Description

Technical Field

[0001] The present invention relates to the technical field of medical auxiliary devices, and particularly relates to an auxiliary device for the head-shaking test of vestibulo-ocular reflex examination. Background Art

[0002] The vestibulo-ocular reflex (VOR) is one of the important physiological reflexes of the human body. Its function is to cause eye movement by activating the inner ear vestibular system, so as to stabilize the image on the retina during head movement. Impairment of VOR can lead to problems such as difficulty in reading and walking for patients. Therefore, accurately detecting the VOR function is crucial for the diagnosis and treatment of vestibular system diseases. Currently, the VOR examination is mainly achieved through the head-shaking test, but the existing examination methods have certain limitations and risks.

[0003] In the current head-shaking test, Test Method 1: Manual operation and visual observation. It mainly tests the horizontal semicircular canal. The patient stares at the examiner's nose tip, and the examiner shakes the patient's head. The head-shaking direction is unpredictable, and it is operated at a small amplitude and high speed. Test Method 2: The patient wears an eye mask and sits on an examination chair at a certain distance from the visual target. The operator stands behind the patient, and the head-shaking direction is unpredictable, and it is also operated at a small amplitude and high speed.

[0004] Both of these two test methods require the operator to manually shake the head at a small amplitude and high speed. However, there is no targeted auxiliary protection device for patients in the current head-shaking test. On the one hand, some patients have unobvious or unreported cervical discomfort. On the other hand, some examiners have insufficient control over the amplitude and strength. When the high-speed head-shaking operation is improper, due to the lack of a supporting buffer protection structure, it may cause cervical spine injury to the patient due to improper operation. Summary of the Invention

The mandibular support 8 of the flexible neck protection structure is positioned to hoop the patient's mandible, and then the first elastic band 9 is adjusted to be tightened and fixed. With the patient's head and shoulders as the fulcrum, bilateral elastic support and protection are formed by the left support band 4 and the right support band 5 in the neck area. During the experiment, no matter whether the patient's head makes a shaking movement in the left-right direction or the up-down direction, the elastic components can absorb the impact force for buffering, which can reduce the stress on the patient's cervical vertebrae and improve safety. Among them, the left support band 4 and the right support band 5 can be made of silica gel bands, and the first elastic band 9 can be a tie or a hook-and-loop fastener band.

[0028] Preferably, both the left shoulder clip 1 and the right shoulder clip 2 have a U-shaped clip body, and a second elastic band 10 for tightening the opening of the U-shaped clip body is installed at the opening of the U-shaped clip body. Among them, in order to balance the material strength and lightweight weight reduction design, the left shoulder clip 1 and the right shoulder clip 2 can be made of lightweight aluminum alloy frames, and a soft pad is covered on the surface of the frames to contact the patient. The second elastic band 10 can be a tie or a hook-and-loop fastener band.

[0029]

This design facilitates the quick installation and replacement of the left elastic strip 11, and the left buffer effect can be adjusted by adjusting the number and material of the left elastic strip 11.

[0031]

Third Embodiment

[0032]

Fourth Embodiment

[0033] Preferably, both the extension rod 17 and the vertical rod 18 are telescopic rods that can be extended or shortened and then fixed in shape, which are used to adjust the distance and height of the visual target 19 relative to the patient according to the patient's body shape, eyesight and test requirements. Among them, the telescopic rod structure can adopt the common internal and external nested threaded pipe structure.

[0034] In this embodiment, the extension rod 17 is detachably installed on the cross bar 3, and the distance of the visual target 19 relative to the patient can be adjusted according to the patient's eye condition and test requirements during the head-shaking test. Even the extension rod 17, the vertical rod 18 and the visual target 19 can be separately removed and placed on a suitable carrier as a visual target assembly. Such as Figure 5As shown in the figure, the extension rod 17 is a multi-section telescopic rod. Two bottom support rods 25 are rotatably mounted on the outer wall of the outermost section of the extension rod. When it is necessary to disassemble the visual target assembly and place it at the test required position, the extension rod 17 can be retracted, and the two side bottom support rods 25 can be opened outwards to form multi-point bottom support feet, which stably support the vertical rod 18 and the visual target 19 at the top. As a reinforcement design, a threaded connection base 26 is provided on the cross bar 3, and a plurality of reinforcing blocks 27 are arranged at equal intervals on the outer wall of the threaded connection base 26 to enhance the structural strength of the connection of the cross bar 3.

Based on the mature development of foldable screen display technology, the display terminal can also be a foldable screen. The foldable screen is opened during the test to obtain a larger display area, which is suitable for displaying larger-sized image content. The display terminal can display the image information required during eye examinations through built-in application programs, or communicate with the upper computer through a wireless communication module, and receive the test content sent by the upper computer such as a handheld terminal or a desktop terminal.
