The invention relates to an elastic tongue dorsum traction apparatus and a method for implanting the same. The elastic tongue dorsum traction apparatus and the method are used for treating patients suffering from sleep apnea-hypopnea syndromes or snoring. The elastic tongue dorsum traction apparatus comprises a tongue dorsum connecting mechanism, elastic traction bodies and tooth-side fixators. A support body of the tongue dorsum connecting mechanism is implanted under the mucosa of the tongue dorsum of a patient, and the elastic traction bodies and the tongue dorsum connecting mechanism are exposed out of the mucosa of the tongue dorsum of the patient. The tooth-side fixators are fixed to the inner sides of the teeth or the alveolar bones of the patient, one end of each elastic traction body is connected with the corresponding tooth-side fixator, and the other end of each elastic traction body is connected with the tongue dorsum connecting mechanism. The elastic tongue dorsum traction apparatus and the method have the advantages that the tooth-side fixators are used as support points, the elastic traction bodies can exert elastic tractive force on the tongue dorsum connecting mechanism, accordingly, the glossocoma tongue of the patient can be pulled up forwardly, airway stenosis and obstruction of the glossopharyngeal part of the patient can be prevented, and snoring and OSAHS (obstructive sleep apnea-hypopnea syndrome) treatment effects can be realized; an elastic traction effect is realized for the tongue dorsum connecting mechanism by the elastic traction bodies, so that movement of the tongue of the patient is unaffected while the tongue of the patient is moderately pulled up, certain swallowing and speaking functions can be kept, the airway of the glossopharyngeal part of the patient can be expanded, and the patient feels comfortable when using the elastic tongue dorsum traction apparatus.

The invention relates to an obstructive sleep apnea-hypopnea syndrome (OSAHS) screening method and a device. Formant characteristics of snore are adopted as technical indexes for screening OSAHS; Snore sections are extracted by a short-time energy method at first, then LPC (linear predictive coding) is used for modeling, after predicting factors of the LPC are obtained, a first formant frequency of each snore section is obtained by a root extraction method, as ranges of formant frequencies of different modes are different, the different snore sections can be distinguished, all first formant frequencies of all snorers are classified, by the aid of K mean values, and thresholds for distinguishing normal snore and abnormal snore of individuals are determined according to classified results; and then AHI (apnea-hypopnea indexes) in a PSG (polysomnogram) are simulated so that average times of apnea and hypopnea of the snorers within an hour are obtained. According to the OSAHS judgment standard, whether the data section has snore of a normal person or snore of a patient with the OSAHS is judged. The obstruction sleep apnea-hypopnea syndrome screening method and the device are low in cost, high in applicability and simple in operation and are non-contacting.
