Problems solved by technology

However, the device has the following problems: first, the device is mainly designed for the drug release rate, and only simulates the pH value and drug delivery time; second, it only simulates a certain part of the digestive tract through several separate decomposition pools; In addition, for pressure, the parameters of digestive enzymes are not involved, and the simulation of digestive tract peristalsis function cannot be performed

Embodiment Construction

[0024] The present invention will be further described below in conjunction with specific examples.

[0025] As shown in FIG. 1 , the digestive tract simulation device of the present invention includes a simulated oral cavity 1 , a simulated esophagus 3 , a simulated stomach 10 , a simulated small intestine 13 , a simulated large intestine 16 and a simulated anal opening 17 arranged in a shell 35 in sequence. The overall appearance of the shell 35 is about 45×25×65 cm in length, width and height, the simulated esophagus is about φ2.0×20 cm, the simulated stomach capacity is about 1500 ml, the simulated small intestine is about φ2.0×500 cm, and the simulated large intestine It is about φ3.0×100 cm, the volume of several liquid storage chambers is about 1000 milliliters, and the volume of waste liquid recovery tank is about 3000 milliliters.

[0026]A simulated throat switch 2 is provided in the simulated oral cavity 1, a simulated cardia switch 5 is provided at the connection b...

Abstract

A simulation device of alimentary canal consists of simulated oral cavity, simulated oesophagus, simulated stomach, simulated small intestine, simulated big intestine, simulated anus and its switch, motor actuators set separately in said simulated organs, acid liquor storage chamber, buffer liquor storage chamber, digestive enzyme storage chamber, alkali liquor storage chamber, flow rate controllers set separately in said chambers, transducers of pH value and pressure as well as enzyme. It is featured as using central control unit to control said actuators and to set various parameters of complete alimentary canal.

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...
