Description
Technical field
This utility model relates to a kind of laryngophantom, a kind of movable laryngophantom.
Background technology
More existing laryngophantoms are fixed, cannot represent the moving situation of larynx in teaching, give teaching band
Be inconvenient for, student be difficult to understand for that vocal cords are nervous and lax, glottis splits greatly with reduce, and then can not well understand larynx
Motion principle.
Summary of the invention
In order to solve deficiency of the prior art, the purpose of this utility model is to provide a kind of arytenoid cartilage and first shape soft
Bone can be movable the movable laryngophantom of convenient teaching.
For achieving the above object, this utility model is by the following technical solutions:
A kind of movable laryngophantom, it includes that laryngophantom body, described laryngophantom body include tracheal cartilages, ring-type soft
Bone, thyroid cartilage, arytenoid cartilage；
Described tracheal cartilages is arranged over cricoid cartilage, and described cricoid cartilage is by arch of cricoid cartilage and lamina of cricoid cartilage structure
Becoming, the upper limb of described lamina of cricoid cartilage is provided with a pair arytenoid cartilage, and described cricoid cartilage both sides are provided with thyroid cartilage；
The attachment structure of described arytenoid cartilage and lamina of cricoid cartilage is: corresponding lamina of cricoid cartilage bottom described arytenoid cartilage
Junction is provided with circular shaft, and the junction of the upper limb correspondence arytenoid cartilage of described lamina of cricoid cartilage is provided with the cunning matched with circular shaft
Groove, described circular shaft is slidably located in chute；
The attachment structure of described thyroid cartilage and cricoid cartilage is: the junction of corresponding cricoid cartilage on described thyroid cartilage
It is provided with protrusion hemispherical, the recessed semi-spherical grooves in corresponding thyroid junction on described cricoid cartilage, described protrusion hemispherical
It is movably fastened in recessed semi-spherical grooves.
The cross section of described chute is semicircle.
The pair of arytenoid cartilage and corresponding chute are symmetrical arranged.
Described laryngophantom body is by PVC material molding.
This utility model uses above technical scheme, and described circular shaft is slidably located in chute so that arytenoid cartilage is permissible
The slip axially done back and forth along chute；The cross section of described chute is semicircle so that arytenoid cartilage can do along chute
Radial symmetric rotates；Well show the motion due to arytenoid cartilage can to student thus control glottis and split big or reduce.
Described protrusion hemispherical is movably fastened in recessed semi-spherical grooves, it is achieved that the action that thyroid cartilage can lean forward and reset,
Well show thyroid motion can to student thus control vocal cords anxiety or lax.This utility model is reasonable in design,
Practical.
