Embodiment 1

[0030] This embodiment provides a food simulating swallowing device, which includes a tongue base and soft tissue materials, a palate base and soft tissue materials, a micro-sensing piece, a cam link mechanism, a rack and pinion mechanism, a push rod, a motor, and the connection of these main components. A series of connecting devices, etc.

[0031] When designing the food swallowing device, the applicant extracted the curve parameters of the tongue and palate by analyzing the swallowing video, adopted curved surface modeling and selected materials reasonably so that the tongue and palate base could be manufactured using rapid prototyping technology, and the palate base The first half is made of hard materials, and the second half is made of soft materials. In the later stage, soft media such as PDMS and TPE thermoplastic elastomer materials should be covered on the second half of the palate base and the curved surface of the tongue base to simulate oral soft tissues, and the p...

Embodiment 2

[0045] This embodiment provides a method for simulating swallowing of food. The method adopts the food simulating swallowing device described in the first embodiment above for simulation, including: obtaining the curve parameters of the human tongue and palate, and according to the acquired human tongue and palate The curve parameters set the number of rack and pinion mechanisms included in the food swallowing device, the connection position between each rack and pinion mechanism and the tongue base or the slope of the rack in the rack and pinion mechanism, and use the food simulation swallowing device to simulate During the swallowing process of food in the human oral cavity, the swallowing pressure and sliding speed of the food during the swallowing process are obtained through the micro-sensing sheet.

[0046] Specifically, during the simulation process, first place a spherical food mass with a diameter of about 8-11 mm in the tongue base (2), and use the push rod I (5) to h...

Abstract

The invention discloses a food simulation swallowing device and a food simulation swallowing method, and belongs to the field of bionic mechanical design of human oral swallowing. The food simulationswallowing device includes a tongue base body and soft tissue material, an upper jaw base body and soft tissue material, a micro sensing piece, a cam connecting rod mechanism, gear rack mechanisms, apush rod, a motor, a first base, a second base and corresponding connecting devices; the gear rack mechanisms are connected to different positions of the tongue base body, and the cam connecting rod mechanism is connected to the root of tongue of the tongue base body. Through the gear rack mechanism and the cam connecting rod mechanism, the real dynamic simulation of a tongue in the process of swallowing can be realized, the in vivo measurement data of food flow and a swallowing system can be obtained when swallowing is carried out, the length of a connecting rod, the speed and angle of the gear rack can be changed to adapt to swallowing curves of different people, and thus the adaptability is better. The food simulation swallowing device and the food simulation swallowing method are of great significance to study the flow characteristics of food and treat dysphagia with relative safe foods.

Description

technical field [0001] The invention relates to a food simulating swallowing device and a food simulating swallowing method, which belong to the field of bionic mechanical design of human oral cavity swallowing. Background technique [0002] Dysphagia is dysphagia caused by various reasons and can occur in different parts of swallowing. Dysphagia can affect food intake and nutrient absorption, and can also lead to aspiration pneumonia caused by food being inhaled into the trachea. In severe cases, it is life-threatening. Invasive medical equipment is used to obtain in vivo information of patients, but it is not easy to obtain in vivo measurement data of food flow and swallowing system during swallowing, which directly leads to the inability to prescribe the right medicine in medicine, and hinders the research on the influence of food material characteristics on the swallowing process and the safety of food development. [0003] In order to improve the level of medical diag...
