The present invention relates to a biodegradable, absorbable stent comprising a skeletal structure made of a metallic alloy of magnesium and a transition metal and / or a rare earth element. The skeletal structure is coated with a polymer, and the coated skeletal structure has struts of stent elements, and the stent may be a valve support stent. Furthermore, the present invention relates to the use of a disclosed valveless stent, or a system comprising a corresponding stent, for implantation in congenital heart disease to open the pulmonary artery, to maintain patency of the ductus arteriosus (ductus of Botallo), to maintain patency of aortic isthmus stenosis, to stimulate growth in a hypoplastic pulmonary artery, or as an esophageal stent or ureteral support.

The present invention relates to a smart mirror-based health-training coaching system and an operating method thereof. The present invention is advantageous in that a user can exercise in a user's dedicated space at a required time according to a selected type of training by using a smart mirror and following trajectories of respective skeletal structures during training by a professional health trainer, and the accuracy of the training can be analyzed and training in a specific interval can be selected and repeatedly performed.

This utility model provides a ship auxiliary support device, relating to the field of auxiliary support technology, for installation within the abdominal cavity of a ship's skeletal structure. The auxiliary support device includes: two support seats disposed within the abdominal cavity and respectively connected to two surfaces of the skeletal structure; a pressure sensor disposed on one of the support seats and connected to one surface of the skeletal structure; and a telescopic component, with both ends hinged to the two support seats. The telescopic component and the pressure sensor are signal-connected to the ship's control unit. The pressure sensor can send pressure signals to the control unit, which can control the telescopic length of the telescopic component based on the pressure signals. This auxiliary support device effectively solves the problems of poor stability and unadjustable support force of traditional wooden wedge supports, extends the service life of the structure, improves the ship's operational efficiency, and enhances the ship's operational safety.

This invention relates to the field of oral medical diagnostic and identification technology, and provides a decision-making method and system for maxillary arch expansion diagnosis and expander selection. The method includes: S1: acquiring and verifying multiple mandatory parameters such as dentition stage, patient age, transverse width of maxillary and mandibular teeth, transverse width of maxillary and mandibular skeletal structure, bone or tooth expansion requirements, and midpalatal suture stage; S2: performing anchorage determination based on dentition type to obtain anchorage status; S3: inputting the structured parameter set into a hierarchical decision tree algorithm, using whether the bone or tooth expansion requirements have reached a preset activation threshold as the initial judgment condition, matching decision branches layer by layer according to a preset priority order, and arbitrating according to the anchorage safety priority rule when multiple candidate schemes conflict, outputting a maxillary arch expansion scheme; S4: outputting the maxillary arch expansion scheme and its corresponding judgment basis. This solves the problems of subjective judgment of midpalatal suture maturity, inaccurate estimation of skeletal and dental expansion amounts, and lack of a unified standard for assessing anchorage conditions at different dentition stages.

A sleep apnea device for positioning the neck and jaw of a user, the device including a skeletal structure and a cushioning structure. The skeletal structure includes a lower section, an upper section including at least one support, and a plurality of longitudinal rods. The cushioning structure includes a rear portion and side portions, and defines at least one cavity, a plurality of longitudinal bores, and an upper surface. The lower section of the skeletal structure is disposed within the cavity of the cushioning structure, and the upper section of the skeletal structure is disposed above the upper surface of the cushioning structure. Each longitudinal rod in the plurality of longitudinal rods extends through a corresponding one of the plurality of longitudinal bores to connect the upper section with the lower section of the skeletal structure.
