Abstract

The invention relates to the technical field of medical demonstration teaching, specifically a cricothyroid muscle action demonstration model, which includes a model body and is arranged in a box. The model body includes a trachea, cricoid cartilage body, thyroid cartilage, arytenoid cartilage, thyroid cartilage, and hyoid bone body , vocal cords and cricothyroid muscle, the cricothyroid muscle function demonstration model, the model body is set in the box, has a good protective effect, the model body is lifelike, with the cricothyroid muscle, power supply and audio, it is convenient to simulate the action principle of the cricothyroid muscle, in The base is equipped with a frequency converter, which further facilitates the control of the contraction force of the cricothyroid muscle, thereby more realistically simulating the relationship between the contraction of the cricothyroid muscle and the change of the vocal cords. There is a lighting lamp on the protective case, which is convenient for students to learn and use.

Description

technical field [0001] The invention relates to the technical field of medical demonstration teaching, in particular to a cricothyroid muscle action demonstration model. Background technique [0002] It is well known that mammalian larynx is well constructed. The larynx is the enlarged part of the front end of the trachea. The larynx is composed of cartilage, ligaments, muscles and mucous membranes. The laryngeal muscle is the power organ of pronunciation, including cricothyroid muscle, cricoarytenoid muscle and thyroarytenoid muscle, etc. The contraction of cricothyroid muscle will increase the distance between the anterior horn of the cricoid cartilage and the arytenoid cartilage, tensing and lengthening the vocal cords. [0003] Among the existing models, there is no model demonstrating the principle of action of the cricothyroid muscle. SUMMARY OF THE INVENTION [0004] (1) Technical problems solved [0005] In view of the deficiencies of the prior art, the present ...
