Body-insertable device system and body-insertable device guiding method
First Claim
1. A body-insertable device system comprising:
- a body-insertable device containing therein an imaging unit which picks up images of an inside of a subject and a magnetic material;
a magnetic field generating unit which generates a magnetic field to the magnetic material of the body-insertable device having been introduced into the subject and changes at least one of a position and a posture of the body-insertable device by the magnetic field; and
a position presenting unit which visually presents an approaching position where the magnetic field generating unit is to be approached on the subject.

Abstract
An object of the present invention is that the examiner easily picks up a series of images over a desired region in a desired digestive tract without such troublesome examination work that the examiner successively knows the imaging field to the inside of the digestive tract. A body-insertable device system of the invention includes a capsule endoscope 1, a permanent magnet 3, and a position display sheet 2. In the capsule endoscope 1, a imaging unit for picking up the images of the insides of an subject 100, and a magnet are contained in a casing. The capsule endoscope sends a radio signal containing information of the images of the insides of the subject 100 to outside the capsule endoscope. The permanent magnet 3 generates a magnetic field for application to the capsule endoscope 1 in liquid Lq1 having been introduced into the subject 100 and changes at least one of a position and a posture of the capsule endoscope 1 by the magnetic field. The position display sheet 2 visually presents an approaching position of the subject 100 that the permanent magnet 3 approaches to generate a magnetic field.
