摘要： A capsule endoscope includes a capsule-shaped casing and an imaging unit for taking an image of an inside of an organ in a state where the capsule endoscope is floating in liquid introduced inside the organ of a subject. Specific gravity of the capsule endoscope to the introduced liquid is ρ; a plane divides the capsule endoscope such that a volume ratio is to be ρ:1−ρ. A straight line that connects a center of volume of a portion whose volume ratio is ρ and a center of gravity of the capsule endoscope is substantially perpendicular to the plane. The center of gravity is present at a position farther distant from the plane than the center of volume. A surface of a boundary of a field of view that forms an angle of view of the imaging unit and the plane do not intersect outside the capsule endoscope.

摘要： A body-insertable apparatus which can make the volume smaller by simplifying a mechanism taking in or throwing out predetermined fluid is realized. The body-insertable apparatus has a configuration having, in a housing, a balloon member, a communication adjusting mechanism, a control circuit, and a power source part and forms a storage chamber by the balloon member and an outer circumferential member (sheet holding substrate and part of the housing) covering the outer surface of the balloon member. In the body-insertable apparatus, a first communication pipe communicated with the inner space of the balloon member and a second communication pipe communicated with the outer space are formed. The communication adjusting mechanism communicates the first communication pipe with the second communication pipe based on an electric current output from the control circuit. The inner space of the balloon member is communicated with the outside of the body-insertable apparatus. The outside fluid is flowed into the storage chamber via an inlet with the contracting operation of the balloon member.

摘要： 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.

摘要： A system for guiding capsule medical device includes a capsule medical device that includes a capsule casing including an imaging unit and a permanent magnet magnetized in a direction relatively fixed with respect to an upward and downward direction of an imaging surface of the imaging unit. The capsule medical device has a center of gravity deviated from a geometric center of the casing toward a direction different from a magnetization direction of the permanent magnetic. In the capsule medical device, a plane parallel to the imaging surface and a plane parallel to the magnetization direction and a deviation direction of the center of gravity with respect to the geometric center form an intersection line. The system further includes a magnetic guidance device; and an image display device displaying an in-vivo image such that a direction of the intersection line conforms to an upward and downward direction of a screen.
