An ornamental design for a facial exercise device, as shown in the figures and description. The facial exercise device is used to strengthen, tighten, and tone the midface, lower face, orofacial region, and oropharynx (including the tongue and floor of the mouth muscles) for both aesthetic and rehabilitative therapeutic purposes. The facial exercise device comprises a trapezoidal tubular body having a primary isosceles trapezoidal shape. The trapezoidal tubular body defines a plurality of openings with equally spaced compressible and bendable body members centered around a central opening, positioned at predetermined locations for isometric and isotonic muscle resistance training for various facial and tongue movements. The facial exercise device can be positioned anywhere, including under the lower lip, under the upper lip, under both lips, on one or both cheeks, around the outer periphery of the mouth, and within the oral cavity (contacting the hard palate, tongue surface, and floor of the mouth). 1.1) Perspective view; 1.2) Front view; 1.3) Plan view; 1.4) Bottom view; 1.5) Right side view; 1.6) Left side view; 1.7) Rear view; 1.8) Cross section; 1.9) Reference view showing the state of use; 1.10) Reference view showing the state of use

This utility model discloses a palatal support occlusal oral device, comprising an upper dental brace and a palatal support. The upper dental brace has a structure that engages with the upper teeth, including the buccal surface, lingual surface, and occlusal surface of the upper teeth. The palatal support includes a hard palate region corresponding to the hard palate and a soft palate region corresponding to the soft palate. Pressure sensors are respectively provided on at least the occlusal surface of the upper teeth and on both the hard and soft palate regions. This utility model, by placing sensors at multiple points on the tongue, palate, and occlusal surface, can detect pressure data at multiple points, thereby enabling coordinated analysis of multi-stage chewing and swallowing movements.

The invention provides a multi-view face image processing system, and relates to the technical field of image processing. The system comprises an image acquisition module used for shooting a front side face image, a first mouth image and a second mouth image; the preprocessing module is used for performing normalization and illumination enhancement on the multi-view face image; the feature quantitative calculation module is used for generating geometric features such as mandibular bones, tongue space ratio, neck-to-face ratio, facial geometric contour and eyelid texture based on the processed front and side face and first mouth image; the deep learning reasoning module is used for generating semantic features such as hard palate form probability distribution, tonsil grading, occlusal relationship and nose wing form based on the processed side face image, the first mouth image and the second mouth image; and the multi-modal feature fusion module is used for carrying out weighted fusion and nonlinear mapping on the geometric and semantic features and the physiological parameters of the user to obtain a fusion feature map. According to the invention, sleep apnea prediction is carried out directly based on the fused feature map, and the prediction efficiency and prediction precision of sleep apnea are improved.

The invention discloses an auxiliary supporting type nasal oxygen cannula suitable for a patient suffering from bucktooth and incisor tooth loss, and relates to the technical field of nasal oxygen canals, the auxiliary supporting type nasal oxygen cannula comprises a nasal oxygen cannula main body and an oral cavity supporting assembly, and the oral cavity supporting assembly is connected with the nasal oxygen cannula main body through a buckle type connecting assembly; the oral cavity supporting assembly comprises an adjustable occlusal pad and a plurality of anti-slipping buckles evenly arranged on the adjustable occlusal pad, the whole adjustable occlusal pad is of an arc-sheet-shaped structure, and the radian of the arc-sheet-shaped occlusal pad can be adjusted. The anti-slip buckle is used for hooking a gingival groove and abutting against the hard palate so as to fix the adjustable occlusal pad. According to the invention, the conversion from face fixation to stable support in the oral cavity is realized through structural innovation, a safe, comfortable and stable oxygen supply solution is provided for patients with abnormal tooth structures, the treatment compliance and life quality are remarkably improved, and the device has important clinical application value.

The invention relates to the technical field of stomatology, in particular to a method and system for measuring the bone mineral density ratio of a palate center seam, and the method comprises the steps: firstly obtaining the cross section slices of the palate center seam, the hard palate and the soft palate, and then segmenting the slices through a pre-trained image segmentation model to obtain the bone mineral density ratio of the palate center seam; and respectively extracting a palate center seam region, a hard palate region and a soft palate region. Then, extracting a first target region, a second target region and a third target region from the regions according to a specific rule, and calculating the density ratio of the palate center seam based on parameters such as gray values of the target regions; in the extraction process, through the measures of setting boundary constraints, screening abnormal areas and the like, the accuracy and reliability of extraction are ensured, the measurement efficiency is remarkably improved, the measurement time is shortened, errors caused by manual measurement are reduced, meanwhile, a rapid and accurate diagnosis reference is provided for clinicians, especially new dentists with insufficient experience, and the accuracy and the reliability of extraction are improved. And the efficiency and accuracy of clinical work and research work are improved.
