Description
Technical field
The utility model relates to Medical Devices or medical educational instrument, in particular to a kind of benign paroxysmal positional is dizzy
It swoons manual Teaching instrument.
Background technique
Benign paroxysmal positional vertigo (BPPV), is commonly called as otolith disease, is macula acustica utriculi and macula sacculi at inner ear vestibule
Otolith falls into dizziness caused by semicircular canal after falling off, occur when head position changes, and cause a series of symptoms, such as dizzy, nausea,
Vomiting etc., it is serious to influence normal life, fear is caused to patients ' psychological.Its disease incidence is about 65/10000, is most often
One of dizziness seen, therefore be also that we clinically need to be grasped knowledge.
Inner ear is a complicated structure, wherein being mutually perpendicular to two-by-two between three semicircular canals, posterior semicircular duct and horizontal half
The anatomical position regulated results in most BPPV and all occurs in this two semicircular canals, for the BPPV of different semicircular canals
Diagnosis, head need to be rotated certain angle to correspondingly left and right, rear and judge, and manual reduction treating BPPV
Process is even more cumbersome and complicated, such as Epley method, Barbecue method, Semont method, Gufoni method, each method require
Head is rotated towards different directions.In teaching process, although can be demonstrated at present by image or digital simulation 3-D image
This process, however due to there is no physical model operation, still allow people's indigestion, for beginner, be difficult to understand for
And grasp this partial content.
Summary of the invention
In response to the deficiencies in the existing technology, the utility model provides a kind of benign paroxysmal positional vertigo and shows manually
Instrument is taught, the instruments used for education are by complicated, abstract knowledge image, materialization, generation and hand in teaching process, BPPV
The process that method resets intuitively is shown, and keeps this partial knowledge no longer empty, it is difficult to understand, can allow beginner it is more preferable, faster,
The principle of this pathogenetic mechanism manipulative reduction is grasped more firmly, and the invention is easy to operate, is easy to grasp, and well
It compensates for and lacks the blank that physical model carries out BPPV teaching in clinic.
The utility model is to realize above-mentioned technical purpose by following technological means.
A kind of manual Teaching instrument of benign paroxysmal positional vertigo, including unilateral ear-drum model, the unilateral side ear-drum model
It is equipped with interconnected and orthogonal canalis semicircularis anterior, canalis semicircularis posterior and horizontal semicircular canal, further includes demonstration table, mobile jib and shifting
Lever；The upper surface of described demonstration table is connect with mobile jib one end ball pair, and the other end of the mobile jib and the unilateral ear-drum model connect
It connects；The mobile bar that can be moved but can not be rotated around mobile jib along mobile jib is cased on the mobile jib；Before the demonstration table, the left side
Angle mark is respectively equipped with the right side；The material of the unilateral side ear-drum model is transparent material, is put in the unilateral side ear-drum model
Set mobilizable otolith.
Further, the upper surface of described demonstration table is connect with previously by chamfered transition, and the inclined-plane is with angle above
120 °~150 °.
Further, the angle mark range is 30 °~150 °.
Further, the otolith shape is round or ellipse.
Further, the otolith surface is coated with color
The utility model has the beneficial effects that:
The manual Teaching instrument of benign paroxysmal positional vertigo described in the utility model, passes through unilateral ear-drum model, mobile jib
With the combination of mobile bar, beginner can be allowed more preferably, faster, more firmly to grasp the principle of this pathogenetic mechanism manipulative reduction,
And the invention is easy to operate, is easy to grasp, and is compensated in clinic well and lack physical model progress BPPV teaching
Blank.

Specific embodiment
With reference to the accompanying drawing and specific embodiment is further described the utility model, but the guarantor of the utility model
Shield range is not limited to this.
In conjunction with shown in Fig. 1, Fig. 2 and Fig. 3, the manual Teaching instrument of benign paroxysmal positional vertigo described in the utility model,
Including unilateral ear-drum model, the unilateral side ear-drum model is equipped with interconnected and orthogonal canalis semicircularis anterior, canalis semicircularis posterior
And horizontal semicircular canal, the model can be produced and generated by modeling with 3D printer.It is described unilateral side ear-drum model can also include
One ipsilateral outer ear model as direction guidance；The material of the unilateral side ear-drum model is transparent material, the unilateral side ear-drum
Mobilizable otolith is placed in model.The otolith shape is round or ellipse.The otolith surface is coated with obvious face
Color can be red or black.It further include demonstration table 1, mobile jib 3 and mobile bar 2；The upper surface of described demonstration table 1 and mobile jib 3 one
The connection of ball pair is held, the other end of the mobile jib 3 is connect with the unilateral ear-drum model；Being cased on the mobile jib 3 can move along mobile jib 3
