Patent ID: 8734329

Claim:
A capsule medical device guiding system, comprising: a capsule medical device including a permanent magnet and introduced into a liquid in a subject; a magnetic field generating unit configured to generate a magnetic field applied to the permanent magnet to guide the capsule medical device, and change a direction of the generated magnetic field in a three-dimensional space; a control unit configured to control the magnetic field to be generated by the magnetic field generating unit; a first manipulation input unit configured to instruct the control unit to apply a single magnetic field; and a second manipulation input unit configured to instruct the control unit to apply first and second magnetic fields simultaneously, wherein the control unit controls the magnetic field generating unit to generate the single magnetic field in response to instructions from the first manipulation input unit, and in a state where the capsule medical device is located on a liquid surface of the liquid, the control unit causes the first magnetic field to be generated such that a plane, which is parallel to a vertical axis and in which a magnetic field including a rotating magnetic field where a magnetic field is rotated on the plane is generated, pivots about the vertical axis at a predetermined period, and causes the second magnetic field to be generated for generating a magnetic attracting force for moving the permanent magnet vertically downward to submerge the capsule medical device in the liquid, and controls the first and second magnetic fields to be applied simultaneously, in response to instructions from the second manipulation input unit.
