Tongue muscle pressure sensor and tooth socket mold

Abstract

The invention relates to a tongue muscle pressure sensor. The two ends of a pressing piece beam are provided with piezoresistance strain gauges respectively. Stress pads are arranged on the piezoresistance strain gauges. The upper jaw applies force to the stress pads, and the stress pads drive the pressing piece beam to deform. The piezoresistance strain gauge at one end is stretched, the piezoresistance strain gauge at the other end is compressed, and analog voltage signals are obtained by conversion through the Huygens electric bridge. The invention further relates to a tooth socket mold with the function of tongue muscle pressure detection. At least one tongue muscle pressure sensor is embedded into the tooth socket mold. According to the tongue muscle pressure sensor, the piezoresistance principle is adopted, the piezoresistance strain gauges are driven by deformation of the beam to deform, and the analog voltage signals are obtained by conversion through the Huygens electric bridge so as to be read by microcomputers like a single chip microcomputer. Compared with the prior art, the tooth socket mold is small and exquisite in size, easy to operate and better applicable to 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.
