Abstract

The invention provides a digestive tract system simulation device, which includes a simulated oral cavity, a simulated esophagus, a simulated stomach, a simulated small intestine, a simulated large intestine, and a simulated anus and switches thereof; There are acid storage chambers, buffer storage chambers, digestive enzyme storage chambers, lye storage chambers and their flow controllers, as well as sensors for pH, pressure and enzymes; the central control unit is used to set the overall parameters of the simulated digestive tract , receive the detection results fed back by the sensor, adjust the flow controller, analog switch, electric control driver action range and action duration, etc., and save various parameters in the data storage unit, and output through the data output interface. The invention can simulate the peristaltic action of the digestive tract, and can achieve the purpose of controlling the running time of the simulated digestive tract through the control of the action range and action time. It has the advantages of simple system structure, long working time, many simulation parameters and comprehensive functions.

Description

technical field

[0001] The present invention relates to a digestive tract system simulation device, in particular to a device for simulating the physiological function state of the digestive tract, which can continuously adjust the pH value, pressure, enzymes, etc. inside the digestive tract, and can simulate the peristalsis of the digestive tract . Background technique

[0002] In today's society, people's life pressure is increasing, and gastrointestinal diseases are also increasing. Correspondingly, there are more and more instruments for the diagnosis, treatment and monitoring of gastrointestinal diseases. However, because such instruments generally belong to the second and third types of medical instruments, so Corresponding human clinical trials are required. In order to reduce the risk of clinical trials and find product shortages and hidden dangers early, technicians in the field hope that through a simulation device, on the one hand, they can strengthen their under...
