Throat CA postoperative sounding device

Abstract

A larynx CA postoperative vocal apparatus belongs to the medical apparatus technical field, and is characterized in that an upper end of an air storage cover is connected and engaged with a base which has a through-hole, an interface arranged on the upper end of the base is connected with a sound pipe, a vocal band connector with the corresponding through-hole is connected and arranged on the lower portion of the base, a vocal band is cooperatively arranged on the end face of the vocal band connector, a sound-amplification ring is cooperatively arranged in front of the vocal band in a cavity of the air storage cover, and the air storage cover is divided into an acoustic resonance chamber and an air storage chamber. The larynx CA postoperative vocal apparatus has the advantages of ingenious construction, simple structure, rationality, and convenient utilization, and can be externally used without the need of operations. The physical phonic principle of the organic film base vibration is adopted, the air storage chamber is filled with air, the air is led into the acoustic resonance chamber through the sound-amplification ring for driving the vocal band to pronounce, the voice enters into an oral cavity through the sound pipe and then a tongue and lips are engaged to speak, and the voice is clear and the tone color is natural. Because the larynx CA postoperative vocal apparatus does not need batteries, the vocal apparatus is more economical and environment-friendly, small in bulk, light in weight, and much portable.

Description

technical field [0001] The invention belongs to the technical field of medical devices, in particular to a sounder after laryngeal CA surgery. Background technique [0002] After total laryngectomy, patients with laryngeal cancer lose their pronunciation function. The inability to speak after surgery is the greatest pain. In order to restore the pronunciation and speaking function of patients who underwent total laryngectomy, a pronunciation device was invented. There are two main types of pronunciation devices currently in use: one is an electronic throat, and the other is a built-in pronunciation tube. The disadvantages of the electronic larynx are that it is expensive, the sound is low, and the battery needs to be replaced frequently, which is unaffordable for most patients. The built-in sounding tube must be installed on the patient's larynx after surgery. It is prone to infection during use, the sound effect is poor, and the service life is short. When replacing or cle...

Problems solved by technology

The disadvantage of electronic laryngeal is that it is expensive, the sound is low, and the battery needs to be replaced frequently, which is unaffordable for ordinary patients.

The built-in pronunciation tube must be operated on the patient and installed in the throat. It is prone to infection during use, the pronunciation effect is poor, and the service life is short. When it is replaced or cleaned, the patient has to be operated again, which adds a lot of pain to the patient.
