Abstract
Artificial larynx, primarily of oral cavity installing mechanism, sound generating mechanism and joint mechanism composition, oral cavity installing mechanism comprises import bend pipe and entrance sleeve; Sound generating mechanism is made up of the upper cavity that pronounces, pronunciation lower chamber, pronunciation set screw, respiration valve, tibial membrane, breathing knob and collar film; Joint mechanism comprises spring handle, air inlet flap valve, controls spring, gas-tpe fitting and gas-tpe fitting pad.This utility model utilizes the expiration of patient oneself to control sound size, and can be controlled tone and the syllable of expiration sounding by breath controller and breathing knob, structure is simple, uses convenient disassembly, failure rate is low.
Description
Technical field
This utility model relates to technical field of medical instruments, is specifically related to a kind of artificial larynx of auxiliary sounding.
Background technology
The people of the Zuo Liao throat excision because of throat diseases, owing to losing vocal cords, loses the ability of speaking, causes lifelong misery.At present conventional artificial electronic larynx needs to be vibrated by musculi colli or air-flow helps sounding by oral cavity.But artificial electronic larynx also exists sounding and changes voice, machine person to person communication difficult.And the cost of artificial electronic larynx is high, fragile, use and bring many inconveniences.
Utility model content
This utility model provides a kind of artificial larynx, changes voice with the complex structure, the sounding that solve prior art existence and holds flimsy problem.
This utility model solves the technical scheme that its technical problem adopts:
A kind of artificial larynx, primarily of oral cavity installing mechanism, sound generating mechanism and joint mechanism composition, oral cavity installing mechanism comprises import bend pipe and entrance sleeve, and import bend pipe is designed to curve bend structure according to oral cavity structure, and entrance sleeve is connected to the rear end of import bend pipe, sound generating mechanism is by the upper cavity that pronounces, pronunciation lower chamber, pronunciation set screw, respiration valve, tibial membrane, breathe knob and collar film composition, pronunciation upper cavity and pronunciation lower chamber form pronunciation room, it is indoor that respiration valve is arranged on pronunciation, respiration valve arranges breath controller, respiration valve is connected with breathing knob, tibial membrane is fixed in the middle of respiration valve, tibial membrane is connected with pronunciation set screw, the tone that tibial membrane sends can be regulated by pronunciation set screw, to adapt to different sexes, the sounding of different age people needs, collar Membrane cover is connected to tibial membrane outside, joint mechanism comprises spring handle, air inlet flap valve, controls spring, gas-tpe fitting and gas-tpe fitting pad, spring handle, air inlet flap valve and control spring are arranged on gas-tpe fitting inside, air inlet flap valve is socketed on and controls on spring, spring handle is connected with control spring through air inlet flap valve, and gas-tpe fitting pad is connected to gas-tpe fitting import department.
The pronunciation upper cavity top of above-mentioned sound generating mechanism arranges hold-down ring, and hold-down ring is connected by the entrance sleeve of upper connecting tube with oral cavity installing mechanism; The pronunciation lower chamber of sound generating mechanism is connected with the gas-tpe fitting of joint mechanism by lower linking tube.
When this utility model uses, the gas-tpe fitting of joint mechanism is connected with pars cervicalis tracheae opening, and advance spring handle, open air inlet flap valve, oral cavity put into by the import bend pipe of oral cavity installing mechanism, rotates and breathes knob, and respiration valve is closed, after air-breathing, and pronunciation speech of exhaling; Time silent, rotate and breathe knob, push respiration valve open, outer extension spring handle, close air inlet flap valve, remain silent, pass through nose breathing.
This utility model utilizes the expiration of patient oneself to control sound size, and can be controlled tone and the syllable of expiration sounding by breath controller and breathing knob, structure is simple, uses convenient disassembly, failure rate is low.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, this utility model is further illustrated.
Fig. 1 is structural representation of the present utility model.
In figure, 1 import bend pipe, 2 entrance sleeves, 3 upper connecting tubes, 4 hold-down rings, 5 pronunciation upper cavities, 6 breath controllers, 7 pronunciation set screw, 8 respiration valves, 9 tibial membranes, 10 breathe knob, 11 collar films, 12 lower linking tubes, 13 spring handles, 14 air inlet flap valves, 15 control springs, 16 gas-tpe fitting pads, 17 pronunciation lower chamber, 18 gas-tpe fittings.
Detailed description of the invention
As shown in the figure, a kind of artificial larynx, primarily of oral cavity installing mechanism, sound generating mechanism and joint mechanism composition, oral cavity installing mechanism comprises import bend pipe 1 and entrance sleeve 2, import bend pipe 1 is designed to curve bend structure according to oral cavity structure, and entrance sleeve 2 is connected to the rear end of import bend pipe 1; Sound generating mechanism is made up of the upper cavity 5 that pronounces, pronunciation lower chamber 17, pronunciation set screw 7, respiration valve 8, tibial membrane 9, breathing knob 10 and collar film 11, pronunciation upper cavity 5 and pronunciation lower chamber 17 form pronunciation room, it is indoor that respiration valve 8 is arranged on pronunciation, respiration valve 8 is arranged breath controller 6, respiration valve 8 is connected with breathing knob 10, tibial membrane 9 is fixed in the middle of respiration valve 8, and tibial membrane 9 is connected with pronunciation set screw 7, and it is outside that collar film 11 is socketed on tibial membrane 9; Joint mechanism comprises spring handle 13, air inlet flap valve 14, controls spring 15, gas-tpe fitting 18 and gas-tpe fitting pad 16, it is inner that spring handle 13, air inlet flap valve 14 and control spring 15 are arranged on gas-tpe fitting 18, air inlet flap valve 14 is socketed on and controls on spring 15, spring handle 13 is connected with control spring 15 through air inlet flap valve 14, gas-tpe fitting pad 16 is connected to gas-tpe fitting 18 import department, pronunciation upper cavity 5 top of sound generating mechanism arranges hold-down ring 4, and hold-down ring 4 is connected with the entrance sleeve 2 of oral cavity installing mechanism by upper connecting tube 3; The pronunciation lower chamber 17 of sound generating mechanism is connected with the gas-tpe fitting 18 of joint mechanism by lower linking tube 12, and upper connecting tube 3 and lower linking tube 12 are plastic snake leather hose.
When this utility model uses, the gas-tpe fitting of joint mechanism is connected with pars cervicalis tracheae opening, advances spring handle, open air inlet flap valve, oral cavity put into by the import bend pipe of oral cavity installing mechanism, rotates and breathes knob in upright position, respiration valve is closed, after air-breathing, and pronunciation speech of exhaling; Time silent, rotate and breathe knob in horizontal level, push respiration valve open, outer extension spring handle, close air inlet flap valve, remain silent, pass through nose breathing.
