Abstract

A capsule endoscope system provided with a magnetic field generating apparatus including an input section for inputting identification information A and a magnetic field generating section that generates a magnetic field signal that controls a capsule endoscope, and the capsule endoscope including an in-vivo information acquiring section, a battery, a magnetic field receiving section, a storage section that stores identification information B, a control section and a comparing section that compares the identification information A with the identification information B and judges whether both pieces of information are the same or different, wherein when the judgment by the comparing section is a judgment that both pieces of information are the same, the control section supplies or shuts off power from the battery to the in-vivo information acquiring section.

Dependent claims

An in-vivo information acquiring system comprising:

a magnetic field generating apparatus comprising
an input section for inputting first identification information that allows an in-vivo information acquiring apparatus to be controlled to be distinguished from other in-vivo information acquiring apparatuses, and
a magnetic field generating section that generates a magnetic field signal that controls the in-vivo information acquiring apparatus to be controlled;
and
an in-vivo information acquiring apparatus introduced into an object to be examined and to be controlled, comprising
an in-vivo information acquiring section that acquires information inside the object to be examined,
a power supply source that supplies power to be used to drive the in-vivo information acquiring section,
a magnetic field signal receiving section disposed outside that receives the magnetic field signal from the external signal generating apparatus,
a storage section that stores second identification information that allows the in-vivo information acquiring apparatus to be controlled to be distinguished from the other in-vivo information acquiring apparatuses, and
a power supply control section that controls a power supply from the power supply source to the in-vivo information acquiring section,
wherein when the in-vivo information acquiring system has any one of configurations where (1) the magnetic field generating apparatus comprises a first comparing section that compares the first identification information with the second identification information and judges whether both pieces of information are the same or different, (2) the in-vivo information acquiring apparatus to be controlled comprises a second comparing section that compares the first identification information with the second identification information and judges whether both pieces of information are the same or different and (3) the magnetic field generating apparatus comprises the first comparing section and the in-vivo information acquiring apparatus to be controlled comprises the second comparing section, and
when the judgment of at least one of the first comparing section and the second comparing section is a judgment that both pieces of information are the same, the power supply control section supplies or shuts off power from the power supply source to the in-vivo information acquiring section.
