Embodiment Construction

[0025] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.

[0026] Such as figure 1 , figure 2 , image 3 As shown, the tongue muscle pressure sensor of the present invention includes: a silicone pad 10, a mask 11, a pressure beam 12, a force pad 13, a support frame 14, a fixing washer 15, and a piezoresistive strain gauge.

[0027] The piezoresistive strain gauges are respectively arranged at both ends of the pressing beam 12, and the piezoresistive strain gauge is provided with a stress pad 13, the upper jaw exerts force on the stress pad 13, and the force pad 13 drives the compression beam 12 to deform, and the piezoresistive strain at one end The sheet is stretched, and the piezoresistive strain gauge at the other end is compressed, and converted into an analog voltage signal through the Huygens bridge. The piezoresistive strain gauge as a sensitive force-bearing element of the tongue muscle pr...

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...
