The present invention relates to an organ simulation apparatus, and more particularly, to an organ simulation apparatus for verifying a medical apparatus for examining an internal organ of a human body.

Conventionally, in developing an endoscope or capsule endoscope that examines the internal organs of a human body, animal experiments such as pigs, dogs, and rabbits were performed to examine the performance of the medical device. However, these animal experiments were difficult to prepare and costly, and the time to perform the experiment was very limited, making it difficult to efficiently check and improve the performance of medical devices.

An alternative is to conduct experiments using organs from dead animals. However, the internal organs of the human body are formed of soft tissues, and the food flowed through the mouth performs peristalsis so as to escape to the anus through the esophagus, stomach, duodenum, small intestine, large intestine, and rectum. Therefore, the method of performing the experiment using the organs of the dead animal is disadvantageous because the experiment in the situation that the peristaltic movement is not made and the reliability of the experimental results is low.

The present invention has been made to solve the above problems, it is possible to reduce the cost by allowing the laboratory to test the performance of the medical device, model organs, long-term simulation that can increase the reliability of the experiment by simulating living organs It is an object of the present invention to provide a method of controlling a device and a long-term simulation device.
