A tongue muscle pressure sensor and braces model

Abstract

The invention relates to a pressure sensor for tongue muscles. Piezoresistive strain gauges are respectively arranged at both ends of a pressing beam, and a stress pad is arranged on the piezoresistive strain gauge. The upper jaw exerts force on the stress pad, and the force pad drives the pressing beam to deform. The piezoresistive strain gauge at one end is stretched, and the piezoresistive strain gauge at the other end is compressed, which is converted into an analog voltage signal by a Huygens bridge. And a dental brace model with tongue muscle pressure detection, which is embedded with at least one tongue muscle pressure sensor. The tongue muscle pressure sensor of the present invention adopts the piezoresistive principle, and the piezoresistive strain gauge is deformed by the deformation of the beam, and converted into an analog voltage signal by a Huygens bridge for reading by a microcomputer such as a single-chip microcomputer. Compared with the prior art, the device is small in size and simple in operation and is more suitable for clinical use.

Description

technical field [0001] The invention relates to medical equipment, more specifically, to a tongue muscle pressure sensor and a mouthpiece model with tongue muscle pressure detection. Background technique [0002] As the population ages, the number of patients with cerebrovascular accidents (strokes), the leading cause of death and disability worldwide, has been increasing. According to the survey, dysphagia is a common complication of these patients, and its proportion can reach 37%-78%. Dysphagia can often cause complications such as dehydration, malnutrition, aspiration pneumonia, and psychological disorders, which is an important factor leading to the decline in the quality of life and the increase in mortality of these patients. The incidence of cerebrovascular accidents depends on the time of clinical evaluation and diagnostic method, but the above phenomenon has not yet caused enough awareness of clinicians. Therefore, timely clinical diagnosis, scientific evaluation...

Problems solved by technology

This method evaluates swallowing disorders only by observation, lacks clinical data and is only based on experience, and the operation is complicated

[0005] The swallowing disorder detection methods provided by the above two patent applications are not suitable for widespread clinical use due to the large size of the detection equipment and complicated operations.
