Abstract:
1. A body-insertable apparatus inserted into a subject to move in the subject, comprising: an in-vivo information acquiring unit acquiring in-vivo information of the subject; an external case member accommodating the in-vivo information acquiring unit; and a moving-speed suppressing unit positioned inside or outside of the external case member to generate a predetermined suppressing force for suppressing a moving speed in between an inner wall of a passage route in the subject and the body-insertable apparatus, wherein the moving-speed suppressing unit includes an adhering mechanism that adheres to an inner wall of the passage route with a predetermined strength by sucking external fluid present near a suction-side opening via the suction-side opening, the adhering mechanism comprising a soft tube member that connects the suction-side opening to a discharge-side opening and a suction operation generator that changes a shape of the soft tube member so that the external fluid is sucked via the suction-side opening and discharged from the discharge-side opening via the soft tube member wherein the external case member accommodates the adhering mechanism, has the suction-side opening formed in a region of the external case member and the external case member has the discharge-side opening formed in a region other than the region where the suction-side opening is formed.
