Abstract
The utility model provides a throat sounding device, which belongs to the technical field of medical instruments. The device is characterized in that the upper end of an air storage cover is matched and connected with a base with a through hole; an interface at the upper end of the base is connected with a sound guide pipe; the lower part of the base is provided with a sounding band connector having a corresponding through hole; the end face of the sounding band connector is matched and provided with a sounding band; and the front of the sounding band inside a cavity of the air storage cover is matched and provided with a sound amplifying ring, so as to divide the air storage cover into a resonant chamber and an air storage chamber. The device is ingenious in conception, simple and reasonable in structure, free from operation and convenient to use. The device adopts the physical sounding theory of adhesive film vibration, namely, the air storage chamber is full of air; the air is led into the resonant chamber through the sound amplifying ring so as to drive the sounding band to sound; the sound enters an oral cavity through the sound guide pipe, and then a tongue acts in concert with lips for speaking; and the device is clear in sound and natural in timbre. With no battery needed, the device has the advantages that the device is more economical, friendly to environment, small in volume, light in weight and convenient to carry.
Description
Technical field
This utility model belongs to technical field of medical instruments, is specially the larynx tone generator.
Background technology
Patients with laryngeal carcinoma has just lost function of pronunciation after implementing total laryngectomy, and it is maximum misery that postoperative can not pronounce, and for the patient who makes the full resection operation larynx of larynx recovers pronunciation function in a minute, has invented tone generator.The tone generator that uses mainly contains two kinds at present: a kind of is electronic larynx, and also having a kind of is built-in pronunciation tube.The deficiency of electronic larynx is to cost an arm and a leg, and sound is low, needs often to change battery, and general patient holds and dares not accept.Built-in pronunciation tube must be performed an operation to patient and is installed in throat, infects easily in the use, and voice effect is poor, and service life is short, and when changing or cleaning, must operate to the patient once more, increases a lot of miseries to patient.
The utility model content
At the above-mentioned problems in the prior art, the purpose of this utility model is to design the sonorific technical scheme of the larynx that a kind of external use is provided, and it is easy to use, and cost is low, and volume is little, and is in light weight, easy to carry.
Described larynx tone generator, it is characterized in that the storage cover upper end and the pedestal of band through hole are connected, end interface is connected with sound guide tube on the pedestal, the pedestal bottom connects the phonatory bands union joint that setting has respective through hole, be equipped with phonatory bands on the phonatory bands union joint end face, storage cover intracavity phonatory bands the place ahead is equipped with the circle that amplifies, and storage cover is divided into resonant chamber, air storage chamber.
Described larynx tone generator is characterized in that the socket of sound guide tube upper end is provided with the pronunciation flexible pipe.
Described larynx tone generator is characterized in that storage cover and pedestal, pedestal and phonatory bands union joint threaded respectively.
Described larynx tone generator is characterized in that phonatory bands is connected on the phonatory bands union joint end face by collar.
Described larynx tone generator is characterized in that phonatory bands union joint leading section is a bowl structure, and the bowl end degree of depth is 0.5～8mm, is preferably 1～5mm.
Described larynx tone generator, the bottom balling-up globoidal structure of the circle that it is characterized in that amplifying, the spherical cambered surface top is provided with through hole.
Described larynx tone generator is characterized in that phonatory bands adopts foil, silica gel or rubber to make.
Above-mentioned larynx tone generator is skillfully constructed, and is simple and reasonable for structure, and external use need not be performed the operation, and is easy to use.Adopt the physics pronunciation principle of glued membrane vibrations, air is full of air storage chamber, imports resonant chamber by the circle that amplifies, and drives the phonatory bands pronunciation, and sound enters the oral cavity by sound guide tube, cooperates speech by tongue and lip again, its lamprophonia, tone color nature.This larynx tone generator is because without battery, more economical, environmental protection, and volume is little, and in light weight, carry easily.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is this utility model surface structure sketch map;
Among the figure: 1-pronunciation flexible pipe, 2-sound guide tube, 3-pedestal, 4-phonatory bands union joint, 5-phonatory bands, 6-amplify circle, 7-storage cover, 8-air storage chamber, 9-resonant chamber, 10-collar.
The specific embodiment
The utility model is described in further detail below in conjunction with Figure of description:
As shown in the figure, storage cover 7 upper ends are connected with the pedestal 3 of band through hole, end interface is connected with sound guide tube 2 on the pedestal 3, pedestal 3 bottoms connect the phonatory bands union joint 4 that setting has respective through hole, storage cover 7 and pedestal 3, pedestal 3 and phonatory bands union joint 4 difference threaded, pedestal 3 also can be integrally formed with phonatory bands union joint 4, and corresponding through hole is communicated with the formation sound-delivery channel.Be equipped with phonatory bands 5 on phonatory bands union joint 4 end faces, phonatory bands 5 is connected on phonatory bands union joint 4 end faces by collar 10, phonatory bands 5 adopts foil, silica gel or rubber to make, phonatory bands union joint 4 leading sections are bowl structure, the bowl end degree of depth is 0.5～8mm, be preferably 1～5mm, unsuitable too small, phonatory bands 5 vibrations easily touch phonatory bands union joint 4 bottom surfaces and can't pronounce during because of speech.Storage cover 7 intracavity phonatory bandses 5 the place aheads are equipped with the circle 6 that amplifies, and storage cover 7 is divided into resonant chamber 9, air storage chamber 8, and sound guide tube 2 upper end sockets are provided with pronunciation flexible pipe 1, the bottom balling-up globoidal structure of the circle 6 that amplifies, and the spherical cambered surface top is provided with through hole.
Pedestal 3 adopts medical stainless steel, titanium alloy, medical silica-gel, plastics, packfong, ferrum or carbon fibre reinforced plastic to make.Phonatory bands 5 adopts foil, silica gel or rubber elastomeric material to make.
