the mounting bracket. A spring is compressed at the outer end of the mounting pin, and the spring is compressed against the high-frame-rate camera body.

[0023] Compared with the prior art, the beneficial effects of the present invention are:

[0024] (1) The present invention uses an eye-wearing frame, a buffer band, an eye mask, and a detection and recording component in combination. The eye-wearing frame, buffer band, and eye mask are used to wear the detection and recording component on the patient's eyes. At this time, the camera body is rotated so that the shooting angle of the camera body and the illumination angle of the light are aligned with the eyeball. At this time, the metronome is activated by computer control, and different frequencies of sound signals and instructions are issued for the examination. The subject shakes his head or makes other head movements according to the rhythm. At this time, the camera body performs high-frequency multi-target shooting of the eyes. The video and digital information of eye movement and nystagmus are stored or transmitted to the computer. Medical staff can slow down the video for observation and evaluate the patient's condition. At the same time, the gyroscope records the head movement and monitors and corrects the head shaking and other head movement planes, so as to accurately record the nystagmus or eye movement state of the patient when shaking his head or making other head movements. Compared to the head-shaking nystagmus test, the vHST ensures standardized and effective head-shaking stimulation while monitoring and recording head-shaking-induced eye movements / nystagmus (HSEM / HSN). This avoids non-standard subjective perception by both the subject and the examiner, and can accurately control the head-shaking speed or rhythm indication. It is not limited to a detection frequency of 1-2Hz. At the same time, a high-frame-rate camera can record multi-target images of eye position and eye movements, reducing the problems of missed diagnoses and delays in diagnosis and rehabilitation.

[0025] (2) The present invention uses the elastic metal ring in combination with the buffer band and the eye mask. The elasticity of the elastic metal ring is used to clamp the eye socket protection rubber sheet and the elastic band so that they can be stably in contact with the patient's skin, which increases the friction and prevents the device from changing position when shaking the head. At the same time, the eye mask is equipped with a fastening cover. When performing single eyeball detection, the cover on one side can be installed on the eye cover shell by means of a plug rod, magnet, plug sleeve and iron block. The function of opening and closing the cover, and closing it individually or separately to form a dark field of view, can adapt to different detection needs.

[0026] The above overview is for illustrative purposes only and is not intended to be limiting in any way. In addition to the illustrative aspects, embodiments, and features described above, further aspects, embodiments, and features of the invention will become readily apparent from the accompanying drawings and the following detailed description.

[0040] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0041] Example 1:

[0042] Please see Figures 1-3 As shown, an intelligent multidimensional head-shaking nystagmus testing device includes:

[0043] A buffer band 2 is installed on the eye-wearing frame 1. A high-frame-rate camera eye mask 3 is fixedly installed on the front side of the eye-wearing frame 1. The high-frame-rate camera eye mask 3 is installed in conjunction with the buffer band 2 and the eye-wearing frame 1. A detection and recording component 4 is installed on the eye-wearing frame 1. The detection and recording component 4 is electrically connected to an external computer.

[0044] Specifically, the detection and recording component 4 of this device includes a mounting bracket 41, a metronome 42, a light 43, a gyroscope 44, an intelligent data processor 46, a memory 47, and an output port 48. The mounting bracket 41 is fixedly installed on the lower side of the elastic metal ring 11. A high-frequency adjustable high-frame-rate camera 45 is mounted on the mounting bracket 41 on the rear side of the cover 321. The metronome 42 is fixedly installed in the mounting slot 12. The gyroscope 44 is fixedly installed in the middle of the eye cover 31. The light 43 is fixedly installed in the high-frequency adjustable high-frame-rate camera 45. The metronome 42, the light 43, the gyroscope 44, the intelligent data processor 46, the memory 47, and the output port 48 are all electrically connected to a computer.

[0045] As can be seen from the above, the computer can control the lighting and closing of the light lamp 43, which can stimulate the eyes under different conditions. At the same time, it can record the nystagmus of the patient under different conditions, which can effectively evaluate the patient's nystagmus.

[0046] Specifically, the high-frequency adjustable high-frame-rate camera 45 includes a high-frame-rate camera body 451. A rubber sticker 452 is fixedly installed on the opposite side of the high-frame-rate camera body 451 and the mounting bracket 41. A mounting pin 453 is inserted into the high-frame-rate camera body 451 and fixedly installed with the mounting bracket 41. A spring 454 is pressed against the outer end of the mounting pin 453. The spring 454 is pressed against the high-frame-rate camera body 451. The high-frame-rate camera body 451 used is a high-frequency multi-point high-frame-rate camera.

