The present invention relates to a test capsule device, a position signal receiving device of the test capsule device, a test capsule device and a system having a position signal receiving device thereof, and an operating method of a system having a test capsule device and a position signal receiving device thereof. In more detail, a capsule device for testing used for testing before use of a capsule endoscope for imaging internal organs of the human body, a location signal receiving device of the capsule device for testing, a capsule device for testing, and a location signal receiving device thereof. A system and a method of operating the system having a capsule device for testing and a device for receiving a position signal thereof.

Recently, the use of capsule endoscopy is increasing to overcome the disadvantages of general endoscopy. Capsule endoscopy generally has a pill shape, and has the advantage of being able to minimize the objection and pain of the examinee, as well as being able to identify lesions in the small intestine that are difficult to access compared to general endoscopy.

Here, in the method of examining the internal organs of the human body using the capsule endoscope, when the subject swallows the capsule endoscope through the oral cavity, images are captured while cruising the esophagus, stomach, small intestine, and large intestine inside the human body. An image captured by the capsule endoscope is transferred to an external receiver through various wireless communication methods such as RF communication and human body communication. The capsule endoscope is inserted into the human body through the oral cavity of the human body and cruises through the esophagus, stomach, small intestine, and large intestine to capture images and then discharges them through the anus.

On the other hand, in the course of the capsule endoscope photographing the internal organs of the human body and discharging them through the anus, the capsule remains in the human body without being discharged to the outside of the human body depending on the subject. In addition, a regional transit abnormality (RTA) phenomenon in which the capsule endoscope is temporarily not discharged occurs.

In detail, the residual phenomenon of the capsule endoscope is defined as when the capsule endoscope is not spontaneously discharged from the gastrointestinal tract for more than 2 weeks after being inserted into the human body. The RTA phenomenon of capsule endoscopy is defined as cases in which stenosis or other mucosal lesions are not observed on the capsule endoscope and remain in the same position for more than 60 minutes, or cases in which mucosal lesions are confirmed and remain in the same position for more than 60 minutes.

However, there is a problem in that, although not a large percentage of the residual phenomenon and local transit anomalies of the capsule endoscope occur, cases where removal surgery is often required due to being caught in an acute or stricture site. In order to minimize the occurrence of these problems, the need for a prior examination to prevent the retention of the capsule endoscope prior to examination using the capsule endoscope is increasing.

Data on the location signal of the capsule device 100 for testing stored in step S500 is transmitted to the external device P (S700). In step S700, data on the position signal of the capsule device 100 for testing is transmitted to an external device P such as a computer or an imaging device, so that overall test results can be analyzed before the capsule endoscope test.
