Trachea esophagus vocalization for indwelling one-way valve hand prosthesis operation unnecessary

摘要

(57) Artificial organs for trachea esophagus vocalization living patients who received [summary] laryngectomy is not a hands-A (20), the artificial organ (20), and support (21) one-way valve and a (23, 24) means, said one-way valve (14), small extending from the patient''s skin is surgically formed in the front wall (14) in the patient''s trachea (22) (15 is possible to arrange) within, allowing to (14) within the trachea said one-way valve (21) the passage of air through it, but allows the passage of air to the outside small (15) trachea (14) Without the said support means (23, 24), attached to (21) the one-way valve, and extends laterally from said one-way valve (21), said support means (23, 24, is adapted to contact the front mucosa (14) of the tracheal stoma (15) around (22), whereby, 27) is air-tight between the one-way valve (21) and the tracheal mucosa (22) to achieve a seal, and to support a predetermined position (15) in the small of the one-way valve (21), whereby the artificial organ (20), expiratory said small and (21) one-way valve The prevented from passing out of the (15), and, to allow the passage of air to the pharynx trachea (14), the one-way tracheoesophageal to block the passage trachea to (14) from the throat of the food By via (16) valve means, is fed into the pharynx and the exhaled air, and the prosthesis is characterized in that it is possible to obtain a tracheoesophageal speech without a hands.
