AI Technical Summary

Technical Problem

The elastic element design of traditional tongue muscle function recovery training devices cannot meet the rehabilitation training needs of patients from the initial to the advanced stages. The initial resistance is too high or the advanced resistance is insufficient, resulting in poor training effect.

Method used

By employing a conical spring and a nested spring structure, combined with positioning and anti-slip components, the nonlinear deformation characteristics and dynamic stiffness adjustment of the elastic element are achieved. Through the stepped stiffness change of the conical spring and the superimposed elastic force output of the nested spring, it can adapt to the training needs at different stages.

Benefits of technology

It achieves adaptive adjustment of training resistance, reduces the difficulty of starting beginner training, meets the intensity requirements of advanced patients, and improves the scientific nature and safety of training.

Abstract

The utility model relates to a training device for tongue muscle function recovery belongs to medical instrument technical field, solves the technical problem of too high initial resistance and insufficient advanced resistance caused by linear elastic element of prior art training device, the device includes handle, flexible abutting pad and training unit, the flexible abutting pad sets up at one side of handle to buffer the extrusion of handle to the palate, the training unit sets up at the other side of handle, the training unit includes support plate, conical spring and push ball, the spiral circle of the greater diameter of conical spring bottom end preferentially occurs deformation in initial compression stage, at this moment, only small thrust can complete compression, corresponding low resistance training demand of weak stage of tongue muscle strength, with the increase of compression amount, the spiral circle of gradually reducing diameter successively participates in deformation, and the overall stiffness of spring presents ladder type rise, through the stiffness of conical spring with deformation variable increment, can continuously provide the resistance matched with the tongue muscle strength growth, keeps effective muscle stimulation intensity.
