The invention discloses a deep learning OSA severity classification model based on vowels. The method comprises the following steps: 1, collecting vowel speech signals of a subject, wherein the vowel speech signals comprise five Chinese vowels: / a / , / o / , / e / , / i / and / u / ; step 2, obtaining an AHI index obtained after the subject is subjected to whole-night PSG, and grading the severity of the subject; and step 3, extracting four kinds of paranguage features from the voice signal, wherein the four kinds of paranguage features comprise eGemaps, emobase, ComParE16 and MRCG. Fusing the four sub-language features of the five vowels into a vowel feature graph, and providing a feature set with the best detection efficiency for subsequent training; and step 4, combining the obtained vowel feature map with baseline features (including age, BMI, height, weight, neck circumference and abdominal circumference), inputting the obtained vowel feature map into a constructed convolutional neural network (CNN) for training and testing, and obtaining classification results under different AHI severity degrees.

The application discloses a lifting adjusting device for a cervical collar, which comprises a lower jaw plate, a rear pillow support, a support plate and an adjusting assembly. The lower jaw plate is used for supporting the lower jaw of a user. The rear pillow support is used for being attached to the rear neck and the pillow part of the user. The rear pillow support is movable to adjust the distance from the lower jaw plate, and is suitable for the neck circumference of the user. The support plate is used for being attached to the shoulder and the upper chest of the user, and is used as the reaction force fulcrum of the lower jaw plate. Two sets of adjusting assemblies are connected between the support plate and the lower jaw plate. The two sets of adjusting assemblies are used for synchronously adjusting and controlling the support height of the lower jaw plate, and are locked after the adjustment and control. The continuous and stepless fine adjustment is realized. The adjusting precision is much higher than that of the traditional mode. The synchronous work of the two sets of adjusting assemblies ensures the stability and the level of the lower jaw plate in the lifting process, and avoids the problem of uneven force on one side.

The application discloses a neck massager, which comprises an intermediate support and at least one massaging head assembly. The inner side of the intermediate support is close to the skin of the human neck and is provided with a neck accommodating space. The at least one massaging head assembly is floatingly connected to the inner side of the intermediate support. The massaging head assembly comprises a massaging sheet, a massaging seat and a mounting support. The massaging sheet is suitable for being attached to the skin of the human neck and providing the human with a massaging effect. The massaging sheet comprises at least two massaging sheets. The massaging sheets are arranged on the mounting support and are adapted to the mounting support. The mounting support is swingably connected to the massaging seat. The massaging seat is floatingly connected to the inner side of the intermediate support.
