CAPSULE-TYPE MEDICAL DEVICE AND METHOD OF MONITORING ESOPHAGUS INSIDE AND STOMACH INSIDE, METHOD OF MONITORING STOMACH INSIDE AND METHOD OF WASHING STOMACH USING THE SAME

摘要

An object of the invention is to capable of reducing the surface tension of liquid that is applied so as to bring a casing into contact with an organ wall, and easily separating a casing from an organ wall even though the casing comes into contact with the organ wall while being floated on a liquid surface in an organ. The specific gravity of a capsule-type endoscope 1 according to the invention is set to be lower than that of liquid in an organ, so that the capsule-type endoscope is floated on a liquid surface S of the liquid. A center of gravity G of the capsule-type endoscope is set to a position deviated from a center C of a casing 2, so that the casing 2 is maintained in a specific floating position while being floated on the liquid surface S. A boundary B between the casing 2 and the liquid surface S is formed within a projection plane Ka, which is obtained by projecting the casing 2 in the specific floating position perpendicularly to the liquid surface S, at a position excluding an outer periphery Kb of the projection plane Ka.
