Description
Technical field
The present invention relates to a kind of electronic larynx gas sounding accessory system, belong to field of medical technology.
Technical background
If middle and advanced stage laryngocarcinoma involves vocal cords, vocal cords can not then retain, and need row total laryngectomy；And vocal cord vibration and larynx and mouth
The transmission of airstream vibration between pharynx is the most basic and important language forming process.Lose vocal cords and complete air-flow is passed
Send passage so that patients with laryngocarcinoma after operation can not autonomous sounding, had a strong impact on the quality of life of postoperative patient.
For the reconstruction of Laryngectomy sounding, the continuous exploratory development of people also fails to find and recovers sounding energy completely
The method of power；Mainly there are following several vocal techniques at present：
1st, esophageal phonation method is in the stage without machinery or the help of instrument, and oesophagus sounding is almost larynx and cuts patient's " speaking " entirely
Unique channel, the principle of this method be using the pleat of postoperative throat or the introitus oesophagi of constriction as " replacement vocal cords ", with
Chest pressure and cricopharyngeus shrink the traction force as " replacement vocal cords ", and air-column vibration in oesophagus is caused by way of belch
Fundamental tone is produced, then processes by pharynx, nose, mouth, tongue, lips and teeth composition language.
This method is as the more original postoperative method of voice production, it is necessary to which patient is greatly patient and willpower receives system
Guidance admits air into oesophagus to master the technique to complete subsequent process；And short wind, or soft tissue scar formation all
It is likely to become the bad condition for hindering sounding.The sound sent is different usually more indistinct discontinuous due to own bodies condition.
2nd, voice reconstruction operation tracheae fistulization：Such a method is to carry out fistulization suture with one section of mucous membrane of esophagus and tracheae
The sounding passage replaced is formed, such a method operating difficulty is smaller, but because fistulization size is difficult to accurate control, it is postoperative to oesophagus
Food passageway inhales the risk of infection, is usually unsuccessfully difficult to reach sounding effect by mistake in addition there may be obstacle；And for invading model
Enclosing more extensively needs the patient of resection of esophageal, is even more to realize.As the improvement of this art formula, replaced with hollow silicone rubber tube by eating
The sounding passage of pipe mucous membrane formation, improves the success rate of technique to a certain extent, but rubber tube replacement frequency is higher,
Rubber tube will be changed by modus operandi within 1 ~ 2 year.
3rd, external mechanical larynx
（1）Reed-type artificial larynx：It is the role that reed or rubber membrane are served as to removed vocal cords, is placed in that throat laryngocarcinoma is postoperative to be opened
At mouthful, fundamental tone is produced by its airstream vibration diaphragm being open, then oral cavity is admitted to together with air-flow by the transmission of rubber tube
Rear portion carries out language processing, produces language.But it also has the limitation of oneself, it is necessary to which to pacify chaffy box cover tight with otch
Closely connected conjunction reaches flow conductance and the effect of vibrating diaphragm, and the full larynx of laryngocarcinoma cuts to obtain patient, it is impossible to it is required that otch reaches same chi
Very little regular otch, can cause gas leakage, it is impossible to reach sounding effect with cover box stickiness difference.
（2）Artificial electronic larynx：It is, using battery as power, the electronics that lasting buzzing causes tissue vibration to be sent by one
Device is fixed on neck more gentle soft position, causes the air concussion of bottleneck throat by shaking tissue to produce sound wave then
Oropharynx restructuring language.Such a mechanical sounding link up, can long-time sounding, to postoperative patient physical qualification without particular/special requirement；But
Need patient to vacate a hand electronic vibration device is tightly fastened in neck to ensure smoothly to vibrate throat's air；Need to also be in sounding
When synchronous controlling switch, with the readability for mitigating voice and improving language, and be used as and assist sounding instrument, its cost compared with
Height, many postoperative patient economic conditions can not be born.
The content of the invention
To overcome the defect of prior art, the technical problem to be solved in the present invention is by mini type gas sensor control
The rotating speed of EAP Electronic Air Pump is so as to the accessory system of sounding.
The technical solution adopted by the present invention is：A kind of electronic larynx gas sounding accessory system, including mini type gas sensor,
A/D modular converters, PWM generation modules, controlled electron air pump, the artificial throat of reed and airway tube；Mini type gas sensor is put
At the postoperative opening of throat laryngocarcinoma, the flow velocity and flow parameter of gas in mini type gas sensor measurement trunnion, and export relative
The analog signal answered；The analog signal is passed into A/D modular converters, A/D modular converters convert analog signals into expression
The data signal of gas flow rate and flow；PWM generation modules generate pulse width PWM ripples according to data signal；PWM ripples are made
For control signal, according to the rotating speed of different Duty ratio control controlled electron air pumps, so as to produce and gas flow rate, stream in trunnion
Measure identical air-flow；After the air-flow of controlled electron air pump output is by the artificial throat of reed, oral cavity hair is entered back into airway tube
Sound.
The beneficial effects of the invention are as follows：This electronic larynx gas sounding accessory system includes mini type gas sensor, A/D and turned
Change the mold block, PWM generation modules, controlled electron air pump, the artificial throat of reed and airway tube；Mini type gas sensor is placed in throat larynx
At the postoperative opening of cancer, the flow velocity and flow parameter of gas, obtain analog signal in measurement trunnion；A/D modular converters, which will be simulated, to be believed
Number it is converted into representing the data signal of gas flow rate and flow；Data signal is generated pulse width PWM ripples；The control of PWM ripples can
The rotating speed of EAP Electronic Air Pump is controlled, so as to produce and gas flow rate, flow identical air-flow in trunnion；Oral cavity is entered back into airway tube
Sounding.The electronic larynx gas sounding accessory system has low cost, and durability is good, does not result in the superinfection of patient, is applicable
All kinds of throat patients with laryngocarcinoma after operation.
Brief description of the drawings
Fig. 1 is a kind of electronic larynx gas sounding accessory system fundamental diagram.
Embodiment
Below in conjunction with accompanying drawing 1, the present invention will be further described, and this electronic larynx gas sounding accessory system includes miniature
Gas sensor, A/D modular converters, PWM generation modules, controlled electron air pump, the artificial throat of reed and airway tube.By miniature gas
Body sensor is placed at the postoperative opening of throat laryngocarcinoma, and the flow velocity and flow parameter of gas, export corresponding mould in measurement trunnion
Intend signal value；The analog signal of mini type gas sensor is passed into A/D modular converters again, the analog signal of acquisition is converted into
Represent the data signal of gas flow rate and flow.PWM generation modules generate pulse width modulation wave according to the data signal（PWM
Ripple）；Using PWM ripples as control signal, according to the rotating speed of different Duty ratio control controlled electron air pumps, so as to produce and trunnion
Middle gas flow rate, flow identical air-flow；After the air-flow of controlled electron air pump output is by the artificial throat of reed, into airway tube
Enter back into oral cavity.
