1. A capsulated medical equipment comprising:
- a capsulated body adapted to be inserted into a subject, the capsulated body comprising;
a biomedical information detecting unit adapted to obtain biomedical information about the subject,a communication device adapted to modulate the biomedical information into a signal to be transmitted, andan antenna for transmitting the signal to outside of the subject; and
a receiver located outside of the subject and adapted to be carried by the subject, the receiver comprising;
an extracorporeal antenna unit adapted to receive the signal transmitted from the antenna of the capsulated body,a demodulation unit adapted to demodulate the received signal to create a biomedical information data of the subject;
a first storage device adapted to store the biomedical information data,a first display for displaying information,a position calculation section adapted to calculate a three-dimensional position of the capsulated body based on the strength of the received signal, anda position change calculation unit adapted to calculate a change in three-dimensional position of the capsulated body over time, to judge whether the calculated change in three-dimensional position over time is equal to or smaller than a pre-set threshold, and if the calculated change in three-dimensional position over time is judged to be equal to or smaller than the pre-set threshold, to instruct the first display to display a warning message;
wherein the first storage device is connectable to a second storage device which stores therein the biomedical information data and which is connected to a second display for displaying the biomedical information data read from the second storage device.

Abstract
A capsulated body having a facility, which acquires biomedical information through endoscopic examination or the like, incorporated therein is inserted into a duct within a living body. Whether the capsulated body has halted for a certain period of time is detected from the time-varying position of the capsulated body or a time-passing change in an image. If it is judged that the capsulated body has halted at a stenosed region or the like, the fact is notified so that the capsulated body can be collected immediately.