[0047] Working Principle: This invention utilizes the combined use of an eye-mounted frame 1, a buffer strap 2, an eye mask 3, and a detection and recording component 4. The eye-mounted frame 1, buffer strap 2, and eye mask 3 are used to attach the detection and recording component 4 to the patient's eyes. The camera body 451 is rotated so that its shooting angle and the illumination angle of the light source 43 align with the eyeball. At this time, a computer-controlled metronome 42 is activated, issuing different frequency sound beats and instructions required for the examination. The subject shakes their head or performs other head movements according to the beat. The camera body 451 then performs high-frequency, multi-target shooting of the patient's eyes. The captured video can be stored, output, or transferred to a computer. Medical personnel can slow down the video for observation and assessment of the patient's condition. Simultaneously, a gyroscope 44 records head movements and monitors and corrects head shaking and other head movement planes, accurately capturing and recording the patient's nystagmus or eye movement state during head shaking and other head movements. Compared to head-shaking nystagmus testing, vHST ensures standardized and effective head-shaking stimulation while monitoring and recording head-shaking-induced eye movements / nystagmus (HSEM / HSN). This avoids non-standard subjective perception by both the subject and the examiner, allowing for accurate control of head-shaking speed or rhythm indications. Furthermore, it is not limited to a detection frequency of 1-2 Hz. Simultaneously, a high-frame-rate camera can record multiple target points, reducing the risk of missed diagnoses and delays in treatment and rehabilitation.

[0048] This vHST can be used as a standalone portable head-shaking test instrument, allowing for real-time observation, data acquisition, and intelligent analysis of nystagmus / eye movement induced by the opening and closing of the eye mask (later connected to a computer or information center via mobile storage for display and output of test reports), or connected to an output display (such as a mobile phone) for real-time observation and analysis of eye movement and nystagmus information from the head-shaking test (later also connected to a computer or information center via mobile storage for display and output of test reports), serving patients at the grassroots level; it can also be combined with a computer and printer to form an independent multi-frequency, multi-dimensional head-shaking test detection system.

[0049] Example 2:

[0050] Please see Figure 1 and Figure 3 As shown, the eye-wearing frame 1 includes an elastic metal ring 11, and both ends of the elastic metal ring 11 are integrally formed with mounting grooves 12.

[0051] Specifically, the buffer band 2 includes an eye socket protection rubber sheet 21. The front side of the eye socket protection rubber sheet 21 is fixedly installed with an elastic metal ring 11. Elastic bands 22 are fixedly installed on the rear sides of both ends of the eye socket protection rubber sheet 21. The ends of the two elastic bands 22 are sewn with Velcro 23 that are mutually adhesive.

[0052] Specifically, the high frame rate camera eye mask 3 includes an eye cover 31, the rear side of which is fixedly installed with the eye socket protection rubber sheet 21, the upper side of which is fixedly installed with the elastic metal ring 11, and the front side of which is fitted with a fastening cover 32 at both eyes.

[0053] Specifically, the snap-fit ​​cover 32 includes a shielding cover 321. Multiple insert rods 322 are fixedly installed on the outer edge of the rear side wall of the shielding cover 321. A magnet 323 is fixedly installed on the rear side of the insert rods 322. An insertion sleeve 324 is sleeved on the outer side wall of the insert rods 322. The insertion sleeve 324 is fixedly installed on the inner side wall of the eye shielding shell 31. An iron block 325 that attracts the magnet 323 is fixedly installed inside the insertion sleeve 324.

[0054] As can be seen from the above, the present invention utilizes the elastic metal ring 11 in conjunction with the buffer band 2 and the high-frame-rate camera goggles 3. By using the elasticity of the elastic metal ring 11, the orbital protective rubber sheet 21 and the elastic band 22 can be stably held in contact with the patient's skin, increasing friction and preventing the device from changing position when the head is shaken. At the same time, the high-frame-rate camera goggles 3 are equipped with a fastening cover 32. When performing single eyeball detection, the cover 321 on one side can be installed on the eye cover shell 31 through the insertion rod 322, magnet 323, insertion sleeve 324 and iron block 325, realizing the function of being able to be closed into dark field of view individually or separately, adapting to different detection needs.

[0055] All standard parts used in this invention can be purchased commercially, and irregularly shaped parts can be customized according to the description and drawings. The specific connection methods for each part all employ conventional methods such as bolts, rivets, and welding, which are mature technologies in the prior art. The machinery, parts, and equipment all use conventional models in the prior art, and the circuit connections also use conventional connection methods in the prior art, which will not be detailed here.
