Description

Pronunciation training device

Technical Field

The utility model belongs to the technical field of medical appliances, and particularly relates to a pronunciation training device.

Background

The laryngeal cancer is mainly treated by surgery, along with the continuous development of head and neck surgery technology, the excision of lesion parts and the reservation of laryngeal functions as much as possible become the leading factor of laryngeal cancer surgery, but the postoperative pronunciation dysfunction becomes a more common problem due to the change of the local anatomical structure of the laryngeal and the need of wearing a tracheotomy sleeve by a patient, and is mainly characterized by laborious pronunciation, poor consistency, low volume, weakened speaking rate, incapability of communicating with people normally and serious influence on the life quality of the patient. Medical staff needs to accurately evaluate the pronunciation of the patient after the laryngectomy, and accurately judge the pronunciation problem of the patient so as to improve the pronunciation condition of the patient and the life quality of the patient.

Normal pronunciation actions are instantaneously completed, and the coordination of the oral cavity, the pharyngeal portion, the trachea and the lung is needed. In the laryngeal partial excision, a part or double-sided vocal cords, ventricular bands and/or epiglottis and arytenoid epiglottis folds are often required to be excised, and even one-sided arytenoid cartilage is excised, so that the anatomical structure of the postoperative larynx is changed, the laryngeal cavity is lost to be in a normal shape, becomes a round shape, an oval shape or an irregular shape, and a patient needs to wear a tracheal cannula, so that the pronunciation quality is often obviously reduced, and the laryngeal is mainly hoarse and sunken in clinic. The pronunciation effect of the throat after the operation has great influence on the social function and psychological state of the patient. Studies indicate that whether dysarthria occurs after head and neck tumor surgery is closely related to the surgical excision site, scope and structural reconstruction mode. Therefore, the smoothness of the patient's pronunciation air flow and the air flow size are critical to pronunciation.

The inner sleeve 2 is arranged in the lumen of the outer sleeve 1, the fixed wing 3 is sleeved at the air inlet end of the outer sleeve 1, a first air outlet 11 and a second air outlet 21 are respectively arranged at preset positions of one sides of the outer sleeve 1 and the inner sleeve 2 facing the glottis, the positions of the first air outlet 11 and the second air outlet 21 are arranged in a radial opposite mode, and an adjusting part for adjusting the opening of the first air outlet 11 is arranged at the position of the first air outlet.

In the utility model, the positions of the first air outlet 11 and the second air outlet 21 correspond to glottis areas, and when in expiration, air flows impact on the vocal cords from the two air outlets, so that a patient can pronounce, and meanwhile, the first air outlet 11 is provided with an adjusting part for adjusting the opening degree of the adjusting part, so that the requirements of different patients on the flow of the pronouncing air flow are met.

The pronunciation training device of the present utility model is suitable for patients with laryngeal incision. In use, the outer sleeve 1 and the inner sleeve 2 of the present utility model are inserted into the throat of a patient and secured by the securing wings 3, wherein the end of the outer sleeve 1 and the inner sleeve 2 exposed outside the throat is the air inlet end.

Specifically, the first air outlet 11 is 1/3 to 1/2 of the length of the outer sleeve 1 from the air inlet end of the outer sleeve 1; likewise, the second air outlet 21 is spaced from the air inlet end of the inner sleeve 2 by 1/3 to 1/2 of the length of the outer sleeve 1.

In one embodiment, the adjusting means comprise an adjusting plate 4 and a push-pull rod 5. At least a part of the adjusting plate 4 can cover the first air outlet 11, the extending direction of the push-pull rod 5 is the same as that of the outer sleeve 1, one end of the push-pull rod 5 is arranged in the fixed wing 3 in a penetrating way, and the other end of the push-pull rod is connected with the adjusting plate 4. Wherein, the push-pull rod 5 can drive the adjusting plate 4 to reciprocate along the extending direction of the inner sleeve 2 so as to adjust the opening of the first air outlet 11.

Specifically, the adjusting plate 4 is set to be arc-shaped, and the radian of the adjusting plate 4 is the same as the radian of the pipe wall of the outer sleeve 1, so that the adjusting plate 4 can be tightly attached to the pipe wall of the outer sleeve 1, thereby better realizing the effect of adjusting the opening size of the second air outlet 21.

Further, the adjusting plate 4 and the push-pull rod 5 are both arranged on the inner wall of the outer sleeve 1. In other words, the adjusting plate 4 and the push-pull rod 5 are both arranged between the inner sleeve 2 and the outer sleeve 1 for easy installation.
