SYSTEM FOR GUIDING CAPSULE MEDICAL DEVICE AND METHOD OF CONTROLLING THE SAME

摘要

An encapsulated medical device system according to an embodiment of the present invention includes a selector 8 between a receiving device 9 and a plurality of receiving antennas 7 having their respective directionalities. The system selects and disconnects any receiving antenna 7 subjected to the effect of a magnetic field used to guide a capsule endoscope 21, and captures information about the inside of a body from the appropriate receiving antenna 7 thus selected. The system prevents an overload current caused by induced voltage from being applied to the receiving device 9. The system includes the function of preventing the overload current, caused by induced voltage arising from a sudden movement of the capsule endoscope 21 or sudden change in magnetic field gradient, from being applied to a transmission circuit 36 of the capsule endoscope 21 and a receiving device 9.
