Patent ID: 8731637

Claim:
An intra-subject medical system comprising: a body-insertable device to be introduced into a subject, the body-insertable device being covered by a capsule-shaped exterior member and including: a physical quantity detecting member which has a directivity to detect a predetermined physical quantity; at least one functional member which has a necessary function for examining or treating inside the subject; and a switch control unit which controls an on/off state or operation mode of the at least one functional member according to a detection result of a physical quantity by the physical quantity detecting member; a physical quantity generator including a physical quantity emitting unit adapted to emit a temporary physical quantity inside the subject; a physical quantity direction changing unit which changes an emission direction of the physical quantity; and a control unit which controls the physical quantity emission by the physical quantity emitting unit and the direction of the physical quantity emission by the physical quantity direction changing unit, wherein the control unit is configured to determine whether the on/off state or operation mode of the at least one functional member is controlled by the switch control unit in response to the physical quantity emitted by the physical quantity emitting unit, wherein: when the on/off state or operation mode of the at least one functional member is not controlled by the switch control unit in response to the physical quantity emitted by the physical quantity emitting unit, the control unit changes the direction of the physical quantity emission and then performs the physical quantity emission, and when the on/off state or operation mode of the at least one functional member is controlled by the switch control unit in response to the physical quantity emitted by the physical quantity emitting unit, the control unit controls to stop further physical quantity emission.
