Abstract

The utility model relates to a mechanic artificial larynx, which is suitable for recovering the patient's sound with excised larynx, comprising a sound cylinder, an air faucet, a membrane sheet, and a guide tube. The air faucet is arranged in the inner cavity of the sound cylinder, and the air faucet is provided with an air inlet opening and an air outlet. The outer side of the air outlet is provided with the membrane sheet, the air inlet opening and the guide tube are communicated. When in use, the sound cylinder is abutted on the throat point; the guide tube is put in the mouth cavity, so as to pronounce. The utility model has the advantages of clear sound, sonorousness, noiseless, small external dimension, and low cost, and is suitable for the patient with laryngeal cancer who recovers the sound after excising the whole larynx.

Description

Mechanic artificial larynx
This utility model relates to a kind of bionical synthetic hair mixer, and particularly a kind of larynx that recovers is extractd the mechanical artificial larynx that the patient pronounces.
Normal person's sounding is that air in the lung chamber is through bronchus, trachea flows through vocal cords, cause sounding behind the vocal cord vibration, and then through last larynx, pharyngeal cavity, nasal cavity or oral cavity excrete, after some patient extracts owing to the disease larynx, trachea directly is sewn to neck central authorities, just mute, for the patient can recover function of pronunciation, Chinese patent CN8620433 discloses a kind of " artificial electronic larynx ", it is the pulse signal that produces in the electronic amplifying circuit, send the transducing tone generator to convert audio signal to, make the transducing tone generator send the sound of certain frequency, but this " artificial electronic larynx " exist the cost height, noise is big, the distortion rate height, the shortcoming that service life is short.
The purpose of this utility model provides a kind of simple in structure, noiseless, and high-fidelity is carried and mechanical artificial larynx easy to use.
The purpose of this utility model is achieved in that this machinery artificial larynx comprises that sounding tube, gas are chewed, diaphragm and conduit, at the inner chamber of sounding tube a gas being installed chews, this gas has been chewed an air inlet and an air vent, and at diaphragm of arranged outside of air vent, air inlet is connected with conduit.During use, the sounding tube is against the trunnion place, conduit is put into the oral cavity, and the air-flow that is sent by pulmonary is through the modulation of tongue, tooth, lip organ, and after entering gas and chew by conduit, vibrating diaphragm can send various language again.
This utility model pronounces distinctly, loud and clear, noiseless, overall dimensions is little, cost is low, is fit to the full larynx of patients with laryngeal carcinoma and extracts the back and recover pronunciation and use.
Fig. 1 is the front view of mechanical artificial larynx.
As shown in Figure 1: this machinery artificial larynx comprises sounding tube 1, gas chews 4, diaphragm 3 and sebific duct 5, sounding tube 1 is by the hard plastic injection molding molding, it is horn-like that profile is, the waist in chamber is marked with a round-meshed catch 2 within it, prevent that condensed water from entering the inner chamber of sounding tube 1, connect a gas in the thread in inner cavity of sounding tube 1 and chew 4, chew at this gas and to be provided with an air inlet 6 and an air vent 7 on 4, air inlet 6 is pegged graft with sebific duct 5, fixed a diaphragm 3 that latex is made in the rear end of air vent 7, air-flow can be by the both sides of diaphragm 3, and the circular hole of catch 2 enters the back cavity of sounding tube 1.During use, the oral cavity is put in the termination of sebific duct 2, the sounding tube is against the trunnion place,, the gas that is sent by pulmonary is just through the modulation of tongue, tooth, lip organ, enters gas according to certain frequency of vibration and chews 4 and drive diaphragms 2 vibrations, diaphragm 2 plays normal person's vocal cords effect, can send various language.

Claims (2)

1, a kind of mechanical artificial larynx, it comprises that sounding tube, gas are chewed, diaphragm and conduit, it is characterized in that at the inner chamber of sounding tube a gas being installed chews, and this gas has been chewed an air inlet and an air vent, at diaphragm of arranged outside of air vent, air inlet is connected with conduit.
2, a kind of mechanical artificial larynx according to claim 1 is characterized in that the profile of sounding tube is horn-like, and the waist in chamber is marked with a round-meshed catch within it.
